Facial nerve paralysis secondary to chronic otitis media without cholesteatoma

Abstract

Numerous papers have been written on facial nerve paralysis caused by chronic suppurative otitis media. However the authors found none documenting the results of therapy in a series of patients in whom facial nerve dysfunction was caused by chronic otitis media without cholesteatoma. Thus, there is little factual information available to help select a specific therapeutic plan for such cases. Over the past decade, the senior author has managed five cases (6 ears) of chronic suppurative otitis media without cholesteatoma in which facial paresis (4 ears) or paralysis (2 ears) developed 10 days or less before surgery. The chronic otitis media involved the mastoid and middle ear in five cases; and the mastoid, middle ear, and petrous apex in one case. Modified radical mastoidectomy was performed in four ears, tympanomastoidectomy with facial recess exposure in one ear, and complete mastoidectomy with middle cranial fossa petrous apicectomy in one ear. Five patients had complete recovery of facial nerve function (House grade I), and one patient had 90 percent recovery (House grade II). The results provide support for semi-emergent surgery in the management of chronic suppurative otitis media when facial nerve paralysis supervenes.
