The bone‐anchored auricular episthesis

Abstract

Total ablation of the pinna gives an unsatisfactory cosmetic result which has to be corrected. Plastic surgery procedures are generally not very successful and some sort of episthesis is preferred by many. The attachment of an episthesis is, however, often a problem. This paper is a case report of a new type of episthesis fixation arrangement. In a first session four titanium screws were implanted into the temporal bone above and behind the external meatus with a technique ensuring minimal tissue violation. Three months later when these screws were firmly integrated in the living bone, skin‐penetrating titanium abutments were connected and a gold bridge was adapted to the abutments. A silicon rubber episthesis was attached to the bridge with a snap fastener. Behind this new method of episthesis attachment are several years of clinical experience of titanium implants directly anchored into various living bones and allowed to permanently penetrate skin or mucous membrane.

Extraoral prostheses using extraoral implants

“…Craniofacial osseointegrated implants offer patients who wear facial prostheses a significantly improved quality of life 1,7,[21][22][23]25 . The advantages of extraoral implants are numerous, they provide consistent retention and positioning of the facial prosthesis and can be placed during the primary reconstruction procedure or anytime postoperatively when the patient can tolerate the procedure 4,7,21,22 .…”

“…The advantages of extraoral implants are numerous, they provide consistent retention and positioning of the facial prosthesis and can be placed during the primary reconstruction procedure or anytime postoperatively when the patient can tolerate the procedure 4,7,21,22 . In addition to providing predictable retention, several other important advantages were achieved 7 .…”

“…Osseointegration has been in clinical use in extraoral craniofacial sites since the 1970s [21][22][23] . Endosseous osseointegrated implants have greatly improved the potential for rehabilitating patients with extensive soft and hard tissue craniofacial defects 1 .…”

Prosthetics in Nasal Rehabilitation

“…Branemark and Tjellstrom in Sweden have pioneered the research and application of these new implants. 17 The theory is based on the fact that the outer layer of the Titanium implant appears to be recognized by the bone as a form of hydroxyapatite and the bone grows into the turns of the screw, - Figure 7.

Estudio Morfométrico de la Región Orbitaria para la Instalación de Implantes Craneofaciales

“…La primera investigación realizada para estudiar las técnicas asociadas a la instalación de implantes craneofaciales o fijaciones extraorales, destinadas a la rehabilitación protésica maxilofacial, fue realizada por Tjellström et al (1981) y consistió en la instalación de implantes en el área periauricular para aplicar una epítesis de oreja externa. A partir de esta experiencia, las técnicas de rehabilitación facial sobre implantes fueron indicadas a diferentes situaciones, como reconstrucciones posteriores a resecciones oncológicas, tratamiento de secuelas de trauma, tratamiento de malformaciones y deformidades faciales, entre otras (Tjellström et al, 1985, Wolfaardt et al, 2003.…”
