How Do Patients and Otolaryngologists Define Dizziness?

OBJECTIVE

To assess for differences in how patients and otolaryngologists define the term dizziness.

METHODS

Between June 2020 and December 2022, otolaryngology clinicians and consecutive patients at 5 academic otolaryngology institutions across the United States were asked to define the term "dizziness" by completing a semantics-based questionnaire containing 20 common descriptors of the term within 5 symptom domains (imbalance-related, lightheadedness-related, motion-related, vision-related, and pain-related). The primary outcome was differences between patient and clinician perceptions of dizzy-related symptoms. Secondary outcomes included differences among patient populations by geographic location.

RESULTS

Responses were obtained from 271 patients and 31 otolaryngologists. Patients and otolaryngologists selected 7.7 ± 3.5 and 7.1 ± 4.3 symptoms, respectively. Most patients (266, 98.2%) selected from more than 1 domain and 17 (6.3%) patients identified symptoms from all 5 domains. Patients and clinicians were equally likely to define dizziness using terms from the imbalance (difference, -2.3%; 95% CI, -13.2%, 8.6%), lightheadedness (-14.1%; -29.2%, 1.0%), and motion-related (9.4; -0.3, 19.1) domains. Patients were more likely to include terms from the vision-related (23.6%; 10.5, 36.8) and pain-related (18.2%; 10.3%, 26.1%) domains. There were minor variations in how patients defined dizziness based on geographic location.

CONCLUSIONS

Patients and otolaryngologists commonly described dizziness using symptoms related to imbalance, lightheadedness, and motion. Patients were more likely to use vision or pain-related terms. Understanding of these semantic differences may enable more effective patient-clinician communication.

Are you congested? A comparison of definitions between otolaryngologists and their patients

OBJECTIVE

To assess for differences of intended meaning in the description of congestion-related symptoms among otolaryngology patients and clinicians.

MATERIALS AND METHODS

Between June 2020 and October 2022, a questionnaire consisting of 16 common descriptors of congestion-related symptoms within four domains (obstructive-related, pressure-related, mucus-related, and other symptoms) was completed by patients and otolaryngologists at five tertiary otolaryngology practices. The primary outcome was to assess differences in patient and clinician perceptions of congestion-related symptoms. Differences based on geographic location was a secondary outcome.

RESULTS

A total of 349 patients and 40 otolaryngologists participated. Patients selected a median of 6.8 (standard deviation [SD] 3.0) terms compared with 4.0 (SD 1.6) terms for otolaryngologists (p < 0.001). Otolaryngologists were more likely to select obstruction-related symptoms (difference 6.3%; 95% confidence interval [CI] 3.8%, 8.9%). Patients were more likely to describe congestion using pressure-related (-43.7%; -58.9%, -28.5%), mucus-related (-43.5%; -59.3%, -27.8%), and other symptoms (-44.2; -51.3%, -37.1%) compared with otolaryngologists. There were no significant differences identified based on geographic location with regard to symptom domains on multivariate analysis.

CONCLUSIONS

There are differences between otolaryngologists and their patients in the interpretation of the symptoms of congestion. Clinicians tended to have a narrower interpretation of congestion that was limited to the obstruction-related symptom domain, while patients defined congestion more broadly. This has important counseling and communication implications for the clinician.

Layperson Perception of Reflux-Related Symptoms

Objective

To assess for differences of intended meaning in the description of reflux-related symptoms among otolaryngology patients and clinicians.

Study Design

Cross-sectional survey-based study.

Setting

Five tertiary, academic otolaryngology practices.

Methods

Between June 2020 and July 2022, a questionnaire consisting of 20 common descriptors of reflux-related symptoms within four domains (throat-, chest-, stomach-, and sensory-related symptoms) was completed by patients. Attending otolaryngologists at five academic medical centers then completed the same survey. The primary outcome was to assess differences in patient and clinician perceptions of reflux-related symptoms. Differences based on geographic location was a secondary outcome.

Results

A total of 324 patients and 27 otolaryngologists participated. Patients selected a median of six terms compared with 10.5 for otolaryngologists (p < .001). Otolaryngologists were more likely to select sensory symptoms (difference: 35.8%; 95% confidence interval [CI]: 19.2%, 52.4%), throat-related symptoms (32.4%; 21.2, 43.6%), and chest-related symptoms (12.4%; 8.8, 15.9). Otolaryngologists and patients were equally likely to consider stomach symptoms as related to reflux (4.0%, -3.7%, 11.7%). No significant differences were identified based on geographic location.

Conclusion

There are differences between otolaryngologists and their patients in the interpretation of the symptoms of reflux. Patients tended to have a narrower interpretation of reflux with symptoms primarily limited to classic stomach-related symptoms, while clinicians tended to have a broader definition of reflux that included extra-esophageal manifestations of disease. This has important counseling implications for the clinician, as patients presenting with reflux symptoms may not comprehend the relationship of those symptoms to reflux disease.

High Grade Ectopic Pituitary Adenoma within the Cerebellopontine Angle: A Case Report

Ectopic pituitary tumors are neoplasms with no connection to the pituitary gland and are commonly deposited in other areas of the anterior skull base. A 32-year-old female presented with a three-month history of right sided facial weakness, sensorineural hearing loss, diplopia, and severe headaches. Physical examination revealed a mid-dilated sluggishly reactive right pupil with slight limitation in all gazes, as well as right-sided orbicularis weakness, lagophthalmos, and decreased facial sensation. An MRI of the head without contrast revealed a 3.7 x 1.8 x 2.6 cm mildly enhancing mass in the right internal acoustic meatus and along the petrous ridge. The case was brought before the institution’s tumor board, where concern for higher grade pathology, such as hemangiopericytoma, was discussed. Per patient preference, surgical biopsy of the tumor was performed. Immunohistochemical staining revealed a WHO grade II neuroendocrine tumor, with cells staining positive for synaptophysin, chromogranin, and CD56, with a Ki-67 index of 8%. In addition to the ectopic location, this pituitary tumor was noted to be aggressive in nature based on its high Ki-67 index. Surgical excision or radiologic therapy of tumors involving the CPA are appropriate treatments in most cases.

Layperson Perception of Symptoms Caused by the Sinuses

OBJECTIVE

To assess the perceived symptoms caused by the sinuses as defined by otolaryngology patients and clinicians.

STUDY DESIGN

Multi-institutional cross-sectional study.

SETTING

Six academic outpatient otolaryngology practices.

METHODS

We performed a multi-institutional, cross-sectional study using a semantics-based questionnaire. Consecutive patients were enrolled at 6 academic otolaryngology centers from June 2020 to May 2021. The primary outcome examined patient and provider definitions for the symptoms caused by the sinuses from a list of 28 proposed terms covering 6 general categories. These data were also collected from otolaryngology faculty at the same institutions.

RESULTS

Responses were obtained from 451 patients (54% female, mean age 48.3 years) and 29 otolaryngologists (38% female, mean age 37.4 years). Patients selected a median of 12 terms, compared to 8.5 for otolaryngologists. Among patients, the most frequently selected symptom domains were mucus (419, 92.9%), airflow (412, 91.4%), and pain (389, 86.3%). Compared to clinicians, patients more frequently selected symptoms related to the ear (difference, 48.3%; 95% confidence interval [CI], 34.8%-59.3%), throat (difference, 35.7%, 95% CI, 22.0%-47.5%), systemic (difference, 34.4%, 95% CI, 21.2%-46.0%), mucus (difference, 20.5%, 95% CI, 10.2%-30.6%), and airflow domains (difference, 19.0%, 95% CI, 8.4%-29.3%). Multiple domains were selected by 98% of patients and 79% of providers.

CONCLUSION

Semantic differences exist between patients and clinicians regarding the symptoms caused by the sinus with patients having a broader range of perceived symptoms. These differences may provide clues to improve communication between otolaryngologists and their patients.

What do we mean when we have a "sinus infection?"

INTRODUCTION

Sinus infections are a common reason patients seek medical care. However, the intended meaning of the term sinus infection among patients and otolaryngologists is incompletely understood.

METHODS

In this multi-institutional cross-sectional study, a semantics-based questionnaire was provided to consecutive patients presenting to otolaryngology clinics at six academic centers from June 2020 until May 2021. The primary outcome was respondent definitions for sinus infection from a list of 28 proposed terms covering six general categories. Secondary outcome measures included differences between geographic regions.

RESULTS

Responses were obtained from 560 patients (54% female, mean age 48.9 years) and 29 otolaryngologists (42% female, mean age 37.4 years). Patients and otolaryngologists selected a median of 10 and 11 terms, respectively, to define a sinus infection. Among patients the most frequently selected symptom categories were mucus (500, 89.3%), pressure/pain (480, 85.7%), and airflow (468, 83.6%). Compared to patients, clinicians selected with greater frequency the symptom categories of pressure/pain (14.3% difference; 95% CI, 7.6% to 22.5%), mucus (10.7% difference; 95% CI, 4.7% to 18.3%) and airflow (13.0% difference; 95% CI, 4.8% to 21.7%). Multiple categories were selected by 96% of patients and 100% of providers.

CONCLUSION

The definition of sinus infection appears variable for both patients and otolaryngologists, though patients appear to apply a broader range of symptoms to the term sinus infection. There were no pronounced geographic differences in the description of a sinus infection in this US sample population. Patients commonly described sinus infection in the context of pain-related symptoms. Appreciation of these semantic differences may enable more effective patient-clinician communication.

Antibiotic Use in Lateral Skull Base Surgery: A Survey of the North American Skull Base Society

Objectives Antibiotic use in lateral skull base surgery (LSBS) has not been thoroughly investigated in the literature. There is wide variability in antibiotic use and insufficient data to guide management. This study aims to describe the factors and patterns influencing antibiotic use in LSBS among the membership of the North American Skull Base Society (NASBS).

Design An online-based survey was designed and distributed to the membership of the NASBS. Data was analyzed using bivariate analysis and logistic regression modeling.

Setting Online-based questionnaire.

Participants NASBS membership.

Main Outcome Measures Use of intraoperative antibiotics and use of postoperative antibiotics.

Results The survey response rate was 26% (208 respondents). Of the 208 total respondents, 143 (69%) respondents performed LSBS. Most respondents are neurosurgeons (69%) with the remaining being otolaryngologists (31%). The majority of respondents (79%) are fellowship-trained in skull base surgery. Academic or government physicians make up 69% of respondents and 31% are in private practice with or without academic affiliations. Bivariate analysis showed that practice setting significantly influenced intraoperative antibiotic use (p = 0.01). Geographic location significantly affected postoperative antibiotic use (p = 0.01). Postoperative antibiotic duration was significantly affected by presence of chronic otitis media, cerebrospinal fluid leak, and surgeon training (p = 0.02, p = 0.01, and p = 0.006, respectively). Logistic regression modeling showed that the motivation to reduce infection significantly impacted postoperative antibiotic use (p = 0.03).

Conclusion This study demonstrates significant variations in intraoperative and postoperative antibiotic use in LSBS among the NASBS membership. Appropriate guidelines for optimal perioperative antibiotic use patterns should be determined with randomized studies in the future.

Postoperative Infection Rate and Associated Factors Following Endoscopic Sinus Surgery

OBJECTIVES

There is a paucity of data on postoperative infections after endoscopic sinus surgery and associated risk factors. Our objective was to evaluate a cohort of patients undergoing endoscopic sinus surgery (ESS) for chronic rhinosinusitis to determine which perioperative factors may be associated with infection in the 30-day postoperative period.

METHODS

A retrospective cohort study of adults who underwent ESS at a tertiary academic medical center from 2015 to 2018 was performed. The primary outcome was incidence of postoperative infection, defined by identification of sinus purulence on nasal endoscopy necessitating antibiotics within 30 days of surgery. Independent variables collated included the result of postoperative cultures and use of perioperative antibiotics, oral corticosteroids, packing, and steroid-eluting stents. Statistical analysis involved bivariate analysis to identify variables that correlated with postoperative infection and subsequent multivariate logistic regression to identify independent risk factors.

RESULTS

Three hundred seventy-eight unique ESS cases performed in 356 patients were reviewed. The mean age was 46 years (range, 18-87). The most common indication for surgery was chronic rhinosinusitis without nasal polyposis. The postoperative infection rate was 10.1%. The most commonly cultured pathogen was Staphylococcus aureus. Multivariate logistic regression analysis showed that postoperative systemic corticosteroid use was the only risk factor independently associated with infection (OR 3.47 [95% CI 1.23-9.76], P = .018).

CONCLUSION

The incidence of postoperative infection following ESS was 10.1%. The use of postoperative systemic corticosteroids independently increased the risk of infection by 3.47-fold.

Patient Satisfaction and Efficiency Benefits of a Novel Multidisciplinary Rhinology and Allergy Clinic

BACKGROUND

Chronic rhinosinusitis (CRS) is a chronic inflammatory disease of the sinonasal mucosa and with strong associations to other immune-mediated comorbidities. Patients often require referral to both an otolaryngologist and an allergist/immunologist. This study is the first in the literature to describe a multidisciplinary clinic that offers patient care by subspecialists in rhinology and in allergy/immunology.

METHODS

One hundred twenty-nine patients were seen in the Comprehensive Sinus and Allergy Clinic (CSAC) between January 2016 and June 2017 and 43 selected patients were seen in both the standalone allergy and rhinology clinics over the same time period. Patient satisfaction was retrospectively assessed using a modified Press-Ganey satisfaction survey. Time to evaluation and time to follow up appointment were compared between the CSAC and both the standalone rhinology and allergy/immunology clinics.

RESULTS

Patients seen in the CSAC reported high satisfaction with the amount of time spent with the physicians (98.3%), quality of medical care (9.3 ± 1.0), and most importantly, the convenience of seeing two physicians in one day (9.5 ± 1.2). Time from referral placement to clinic evaluation (P ≤ .02) and time to follow up appointment (P ≤ .002) was significantly shorter for the CSAC than for the standalone Rhinology or Allergy clinics.

CONCLUSION

Patients reported high satisfaction with the medical care provided and were also seen much faster in our multidisciplinary clinic as compared to standalone rhinology or allergy/immunology clinics. Overall, a multidisciplinary approach may be beneficial to patients presenting to tertiary referral centers with CRS and atopic conditions.

Sinus Surgery Is Associated with a Decrease in Aspirin-Induced Reaction Severity in Patients with Aspirin Exacerbated Respiratory Disease

BACKGROUND

Nasal polyps influence the burden of aspirin-exacerbated respiratory disease (AERD) by contributing to eicosanoid production. AERD is diagnosed through graded aspirin challenges. It is not known how sinus surgery affects aspirin challenge outcomes.

OBJECTIVE

To investigate the effects of endoscopic sinus surgery (ESS) on aspirin-induced reaction severity and on the levels of eicosanoids associated with these reactions.

METHODS

Twenty-eight patients with AERD were challenged with aspirin before and 3 to 4 weeks after ESS. Respiratory parameters and plasma and urine levels of eicosanoids were compared before and after challenges.

RESULTS

Before ESS, AERD diagnosis was confirmed in all study patients by aspirin challenges that resulted in hypersensitivity reactions. After ESS, reactions to aspirin were less severe in all patients and 12 of 28 patients (43%, P < .001) had no detectable reaction. A lack of clinical reaction to aspirin was associated with lower peripheral blood eosinophilia (0.1 K/μL [interquartile range (IQR) 0.1-0.3] vs 0.4 K/μL [IQR 0.2-0.8]; P = .006), lower urinary leukotriene E₄ levels after aspirin challenge (98 pg/mg creatinine [IQR 61-239] vs 459 pg/mg creatinine [IQR 141-1344]; P = .02), and lower plasma prostaglandin D₂ to prostaglandin E₂ ratio (0 [±0] vs 0.43 [±0.2]; P = .03), compared with those who reacted.

CONCLUSIONS

Sinus surgery results in decreased aspirin sensitivity and a decrease in several plasma and urine eicosanoid levels in patients with AERD. Diagnostic aspirin challenges should be offered to patients with suspected AERD before ESS to increase diagnostic accuracy. Patients with established AERD could undergo aspirin desensitizations after ESS as the severity of their aspirin-induced hypersensitivity reactions lessens.

Novel use of video glasses during binocular microscopy in the otolaryngology clinic

INTRODUCTION

The development of portable, high resolution video displays such as video glasses allows clinicians the opportunity to offer patients an increased ability to visualize aspects of their physical examination in an ergonomic and cost-effective manner. The objective of this pilot study is to trial the use of video glasses for patients undergoing binocular microscopy as well as to better understand some of the potential benefits of the enhanced display option.

METHODS

This study was comprised of a single treatment group. Patients seen in the otolaryngology clinic who required binocular microscopy for diagnosis and treatment were recruited. All patients wore video glasses during their otoscopic examination. An additional cohort of patients who required binocular microscopy were also recruited, but did not use the video glasses during their examination. Patients subsequently completed a 10-point Likert scale survey that assessed their comfort, anxiety, and satisfaction with the examination as well as their general understanding of their otologic condition.

RESULTS

A total of 29 patients who used the video glasses were recruited, including those with normal examinations, cerumen impaction, or chronic ear disease. Based on the survey results, patients reported a high level of satisfaction and comfort during their exam with video glasses. Patients who used the video glasses did not exhibit any increased anxiety with their examination. Patients reported that video glasses improved their understanding and they expressed a desire to wear the glasses again during repeat exams.

CONCLUSION

This pilot study demonstrates that video glasses may represent a viable alternative display option in the otolaryngology clinic. The results show that the use of video glasses is associated with high patient comfort and satisfaction during binocular microscopy. Further investigation is warranted to determine the potential for this display option in other facets of patient care as well as in expanding patient understanding of disease and anatomy.

Antibiotic use patterns in endoscopic sinus surgery: a survey of the American Rhinologic Society membership

BACKGROUND

There is a paucity of data supporting antibiotic use in endoscopic sinus surgery (ESS). The objective of this study is to determine perioperative antibiotic use patterns and factors which influence use in ESS.

METHODS

An online-based survey was distributed to members of the American Rhinologic Society (ARS). Outcomes included timing of perioperative antibiotic use, practice environment, years of experience, and patient factors that influenced antibiotic use.

RESULTS

There were 204 responses (response rate 18.3%); 36.8% of respondents were in academic positions, 32.8% were in private practice, and 30.4% were in academic-affiliated private practice; 20.6% routinely gave preoperative antibiotics, most commonly to reduce bacterial burden (59.5%) and mucosal inflammation (59.5%); 54.4% routinely gave intraoperative antibiotics, most commonly to reduce the risk of postoperative infection (63.1%); 62.3% routinely gave postoperative antibiotics, citing the need to reduce the risk of postoperative infection (75.6%). Diagnosis influenced postoperative antibiotic use in 63.0%. Preoperative antibiotics were more likely to be prescribed by respondents with more than 5 years of experience (odds ratio [OR] 2.97; 95% confidence interval [CI], 1.04 to 8.54; p = 0.043). Compared to private practitioners, academicians were more likely to give intraoperative antibiotics (OR 2.68; 95% CI, 1.39 to 5.17; p = 0.003), but not preoperative or postoperative antibiotics. Use of nonabsorbable packing was significantly associated with use of postoperative antibiotics (OR 2.01; 95% CI, 1.07 to 3.77; p = 0.031).

CONCLUSION

This study demonstrates the significant variation in perioperative antibiotic use among otolaryngologists. These results provide support for the establishment of evidence-based practice guidelines for perioperative antibiotic use in ESS.

Endoscopic modified Lothrop procedure after failure of primary endoscopic sinus surgery: a meta-analysis

BACKGROUND

The endoscopic modified Lothrop procedure (EMLP) has been used as a salvage technique for frontal sinusitis following failed endoscopic sinus surgery (ESS). We aim to examine the safety and efficacy of the EMLP following failure of primary ESS.

METHODS

All English-language publications from 2000 to 2016 reporting the use of EMLP after primary ESS were identified using the PubMed database and evaluated per Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Random effects summaries of patient demographics, comorbidities, and surgical outcomes were obtained through meta-analysis.

RESULTS

Eleven studies constituting 778 patients were included and 86.5% had chronic rhinosinusitis (CRS). Mean follow-up duration was 28.4 months. The mean number of surgeries prior to EMLP was 3.5. Symptom improvement was reported in 82.3%. Subgroup analysis of 7 studies in which all 357 patients had CRS revealed a mean follow-up of 31.5 months. Symptom improvement occurred in 75.9% of cases and 23.1% experienced polyp recurrence. The cerebrospinal fluid leak rate was 2.5%. Restenosis of the neo-ostium occurred in 17.1% with complete closure occurring in 3.9% of cases. The reoperation rate after EMLP was 9.0%. Aspirin sensitivity was associated with an increased risk of cerebrospinal fluid (CSF) leak (p = 0.0339) and a reduced incidence of neo-ostium closure (p = 0.0001). Aspirin sensitivity and asthma were associated with a reduced incidence of reoperation (p ≤ 0.001) and increased symptom improvement (p < 0.005). Restenosis or closure of the frontal neo-ostium was associated with less symptom improvement (p < 0.04) but not with reoperation.

CONCLUSION

The EMLP is an effective salvage procedure for refractory frontal sinusitis based on data from higher-volume centers.

Considerations in incorporating office-based ultrasound of the head and neck

OBJECTIVE: The purpose of this study was to determine the cost considerations and strategies for incorporating ultrasound (US) in a head and neck practice.

STUDY DESIGN AND SETTING: A retrospective chart review of office-based US procedures from 2001 to 2005 was completed at our academic medical center. Billing and coding for US and US guided fine needle aspiration (USFNA) were examined.

RESULTS: The appropriate CPT codes are 76536 for US and 76942 and 10022 for USFNA-related procedures. The USFNA codes should be used repeatedly for correct coding of biopsies from multiple sites. Cost (equipment) sharing between specialties is a potential strategy for office-based US incorporation.

CONCLUSION: Based on practice volume, specific CPT coding, and Medicare reimbursements, office-based US equipment and certification costs could be offset in 1 year.

SIGNIFICANCE: Office-based US can be readily incorporated with significant benefits to patients. Billing and usage strategies were identified that would improve the economics of providing office-based US.

Biofilms in chronic rhinosinusitis: Pathophysiology and therapeutic strategies

Background

There is increasing evidence that biofilms are critical to the pathophysiology of chronic infections including chronic rhinosinusitis (CRS). Until relatively recently, our understanding of biofilms was limited. Recent advances in methods for biofilm identification and molecular biology have offered new insights into the role of biofilms in CRS. With these insights, investigators have begun to investigate novel therapeutic strategies that may disrupt or eradicate biofilms in CRS.

Objective

This review seeks to explore the evidence implicating biofilms in CRS, discuss potential anti-biofilm therapeutic strategies, and suggest future directions for research.

Results

The existing evidence strongly supports the role of biofilms in the pathogenesis of CRS. Several anti-biofilm therapies have been investigated for use in CRS and these are at variable stages of development. Generally, these strategies: 1) neutralize biofilm microbes; 2) disperse existing biofilms; or 3) disrupt quorum sensing. Several of the most promising anti-biofilm therapeutic strategies are reviewed.

Conclusions

A better understanding of biofilm function and their contribution to the CRS disease process will be pivotal to the development of novel treatments that may augment and, potentially, redefine the CRS treatment paradigm. There is tremendous potential for future research.
