To examine the effects of mastoid and middle-ear volume on the anatomical and functional success of type 1 tympanoplasty in paediatric patients.
This study included 45 paediatric patients who underwent type 1 cartilage tympanoplasty. Patients' demographic data, pre- and post-operative audiological evaluation results, and post-operative graft status were evaluated. Middle-ear and mastoid cavity volumes were calculated (in cubic centimetres) using temporal bone high-resolution computed tomography. Middle-ear and mastoid cavity volume values were compared between patients with and without post-operative anatomical and functional success.
Anatomical success was achieved in 82.2 per cent of patients (n = 37), and functional success in 68.9 per cent (n = 31). When anatomical success and failure groups were compared, a statistically significant difference was found in mean mastoid volume (p = 0.037), while there was no significant difference in relation to mean middle-ear volume (p = 0.827). The comparison of functional success and failure groups revealed no significant difference in mean mastoid volume (p = 0.492) or middle-ear volume (p = 0.941).
The study showed that mastoid pneumatisation volume affects surgical success in paediatric tympanoplasty.
研究乳突和中耳体积对儿童患者 1 型鼓室成形术解剖学和功能成功的影响。
本研究纳入了 45 例接受 1 型耳甲腔成形术的儿科患者。评估了患者的人口统计学数据、术前和术后听力评估结果以及术后移植物状况。使用颞骨高分辨率计算机断层扫描（CT）计算中耳和乳突腔体积（以立方厘米计）。比较了术后解剖学和功能成功患者与未成功患者的中耳和乳突腔体积值。
82.2%（n=37）的患者达到了解剖学成功，68.9%（n=31）的患者达到了功能成功。在解剖学成功和失败组之间进行比较时，乳突体积的平均值存在统计学显著差异（p=0.037），而中耳体积平均值则无显著差异（p=0.827）。在功能成功和失败组之间的比较中，乳突体积（p=0.492）或中耳体积（p=0.941）的平均值均无显著差异。
该研究表明，乳突气化体积影响儿童鼓室成形术的手术成功率。
