Lipoma of the Deep Neck Space / 대한이비인후과학회지

Lipoma is a common tumor throughout the body, but occurrence in the deep neck space is very rare, and only some cases have been reported by otolaryngologist and pathologist for the last century. In head and neck area, as elsewhere, the lipoma is mainly originated from the subcutaneum. But in deeper tissues, its characteristics are different from those of other sites of lipoma. Submucosal lipoma in the head and neck area usually occur in oral cavity and hypopharynx. Recently we hae experienced 3 cases of deep neck space lipoma, so we report our clinical experiences with brief review of literature.

Surgical Experiences of Congenital Aural Atresia Analysis of 53 Cases / 대한이비인후과학회지

Congenital aural atresia requires reconstructive surgery because of its negative effect against hearing and cosmetic problem. Two surgical methods, anterior and transmastoid approaches, have been designed for the surgery and many surgeons have advocated any techniques depending on their surgical experiences and advantages of each method. We analyzed retrospectively 53 cases of congenital aural atresia operated with the use of one of both approaches, and got the clinical, audiological and surgical results as follows. 1) Postoperative dressing period was shorter in the anterior approach(34.5 days) than in the posterior one(44.2 days). 2) Hearing results are better in the anterior approach. 3) Postoperative complications include granulation tissue formation, drum lateralization, external auditory canal stenosis and temporary facial nerve weakness. And it happened more frequently in the anterior approach than the posterior one. 4) Facial nerve anormaly was noted in 16 cases(30.2%) and cholesteatoma in 5 cases(9.4%).
