SUCCESSFUL SURGICAL MANAGEMENT OF THE LARGE RADICUALAR CYST WITH THE COMPRESION OF MENTAL NERVE AND RISK OF THE MANDIBLE FRACTURE

Abstract

Radicular cysts are the most common inflammatory odontogenic cysts, typically associated with non-vital teeth and often resulting from untreated or inadequately managed endodontic infections. Although they are usually small and asymptomatic, larger lesions may cause significant bone destruction and involve adjacent anatomical structures.

We report a case of a large radicular cyst in the mandible associated with a previously inadequately treated tooth.
The lesion exhibited extensive bone resorption, resulting in cortical thinning and increased risk of pathological mandibular fracture.
Notably, the cyst was associated with compression of the mental nerve, leading to sensory disturbances.

The patient was managed surgically by complete enucleation of the cyst with careful preservation of the mental nerve.
Postoperative recovery was uneventful, with resolution of symptoms and satisfactory bone healing observed during follow-up.

This case highlights the importance of early diagnosis and adequate endodontic treatment in preventing the progression of radicular cysts to advanced stages.

It also emphasizes the need for careful surgical planning when managing large lesions associated with nerve involvement and structural weakening of the mandible.
