Surgical Correction of Proptosis in Craniofacial Benign Bone Lesions Involving the Orbit.

Abstract

Craniofacial bone lesions involving the orbit are often associated with symptoms, including proptosis, orbital dystopia, and overall facial asymmetry. Fibrous dysplasia and osteoma are the 2 most commonly observed bone tumors in the craniofacial area. Nine patients with either craniofacial fibrous dysplasia or osteoma and an unacceptable aesthetic appearance were treated from January 2015 to July 2016. All patients underwent preoperative craniofacial 3-dimensional computed tomographic (CT) scanning, and standard photographs were obtained. Proptosis measurements were performed on CT images using an annotation ruler provided by the imaging system both pre- and postoperatively. All patients were treated surgically, and a coronal incision was used. Outcomes were assessed by CT scans, and photographs were obtained during routine follow-ups at 1 week, 3 to 6 months, and 1 year after surgery. The Likert scale was used to investigate patients' postoperative satisfaction rate. Favorable outcomes were achieved in all patients. The mean difference between eyeball proptosis was reduced from 3.6 mm before surgery to 1.6, 0.6, and 0.3 mm after the surgery at 1 week, 3 to 6 months, and 1 year, respectively. No complications, such as facial and/or optic nerve injury, recurrence, and malignant degeneration, were noted. This study demonstrated that surgical treatment of craniofacial bone lesions involving the orbit achieved acceptable results shortly after the surgery, and more prominently, starting from 3 to 6 months.
