Although other fall-related injuries have been characterized, little attention has been dedicated to facial trauma. To estimate the incidence of facial trauma among nursing home residents and detail mechanisms of injury, injury characteristics, and patient demographic data. The National Electronic Injury Surveillance System was used to calculate a weighted national incidence of facial trauma among individuals older than 60 years from a nationally representative collection of emergency departments from January 1, 2011, through December 31, 2015. Entries were screened for nursing home residents, and diagnosis, anatomical site, demographic data, and mechanism of injury were analyzed. There were 109 795 nursing home residents (median age, 84.1 years; interquartile range, 79-89 years; 71 466 women [65.1%]) who required emergency department care for facial trauma. ...

Recent studies have investigated the applicant criteria used by residency programs as part of the ranking process. However, to our knowledge, no studies have comprehensively investigated the role of geographic location in the match process. To evaluate geographic trends in the otolaryngology national residency match process. We conducted a cross-sectional examination of 56 otolaryngology residency programs including 810 residents to determine resident demographic information, including matriculated medical schools. The geographic locations of residency programs and the residents' matriculated medical schools were evaluated for trends. Residents' program locations were compared with the locations of their medical schools of matriculation, and the numbers of residents attending a program affiliated with their medical schools were also identified. Overall, 810 resident...

Levamisole-adulterated cocaine (LAC) exposure can result in neutropenia, thrombocytopenia, and vasculitis with a predilection for subsites of the face. The objective of this review is to increase awareness among otolaryngologists of the manifestations of LAC exposure. We present the case of a 33-year-old woman with a history of cocaine use, consulted for purpuric, necrotic lesions of the nose, cheeks, and ears, with accompanying leukopenia, thrombocytopenia, and positive antineutrophil cytoplasmic antibodies (ANCA). The effects of levamisole are immune mediated, with antibodies directed against neutrophils causing neutropenia, and vasculitis caused by antibody deposition or secondary to induction of antiphospholipid antibodies causing thrombosis. LAC exposure can be differentiate...

Predicting which patients are at high risk for developing DI can help direct services to ensure adequate care and follow-up. The objective of this study was to review our institution's experience with ETSS and determine which clinical/laboratory variables are associated with DI in this patient population. The authors wanted to see if there was an easily determined single value that would help predict which patients develop DI. This represents the largest North American series of this type. We retrospectively reviewed the charts of patients who had undergone ETSS for resection of sellar and parasellar pathology between 2006 and 2011. We examined patient and tumor characteristics and their relationship to postoperative DI. Out of 172 endoscopic transsphenoidal surgeries, there were 15 cases of transient DI (8.7%) and 14 cases of permanent DI (8.1%). Statistically significant predictors of postoperative DI (p < 0.05) included tumor volume and histopathology (Rathke's cleft cyst and craniopharyngioma). Significant indicators of development of DI were postoperative serum sodium, preoperative to postoperative change in sodium level, and urine output prior to administration of 1-deamino-8-D-arginine vasopressin. An increase in serum sodium of ≥2.5 mmol/L is a positive marker of development of DI with 80% specificity, and a postoperative serum sodium of ≥145 mmol/L is a positive indicator with 98% specificity. Identifying perioperative risk factors and objective indicators of DI after ETSS will help physicians care for patients postoperatively. In this large series, we demonstrated that there were multiple perioperative risk factors for the development of DI. These findings, which are consistent with other reports from microscopic surgical series, will help identify patients at risk for diabetes insipidus, aid in planning treatment algorithms, and increase vigilance in high risk patients.

Study Design Case series with chart review. Setting Tertiary care academic center. Subjects and Methods Medical records of all adult patients undergoing diagnostic DISE as part of their surgical evaluation were reviewed. Patients were included if they had undergone FNMM and had documented Friedman tongue position and tonsillar grade prior to DISE. Airway obstruction on both endoscopic procedures was described according to airway level and severity. Severe airway obstruction was defined as >75% collapse on endoscopy. Results Fifty-three patients were included in this study. Fiber-optic nasal endoscopy with Müller’s maneuver and DISE did not differ significantly regarding the presence of severe retropalatal airway collaps...

However, in select cases, this technique may involve unnecessary resection of sinonasal structures. In this study, we propose a modification of the EMLP, termed the modified subtotal-Lothrop procedure (MSLP), to access the anterior skull base and complex frontal sinus disease for which access to the bilateral frontal sinus posterior table is required. Methods A cadaveric dissection with photo documentation was performed at an academic medical center on four cadaver heads using standard endoscopic techniques to demonstrate the MSLP and its feasibility. Results The endoscopic MSLP allowed ample access for instrumentation in each of the dissections using a 30- or 70-degree endoscope. Adequate bilateral access to the posterior table of the frontal sinus was gained in all cases without the need for dissection of the contralateral f...
