Intraoral endoscopic enucleation of a solitary bone cyst of the mandibular condyle.

Solitary bone cysts are benign osteolytic lesions rarely involving the mandibular condyle. They are considered pseudocysts due to the absence of epithelium and their pathogenesis is unknown. These lesions are also known with a variety of synonyms, such as traumatic bone cysts, simple bone cysts, haemorrhagic bone cysts and unicameral cysts. The authors report a case of a solitary cyst of the condylar head treated by enucleation and curettage via an intraoral endoscopic-assisted surgical approach, which avoids the risk of facial nerve injury, reduces the patient's hospitalization and speeds up functional recovery
