Traumatic Tympanic Membrane Perforations
Hempel et al (2012) reported on 198 patients who experienced traumatic tympanic membrane perforation (TM perf). The mean age of their patients was 29 years of age. Males (62 percent) out-numbered females (38 percent). Of note, when the trauma was "physical blow" to the ear, males and females were essentially equally represented. However, when "collision" was the cause of the TM perf, men (24 percent) outnumbered women (15 percent). With regard to cotton swab-induced TM perfs, women had twice the number of TM perfs than men and the left ear (59 percent) was damaged more often than the right (42 percent, most people are right-handed). With regard to blows, collisions, barotrauma, and the insertion of sharp objects into the ear canal, the inferior section of the TM was the area most often damaged. The authors report that tinnitus, vertigo and hearing loss (secondary to traumatic TM perforation) often have a good prognosis, despite various and multiple therapeutic protocols and a lack of consensus as to how to "best" treat traumatic TM perforation.
