Nasolabial Cysts: Sublabial or Neumann Incision?

Abstract

Despite the fact that they are soft tissue cysts and are situated extraosseously they may sometimes cause bone destruction [4]. Differential diagnosis includes cysts of the nasopalatine duct, periapical inflammatory lesions (granuloma, cyst or abscess) and epidermoid or epidermal inclusion cysts [4]. The aims of treatment are to prevent infection, to establish a histopathological diagnosis, and to ameliorate a cosmetic deformity. Simple aspiration, injections with sclerosing agent, destruction by cautery, endoscopic marsupialization, needle aspiration and incision and drainage, have been described in the management of these cysts [3], but complete surgical excision of the nasolabial cyst is the best treatment [4]. The classical incision is sublabial. Usually the upper gingivolabial sulcus was incised just below the piriform apertures, and dissection exposed a smooth, well-circumscribed cyst swelling superficial to the lateral half of the bony floor of the nose [1,3]. In general, the cysts are easily dissected off, but dissection should be made carefully in order to avoid perforation and sensory damages. In this surgical approach, the incision coincides with the resection area, so that healing can lead to fistula and / or retraction pre maxilar.
