In1920, Bruggemann, arises in the lower part of nasolacrimal ducts.In 1969 Roed-Petersen, nasolacrimal duct are lined by pseudostratified columnar epithelium .In 1993,Klestadt suggested, they arise from junction of the globular process, the lateral nasal process and the maxillary process as a result of proliferation of entrapped epithelium along the fusion line.
Nasolabial cyst is a non-odontogenic, soft tissue cyst characterized by its extra osseous location in the nasal alar region. It is synonymous with nasoalveolar cyst, nasal vestibule cyst, nasal wing cyst and mucoid cyst of the nose.Etiopathogenesis:Two theorieshave been suggested to explain the origin of nasolabial cyst.
Klestadt in 1993 suggested that they arise from trapped epithelium at the point where the maxillary, medial nasal, and lateral nasal processes fuse which become inclusion cyst. However, a lack of evidence to support the idea of embryonic epithelial entrapment in this location prompted many researchers to discard this hypothesis.Bruggeman in 1920 had suggested that nasolabial cysts develop from remnants of the embryonic nasolacrimal ducts. This theory is supported by the fact that the nasolacrimal ducts are lined with pseudostratified columnar epithelium, which is the type of epithelium found in the nasolabial cyst cavity.
