摘要
鼻唇囊腫是一種稀少的非牙源性囊腫，對於其來源雖然有些爭議，但目前普遍接受爲發育性囊腫。鼻唇囊腫病人，一般會有顔面腫脹、鼻翼隆起和鼻道阻塞的問題。無感染問題時，抽出鼻唇囊腫的液體，一般呈稻草色。在較大的鼻唇，有時可在X光片上，可見鼻底前緣及側緣位移和骨質破壞疏鬆。從口內摘除是其治療方式，大部分的鼻唇囊腫，都含有僞多層柱狀細胞，一般都不易復發。由於本病臨床症狀和其他疾病，如顔面蜂窩組織炎、齒源性疾病和鼻癤有相似的症狀，幫經常造成診斷上的困擾。本報告提出三例大小不同的鼻唇囊腫，個別敘述其不同的臨床症狀、不同的X光特徵，以增加對鼻唇囊腫的瞭解，提供病人適當的治療。

鼻唇囊腫並列摘要
The nasolabial cyst is a rare non-odontogenic cyst. Although its pathogenesis is controversial, most clinician today believe it to be a fissural cyst. Patients with this lesion usually present with swelling, nasal ala elevation and obstruction of nasal cavity. A spiration of the cystic content shows straw-color fluid. Occlusal radiography revealed displacedment of the anterior and lateral edges of the nasal floor and bone rarefaction in the case of large nasolabial cyst. Surgical excision through sublabial approach is appropriate treatment of choice. No case of recurrence was reported in the previous literatures. Most nasolabial cysts contain pseudostratified columnar epithelium. Clinically it mimics facial cellulites, periapical abscess or nasal furuncle and which mimicry may bring about diagnostic challenge. The report presents 3 cases of nasolabial cysts of different sizes. They show different clinical signs, different radiographic signs and histopathologic character individually. The objective of this paper is to increase readers' understanding of the nasolabial cyst with the aim of expecting to avoid and overcome diagnostic challenges.
