PURPOSE Facial crestal bone level and dimension determine function and esthetics of dentition and dental implants. We have previously demonstrated that ultrasound can identify bony and soft tissue structures in the oral cavity. The aim of this study is to evaluate the accuracy of using ultrasound to measure facial crestal bone level and thickness. MATERIALS AND METHODS A commercially availabl...

PURPOSE This cone beam computed tomography study (CBCT) evaluated horizontal and vertical dimensional changes to the facial bone following maxillary anterior single immediate implant placement and provisionalization. MATERIALS AND METHODS CBCT scans taken immediately after (T1) and 1 year after surgery (T2) were evaluated. The midsagittal cut of each implant was identified, and measurements w...

Simultaneous proptosis and facial palsy as the clinical presentation of childhoodAcute Myeloid Leukaemia (AML) is very rare. To date, no case have beenreported anywhere to the best of our knowledge. Extra medullary leukemic deposits or Granulocytic Sarcoma (GS) is a rare manifestation in about 3% of childhood AML, 9.3% of GS manifested as orbit deposits causing proptosis in one or both eyes. CN...

Introduction: Abnormal separation of CN7 much earlier in embryogenesis may be necessary for a bifurcation or trifurcation anomaly to result. Early division of the nerve at around 4-6 weeks may allow the displacement of one segment by the developing temporal bone structures.By the 8 th week, the orientation of CN7 within the temporal bone has been established, with nerve’s ultimate position and ...

The zygomatic bone is derived evolutionarily from the orbital series. In most modern mammals the zygomatic bone forms a large part of the face and usually serves as a bridge that connects the facial skeleton to the neurocranium. Our aim is to provide information on the contribution of the zygomatic bone to variation in midfacial protrusion using three samples; humans, domesticated dogs, and mon...

OBJECTIVES The purpose of this study was to inspect the clinical characteristics, surgical approaches, functional preservation, and complications of petrous bone cholesteatoma and to propose appropriate surgical approaches based on long-term follow-up cases and previous reports in the literature. METHODS The medical records of 31 patients who underwent surgery for petrous bone cholesteatoma b...

BACKGROUND Many studies have recently noted a shift in the causative mechanism of facial injuries away from traffic accident to assaults. AIMS Our study aimed to investigate patterns of facial injuries in trauma patients during 13 months study of trauma patients in six general hospitals in Tehran. MATERIAL AND METHODS Trauma patients who were hospitalized for more than 24 hours and had sust...

Bilateral facial paralysis is a rare clinical entity. It is also diagnostic challenge which, unlike unilateral facial paralysis, it is can be difficult to recognize because of a lack of facial asymmetry. A 22 year-old man referred for neurological evaluation because of bilateral facial paralysis (House-Brackmann grade V). He has initially presented unconsciousness after he sustained closed head...

In this report, we described clinical outcomes of a multi-stage surgery integrating multiple techniques in restoration of facial morphology and function of a 17-year-old boy with severe gunshot injuries. This multi-stage surgery was applied in treatment of one rare case of gunshot-caused complicated facial deformities involving most parts of the face (labrum, left nose wing, nasal columella, na...

Osteoporosis affects all bones, including those of the facial skeleton. To date the facial bones have not drawn much attention due to the minimal probability of morbid fractures. Hearing and dentition loss due to osteoporosis has been reported. New research findings suggest that radiologic examination of the facial skeleton can be a cost-effective adjunct to complement the early diagnosis and t...
