Importance/UNASSIGNED:Genomic classifiers were developed to better guide clinicians in the treatment of indeterminate thyroid nodules (ITNs). To our knowledge, whether there is variation in the diagnostic accuracy of these tests depending on ITN size has not been previously studied. Objective/UNASSIGNED:To analyze the diagnostic performance of a genomic classifier in relation to ITN size. Design, Setting, and Participants/UNASSIGNED:A case series study with medical records review was conducted including all patients with a cytologic diagnosis of ITN managed with genomic classifier testing and surgery from January 2015 to December 2018 at NYU Langone Health. Demographics, ITN characteristics, genomic profiles, treatment, and final pathologic findings were recorded. Data analysis was conducted from March to April 2021. Main Outcomes and Measures/UNASSIGNED:The primary aim was to assess the positive predictive value (PPV), negative predictive value (NPV), sensitivity, and specificity of a genomic classifier test (ThyroSeq) in relation to ITN size (<2, 2-4, and >4 cm). The secondary aim was to investigate the risk of cancer associated with genetic signatures. Results/UNASSIGNED:Of the 212 patients with 218 ITNs, 158 (74.5%) were women; median (SD) age was 49 (15.6) years. Genomic classifier results were positive in 173 ITNs (79.4%) treated with surgery. In this group of 173 positive ITNs, 46 (26.6%) were malignant on final pathologic testing. Overall, the observed cancer prevalence in the population was 23.9% (52 ITNs). In 45 ITNs that underwent surgery despite a negative genomic classifier interpretation, 6 (13.3%) were malignant. The PPV of a positive test was 27% and the NPV was 87%. The PPV and NPV findings improved as the ITN size increased (<2 cm [n = 98]: PPV, 25%; NPV, 79% vs >4 cm [n = 33]: PPV, 50%; NPV, 89%). Test specificity was higher in larger ITNs (<2 cm: 15% vs >4 cm: 40%; P = .01). Isolated RAS sequence variations were the most common variant identified in malignant nodules (11 [21.1%] of all ITNs), followed by BRAF variants (7 [13.5%] of all ITNs). Conclusions and Relevance/UNASSIGNED:In this case series, the performance of the ThyroSeq test improved for larger ITNs. The risk of cancer in large ITNs with negative test results was low. These data suggest that, in genomic classifier-negative ITNs larger than 4 cm, initial management of thyroid lobectomy may be sufficient.

OBJECTIVE:To present a rare case of a middle ear capillary hemangioma in an adult. PATIENT/METHODS:A 31-year-old woman with a 6-month history of left ear fullness, pressure, tinnitus, and progressive hearing loss. INTERVENTION/METHODS:Endoscopic laser-assisted resection. MAIN OUTCOME MEASURES/METHODS:Clinical, radiographic, and histopathological findings of a capillary hemangioma. RESULTS:Otoscopy revealed an erythematous and slightly pulsating multilobulated middle ear retrotympanic mass. Her audiogram demonstrated a left-sided mixed hearing loss with air-conduction thresholds in the severe-to-profound range. Computed tomography (CT) imaging was significant for total opacification of the left middle ear and mastoid air cells. She underwent a combined endoscopic transcanal and transmastoid excision of the mass with ossicular chain reconstruction. A KTP laser was used to ablate and shrink down the periphery of the lesion. Pathology of the specimen was consistent with a capillary hemangioma. The patient's pulsatile tinnitus and spontaneous vertigo resolved postoperatively. CONCLUSIONS:Capillary hemangiomas are an uncommon cause of vascular middle ear lesions in adults and typically present with symptoms of aural fullness, pulsatile tinnitus, conductive hearing loss, otalgia, and vertigo. Surgery resection provides definitive treatment and the use of laser ablation techniques can allow for hemostasis and excellent visualization.

Gaining, improving, and maintaining nasal tip projection is one of the most essential elements of successful endonasal rhinoplasty. For years the hallmark of inadequate nasal tip projection following rhinoplasty has been the Polly beak deformity. Early rhinoplasty technique consisted of intracartilaginous excision of the cephalic margin of the lower lateral cartilages, cartilage and bony hump reduction, and osteotomies. Some of these simple rhinoplasties still look good decades later, however, many are conspicuous in their lack of nasal tip projection. The reason for this inconsistency in rhinoplasty results was the surgeon's inattention to the structural integrity and anatomical position of the LLC. The senior author uses a combination of suture, strut, and cartilage grafting techniques to achieve ideal projection in a manor tailored to each patient's unique anatomic needs.

Movement disorder emergencies of the aerodigestive tract are dramatic and often life threatening. With appropriate timely evaluation and intervention, most patients can be effectively managed and major morbidity avoided. This chapter provides a comprehensive review of both the causes and appropriate treatment of breathing disturbances secondary to primary disorders and iatrogenic causes, as well as swallowing emergencies. Additionally, basic physiology, anatomy, and various methods for assessment of the upper aerodigestive tract are reviewed. Specific disorders that are addressed include the following: spasmodic dysphonia, adductor laryngeal breathing dystonia, Shy-Drager abductor weakness, drug-induced tardive dystonia, oromandibulolingual dystonia, multiple system atrophy, multiple sclerosis, amyotrophic lateral sclerosis, Parkinson's disease, Huntington's disease, and palatal myoclonus.

Successful tracheal reconstruction remains a challenging task for the reconstructive surgeon. A variety of techniques have been previously employed, using both autografts and allografts. The authors present a novel method for tracheal reconstruction utilizing a prelaminated fascial flap in conjunction with a bioabsorbable scaffold. Laryngoscope, 2021.

BACKGROUND:Nephrolithiasis is a sequela of primary hyperparathyroidism and an indication for parathyroidectomy. The prevalence of primary hyperparathyroidism in patients with nephrolithiasis is 3% to 5%; however, recent studies suggest that many hypercalcemic patients with nephrolithiasis never undergo workup for primary hyperparathyroidism. Our goal is to evaluate primary hyperparathyroidism screening rates at a tertiary academic health institution and identify opportunities to increase referral rates in patients presenting with nephrolithiasis. METHODS:We retrospectively reviewed 15,725 patients across an academic health system who presented with nephrolithiasis between 2012 and 2020. Calcium levels measured within 6 months of presentation were identified, and those with hypercalcemia (≥10.3 mg/dL) were reviewed if parathyroid hormone levels were measured. Patients with primary hyperparathyroidism were evaluated to see if they were referred to a specialist for treatment. RESULTS:Of 15,725 patients presenting with nephrolithiasis, 12,420 (79%) had calcium levels measured; 630 patients (4.0%) were hypercalcemic, and 207 (33%) had parathyroid hormone levels measured. Patients were more likely to have parathyroid hormone levels sent if they were older, had higher calcium levels, or presented to an outpatient clinic (P = .028, P = .002, P < .001). We identified 89 patients (0.6%) with primary hyperparathyroidism, of which only 35 (39%) were referred for treatment. CONCLUSION/CONCLUSIONS:The proportion of patients presenting with nephrolithiasis ultimately diagnosed with primary hyperparathyroidism was significantly lower than others have reported. Additionally, a substantial number of patients with nephrolithiasis did not have calcium and/or parathyroid hormone levels measured. These missed opportunities for diagnosis are critical as early definitive management of primary hyperparathyroidism can prevent recurrent nephrolithiasis and other primary hyperparathyroidism-related end organ effects.

OBJECTIVES/OBJECTIVE:Pain localized to the thyrohyoid region may be due to neuralgia of the superior laryngeal nerve (SLN), inflammation of the thyrohyoid complex, or a voice disorder. We present outcomes of treatment of paralaryngeal pain and odynophonia with SLN block. STUDY DESIGN/METHODS:Retrospective Review. METHODS:A retrospective chart review of patients undergoing in-office SLN block for paralaryngeal pain between 2015 and 2018 at two tertiary care centers was conducted. Patient demographics, indications, and response to treatment were analyzed. RESULTS:Thirty-eight patients underwent blockade of the internal branch of the SLN for paralaryngeal pain, with 10 excluded for incomplete medical records. Eighty-two percent (23/28) reported an improvement in their symptoms. Patients underwent an average of 2.5 blocks (SD = 1.88, range 1-8), with 10 patients (36%) undergoing a single procedure. Of the 18 patients who underwent multiple blocks, nine had eventual cessation of symptoms (50%) compared to resolution in 6/10 undergoing a single injection. Eleven patients (39%) noted odynophonia related to vocal effort, and all of these patients had improvement in or resolution of their symptoms and were more likely to improve compared to those without odynophonia (P = .006). Of the four patients who had a vocal process granuloma (VPG) at presentation, three had complete resolution of the lesion at follow-up. CONCLUSION/CONCLUSIONS:In-office SLN block is effective in the treatment of paralaryngeal pain. It may be used as an adjunct in the treatment of vocal process granulomas, as well as voice disorders where odynophonia is a prominent symptom. LEVEL OF EVIDENCE/METHODS:4 Laryngoscope, 2021.

Male circumcision (MC) is one of the oldest surgical procedures still completed today. Medical indications for MC include phimosis, recurrent balanitis, cosmesis, and infection prevention. In this review, we mainly focus on the role of MC in the prevention of human immunodeficiency virus, human papillomavirus, herpes simplex virus, gonorrhea, chlamydia, chancroid, and syphilis, and the subsequent impact of these genitourinary infections on male fertility. Overall, many compelling data support that MC may play an essential role in both genitourinary infection prevention and male fertility.

OBJECTIVES/OBJECTIVE:The goals of this study were to 1) compare global protein expression in muscles of the larynx and hindlimb and 2) investigate differences in protein expression between aged and nonaged muscle using label-free global proteomic profiling methods. METHODS:Liquid chromatography-mass spectrometry (LC-MS/MS) analysis was performed on thyroarytenoid intrinsic laryngeal muscle and plantaris hindlimb muscle from 10 F344xBN F1 male rats (5 old and 5 young). Protein expression was compared and pathway enrichment analysis performed for each muscle type (larynx and limb) and age group (old and young muscle). RESULTS:Over 1,000 proteins were identified in common across both muscle types and age groups using LC-MS/MS analysis. Significant age-related differences were seen across 107 proteins in plantaris hindlimb and in 19 proteins in thyroarytenoid laryngeal muscle. Bioinformatic and enrichment analysis demonstrated protein differences between the hindlimb and larynx may relate to immune and stress redox responses and RNA repair. CONCLUSION/CONCLUSIONS:There are clear differences in protein expressions between the laryngeal and hindlimb skeletal muscles. Initial analysis suggests differences between the two muscle groups may relate to stress responses and repair mechanisms. Age-related changes in the thyroarytenoid appear to be less obvious than in the plantaris. Further in-depth study is needed to elucidate how aging affects protein expression in the laryngeal muscles.

OBJECTIVE:Despite the increase of women in surgical fields and resources toward advancing women, there is no corresponding increased representation of women in higher academic ranks and leadership. The following hypotheses are explored: 1) men and women build/maintain different relationship networks and 2) women are not similarly included within the organization and do not receive the same sponsorship as male counterparts. STUDY DESIGN/METHODS:Prospective observational study. METHODS:Three months of prospective, passive organizational network data of full-time faculty at an academic medical center were collected by analysis of deidentified internal email communication logs. Data were analyzed and strength of network relationships was assessed using algorithms measuring the tie, or connection, score. Data analysis was performed with standard statistical methods and multivariable regression models, comparing network relationships based on gender and academic rank. RESULTS:Among 345 full-time faculties from surgical departments, 45.2% were female Assistant Professors, but only 9.8% were female full Professors. Men had 55% more network relationships with other men than women had with men. Gender homophily was particularly pronounced at the higher academic ranks. Men compared to women in higher ranks had 157% more network relationships to other men in lower ranks. Multivariable regression models suggested direct association of these gender differences in relationships with more women in lower academic ranks. CONCLUSION/CONCLUSIONS:Higher academic rank can be predicted by male gender, tenure, and number of meaningful relationships. Women are underrepresented at the leadership level in surgical departments. Gender homophily is present in collaboration networks among academic surgeons and is associated with impeded female career advancement. LEVEL OF EVIDENCE/METHODS:2 Laryngoscope, 2021.
