Laryngotracheal Reconstruction for Subglottic and Tracheal Stenosis.

Laryngotracheal stenosis is the common endpoint for any process that results in the narrowing of the airway at the level of the glottis, subglottis, or trachea. Although endoscopic procedures are effective in opening the airway lumen, open resection and reconstruction can be necessary to reconstitute a functional airway. When resection and anastomosis are insufficient due to extensive length or location of the stenosis, autologous grafts can be used to expand the airway. Future directions in airway reconstruction include tissue engineering and allotransplantation.

Resident Education in Laryngeal Stroboscopy: Part II-Evaluation of a Multimedia Training Module.

OBJECTIVE: To evaluate the efficacy of a web-based training module for teaching interpretation of laryngeal stroboscopy in a cohort of otolaryngology residents. STUDY DESIGN: Randomized controlled trial. SETTING: Academic tertiary center. SUBJECTS AND METHODS: Residents from three training programs were invited to complete an assessment consisting of a survey and five stroboscopic exams. Subsequently, participants were randomized to receive teaching materials in the form of (1) a handout (HO) or (2) a multimedia module (MM) and asked to complete a post-training assessment. Responses were compared to responses provided by three fellowship-trained laryngologists. RESULTS: Thirty-five of 47 invited residents (74.4%) completed both assessments. Overall mean postassessment scores were 64.3% ± 7.0, with the MM group (67.0% ± 7.6, n = 17) scoring higher (P = 0.03) than the HO (61.6% ± 5.4, n = 18) cohort. Postassessment scores did not differ by postgraduate year (P = 0.75) or institution (P = 0.17). Paired analysis demonstrated an overall mean improvement of 7.4% in the handout (HO) cohort (P = 0.03) and 10.3% in the MM cohort (P = 0.0006). Subset analysis demonstrated higher scores for the MM cohort for perceptual voice evaluation (HO = 68.8% ± 11.0; MM = 77.3% ± 10.6, P = 0.03) and stroboscopy-specific items (HO = 55.5% ± 8.2; MM = 61.9% ± 10.8, P = 0.06). On a five-point Likert scale, residents reported improved confidence in stroboscopy interpretation (P < 0.0001), irrespective of cohort (P = 0.62). Residents rated the MM (median = 5) more favorably as a teaching tool compared to the HO (median = 4, P = 0.001). CONCLUSION: Use of both the written HO and MM module improved scores and confidence in interpreting laryngeal stroboscopy. The MM was more effective in perceptual voice evaluation and stroboscopy-specific items. The MM was also rated more favorably by residents and may be an ideal adjunct modality for teaching stroboscopy.

Resident Education in Laryngeal Stroboscopy and Perceptual Voice Evaluation: An Assessment.

OBJECTIVES: To evaluate otolaryngology residents' level of confidence and understanding in interpreting laryngeal stroboscopy. METHODS: Otolaryngology residents from three residency programs with fellowship-trained laryngologists on faculty were invited to participate. An assessment consisting of a survey and five stroboscopic exams was administered. Each exam consisted of questions on perceptual voice evaluation, laryngoscopic findings, and stroboscopic findings. Scores were compared to answers provided by three fellowship-trained laryngologists. RESULTS: Thirty-eight of 47 invited residents (80.8%) enrolled in the study. On a five-point likert scale, residents reported low confidence (median = 2, range = 1-4) in interpreting stroboscopy, regardless of training program (P = 0.81). Mean assessment scores were 56.5% ± 11.9, with scores in perceptual voice evaluation = 68.5% ± 10.6; laryngoscopy = 70.2% ± 12.8; and stroboscopy = 45.3% ± 17.8. Residents performed worse on stroboscopy questions compared to laryngoscopy questions (P < 0.0001). There was a significant difference in scores by postgraduate year (P = 0.03), but not by institution (P = 0.34). A moderately positive correlation between reported level of confidence and overall scores (ρ = .47, P = 0.003) was demonstrated. CONCLUSIONS: Despite didactic and clinical exposure, residents report low confidence in interpreting stroboscopy and scored lower on stroboscopy-specific questions compared to other assessment items. Additional resources and learning opportunities are needed to improve resident confidence and comprehension of stroboscopy.

Pathology protocol increases lymph node yield in neck dissection for oral cavity squamous cell carcinoma.

BACKGROUND: Lymph node yield (LNY) is a proposed quality indicator in neck dissection for oral cavity squamous cell carcinoma (OCSCC). METHODS: Retrospective series including 190 patients with OCSCC undergoing neck dissection between 2016 and 2018. A change in pathologic grossing protocol was initiated during the study period to assess residual adipose tissue. A generalized linear model was used to assess the impact of multiple variables on LNY. RESULTS: Mean LNY was 28.59 (SD = 17.65). The protocol identified a mean of 10.32 lymph nodes per case. Multivariable analysis identified associations between LNY and use of the pathology protocol (P = .02), number of dissected lymph node levels (P < .001), presence of pathologic lymph nodes (P = .002), body mass index (P = .02), prior neck surgery (P = .001), and prior neck radiation (P = .001). CONCLUSIONS: Assessment of residual adipose tissue within neck dissection specimens improves accuracy of LNY. LNY in neck dissection is influenced by multiple factors including methods of pathologic assessment.

Airway Anomalies in Patients With 22q11.2 Deletion Syndrome: A 5-Year Review.

OBJECTIVES: To characterize the frequency of airway anomalies in patients with 22q11.2 deletion syndrome (22q11DS). METHODS: Retrospective review of patients with 22q11DS who had undergone microlaryngoscopy/bronchoscopy (MLB) for aerodigestive symptoms at a tertiary care children's hospital from 2011 to 2016. RESULTS: Thirty patients underwent an MLB due to the following indications: aspiration (11), stridor (10), chronic respiratory failure due to ventilator dependence (8), and difficult intubation (1). Median age at MLB was 6.5 months (range, 0.25-32 months). Forty airway anomalies were identified in 20 (66%) patients. Laryngomalacia (10), tracheomalacia (8), and bronchomalcia (8) were the most common intraoperative findings, followed by laryngeal cleft (5), anterior glottic web (5), subglottic stenosis (3), and subglottic cysts (1). Synchronous airway anomalies were common and identified in 11 (55%) of the patients who had identified anomalies on MLB. Nineteen of the 20 patients required operative intervention due to the anomalies identified. CONCLUSIONS: Structural airway abnormalities are common in children with 22q11DS undergoing MLB, and synchronous anomalies can frequently exist. Providers caring for children with 22q11DS should be vigilant about airway evaluation when aerodigestive symptoms are present.

Steroid Versus Antibiotic Drops in the Prevention of Postoperative Myringotomy Tube Complications.

OBJECTIVES: To determine the incidence of early postoperative tympanostomy tube insertion otorrhea and obstruction in pediatric patients receiving antibiotic ear drops with or without steroid perioperatively. METHODS: A retrospective chart review was performed on patients who underwent outpatient myringotomy and tube placement. Patients from June 2013 to February 2014 received ciprofloxacin/dexamethasone perioperatively while patients from May 2014 to April 2015 received ofloxacin. Statistical analysis was performed to compare outcomes between the cohorts. RESULTS: One hundred thirty-four patients received topical ciprofloxacin/dexamethasone, and 116 patients received topical ofloxacin. The rate of postoperative otorrhea was 5.2% for the ciprofloxacin/dexamethasone group and 8.2% for the ofloxacin group. Tube obstruction was seen in 6.0% of the ciprofloxacin/dexamethasone group and 5.2% in the ofloxacin group. Neither outcome had a statistically significant difference ( P = .21 and .85, respectively). There was no difference in the rate of effusion at the time of tube placement between the 2 cohorts ( P = .16), and this included subgroup analysis based on effusion type (mucoid, purulent, serous). Patients with a mucoid effusion at the time of surgery were more likely to experience otorrhea/obstruction than patients with dry ears (odds ratio = 2.23, P = .02). CONCLUSION: No significant difference in the incidence of immediate postoperative tympanostomy tube otorrhea or obstruction was seen between the antibiotic-steroid and antibiotic alone cohorts, regardless of effusion type. Overall, patients with mucoid effusions are more likely to develop tube otorrhea or obstruction at follow-up. Cost-effective drops should be used when prescribing topical therapy to prevent complications after ear tubes.
