摘要

使用人工植牙重建上顎後牙區時，若上顎骨脊高度不足常須使用鼻竇增高術增加骨脊的高度，以利後續人工植牙的置入。在進行鼻竇增高術之前，利用電腦斷層觀察鼻竇的解剖形態有助於選擇適當的手術方式及瞭解術中會經歷的解剖構造，減少併發症的發生。本篇提出三個關於鼻竇解剖構造的病例，其中包括上顎竇中隔、上顎竇血管和上顎竇斜坡，以及後續的手術進行及追蹤。

Maxillary sinus floor elevation is a bone augmentation technique that is used to increase the vertical dimension of a posterior atrophic maxilla to allow the placement of dental implants. Using CT imaging to study the sinus anatomy before surgery helps surgeons to choose an appropriate surgical method. This article reports the sinus floor elevation techniques used in three cases that showed anatomical variations and explains how different surgical methods are chosen when elevating the sinus membrane and increasing the vertical bone height, which is followed by implant placement.
