Coronoid-condylar index in assessing of mandibular coronoid hyperplasia. Preliminary results

PURPOSE The purpose of this study was to define the coronoid-condylar index (CCI). MATERIALS AND METHODS The material for studies comprised 26 patients. Thirteen patients were treated for bilateral coronoid hyperplasia. The remaining 13 patients were included in the control group. Based on 3D CT measurements, the coronoidcondylar index (CCI) was calculated and assessed statistically. RESULTS In patients with coronoid hyperplasia mean CCI was 1.25, while in the control group it was 1.00. CONCLUSION The proposed CCI can be used for the evaluation of anomalies of the mandibular coronoid processes.

Three-layered osteodural plasty for severe anterior skull base and facial injuries. Report of eleven cases

BACKGROUND AND PURPOSE The upper cranial trauma of high force and wide area of application leads to fractures of calvaria, the skull base, and the viscerocranium. The aim of the study was to present eleven patients treated for severe anterior skull base and facial defects by means of three-layered osteodural plasty. MATERIALS AND METHODS The operative tactics consisted of bicoronal incision, bifrontal craniotomy, closure of the dura mater damage with a pericranium, reconstruction of bone defects with autologous bone grafts and plasty with anteriorly pedicled pericranial flap on the supratrochlear and supraorbital vessels. RESULTS During follow-up, which lasted 2-7 years, none of the patients developed any early or late postoperative complications. CONCLUSIONS The three-layer osteodural plasty of severe anterior skull base injuries with the use of autologous bone grafts for the reconstruction of craniofacial skeleton resulted in a good final functional, morphological and aesthetic outcome in all patients.
