INTRODUCTION The literature has demonstrated that alterations in craniofacial morphology characterizing individuals with cleft palate are observed in both operated and unoperated patients. OBJECTIVE This study evaluated the influence of isolated cleft palate and palatoplasty on the face, based on facial analysis. MATERIAL AND METHODS Lateral facial photographs of the right side of 85 young ...

Presurgical planning is essential to achieve esthetic and functional implants. For implant planning and placement, the association of computer-aided design (CAD) and computer-aided manufacturing (CAM) techniques furnishes some advantages regarding tridimensional determination of the patient's anatomy and fabrication of both anatomic models and surgical guides. The goal of this clinical study wa...

BACKGROUND To let experts evaluate a single surgeon's experience with a combined transconjunctival and intraoral upper vestibular approach in the repair of zygomatic fractures encountered in 46 East Asian patients whom he treated over the past 20 years. METHODS Patients were identified from a database, and a retrospective case note review was conducted. A total of 67 conjunctival and secondar...

It has been the aim of the present study, to introduce the combination of computed tomography and optical 3D imaging to exophthalmometry and to compare the resulting data to the classic Hertel method. Twenty patients without orbital pathology and 12 patients were included in the study, who were subjected to a preoperative computed tomography. Optical 3D images of the facial surface were assesse...

The Purpose of this study To document the etiology and clinical data of patients with fractures of the zygomatic complex and to compare the findings with other studies in the literature Patients and Methods: This crosssectional study was performed from January 2011 to December 2012, One hundred and sixty patients with zygomatic fracture were admitted to Oral & maxillofacial department of Imam R...

The results of experimental studies on the zygomatic arch during the growth period, through excisions or fractures, are controversial. In this study, the effect of a discontinuity of the zygomatic arch on facial growth was experimentally evaluated, without tissual damage or deviations. One-month-old rats were submitted to a surgical procedure in order to obtain a one-milimeter-wide discontinuit...

The aim of the study was to assess the incidence, etiology and spectrum of zygomatic bone injuries sustained during sports treated at the Department of Maxillofacial Surgery, using the retrospective database between 2002 and 2012, as well as to suggest protective measures. The ratio of males (95%) to females ( 5%) was 19:1.The highest incidence was at age between 11-30 years. The study indicate...

The purpose of this study was to analyze changes in the internal structure of zygomatic bone using a micro-finite element analysis model (muFEA) and compare angular orientation of trabeculae against compressive force in edentulous and dentulous jaws. Twenty zygomatic bones from dentulous jaws and 20 zygomatic bones from edentulous jaws harvested from Japanese male cadavers were used. From 2-dim...

BACKGROUND Zygomatic implants are an alternative treatment in the rehabilitation of atrophic maxilla to promote stability in the stomatognathic system. The aim of this study was to compare the electromyographic (EMG) activity of masseter and temporalis muscles in controls and in individuals with complete implant-supported dentures anchored in the zygomatic bone. MATERIALS AND METHODS Fifty-fo...

BACKGROUND Variable methods have been introduced for reduction of the zygomatic fractures. The Dingman elevator is used widely to reduce these fractures but is inappropriate in certain types of fractures which require atypical traction vectors. We introduce and examine an alternate method of reducing zygomatic fractures using wire and hook traction. METHODS A retrospective study was performed...
