Determination of the Anatomical Features of the Temporal Bones at the Stage of Planning Extraoral Implantation in Ectoprosthetics of the Auricle

At the present stage of development maxillofacial surgery, treatment patients with defects in auricles is one most difficult. Defects auricles, characterized by its absence, are divided according to etiological factor into two main groups: congenital (microtia) and acquired (as a result injuries various origins). Microtia (including anotia complete absence auricle) malformation auricle external auditory canal caused anomalies first second zygomatic arch sulcus.Congenital malformations occur 1 out 700–15 000 newborns more often have right-sided localization. In 15 % cases, they hereditary, 85 sporadic, boys detected on average 2–2,5 times than girls.Currently, much attention paid prosthetic reconstruction fixation means cranial intraosseous implants. same time precise diagnostics state temporal bones area proposed implantation correct positioning supports basis an effective system. Among methods radiological used for planning ectoprosthetics radiography has long been preferred. However, introduction computed tomography clinical practice provided high-quality assessment state, which increased efficiency surgical intervention treatment.
