Partial ostectomy and contouring

If the disease is limited to a small anatomic area one may also choose a partial excision with the hope that the disease will burn out over time and not recur.

If the disease is extensive and involves large anatomical areas, which would be difficult or risky to resect and reconstruct, contouring and reduction of the bone volume is recommended.

Approaches depend on the affected anatomical area. The following approaches may be useful:

• Lower eyelid - transconjunctival
• Lower eyelid - transcutaneous
• Coronal approach
• Buccal sulcus approach
• Transoral approach to chin
• Transoral approach to lateral mandibular body

Contouring and reduction of the bone volume is typically done with a combination of osteotomes and burrs and can be applied to any anatomical area: frontal bone maxilla, orbit, and mandible.

Extensive fibrous dysplasia involving left maxilla, nose and zygoma.

Transoral partial ostectomy and contouring was performed.

Post-operatively the facial contour is normalized without radical resection and preservation of anatomical structures.

Aftercare involves antibiotics, standard mouth care with early return to function and eating.
