摘要

本研究旨在使用高分辨率计算机断层扫描（HRCT）评估单侧小耳症患者的乳突体积和尺寸，以提高重建手术规划的精确度。方法在2020年5月至2022年8月期间，Cipto Mangunkusumo综合医院对单侧小耳症患者的HRCT乳突扫描进行了回顾性分析。在耳道、上半规管（SCC）和侧规管水平测量了乳突体积、高度和表面积等参数。结果分析表明，与对侧耳相比，患侧耳乳突气胞体积和乳突骨体积的中位数有统计学意义的显著下降（分别为 p = 0.0312 和 p = 0.02）。结论单侧小耳畸形患者患侧乳突骨体积参数和尺寸减小。这些发现为外科医生制定术前计划提供了重要数据，使他们能够选择适当的重建技术，并为患者提供全面的咨询服务。

Evaluation of mastoid volume and dimensions in unilateral microtia patients: retrospective study using High Resolution Computed Tomography (HRCT)

Objective

The aim of this study is to evaluate mastoid volume and dimensions in patients with unilateral microtia using High-Resolution Computed Tomography (HRCT) to enhance the precision of reconstructive surgical planning.

Methods

A retrospective analysis of HRCT mastoid scans from patients with unilateral microtia was carried out at Cipto Mangunkusumo General Hospital between May 2020 and August 2022. Parameters such as mastoid volume, height, and surface area were measured at the ear canal, Superior Semicircular Canal (SCC), and lateral SCC levels.

Results

The analysis revealed statistically significant decreases in median mastoid air cell volume and mastoid bone volume in the affected ears compared to contralateral ears (p =  0.0312 and p =  0.02, respectively). Additionally, decreased mastoid height and surface areas at the ear canal and superior SCC levels were identified in affected ears (p <  0.05).

Conclusions

Patients with unilateral microtia have diminished mastoid bone volumetric parameters and dimensions on the affected side. These findings offer critical data for surgeons in preoperative planning, enabling the selection of appropriate reconstructive techniques and providing comprehensive patient counselling.

Level of evidence

Level 4.

期刊介绍： Brazilian Journal of Otorhinolaryngology publishes original contributions in otolaryngology and the associated areas (cranio-maxillo-facial surgery and phoniatrics). The aim of this journal is the national and international divulgation of the scientific production interesting to the otolaryngology, as well as the discussion, in editorials, of subjects of scientific, academic and professional relevance. The Brazilian Journal of Otorhinolaryngology is born from the Revista Brasileira de Otorrinolaringologia, of which it is the English version, created and indexed by MEDLINE in 2005. It is the official scientific publication of the Brazilian Association of Otolaryngology and Cervicofacial Surgery. Its abbreviated title is Braz J Otorhinolaryngol., which should be used in bibliographies, footnotes and bibliographical references and strips.
