There is a consensus about the occurrence of otitis media in children with cleft palate before repair. However, controversy continues regarding the recovery of Eustachian tube function and level of hearing loss in the patients after cleft palate repair. Levator sling palatoplasty is an important component of the cleft repair. Most surgeons would routinely transect the tensor tendon (tensor tenotomy) during the course of palatoplasty. However, this procedure may pose a risk to Eustachian tube function. Some authorities feel that addition of tensor tenopexy during palatoplasty would maintain the Eustachian tube in an open conformation, thereby improving middle ear ventilation. The present study assesses the effectiveness of tensor tenopexy in improving Eustachian tube function and preventing hearing loss in cleft palate patients treated with palatoplasty. A prospective randomised controlled trial was conducted in the Department of Plastic Surgery at a tertiary care institute in India. A total of 17 children in the age group of 9-24 months were assigned to one of two groups: palatoplasty with either tensor tenotomy (n = 8) or tensor tenotomy with tensor tenopexy (n = 9). All patients were subjected to tympanometry, otoscopy and brainstem evoked response audiometry before surgery and at 3, 6, 9 and 12 months after surgery. Of these, 52.9% of patients already had hearing loss at the time of presentation. Hearing loss and middle ear effusion persisted even after palatoplasty. There was no significant difference in hearing loss and middle ear effusion between the two groups of patients. Thus, tensor tenopexy was not found to be helpful in maintaining Eustachian tube function or preventing hearing loss in cleft palate patients. However, further long-term studies are needed to confirm this study.
人们普遍认为腭裂患儿在修复前会发生中耳炎。然而,对于腭裂修复后患者咽鼓管功能的恢复和听力损失程度,仍存在争议。提腭肌吊带术是腭裂修复的重要组成部分。大多数外科医生在腭裂修复过程中会常规横断张量肌腱(张量肌腱切断术)。然而,这一手术过程可能会对咽鼓管功能造成风险。一些权威人士认为,在腭裂修复术中增加张量肌腱固定术,可以使咽鼓管保持开放状态,从而改善中耳通气。本研究评估了在腭裂患者行腭裂修复术中行张量肌腱固定术对改善咽鼓管功能和预防听力损失的效果。这是在印度一家三级护理机构的整形科进行的一项前瞻性随机对照试验。共有 17 名 9-24 月龄的儿童被分为两组之一:行腭裂修复术且行张量肌腱切断术(n=8)或行腭裂修复术且行张量肌腱切断术+张量肌腱固定术(n=9)。所有患者在手术前和手术后 3、6、9 和 12 个月均接受鼓室压测定、耳镜检查和脑干诱发电位测听。其中,52.9%的患者在就诊时已经存在听力损失。即使在腭裂修复术后,听力损失和中耳积液仍然存在。两组患者的听力损失和中耳积液无显著差异。因此,张量肌腱固定术对于维持腭裂患者的咽鼓管功能或预防听力损失并无帮助。然而,还需要进一步的长期研究来证实这一研究结果。
