In the first item it is stated that traumatic tympanic membrane perforations recover spontaneously at a very high rate, and the factors affecting healing are mentioned. It is stated that insufficient emphasis has been given to the factors affecting spontaneous healing and corrections should be made to the inclusion criteria. Traumatic perforations often develop because of a slap injury, blast injury, accident, sporting injury, or instrumental injury, and 53–94% recover spontaneously [1–4]. Research has revealed that the mean time of spontaneous healing of traumatic TM perforation is 25.9 days, but may be as long as 3 months [5]. Although the rates of closure of TM perforation do not vary greatly, immediate microsurgery procedures for the purpose of accelerating the healing process are preferred in patients with traumatic perforation [6,7]. In the current study, the mean time to closure of the TM perforation was 7.8 days in Group 1, where PRF was applied [8]. This is a double-blind study comparing PRF membrane and the paper-patch method in patients with traumatic perforation. Spontaneous healing is not the subject of this study. The aim of the study is to compare the success rates of the methods applied to similar groups. Factors affecting spontaneous healing include age, sex, size and position of perforation, left or right ear, cause of injury, curly edges, and pre-existing myringosclerosis [1,9–11]. The age and gender of the patients, dimensions of the perforation, and cause of injury have been stated in the article. It is clear that pre-existing myringosclerosis would have a negative effect on healing. As stated in the paper, patients with otological problems such as myringosclerosis were not included in the study (no other otological problems). There are studies showing that curly edges have an effect on healing and studies which have shown no effect [2,6,11,12]. Our views are that there is no effect. We have not understood the request for the effect on healing according to whether the perforation was in the right or left ear to be included in the criteria.
