Osteoplastic resection of an osteoma of the paranasal sinuses with reconstruction by CAD-implant

Introduction:

Osteoma are the most frequent benigne tumors of the paranasal sinuses. They often appear as incidental findings or become symptomatic because of disturbed drainage or intraorbital or even intracranial extent. In some cases extensive or symptomatic osteoma need to be resected using special reconstructive methods.

Case report:

A 50-year-old patient complained about increasing diplopic images, pressure on the right eye and headache. The clinical examination showed a lower standing eyeball on the right side and restriction of the motility when looking up. The cranial CT showed an osteoma of 4.3 × 2.8 cm extending to the frontal sinuses, to the ethmoidal cells and to the right eye socket. After en bloc resection the bone defect was reconstructed by CAD-implant (computer assisted device) made of hydroxylapatite. Aftercare showed a satisfying outcome with both functionally and cosmetically good results. Normal vision was preserved with both adequate position and normal motility of the eyeballs.

Conclusion:

CAD-implants made of hydroxylapatite are well planable and intraoperative safely usable devices for reconstruction of bone defects concerning resected osteomas of the paranasal sinus. They also have good osseointegrative qualities.
