This study presents a 15 year experience of surgical treatment in 47 patients with congenital atresia of the ear. Emphasizing on the importance of pre-surgical evaluation of the patients for a better prognostic indicator. The ages of 40 patients were between 5-15 years. 24 patients (61%) had complete atresia and 23 (49%) incomplete. 27 patients (57%) with bilateral disease and 20 (43%) unilateral. Auditory test before surgery showed a conductive hearing loss of approximately 60 decibels (dB) and one case with total sensorineural hearing loss. There was an auditory average gain of 28.3 dB. 3 patients (6.4%) had associated cholesteatoma. Complications presented: Closure of the external auditory canal in 6 patients (12.7%), and facial nerve paralysis in 2 patients with recovery. The different surgical technics are described. In conclusion, for this type of surgery, combination between the otologist and plastic surgeon should be done for better results.
本研究展示了对47例先天性耳道闭锁患者进行手术治疗的15年经验。强调了对患者进行术前评估对于更好的预后指标的重要性。40例患者的年龄在5至15岁之间。24例患者(61%)为完全闭锁,23例(49%)为不完全闭锁。27例患者(57%)为双侧病变,20例(43%)为单侧病变。术前听力测试显示传导性听力损失约60分贝(dB),1例为完全感音神经性听力损失。听觉平均增益为28.3 dB。3例患者(6.4%)伴有胆脂瘤。出现的并发症有:6例患者(12.7%)外耳道闭锁,2例患者出现面神经麻痹但已恢复。文中描述了不同的手术技术。总之,对于此类手术,耳科医生和整形外科医生应联合进行手术以获得更好的效果。
