Custom Maxillofacial Prostheses Restore Function for Patients

Addressing an extreme case


Rehabilitation of patients with head and neck defects or disabilities caused by development, trauma or disease requires specialized care among several disciplines.

Adults and children with melanoma or carcinoma, birth defect patients with craniofacial deformities (specifically microtia), and car accident patients suffering orofacial injuries often need the comprehensive skills of a team of specialists in Cleveland Clinic’s Head & Neck Institute, including neck surgeons, oral surgeons, general and specialty dentists. They often work with plastic surgeons, radiation oncologists, speech language pathologists and anaplastologists to restore form and function – and a sense of normalcy – to patients with intraoral and extraoral defects.

Maxillofacial Prosthodontic Clinic

The teaming of Sanjay Karunagaran, DDS, MSD, a prosthodontist, and Theodore R. Arlotto, MAMS, an anaplastologist, in the Maxillofacial Prosthodontic Clinic in the Head & Neck Institute provides a unique skill set in creating custom prostheses to replace missing areas of bone or tissue that can restore oral function, such as swallowing, speech and chewing.

“Patients with intraoral or facial issues are interested in getting back to a more normal existence – being able to eat, talk normally, go out in public and interact with people,” Arlotto says. “It can be a self-confidence booster. Someone who doesn’t want to go back to work because they lost an ear or an eye can get a prosthesis that can help them get back out in the world and living a more normal life.”

Reconstructing What Surgery Can’t

Dr. Karunagaran says he sees patients on the extreme end of the spectrum who require specialized care.

Extraoral prostheses can include ocular, orbital, auricular, nasal and midfacial prostheses. Intraoral prostheses can include:

  • Surgical obturator prosthesis, which covers the palate after partial or total loss of the maxilla
  • Interim and definitive obturator, which covers the palate after partial or total loss of maxilla due to cleft palate, restores teeth and gums, and closes the defect or hole to facilitate swallowing, eating, chewing and speaking
  • Palatal lift prosthesis, which provides correct positioning of the soft palate for speech
  • Palatal augmentation prosthesis, which alters the palatal position for speech
  • Mandibular resection prosthesis, which replaces a portion of the jaw and restores gum and teeth for improved mastication and facial esthetics

“Many patients can’t be reconstructed surgically,” Dr. Karunagaran says. “While surgery can do a lot of things, in order for some patients to be fully functional they need a prosthetic.”


Case Study: Nasal Prosthetic

In one recent case, a patient came in for a prosthodontic dental procedure when the team noticed he was missing a nose from previous treatment for squamous cell carcinoma of the nasal cavity. The nose was resected and followed up with radiation therapy.

The patient avoided wearing his original prosthesis because it was too large, the coloring was off and he had difficulty keeping his glasses on his face. As a result, he rarely wore the device, opting for a bandage over the defect and avoiding public appearances.

Dr. Karunagaran and Arlotto worked with the patient to create a prosthesis that extended back into the defect site and locked into the undercut areas for retention.

“We were able to work with the natural shape of the tissue and design a prosthesis that can be locked in place without adhesive,” Arlotto says. The prosthesis was custom stained and colored to fit the patient’s existing skin tone, resulting in a happy patient who wears the prosthesis in public and reports improvement in his physical and mental well-being.


The Process

The process works by taking impressions of the defect site, molding a wax prototype, making adjustments based on patient feedback, and creating the final silicone prosthetic. The timeline for completion varies form case to case, but extraoral prostheses can take months to create and refine, while intraoral prostheses can take up to two years for completion. Ocular prostheses, for example, can be completed in three to four weeks, while a facial prosthesis can take four to seven weeks.

Follow-up depends on the patient’s needs. A patient receiving a prosthesis for the first time, or who has little support at home, may require multiple appointments and fittings, while someone who has had a prosthesis in the past will need less follow-up care.

While Dr. Karunagaran and Arlotto tend to see patients after surgery, they say meeting with a patient after diagnosis, but prior to surgery, provides the ability to pull an impression from an ear or nose and create a prosthesis that closely matches the natural face. When that isn’t possible, Arlotto works from photographs or tries to match the non-affected orbit or ear.

“There are many people who need these extra oral devices to help them gain their confidence and happiness so they are able to function normally in society,” says Dr. Karunagaran. “Many times, patients are not aware that our team is here and doing this type of work. Our goal is to make more physicians and patients aware of the service we provide.”
