Traumatic perforation of the tympanic membrane may be due to direct or indirect source. The aim of the study is to profile the various aetiologies of traumatic tympanic membrane perforation in Ilorin, north central Nigeria.A retrospective review of 64 patients seen at the University of Ilorin Teaching hospital, Ilorin, Nigeria over a ten year period (January 1998 to Dec 2007) with history of traumatic tympanic membrane perforation from various causes, these also included multiply injured patients with bleeding from middle ear as part of their presentations. The data retrieved included the biodata, the clinical presentations, source of injury, the clinical findings and the treatment outcome. The data were entered into an SPSS version 11 computer soft ware and analyzed descriptively.
Sixty four (64) ears were analysed, Age range 6 months to 50 yrs, mean age of 29.2 yrs 7.9% of them were <or=5 years, 29.7% between 21-34 years, and 37.7% were 35 years and above. The male to female ratio was 2.5:1.0. Commonest aetiology was from slaps, then road traffic injury (RTI) in 35.9% and 23.5%, Majority of the slap injury were from fights (30.5%), security agents, senior students and cultists at schools (17.4% each). Sudden hearing loss was a typical presentation (95.3%), majority of the patient defaulted from follow up once the symptoms of bleeding and pain subsided. Only 7.8% had neomembrane formation on follow up
Traumatic perforation of the tympanic membrane is an uncommon injury that is under-reported, there is the need to educate on alternative punitive measure among students and security agents, unskilled removal of foreign body, early identification, evaluation and referral of patients reduces the attendant morbidity.
鼓膜外伤性穿孔可能源于直接或间接原因。本研究旨在剖析尼日利亚中北部伊洛林地区外伤性鼓膜穿孔的各种病因。对在尼日利亚伊洛林大学教学医院就诊的64例患者进行回顾性研究，这些患者在10年期间（1998年1月至2007年12月）有各种原因导致的外伤性鼓膜穿孔病史，其中还包括多处受伤且伴有中耳出血作为其临床表现一部分的患者。检索的数据包括生物统计学资料、临床表现、损伤来源、临床检查结果及治疗结果。数据录入SPSS 11版计算机软件并进行描述性分析。
分析了64只耳，年龄范围为6个月至50岁，平均年龄29.2岁。其中7.9%年龄≤5岁，29.7%在21 - 34岁之间，37.7%为35岁及以上。男女比例为2.5:1.0。最常见的病因是掌掴，其次是道路交通伤（RTI），分别占35.9%和23.5%。大多数掌掴伤来自打架（30.5%）、保安人员、学校高年级学生和邪教成员（各占17.4%）。突发听力损失是典型表现（95.3%），大多数患者在出血和疼痛症状消退后就不再复诊。随访时仅有7.8%有新鼓膜形成。
鼓膜外伤性穿孔是一种报告不足的罕见损伤，有必要对学生和保安人员开展关于替代惩罚措施的教育，非专业地取出异物、早期识别、评估和转诊患者可降低随之而来的发病率。
