Patient perspectives on recall period and response options in patient-reported outcome measures for chronic rhinosinusitis symptomatology: An international multi-centered study

BACKGROUND

Existing patient-reported outcome measures (PROMs) for chronic rhinosinusitis (CRS) use a variety of recall periods and response scales to assess CRS symptom burden. Global perspectives of CRS patients regarding optimal recall periods and response scales for CRS PROMs are unknown.

METHODS

This was a multi-center, cross-sectional study recruiting 461 CRS patients from sites across the United States, Saudi Arabia, New Zealand, and Austria. Participants chose which CRS symptom recall period (1 day, 2 weeks, 1 month, >1 month) was most reflective of their current disease state and upon which to best base treatment recommendations (including surgery). Participants also chose which of six response scales (one visual analogue scale and five Likert scales ranging from four to eight items) was easiest to use, understand, and preferred.

RESULTS

A plurality of participants (40.0%) felt their CRS symptoms' current state was best reflected by a 1-month recall period. However, most patients (56.9%) preferred treatment recommendations to be determined by symptoms experienced over a >1 month period. The four- and five-item Likert scales were the easiest to understand (26.0% and 25.4%, respectively) and use (23.4% and 26.7%, respectively). The five-item (26.4% rating it most preferred and 70.9% rating it preferred) and four-item Likert (22.3% rating it most preferred and 56.4% rating it preferred) response scales were most preferred.

CONCLUSION

Future PROMs for CRS should consider assessment of symptoms over a 1-month period and use a four- or five-item Likert response scale to reflect global patient preferences. These findings also inform interpretation of current CRS PROMs.

Treatment of unilateral olfactory neuroblastoma: Appropriate extent of surgical resection and potential for olfactory preservation

Historically, comprehensive surgical resection for olfactory neuroblastoma has included the bilateral olfactory epithelium, cribriform plate, overlying dura, olfactory bulbs and tracts. This results in postoperative anosmia that may significantly impact a patient's quality of life without definitive added benefit in survival. The prevalence of occult intracranial disease is low, especially for Hyams grade I and II tumors. A unilateral approach sparing the contralateral cribriform plate and olfactory system can be considered for select cases of early stage, low-grade tumors when the disease does not cross midline to involve the contralateral olfactory cleft or septal mucosa and when midline dural margins can be cleared with frozen pathology. Approximately half of patients who undergo unilateral resection may have residual olfaction even with adjuvant unilateral radiation. Early data suggest favorable disease-free survival and overall survival for patients who underwent the unilateral approach; however, larger sample studies are needed to confirm comparability to bilateral resections regarding oncologic outcomes.

Comparison of patient-reported outcomes and clinical characteristics among patients with pituitary macroadenomas and giant adenomas

KEY POINTS

Patients with giant adenomas are more likely to have tumor extension into the paranasal sinuses. Compared to macroadenomas, giant adenomas are not associated with worse preoperative SNOT-22 scores.

Clinical Productivity and Patient Complexity of Academic Rhinologists: An Analysis of Medicare Metrics

INTRODUCTION

Current data regarding reimbursement trends in Medicare services and the complexity of patients treated as physicians' progress in their academic career are conflicting. In otolaryngology, there are no data examining these metrics.

METHODS

Medicare services, reimbursement, and patient complexity risk scores (based on hierarchical condition category coding) of US rhinology fellowship-trained faculty were stratified and compared by rank and years in practice.

RESULTS

A cohort of 209 rhinologists were included. Full professors were reimbursed more per service than assistant professors ($791.53 [$491.69-1052.46] vs. $590.34 [$429.91-853.07] p = 0.045) and had lower risk scores (1.37 [1.26-1.52] vs. 1.49 [1.29-1.68], p = 0.013). Full professors had similar risk scores to associate professors (1.47 [1.25-1.64], p = 0.14). Full professors ($791.53 [$491.69-1,052.46], p < 0.001), associate professors ($706.85 [$473.48-941.15], p < 0.001), and assistant professors ($590.34 [$429.91-853.07], p < 0.001) were all reimbursed more per service than non-ranked faculty ($326.08 [$223.37-482.36]). As a cohort, significant declines in risk scores occurred within the 10th-14th year of practice (p = 0.032) and after the 20th year (p = 0.038). Years in practice were inversely correlated with risk score (R = -0.358, p < 0.001).

CONCLUSION

Full professors were reimbursed more per service and treated less comorbid Medicare patients than junior academic colleagues. Patient comorbidity was correlated negatively with years in practice, with significant drops in mid and late career. Rhinologists employed at academic institutions had greater total reimbursement and reimbursement per service than non-ranked faculty.

Endoscopic Repair of Anterior Skull Base Cerebrospinal Fluid Leaks is Successful in Frail Patients

OBJECTIVE

Surgical frailty estimates a patient's ability to withstand the physiologic stress of an intervention. There is limited data regarding the impact of frailty on endoscopic cerebrospinal fluid (CSF) leak repair.

METHODS

Patients undergoing CSF leak repair at two tertiary academic skull base programs were retrospectively reviewed. Demographic, treatment, and postoperative outcomes data were recorded. Frailty was calculated using validated indices, including the American Society of Anesthesiologists (ASA) classification, Charlson Comorbidity Index (CCI), and the Modified 5-Item Frailty Index (mFI-5). Outcomes included 30-day medical and surgical complications and readmission.

RESULTS

A total of 185 patients were included with 128 (69.2%) female patients and average age of 54 ± 14 years. The average body mass index was 34.6 ± 8.5. The most common identified etiology was idiopathic intracranial hypertension (IIH) in 64 patients (34.6%). A total of 125 patients (68%) underwent perioperative lumbar drain placement (primarily to measure intracranial pressures and diagnose IIH). Most patients were ASA class 3 (48.6%) with mean CCI 2.14 ± 2.23 and mFI-5 0.97 ± 0.90. Three patients had postoperative CSF leaks, with an overall repair success rate of 98.4%. There was no association between increased frailty and 30-day medical outcomes, surgical outcomes, or readmission (all p > 0.05).

CONCLUSIONS

Endoscopic CSF leak repair in a frail population, including lumbar drain placement and bed rest, was not associated with an increased rate of complications. Previous data suggests increased complications in open craniotomy procedures in patients with significant comorbidities. This study suggests that the endoscopic approach to CSF leak repair is well tolerated in the frail population.

Staged Resection of Difficult-to-Treat Intracranial Meningiomas: A Systematic Review of the Indications, Surgical Approaches, and Postoperative Outcomes

Introduction  Meningiomas-the most common extra-axial tumors-are benign, slow-growing dural-based lesions that can involve multiple cranial fossae and can progress insidiously for years until coming to clinical attention secondary to compression of adjacent neurovascular structures. For complex, multicompartmental lesions, multistaged surgeries have been increasingly shown to enhance maximal safe resection while minimizing adverse sequela. Here, we systematically review the extant literature to highlight the merits of staged resection. Methods  PubMed, Scopus, and Web of Science databases were queried to identify articles reporting resections of intracranial meningiomas using a multistaged approach, and articles were screened for possible inclusion in a systematic process performed by two authors. Results  Of 118 identified studies, 36 describing 169 patients (mean age 42.6 ± 21.3 years) met inclusion/exclusion criteria. Petroclival lesions comprised 57% of cases, with the most common indications for a multistaged approach being large size, close approximation of critical neurovascular structures, minimization of brain retraction, identification and ligation of deep vessels feeding the tumor, and resection of residual tumor found on postoperative imaging. Most second-stage surgeries occurred within 3 months of the index surgery. Few complications were reported and multistaged resections appeared to be well tolerated overall. Conclusions  Current literature suggests multistaged approaches for meningioma resection are well-tolerated. However, there is insufficient comparative evidence to draw definitive conclusions about its advantages over an unstaged approach. There are similarly insufficient data to generate an evidence-based decision-making framework for when a staged approach should be employed. This highlights the need for collaborative efforts among skull base surgeons to establish an evidentiary to support the use of staged approaches and to outline those indications that merit such an approach.

Mutational landscape and predictors of survival in head and neck mucosal melanoma

KEY POINTS

Head and neck mucosal melanomas have a diverse mutational landscape with low mutational burden. A molecular subset (∼13%) has ROS1 mutations, which is an actionable driver mutation. ROS1-mutated patients have improved overall survival likely due to high mutational burden.

Anatomic Relationship Between the Head of the Middle Turbinate and First Olfactory Filum: A Radiographic Assessment

BACKGROUND

The endoscopic modified Lothrop procedure (EMLP) has become a frequently utilized procedure in rhinologic surgery. One of the most serious complications of the procedure is cerebrospinal fluid leak, which may occur due to lack of recognition of the anterior skull base in the region of the first olfactory filum (FOF), or direct injury to the FOF itself.

OBJECTIVES

To evaluate the position of the head of the middle turbinate (MT) relative to the FOF, which is an important landmark in the EMLP.

METHODS

A series of previously obtained patient computed tomography scans of the sinus were reviewed. A reproducible process was implemented to obtain the measurements. First, the FOF was identified on an axial series. Using a localization feature of the radiographic software, this anteroposterior (AP) position could be visualized in a coronal plane. Subsequently, the MT was viewed in a sagittal plane, where a measurement between the head of the MT and the AP position of the FOF could be performed.

RESULTS

The AP distance between the head of the MT and the FOF was measured in 92 patients. The head of the MT was either at or anterior to the FOF in all measured subjects. The mean anterior distance of the head of the MT to FOF was 3.6 mm (±2.4 mm) on the right, and 3.8 mm (±2.2 mm) on the left. The range in AP distance was 0 to 12 mm. There was no significant difference in AP distance between the head of the MT and FOF based on gender (P = .413) or diagnosis (P = .254).

CONCLUSIONS

In our study, the head of the MT was reliably at or anterior to the FOF in all subjects, suggesting its utility as a fixed landmark in endoscopic sinus surgery, particularly in the EMLP.

Predictive factors for decreased baseline quality of life in patients with sinonasal malignancies

BACKGROUND

The impact of sinonasal malignancies (SNMs) on quality of life (QOL) at presentation is poorly understood. The Sinonasal Outcome Test (SNOT-22) and University of Washington Quality of Life (UWQOL) are validated QOL instruments with distinctive subdomains. This study aims to identify factors impacting pretreatment QOL in SNM patients to personalize multidisciplinary management and counseling.

METHODS

Patients with previously untreated SNMs were prospectively enrolled (2015-2022) in a multicenter observational study. Baseline pretreatment QOL instruments (SNOT-22, UWQOL) were obtained along with demographics, comorbidities, histopathology/staging, tumor involvement, and symptoms. Multivariable regression models identified factors associated with reduced baseline QOL.

RESULTS

Among 204 patients, presenting baseline QOL was significantly reduced. Multivariable regression showed worse total SNOT-22 QOL in patients with skull base erosion (p = 0.02). SNOT-rhinologic QOL was worse in women (p = 0.009), patients with epistaxis (p = 0.036), and industrial exposure (p = 0.005). SNOT extranasal QOL was worse in patients with industrial exposure (p = 0.016); worse SNOT ear/facial QOL if perineural invasion (PNI) (p = 0.027). Squamous cell carcinoma pathology (p = 0.037), palate involvement (p = 0.012), and pain (p = 0.017) were associated with worse SNOT sleep QOL scores. SNOT psychological subdomain scores were significantly worse in patients with palate lesions (p = 0.022), skull base erosion (p = 0.025), and T1 staging (p = 0.023). Low QOL was more likely in the presence of PNI on UW health (p = 0.019) and orbital erosion on UW overall (p = 0.03). UW social QOL was worse if palatal involvement (p = 0.023) or PNI (p = 0.005).

CONCLUSIONS

Our findings demonstrate a negative impact on baseline QOL in patients with SNMs and suggest sex-specific and symptom-related lower QOL scores, with minimal histopathology association. Anatomical tumor involvement may be more reflective of QOL than T-staging, as orbital and skull base erosion, PNI, and palate lesions are significantly associated with reduced baseline QOL.

Trends in Botulinum Toxin-Related Industry Payments to Physicians

Objectives: To evaluate trends in botulinum toxin (BTX) industry payments to physicians. Methods: Cross-sectional analysis of nonroyalty, BTX-specific payments made by Allergan (Botox), Ipsen (Dysport), and Merz (Xeomin) to physicians using the 2016-2020 Open Payments Database. Results: Between 2016 and 2020, >$27 million in payments was made for BTX-related activities to dermatologists, neurologists, ophthalmologists, otolaryngologists, and plastic surgeons, with payments ranging from $3.9 million in 2016 to $8.7 million in 2019. 21.7% was paid to dermatologists, 57.5% to neurologists, 5.9% to ophthalmologists, 5.7% to otolaryngologists, and 9.1% to plastic surgeons. Conclusions: Growing amounts are being paid to physicians for BTX-related activities-both medical and aesthetic. Despite the variety of indications for BTX within otolaryngology, otolaryngology payments were overshadowed by other specialties, which may reflect greater BTX utilization in those specialties.

Tissue Sealant Impact on Skull Base Reconstruction Outcomes: A Systematic Review and Meta-Analysis

OBJECTIVE

Despite significant advances in understanding of skull base reconstruction principles, the role of tissue sealants in modifying postoperative cerebrospinal fluid (CSF) leak outcomes remains controversial. We evaluate postoperative CSF leak incidence associated with tissue sealant use in skull base defect repair during endoscopic skull base surgery (ESBS).

DATA SOURCES

Web of Science, PubMed/MEDLINE, Scopus, and Cochrane Library.

REVIEW METHODS

Systematic review and meta-analysis of risk differences (RD). A search strategy identified original studies reporting CSF leakage following ESBS with disaggregation by tissue sealant use and/or type.

RESULTS

27 non-randomized studies (n = 2,403) were included for qualitative and meta-analysis. Reconstruction with a tissue sealant did not significantly reduce postoperative CSF leak risk compared with reconstruction without sealant (RD[95% CI] = 0.02[-0.01, 0.05]). Sub-analyses of dural sealant (-0.02[-0.11, 0.07]) and fibrin glue (0.00[-0.07, 0.07]) compared with no sealant were similarly unremarkable. Postoperative CSF leakage was not significantly modulated in further sub-analyses of DuraSeal (0.02[-0.02, 0.05]), Adherus (-0.03[-0.08, 0.03]), or Bioglue (-0.06[-0.23, 0.12]) versus no dural sealant use, or Tisseel/Tissucol versus fibrin glue nonuse (0.00[-0.05, 0.05]). No significant association was seen comparing dural sealant use versus fibrin glue use on pairwise (0.01[-0.03, 0.05]) or network meta-analysis (-0.01[-0.05, 0.04]). Limitations in source literature prevented sub-analyses stratified by leak characteristics, defect size and location, and accompanying reconstruction materials.

CONCLUSION

Tissue sealant use did not appear to impact postoperative CSF leak incidence when compared with nonuse. Higher quality studies are warranted to thoroughly elucidate the clinical value of adjunct sealant use in endoscopic skull base reconstruction.

The impact of nasal packing on skull base reconstruction and quality-of-life outcomes following endoscopic skull base surgery

KEY POINTS

Nasal packing type was not associated with postoperative cerebrospinal fluid leaks Nondissolvable packing conferred an increased risk for postoperative sinonasal infections Nasal packing type did not influence short- and long-term quality-of-life scores.

Impact of facility volume on survival in primary endoscopic surgery for sinonasal squamous cell carcinoma

OBJECTIVES

To evaluate the impact of facility volume on outcomes following primary endoscopic surgical management of sinonasal squamous cell carcinoma (SNSCC).

METHODS

The 2010-2016 National Cancer DataBase (NCDB) was queried for patients diagnosed with T1-T4a SNSCC surgically treated endoscopically as the primary treatment modality. Factors associated with overall survival (OS) were evaluated, including facility volume.

RESULTS

A total of 330 patients who underwent endoscopic surgical management of SNSCC were treated at 356 unique facilities designated as either low-volume (LVC; treating 1-2 cases; 0-75th percentile), intermediate-volume centers (IVC; 3-4 cases total; 75th-90th percentile), or 144 high-volume (HVC; treating 5+ cases total; >90th percentile) centers. HVC treated patients with higher T staging (42.1 % vs. 29.8 %) and tumors in the maxillary sinus (26.9 % vs. 13.2 %) and ethmoid sinus (10.3 % vs. ≤8.3 %), while LVCs treated lower T stage tumors (70.2 % vs. 57.9 %) and tumors that were located in the nasal cavity (70.2-78.5 % vs. 62.8 %). On multivariable analysis, factors associated with decreased OS included higher T stage (T3/T4a vs. T1/T2; OR 1.92, 95 % CI 1.06-3.47) and older age (>65 vs. <65; OR 2.69, 95 % CI 1.62-4.49). Cases treated at high-volume centers were not associated with a higher likelihood of OS when compared to low-volume centers (OR 0.70, 95 % CI 0.36-1.35).

CONCLUSIONS

HVC are treating more primary tumors of the maxillary and ethmoid sinuses and tumors with higher T stages with endoscopic approaches, although this does not appear to be associated with increased OS.

SHORT SUMMARY

Sinonasal squamous cell carcinoma (SNSCC) presents late in disease process with poor prognosis. We investigated the impact of facility volume on outcomes following endoscopic treatment of SNSCC. High-volume centers treat more advanced and complex disease with comparable OS.

Chronic Sphenoiditis With Deep Neck Space Extension: Case Report With Review of the Literature and Postulated Mechanisms for Extracranial Extension

Isolated primary sphenoid sinusitis is a rare occurrence, estimated to make up less than 3% of sinus infections. The posterior anatomic location of the sphenoid makes treatment challenging when it becomes infected. Complications involving intracranial extension to surrounding structures often result in cranial nerve deficits due to their proximity. A single case of chronic sphenoiditis with direct extracranial extension into the prevertebral space is reported with a discussion on clinical presentation, diagnosis, and management. A 46-year-old female patient with diffuse headaches radiating into the neck and throat was evaluated in the office. Computed tomography demonstrated sphenoiditis with direct extension into the prevertebral space. Imaging revealed a purported route of direct extension through the clinoid and directly into the clivus to form an abscess in the longus colli muscle. The patient underwent endoscopic surgical management including drainage of the prevertebral abscess and has since made a full recovery. This is the first reported case of direct extension of sphenoiditis into the prevertebral space. The findings highlight the importance of aggressive treatment of chronic sphenoid infections to prevent detrimental complications. Computed tomography imaging proved an advantageous imaging modality to demonstrate bony erosion and sinus tracts from the skull base to the deep neck space.

SNOT-22 subdomain outcomes following treatment for sinonasal malignancy: A prospective, multicenter study

BACKGROUND

Patients with sinonasal malignancy (SNM) present with significant sinonasal quality of life (QOL) impairment. Global sinonasal QOL as measured by the 22-item Sinonasal Outcomes Test (SNOT-22) has been shown to improve with treatment. This study aims to characterize SNOT-22 subdomain outcomes in SNM.

METHODS

Patients diagnosed with SNM were prospectively enrolled in a multi-center patient registry. SNOT-22 scores were collected at the time of diagnosis and through the post-treatment period for up to 5 years. Multivariable regression analysis was used to identify drivers of variation in SNOT-22 subdomains.

RESULTS

Note that 234 patients were reviewed, with a mean follow-up of 22 months (3 months-64 months). Rhinologic, psychological, and sleep subdomains significantly improved versus baseline (all p < 0.05). Subanalysis of 40 patients with follow-up at all timepoints showed statistically significant improvement in rhinologic, extra-nasal, psychological, and sleep subdomains, with minimal clinically important difference met between 2 and 5 years in sleep and psychological subdomains. Adjuvant chemoradiation was associated with worse outcomes in rhinologic (adjusted odds ratio (5.22 [1.69-8.66])), extra-nasal (2.21 [0.22-4.17]) and ear/facial (5.53 [2.10-8.91]) subdomains. Pterygopalatine fossa involvement was associated with worse outcomes in rhinologic (3.22 [0.54-5.93]) and ear/facial (2.97 [0.32-5.65]) subdomains. Positive margins (5.74 [2.17-9.29]) and surgical approach-combined versus endoscopic (3.41 [0.78-6.05])-were associated with worse psychological outcomes. Adjuvant radiation (2.28 [0.18-4.40]) was associated with worse sleep outcomes.

CONCLUSIONS

Sinonasal QOL improvements associated with treatment of SNM are driven by rhinologic, extra-nasal, psychological, and sleep subdomains.

Severe unilateral refractory epistaxis arising from the septal branch of the anterior ethmoid artery

KEY POINTS

The septal branch of the anterior ethmoid artery (sbAEA) is an underrecognized source of severe refractory epistaxis. Herein, we describe the presentation, predisposing factors, treatment strategies, and outcomes of a series of patients with this condition.

Complications of Novel Radiofrequency Device Use in Rhinology: A MAUDE Analysis

With the widespread adoption of intranasal radiofrequency (RF) devices, our objective was to report national adverse events (AEs) associated with their use. The Food and Drug Administration's Manufacturer and User Facility Device Experience was queried. A total of 24 device-related AEs were reported, 11 (45.8%) for Celon® (Olympus), 3 (12.5%) for Vivaer® (Aerin), 2 (8.3%) for Neuromark® (Neurent), and 8 (33.3%) for Rhinaer® (Aerin). Seven (63.6%) of the Celon®-related complications were related to tissue necrosis (largely user error-related), but 1 (9.1%) episode of pediatric ocular palsy was also reported. Vivaer® complications included synechiae formation, a mucosal perforation, and a case of empty nose syndrome. Of the posterior nasal nerve ablating devices, 9 of 10 AEs were epistaxes, of which 7 (77.8%) required operative intervention. Surgeons should exercise vigilance and tissue-appropriate device settings when utilizing RF devices. Epistaxis and tissue necrosis may occur, as well as more rare, but devastating, complications.

International Consensus Statement on Allergy and Rhinology: Sinonasal Tumors

BACKGROUND

Sinonasal neoplasms, whether benign and malignant, pose a significant challenge to clinicians and represent a model area for multidisciplinary collaboration in order to optimize patient care. The International Consensus Statement on Allergy and Rhinology: Sinonasal Tumors (ICSNT) aims to summarize the best available evidence and presents 48 thematic and histopathology-based topics spanning the field.

METHODS

In accordance with prior International Consensus Statement on Allergy and Rhinology documents, ICSNT assigned each topic as an Evidence-Based Review with Recommendations, Evidence-Based Review, and Literature Review based on the level of evidence. An international group of multidisciplinary author teams were assembled for the topic reviews using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses format, and completed sections underwent a thorough and iterative consensus-building process. The final document underwent rigorous synthesis and review prior to publication.

RESULTS

The ICSNT document consists of four major sections: general principles, benign neoplasms and lesions, malignant neoplasms, and quality of life and surveillance. It covers 48 conceptual and/or histopathology-based topics relevant to sinonasal neoplasms and masses. Topics with a high level of evidence provided specific recommendations, while other areas summarized the current state of evidence. A final section highlights research opportunities and future directions, contributing to advancing knowledge and community intervention.

CONCLUSION

As an embodiment of the multidisciplinary and collaborative model of care in sinonasal neoplasms and masses, ICSNT was designed as a comprehensive, international, and multidisciplinary collaborative endeavor. Its primary objective is to summarize the existing evidence in the field of sinonasal neoplasms and masses.

Incidence and Reimbursement Trends for Facial Fracture Repair in the Elderly: A Medicare Analysis

OBJECTIVES

The aim was to describe incidence and reimbursement trends of surgical repair of facial fractures among the Medicare population.

METHODS

The annual procedure data from the Centers for Medicare and Medicaid Service National Part B Data File from 2000 to 2019 were queried.

RESULTS

The total number of surgically corrected facial fractures increased from 10,148 in 2000 to 19,631 in 2019 in a linear pattern (r = 0.924). Specifically, nasal bone/septum fracture repairs increased the most by 200.6% (n = 4682 to n = 14,075), whereas operations for TMJ dislocations, malar/zygoma fractures, and alveolar ridge/mandibular fractures decreased by 27.9%, 12.3%, and 3.2%, respectively, between 2000 and 2019. Correspondingly, the total Medicare reimbursement rose from $2,574,317 in 2000 to $4,129,448 in 2019 (r = 0.895). However, the mean reimbursement for all procedures decreased from $376.63 to $210.35 (44.1% fall) over the same time after adjusting for inflation, with this trend holding for individual fracture types as well.

CONCLUSIONS

Given the population's increasing age, there has been a significant increase in the number of surgical repairs of facial fractures in Medicare patients between 2000 and 2019. However, this is largely driven by an increase in nasal bone/septum closed reductions, with stagnant and, in some cases, declining incidence among other fracture repairs. The reason is unclear and may be related to an increase in nonoperative management or poor outcomes. Nevertheless, like other subfields within otolaryngology and medicine at large, payments have lagged far behind, which may play some role.

Impact of Frailty on Postoperative Outcomes in Extended Endonasal Skull Base Surgery for Suprasellar Pathologies

OBJECTIVE

Frailty metrics estimate a patient's ability to tolerate physiologic stress and there are limited frailty data in patients undergoing expanded endonasal approaches (EEA) for suprasellar pathologies. Elevated frailty metrics have been associated with increased perioperative complications in patients undergoing craniotomies. We sought to examine this potential relationship in EEA.

STUDY DESIGN

Retrospective cohort study.

SETTING

Two tertiary academic skull base centers.

METHODS

Cases of patients undergoing EEA for suprasellar pathologies were reviewed. Demographic, treatment, survival, and postoperative outcomes data were recorded. Frailty was calculated using validated indexes, including the American Society of Anesthesiologists (ASA) classification, the modified 5-item frailty index (mFI-5), and the Charlson comorbidity index (CCI). Primary outcomes included 30-day medical and surgical complications.

RESULTS

A total of 88 patients were included, with 59 (67%) female patients and a mean age of 54 ± 15 years. The most common pathologies included 53 meningiomas (60.2%) and 21 craniopharyngiomas (23.9%). Most patients were ASA class 3 (54.5%) with mean mFI-5 0.82 ± 1.01 and CCI 4.18 ± 2.42. There was no association between increased frailty and 30-day medical or surgical outcomes (including postoperative cerebrospinal fluid leak), prolonged length of hospital stay, or mortality (all P > .05). Higher mFI-5 was associated with an increased risk for 30-day readmission (odds ratio: 2.35, 95% confidence Interval: 1.10-5.64, P = .04).

CONCLUSION

Despite the patient population being notably frail, we only identified an increased risk for 30-day readmission and observed no links with deteriorating surgical, medical, or mortality outcomes. This implies that conventional frailty metrics may not effectively align with EEA outcomes.

Clinical and technical factors in endoscopic skull base surgery associated with reconstructive success

BACKGROUND

In this study, we identified key discrete clinical and technical factors that may correlate with primary reconstructive success in endoscopic skull base surgery (ESBS).

METHODS

ESBS cases with intraoperative cerebrospinal fluid (CSF) leaks at four tertiary academic rhinology programs were retrospectively reviewed. Logistic regression identified factors associated with surgical outcomes by defect subsite (anterior cranial fossa [ACF], suprasellar [SS], purely sellar, posterior cranial fossa [PCF]).

RESULTS

Of 706 patients (50.4% female), 61.9% had pituitary adenomas, 73.4% had sellar or SS defects, and 20.5% had high-flow intraoperative CSF leaks. The postoperative CSF leak rate was 7.8%. Larger defect size predicted ACF postoperative leaks; use of rigid reconstruction and older age protected against sellar postoperative leaks; and use of dural sealants compared to fibrin glue protected against PCF postoperative leaks. SS postoperative leaks occurred less frequently with the use of dural onlay. Body-mass index, intraoperative CSF leak flow rate, and the use of lumbar drain were not significantly associated with postoperative CSF leak. Meningitis was associated with larger tumors in ACF defects, nondissolvable nasal packing in SS defects, and high-flow intraoperative leaks in PCF defects. Sinus infections were more common in sellar defects with synthetic grafts and nondissolvable nasal packing.

CONCLUSIONS

Depending on defect subsite, reconstructive success following ESBS may be influenced by factors, such as age, defect size, and the use of rigid reconstruction, dural onlay, and tissue sealants.

Transoral robotic surgery in HPV+ oropharyngeal cancer of unknown primary

PURPOSE

This study was designed to assess trends in and outcomes associated with TORS-treated HNCUP using a large national database.

MATERIALS AND METHODS

HPV+ oropharyngeal HNCUPs were isolated from the 2004-2017 National Cancer Database. Overall survival (OS) was assessed, with patients stratified by 1) use of TORS and 2) whether the occult tumor was ultimately located. Demographic and oncologic predictors of survival were evaluated on regression.

RESULTS

The cohort contained 284,734 cases, of which 8336 were HNCUPs. HNCUPs represented 2.49 % of all HNSCC in 2010 versus 3.13 % in 2017. 3897 (46.7 %) of these unknown primaries were ultimately identified. The proportion of cases treated with TORS increased from 6.9 % in 2010 to 18.1 % in 2017 (p < 0.001). Kaplan-Meier analysis of 2991 HPV+ oropharyngeal HNCUPs demonstrated higher 5-year overall survival (OS) for patients treated with robotic surgery versus no robotic surgery (95.4 % ± 1.7 % standard error [SE] versus 84.0 % ± 0.9 % SE; p < 0.001). Patients with primary tumors identified during treatment had improved OS compared to those whose tumors were not located (5-year OS was 90.5 % ± 0.9 % SE and 77.3 % ± 1.5 % SE, respectively; p < 0.001). For patients in which the primary tumor was found, those who received robotic surgery survived longer than those who did not (96.5 % ± 1.4 % SE versus 89.1 % ± 1.0 % SE 5-year OS; p < 0.001). The relationship between TORS and OS remained significant on Cox regression controlling for confounders.

CONCLUSIONS

Use of TORS in the workup for HPV+ HNCUP is associated with higher rates of tumor identification and improved OS.

The impact of facility type and volume on treatment and overall survival in craniopharyngioma

BACKGROUND

Craniopharyngiomas are uncommon benign sellar and parasellar tumors with high overall survival (OS) and recurrence rates. Treatment is often surgical but may include adjuvant therapies. The impact of adjuvant therapy and surgical approach have been evaluated, however, facility volume and type have not. The purpose of this study is to analyze the influence of facility volume and type on treatment modalities, extent of surgery and survival of craniopharyngioma.

METHODS

The 2004-2016 National Cancer Database (NCDB) was queried for patients diagnosed with craniopharyngioma. Facilities were classified by type (academic vs. non-academic) and low-volume center (LVC) (Treating < 8 patients over the timeline) versus high-volume center (HVC), (Treating ≥ 8 patients over the timeline). Differences in treatment course, outcomes, and OS by facility type were assessed.

RESULTS

3730 patients (51.3% female) with mean age 41.2 ± 22.0 were included with a 5-year estimated OS of 94.8% (94.0-95.5%). 2564 (68.7%) patients were treated at HVC, of which 2142 (83.5%) were treated at academic facilities. Patients treated at HVC's were more likely to undergo both surgery and radiation. Surgical approach at HVC was more likely to be endoscopic. Patients treated at HVC demonstrated significantly higher 5-year OS compared to patients treated at LVC (96% [95% CI 95.6-97.1% versus 91.2% [95% CI 89-92.7%] with lower risk of mortality (Hazard ratio [95% CI] = 0.69 [0.56-0.84]).

CONCLUSION

Treatment of craniopharyngioma at HVC compared to LVC is associated with improved OS, lower 30- and 90-day postoperative mortality risk, and more common use of both radiotherapy and endoscopic surgical approach.

Racial and ethnic disparities in the presentation size and timing of pituitary adenomas resected via endoscopic endonasal approach

KEY POINTS

In a single-center cohort of pituitary adenoma patients, non-White race independently predicted larger tumor size at initial presentation. Uninsured patients suffered a significantly higher rate of pituitary apoplexy at initial presentation. Geographically distant care appeared to present a greater barrier for non-White and Hispanic patients relative to their White and non-Hispanic counterparts.

Recurrence patterns among patients with sinonasal mucosal melanoma: A multi-institutional study

OBJECTIVE

To evaluate recurrence patterns and survival after recurrence among patients with sinonasal mucosal melanoma (SNMM).

METHODS

This was a multi-institutional retrospective review from seven U.S. institutions of patients with SNMM from 1991 to 2022. Recurrence was categorized as local, regional, distant, or multifocal. Kaplan-Meier tests were used to evaluate disease-free survival (DFS), overall survival (OS), and post-recurrence survival (PRS) reported with standard errors (SE) and log-rank testing used for comparison. Cox-regression was further used, with hazard ratios (HR) and 95% confidence intervals (CI) reported.

RESULTS

Among 196 patients with SNMM, there were 146 patients with recurrence (74.5%). Among all patients, 60-month DFS (SE) was 15.5% (2.9%), 60-month OS (SE) was 44.7% (3.7%), mean age ± standard deviation at diagnosis was 69.7 ± 12.5 years, and 54.6% were female. In 26 patients who underwent primary treatment of the neck, 60-month DFS did not differ from no treatment (p > 0.05). Isolated distant recurrence was most common (42.8%), followed by local (28.3%), multifocal (20.7%), and regional recurrence (8.3%). Among patients with regional recurrence in the neck, there was no 60-month PRS benefit for patients undergoing salvage neck dissection or radiation (p > 0.05). Among patients with distant recurrence, only immunotherapy was associated with improved 12-month PRS (HR = 0.32, 95% CI = 0.11-0.92, p = 0.034), and no treatment group was associated with improved 24- or 60-month PRS (p > 0.05).

CONCLUSION

SNMM is associated with a high recurrence rate and poor survival. Primary treatment of the neck was not associated with reduced recurrence, and immunotherapy for treatment of distant recurrence was associated with increased 12-month PRS.

Identifying Core Journals in Otolaryngology: A Bibliometric Analysis

OBJECTIVES

As research in otolaryngology continues to expand rapidly, it is important to identify core journals to keep clinicians updated with the latest advances. This study is the first to characterize core journals in otolaryngology.

METHODS

Using h-index and impact factor (IF), the top 15 NLM-indexed otolaryngology journals were selected for analysis. The references from all articles published in these journals in one randomized quarter were compiled into a citation rank list, with the most cited journal ranked the highest. Citation zonal distribution analysis was conducted to identify the zonal distribution of otolaryngology journals.

RESULTS

A total of 3150 journals containing 26876 articles were cited in otolaryngology literature in April-June 2019. Laryngoscope was the most cited journal containing 1762 citations. IF is significantly associated with the h-index for the top 10 otolaryngology journals (p = 0.032). Three core journal zones were identified, with Zone 1 containing 8 journals, Zone 2 containing 36 journals, and Zone 3 containing 189 journals. A linear relationship between the log journal rank for Zones 1-3 and a cumulative number of citations was found (R2  = 0.9948).

CONCLUSION

Eight core journals for otolaryngology were identified: Laryngoscope, Otolaryngology-Head and Neck Surgery, Otology & Neurotology, JAMA Otolaryngology-Head & Neck Surgery, Head & Neck, European Archives of Oto-Rhino-Laryngology, International Journal of Pediatric Otorhinolaryngology, Annals of Otology, Rhinology & Laryngology. In the face of rapidly evolving research and a multitude of journals, the high citation density within these core journals highlights their utility in updating busy clinicians.

Long-term quality of life after treatment in sinonasal malignancy: A prospective, multicenter study

BACKGROUND

Quality of life (QOL) for individuals with sinonasal malignancy (SNM) is significantly under-studied, yet it is critical for counseling and may impact treatment. In this study we evaluated how patient, treatment, and disease factors impact sinonasal-specific and generalized QOL using validated metrics in a large cohort over a 5-year posttreatment time frame.

METHODS

Patients with SNM who underwent definitive treatment with curative intent were enrolled in a prospective, multisite, longitudinal observational study. QOL was assessed using the 22-item Sino-Nasal Outcome Test (SNOT-22) and University of Washington Quality of Life Questionnaire (UWQOL) instruments at pretreatment baseline and multiple follow-ups through 5 years posttreatment. Multivariable modeling was used to determine demographic, disease, and treatment factors associated with disease-specific and generalized physical and social/emotional function QOL.

RESULTS

One hundred ninety-four patients with SNM were analyzed. All QOL indices were impaired at pretreatment baseline and improved after treatment. SNOT-22 scores improved 3 months and UWQOL scores improved 6 to 9 months posttreatment. Patients who underwent open compared with endoscopic tumor resection had worse generalized QOL (p < 0.001), adjusted for factors including T stage. Pterygopalatine fossa (PPF) involvement was associated with worse QOL (SNOT-22, p < 0.001; UWQOL Physical dimension, p = 0.02). Adjuvant radiation was associated with worse disease-specific QOL (p = 0.03). Neck dissection was associated with worse generalized physical function QOL (p = 0.01). Positive margins were associated with worse generalized social/emotional function QOL (p = 0.01).

CONCLUSION

Disease-specific and generalized QOL is impaired at baseline in patients with SNM and improves after treatment. Endoscopic resection is associated with better QOL. PPF involvement, adjuvant radiation, neck dissection, and positive margins were associated with worse QOL posttreatment.

Determinants of physician assessment of chronic rhinosinusitis disease control using EPOS 2020 criteria and the importance of incorporating patient perspectives of disease control

BACKGROUND

We identify chronic rhinosinusitis (CRS) manifestations associated with how rhinologists assess CRS control, with a focus on patient perspectives (patient-reported CRS control).

METHODS

Fifteen rhinologists were provided with real-world data from 200 CRS patients. Participating rhinologists first classified patients' CRS control as "controlled," "partly controlled," and "uncontrolled" using seven CRS manifestations reflecting European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS) CRS control criteria (nasal obstruction, drainage, impaired smell, facial pain/pressure, sleep disturbance, use of systemic antibiotics/corticosteroids in past 6 months, and nasal endoscopy findings) and patient-reported CRS control. They then classified patients' CRS control without knowledge of patient-reported CRS control. Interrater reliability and agreement of rhinologist-assessed CRS control with patient-reported CRS control and EPOS guidelines were determined.

RESULTS

CRS control classification with and without knowledge of patient-reported CRS control was highly consistent across rhinologists (κw  = 0.758). Rhinologist-assessed CRS control agreed with patient-reported CRS control significantly better when rhinologists had knowledge of patient-reported CRS control (κw  = 0.736 vs. κw  = 0.554, p < 0.001). Patient-reported CRS control, nasal obstruction, drainage, and endoscopy findings were most strongly associated with rhinologists' assessment of CRS control. Rhinologists' CRS control assessments weakly agreed with EPOS CRS control guidelines with (κw  = 0.529) and without (κw  = 0.538) patient-reported CRS control. Rhinologists classified CRS as more controlled than EPOS guidelines in almost 50% of cases.

CONCLUSIONS

This study directly demonstrates the importance of patient-reported CRS control as a dominant influence on rhinologists' CRS control assessment. Knowledge of patient-reported CRS control may better align rhinologists' CRS control assessments and treatment decisions with patients' perspectives.

Postoperative Polyp Scale (POPS): Development of a New Sinonasal Polyp Grading Scale

OBJECTIVE

Commonly used endoscopic grading scales, such as the nasal polyp scale, inadequately describe the degree of polyposis found postoperatively in the paranasal sinus cavities. The purpose of this study was to create a novel grading system that more accurately characterizes polyp recurrence in postoperative sinus cavities, the Postoperative Polyp Scale (POPS).

METHODS

A modified Delphi method was utilized to establish the POPS using consensus opinion among 13 general otolaryngologists, rhinologists, and allergists. Postoperative endoscopy videos from 50 patients with chronic rhinosinusitis with nasal polyps were reviewed by 7 fellowship-trained rhinologists and scored according to the POPS. Videos were rated again 1 month later by the same reviewers, and scores were assessed for test-retest and inter-rater reliability.

RESULTS

Overall inter-rater reliability for the first and second reviews of the 52 videos was Kf = 0.49 (95% CI 0.42-0.57) and Kf = 0.50 (95% CI 0.42-0.57) for the POPS. Intra-rater reliability showed near-perfect test-retest reliability for the POPS with Kf = 0.80 (95% CI 0.76-0.84).

CONCLUSION

The POPS is an easy-to-use, reliable, and novel objective endoscopic grading scale that more accurately describes polyp recurrence in the postoperative state which will be useful in the future for measuring the efficacy of various medical and surgical interventions.

Association Between Metabolic Syndrome and Outcomes in Complex Head and Neck Surgery

OBJECTIVES

We aim to evaluate the impact of MetS on the short-term postoperative outcomes of complex head and neck surgery patients.

METHODS

This is a retrospective cohort analysis of the 2005 to 2017 National Surgical Quality Improvement Program (NSQIP) database. NSQIP database was queried for 30-day outcomes of patients undergoing complex head and neck surgeries, defined as laryngectomy or mucosal resection followed by free tissue transfer, similar to prior NSQIP studies. Patients with hypertension, diabetes, and body mass index (BMI) >30 kg/m2 were defined as having MetS. Adverse events were defined as experiencing readmission, reoperation, surgical/medical complications, or mortality.

RESULTS

A total of 2764 patients (27.0% female) with a mean age of 62.0 ± 11.7 years were included. Patients with MetS (n = 108, 3.9%) were more likely to be female (P = .017) and have high ASA classification (P = .030). On univariate analysis, patients with MetS were more likely to require reoperation (25.9% vs 16.7%, P = .013) and experience medical complications (26.9% vs 15.4% P = .001) or any adverse events (61.1% vs 48.7%, P = .011) compared to patients without MetS. On multivariate logistic regression after adjusting for age, sex, race, ASA classification, and complex head and neck surgery type, MetS was an independent predictor of medical complications (odds ratio 2.34, 95% CI 1.28-4.27, P = .006).

CONCLUSION

Patients with MetS undergoing complex head and neck surgery are at increased risk of experiencing medical complications. Identifying patients with MetS can therefore aid surgeons in preoperative risk assessment and help improve postoperative management.

Frailty does not worsen postoperative outcomes in sinonasal squamous cell carcinoma

PURPOSE

Sinonasal squamous cell carcinoma (SCC) is an aggressive malignancy frequently requiring surgical resection and adjuvant treatment. Frailty is a metric that attempts to estimate a patient's ability to tolerate the physiologic stress of treatment. There is limited work describing frailty in patients with sinonasal cancer. We sought to determine the impact of frailty on postoperative outcomes in patients undergoing treatment for sinonasal SCC.

MATERIALS AND METHODS

Cases of patients undergoing surgical resection of sinonasal SCC at two tertiary medical centers were queried. Demographic, treatment, and survival data were recorded. Frailty was calculated using validated indexes, including the American Society of Anesthesiologists (ASA) classification, modified 5-item frailty index (mFI-5), and the Charlson Comorbidity Index (CCI). Primary outcomes included medical and surgical complications, readmission, and length of stay (LOS).

RESULTS

38 patients were included. There were 23 (60.5 %) men and 15 (39.5 %) women with an average age of 59.6 ± 12.1 years. MFI-5 was 0.76 ± 0.54 and CCI was 5.71 ± 2.64. No significant association was noted between frailty measures and postoperative outcomes including 30-day medical complications, 30-day surgical complications, any 30-day complication, and readmission. Increased ASA was noted to be predictive of increased length of stay (Incidence Rate Ratio: 1.80, 95 % confidence interval [CI]: 1.16-2.83, p = 0.009).

CONCLUSIONS

We found no association between frailty metrics and worsening surgical or medical postoperative outcomes. This suggests that frailty metrics may not be as relevant for sinonasal surgery even for advanced pathologies, given the more limited physiologic impact of minimally invasive surgery.

A metagenomic analysis of the virome of inverted papilloma and squamous cell carcinoma

INTRODUCTION

Inverted papilloma (IP) is a sinonasal tumor with a well-known potential for malignant transformation. The role of human papillomavirus (HPV) in its pathogenesis has been controversial. The purpose of this study was to determine the virome associated with IP, with progression to carcinoma in situ (CIS), and invasive carcinoma.

METHODS

To determine the HPV-specific types, a metagenomics assay that contains 62,886 probes targeting viral genomes in a microarray format was used. The platform screens DNA and RNA from fixed tissues from eight controls, 16 IP without dysplasia, five IP with CIS, and 13 IP-associated squamous cell carcinoma (IPSCC). Paired with next-generation sequencing, 48 types of HPV with 857 region-specific probes were interrogated against the tumors.

RESULTS

The prevalence of HPV-16 was 14%, 42%, 70%, and 73% in control tissue, IP without dysplasia, IP with CIS, and IPSCC, respectively. The prevalence of HPV-18 had a similar progressive increase in prevalence, with 14%, 27%, 67%, and 74%, respectively. The assay allowed region-specific analysis, which identified the only oncogenic HPV-18 E6 to be statistically significant when compared with control tissue. The prevalence of HPV-18 E6 was 0% in control tissue, 25% in IP without dysplasia, 60% in IP with CIS, and 77% in IPSCC.

CONCLUSIONS

There are over 200 HPV types that infect human epithelial cells, of which only a few are known to be high-risk. Our study demonstrated a trend of increasing prevalence of HPV-18 E6 that correlated with histologic severity, which is novel and supports a potential role for HPV in the pathogenesis of IP.

Preoperative, technical, and postoperative considerations for skull base reconstruction: a practical review of critical concepts

Despite widespread adoption and advances in endoscopic skull base surgery, with expanding indications and the ability to effectively treat larger and more complex pathologies, skull base reconstruction following tumor resection and prevention of cerebrospinal fluid leak remains a challenge for even the most seasoned of surgical teams. Mounting evidence in all areas have pushed our understanding of skull base reconstruction principles forward. In this narrative review, we summarize critical concepts and provide practical but comprehensive guiding principles on preoperative, intraoperative/technical, and postoperative management principles related to optimizing skull base reconstructive success. The goal is to provide an informative resource for skull base surgeons (both otolaryngologists and neurosurgeons) to reference regarding state-of-the-art evidence surrounding this ever-evolving topic.

Diagnosis, Prognosticators, and Management of Acute Invasive Fungal Rhinosinusitis: Multidisciplinary Consensus Statement and Evidence-Based Review with Recommendations

BACKGROUND

Acute invasive fungal sinusitis (AIFS) is an aggressive disease that requires prompt diagnosis and multidisciplinary treatment given its rapid progression. However, there is currently no consensus on diagnosis, prognosis, and management strategies for AIFS, with multiple modalities routinely employed. The purpose of this multi-institutional and multidisciplinary evidence-based review with recommendations (EBRR) is to thoroughly review the literature on AIFS, summarize the existing evidence, and provide recommendations on the management of AIFS.

METHODS

The PubMed, EMBASE, and Cochrane databases were systematically reviewed from inception through January 2022. Studies evaluating management for orbital, non-sinonasal head and neck, and intracranial manifestations of AIFS were included. An iterative review process was utilized in accordance with EBRR guidelines. Levels of evidence and recommendations on management principles for AIFS were generated.

RESULTS

A review and evaluation of published literature was performed on 12 topics surrounding AIFS (signs and symptoms, laboratory and microbiology diagnostics, endoscopy, imaging, pathology, surgery, medical therapy, management of extrasinus extension, reversing immunosuppression, and outcomes and survival). The aggregate quality of evidence was varied across reviewed domains.

CONCLUSION

Based on the currently available evidence, judicious utilization of a combination of history and physical examination, laboratory and histopathologic techniques, and endoscopy provide the cornerstone for accurate diagnosis of AIFS. In addition, AIFS is optimally managed by a multidisciplinary team via a combination of surgery (including resection whenever possible), antifungal therapy, and correcting sources of immunosuppression. Higher quality (i.e., prospective) studies are needed to better define the roles of each modality and determine diagnosis and treatment algorithms.

The rising cost of rhinologic medications

BACKGROUND

The high prescription drug cost in the United States may negatively affect patient prognosis and treatment compliance.

OBJECTIVE

To fill the knowledge gap and inform clinicians regarding rhinology medications price changes by evaluating trends in price changes of highly used nasal sprays and allergy medications.

METHODS

The 2014-2020 Medicaid National Average Drug Acquisition Cost database was queried for drug pricing information for the following classes of medications: intranasal corticosteroids, oral antihistamines, antileukotrienes, intranasal antihistamines, and intranasal anticholinergics. Individual medications were identified by Food and Drug Administration-assigned National Drug Codes. Per unit, drug prices were analyzed for average annual prices, average annual percentage price changes, and inflation-adjusted annual and composite percentage price changes.

RESULTS

Beclometasone (Beconase AQ, 56.7%, QNASL, 77.5%), flunisolide (Nasalide, -14.6%), budesonide (Rhinocort Aqua, -1.2%), fluticasone (Flonase, -6.8%, Xhance, 11.7%), mometasone (Nasonex, 38.2%), ciclesonide (Omnaris, 73.8%), combination azelastine and fluticasone (Dymista, 27.3%), loratadine (Claritin, -20.5%), montelukast (Singulair, 14.5%), azelastine (Astepro, 21.9%), olopatadine (Patanase, 27.3%), and ipratropium bromide (Atrovent, 56.6%) had an overall change in inflation-adjusted per unit cost between 2014 and 2020 (% change). Of 14 drugs evaluated, 10 had an increase in inflation-adjusted prices, for an average increase of 42.06% ± 22.27%; 4 of 14 drugs had a decrease in inflation-adjusted prices, for an average decrease of 10.78% ± 7.36%.

CONCLUSION

The rising cost of highly used medications contributes to increased patient acquisition costs and may pose barriers of drug adherence to particularly vulnerable populations.

Postoperative Obstructive Sleep Apnea Management Following Endoscopic Pituitary Surgery: A Systematic Review

OBJECTIVE

There is currently no consensus on the appropriate timing of noninvasive positive pressure ventilation (PPV) resumption in patients with obstructive sleep apnea (OSA) after endoscopic pituitary surgery. We performed a systematic review of the literature to better assess the safety of early PPV use in OSA patients following surgery.

METHODS

The study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Databases in English were searched using the keywords: "sleep apnea," "CPAP," "endoscopic," "skull base," "transsphenoidal" and "pituitary surgery." Case reports, editorials, reviews, meta-analyses, unpublished and abstract-only articles were all excluded.

RESULTS

Five retrospective studies were identified, comprising 267 patients with OSA who underwent endoscopic endonasal pituitary surgery. The mean age of patients in four studies (n = 198) was 56.3 years (SD = 8.6) and the most common indication for surgery was pituitary adenoma resection. The timing of PPV resumption following surgery was reported in four studies (n = 130), with 29 patients receiving PPV therapy within two weeks. The pooled rate of postoperative cerebrospinal fluid leak associated with PPV resumption was 4.0% (95% CI: 1.3-6.7%) in three studies (n = 27) and there were no reports of pneumocephalus associated with PPV use in the early postoperative period (<2 weeks).

CONCLUSIONS

Early resumption of PPV in OSA patients after endoscopic endonasal pituitary surgery appears relatively safe. However, the current literature is limited. Additional studies with more rigorous outcome reporting are warranted to assess the true safety of re-initiating PPV postoperatively in this population.

Characteristics and Outcomes in Pediatric Versus Adult Craniopharyngiomas: A Systematic Review and Meta-Analysis

BACKGROUND

Craniopharyngiomas account for 1.2% to 4.6% of all intracranial tumors. Although age at presentation is distributed bimodally, with a pediatric peak occurring between 5 and 15 years and an adult peak between 50 and 70 years, presentation, treatment, and outcome differences between these two craniopharyngioma populations have not been thoroughly characterized.

OBJECTIVE

To compare treatments and outcomes between adult and pediatric craniopharyngiomas.

METHODS

This is a systematic review and meta-analysis. Web of Science, MEDLINE, and Scopus databases were searched for primary studies reporting postoperative complications, functional outcomes, recurrence, and overall survival in patients with craniopharyngioma undergoing surgery.

RESULTS

The search yielded 1,202 unique articles, of which 106 (n=4,202 patients) met criteria for qualitative synthesis and 23 (n=735 patients) met criteria for meta-analysis. Compared with adult, pediatric craniopharyngiomas were less likely to present with visual defects (odds ratio [OR] 0.54, 95% CI 0.36-0.80) or cognitive impairment (OR 0.29, 95% CI 0.12-0.71) and more likely with headaches (OR 2.08, 95% CI 1.16-3.73). Children presented with significantly larger tumors compared with adults (standardized mean difference 0.68, 95% CI 0.38-0.97). Comparing functional outcomes, pediatric patients sustained higher rates of permanent diabetes insipidus (OR 1.70, 95% CI 1.13-2.56), obesity (OR 3.15, 95% CI 1.19-8.31), and cranial nerve and/or neurological defects (OR 4.87, 95% CI 1.78-13.31) than adults. No significant differences were found in rates of postoperative cerebrospinal fluid leak, overall or progression-free survival, or recurrence.

CONCLUSION

Adult and pediatric craniopharyngiomas seem to have fundamental differences in clinical presentation and functional outcomes. These patients frequently require multimodality treatment and are best managed with a multidisciplinary team and an individualized approach.

Head and neck solitary fibrous tumors: A review of the National Cancer Database

BACKGROUND

Head and neck solitary fibrous tumors (SFTs) are rare neoplasms, with few large-scale studies describing this entity. We evaluated the demographics and correlates of survival in a large series of SFT patients.

METHODS

The 2004-2017 National Cancer Database was queried for head and neck SFT patients receiving definitive surgery. Cox proportional-hazards and Kaplan-Meier analyses assessed overall survival (OS).

RESULTS

Of 135 patients, sinonasal (33.1%) and orbital (25.9%) SFTs were most common. Approximately 93% of SFTs were invasive and 64% were classified as hemangiopericytomas. The 5-year OS of skull base SFTs (84.5%) was lower than sinonasal (98.7%) and orbital (90.7%) SFTs (all p < 0.05). Government insurance exhibited higher mortality (HR 5.116; p < 0.001) and lower OS (p = 0.001).

CONCLUSION

Head and neck SFTs presented with distinct prognoses based on anatomical origin. Overall survival was particularly worse in patients with skull base SFTs or government insurance. Prognostically, hemangiopericytomas were indistinct from other SFTs.

Clinical manifestations, management, and outcomes of primary silent sinus syndrome: a systematic review

INTRODUCTION

Silent sinus syndrome (SSS) is a rare disorder of the maxillary sinus, which may present with orbital symptoms. Most reports of silent sinus syndrome are limited to small series or case reports. This systematic review comprehensively characterizes the various clinical presentations, management, treatment, and outcomes in patients with SSS.

METHODS

A systematic literature search of the PubMed, Cochrane, Web of Science, and Scopus databases. Inclusion criteria were studies describing the presentation, management, or treatment of SSS or chronic maxillary atelectasis.

RESULTS

One hundred fifty-three articles were included in the final review (n=558 patients). Mean age at diagnosis was 38.8 ± 14.1 years, with a relatively even distribution among sexes. Enophthalmos and/or hypoglobus were the most frequent symptoms, along with diplopia, headache, or facial pressure/pain. Most patients (87%) underwent functional endoscopic sinus surgery (FESS), and 23.5% received orbital floor reconstruction. Post-treatment, patients had significant reductions in enophthalmos (2.67 ± 1.39 vs. 0.33 ± 0.75 mm) and hypoglobus (2.22 ± 1.43 vs. 0.23 ± 0.62 mm). Most patients (83.2%) achieved partial or total resolution of clinical symptoms.

CONCLUSIONS

SSS has a variable clinical presentation, with enophthalmos and hypoglobus being most common. FESS with or without orbital reconstruction are effective treatments to address the underlying pathology and structural deficits.

Development of a Machine Learning Model to Predict Recurrence of Oral Tongue Squamous Cell Carcinoma

Despite diagnostic advancements, the development of reliable prognostic systems for assessing the risk of cancer recurrence still remains a challenge. In this study, we developed a novel framework to generate highly representative machine-learning prediction models for oral tongue squamous cell carcinoma (OTSCC) cancer recurrence. We identified cases of 5- and 10-year OTSCC recurrence from the SEER database. Four classification models were trained using the H₂O ai platform, whose performances were assessed according to their accuracy, recall, precision, and the area under the curve (AUC) of their receiver operating characteristic (ROC) curves. By evaluating Shapley additive explanation contribution plots, feature importance was studied. Of the 130,979 patients studied, 36,042 (27.5%) were female, and the mean (SD) age was 58.2 (13.7) years. The Gradient Boosting Machine model performed the best, achieving 81.8% accuracy and 97.7% precision for 5-year prediction. Moreover, 10-year predictions demonstrated 80.0% accuracy and 94.0% precision. The number of prior tumors, patient age, the site of cancer recurrence, and tumor histology were the most significant predictors. The implementation of our novel SEER framework enabled the successful identification of patients with OTSCC recurrence, with which highly accurate and sensitive prediction models were generated. Thus, we demonstrate our framework's potential for application in various cancers to build generalizable screening tools to predict tumor recurrence.

Impact of esthesioneuroblastoma treatment delays on overall patient survival

OBJECTIVES

To characterize clinical factors associated with esthesioneuroblastoma treatment delays and determine the impact of these delays on overall survival.

STUDY DESIGN

Retrospective database analysis.

METHODS

The 2004-2016 National Cancer Database was queried for patients with esthesioneuroblastoma managed by primary surgery and adjuvant radiation. Durations of diagnosis-to-treatment initiation (DTI), diagnosis-to-treatment end (DTE), surgery-to-RT initiation (SRT), radiotherapy treatment (RTD), and total treatment package (TTP) were analyzed. The cohort was split into two groups for each delay interval using the median time as the threshold.

RESULTS

A total of 814 patients (39.6% female, 88.5% white) with mean ± SD age of 52.6 ± 15.1 years who underwent both esthesioneuroblastoma surgery and adjuvant radiotherapy were queried. Median DTI, DTE, SRT, RTD, and TTP were 34, 140, 55, 45, and 101 days, respectively. A significant association was identified between increased regional radiation dose above 66 Gy and decreased DTI (OR = 0.54, 95% CI 0.35-0.83, p = 0.01) and increased RTD (OR = 3.94, 95% CI 2.36-6.58, p < 0.001) durations. Chemotherapy administration was linked with decreased SRT (OR = 0.64, 95% CI 0.47-0.89, p = 0.01) and TTP (OR = 0.59, 95% CI 0.43-0.82, p = 0.001) durations. Cox proportional-hazards analysis revealed that increased RTD was associated with decreased survival (HR = 1.80, 95% CI 1.26-2.57, p < 0.005), independent of age, sex, race, regional radiation dose, facility volume, facility type, insurance status, modified Kadish stage, chemotherapy status, Charlson-Deyo comorbidity index, and surgical margins.

CONCLUSIONS

Delays during, and prolongation of radiotherapy for esthesioneuroblastoma appears to be associated with decreased survival.

An algorithm for the use of free tissue graft reconstruction in the endoscopic endonasal approach for pituitary tumors

OBJECTIVE

To identify factors associated with successful use of free tissue grafting versus vascularized reconstruction after resection of pituitary tumors.

METHODS

A retrospective chart review of two tertiary academic medical centers over 3.5 years was conducted. Variables assessed included age, sex, body mass index (BMI), pathology, extent of surgical exposure, cavernous sinus or suprasellar extension, intraoperative cerebrospinal fluid (CSF) leak, grade of leak, previous radiation, and prior surgery. Reconstructive techniques were divided into no reconstruction, free tissue grafts, and vascularized flaps.

RESULTS

485 patients were included. Free grafts were used in 299/485 cases (61.6%) and were more commonly used with smaller approaches (p<0.001). Larger exposure size and CSF leak grades 2 and 3 were associated with vascularized flap use (p<0.001 and p=0.012, respectively). Using multivariate regression, type of reconstruction could be predicted by increasing extent of approach, intraoperative CSF leak grade, and suprasellar extension (OR 2.014, p <0.001, 95% CI 1.335-3.039; OR 1.636, p=0.025, 95% CI 1.064-2.517; OR 1.975, p<0.001, 95% CI 1.554-2.510, respectively). Postoperative CSF leak occurred in 9 out of 173 (5.2%) patients with intraoperative leak and was not associated with any factors on analysis.

CONCLUSION

We propose an algorithm whereby grade 1 CSF leaks in sellar and parasellar resections can be successfully reconstructed with a free graft. Vascularized flaps may be reserved for grade 2 or 3 intraoperative CSF leaks, extended approaches, or tumors with suprasellar extension.

Intranasal Anticholinergics for Treatment of Chronic Rhinitis: Systematic Review and Meta-Analysis

OBJECTIVE

Topical intranasal anticholinergics are commonly prescribed for the relief of chronic rhinitis and associated symptoms, warranting thorough assessment of the supporting evidence. The present study aimed to evaluate the safety and efficacy of anticholinergic nasal sprays in the management of allergic and non-allergic rhinitis symptom severity and duration.

METHODS

A search encompassing the Cochrane Library, PubMed/MEDLINE, and Scopus databases was conducted. Primary studies describing rhinorrhea, nasal congestion, and/or postnasal drip outcomes in rhinitis patients treated with an anticholinergic spray were included for review.

RESULTS

The search yielded 1,029 unique abstracts, of which 12 studies (n = 2,024) met inclusion criteria for qualitative synthesis and 9 (n = 1,920) for meta-analysis. Median follow-up was 4 weeks and ipratropium bromide was the most extensively trialed anticholinergic. Compared to placebo, anticholinergic treatment was demonstrated to significantly reduce rhinorrhea severity scores (standardized mean difference [95% CI] = -0.77 [-1.20, -0.35]; -0.43 [-0.72, -0.13]) and duration (-0.62 [-0.95, -0.30]; -0.29 [-0.47, -0.10]) in allergic and non-allergic rhinitis patients respectively. Benefit was less consistent for nasal congestion, postnasal drip, and sneezing symptoms. Reported adverse effects included nasal mucosa dryness or irritation, epistaxis, headaches, and pharyngitis, though comparison to placebo found significantly greater risk for epistaxis only (risk ratio [95% CI] = 2.19 [1.22, 3.93]).

CONCLUSION

Albeit treating other symptoms with less benefit, anticholinergic nasal sprays appear to be safe and efficacious in reducing rhinorrhea severity and duration in both rhinitis etiologies. This evidence supports their continued use in the treatment of rhinitis-associated rhinorrhea.

International consensus statement on allergy and rhinology: Allergic rhinitis - 2023

BACKGROUND

In the 5 years that have passed since the publication of the 2018 International Consensus Statement on Allergy and Rhinology: Allergic Rhinitis (ICAR-Allergic Rhinitis 2018), the literature has expanded substantially. The ICAR-Allergic Rhinitis 2023 update presents 144 individual topics on allergic rhinitis (AR), expanded by over 40 topics from the 2018 document. Originally presented topics from 2018 have also been reviewed and updated. The executive summary highlights key evidence-based findings and recommendation from the full document.

METHODS

ICAR-Allergic Rhinitis 2023 employed established evidence-based review with recommendation (EBRR) methodology to individually evaluate each topic. Stepwise iterative peer review and consensus was performed for each topic. The final document was then collated and includes the results of this work.

RESULTS

ICAR-Allergic Rhinitis 2023 includes 10 major content areas and 144 individual topics related to AR. For a substantial proportion of topics included, an aggregate grade of evidence is presented, which is determined by collating the levels of evidence for each available study identified in the literature. For topics in which a diagnostic or therapeutic intervention is considered, a recommendation summary is presented, which considers the aggregate grade of evidence, benefit, harm, and cost.

CONCLUSION

The ICAR-Allergic Rhinitis 2023 update provides a comprehensive evaluation of AR and the currently available evidence. It is this evidence that contributes to our current knowledge base and recommendations for patient evaluation and treatment.

Outcomes and Trends of Treatments in High-Risk Differentiated Thyroid Cancer

OBJECTIVES

To analyze the variant-specific survival benefits and usage patterns of standardized treatment combinations of surgery (S), radioactive iodine ablation (RAI), and thyroid-stimulating hormone suppression therapy (THST) for high-risk differentiated thyroid cancer.

STUDY DESIGN

Retrospective cohort study.

SETTING

National Cancer Database.

METHODS

The 2004-2017 National Cancer Database was queried for patients receiving definitive surgery for high-risk papillary, follicular, or Hurthle cell thyroid cancer. Cox proportional hazards and Kaplan-Meier analyses assessed for treatment-associated survival.

RESULTS

Of 21,076 cases, 18,214 underwent survival analysis with a mean ± SD age of 50.6 ± 17.1 years (71.3% female). When compared with surgery alone, S + RAI was associated with reduced mortality in papillary (hazard ratio [HR], 0.574; P < .001) and follicular (HR, 0.489; P = .004) thyroid cancer. S + RAI + THST was associated with reduced mortality in papillary (HR, 0.514; P < .001), follicular (HR, 0.602; P = .016), and Hurthle cell (HR, 0.504; P = .021) thyroid cancer. In papillary thyroid cancer, S + RAI (91.3%), S + THST (89.2%), and S + RAI + THST (92.7%) were associated with higher 5-year overall survival rates than surgery (85.4%, all P < .001). Papillary thyroid cancer treatments involving THST were associated with higher 5-year overall survival rates than corresponding regimens without THST (all P < .001). In follicular thyroid cancer, S + RAI (73.9%) and S + RAI + THST (78.7%) were associated with higher 5-year overall survival rates than surgery (65.6%, all P < .05). In Hurthle cell thyroid cancer, S + RAI (66.5%) and S + RAI + THST (73.4%) were associated with higher 5-year overall survival rates than surgery (53.7%, all P < .05). On linear regression, THST usage increased by 77.5% (R² = 0.944, P < .001), while RAI usage declined by 11.3% (R² = 0.320, P = .035).

CONCLUSIONS

High-risk differentiated thyroid cancer exhibited varying susceptibilities to different treatment combinations depending on histology, with greatest responses to regimens that included RAI. Physician practices have trended toward decreased RAI and increased THST usage.

Spontaneous skull base cerebrospinal fluid leak during pregnancy: a case report and review of the literature

BACKGROUND

Idiopathic intracranial hypertension can lead to dural defects and spontaneous leakage of cerebrospinal fluid (CSF) from the skull base. Skull base CSF leaks are rarely reported in pregnancy but pose unique challenges for obstetricians and anesthesiologists.

CASE PRESENTATION

A 31-year-old G4P1021 at 14 weeks developed debilitating headaches and CSF rhinorrhea. Brain imaging revealed a bony defect of the sphenoid sinus with a meningoencephalocele and a partially empty sella, consistent with CSF leakage from a skull base defect. The patient was neurologically stable without signs of meningitis; thus, management was focused on symptomatic alleviation. A planned cesarean section was performed at 38 weeks under spinal anesthesia. The patient had spontaneous marked improvement of her symptoms postpartum.

CONCLUSION

Pregnancy may exacerbate skull base CSF leaks, requiring careful management with a multidisciplinary team. Neuraxial anesthesia can safely be performed in pregnant individuals with spontaneous skull base CSF leakage, but further studies are needed to determine the safest mode of delivery in these patients.

Medicare Utilization and Reimbursement Variation Between Rural and Urban Otolaryngologists

OBJECTIVE

To compare billing practices, reimbursement rates, and patient populations of otolaryngology (ORL) physicians practicing in rural and urban settings.

STUDY DESIGN

Retrospective cross-sectional study.

SETTING

Medicare Provider Utilization and Payment Data: Physician and Other Supplier Data.

METHODS

Medicare-allowed payments, number of services, and number of patients were gathered along with patient population comorbidity statistics, including average hierarchical condition category risk scores.

RESULTS

In 2019, 92% of the overall total 8959 ORL physicians practiced in an urban setting. These 8243 urban ORL physicians, on average, billed for 51 (interquartile range [IQR], 31-67) unique Healthcare Common Procedure Coding System (HCPCS) codes, cared for 393 (IQR, 172-535) Medicare patients, performed 1761 (IQR, 502-2070) services, and collected $139,957 (IQR, $55,527-$178,479) per provider. In contrast, the 704 rural ORL physicians, on average, billed for a greater number of unique HCPCS codes (59; IQR, 37-77; P < .001), treated more Medicare patients (445; IQR, 242-614; P < .001), and performed more services (2330; IQR, 694-2748; P < .001) but collected about the same per provider ($141,035; IQR, $56,555-$172,864; P = .426). Older age was associated with rural practice (P = .027). Among both urban and rural ORL physicians, the variety and complexity of procedures and patient comorbidity profiles were comparable.

CONCLUSION

Most ORL physicians practice in large urban settings, a finding potentially related to financial sustainability and career opportunity. With an already small workforce, the aging rural ORL physician population is an identifiable weak point in the otolaryngology specialty that must be addressed with geo-specific recruitment campaigns, rural work incentivization, and the development of career advancement opportunities in rural areas.

Resection of an oropharyngeal venous malformation

BACKGROUND

Venous malformations (VMs) are congenital vascular lesions caused by enlarged and ectatic venous channels. Current methods of treatment for VMs involve a combination of sclerotherapy, laser therapy, and surgical resection. While sclerotherapy remains the most commonly used treatment for small VMs, surgery remains an important tool for isolated VMs or larger VMs with higher flow due to potential local and systemic side effects associated with the use of certain sclerosing agents.

METHODS/RESULTS

Here we present a case of a patient with a naso- and oropharyngeal venous malformation which was successfully resected with endoscopic-assisted transoral surgery.

CONCLUSIONS

This is a low-fingerprint technique to tumors of the oropharynx with excellent visualization and maneuverability in cases where TORS is not an option. This technique does not require palate splitting or excessive retraction, allows multiple surgeons to work simultaneously, and is associated with significantly lower morbidity than transcervical techniques.

Stage-Specific Survival in Young Patients With Oral Tongue Squamous Cell Carcinoma

OBJECTIVE

To determine demographic factors and clinicopathologic characteristics associated with survival in young patients (age <45 years) with early- (I-II) or late-stage (III-IV) oral tongue squamous cell carcinoma (OTSCC).

STUDY DESIGN

Retrospective database review.

SETTING

National Cancer Database.

METHODS

A retrospective review of 3262 OTSCC cases in young patients between 2005 and 2014 was performed by using data from the National Cancer Database. Factors affecting 2-year survival in patients with early- and late-stage disease were evaluated via univariate and multivariate analyses.

RESULTS

Overall, 1899 patients with early-stage OTSCC and 1363 with late-stage OTSCC were analyzed. In multivariate analysis of early-stage OTSCC, high tumor grade (hazard ratio, 2.08 [95% CI, 1.45-2.99]), local metastasis (2.85 [1.37-5.95]), and tumor size (1.04 [1.02-1.07]) were predictors of mortality. In late-stage OTSCC, African American race (2.79 [1.40-5.56]), positive surgical margins (1.77 [1.07-2.93]), local metastasis (2.20 [1.03-4.72]), distant metastasis (11.66 [2.10-64.73]), depth of invasion (1.03 [1.01-1.05]), and tumor size (1.01 [1.003-1.01]) were predictors of mortality. Subset analysis of clinical N0-stage tumors revealed that treatment with surgery alone was associated with improved survival (P < .001).

CONCLUSION

Positive lymph nodes, high tumor grade, and larger tumor size were associated with increased mortality risk in early- and late-stage young OTSCC. More aggressive up-front treatment, including extirpative surgery and elective neck dissection, may be associated with improved outcomes and should be considered in early-stage cases with high-risk features.
