Description
Summary:Clin. Otolaryngol. 2011, 36, 450–460 Objectives:  To evaluate the outcome of spontaneous healing of aetiology‐, size‐ and type‐different groups of acute traumatic eardrum perforation and to characterise changes in the morphology of the healing eardrum in various conditions. Study design:  Prospective clinical study. Setting:  University‐affiliated teaching hospital. Participants:  A total of 126 patients who visited the Outpatient Department of the Otolaryngology Clinic of Yiwu Central Hospital, Yiwu, China between January 2008 and June 2009 with acute traumatic tympanic membrane perforations. Main outcome measures:  All participants were allowed to heal spontaneously for 12 months. The clinical outcome including healing rate, healing time, hearing function and air–bone gap recovery as well as morphological changes of the healing tympanic membrane was evaluated on the bases of perforation aetiology, size and type, etc. Results:  By perforation size, the overall healing rate at the end of the 12‐month follow‐up was comparable to each other in the three (small, medium and large) size groups (P > 0.05); however, there were significant perforation size‐dependent differences in the average closure time (P  0.05), but the average healing time was different (16 versus 28 days, P  0.05) or closure time (24 versus 27 days). Hearing loss differed significantly between perforations of different causes (P
