Bone lid technique to enucleate bilateral mandibular pindborg tumour

Calcifying epithelial odontogenic tumour (Pindborg tumour) is a rare benign neoplasm. It is an uncommon and locally invasive benign odontogenic tumor. The most characteristic findings are the presence of amyloid-like substance and calcified concentric liesegang rings. We report an unusual case of multifocal CEOT. A 24-year-old female presented with bilateral soft, erythematous, gingival swellings localized in posterior maxilla and mandible. Radiographic findings revealed that extended radiopaque regions related impacted teeth.

Enucleation of such large lesions can conclude extensive bone deficiencies. To eliminate such results enucleation was performed in the mandible with restoration of the surgical defect in the lateral wall. Cortical bone lid was prepared delicately and kept intact. After enucleation of the lesion bone lid was fixed with two mini plates according to anatomically proper position.

Advantages of the bone lid technique may be quick recovery and restored integrity of the lateral cortical wall, with a low probability of infection because of vascularization of the bone lid. Keeping the integrity of bone can block migration of epithelium into the large defect and constitute a framework for ossification. So bone volume could be shielded and hindered from large deficiencies after removal of extensive lesions.
