Endoscopic Dentigerous Cyst Removal Surgery done by Dr.Meenesh Juvekar, Bombay Hospital, Mumbai
A dentigerous cyst or follicular cyst is an odontogenic cyst - thought to be of developmental origin - associated with the crown of an unerupted (or partially erupted) tooth. The cyst cavity is lined by epithelial cells derived from the reduced enamel epithelium of the tooth forming organ
Dentigerous cysts are usually easy to treat when small. However, extensive cysts are more difficult to manage requiring cyst enucleation and extraction of associated teeth.
Cyst enucleation without extraction of the impaction, and decompression are two treatment modalities indicated in growing children and adolescents to salvage the involved dentition.
The usual radiographic appearance is that of a well-demarcated radiolucent lesion attached at an acute angle to the cervical area of an unerupted tooth. The border of the lesion may be radiopaque.
The most common location of dentigerous cysts are the Mandibular 3rd Molars and the Maxillary Canines, and they rarely involve deciduous teeth and are occasionally associated with odontomes.
Surgery is commonly recommended for dentigerous cysts because they often block eruption of teeth, become large, displace teeth, destroy bone, encroach on vital structures (ie encompass or displace the alveolar nerve, shrink the maxillary sinus) and occasionally even lead to pathologic fracture.Surgical approach is done by Caldwell Lucs approach as seen in this video.
This treatment has however, classically consisted of cyst enucleation and extraction of the tooth or teeth embedded in it, or impacted by it.
This treatment option although favourable in cases involving a single impaction .
