Use of Orbital Conformer to Improve Speech in Patients with Confluent Maxillectomy and Orbital Defects

Abstract

The basic objective in prosthetic restoration of confluent maxillary and orbital defects is to achieve a comfortable, cosmetically acceptable prosthesis that restores speech, deglutition, and mastication. It is a challenging task complicated by the size and shape of the defects. The maxillary obturator prosthesis often satisfies the objective of adequate deglutition; however, orbital defects that are not obturated in the medial septal or posterior walls allow air to escape, negatively impacting phonation. This article describes a technique to achieve favorable prosthetic rehabilitation in a patient with a maxillectomy and ipsilateral orbital exenteration. The prosthetic components include maxillary obturator, orbital conformer, and orbital prosthesis connected using rigid magnetic attachments.

Prosthetic rehabilitation of resected orbit in a case of mucormycosis

“…The mechanical undercut created in the conformer overcomes the limitation of loss of retention over time, as may be seen with magnetic elements. [6] The technique is less expensive, avoids a surgical intervention and does not require a traditional waiting period as needed (for osseointegration) when compared with implant-supported prosthesis. [113] This can be considered favorable for patients who can overcome the psychological trauma of social ostracism sooner with the design of the prosthesis described.…”

“…The design of an orbital prosthesis to rehabilitate a patient with orbital exenteration depends on several factors including the underlying clinical status (extent of resection of orbital contents and risk of recurrence of pathology), preference of the patient (determined by affordability and dexterity to use the prosthesis), material chosen for fabrication, and the method of retention of the prosthesis.

Rehabilitation after severe maxillectomy using a magnetic obturator (a case report)

“…Use of magnetic prostheses may also cause some difficulties for patients, which should be thoroughly explained and discussed with them. Magnets need replacement over time and the patient should be fully aware of their costs and should be provided with instructions on how to protect the prosthesis …”

“…Magnets need replacement over time and the patient should be fully aware of their costs and should be provided with instructions on how to protect the prosthesis. 21 Another problem faced by patients with maxillary defects is the relatively high weight of the prosthesis due to large amounts of acrylic resin used to fill the defect and also for the fabrication of hollow-bulb obturator. However, patients get used to it over time.…”
