RESUMEN
Infratemporal fossa (ITF) tumors are rare in children and may present with a variety of symptoms. Teratomas are neoplasms derived from the 3 germ layers and approximately 6% to 10% are within the head and neck. Our study discusses one of the first reported cases of teratoma in the ITF in a pediatric patient. A 3-year-old girl presents with 2 years of recurrent monthly left periorbital swelling accompanied by fevers, skin discoloration, and pain. Prior episodes were treated with antibiotics with incomplete resolution. Imaging revealed a cystic lesion centered in the ITF. She was taken for endoscopic endonasal biopsy of the lesion and had no complications. Pathology revealed a mature teratoma composed primarily of pancreatic tissue. Providers should consider masses such as teratoma in the differential for ITF tumors and periorbital edema unresponsive to typical treatment.
RESUMEN
BACKGROUND: With modern treatment paradigms, olfactory neuroblastoma (ONB) has favorable overall survival (OS); however, the incidence of recurrence remains high. The primary aims of this study were to delineate the prognosis of recurrence of ONB and explore how recurrence subsites are associated with OS, disease-specific survival (DSS), and further recurrence. METHODS: A retrospective chart review of ONB cases from nine academic centers between 2005 and 2021 was completed. Tumor characteristics, recurrence subsites, timelines to recurrence, additional recurrences, and survival estimates were determined using descriptive and time-to-event analyses. RESULTS: A final cohort of 233 patients was identified, with 70 (30.0%) patients recurring within 50.4 (standard deviation ±40.9) months of diagnosis on average, consisting of local (50%), neck (36%), intracranial (9%), and distant (6%) recurrence. Compared with subjects without recurrence, patients with recurrence had significantly different primary American Joint Committee on Cancer T stage (p < 0.001), overall stage (p < 0.001), and modified Kadish scores (p < 0.001). Histopathology identified that dural involvement and positive margins were significantly greater in recurrent cases. First recurrence was significantly associated with worse 5-year DSS (hazard ratio = 5.62; p = 0.003), and subjects with neck or local recurrence had a significantly better DSS compared to intracranial or distant recurrence. CONCLUSIONS: Recurrent cases of ONB have significantly different stages and preoperative imaging factors. Patients with local or neck recurrence, however, have better DSS than those with intracranial or distant recurrence, independent of initial tumor stage or Hyams grade. Identifying specific factors that confer an increased risk of recurrence and DSS is important for patient counseling in addition to surveillance planning.
RESUMEN
Importance: Current olfactory neuroblastoma (ONB) staging systems inadequately delineate locally advanced tumors, do not incorporate tumor grade, and poorly estimate survival and recurrence. Objective: The primary aims of this study were to (1) examine the clinical covariates associated with survival and recurrence of ONB in a modern-era multicenter cohort and (2) incorporate Hyams tumor grade into existing staging systems to assess its ability to estimate survival and recurrence. Design, Setting, and Participants: This retrospective, multicenter, case-control study included patients with ONB who underwent treatment between January 1, 2005, and December 31, 2021, at 9 North American academic medical centers. Intervention: Standard-of-care ONB treatment. Main Outcome and Measures: The main outcomes were overall survival (OS), disease-free survival (DFS), and disease-specific survival (DSS) as C statistics for model prediction. Results: A total of 256 patients with ONB (mean [SD] age, 52.0 [15.6] years; 115 female [44.9%]; 141 male [55.1%]) were included. The 5-year rate for OS was 83.5% (95% CI, 78.3%-89.1%); for DFS, 70.8% (95% CI, 64.3%-78.0%); and for DSS, 94.1% (95% CI, 90.5%-97.8%). On multivariable analysis, age, American Joint Committee on Cancer (AJCC) stage, involvement of bilateral maxillary sinuses, and positive margins were associated with OS. Only AJCC stage was associated with DFS. Only N stage was associated with DSS. When assessing the ability of staging systems to estimate OS, the best-performing model was the novel modification of the Dulguerov system (C statistic, 0.66; 95% CI, 0.59-0.76), and the Kadish system performed most poorly (C statistic, 0.57; 95% CI, 0.50-0.63). Regarding estimation of DFS, the modified Kadish system performed most poorly (C statistic, 0.55; 95% CI, 0.51-0.66), while the novel modification of the AJCC system performed the best (C statistic, 0.70; 95% CI, 0.66-0.80). Regarding estimation of DSS, the modified Kadish system was the best-performing model (C statistic, 0.79; 95% CI, 0.70-0.94), and the unmodified Kadish performed the worst (C statistic, 0.56; 95% CI, 0.51-0.68). The ability for novel ONB staging systems to estimate disease progression across stages was also assessed. In the novel Kadish staging system, patients with stage VI disease were approximately 7 times as likely to experience disease progression as patients with stage I disease (hazard ratio [HR], 6.84; 95% CI, 1.60-29.20). Results were similar for the novel modified Kadish system (HR, 8.99; 95% CI, 1.62-49.85) and the novel Dulguerov system (HR, 6.86; 95% CI, 2.74-17.18). Conclusions and Relevance: The study findings indicate that 5-year OS for ONB is favorable and that incorporation of Hyams grade into traditional ONB staging systems is associated with improved estimation of disease progression.

INTRODUCTION: The persistent lack of racial and ethnic diversity within the field of otolaryngology calls for an analysis of potential bias within the residency application system. Letters of recommendation (LORs) and personal statements (PSs) are the most important subjective application constituents. This subjectivity predisposes these components to implicit bias. In applications to various surgical subspecialties, prior linguistic studies assessing bias in reviews of LOR show race-based differences. Thus far, racial and ethnic linguistic differences in LORs for otolaryngology applicants have not been analyzed in the literature. METHODS: LORs and PSs were abstracted from otolaryngology - head and neck surgery applications in the Electronic Residency Application Service for the 2019-20 and 2020-21 application cycles. Linguistic Inquiry and Word Count 2015 was used for quantitative analysis of emotional, cognitive, and structural components of written text. RESULTS: Race-pair analysis of the 2019-2021 application cycles revealed higher mean "teaching" scores for LORs for Asian, black, Hispanic, and white applicants when compared to applicants who self-identified as Other. White applicants had lower scores for the terms "research" and "analytic" when compared to Asian and black applicants, respectively. Analysis of PSs revealed greater scores for an "authentic" writing style for white versus Asian applicants. White applicants were found to have higher scores for "tone" compared to black applicants. CONCLUSION: Minor racial and ethnic language differences exist in both LORs and PSs. A statistically significant difference was observed among LORs, with the "teaching" term used more frequently for Asian, black, Hispanic, and white applicants compared to self-identified Other individuals. For PSs, statistically significant differences were observed among white applicants, who wrote about themselves using more "authentic" language when compared with Asian applicants and who also had higher scores for "tone" compared to black applicants. Although these differences were statistically significant, the practical impact of the variances is likely small.

BACKGROUND: Traditional management of olfactory neuroblastoma (ONB) includes margin-negative resection with removal of cribriform plate, dura, and olfactory bulb, regardless of intracranial disease. This approach may be overtreating certain patients. Our investigation examines risk factors associated with occult intracranial disease to optimize therapeutic outcomes. METHODS: This retrospective, multi-institutional cohort study examined clinical covariates associated with occult intracranial involvement. Patient demographics, staging, Hyam's grade, and pathologic involvement of dura, olfactory bulb/tract, and brain were collected. Diagnostic imaging was reviewed. Positive and negative predictive value (NPV) were estimated along with effect size estimates. Cox hazard regression examined associations with overall survival (OS) and disease-free survival (DFS). RESULTS: A total of 224 subjects with new diagnoses of ONB (2005-2021) were identified. Skull base bone involvement on computed tomography (CT) had the highest NPV for pathologic dura (88.0%), olfactory bulb (88%), and brain involvement (97.3%). Hyam's grade category was significantly associated with dural involvement (φC = 0.26; 95% confidence interval [CI]: 0.16, 0.42). Subjects without radiologic skull base involvement (n = 66) had pathologic positivity of 12.1%. Within this subgroup, Hyam's grade was clinically significant for dural positivity (φ = 0.34; 95% CI: -0.12, 0.71) with 28.6% involvement in high grade tumors. Neither clinical nor pathologic positivity of intracranial structures were associated with significantly different OS or DFS. CONCLUSIONS: Both CT and magnetic resonance imaging (MRI) had reasonably good NPV for involvement of dura and olfactory bulb. Higher Hyam's grade was associated with dural involvement. Patients with low-grade tumors not involving the skull base may be suitable for avoiding skull base resection; however, further investigation is warranted.

Background: The emergence of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has resulted in an unprecedented global pandemic. Most infected patients are either asymptomatic or have mild upper respiratory infection symptoms. However, life-threatening sequelae have been observed. In this report, we reviewed nine cases of patients with severe complications from sinonasal disease in the setting of acute SARS-CoV-2 infection. Methods: IRB approval was obtained prior to study initiation. A retrospective chart review was performed of patients admitted to a tertiary hospital with complex sinonasal symptoms that required otolaryngologic evaluation and management in the setting of concomitant SARS-CoV-2 infection. Results: Nine patients, ranging from ages 3 to 71 years, with sinonasal disease and simultaneous SARS-CoV-2 infection were identified. Initial presentations ranged from asymptomatic infection to mild/moderate disease (nasal obstruction, cough) or more severe sequelae including epistaxis, proptosis, or neurologic changes. SARS-CoV-2 tests were positive from one to 12 days after symptom onset, with three patients receiving SARS-CoV-2-directed treatment. Complex disease presentations included bilateral orbital abscesses, suppurative intracranial infection, cavernous sinus thrombosis with epidural abscess, systemic hematogenous spread with abscess development in four distinct anatomic locations, and hemorrhagic benign adenoidal tissue. Eight of nine patients (88.8%) required operative intervention. Patients with abscesses also required prolonged, culture-directed antibiotic courses. Conclusion: Though most SARS-CoV-2 infections are asymptomatic and/or self-limited, there is significant morbidity and mortality in patients with severe disease sequela as outlined in our reported cases. This suggests early identification and treatment of sinonasal disease in this patient population is critical to minimizing poor outcomes. Further research on the pathophysiology of these atypical presentations is needed. Level of Evidence: 4 (Case Series).
RESUMEN
OPINION STATEMENT: The role of induction chemotherapy in sinonasal cancers is promising; however, prospective studies with higher grades of evidence are needed. With the currently available literature, the authors would advocate for the use of induction chemotherapy (IC) in locally advanced sinonasal squamous cell carcinoma (T3-T4) for organ preservation and potentially for improved survival outcomes. In sinonasal undifferentiated carcinoma (SNUC), IC should be considered in all patients given its tendency for aggressive invasion and poor outcomes. In SNUC, response to IC may direct the modality of definitive treatment to follow. In responders (partial or complete), chemoradiation therapy should be strongly considered. In non-responders or in those with progression of disease, surgical therapy is favored. For esthesioneuroblastoma, surgical resection with negative margins and adjuvant radiation therapy remains the gold standard. However, IC may be considered for locally advanced disease especially with orbital invasion or in recurrent/distant disease. There is no definite indication for IC in sinonasal adenoid cystic carcinoma or sinonasal adenocarcinoma. Recommendations are summarized in Table 1.

Objective: As of January 2022, USMLE Step 1 scores are reported as pass/fail. Historically, Step 1 scores have been a critical component of residency applications, representing one of the few metrics standardized across all applicants independent of the school they attended. In competitive specialties, such as otolaryngology, programs routinely get 100+ applicants for each residency spot and use Step 1 as a screening tool. This study seeks to assess quantifiable metrics in the application that highly competitive residency programs could use for screening in place of Step 1 scores. Methods: Otolaryngology applications to an academic medical center for the 2019-20 and 2020-21 ERAS cycles were reviewed. Board scores and quantitative research data were extracted. The relationships between Step 1 score and the other metrics were examined by computing Pearson's correlation coefficients and building regression models. Similar analyses were done separately for three different score tiers defined by Step 1 cutoffs at 220 points and 250 points. Results: Step 2 score was the only variable that had meaningful correlation with Step 1 score (R = .67, p < 2.2e-16). No other objective metric such as journal articles, posters, or oral presentations correlated with Step 1 scores. Conclusion: Step 1 scores were moderately correlated with Step 2 scores; however, using a Step 2 cutoff instead of a Step 1 cutoff would identify a different cohort of applicants for interview. No other quantifiable application metric had a positive correlation. In future match cycles, highly competitive residency programs will need to adopt new methods to screen candidates.Level of Evidence: Level 3.
RESUMEN
Objective: Application for otolaryngology residency is highly competitive, with letters of recommendation (LORs) and applicant personal statements (PSs) representing important components of the application process. However, their inherently subjective nature predisposes them to potential implicit bias. Otolaryngology has historically been predominated by male physicians and while implicit sex bias has been demonstrated in LORs for application to residency of multiple specialties, data is limited for otolaryngology. Methods: LORs and PSs for all otolaryngology applicants to an academic medical center during the 2019-20 and 2020-21 cycles were abstracted. Quantitative analysis was performed using Linguistic Inquiry and Word Count 2015 (LIWC2015), a validated software application designed to analyze various emotional, cognitive, and structural components of written text. Results: LORs written for females were found to be written from a perspective of higher expertise and confidence while LORs written for males were associated with a more honest, personal, and disclosing tone. Moreover, LORs written for female applicants were found to reference achievement and "grindstone" terminology more than those written for men. No differences were observed in any word category between PSs written by male and female applicants. Conclusion: Minor linguistic differences exist in multiple domains between LORs written for male and female applicants for otolaryngology residency. These tended to favor female applicants, with their letters demonstrating higher clout, achievement, and grindstone scores. This trend was unexpected in this historically predominantly male specialty. While differences were statistically significant, the overall difference in an entire letter of recommendation is likely subtle. Level of Evidence: 3.
RESUMEN
OBJECTIVES/HYPOTHESIS: Create an autonomous computational system to classify endoscopy findings. STUDY DESIGN: Computational analysis of vocal fold images at an academic, tertiary-care laryngology practice. METHODS: A series of normal and abnormal vocal fold images were obtained from the image database of an academic tertiary care laryngology practice. The benign images included normals, nodules, papilloma, polyps, and webs. A separate set of carcinoma and leukoplakia images comprised a single malignant-premalignant class. All images were classified with their existing labels. Images were randomly withheld from each class for testing. The remaining images were used to train and validate a neural network for classifying vocal fold lesions. Two classifiers were developed. A multiclass system classified the five categories of benign lesions. A separate analysis was performed using a binary classifier trained to distinguish malignant-premalignant from benign lesions. RESULTS: Precision ranged from 71.7% (polyps) to 89.7% (papilloma), and recall ranged from 70.0% (papilloma) to 88.0% (nodules) for the benign classifier. Overall accuracy for the benign classifier was 80.8%. The binary classifier correctly identified 92.0% of the malignant-premalignant lesions with an overall accuracy of 93.0%. CONCLUSIONS: Autonomous classification of endoscopic images with artificial intelligence technology is possible. Better network implementations and larger datasets will continue to improve classifier accuracy. A clinically useful optical cancer screening system may require a multimodality approach that incorporates nonvisual spectra. LEVEL OF EVIDENCE: NA Laryngoscope, 132:S1-S8, 2022.
