Objectives: This study aims to provide an overview of dizziness post head injury in those with prominent features for central vestibular dysfunction (CVD) in comparison to those with a post-traumatic peripheral vestibular etiology.

Study design: Retrospective.

Setting: University Health Network (UHN) Workplace Safety and Insurance Board (WSIB) database from 1988 to 2018 were evaluated for post-traumatic dizziness.

Methods: The UHN WSIB neurotology database (n = 4291) between 1998 and 2018 was retrospectively studied for head-injured workers presenting with features for CVD associated with trauma. All patients had a detailed neurotological history and examination, audiovestibular testing that included video nystagmography (VNG) and cervical vestibular-evoked myogenic potentials (cVEMPs). Imaging studies including routine brain and high-resolution temporal bone computed tomography (CT) scans and/or intracranial magnetic resonance imaging (MRI) were available for the majority of injured workers.

Results: Among 4291 head-injured workers with dizziness, 23 were diagnosed with features/findings denoting CVD. Complaints of imbalance were significantly more common in those with CVD compared to vertigo and headache in those with peripheral vestibular dysfunction. Atypical positional nystagmus, oculomotor abnormalities and facial paralysis were more common in those with CVD.

Conclusion: Symptomatic post-traumatic central vestibular injury is uncommon. It occurred primarily following high-impact trauma and was reflective for a more severe head injury where shearing effects on the brain often resulted in diffuse axonal injury. Complaints of persistent imbalance and ataxia were more common than complaints of vertigo. Eye movement abnormalities were highly indicative for central nervous system injury even in those with minimal change on CT/MRI.

Background: To assess the risk of depression in patients with chronic rhinosinusitis (CRS) in a tertiary care center and the effect of treatment on depression scores.

Methods: This prospective cohort study was conducted at King Faisal Specialist Hospital and Research Center, Riyadh, Saudi Arabia, between November 2021 and June 2022 and included adult patients (≥14 years) with CRS. The validated Arabic or English Sinonasal Outcome Test (SNOT-22) and Patient Health Questionnaire-9 (PHQ-9) were used before treatment and 3 to 6 months after surgery and maximal medical treatment. PHQ-9 scores were compared at baseline and follow-up visits. The relationship between changes in SNOT-22 and PHQ-9 scores were assessed using Spearman's correlation and simple linear regression.

Results: Overall, 38 participants with a mean ± SD age of 32.7 ± 12 years were enrolled. CRS with nasal polyps (55.26%) was the most frequently seen condition, followed by allergic fungal CRS (31.58%) and CRS without nasal polyps (13.16%). Six patients (15.7%) had PHQ-9 scores ≥10, indicating they had major depressive disorder. PHQ-9 and SNOT-22 scores improved significantly after treatment (3.7 ± 5.8 vs 6.5 ± 6.9 pretreatment, P = .001; 20.7 ± 20.5 vs 45.6 ± 28.9 pretreatment, P < .0001, respectively). Mean ± SD change in PHQ-9 and SNOT-22 scores was -2.7 ± 7 and -24.9 ± 29.8, respectively. SNOT-22 and PHQ-9 scores were positively correlated (r = .522, P < .001). PHQ-9 score change was significantly associated with SNOT-22 score change (β = .178, 95% confidence interval 0.12-0.23, P < .0001).

Conclusion: CRS affects the quality of life and psychological well-being of patients. Patient-centered care with maximal medical and surgical treatment help overcome its deleterious consequences.

Background: Diagnostic dilemma between clinical Meniere's disease and radiological endolymphatic hydrops (EH) has emerged since the introduction of hydrops magnetic resonance imaging (MRI). The aim of this study is to explore the potential application of hydrops MRI on diagnosing the EH.

Methods: This review was developed from peer-reviewed articles published in those journals listed on journal of citation reports. The MEDLINE database of the US National Library of Medicine, Scopus, and Google Scholar were used to collect articles based on the guidelines (PRISMA 2020 statement) for reporting reviews.

Results: Initially, 470 articles were retrieved from 1983 to 2023, and 80 relevant articles were ultimately selected. The sensitivity (69%-92%) and specificity (78%-96%) values varied from each laboratory for detecting EH via hydrops MRI, probably due to candidate selection and the grading system employed.

Conclusion: The application of hydrops MRI allows (1) differentiation between EH and sudden sensorineural hearing loss; (2) determination of the affected side of EH; and (3) confirmation of the diagnosis of EH concomitant with other disorders. Notably, not all differentials for EH can be visualized on MR images. One of the existing gaps to be filled is that updated hydrops MRI fails to identify distortion, that is, rupture, collapse, fistula, or fibrosis of the inner ear compartments, akin to what histopathological evidence can demonstrate. Hence, enhanced ultrahigh resolution of hydrops MRI is required for demonstrating fine structures of the inner ear compartments in the future.

Objectives: Eustachian tube dysfunction (ETD) is a common disease associated with chronic otitis media. A standard diagnostic tool for ETD in patients with tympanic membrane perforation is still lacking. We developed and validated a new diagnostic model for ETD in patients with tympanic membrane perforation.

Methods: A prospective study was conducted in patients who had tympanic membrane perforation from February to August 2023. We collected clinical characteristics and examination results including otoscopy, nasal endoscopy, tubomanometry, and 5-item Eustachian Tube Score (ETS-5). Univariate and multivariate logistic regression analysis was performed to determine the independent diagnostic factors. Based on this, the nomogram model was constructed. The discrimination and calibration of the nomogram were evaluated using the area under the curve (AUC), the C-index, the calibration curve, and the decision curve analysis (DCA).

Results: A total of 40 participants were enrolled in the study. ETS-5 score and Eustachian tube opening mucosa inflammation in the nasopharynx were significant predictors in identifying ETD. Based on the above independent predictors, a diagnostic nomogram was successfully established. The sensitivity and specificity of the diagnostic model were 80.0% and 90.0%, respectively. The AUC and the C-index of the diagnostic model were both 0.901, which suggested that the model had a good discrimination power. The calibration curve indicated a good calibration degree of the model. DCA showed that the proposed model was useful for clinical practice.

Conclusion: The nomogram model is effective and reliable in identifying ETD in patients with tympanic membrane perforation.

Background: The outcomes of recent advancements in pediatric tracheostomy remain unclear. This study was conducted to identify the trends in pediatric tracheostomy in Taiwan.

Methods: This population-based survey was conducted using data from Taiwan's National Health Insurance Research Database. We identified inpatients younger than 18 years who had undergone tracheostomy in Taiwan between 2000 and 2019. The study period was divided into subperiods (2000-2004, 2005-2009, 2010-2014, and 2015-2019). We analyzed patient characteristics and trends related to age, gender, hospital level, surgical indications, hospital stay duration, and mortality rates. The trends were analyzed for all pediatric patients (age <18 years) and infants (age <1 year).

Results: This study included 2465 pediatric patients (mean age: 8.7 ± 6.9 years; boys: 64%). The incidence of pediatric tracheostomy decreased from 3.3 events per 100,000 individuals in 2000 to 2.1 events per 100,000 individuals in 2019 (P for trend < .001). The proportion of infants who received tracheostomy increased from 22.8% in 2000-2004 to 32.5% in 2015-2019 (P for trend = .06). The proportion of pediatric patients who received tracheostomy at medical centers increased and those at regional hospitals or district hospitals decreased (74.7%-81.0% vs 25.3%-19.0%, P for trend = .003). The proportion of pediatric patients with trauma or brain injury as a surgical indication decreased from 36.6% to 28.7% (P for trend = .001). The duration of intensive care unit (ICU) stays increased from 30 days in 2000-2004 to 50 days in 2015-2019 (P for trend < .001), and that of hospital stay increased from 58 days in 2000-2004 to 71 days in 2015-2019 (P for trend = .001). The 5-year mortality rate slightly decreased from 38.0% in 2000-2004 to 33.3% in 2005-2009 and 31.0% in 2010-2014 (P for trend = .006).

Conclusions: Our findings revealed that during the study period, the number of pediatric patients receiving tracheostomy decreased, but the proportion of infants receiving tracheostomy increased. The trends in pediatric tracheostomy indicated extended ICU stay, prolonged hospital stay, and reduced 5-year mortality rates.

Importance: Metastases to the submandibular gland (SMG) from oral cavity primaries are very rare. Hence, a gland-preserving level IB dissection technique is a feasible option without compromising the lymph node yield (LNY).

Objective: To assess the feasibility and noninferiority of the SMG-preserving dissection technique to the conventional en bloc removal of level IB in terms of LNY in patients with cN0 oral squamous cell carcinoma (OSCC) undergoing elective neck dissection.

Design: Parallel-design, single-center, open-label, randomized controlled trial.

Setting: Tertiary care health care center-Department of Otorhinolaryngology-Head & Neck Surgery, AIIMS Rishikesh.

Participants: Thirty-eight (n = 38) participants with 46 (n = 46) neck dissection specimens of OSCC were randomly allocated (1:1) into gland-preserving (n₁ = 23) and en bloc (n₂ = 23) dissection groups.

Intervention: Elective neck dissection comparing SMG-sparing level IB dissection technique versus en bloc level IB dissection.

Main outcome measures: LNY, lymph node density, and level IB operative time in both groups were compared between groups (α < .05).

Results: Median LNY (P = .543) and lymph node density (P = 1.000) in level IB did not show significant differences between the groups. LNY in level IB by gland-preserving technique is also not inferior to the conventional en bloc dissection technique (mean difference = 0.217; 95% CI: [-0.597, 1.032]; P = .593). The mean level IB operative time is significantly longer in the gland-preserving group (P < .001).

Conclusions and relevance: None of the examined SMGs were involved by the tumor. SMG-preserving technique is noninferior to the traditional technique of level IB clearance and can be used in elective neck dissections without compromising the LNY. Functional neck dissection has greatly evolved to decrease patient morbidity, and this method can be adopted in case-specific situations.

Trial registration: The trial was registered in the Clinical Trials Registry-India (CTRI/2022/05/042344) on May 2, 2023, https://ctri.nic.in/.

Introduction: The routine assessment of intraoperative margins has long been the standard of care for oral cavity cancers. However, there is a controversy surrounding the best method for sampling surgical margins. The aim of our study is to determine the precision of a new technique for sampling tumor bed margins (TBMs), to evaluate the impact on survival and the rate of free flap reconstructions.

Methods: This retrospective cohort study involved 156 patients with primary cancer of the tongue or floor of the mouth who underwent surgery as initial curative treatment. Patients were separated into 2 groups: one using an oriented TBM derived from Mohs' technique, where the margins are taken from the tumor bed and identified with Vicryl sutures on both the specimen and the tumor bed, and the other using a specimen margins (SMs) driven technique, where the margins are taken from the specimen after the initial resection. Clinicopathologic features, including margin status, were compared for both groups and correlated with locoregional control. Precision of per-operative TBM sampling method was obtained.

Results: A total of 156 patients were included in the study, of which 80 were in TBM group and 76 were in SM group. Precision analysis showed that the oriented TBM technique pertained a 50% sensitivity, 96.6% specificity, 80% positive predictive value, and an 87.5% negative predictive value. Survival analysis revealed nonstatistically significant differences in both local control (86.88% vs 83.50%; P = .81) as well as local-regional control (82.57% vs 72.32%; P = .21). There was a significant difference in the rate of free flap-surgeries between the 2 groups (30% vs 64.5%; P < .001).

Conclusion: Our described oriented TBM technique has demonstrated reduced risk of free flap reconstructive surgery, increased precision, and similar prognostic in terms of local control, locoregional control, and disease-free survival when compared to the SM method.

Background: The bedside head impulse test (bHIT) is a clinical method of assessing the vestibulo-ocular reflex. It is a critical component of the bedside assessment of dizzy patients and helps differentiate acute stroke from vestibular neuritis. A previous study on senior Otolaryngology residents showed poor competence in performing and interpreting the bHIT and called for specific evaluations in the Competency By Design (CBD) curriculum to remedy this. This study aimed to assess whether those competencies have improved after full implementation of CBD in residency programs.

Methods: Thirty post-graduate year 4 Otolaryngology residents in Canada were evaluated on the use of the bHIT using a written multiple-choice question (MCQ) examination, interpretation of bHIT videos, and performance of a bHIT. Ratings of bHIT performance were completed by 2 expert examiners (DT, DL) using the Ottawa Clinic Assessment Tool.

Results: Only 6.7% (rater DT) and 20% (rater DL) of residents were found able to perform the bHIT independently. Inter-rater reliability was moderate (0.55, intraclass correlation). Mean scores were 70% (13.4% standard deviation) for video interpretation and 59% (20.6% standard deviation) for multiple-choice questions. Video interpretation scores did not correlate with bHIT ratings (Pearson r = 0.11), but MCQs and bHIT ratings did correlate moderately (Pearson r = 0.52).Comparing to the prior study, residents performed worse on the bHIT (3.14 average score vs 3.64, P < .01) and fewer residents performed the bHIT independently (6.7% vs 22%-rater DT, 20% vs 39%-rater DL). Residents also performed worse on MCQs (58.7% vs 70.9%, P = 0.038), though similarly on video interpretation (70% vs 65%, P = .198).

Conclusion: Fourth year OTL-HNS residents in Canada are not competent in performing the bHIT. These findings have implications for refining competency-based curricula in the evaluation of critical physical exam skills.

Objective: To review the current literature about surgical treatments of pediatric bilateral vocal fold paralysis (PBVFP).

Methods: A systematic review of the current literature in PubMed, Scopus, and Cochrane Library regarding etiologies and management of PBVFP was performed until November 2023 according to PRISMA statements. Quality assessment was assessed with Methodological Index for Non-Randomized Studies (MINORS) tool.

Results: Of the 211 screened articles, 26 were included accounting for 320 patients. The etiologies included idiopathic (42.2%), congenital (19.7%), neurological (16.9%), or post-surgical (9.5%) pediatric bilateral vocal cord paralysis (PBVCP). Patients were decannulated in 76.7% of cases without laryngeal procedure. Decannulation was achieved in 84.6%, 66.6%, 83.3%, 80.0%, and 62.5% of cases of laterofixation of the vocal fold, cricoid split approaches, partial or total arytenoidectomy, uni- or bilateral transverse cordotomy, and selective laryngeal reinnervation, respectively. Dyspnea/stridor relief, swallowing, or voice quality outcomes were used in some studies, which reported conflicting results. Revision and complications varied between studies, with complications mainly involving edema, granuloma, or aspirations. Revision was required in 6.4%, 12.9%, and 40.0% of cases that underwent laterofixation of the vocal fold, arytenoidectomy, and cricoid split procedures, respectively. There was substantial heterogeneity across studies in inclusion criteria, procedures, and outcomes.

Conclusion: The management of PBVFP may involve several temporary or permanent surgical procedures that are associated with overall subjective improvements of symptoms, and laryngeal findings. The retrospective design of studies, the small number of cohorts, the lack of objective outcomes, and the differences between teams regarding procedure timing and features limit drawing reliable conclusions about the superiority of one technique over others.

Background: Correctly diagnosing dizziness in children is essential for appropriate management; nevertheless, healthcare professionals face challenges due to children's limited ability to describe their symptoms and their cooperation during physical examination. The objective of this study is to describe the first 100 patients seen at a newly established pediatric vertigo center.

Methods: This is a retrospective review of a consecutive series of 100 patients seen at our pediatric vertigo clinic in a tertiary referral center from August 2019 until June 2022. Comprehensive clinical data were collected. The diagnoses were established by 2 pediatric otolaryngologists based on validated diagnostic criteria. Trends in diagnosis, investigation, and treatment of these patients were analyzed.

Results: A total of 100 children were included in the study. Vestibular migraine was the most common diagnosis (20%) followed by benign paroxysmal vertigo of childhood (14%). Eleven patients had combined pathologies. Fifteen out of 70 children (21%) had abnormal audiograms, 30 out of 48 children (62.5%) had abnormal vestibular testing, and 6 out of 31 (19%) patients had abnormal imaging. Fifty-one children received medical treatment, 23 received vestibular physiotherapy, and 9 patients had particle repositioning maneuvers; moreover, 17 of these patients received multimodal treatment.

Conclusions: Our analysis suggests that imaging and audiology testing have relatively low yield in the assessment of pediatric vertigo. On the other hand, vestibular testing detected a high proportion of abnormalities, such as saccadic pursuit, vertical nystagmus, central positional nystagmus, and abnormal directional preponderance, particularly associated with vestibular migraine. Given the complexity of diagnosing vertigo in children, it is critical to establish multidisciplinary specialized centers capable of providing accurate diagnosis and treatment for these children.
