摘要

上顎鼻竇增高手術可用來增加齒槽塉高度，幫助臨床醫師處理嚴重齒槽骨塉吸收處的人工植牙贋複工作。有研究報告指出，鼻竇增高手術術後發生鼻竇炎症狀的現象會減低人工植牙的成功率，然而術前鼻竇黏膜病變或鼻竇炎的症狀對局部齒槽骨塉增高術所可能產生的影響則較少被提及，本篇病例報告提出兩份病例，分別是術前鼻竇黏膜病變的患者，進行鼻竇增高手術，並針對其可能產生的影響與術後的結果進行討論。觀察結果得知：經過詳盡的術前病史的詢問，配合各項放射線攝影和臨床評估與適當手術流程，儘管本篇所示兩份病例報告皆有術前鼻竇黏膜異常現象，但鼻竇增高手術的結果並不受影響，同時術後密切的回診照護，有助於減低術後併發症，達到人工植牙的成功結果。

Sinus augmentation procedures are commonly used to increase bone height and to facilitate implant placement in the maxillary posterior areas. Mucosal pathologies in maxillary sinuses including mucosal thickening and retention cysts, associated or not associated with sinusitis, are occasionally found on the dental radiographs or computed tomographic (CT) films. These are traditionally considered as contraindications for sinus lifting procedures. This report, however, presents two cases in which sinus lifting surgery were performed in patients with mucosal pathologies of maxillary sinuses. The first case presented a 47-year-old female patient with an asymtomatic retention cyst in her left maxillary sinus. The second case was a 55-year-old male patient presented with bilateral thickened Schneiderian membrane and mild symptoms of sinusitis. In both cases, sinus lift and grafting procedures with lateral approach were successfully performed, without subsequent complications in the sinuses and grafted sites.
