Endoscopic endonasal greater palatine artery cauterization at the incisive foramen for control of anterior epistaxis.

OBJECTIVES/HYPOTHESIS: To describe the anatomy of the incisive foramen and the transnasal endoscopic approach to the greater palatine artery at this foramen, and to evaluate the importance of the greater palatine artery as a cause of recurrent anterior epistaxis. STUDY DESIGN: Anatomical dissection, radiographic study, and prospective case series. SETTING: Academic Medical Center. METHODS: Sixty-nine computed tomography scans were reviewed, and measurements were made of the incisive foramina's distance to the anterior nasal spine and subnasale. Twenty-two cadavers had sagittal split craniotomies performed prior to the measurements. The distance from the anterior nasal spine to the incisive foramen was documented. We also present an illustrative case series of patients who underwent endoscopic cautery of the greater palatine artery at the incisive foramen. RESULTS: Radiographic review of the incisive foramen revealed a mean anterior nasal spine to incisive foramen distance on the right and left of 7.9 and 8.1 mm, respectively. The mean distance from the subnasale to incisive foramen on the right and left were 24.7 and 24.9 mm, respectively. CONCLUSIONS: Endoscopic cauterization of the greater palatine artery at the incisive foramen is a safe and effective method to control recurrent anterior epistaxis. The incisive foramen can be predictively found within 1 cm of the anterior nasal spine. Our case series corroborates the above. LEVEL OF EVIDENCE: 4. Laryngoscope, 126:1033-1038, 2016.

Predictability of cochlear implant outcome in families.

OBJECTIVES: The purpose of this study is to determine if the performance of the first implanted member of a family predicts the performance of subsequently implanted family members. STUDY DESIGN: Retrospective chart review. METHODS: Seventy-one cochlear implant recipients, each belonging to a family with two or more implanted members, were the subjects of this study. Routine audiometric measurements and age-appropriate speech perception tests were performed pre- and postoperatively. In addition, length of deafness, age at implantation, etiology, and length of device usage were correlated to outcome. RESULTS: All implant recipients within a family showed improvement postimplantation, and the predictive component between family members was strong. Presence of GJB2 mutations and greater age at implantation were predictive of poorer rehabilitative outcome, while length of device usage was associated with improved speech perception scores. CONCLUSIONS: On average, if the first implanted family member performs well with a cochlear implant, those following will do well; however, GJB2-related deafness and increased age at implantation are associated with poorer outcome. These findings have important implications for members of families considering cochlear implantation.
