Otapostasis

Otapostasis or protruding ear (protrusion) is a congenital condition or a result of specific surgeries like mastoidectomy, which causes dissatisfaction in the patients. There are a few surgical interventions available to correct the deformity and none of them are hundred percent effective. The present study introduces a novel method to correct protruding ear in the patients after mastoidectomy. The study was carried out as a clinical trial. A corrective surgery of the auriculo posterior muscle was performed on the patients in the intervention group. This muscle is usually damaged during mastoidectomy and left untreated since it is not a critical muscle. Taking into account the paucity of research works on protruding ear and the importance of finding an effective corrective method, the subject of this study is one of the research priorities in the field of reconstructive surgery. Based on the findings, recommendations in the field of novel corrective surgery for protruding ear were formulated. Mastoidectomy is performed to remove mastoiditis air cells from mastoid [1]. There are different reasons like mastoiditis, ear infection, and or cholesteatoma that make mastoidectomy necessary [2]. Air cells are empty spaces inside mastoid in which air can flow. Infections of middle ear might be expanded through mastoid and when antibiotics are ineffective, mastoidectomy becomes necessary [3, 4]. Intact canal wall mastoidectomy: There are different methods for performing mastoidectomy and the best option depends on the condition of patient [5]. In one method, a cut is made behind the ear to open Mastoid and find access to infectious cells. To discharge the extra liquid, a small radical mastoidectomy and modified radical mastoidectomy are notable [7]. In the latter technique, a considerable portion of the bone is removed to treat cholesteatoma so that tympanic membrane and the elements of middle ear are removed. However, stapes remains intact to preserver the patient’s hearing capability [8, 9]. In the case of modified mastoidectomy, the tympanic membrane is reconstructed through tympanoplasty after removing the bones of middle ear [10]. In fact, the normal auriculo cephalic angle (ACA) in the optimum condition should be 30°; this angle in normal people ranges from 25° to 35°, and it is an ear anomaly when the angle ranges from 40° to 45° [11].
