Ocular Reconstruction Using Bone-Anchored Implants in Irradiated Facial Deformities After Tumor Extirpation.

ABSTRACT

BACKGROUND: Surgical resection of ocular malignancies can result in complex craniofacial defects that can be difficult to reconstruct with conventional reconstruction techniques. Craniofacial prosthesis supported by bone-anchored implants has evolved as a reliable alternative in such scenarios. METHODS: The authors describe a patient who underwent extensive facial resection secondary to squamous cell carcinoma resulting in significant facial deformities. A bone-anchored osseointegrated implant was used to perform facial reconstruction. RESULTS: The patient had successful reconstruction of her orbit with bone-anchored implant. However, her implant needed to be removed 10 months postoperatively secondary to infection. A second attempt at implant placement has been deferred due to osteonecrosis secondary to adjuvant radiotherapy. CONCLUSION: Bone-anchored implants can provide an elegant alternative in the reconstruction of complex facial defects and provide direct access to surveillance for possible tumor recurrence. However, these bone-supported prosthetics should be used with caution in patients undergoing irradiation.
