Abstract

Purpose: This study aimed to evaluate subtympanic sinus (STS) and its vicinity in high-resolution computed tomography (HRCT) scans of children under five years old with non-diseased temporal bones.

Material and method: We divided the whole group into children under 24 months of age (first stage of pneumatisation development) and between 25 and 60 (second stage). We have determined the width of the entrance to STS, depth of the STS, type in relation to facial nerve according to Anschuetz classification, the pneumatisation of posterior and medial air cell tracts, and jugular bulb position. All the HRCTs (280 temporal bones) were analyzed according to the multiplanar reconstruction protocol with symmetrization.

Results: STS's mean width and depth were 2.71 ± 0.60 mm and 3.26 ± 1.11 mm, respectively. The most common STS type was type A (59.3%), followed by type B (30.7%) and type C (10%). The posterior air cell tract (retrofacial cells) was present in 39.3%. The medial air cell tract (hypotympanic cells) was present in 30.7% The jugular bulb position affected the final shape of STS in 17.5%.

Conclusion: The results support the necessity of the classification for the STS. Our study may help with surgical planning regarding endoscopic ear procedures and gives a broader understanding of how pneumatization or jugular bulb might correlate with the final shape of the retrotympanum. The historical remarks track the term's origin for clarity in research and respect for earlier investigators.

五岁以下儿童鼓下颌窦的放射解剖学评估及其临床意义--高分辨率计算机断层扫描研究。

目的：本研究旨在通过高分辨率计算机断层扫描（HRCT）评估颞骨无病变的五岁以下儿童的鼓室下窦（STS）及其附近的情况：我们将全组儿童分为 24 个月以下（气化发育的第一阶段）和 25 至 60 个月（第二阶段）。我们确定了STS入口的宽度、STS的深度、根据Anschuetz分类法与面神经相关的类型、后部和内侧气胞道的气化情况以及颈静脉球的位置。所有的 HRCT（280 块颞骨）均按照对称的多平面重建方案进行分析：STS的平均宽度和深度分别为2.71 ± 0.60 mm和3.26 ± 1.11 mm。最常见的 STS 类型是 A 型（59.3%），其次是 B 型（30.7%）和 C 型（10%）。39.3%的患者存在后气室束（面后细胞）。颈静脉球位置对 STS 最终形状有影响的占 17.5%：结论：研究结果支持对 STS 进行分类的必要性。我们的研究可能有助于耳内窥镜手术的手术规划，并让人们更广泛地了解气化或颈静脉球与鼓室后的最终形状之间的关系。历史备注追踪了该术语的起源，以便在研究中更加清晰，同时也是对早期研究者的尊重。

期刊介绍： Anatomy is a morphological science which cannot fail to interest the clinician. The practical application of anatomical research to clinical problems necessitates special adaptation and selectivity in choosing from numerous international works. Although there is a tendency to believe that meaningful advances in anatomy are unlikely, constant revision is necessary. Surgical and Radiologic Anatomy, the first international journal of Clinical anatomy has been created in this spirit. Its goal is to serve clinicians, regardless of speciality-physicians, surgeons, radiologists or other specialists-as an indispensable aid with which they can improve their knowledge of anatomy. Each issue includes: Original papers, review articles, articles on the anatomical bases of medical, surgical and radiological techniques, articles of normal radiologic anatomy, brief reviews of anatomical publications of clinical interest. Particular attention is given to high quality illustrations, which are indispensable for a better understanding of anatomical problems. Surgical and Radiologic Anatomy is a journal written by anatomists for clinicians with a special interest in anatomy.
