Despite the uncommon occurrence it is important to know the characteristics of the nasolabial cyst.
Left sided cyst was of size 3x2cm and right nasolabial cyst was of 2x2cm.
The aim of this article is to emphasize the importance of big rarely seen nasolabial cyst leading to facial deformity and infection seen in a 28 years old woman and to discuss its treatment by the analysis of the data in literature.
126 Our case had a giant nasolabial cyst with a size of 5x5cm and boat-like bone resorption caused by the cyst.
Gross examination of a nasolabial cyst resected in toto typically shows a spherical to oval, pink to tan, soft to rubbery-firm soft tissue mass with smooth surface.
To begin to investigate the molecular biology of this lesion, immunohistochemical examination of the protein expression profile of nasolabial cyst epithelium may be helpful.
Nasolabial cysts are usually unilateral, more common in women, usually present during the fourth and fifth decades of life, and have a predilection for the black population.
Treatment options for nasolabial cysts include needle aspiration, injection of sclerosing agents, cautery destruction, and incision and drainage.
3] The Nasolabial cyst is formed embryologically by detention cells from the inferior nasolacrimal channel endodermal cells  Exposure to trauma accelerates the formation of the cyst.
8] The nasolabial cysts can be marsupialized transnasally under the guidance of nasal endoscopes  Nasolabial cyst must be kept in mind in differential diagnosis of nasal vestibule, nasal base, and sublabial area.
In this article, we describe our retrospective analysis of the clinical appearance, pathologic findings, and treatment results in 18 cases of nasolabial cyst in order to assist the otolaryngologist in the diagnosis and treatment of this rare entity.
Eighteen patients were diagnosed with nasolabial cyst during the 12-year span between Jan.
It presented as an asymptomatic expansile lesion, which, when examined both clinically and with radiographical investigation, resembled a simple nasolabial cyst
The current recommended treatment of nasolabial cyst
is complete excision via sublabial Incision (5) which can be performed under LA (5), however we used general anaesthesia as the patient was anxious.
The favoured aetiological theory, posited by Bruggeman in 1920, suggests an origin from the remnant of the embryonic nasolacrimal duct, and is is supported by the fact that both the nasolacrimal duct and nasolabial cysts
are lined by the same pseudostratified columnar epithelium, and also by the fact that the cyst is located subjacent to the wing of the nose, in line with the naso-optic fissure.
