RESUMO
OBJECTIVE: To determine radiologic preferences of practicing otolaryngologists regarding isolated nasal bone fractures. STUDY DESIGN: An 8-question survey on isolated nasal bone fractures was designed. SETTING: Surveys were sent to all otolaryngology residency program directors for distribution among residents and faculty. Additional surveys were distributed to private practice otolaryngology groups. RESULTS: 140 physicians responded to the survey. 57% of the respondents were practicing otolaryngologists (75% with 10+ years of experience), while 43% of respondents were residents-in-training. 56% of respondents treated 1-5 nasal bone fractures per month. 80% of all respondents reported imaging being performed prior to consultation. If imaging was obtained before consultation, plain films and computed tomography (CT) maxillofacial/sinus scans were the most frequent modalities. 33% of residents and 70% of practicing otolaryngologists report imaging as 'rarely' or 'never' helpful in guiding management. 42% of residents and 20% of practicing otolaryngologists report asking for imaging when it wasn't already obtained. Decreased use of radiography was associated with greater years in practice and higher frequency of fractures treated. CONCLUSIONS AND RELEVANCE: Otolaryngologists seldom request imaging to evaluate and treat isolated nasal bone fractures. When ordered, imaging is utilized more often among residents-in-training and non-otolaryngology consulting physicians. This study highlights an opportunity to educate primary care and emergency room providers as well as otolaryngology residents on the value of comprehensive physical exam over radiographic imaging in the work-up of isolated nasal fractures. In addition, widespread adoption of a "no x-ray policy" in this setting may result in better resource utilization.

BACKGROUND: The orbital complication rate during endoscopic sinus surgery (ESS) is <1%. Orbital fat exposure during ESS can herald orbital complications including orbital hematoma, extraocular muscle trauma, optic nerve injury, or blindness. The objective of this study was to evaluate the current consensus regarding diagnosis and management of orbital fat exposure during ESS. METHODS: A 24-point survey focused on orbital fat exposure during ESS was distributed to American Rhinologic Society members. Also, a retrospective review of 25 cases of orbital fat exposure drawn from the principal investigator's 30-year experience was performed. RESULTS: Over 10 000 surgical cases of the principal investigator were reviewed. Twenty-five patients had orbital fat exposure. Five developed minor complications while 2 were major (ie, temporary vision changes). Two hundred thirty-six surgeons responded to the survey; 93% had encountered orbital fat during ESS; 88% of surgeons identify orbital fat by either its appearance endoscopically or the "bulb press" test. Almost every responding surgeon will cautiously avoid further manipulation in the area of orbital fat exposure. Nearly half will immediately curtail the extent of surgery. Surgeons do not significantly change postoperative management. Considerations regarding observation in postanesthesia care unit, close follow-up, and strict nose blowing precautions are common. CONCLUSION: Orbital fat exposure during ESS is a rarely discussed, but clinically important. Orbital fat exposure can be a harbinger for major orbital complications that should be recognized by endoscopic appearance and confirmed with the bulb press test. Caution with "no further manipulation" of orbital fat is the guiding principle for intraoperative management, while postoperative management is generally expectant.Level 4 Evidence.

Repetitive mild traumatic brain injury (rmTBI) results in a myriad of symptoms, including vestibular impairment. The mechanisms underlying vestibular dysfunction in rmTBI patients remain poorly understood. Concomitantly, acute hypogonadism occurs following TBI and can persist chronically in many patients. Using a repetitive mild closed-head animal model of TBI, the role of testosterone on vestibular function was tested. Male Long Evans Hooded rats were randomly divided into sham or rmTBI groups. Significant vestibular deficits were observed both acutely and chronically in the rmTBI groups. Systemic testosterone was administered after the development of chronic vestibular dysfunction. rmTBI animals given testosterone showed improved vestibular function that was sustained for 175 days post-rmTBI. Significant vestibular neuronal cell loss was, however, observed in the rmTBI animals compared to Sham animals at 175 days post-rmTBI and testosterone treatment significantly improved vestibular neuronal survival. Taken together, these data demonstrate a critical restorative role of testosterone in vestibular function following rmTBI. This study has important clinical implications because it identifies testosterone treatment as a viable therapeutic strategy for the long-term recovery of vestibular function following TBI.

BACKGROUND: Hemangiopericytomas (HPCs) and solitary fibrous tumors (SFTs) are rare tumors of mesenchymal origin. Here, the authors present a rare case of anaplastic HPC in the jugular foramen (JF). The authors also conduct a systematic review of the literature to examine the current fund of knowledge on JF HPC/SFTs. METHODS: A systematic MEDLINE search was conducted using key words "hemangiopericytoma" OR "solitary fibrous tumor" AND "jugular foramen" OR "extracranial" OR "skull base." Clinicopathologic characteristics and outcomes of the present case were reviewed and compared with those in the literature. RESULTS: A 41-year-old male, who had undergone stereotactic radiation therapy 6 years ago for a presumed glomus jugulare tumor, presented to our institution with worsening dysphagia, hoarseness, persistent tongue weakness, and radiographic evidence of tumor progression. The patient underwent uncomplicated gross total resection with sacrifice of the infiltrated hypoglossal nerve. Histopathologic evaluation revealed anaplastic HPC/SFT (World Health Organization grade III). Review of the literature yielded 9 additional cases of JF HPC/SFT in 5 males (56%) and 4 females (44%), with a mean age of 49.6 years old. Patients commonly presented with pain (37.5%) and lower cranial nerve deficits (100%). Preoperative diagnoses included glomus jugulare (n = 2) or JF schwannomas (n = 3). All patients underwent microsurgical resection of the lesion, except for 1 who refused all treatment after diagnostic biopsy. CONCLUSION: The authors present the only reported case of anaplastic HPC of the JF. The illustrative case and those found on systematic review of the literature highlight the importance of tissue diagnosis and appropriate management.

BACKGROUND: Silicone stents are commonly employed to treat subglottic stenosis. A frequent complication is the tendency of stents to migrate. As such, various techniques to secure stents have been developed over the years, none of which have gained large popularity. We present a novel, low-cost, and easy-to-perform technique herein. OBJECTIVES: To describe a novel surgical technique to secure silicone stents and prevent migration for management of subglottic stenosis. MATERIALS AND METHODS: After standard excision and dilation of stenotic portions in the subglottic or trachea. A silicone stent is introduced in a standard fashion. To secure the stent, an 18-G needle loaded with braided suture is inserted through skin, trachea, and stent. Endoscopic visualization then permits the surgeon to grasp the suture with forceps. A separate transcutaneous puncture site is performed with an 18-G needle attached to a 10-cc syringe (plunger removed) and blue tip suction within the empty syringe, creating an airtight suctioning tool. The grasped suture is gently introduced into the eye of the needle and quickly travels into the 10-cc syringe with suction assist, leaving both extracorporeal ends of the suture to tie. RESULTS: This stitch has been employed on seven occasions on four patients. There have been no episodes of stent migration. A laboratory model found the 18-G needle and braided 3-0 suture performed optimally. CONCLUSIONS: We present a novel surgical technique to secure silicone stents in management subglottic or tracheal stenosis. LEVEL OF EVIDENCE: Level 4 Laryngoscope, 130:E346-E348, 2020.
