High incidence of complications encountered in chronic otitis media surgery in a U.S. metropolitan public hospital.

OBJECTIVES

To examine the incidence and nature of complicating factors in surgery for chronic otitis media (COM) in a metropolitan public hospital in the United States.

METHODS

A retrospective review was performed over 2 years in a metropolitan public hospital to identify cases of surgery for chronic ear disease with the following complicating factors: intracranial or extracranial abscess, labyrinthine fistula, dural dehiscence with or without associated encephalocele or meningocele, or extensive involvement of the facial nerve by cholesteatoma with or without paralysis.

RESULTS

Thirty-three of 90 consecutive operations for COM (37%) met criteria for complicated chronic otitis media (CCOM). The majority (85%) of patients had cholesteatoma involvement. Most patients (73%) were managed by an extended modified radical mastoidectomy. An additional 31 procedures were required in these 33 patients for control of complications. There was no iatrogenic sensorineural hearing loss or facial paralysis.

CONCLUSIONS

The incidence of CCOM in this large, U.S. metropolitan public hospital is similar to that observed in developing nations. CCOM significantly complicates chronic ear surgery and substantially increases the use of resources. Maintaining functional hearing is possible, but difficult, and should be considered secondary to prevention of further complications and eradication of disease. Access to health care and proper follow-up are crucial in prevention of CCOM.
