BACKGROUND Nasolabial cysts are rare, non-odontogenic, soft-tissue cysts that develop between the upper lip and nasal vestibule with an overall incidence of 0.7% out of all maxillofacial cysts. The predominant presentation of a nasolabial cyst is a painless localized swelling with varying degrees of nasal obstruction. Several treatment modalities have described in the management of the nasolabial cyst. In this paper, we present a case of a nasolabial cyst in a 44 years old man with discussions of the treatment modalities in the lights of the literature. CASE PRESENTATION We present a case of a nasolabial cyst in a 44-year-old man that slowly increased in size through a period of 3 years, with associated mild pain and nasal obstruction. It had caused a mass effect upon the maxilla, resulting in scalloping. The cyst was excised entirely with no evidence of recurrence at the two months follow up. CONCLUSIONS The nasolabial cyst is a rare soft-tissue cyst. Complete surgical excision using an open approach performed to our case, which considered with the complete endoscopic removal of the best treatment for the nasolabial cysts with a rare recurrence rate.

鼻唇囊肿：病例报告和治疗方案回顾。

背景鼻唇囊肿是罕见的，非牙源性的软组织囊肿，在上唇和鼻前庭之间发展，总发病率占所有颌面部囊肿的0.7％。鼻唇囊肿的主要表现是无痛性局部肿胀，鼻塞程度不同。在鼻唇囊肿的治疗中已经描述了几种治疗方式。在本文中，我们介绍了一名44岁男性鼻唇囊肿病例，并根据文献讨论了治疗方式。病例介绍我们介绍了一个病例，该病例为一名44岁男性鼻唇囊肿，其大小在3年内逐渐增大，伴有轻度疼痛和鼻塞。它在上颌骨上造成了肿块效应，导致扇贝。在两个月的随访中，完全切除了囊肿，没有复发的迹象。结论鼻唇囊肿是一种罕见的软组织囊肿。对我们的病例采用开放的方式进行完全手术切除，考虑通过内镜完全切除鼻唇囊肿的最佳治疗方法，复发率极低。
