Oncologic outcomes of human papillomavirus-associated oropharynx carcinoma treated with surgery alone: A 12-institution study of 344 patients.

BACKGROUND: The oncologic outcomes of surgery alone for patients with American Joint Committee on Cancer 7th edition (AJCC 7th) pN2a and pN2b human papillomavirus-associated oropharynx squamous cell carcinoma (HPV+OPSCC) are not clear. METHODS: The authors performed a 12-institution retrospective study of 344 consecutive patients with HPV+OPSCC (AJCC 7th pT0-3 N3 M0) treated with surgery alone with 6 months or more of follow-up using univariate and multivariate analyses. RESULTS: The 2-year outcomes for the entire cohort were 91% (182 of 200) disease-free survival (DFS), 100% (200 of 200) disease-specific survival (DSS), and 98% (200 of 204) overall survival (OS). The 18 recurrences within 2 years were 88.9% (16 of 18) local and/or regional recurrences and 11.1% (2 of 18) distant metastases. Recurrences were not significantly associated with smoking, pT stage, or pN stage. The 16 patients with locoregional recurrences within 2 years all underwent successful salvage treatments (median follow-up after salvage: 13.1 months), 43.8% (7 of 16) of whom underwent salvage surgery alone for a 2-year overall salvage radiation need of 4.5% (9 of 200). The 2-year outcomes for the 59 evaluable patients among the 109 AJCC 7th pT0-2 N2a-N2b patients with 1 to 3 pathologic lymph nodes (LNs) were as follows: local recurrence, 3.4% (2 of 59); regional recurrence, 8.4% (5 of 59); distant metastases, 0%; DFS, 88.1% (52 of 59); DSS, 100% (59 of 59); OS, 96.7% (59 of 61); and salvage radiation, 5.1% (3 of 59). CONCLUSIONS: With careful selection, surgery alone for AJCC 7th pT0-T2N0-N2b HPV+OPSCC with zero to 3 pathologic LNs without perineural invasion, extranodal extension, or positive margins results in high DFS, DSS, OS, and salvage treatment success. Because of the short-term follow-up, these data support further investigation of treatment de-escalation in this population.

Pre-clinical remote undergraduate medical education during the COVID-19 pandemic: a survey study.

BACKGROUND: The Coronavirus Disease 2019 (COVID-19) pandemic has necessitated a sudden transition to remote learning in medical schools. We aimed to assess perceptions of remote learning among pre-clinical medical students and subsequently to identify pros and cons of remote learning, as well as uncover gaps to address in ongoing curricular development. METHODS: A survey was distributed to first- and second-year medical students at the University of California San Diego School of Medicine in March 2020. Frequencies of responses to structured multiple-choice questions were compared regarding impacts of remote learning on quality of instruction and ability to participate, value of various remote learning resources, living environment, and preparedness for subsequent stages of training. Responses to open-ended questions about strengths and weaknesses of the remote curriculum and overall reflections were coded for thematic content. RESULTS: Of 268 students enrolled, 104 responded (53.7% of first-year students and 23.9% of second-year students). Overall, students felt that remote learning had negatively affected the quality of instruction and their ability to participate. Most (64.1%) preferred the flexibility of learning material at their own pace. Only 25.5% of respondents still felt connected to the medical school or classmates, and feelings of anxiety and isolation were noted negatives of remote learning. Most second-year students (56.7%) felt their preparation for the United States Medical Licensing Examination Step 1 exam was negatively affected, and 43.3% felt unprepared to begin clerkships. In narrative responses, most students appreciated the increased flexibility of remote learning, but they also identified several deficits that still need to be addressed, including digital fatigue, decreased ability to participate, and lack of clinical skills, laboratory, and hands-on learning. CONCLUSIONS: Videocasted lectures uploaded in advance, electronic health record and telehealth training for students, and training for teaching faculty to increase technological fluency may be considered to optimize remote learning curricula.

Clinician accuracy in identifying essential laryngeal landmarks on swallowing fluoroscopy.

Objective: Identification of anatomical landmarks is essential for interpretation of video fluoroscopic swallow studies (VFSS). This investigation sought to confirm the location of essential laryngeal landmarks and determine clinician accuracy in structure identification on VFSS. Methods: A single human cadaver was used to generate unmarked standard lateral and anterior-posterior (AP) fluoroscopic images. Essential laryngeal structures (e.g., true vocal fold, arytenoid) were directly identified using a guidewire placed through an endoscope while obtaining corresponding marked fluoroscopic images. Licensed clinicians (speech-language pathologists [SLP], laryngologists) and trainees (otolaryngology residents, SLP clinical fellows [CF]) identified 18 structures (9 lateral, 9 AP) on unmarked images. Answers were compared to corresponding marked images. The percentage of accurate identification was calculated for each clinician and then compared between groups using t-tests. Results: Twenty-four individuals (10 SLPs, 1 CF, 9 residents, 4 laryngologists) from six institutions completed structure identification. Mean overall accuracy was 41.7 ± 13.0% (range 18.8-68.8%). There were no significant differences in mean overall accuracy between trainees (41.9 ± 12.9%) and clinicians (42.0 ± 13.1%), p = .97, or between SLPs (45.5 ± 12.8%) and physicians (38.9 ± 12.3%), p = .22. On average, participants were significantly more accurate identifying structures on lateral view (53.1 ± 16.1%) than AP (27.3 ± 22.8%), p < .001. Less than half of participants accurately identified the laryngeal ventricle, cricoid, epiglottic petiole, and the anterior commissure on lateral view. Conclusions: The ability of certified clinicians and trainees to correctly identify essential anatomic landmarks on swallowing fluoroscopy may be poor. Future work is needed to identify how we can train clinicians on more accurate identification of essential anatomic structures on swallowing fluoroscopy.Level of Evidence: NA.

Depression in the Pediatric Otolaryngology Clinic Setting.

OBJECTIVES/HYPOTHESIS: For most pediatric specialty clinics, mental health is not the primary presenting complaint, yet can portend unrecognized morbidity. We describe rates and risk factors of depression and suicidal ideation in adolescents seen at a pediatric specialty clinic and examine changes during COVID-19. STUDY DESIGN: Retrospective database review. METHODS: Outpatient pediatric otolaryngology clinic encounters of patients aged 12-19 years at a tertiary academic medical center were identified from October 2018 to July 2020. Demographic characteristics, ICD-10 primary diagnosis, Patient Health Questionnaire (PHQ)-2 score, and PHQ-9 score (if administered) were obtained. Multivariable regression examined risk factors for PHQ-9 administration, PHQ-9 scores ≥10, and suicidal ideation. Patient characteristics and PHQ scores were compared before and after March 23, 2020 (California COVID-19 Stay-at-Home order). RESULTS: Three thousand six hundred nine encounters with PHQ-2 data were identified. Of these, 223 (6.2%) scored ≥3 and underwent PHQ-9 assessment, of which 121 (3.4% of 3,609) scored ≥10 on the PHQ-9 and 53 (1.5%) endorsed suicidal ideation. Factors associated with PHQ-9 administration were female gender (odds ratio [OR] 1.58, P = .001), obesity (OR 1.48, P = .043), and neck mass/neoplasm/cancer diagnosis (OR 1.99, P = .013). Female gender was also associated with suicidality (OR 2.47, P = .008). Comparison of pre-COVID-19 versus during COVID-19 showed no differences in depression or suicidality. However, subgroup analysis revealed some significant findings. CONCLUSIONS: We demonstrate substantial prevalence of positive depression screening and suicidal ideation among adolescent pediatric otolaryngology clinic encounters. Depression rates were similar to pre-COVID-19 and during COVID-19, yet barriers to screening during this time were substantial. Pediatric specialty providers must remain vigilant for mental health issues in their patients. LEVEL OF EVIDENCE: 3 Laryngoscope, 132:1104-1111, 2022.

Delayed Facial Nerve Palsy Following Resection of Vestibular Schwannoma: Clinical and Surgical Characteristics.

OBJECTIVE: Analyze delayed facial nerve palsy (DFNP) following resection of vestibular schwannoma (VS) to describe distinct characteristics and facial nerve (FN) functional course. STUDY DESIGN: Prospective cohort with retrospective review. SETTING: Academic medical center. PATIENTS: Consecutive patients undergoing VS resection 11/2017 to 08/2020. Exclusion criteria: preoperative House-Brackmann (HB) ≥ III, postoperative HB ≥ III without delayed palsy, <30 days follow-up. INTERVENTIONS: VS resection with intraoperative electromyographic monitoring. MAIN OUTCOME MEASURES: FN outcomes utilizing the HB scale; comparison between patients with DFNP (deterioration greater than one HB grade 24 hours to 30 days postoperatively) vs. those with HBI-II throughout. RESULTS: Two hundred eighty-eight patients met criteria: mean age 47.6 years, 36.1% male; 24.0% middle cranial fossa, 28.5% retrosigmoid, 47.6% translabyrinthine. DFNP occurred in 31 (10.8%) patients with average time to onset of 8.1 days. Of these, 22 (71.0%) recovered HBI-II and 3 (9.7%) recovered HBIII. Patients who experienced DFNP, on average, had larger maximum tumor diameter (23.4 vs. 18.7 mm, p = 0.014), lower rate of gross-total resection (54.8% vs. 75.5%, p = 0.014), and lower rate of ≥100 µV FN response to 0.05 mA stimulus intraoperatively (80.6% vs. 94.9%, p = 0.002). Compared to overall incidence of DFNP, translabyrinthine approach demonstrated higher incidence (15.3%, p = 0.017) while retrosigmoid lower (3.7%, p = 0.014). In multivariable logistic regression, patients with FN response ≥100 µV to 0.05 mA stimulus were 72.0% less likely to develop DFNP (p = 0.021). CONCLUSIONS: Intraoperative electromyographic facial nerve response, tumor size, surgical approach, and extent of resection may play a role in development of DFNP following resection of VS. Most patients who develop DFNP recover near-normal function.

Dispersed Bone Spicules as a Cause of Postoperative Headache after Retrosigmoid Vestibular Schwannoma Surgery: A Myth?

Objectives Dispersion of bone dust in the posterior fossa during retrosigmoid craniectomy for vestibular schwannoma (VS) resection could be a source of meningeal irritation and lead to development of persistent postoperative headaches (POH). We aim to determine risk factors, including whether the presence of bone spicules that influence POH after retrosigmoid VS resection. Design Present study is a retrospective case series. Setting The study was conducted at a tertiary skull-base referral center. Participants Adult patients undergoing VS resection via a retrosigmoid approach between November 2017 and February 2020 were included for this study. Main Outcome Measures Development of POH lasting ≥ 3 months is the primary outcome of this study. Results Of 64 patients undergoing surgery, 49 had complete data (mean age, 49 years; 53% female). Mean follow-up time was 2.4 years. At latest follow up, 16 (33%) had no headaches, 14 (29%) experienced headaches lasting <3 months, 19 (39%) reported POH lasting ≥3 months. Twenty-seven (55%) patients had posterior fossa bone spicules detectable on postoperative computed tomography (CT). Age, gender, body mass index, length of stay, tumor diameter, size of craniectomy, the presence of bone spicules, or the amount of posterior petrous temporal bone removed from drilling did not differ significantly between patients with POH and those without. On multivariate logistic regression, patients with POH were less likely to have preoperative brainstem compression by the tumor (odds ratio [OR] = 0.21, p = 0.028) and more likely to have higher opioid requirements during hospitalization (OR = 1.023, p = 0.045). Conclusion The presence of bone spicules in the posterior fossa on postoperative CT did not contribute to headaches following retrosigmoid craniectomy approach for VS resection.

Novel Implementation of Virtual Interviews for Otolaryngology Resident Selection: Reflections Relevant to the COVID-19 Era.

To address financial and scheduling conflicts associated with residency interviews for otolaryngology candidates, our residency program implemented virtual interviews as an alternative to the traditional in-person format for our visiting subinterns during the 2018-2019 and 2019-2020 interview cycles. Applicants then completed an anonymous survey about their interview experience. We found that, overall, positive attitudes toward virtual interviews increased among 2019-2020 candidates as compared with the year prior. Our results demonstrated an average cost savings per interview of $500 to $1000 when virtual technology was utilized. Based on feedback, improvements may be considered regarding eye contact, minimizing distractions, and providing the option to extend the interview length. Our experience provides a preliminary framework for transitioning to virtual interviews in the upcoming 2020-2021 otolaryngology residency selection process during the COVID-19 era, as well as for future studies assessing the utility of this method and its impact on overall match statistics.

Clinical Predictors of Facial Nerve Outcomes After Surgical Resection of Vestibular Schwannoma.

OBJECTIVE: To identify clinical predictors of facial nerve (FN) outcomes after microsurgical resection of vestibular schwannoma (VS). STUDY DESIGN: Prospective cohort study. SETTING: Academic medical center. METHODS: Consecutive patients undergoing VS resection from November 2017 to October 2019 were included. FN function was evaluated with the House-Brackmann (HB) scale and stratified into good (HB I-II) and poor (HB III-VI) function. Analyses included descriptive statistics, correlation, and logistic regression. RESULTS: Of 256 patients who met criteria (mean age, 47.7 years; 62.5% female), 227 (88.7%) achieved good FN function postoperatively and 238 (93.0%) at latest follow-up (mean, 154.8 days). Operative approaches consisted of translabyrinthine (50.8%), retrosigmoid (25.0%), and middle fossa craniotomies (24.2%). Extent of resection was decided intraoperatively, and gross or near total resection was accomplished in 237 (92.6%) cases. Postoperative HB grade correlated with latest HB grade (0.615, P < .001). Factors associated with good postoperative FN function included small tumor size (≤15 mm; odds ratio [OR], 2.425; P = .042), gross or near total resection (OR, 3.170; P = .041), and ≥100-µV intraoperative FN electromyographic response to a 0.05-mA stimulus (OR, 22.242; P < .001). Factors associated with good FN function at latest follow-up included gross total resection (OR, 7.764; P = .003) and ≥100-µV FN electromyographic response (OR, 8.518; P < .001), accounting for surgical approach and tumor size. CONCLUSION: Microsurgical resection of VS can be accomplished with excellent FN outcomes. Gross total resection and ≥100-µV intraoperative FN electromyographic response predicted excellent FN outcomes. Immediate postoperative FN function is a prognosticator of long-term FN function.

Student Perspectives on Remote Medical Education in Clinical Core Clerkships During the COVID-19 Pandemic.

PURPOSE: To assess student perceptions of remote learning curricula implemented by clinical clerkships at a single US medical school during the COVID-19 pandemic. METHOD: Students enrolled in core clinical clerkships at the UC San Diego School of Medicine from March to April 2020 were sent an anonymous online survey, assessing components of remote learning curricula via quantitative rating and free-response questions. RESULTS: Of 132 students enrolled, 96 (73%) completed the survey. Online question banks, remote progress reviews, and telehealth sessions were rated as the most valuable resources, while textbooks were rated least valuable. Most students felt that the number of resources was adequate (69/94, 74%), the quantity of required content was appropriate (77/93, 83%), and there was a good balance of rigidity versus flexibility in the schedule (81/94, 86%). Most students felt "prepared" or "somewhat prepared" for the shelf examination (61/91, 67%) and for the next year of medical training (73/94, 78%). In narrative reflections, students valued the flexibility afforded by remote curricula but desired some weekly structure. Students enjoyed expanded access to learning resources and participating in interactive remote sessions. Students expressed anxiety about the pandemic and uncertainty regarding medical education, but transparent communication from clerkship directors helped assuage these concerns. CONCLUSIONS: Student participation in direct patient care is fundamental to medical school core clerkships and was negatively impacted by the COVID-19 pandemic. Strategic incorporation of select remote learning components into clinical clerkships may permit a favorable student experience even when opportunities for on-site participation are limited.

Association of subjective olfactory dysfunction and 12-item odor identification testing in ambulatory COVID-19 patients.

BACKGROUND: Acute loss of smell and taste are well-recognized symptoms of coronavirus disease 2019 (COVID-19), yet the correlation between self-reported and psychophysical olfactory function remains unclear. Understanding the reliability of self-reported smell loss in ambulatory cases can assess the utility of this screening measure. METHODS: A prospective, longitudinal study evaluating patient-reported and measured olfactory function using the validated 12-item Brief Smell Identification Test (BSIT) was conducted on adult outpatients with COVID-19. Patient-reported olfaction scores using a visual analog scale (VAS) were obtained at baseline, time of COVID-19 testing, and time of BSIT completion. Linear associations between VAS and BSIT were evaluated using Spearman's correlation coefficient and the sensitivity, specificity, and accuracy of VAS scores were calculated. Logistic regression identified characteristics associated with accurate assessment of olfactory function. RESULTS: A total of 81 polymerase chain reaction (PCR)-confirmed COVID-19 positive subjects, of whom 54 self-reported smell loss, were prospectively recruited ≤5 days from diagnosis date between May 8, 2020, and July 8, 2020. Self-reported smell loss had good discriminative ability in identifying abnormal BSIT (area under receiver operating curve [AUC] 0.82, 95% confidence interval [CI], 0.71 to 0.92). A VAS <5 demonstrated sensitivity of 0.62 and specificity of 0.94 for predicting hyposmia (BSIT ≤8) with accuracy of 82.7%, whereas a VAS <9 had highest sensitivity at 0.86. Moderate bivariate linear associations were found between VAS and BSIT scores (rs = 0.59, p < 0.001). CONCLUSION: Self-reported olfactory loss associated with COVID-19 has a strong ability to predict abnormal olfactory function though the 2 measures are moderately correlated. Subjective olfactory assessment is useful in screening olfactory dysfunction at early disease time points when psychophysical testing cannot be conducted.
