The functional and aesthetic reconstruction of midfacial and orbital defects by combining free flap transfer and craniofacial prosthesis.

OBJECTIVES

The reconstruction of complex facial defects should satisfy both aesthetic and functional requirements. In the midfacial area, the nasal passage should be sufficiently separated from the orbit and the oral cavity to avoid both dysphagia and articulation disorders and to allow unimpaired nasal breathing. In the case of large defects, the use of craniofacial prostheses alone is ineffective in the restoration of functional units in the majority of patients. Therefore, we evaluated the combination of microvascular tissue transfer and episthetic constructions in a series of patients.

MATERIAL AND METHODS

Our case series included ten patients requiring one or more free flaps in combination with extraoral implants and episthetic work.

RESULTS

Four women and six men with a mean age of 68 years were included. All patients were treated because of tumours in the midface area. Eight patients were free of recurrence, one patient died during the follow-up. For the reconstructions, we used anterolateral thigh flaps, radial forearm flaps, fibular flaps and iliac crest bone flaps. On average, we inserted four extraoral implants in the periorbital region. Seven implants of four patients did not osseointegrate and had to be removed.

CONCLUSIONS

For complex reconstructions of extensive defects in the midfacial area, microvascular free tissue transfer in combination with extraoral implants and craniofacial prosthetic work yields reasonable functional and aesthetic outcomes and noticeably improves the quality of life.

CLINICAL RELEVANCE

This work investigates patient cases with extensive defects in which free flap or episthetic work alone proved ineffective for reconstruction.
