Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 10
Abstract
OBJECTIVE: The purposes of this study were to determine the factors involved in the spontaneous healing and to profile the various etiologies of traumatic tympanic membrane (TM) perforation. METHOD –A Prospective study was performed on 70 cases of traumatic perforation in Dept of ENT , JL.N.M.CH BHAGALPUR from January 2010 to march 2013. RESULTS:A total 70 patients with traumatic TM perforations were enrolled in the study. The group consisted of 46 male and 18 female patients. It affected all with the highest incidence among middle age group .. The types of trauma included compression injury, blast injury , and instrumental injury . The causes of conflict by a slap or a fist were spouse or lover (52%), parents and sibling (3%), school teachers (4%), schoolmate (12%), state police and prisoner (7%), and blow against the ear during street fight (22%).. Wet perforations with bloody or watery discharge significantly improved the healing rate ) and shortened the average perforation closure time as compared with dry perforations. Although the perforation that involved malleus or umbo damage did not significantly affect the healing rate, a significantly prolonged closure time (41.6 vs 23.8 days) was observed as compared with no damage. However, the curled edges did not also affect the outcome of spontaneous healing; the healing rate was 91% and 88%, and the average closure time was 28.1 and 26.7 days, respectively, for with and without curler edges. By perforation size, the overall healing rate was 92% and 54%, and the average closure time was 22.8 and 47.3 days , respectively, for small and larger perforations. Moreover, 7 patients had neomembrane formation on follow-up, 2 developed cholesteatoma, 1 developed tympanosclerosis, and 1 developed facial paralysis. CONCLUSION: In our experience domestic violence and street flight were the most common cause of a traumatic TM perforation. Traumatic perforation have excellent prognosis. However ,preexisting typanosclerosis and the perforation that involved malleus or umbo damage could lengthen the healing time of perforation. Wet perforation with bloody or watery discharge accelerate the healing but the curled edge did not affect the outcome of spontaneous healing.
