RESUMEN
This pilot study examines the use of surgical instrument tracking and motion analysis in objectively measuring surgical performance. Accuracy of objective measures in distinguishing between surgeons of different levels was compared to that of subjective assessments. Twenty-four intraoperative video clips of mastoidectomies performed by junior residents (n = 12), senior residents (n = 8), and faculty (n = 4) were sent to otolaryngology programs via survey, yielding 708 subjective ratings of surgical experience level. Tracking software captured the total distance traveled by the drill, suction irrigator, and patient's head. Measurements were used to predict surgeon level of training, and accuracy was estimated via area under the curve (AUC) of receiver operating characteristic curves. Key objective metrics proved more accurate than subjective evaluations in determining both faculty vs resident level and senior vs junior resident level. The findings of this study suggest that objective analysis using computer software has the potential to improve the accuracy of surgical skill assessment.

IMPORTANCE: Subtotal petrosectomy (STP) has been more frequently performed to prepare ears with unfavorable conditions for cochlear implantation. OBJECTIVES: To provide an overview of indications for and complications of STP and cochlear implantation and to compare outcomes between single vs multistage procedures and between pediatric vs adult populations. DATA SOURCES: A search of PubMed, Scopus, Ovid, and the Cochrane Library was performed from the databases' inception to January 23, 2020, for studies evaluating STP for cochlear implantation. STUDY SELECTION: Studies with a minimum follow-up of 3 months and no missing data regarding postoperative outcomes were included. Of the initial 570 studies identified, 27 (4.7%) met selection criteria. DATA EXTRACTION AND SYNTHESIS: Two reviewers independently assessed study eligibility according to Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines; discrepancies were resolved by a third reviewer. Extracted data included patient demographics, indications for STP, rates of complications, and cholesteatoma recidivism when applicable. Data were pooled using a random- or a fixed-effects model when appropriate. MAIN OUTCOMES AND MEASURES: The primary study outcome was rate of global complications stratified by patient- and surgery-level characteristics. RESULTS: Twenty-seven unique studies with 377 unique patients (54.2% male; mean age, 50.6 [range, 1-99] years) undergoing 397 STP procedures and cochlear implantation were included. Of these procedures, 299 of 394 cases with the information reported (75.9%) were single procedures and 95 (24.1%) were multistage procedures. Of the total 397 STP procedures, most common indications included chronic otitis media (220 cases [55.4%]), previous open mastoid cavity (141 [35.5%]), cholesteatoma (74 [18.6%]), and cochlear ossification (29 [7.3%]). The overall complication rate was 12.4% (95% CI, 9.4%-15.9%); overall cholesteatoma recidivism rate was 9.3% (95% CI, 4.3%-17.1%). Complication rates did not significantly differ based on stage or age of patients. Cases with cholesteatoma more often underwent multistage vs single-stage procedures (23 of 54 [42.6%] vs 35 of 174 [20.1%]). CONCLUSIONS AND RELEVANCE: Across all age groups, STP has been shown to be an effective surgical operation in preparing an ear with unfavorable conditions for cochlear implantation. The potential indications for which cochlear implantation can be performed have expanded with the use of STP. Presence of cholesteatoma might indicate that a multistage procedure should be performed. Lastly, with complication rates comparable to those in adult patients, STP can be considered in children requiring cochlear implantation to minimize ear-related issues and allow benefit from cochlear implantation.
RESUMEN
Importance: Otolaryngology residency programs currently lack rigorous methods for assessing surgical skill and often rely on biased tools of evaluation. Objectives: To evaluate which techniques used in mastoidectomy can serve as indicators of surgeon level (defined as the level of training) and whether these determinations of technique can be made based solely on the movement of the drill head or suction. Design, Setting, and Participants: In this prospective, observational study conducted from January 1, 2015, to December 31, 2019, at a single tertiary care institution, 3 independent observers made blinded evaluations on 24 intraoperative recordings of surgeons (6 junior residents, 4 senior residents, and 2 attending surgeons) performing mastoidectomies. Main Outcomes and Measures: Observers assessed drill stroke count, drilling efficiency, stroke pattern, use of suction and irrigation, and estimated surgeon level. Assessments were made on both original videos and animated videos that show only the path of the burr head or suction as dots against a white background. Results: Among the 24 recorded mastoidectomies performed by the 12 study surgeons, intraclass correlation was excellent for original video assessment of drill stroke count (0.98 [95% CI, 0.97-1.00]), use of suction (0.75 [95% CI, 0.52-0.89]), use of irrigation (0.83 [95% CI, 0.66-0.92]), and estimated surgeon level (0.82 [95% CI, 0.64-0.92]) and fair for drilling efficiency (0.54 [95% CI, 0.09-0.79]) and stroke pattern (0.49 [95% CI, -0.02 to 0.76]). Intraclass correlation was excellent for animated video assessment of drill stroke count per unit time (0.98 [95% CI, 0.96-0.99]) and drilling efficiency (0.80 [95% CI, 0.60-0.91]), good for stroke pattern (0.68 [95% CI, 0.38-0.85]) and estimated surgeon level (based on path of drill) (0.69 [95% CI, 0.38-0.85]), and fair for use of suction (0.58 [95% CI, 0.16-0.80]) and estimated surgeon level (based on path of suction) (0.58 [95% CI, 0.17-0.80]). On evaluation of original videos, junior residents had lower drill stroke count compared with senior residents and attending surgeons (6.0 [interquartile range (IQR), 3.0-8.0] vs 9.5 [IQR, 5.0-13.0] vs 10.5 [IQR, 5.0-17.8]; η2 = 0.14 [95% CI, 0.01-0.28]). On evaluation of animated videos, junior residents also had lower drill stroke count compared with senior residents and attending surgeons (6.0 [IQR, 4.0-9.0] vs 10.5 [IQR, 10.0-13.8] vs 10.5 [IQR, 4.3-21.0]; η2 = 0.19 [95% CI, 0.04-0.33]). Compared with junior and senior residents, attending surgeons had higher median ratings of drilling efficiency (original videos: junior residents, 4.0 [IQR, 3.0-4.0]; senior residents, 4.0 [IQR, 3.0-4.8]; attending surgeons, 5.0 [IQR, 4.3-5.0]; η2 = 0.23 [95% CI, 0.06-0.37]; animated videos: junior residents, 4.0 [IQR, 3.0-4.0]; senior residents, 3.0 [IQR, 2.0-4.0]; attending surgeons, 5.0 [IQR, 4.0-5.0]; η2 = 0.25 [95% CI, 0.08-0.39]) and stroke pattern (original videos: junior residents, 4.0 [IQR, 3.0-4.0]; senior residents, 4.0 [IQR, 3.0-4.8]; attending surgeons, 5.0 [IQR, 5.0-5.0]; η2 = 0.17 [95% CI, 0.03-0.31]; animated videos: junior residents, 4.0 [IQR, 3.0-4.0]; senior residents, 4.0 [IQR, 2.0-4.0]; attending surgeons, 5.0 [IQR, 5.0-5.0]; η2 = 0.15 [95% CI, 0.02-0.29]). Conclusions and Relevance: This study suggests that observation of intraoperative mastoidectomy recordings is a feasible method of evaluating surgeon level. Reasonable indicators of surgeon level include the drill stroke count, drilling efficiency, stroke pattern, and use of the suction irrigator. Observing the path of the drill alone is sufficient to appreciate differences in drilling technique but not sufficient to accurately determine surgeon level. Intraoperative recordings can serve as a useful addition to resident education and evaluation.

STUDY OBJECTIVES: To determine the incidence, duration, and predictors of swallowing-related symptoms following upper airway surgery for obstructive sleep apnea. METHODS: Adults (age 18 years or older) who underwent surgery for obstructive sleep apnea at a tertiary care institution from January 2012 to December 2015 were retrospectively reviewed. The incidence, duration, and associated factors of postoperative swallowing complaints were evaluated. RESULTS: A total of 130 patients (135 surgical encounters) met criteria for inclusion. There were 91 men (70.0%) and 39 women (30.0%) with a median age of 60 years (range: 19-79). Presurgical diagnosis of gastroesophageal reflux disease was present in 57 patients (43.8%). An average of 2.1 procedures (± 0.8) were conducted at each encounter. Uvulopalatopharyngoplasty (54.8%) was the most common followed by radiofrequency ablation of the soft palate (34.8%) and tongue base (29.6%). Postoperatively, 25 patients (19.8%) complained of dysphagia, 14 (10.9%) of globus, and 9 (6.7%) of odynophagia. Preoperative gastroesophageal reflux (odds ratio [OR] 4.09, 95% confidence interval [CI] 1.41-11.91) and hyoid myotomy with suspension (OR 4.88, 95% CI 1.34-17.77) were significant predictors for dysphagia. Radiofrequency ablation of the tongue base (OR 5.00, 95% CI 1.28-19.50) was a predictor for globus sensation. Median symptom durations, in months, were 4.0 for dysphagia, 7.3 for globus, and 3.0 for odynophagia. CONCLUSIONS: Preoperative gastroesophageal reflux and hyoid myotomy with suspension procedure were associated with postoperative dysphagia whereas radiofrequency ablation of the tongue base was associated with globus. These findings can assist surgeons in providing preoperative counseling and postoperative supportive measures regarding dysphagic symptoms following sleep surgery.

OBJECTIVES: Singers and voice teachers are exposed to a range of noise levels during a normal working day. This study aimed to assess the hearing thresholds in a large sample of generally healthy professional voice teachers and voice students to determine the prevalence of hearing loss in this population. STUDY DESIGN: A cross-sectional study was carried out. METHODS: Voice teachers and vocal students had the option to volunteer for a hearing screening of six standard frequencies in a quiet room with the Shoebox audiometer (Clearwater Clinical Limited) and to fill out a brief survey. Data were analyzed for the prevalence and severity of hearing loss in teachers and students based on several parameters assessed in the surveys. All data were analyzed using Microsoft Excel (Microsoft Corp.) and SPSS Statistics Software (IBM Corp.). RESULTS: A total of 158 participants were included: 58 self-identified as voice teachers, 106 as voice students, and 6 as both. The 6 participants who identified as both, were included in both categories for statistical purposes. Of the 158 participants, 36 had some level of hearing loss: 51.7% of voice teachers had hearing loss, and 7.5% of voice students had hearing loss. Several parameters of noise exposure were found to positively correlate with hearing loss and tinnitus (P < 0.05). Years as a voice teacher and age were both predictors of hearing loss (P < 0.05). CONCLUSIONS: Hearing loss in a cohort of voice teachers appears to be more prevalent and severe than previously thought. There is a significant association between years teaching and hearing loss. Raising awareness in this population may prompt teachers and students to adopt strategies to protect their hearing.
