Nasolabial cyst is non odontogenic cyst, 90%unilateral, 10% bilateral. Theories of original are:

 1. Epithelial remnants of nasolacrimal duct.

2. Embryological detention from effusion of the epithelial of medial and lateral frontonasal process with maxillary process.

3. Possible trauma accelerating its formation.

Our case: 50yrs old female presented with 12 months of slow asymptomical swelling under left upper lip became tender for the last 2 moths, with increasing of nasal obstructions in the same side.

Symptoms/ Signs of nasolabial cysts: few cases are asymptomatic, most are presents:

1.Partial nasal obstruction 62.5%

2.Localised swelling in the nasal vestibule 50%.

3.Painful swelling (when infected 25%.

Diagnosis: MRI, CT scans (rounded homogeneous low density soft tissue.

Treatment: surgical excision

Trans nasal endoscopic marsupialization

PROS: Less pain, local anaesthesia.

CONS: small opening, fewer complications, recurrence.

Sublabial surgical excision.

PROS: effective method, faster recovery, can be done under GA, LA.
