Infectious Osteonecrosis of the Maxilla

Two patients are presented with maxillary bone loss and atelectasis of the sinus walls in association with chronic subclinical maxillary sinusitis. Maxillary sinus atelectasis results in a mild cosmetic deformity, but may also cause diplopia by involving the orbital floor. Ostial obstruction and inflammation-mediated osteopenia are postulated to be the responsible mechanisms. Surgical treatment of the sinusitis may prevent progression of the bone loss.

A wide spectrum of diseases may involve the clivus, such as primary neoplasms, metastatic disease, and inflammatory, vascular, hematopoietic, and infectious processes. Of these, osteomyelitis of the skull base and/or clival-petrous abscess are unusual, but may occur as a result of contiguous spread from the paranasal sinuses, namely, the posterior ethmoid and sphenoid, as was demonstrated by this patient. In this case report we discuss the pertinent anatomy, imaging studies, pathogenesis, and medical and surgical management of this case.
