Prosthetic Rehabilitation of an Orbital and Facial Defect: A Clinical Report

Abstract

For patients undergoing radical head and neck surgery, the deformity or physical defect adds to the agony. Rehabilitation of patients with such deformities is a challenge for the maxillofacial prosthodontist to enhance the esthetics and give psychological strength to the patient. This clinical report describes the rehabilitation, using a silicone prosthesis, of a large facial and orbital defect due to mucoepidermoid carcinoma.

Bone and Skin-Supported Stereolithographic Surgical Guides for Cranio-Facial Implant Placement

“…Facial prostheses retaining to anatomical and/or surgical undercuts; also retaining with mechanical aids have been still reported [3,[6][7][8][9][10][11]. Hatamleh et al [12] reported that, ocular prostheses included in their study were entirely retained by undercuts.…”

“…Additionally, weight reduction by using hollow prosthesis may contribute to the retention [5]. Already existing anatomical structures or undercut areas of the defect are employed to retain the facial prostheses conventionally [6][7][8]. Mechanical retention obtained by eyeglasses, straps or headbands, has been used for a long time [9][10][11].…”

A Review on Prosthetic Rehabilitation of Maxillofacial Region

“…The anatomy of the defect can be recorded accurately by rapid prototyping rather than conventional impression techniques to restore the facial prosthesis [46]. The advantage of maxillofacial prostheses is that, it requires less or no surgery as it restores the esthetics and function in a near natural appearance [13].…”

“…Impression tray is fabricated from a baseplate wax by warming it over the flame and adapting it around the contours of the eye. The location of the pupil is marked and a perforation with a diameter of 3-4 mm is made on the baseplate wax with many perforations in the surrounding wax [13]. Light body material is placed over the anatomical structure to be recorded and medium body impression material added.…”

“…Light body material is placed over the anatomical structure to be recorded and medium body impression material added. To stabilize the impression, before the impression sets ice cream sticks with heavy body impression material can be placed [13] (Figures 1a and 1b).…”
