Endoscope-assisted enucleation of mandibular dentigerous cysts

We demonstrate a reliable and minimally invasive treatment with endoscopically-assisted surgery for enucleation of a posterior mandibular dentigerous cyst with an intraoral approach. A 28-year-old Japanese man had a bilateral mandibular dentigerous cyst that was contiguous with the third molars. Surgical enucleation of the cyst was performed with an endoscope-assisted field of view. The alveolar nerve was identified endoscopically, and continuity of the nerve was carefully preserved. In addition, it was clearly confirmed in the endoscopic visual field that the root apex of the mandibular second molar was not completely exposed. The use of an endoscope made it possible to clarify the operative field and to preserve the surrounding tissues. Surgery in the mandible was safer and less invasive with endoscopic assistance than it would have been without such assistance.
