Nasolabial cyst: diagnosis mainly based on topography?

Area of Science:

• Oral and Maxillofacial Surgery
• Dermatology
• Pathology

Background:

• Nasolabial cysts are rare developmental cysts.
• Their etiology remains debated, with fissural cyst classification being most accepted.
• Consistent nomenclature is lacking.

Observation:

• Three cases of nasolabial cysts are presented.
• The hallmark clinical sign is a smooth, fluctuating swelling in the nasolabial fold.
• Histopathology and cytology have limited diagnostic value.

Findings:

• Clinical presentation is the primary diagnostic criterion.
• Computer tomography (CT) and echography aid in assessing lesion extension and preoperative planning.
• Nasolabial cyst is the preferred term due to its topographical description.

Implications:

• Accurate diagnosis relies heavily on clinical examination.
• Advanced imaging techniques like CT and echography improve surgical planning.
• Surgical excision via an intraoral approach ensures excellent patient outcomes.
