Mastoid cortex defects resulting from mastoidectomy surgery can rarely lead to negative sequelae, including unsightly post-auricular depression and discomfort. This study sought to evaluate the use of hydroxyapatite cement (HAC) to reconstruct mastoidectomy cortex defects.
Retrospective chart review was undertaken for all patients that underwent reconstruction of the mastoid cortex using HAC at a single tertiary medical center between 2013 and 2019. Collected data included demographics, indications for mastoidectomy, complications, and associated symptom status.
Twenty-nine patients that underwent mastoid cortex repair using HAC were included, and ten of these underwent mastoid revision in a secondary procedure to reconstruct the mastoid cortex with a specific goal to eliminate negative signs and symptoms. There were no associated postoperative complications and no instances of post-auricular depression following repair. All cases of secondary reconstruction resolved the primary signs and symptoms that prompted mastoid revision.
HAC mastoid cortex reconstruction may be a safe and effective method to resolve negative sequelae resulting from previous mastoidectomy defects. Also, upfront HAC mastoid cortex reconstruction appears viable in select instances as an option to prevent potential future complications.
乳突切除术引起的乳突皮质缺损罕见地会导致不良后遗症，包括耳后难看的凹陷和不适。本研究旨在评估使用羟基磷灰石水泥（HAC）重建乳突皮质缺损。
对 2013 年至 2019 年期间在一家三级医疗中心接受 HAC 重建乳突皮质的所有患者进行回顾性图表审查。收集的数据包括人口统计学、乳突切除术的指征、并发症和相关症状状况。
共纳入 29 例患者，其中 10 例在二次手术中进行乳突修正，以特定的目标重建乳突皮质，消除负面迹象和症状。术后无相关并发症，修复后无耳后凹陷。所有二次重建的病例均解决了促使乳突修正的主要症状和体征。
HAC 乳突皮质重建可能是一种安全有效的方法，可以解决以前乳突切除术缺陷引起的不良后遗症。此外，在某些特定情况下，HAC 乳突皮质的初始重建似乎是一种可行的选择，可以预防潜在的未来并发症。
