Complications and satisfaction with pediatric osseointegrated external ear prostheses.

OBJECTIVES

To determine the complication rate and the patient satisfaction of titanium osseointegrated ear implants for congenital microtia and anotia. To discuss external ear prostheses as a treatment option for children with microtia.

STUDY DESIGN

Retrospective chart review of patient records from a tertiary pediatric otolaryngology practice.

METHODS

The charts were reviewed for all pediatric patients who had undergone titanium implants for attachment of auricular prostheses from 2000-2006. Data collected included demographic information, congenital syndrome, number and size of screws placed, occurrence of skin reactions, presence of other complications, and length of time patients wore the prosthetic ear.

RESULTS

Eight patients, nine ears, were implanted. Median age was 7 years old. 6/8 had oculoauriculovertebral (OAV) syndrome, and 2 had isolated microtia. All titanium screws achieved complete osseointegration, and no implants have failed. 5/27 (18%) of the screws contacted dura, but no patients exhibited CSF leak, meningitis, or other central complications. 3/9 ears developed skin complications at the abutment sites, and 1/9 required revision soft tissue surgery. All the patients without current skin complications wear their prosthesis full time during waking hours.

CONCLUSIONS

Titanium osseointegrated ear prosthesis is a safe and useful procedure for children with microtia. It should be presented as an option for these patients, with low complication rates and high acceptance rates by the patients.
