Abstract
OBJECTIVE To present the design and methodology for an actively enrolling comparative effectiveness study of revision palatoplasty versus pharyngoplasty for the treatment of velopharyngeal insufficiency (VPI). DESIGN Prospective observational multicenter study. SETTING Twelve hospitals across the United States and Canada. PARTICIPANTS Individuals who are 3-23 years of age with a history of repaired cleft palate and a diagnosis of VPI, with a total enrollment target of 528 participants. INTERVENTIONS Revision palatoplasty and pharyngoplasty (either pharyngeal flap or sphincter pharyngoplasty), as selected for each participant by their treatment team. MAIN OUTCOME MEASURE(S) The primary outcome is resolution of hypernasality, defined as the absence of consistent hypernasality as determined by blinded perceptual assessment of a standard speech sample recorded twelve months after surgery. The secondary outcome is incidence of new onset obstructive sleep apnea. Statistical analyses will use propensity score matching to control for demographics, medical history, preoperative severity of hypernasality, and preoperative imaging findings. RESULTS Study recruitment began February 2021. As of September 2022, 148 participants are enrolled, and 78 have undergone VPI surgery. Enrollment is projected to continue into 2025. Collection of postoperative evaluations should be completed by the end of 2026, with dissemination of results soon thereafter. CONCLUSIONS Patients with VPI following cleft palate repair are being actively enrolled at sites across the US and Canada into a prospective observational study evaluating surgical outcomes. This study will be the largest and most comprehensive study of VPI surgery outcomes to date.

Abstract
Objectives Single-use rhinolaryngoscopes were brought to market in 2019 as an alternative to traditional reusable scopes and have garnered interest across settings given portability and potential cost advantages. While single-use was previously evaluated compared to traditional devices, the overall impact to the consult experience for both users and patients has not been captured. Methods Eighteen residents performed consults with both single-use and reusable rhinolaryngoscope systems on alternating weeks. A five-question cumulative survey administered across three assessment points over a 12-week period using a five-point rating system to rate favorability. Residents and patients also completed four-point scale surveys following procedure(s) to capture the consult experience. Statistical analyses were performed to measure significance differences between survey responses between the two systems. Results Single-use rhinolaryngoscopes received higher overall ratings compared with reusables across each metric captured including overall consult time (4.3 vs. 2.2, p < .001), multiscope consults (4.4 vs. 3.1, p < .001), patient communication (4.6 vs. 2.1, p < .001), teaching opportunities (4.6 vs. 2.1, p < .001), and overall ease of use (4.7 vs. 2.6, p < .001). Residents rated single-use higher than reusable after each procedure in terms of ease of use (1.07 vs. 2.68, p < .001) and visual clarity (1.27 vs. 1.89, p = .003), while patients rated single-use higher for understanding of illness (3.9 vs. 3.1, p < .001) and understanding of treatment rationale (3.9 vs. 3.1, p < .001). Conclusion Resident and patient experience feedback favored single-use rhinolaryngoscopes compared to reusable scope technology across multiple surveyed measurables. Single-use rhinolaryngoscopes provide a viable tool for otorhinolaryngologist and other clinicians to perform rhinolaryngoscopy consults. Level of Evidence 4.

Abstract
OBJECTIVE To construct and validate a deep convolutional neural network (DCNN)-based artificial intelligence (AI) system for the detection of nasopharyngeal carcinoma (NPC) using archived nasopharyngoscopic images. METHODS We retrospectively collected 14107 nasopharyngoscopic images (7108 NPCs and 6999 noncancers) to construct a DCNN model and prepared a validation dataset containing 3501 images (1744 NPCs and 1757 noncancers) from a single center between January 2009 and December 2020. The DCNN model was established using the You Only Look Once (YOLOv5) architecture. Four otolaryngologists were asked to review the images of the validation set to benchmark the DCNN model performance. RESULTS The DCNN model analyzed the 3501 images in 69.35 s. For the validation dataset, the precision, recall, accuracy, and F1 score of the DCNN model in the detection of NPCs on white light imaging (WLI) and narrow band imaging (NBI) were 0.845 ± 0.038, 0.942 ± 0.021, 0.920 ± 0.024, and 0.890 ± 0.045, and 0.895 ± 0.045, 0.941 ± 0.018, and 0.975 ± 0.013, 0.918 ± 0.036, respectively. The diagnostic outcome of the DCNN model on WLI and NBI images was significantly higher than that of two junior otolaryngologists (p < 0.05). CONCLUSION The DCNN model showed better diagnostic outcomes for NPCs than those of junior otolaryngologists. Therefore, it could assist them in improving their diagnostic level and reducing missed diagnoses. LEVEL OF EVIDENCE 3 Laryngoscope, 134:127-135, 2024.

Abstract
Actinomycosis is a progressive granulomatous infection caused by the bacteria Actinomyces israelii. Classically, the three most common clinical forms are cervicofacial, thoracic, and abdominopelvic. On the contrary, nasopharyngeal actinomycosis is considered to be a rare clinical disease, and its occurrence is extremely low. The infection can take place without any preceding infection or on immunocompromised status. A 25-year-old male with no previous medical history presented with persistent nasal congestion and rhinorrhea. A nasal endoscopy examination revealed an unclearly demarcated nasopharyngeal mass, and a complete microbiology and pathology analysis showed actinomycetes colonies. After two weeks of oral Augmentin therapy, the patient's illness was completely eradicated. Diagnosis of nasopharyngeal actinomycosis is exceptionally crucial, and with early treatment of appropriate antibiotic therapy, the prognosis is excellent. Careful follow-up after adequate treatment as the possibility of frequent relapse is common.

Abstract
Artificial intelligence (AI) is an interdisciplinary field that encompasses a wide range of computer science disciplines, including image recognition, machine learning, human-computer interaction, robotics and so on. Recently, AI, especially deep learning algorithms, has shown excellent performance in the field of image recognition, being able to automatically perform quantitative evaluation of complex medical image features to improve diagnostic accuracy and efficiency. AI has a wider and deeper application in the medical field of diagnosis, treatment and prognosis. Nasopharyngeal carcinoma (NPC) occurs frequently in southern China and Southeast Asian countries and is the most common head and neck cancer in the region. Detecting and treating NPC early is crucial for a good prognosis. This paper describes the basic concepts of AI, including traditional machine learning and deep learning algorithms, and their clinical applications of detecting and assessing NPC lesions, facilitating treatment and predicting prognosis. The main limitations of current AI technologies are briefly described, including interpretability issues, privacy and security and the need for large amounts of annotated data. Finally, we discuss the remaining challenges and the promising future of using AI to diagnose and treat NPC.

Abstract
OBJECTIVE Approximately 30% of patients with a history of repaired cleft palate (CP) go on to suffer from velopharyngeal dysfunction (VPD). This study discusses the operative management of VPD and postoperative speech outcomes in a cohort of CP patients. SETTING An academic tertiary pediatric care center. METHODS Retrospective cohort study. PATIENTS Patients with history of repaired CP (Veau I-IV) who underwent operative management of VPD between January 1st, 2010 and December 31st, 2020. Operative modalities were posterior pharyngeal flap (PPF), sphincter pharyngoplasty (SPP), Furlow palate re-repair, and buccal myomucosal flap palate lengthening (PL). OUTCOME MEASURES The primary outcome measure is postoperative speech improvement evaluated by the Pittsburgh Weighted Speech Scale (PWSS). RESULTS 97 patients met inclusion criteria. 38 patients with previous straight-line primary palatoplasty underwent Furlow re-repair; these patients were significantly younger (7.62 vs 11.14, P < .001) and were more likely to have severe VPD per PWSS (OR 4.28, P < .01, 95% CI 1.46-12.56) when compared to VPD patients with previous Furlow repair. 21.1% of these patients required an additional non-revisional VPD procedure. The remaining patients underwent a non-revision procedure (26 PPF, 22 SPP, 11 PL); all experienced significant (P < .001 on paired t-test) reductions in PWSS total and subgroup VPD severity scores without difference in improvement between operation types. SPP was statistically associated with all-cause complication (OR 2.79, 95% CI 1.03-7.59, P < .05) and hyponasality (OR 3.27, 95% CI 1.112-9.630, P < .05). CONCLUSION Furlow re-repair reduced need for additional VPD operations. Speech outcomes between non-revisional operations are comparable, but increased complications were seen in SPP.

Abstract
A national survey of cleft teams was undertaken to evaluate the current standard of care for patients with cleft lip and palate (CLP) in India as a part of Cleft Care India study. This was a cross-sectional questionnaire-based study. Cleft teams across India attending the 19th Annual Conference of the Indian Society of Cleft Lip and Palate were invited to complete the questionnaire. The questionnaire consisted of 18 questions that included demographics, institutional details, patient protocols, surgical technique, rehabilitation facilities, and accessibility. The data are descriptively reported. A total of 112 centers completed the survey. Nongovernment organizations funded 87% of the cleft centers and 8% did not receive any funding. Only 39% of the centers had centralized cleft services providing multidisciplinary care. Speech therapy was provided either onsite or through referral at 90% of the centers, whereas audiology was provided only at 4% of centers. Feeding advice was routinely provided in 52% of centers. Millard technique was the most preferred technique for unilateral cleft lip repair (66%). The 2-flap technique (37%) and pharyngeal flap (48%) were the most common surgeries for cleft palate and pharyngoplasty, respectively. Although 54% of centers reported their patients to be interested in comprehensive care, 43% reported that their patients only wanted surgical correction. There is wide diversity in access to cleft care and clinical practices across centers in India. Further work is needed to evaluate the quality of care by assessing outcomes of centers treating patients with CLP.

Abstract
OBJECTIVES/HYPOTHESIS To develop a deep-learning-based automatic diagnosis system for identifying nasopharyngeal carcinoma (NPC) from noncancer (inflammation and hyperplasia), using both white light imaging (WLI) and narrow-band imaging (NBI) nasopharyngoscopy images. STUDY DESIGN Retrospective study. METHODS A total of 4,783 nasopharyngoscopy images (2,898 WLI and 1,885 NBI) of 671 patients were collected and a novel deep convolutional neural network (DCNN) framework was developed named Siamese deep convolutional neural network (S-DCNN), which can simultaneously utilize WLI and NBI images to improve the classification performance. To verify the effectiveness of combining the above-mentioned two modal images for prediction, we compared the proposed S-DCNN with two baseline models, namely DCNN-1 (only considering WLI images) and DCNN-2 (only considering NBI images). RESULTS In the threefold cross-validation, an overall accuracy and area under the curve of the three DCNNs achieved 94.9% (95% confidence interval [CI] 93.3%-96.5%) and 0.986 (95% CI 0.982-0.992), 87.0% (95% CI 84.2%-89.7%) and 0.930 (95% CI 0.906-0.961), and 92.8% (95% CI 90.4%-95.3%) and 0.971 (95% CI 0.953-0.992), respectively. The accuracy of S-DCNN is significantly improved compared with DCNN-1 (P-value <.001) and DCNN-2 (P-value = .008). CONCLUSION Using the deep-learning technology to automatically diagnose NPC under nasopharyngoscopy can provide valuable reference for NPC screening. Superior performance can be obtained by simultaneously utilizing the multimodal features of NBI image and WLI image of the same patient. LEVEL OF EVIDENCE 3 Laryngoscope, 2021.

Abstract
OBJECTIVE To assess outcomes after conversion Furlow palatoplasty with and without routine preoperative flexible fiberoptic video nasendoscopy (FFVN). DESIGN Retrospective cohort study. SETTING Tertiary Children's Hospital. PATIENTS Greater than 3 years of age with cleft palate and velopharyngeal insufficiency (VPI) after straight-line palatoplasty requiring secondary surgery performed with a Furlow palatoplasty. MAIN OUTCOME MEASURES The number of children with and without routine FFVN prior to conversion Furlow palatoplasty for VPI after initial straight-line palatoplasty. Groups were compared for surgical timing, speech outcomes, and need for additional surgery after conversion Furlow palatoplasty. RESULTS Fifty-eight patients underwent preoperative FFVN versus 29 without. Mean age at FFVN was 73.8 (SD 34) months. Mean age for secondary palatal surgery by conversion Furlow palatoplasty was 81.5 (SD 34.8) months with FFVN versus 73.4 (SD 34.0) months without FFVN. There was a significant difference (P < .001) for VPI diagnosis and time to surgery between the groups. Preoperative hypernasality ratings were similar between groups. Postoperatively 65.5% of FFVN and non-FFVN patients corrected to normal resonance. Only 6.9% of all patients rated moderate-severe hypernasality after surgery compared to 42.5% preoperatively. Of total, 5.7% of patients had unchanged hypernasality and only 1 patient rated worse. Seven patients ultimately required additional surgery in attempt to normalize their resonance. CONCLUSIONS Routine preoperative FFVN does not offer any advantage for improved outcomes in children undergoing conversion Furlow palatoplasty after straight-line repair. Routine preoperative FFVN was associated with increased time to surgery after diagnosis of VPI compared to those without FFVN.

Abstract
OBJECTIVE To develop an expert consensus statement on pediatric drug-induced sleep endoscopy (DISE) that clarifies controversies and offers opportunities for quality improvement. Pediatric DISE was defined as flexible endoscopy to examine the upper airway of a child with obstructive sleep apnea who is sedated and asleep. METHODS Development group members with expertise in pediatric DISE followed established guidelines for developing consensus statements. A search strategist systematically reviewed the literature, and the best available evidence was used to compose consensus statements regarding DISE in children 0 to 18 years old. Topics with significant practice variation and those that would improve the quality of patient care were prioritized. RESULTS The development group identified 59 candidate consensus statements, based on 50 initial proposed topics, that focused on addressing the following high-yield topics: (1) indications and utility, (2) protocol, (3) optimal sedation, (4) grading and interpretation, (5) complications and safety, and (6) outcomes for DISE-directed surgery. After 2 iterations of the Delphi survey and removal of duplicative statements, 26 statements met the criteria for consensus; 11 statements were designated as no consensus. Several areas, such as the role of DISE at the time of adenotonsillectomy, were identified as needing further research. CONCLUSION Expert consensus was achieved for 26 statements pertaining to indications, protocol, and outcomes for pediatric DISE. Clinicians can use these statements to improve quality of care, inform policy and protocols, and identify areas of uncertainty. Future research, ideally randomized controlled trials, is warranted to address additional controversies related to pediatric DISE.

Abstract
OBJECTIVES Awake nasopharyngoscopy is routinely performed in the assessment of patients who require treatment for sleep-disordered breathing (SDB). However, the applicability and accuracy of Müller's manoeuvre, the main evaluation method for this purpose, are disputable. The current study aimed to introduce an alternative method for awake nasopharyngoscopy in patients with SDB. DESIGN We defined qualitative anatomical features during tidal breathing at the levels of the soft palate, oropharynx, tongue base, epiglottis and hypopharynx, and compared these awake features to the sites and patterns of collapse as observed during drug-induced sleep endoscopy (DISE). SETTING Tertiary care academic centre. PARTICIPANTS Seventy-three patients diagnosed with SDB. MAIN OUTCOME MEASURES The primary outcome measure was the Kendall's tau correlation coefficient (τ) between observations during awake nasopharyngoscopy and DISE. Kappa-statistics (κ) were calculated to assess the agreement on awake endoscopic features with a second observer. RESULTS In contrast to epiglottis shape, the modified Cormack-Lehane scale was significantly associated with epiglottis collapse during DISE (P < .0001; τ = .45). Other upper airway features that were correlated with DISE collapse were the position of the soft palate (P = .007; τ = .29), crowding of the oropharynx (P = .026; τ = .32) and a posteriorly located tongue base (P = .046; τ = .32). Interobserver agreement of endoscopic features during tidal breathing was moderate (0.60 ≤ κ < 0.80). CONCLUSION The current study introduces a comprehensive and reliable assessment method for awake nasopharyngoscopy based on anatomical features that are compatible with DISE collapse patterns.

Abstract
OBJECTIVES/HYPOTHESIS Several recent studies have observed a high incidence of duodenoscope microbial contamination and an association of contamination with healthcare-acquired infections. This study sought to quantify nasopharyngoscope microbial contamination relative to that of other endoscope categories and characterize the manufacturers, outcomes, and microbial profiles associated with these cases. STUDY DESIGN Retrospective, cross-sectional study. METHODS A total of 3,865 adverse events were collected from 2013 to 2019 using the US Food and Drug Administration Manufacturer and User Facility Device Experience database. The fraction of total device failures associated with contamination was quantified for nasopharyngoscopes, bronchoscopes, duodenoscopes, and gastroscopes. Odds ratios of nasopharyngoscope contamination compared to that of bronchoscopes, duodenoscopes, or gastroscopes were calculated, and significance was assessed by χ2 analysis. The Kruskal-Wallis test was used for nonparametric testing of significance. RESULTS Nasopharyngoscope device failures were reported at an incidence of 0.646 per month; 34.1% involved contamination, comparable to the frequency observed for bronchoscopes (23.4%, P = .118), duodenoscopes (29.2%, P = .493), and gastroscopes (45.3%, P = .178). The frequency of device contamination was observed to be significantly higher for a particular endoscope manufacturer regardless of endoscope category (Kruskal-Wallis P = .021). In instances of contamination, nasopharyngoscopes were significantly less associated with patient harm or death than bronchoscope (odds ratio [OR] = 10.2) and duodenoscope (OR = 4.81) cases. CONCLUSIONS Although the rates of contamination were comparable across all endoscope categories, nasopharyngoscope contamination was less commonly associated with patient harm or death. In an era of rising healthcare costs, determining adequate disinfection standards for nasopharyngoscopes and their impact on patient safety is crucial.

Abstract
Primary nasopharyngeal tuberculosis, defined as an isolated tuberculosis infection of the nasopharynx without systemic or pulmonary disease, is rare, even in areas endemic for tuberculosis. It is challenging for ENT specialists to diagnose primary nasopharyngeal tuberculosis at an early stage. In this report, we describe a new case of primary nasopharyngeal tuberculosis, focusing on its nasopharyngoscopic features and radiological findings that can help the understanding and aid in accurate diagnosis of this unusual disease entity. Our experience suggests that although primary nasopharyngeal tuberculosis is a relatively rare disease, it must be included in the differential diagnosis of various nasopharyngeal lesions, particularly in patients with unusual nasopharyngoscopic and computed tomography findings.

Abstract
BACKGROUND Dynamic magnetic resonance imaging (MRI) has been proposed as a non-invasive, child-friendly, reproducible, and repeatable imaging method providing a 3-dimensional view of the velopharyngeal structures and function during speech. However, the value of dynamic MRI as compared to imaging methods such as nasopharyngoscopy is not well understood. The aim of this study was to compare the ability of nasopharyngoscopy and dynamic MRI to accurately identify velopharyngeal closure patterns among adults without cleft palate. METHODS Participants included 34 healthy adults with normal anatomy between 19 and 33 years of age (mean = 23 years; SD = 4.1 years). Participants underwent dynamic MRI and nasopharyngoscopy studies and comparisons were performed to determine the intra- and inter-rater reliability for accurately determining closure pattern. The MRI acquisition was a dynamic acquisition of a 2D plane. RESULTS Strong inter- (κ = .824; P < .001) and intra-rater (Rater 1: κ = 0.879, P < .001, 94% agreement between ratings; Rater 2 with 100% agreement) agreement was observed for the identification of closure pattern using nasopharyngoscopy. Inter-rater agreement for ratings using MRI demonstrated moderate agreement (κ = .489; P < .004). Examining point agreement revealed only 27 of the 33 ratings of MRI showed agreement (80%). CONCLUSION This demonstrates that inter-rater reliability for determining closure patterns from nasopharyngoscopy is good; however, ratings using MRI was less reliable at determining closure patterns. It is likely that future improvements in dynamic imaging with MRI to enable 3D visualizations are needed for improved diagnostic accuracy for assessing velopharyngeal closure patterns.

Abstract
PURPOSE Velo-cardio-facial syndrome (VCFS), the most common genetic syndrome causing cleft palate, is associated with internal carotid and vertebral artery anomalies, as well as upper airway asymmetry. Medially displaced internal carotid arteries, often immediately submucosal, present a risk of vascular injury during pharyngeal flap surgery for velopharyngeal insufficiency (VPI). We evaluate the frequency and spectrum of cervical vascular anomalies in a large cohort of VCFS patients correlating MRA with nasopharyngolaryngoscopy in detecting at risk carotid arteries. Furthermore, we assess the relationship with respect to laterality between cervical vascular patterns and the asymmetric abnormalities of these subjects' upper airways. METHODS Cervical MRAs of 86 subjects with VCFS and 50 control subjects were independently reviewed by three neuroradiologists. The course of the internal carotid and vertebral arteries was identified within the pharyngeal soft tissues. Medial deviation, level of bifurcation, dominance, anomalous origin, and vessel tortuosity were recorded. Nasopharyngoscopy examinations were available for retrospective review in 43 patients and were assessed for palatal and posterior pharyngeal wall symmetry, true vocal cord motion and size, and for the presence or absence of carotid pulsations. The endoscopic findings were compared with MRA results. RESULTS Of the 86 subjects, 80 (93%) had one or more vascular anomalies. 42 subjects (49%) were found to have medial deviation of at least one internal carotid artery. In 24 subjects (28%) the anomalous internal carotid artery was directly submucosal; four of these were bilateral (5% of the total sample, 17% of those with a submucosal internal carotid). Other carotid anomalies included low carotid bifurcation (44 subjects or 51%), anomalous origin of the right common carotid (32 cases, or 37%), and two cases of internal carotid agenesis/hypoplasia. Vertebral artery anomalies included vessel tortuosity (34 cases, or 40%), hypoplasia (10 cases, or 12%), looping (4 cases, or 5%), and one case of a double left vertebral artery. Though patients in our study showed an asymmetric distribution of vascular anomalies, no association was found between the laterality of palatal motion, pharyngeal fullness, or laryngeal movement and structure with ipsilateral vertebral or carotid artery anomalies. Of the 33 pulsatile carotid arteries visualized at nasopharyngoscopy, only nine were found to be submucosal on MRA. In contrast, 11 submucosal carotid arteries confirmed at MRA demonstrated no visible pulsations. Positive and negative predictive values of pulsative arteries seen endoscopically for MRA confirmation of a submucosal carotid course was 27% and 79% respectively. CONCLUSIONS Carotid and vertebral artery anomalies are common in VCFS including marked medial deviation of the internal carotid artery in close proximity to the donor site for pharyngeal flap surgery. Lack of correlation between laterality of vascular anomalies and upper airway structural asymmetry in VCFS does not support the hypothesis that palatal, pharyngeal, and laryngeal anomalies are due to secondary developmental sequences caused by in utero vascular insufficiency. The presence or absence of carotid pulsations seen by nasopharyngoscopy does not correlate with the carotid arterial depth identified on MRA. Furthermore, identification of the relative medial-lateral retropharyngeal position of a submucosal carotid affords the opportunity to modify the surgical approach. These findings further support the routine use of pre-operative neck MRA in VCFS patients in surgical planning.
