氣化鈎狀突與慢性副鼻竇炎-三例報告

Uncinate Bulla and Chronic Paranasal Sinusitis - Report of Three Cases

摘要


已知鼻竇口道綜合體(ostiomeatal complex)在解剖上或黏膜性的阻塞是引起慢性副鼻竇炎的主因,而其解剖上的異常包括有氣化中鼻甲、異位中鼻甲、Haller’s cell及氣化鈎狀突(uncinate bulla)等,其中又以氣化鈎狀突最為少見。本科自1995年8月至1996年7月共經歷3名男性、5側的氣化鈎狀突,他們的主要症狀包括有鼻塞、鼻涕倒流、黃膿鼻涕及頭痛達數年之久。3名患者在接受功能性鼻竇內視鏡手術後症狀均能獲得明顯改善。由於氣化鈎狀突無法由鼻竇X光片及鼻竇內視鏡來判讀,而有賴於鼻竇電腦斷層之正確術前評估,且氣化鈎狀突較為少見,故特別提出病例報告。

並列摘要


Anatomical variants and mucosal contact at the ostiomeatal complex region may possibly be facters resulting in chronic paranasal sinusitis (CPS). Anatomical variations include concha bullosa, paradoxical curvature of the middle turbinate, Haller’s cell and uncinate bulla. Among them, uncinate bulla occurs least frequently. Three men, 31 to 47 years old, with uncinate bulla on five sides of the ostiomeatal complex were diagnosed with CPS from August 1995 to July 1996 in our department. After being treated with minimally invasive surgery using functional endoscopic infundibulo-tomy, there CPS symptoms greatly improved. The uncinate process is at a critical location in the middle meatus. The uncinate bulla, present alone or in combination with other surrounding anomalies, may be one of the main facters in CPS. Detection of an uncinate bulla is difficult with conventional sinus x-ray or nasosinal endoscopy. Therefore, a pre-operative sinus CT scan is highly recommended.
