Background: The tympanic membrane is an important component of sound conduction system, as an ear trauma may lead to its rupture, so non healed perforation will results in impairment of its function. Aims: To evaluate the factors those have influence on the spontaneous healing of the traumatic tympanic membrane perforations, and their relation, with various types of ear trauma. Patients and methods: A descriptive study of 62 patients attended the Otolaryngology Department / Al-Yarmouk Teaching Hospital in Baghdad, from September 1st 2012 to September 1st 2013, with recent ear trauma, resulted in rupture of their tympanic membrane. The diagnosis was made by history of the ear trauma and otoscopy. The frequency of spontaneous healing was assessed by regular follow up, by the author. Results: The most common type of the ear trauma was blast injury in 43.5%; and the most affected age group was 20-29 years 40.3%. In all types of ear trauma, male were mainly affected, except in slap injury. The smallest size perforation was 51.5%, and it is found in 93.8% of slap trauma. The most common site was posterior perforation 50%, and it is found in all types of ear trauma. The incidence of the spontaneous healing was 81.81%, and the highest frequency of healing was found in slap injury 100% as well as in small size tympanic membrane perforation was 94.1%. Conclusions: The frequency of the spontaneous healing of traumatic tympanic membrane perforation is high, and the factors that affect its healing include the types of the ear trauma, the size of perforation, and the ear infection. The maximum incidence of spontaneous healing is found in slap trauma, in small sized perforation, and in the absence of ear infection.
