Frontal bone and modified zygomatic implants for retention of a nasal prosthesis: Surgical planning using a three-dimensional computer software program

Abstract

Implants integrated into bone have revolutionised the retention of total nasal prostheses. However, it may be difficult to identify available sites for placement of the implant after excision. In addition, it is ideal to minimise wide bony exposure after radiotherapy to avoid compromising the blood supply. In this paper we describe a technique for accurate placement of frontal bone and customised zygomatic implants using a computer-designed and fabricated surgical guide with a minimal access flap.
