OBJECTIVE To present the clinical results of closing chronic tympanic membrane (TM) perforations using basic fibroblast growth factor (bFGF) combined with an atelocollagen/silicone bilayer membrane patch. STUDY DESIGN Closure of TM perforations in 87 patients was attempted using bFGF, which is thought to promote the regeneration of TM tissues by(More)
In 29 ears of 24 patients with auditory ossicle malformation, but without external ear abnormalities, who were operated on at our clinic in the 10 years between June 1993 and June 2002, we studied the condition of ossicles, preoperative examination, surgical procedures, and postoperative hearing improvement. Our study did not include patients with(More)
Our surgical treatment for middle ear cholesteatoma is based on the following 2 concepts: (1) Preservation of the physiological morphology and function of the middle ear, that is, maximal preservation of the posterior wall of the external auditory meatus and the middle ear mucosa and (2) Careful resection of the matrix membrane of the cholesteatoma through(More)
This retrospective study examined the etiology and treatment results for traumatic, conductive hearing loss in 22 patients who underwent surgery between 1998 and 2008 at Osaka Red Cross Hospital. All patients underwent computed tomography (CT) of the temporal bone preoperatively. The ear surgery comprised closure of the ruptured tympanic membranes and(More)
We studied 35 ears of 34 patients with congenital cholesteatoma who were operated between June 1992 and May 2003, focusing on the localization and progression of congenital cholesteatoma. Patients were 2 to 55 years of age. Congenital cholesteatoma was diagnosed based on two intraoperative findings: 1) no continuity between the tympanic membrane and(More)
