Large Complex Odontoma in the Angulus Mandibulae - Intraoral Enucleation as an Alternative to Mandibular Continuity Resection.

ABSTRACT

BACKGROUND: Odontomas are among the most common odontogenic tumors and are generally considered as hamartomatous odontogenic lesions. These tumors can be histopathologically divided into complex odontomas and compound odontomas based on their composition. Odontomas show a slow growing behavior and typically lack characteristic symptoms. The standard surgical treatment for large odontogenic tumors is a mandibular (continuity) resection followed by primary or secondary plastic reconstruction. CASE REPORT A 22-year-old male presented to the Department of maxillofacial surgery with an increasing feeling of pressure in the left mandible. An orthopantomogram revealed a large complex odontoma rg 038. Instead of mandible continuity resection an alternative minimally invasive technique/approach (intraoral) with a trapezoidal bone flap for the enucleation of an odontoma of the mandibular angle with subsequent flap reimplantation and osteosynthesis was performed. CONCLUSION: Surgical enucleation of large mandibular odontoma with a continuity resection through an extraoral approach represents the surgical standard treatment of this entity. The present case report describes an alternative minimally invasive technique/approach. This technique may reduce surgical risks of the continuity resection through an extraoral approach (nerve damage, scarring) and can improve the long-term stability of the mandible by bone preservation.
