Various techniques have been described in the reconstruction of mastoidectomy cavity in an attempt to minimize or control the problems of persistent postoperative otorrhoea. We report the efficacy of deep temporalis fascia and its pedicled flap in 34 cases. Retrospective study method was used. There were 34 cases, 19 males and 13 females, the age ranged between 5 and 64 years, mean of 28 years. The clinical pathology included mastoiditis which was common to all the patients, others are middle ear polyp in 7, mastoid abscess 6, meningitis 4, lateral sinus thrombosis 3 and cholesteatoma 2. Comorbidity factors included diabetes mellitus in 2, moderate anaemia in 3 and septicaemia in 7. The procedures comprised of 18 modified radical mastoidectomy (MRM) and 8 atticoantrostomy (AA) with lining of the resulting cavity and tympanoplasty using a pedicled temporalis fascia flap; and 8 cortical mastoidectomy (CM) and tympanoplasty using a graft. The success rate in terms of control of otorrhoea was 55% and there was no case of postoperative wound infection, an improvement compared to an earlier report. In addition there was a reduction in terms of postoperative hospital stay to an average of 9 days. We found the technique simple to learn and needing minimal equipment, hence relevant to otolaryngologic practice in a resource--poor environment. In addition the deep temporalis fascia is an autologous tissue with no risk of immune rejection. We recommend that mastoid reconstruction with the temporalis fascia becomes a routine in mastoidectomy so as to achieve control of chronic discharging ear, particularly in the sub-Saharan Africa where this is still predominant.
为尽量减少或控制乳突切除术后持续性耳漏问题,已有多种技术用于乳突切除腔的重建。我们报告了34例颞肌深筋膜及其带蒂皮瓣的疗效。采用回顾性研究方法。共34例患者,男性19例,女性13例,年龄5至64岁,平均28岁。临床病理包括所有患者均有的乳突炎,其他还有中耳息肉7例、乳突脓肿6例、脑膜炎4例、乙状窦血栓形成3例和胆脂瘤2例。合并症因素包括糖尿病2例、中度贫血3例和败血症7例。手术包括18例改良乳突根治术(MRM)和8例上鼓室鼓窦切开术(AA),术后腔隙内衬并使用带蒂颞肌筋膜瓣进行鼓室成形术;以及8例皮质乳突切除术(CM)并使用移植物进行鼓室成形术。耳漏控制成功率为55%,且无术后伤口感染病例,与早期报告相比有所改善。此外,术后住院时间平均缩短至9天。我们发现该技术易于学习且所需设备最少,因此适用于资源匮乏环境下的耳鼻喉科实践。此外,颞肌深筋膜是自体组织,无免疫排斥风险。我们建议,采用颞肌筋膜进行乳突重建应成为乳突切除术中的常规操作,以控制慢性流脓性耳病,特别是在撒哈拉以南非洲地区,这种疾病仍然很普遍。
