摘要

本研究基于221只耳朵的高分辨率计算机断层扫描,对0.7至91岁的耳道几何形状进行了全面分析。量化特征包括沿根管长度的横截面积、根管总长度、曲率和关键解剖标志,如第一和第二弯以及软骨到骨的过渡。重大的发育变化发生在生命的前10年,在10到15岁之间出现成年人的特征,可能与青春期同时发生。在所有年龄段都观察到大量的个体间差异,特别是在运河区域。到0.7岁时,在第二次弯曲处和外侧的椎管完全成为软骨,此后仅在骨段进一步生长。这些解剖学发现对听力学阈值评估、宽带声阻抗测量、适龄助听器安装计划和手术计划具有重要意义,特别是在解剖差异最大的儿科人群中。

Comprehensive Measurements and Analyses of Ear Canal Geometry From Late Infancy Through Late Adulthood: Age-Related Variations and Implications for Basic Science and Audiological Measurements.

This study provides a comprehensive analysis of ear canal geometry from 0.7 to 91 years, based on high-resolution computed tomography scans of 221 ears. Quantified features include cross-sectional areas along the canal's length, total canal length, curvature, and key anatomical landmarks such as the first and second bends and the cartilage-to-bone transition. Significant developmental changes occur during the first 10 years of life, with adult-like characteristics emerging between ages 10 and 15 years, likely coinciding with puberty. Substantial interindividual variability is observed across all ages, particularly in the canal area. The canal becomes fully cartilaginous at and lateral to the second bend by 0.7 years, with further growth occurring only in the bony segment thereafter. These anatomical findings have important implications for audiologic threshold assessments, wideband acoustic immitance measures, age-appropriate hearing aid fitting schedules, and surgical planning, particularly in pediatric populations where anatomical variation is greatest.

期刊介绍: Trends in Hearing is an open access journal completely dedicated to publishing original research and reviews focusing on human hearing, hearing loss, hearing aids, auditory implants, and aural rehabilitation. Under its former name, Trends in Amplification, the journal established itself as a forum for concise explorations of all areas of translational hearing research by leaders in the field. Trends in Hearing has now expanded its focus to include original research articles, with the goal of becoming the premier venue for research related to human hearing and hearing loss.
