Binaural processing was measured in a series of tests in patients before and after surgery to correct congenital unilateral conductive hearing losses. Data are presented from 19 patients between the ages of 6 and 33 years that had an abnormal external and/or middle ear on one side but normal hearing in the other ear. Surgery improved thresholds an average(More)
It is generally recognized that surgery for congenital aural atresia is difficult. In an effort to select those patients who have the greatest chance of success, we have developed a grading scheme based on the preoperative temporal bone CT scan and the appearance of the external ear. Patients are graded on a possible best score of 10. The stapes is assigned(More)
PURPOSE The preoperative evaluation of aural atresia and stenosis is strongly dependent upon high resolution CT. We have devised a 10 point surgical rating scale based on high resolution CT of the temporal bone that will provide radiologists with a stepwise method of evaluating these scans and will allow them to communicate these findings to otologic(More)
Benign adenoma of the middle ear emerged as a distinct entity following a review of 20 cases as reported from the Armed Forces Institute of Pathology in 1976. We report 4 additional cases and note that the pathologic diagnosis is not so clear cut. Benign primary adenoma may be confused with adenocarcinoma, ceruminoma, and glomus tumor. The otologic surgeon(More)
OBJECTIVE This study aimed to determine those patients who have sustained a facial nerve injury during surgery for congenital aural atresia and pinpoint the site of injury vis-a-vis the operative approach. STUDY DESIGN The study design was a retrospective review of >1,000 patients undergoing atresia repair. SETTING The study was performed at a tertiary(More)
Congenital atresia of the ear requires prompt diagnosis and an early assessment of hearing. In bilateral atresia, aural rehabilitation should be started early in life to avoid late sequelae of speech problems. In unilateral atresia, the need is not urgent if the child hears normally in the other ear. Polytomography and audiometric testing are the two most(More)
Mucormycosis of the nasal cavity and paranasal sinuses is an aggressive, life-threatening condition characterized by fulminant destruction of soft tissues and bone, vascular invasion, and thrombosis. Patients who have this infection generally are immunosuppressed or diabetic. The most effective treatment is immediate surgical debridement of all involved(More)
The 94 operations analyzed were performed on 80 ears in 73 patients with congenital malformation of the ear. Operative findings included 13 patients with a congenital absence of the oval window, 5 patients with vascular anomaly of the middle ear, and 6 patients with congenital cholesteatoma. Six of 13 patients with congenital absence of the oval window had(More)
Thirty patients with congenital aural atresia underwent CT scanning and/or auditory brain stem response (ABR) testing in a 20-month period. Eighteen patients had unilateral atresia and 12 had bilateral atresia. Twelve patients subsequently had surgery for repair of their atresia. CT scanning was not electively done until the patient was at least 2 years of(More)
