OBJECTIVE
To prevent cavity problems in canal wall down mastoidectomy, silicone block for mastoid obliteration was used.
METHODS
In this retrospective cohort study, 39 patients (21 males and 18 females) underwent canal wall down mastoidectomy and mastoid obliteration using silicone block. We evaluated the postoperative outcome, the time until epithelialization of the cavity, graft success rate, and the hearing outcome.
RESULTS
The time until complete epithelialization of the mastoid cavity was 35.5 ± 5.4 days. We had a graft success rate of 100% during the follow-ups. The postoperative evaluation revealed 36 dry ears (92.3%) patients without any cavity problems. However, one ear developed granulation tissue, and two ears had partially exposed silicone block, which required revision mastoidectomy. Regarding hearing outcomes, a complication such as deaf ear was not reported.
CONCLUSION
Silicone block is safe and suitable for mastoid obliteration and external auditory canal reconstruction in canal wall down mastoidectomy.
LEVEL OF EVIDENCE
目的
为预防开放式乳突根治术中的术腔问题，采用硅胶块进行乳突腔填塞。
方法
在这项回顾性队列研究中，39例患者（21例男性和18例女性）接受了开放式乳突根治术及使用硅胶块的乳突腔填塞术。我们评估了术后结果、术腔上皮化所需时间、植片成功率及听力结果。
结果
乳突腔完全上皮化的时间为35.5±5.4天。随访期间植片成功率为100%。术后评估显示36例（92.3%）患者术腔干燥，无任何术腔问题。然而，1例耳出现肉芽组织，2例耳硅胶块部分外露，需行翻修乳突根治术。关于听力结果，未报告诸如全聋等并发症。
结论
硅胶块用于开放式乳突根治术中的乳突腔填塞及外耳道重建是安全且合适的。
