To evaluate the usefulness of cartilage plates as tympanic membranes combined with total middle ear reconstructive surgery for radicalized ears.
Retrospective study between 1994 and 1999.
Tertiary care referral medical center.
Seven patients had seven ears with severe chronic otorrhea after radical mastoidectomy. All patients had severe to profound sensorineural hearing loss and expected a trouble-free ear rather than improved hearing after surgery. Patients were followed up for 4 years postoperatively.
After the middle ear space was cleaned, the tympanic membrane was reconstructed using a plate prepared from the tragal cartilage. The major part of the posterior wall was reconstructed using a conchal cartilage plate. Cortical bone segments were inserted to support the cartilage plate.
Preoperatively, cultures of ear discharge were positive for various bacteria. Recovery with dry eardrums was noted in six patients, and one patient showed minimal erosion. No postoperative complications were encountered, but the hearing threshold did not improve postoperatively.
Total middle ear reconstructive surgery is suitable for patients with chronic otorrhea complicating radical mastoidectomy. The use of cartilage plates seems to be clinically appropriate, particularly for patients with severe infection who expect a trouble-free ear rather than hearing gain after surgery.
评估软骨板作为鼓膜联合全中耳重建手术用于根治性中耳手术耳的有效性。
1994年至1999年的回顾性研究。
三级医疗转诊中心。
7例患者的7只耳在根治性乳突切除术后患有严重慢性耳漏。所有患者均有重度至极重度感音神经性听力损失,且期望术后耳朵无问题而非听力改善。对患者进行术后4年的随访。
清理中耳腔后,使用取自耳屏软骨制备的板重建鼓膜。使用耳甲软骨板重建后壁的主要部分。插入皮质骨段以支撑软骨板。
术前,耳分泌物培养对多种细菌呈阳性。6例患者鼓膜干燥愈合,1例患者有轻微糜烂。未出现术后并发症,但术后听力阈值未改善。
全中耳重建手术适用于根治性乳突切除术后并发慢性耳漏的患者。使用软骨板在临床上似乎是合适的,特别是对于那些严重感染且期望术后耳朵无问题而非听力提高的患者。
