Abstract

Facial nerve paralysis caused by a vestibular schwannoma is a rare but critical symptom; however, few reports have focused on preoperative facial nerve palsy from the viewpoint of treatment. In addition, its mechanism is not fully understood. We report a rare case of preoperative facial nerve palsy that improved after the surgical resection of a small vestibular schwannoma with hearing preservation. A small vestibular schwannoma within the internal auditory canal caused acute deafness and facial paralysis in a 51-year-old woman. Conservative treatment was initially administered, but severe hearing loss and facial paralysis persisted for 3 months after onset. Subsequently, we performed tumor resection using the retrolabyrinthine approach. The tumor, which compressed the cochlear and facial nerves, was almost completely removed under continuous intraoperative monitoring to preserve the facial nerve function. “Wait and scan” is generally recommended for vestibular schwannomas within the internal auditory canal. However, this case suggests that early successful surgery, at least in selected cases, can improve paralysis without hearing deterioration and maintain the patient's quality of life.

期刊介绍： The international journal Auris Nasus Larynx provides the opportunity for rapid, carefully reviewed publications concerning the fundamental and clinical aspects of otorhinolaryngology and related fields. This includes otology, neurotology, bronchoesophagology, laryngology, rhinology, allergology, head and neck medicine and oncologic surgery, maxillofacial and plastic surgery, audiology, speech science. Original papers, short communications and original case reports can be submitted. Reviews on recent developments are invited regularly and Letters to the Editor commenting on papers or any aspect of Auris Nasus Larynx are welcomed. Founded in 1973 and previously published by the Society for Promotion of International Otorhinolaryngology, the journal is now the official English-language journal of the Oto-Rhino-Laryngological Society of Japan, Inc. The aim of its new international Editorial Board is to make Auris Nasus Larynx an international forum for high quality research and clinical sciences.
