Simultaneous ipsilateral temporal fossa and orbital dermoid cysts.

PURPOSE: To describe a case of simultaneous dermoid cysts in the lateral orbit and temporal fossa. DESIGN: Interventional case report. METHODS: A 7-year-old boy with a lateral orbital mass and infratemporal fossa mass underwent computed tomography and surgical excision. RESULTS: Intraoperatively, two distinct cystic lesions were identified. The orbital lesion extended just beneath the lateral rim. The temporal fossa lesion extended posteriorly along the temporal fossa. No bony defect in the lateral orbital wall was identified, and each distinct lesion was completely excised. CONCLUSIONS: To our knowledge, this is the first reported case of multiple dermoid cysts in the orbital region. When imaging studies demonstrate separate cystic lesions and do not reveal a bony defect in the lateral orbital wall, multiple lesions should be suspected.

Bovine hydroxyapatite orbital implant: a preliminary report.

PURPOSE: To determine the safety and efficacy of bovine hydroxyapatite as an orbital implant material. METHODS: Prospective, consecutive case series of patients undergoing enucleation, evisceration, or secondary orbital implantation. A motility peg was placed in all consenting candidates. Patients were followed 1 week, 1 month, and several months after surgery for signs of inflammation, infection, extrusion, or other complication. RESULTS: Twenty-seven patients received a bovine hydroxyapatite orbital implant. Magnetic resonance imaging was obtained in 3 patients (3 orbits) approximately 4 weeks after surgery and showed signs of peripheral fibrovascular ingrowth in all three cases. Magnetic resonance imaging was obtained in 9 patients (9 orbits) 4 to 12 months after surgery and showed signs of incomplete fibrovascular ingrowth in 1 of 9 (11%) cases, subtotal fibrovascular ingrowth in 2 of 9 (22%) cases, and complete fibrovascular ingrowth in 6 of 9 (67%) of cases. Complications included postoperative chemosis in 3 cases (11%) and exposure requiring reoperation in 2 cases (7%). Motility peg placement was performed successfully in 5 patients (5 orbits). CONCLUSIONS: Bovine hydroxyapatite appears to be a safe and effective orbital implant material. The material appears to be biocompatible and nonallergenic. Bovine hydroxyapatite allows for fibrovascular integration and motility peg placement.

A new algorithm for ptosis repair using conjunctival Müllerectomy with or without tarsectomy.

PURPOSE: To determine the predictability of a new algorithm for determining the amount of tissue resection for conjunctival Müllerectomy with or without tarsectomy blepharoptosis repair. METHODS: Consecutive case series of all patients undergoing conjunctival Müllerectomy with or without tarsectomy ptosis repair from October 1999 to September 2001. Each patient underwent excision according to a new algorithm for determining the amount of tissue excision. The amount resected was determined by the following formula: 9 mm of conjunctiva and Müller muscle + x mm of tarsus, where x = distance of undercorrection after phenylephrine testing. RESULTS: Sixty-eight consecutive patients underwent 70 cases of conjunctival Müllerectomy with or without tarsectomy ptosis repair on 117 eyelids, using a new algorithm for tissue excision. Forty-seven cases were bilateral and 23 were unilateral. Postoperative symmetry was found in 58 of 67 patients (87%) after 1 surgery. Patient satisfaction based on symmetry, contour, and height after 1 repair was achieved in 64 of 67 patients. There were no overcorrections. Two patients underwent successful reoperation with a second conjunctival Müllerectomy with or without tarsectomy operation. CONCLUSIONS: This modified algorithm and technique quantifies conjunctival Müllerectomy with or without tarsectomy ptosis surgery and yields predictable results.
