Medication-Related Osteonecrosis of the Posterior Maxilla: Surgical Treatment Using a Combined Transnasal Endoscopic and Intraoral Approach, our experience with seven consecutive patients

Abstract

Upper jaw MRONJ if not correctly treated can lead to serious complication.

Upper jaw MRONJ is frequently associated with maxillary sinusitis, the disease can spread to other paranasal sinuses.

Combined approach is the most reliable procedure to treat odontogenic sinusitis; although MRONJ associated sinusitis is considered odontogenic there is no report in literature describing combined approach to treat MRONJ-induced sinusitis.

Buccal fat pad represents the best reconstructive option to close the bony defect.

BFPF does not allow rehabilitation through dental implant since it is adipose tissue and not bone tissue. However, guidelines do not recommend implant-supported prosthetic rehabilitation in patients with history of MRONJ so conventional dental rehabilitation should be carried out.
