Abstract：
Introduction Myringoplasty is a common otologic procedure to restore the integrity of the tympanic membrane in cases of traumatic or pathologic perforations. Many grafting materials have been used with different techniques. Objective In the present work, we evaluate the surgical and audiological outcomes of periosteal graft overlying the mastoid cortex through a retroauricular incision in a pediatric cohort. Methods A retrospective study was carried out involving all children aged ≤ 16 years who underwent periosteal graft myringoplasty for the treatment of chronic suppurative otitis media with dry central perforation in our hospital from April 2019 to April 2021. All patients were followed up for one year to assess the anatomical success and functional outcomes by comparing the preoperative and postoperative (after six months) results of pure tone audiometry (PTA). Results The sample was composed of 36 patients; 20 of them were female (55.6%) and 16 were male (44.4%) subjects, with ages ranging from 7 to 16 (mean: 12.7) years. Four patients underwent surgery in both ears (with an interval of 6 to 9 months). Out of 40 surgeries performed, 38 ears have shown anatomical success (95%). A highly significant improvement in hearing was obtained (the mean difference between the pre- and postoperative results of the PTA was of 14.6 ± 3.45 dB ( p < 0.001). Conclusion We advocate the use of periosteal graft in the pediatric population as a good alternative for other types of grafts, with comparable and even better functional and anatomical outcomes.
摘要：
简介鼓膜成形术是一种常见的耳科手术，可在创伤性或病理性穿孔的情况下恢复鼓膜的完整性。许多接枝材料已经与不同的技术一起使用。目的在目前的工作中,我们评估了儿童队列中通过耳后切口覆盖乳突皮质的骨膜移植物的手术和听力学结果。方法回顾性分析2019年4月至2021年4月在我院接受骨膜移植膜膜修补术治疗慢性化脓性中耳炎干性中央穿孔的所有≤16岁儿童。所有患者均随访一年，通过比较术前和术后（六个月后）纯音测听（PTA）的结果来评估解剖学成功和功能结局。结果36例患者,其中女性20例(55.6%),男性16例(44.4%)。年龄从7到16（平均：12.7）岁。4例患者双耳接受手术（间隔6至9个月）。在40例手术中，38只耳朵显示出解剖学上的成功（95％）。听力得到了显着改善（PTA前后结果的平均差异为14.6±3.45dB（p<0.001）。结论我们主张在儿童人群中使用骨膜移植物作为其他类型移植物的良好替代方法，具有可比甚至更好的功能和解剖学结果。
