title: Middle-ear pressure changes in relation to recurrent otitis externa.
abstract: Middle-ear pressure was estimated in 28 patients who suffered from recurrent attacks of bacterial otitis externa, but without systemic disease. The middle-ear pressure was found to be normal in seven cases, mildly negative in 15 cases, and severely reduced in six cases. Restoration of the middle-ear pressure greatly improved the condition of the external ear in most cases.
