Fibrous dysplasia.

Abstract

The controversy is this case centers around the management of this lesion, not the differential diagnosis. All the consultants agreed that the history, physical, and CT findings were consistent with various fibroosseous lesions, the most likely being fibrous dysplasia. The need for additional tests varied with a bone scan (Dr. Kearns), a bone scan and CT scan (Dr. McGill), and MRI, MRI angiogram, bone survey, BUN, creatinine, calcium, and phosphorus (Dr. Potsic). Cosmetic and functional changes were considered priorities for the consultants, with orbital compression, malocclusion, tooth eruption, nasal obstruction, and sinusitis (Dr. Kearns), nasolacrimal duct obstruction and orbital compression (Drs. McGill and Potsic) being the concerns. Because this lesion is benign and slow-growing, the consensus is that surgery should be reserved for functional or cosmetic compromise. But how aggressive should one be and what approach should be used? The approaches varied with midface degloving or lateral rhinotomy (Dr. Kearns), midface degloving (Dr. McGill), or a Caldwell-luc and lateral rhinotomy (Dr. Potsic). Assessment of this tumor postoperatively should be with patient examinations and serial CT scans. None of the consultants worried about sarcomatous changes in this tumor.
