Chondromyxoid fibroma (CMF) is a benign tumor which usually occurs in skeletal long bones. Its presence in zygoma is extremely rare. The patient was a 47-year-old female, with chief complaint of painful swelling in the left side of zygoma since 1 month ago after a long-lasting painless swelling for about 15 years. Computed tomography scan showed an osteolytic lesion, in the body of left zygomat...
PURPOSE The purpose of this clinical investigation was to evaluate the treatment outcome with zygoma implants with regard to implant survival, patient satisfaction, and function of prosthesis replacement after 3 years. PATIENTS AND METHODS The treatment outcome of 76 patients treated with 145 zygoma fixtures at 16 centers was evaluated with regard to implant survival. Status of peri-implant m...
PURPOSE The purpose of this study was to obtain anatomical information for installing four zygomatic implants, by measurements of maxillae and zygomata. MATERIALS AND METHODS Linear and angular measurements were obtained from the maxillae and zygomata of 40 dry skulls. RESULTS Based on mean and standard deviation values, the installation angle of the additional implant in the four zygoma te...
OBJECTIVE To evaluate sensorimotor nerve damage in patients with maxillofacial trauma referring to Taleghani hospital, Tehran, Iran. METHODS This cross-sectional study was conducted during a 2-year period from 2014 to 2012 in Taleghani hospital of Tehran. We included a total number of 495 patients with maxillofacial trauma referring to our center during the study period. The demographic infor...
In a 12-year period, 56 consecutive patients have undergone secondary periorbital reconstruction after trauma. To evaluate the overall results and the need for further correction, three diagnostic groups were formed. These were: malar bone (n = 16), midface (n = 16) and fronto-orbital fractures (n = 24). Also, in order to judge the reliability of the procedures used most frequently, all osteoto...
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...
Background: Pneumatized air cells present in the zygomatic process of the temporal bone are termed Zygomatic Air Cell Defects (ZACDs). They are merely the extensions of the mastoid air cells anteriorly into the zygomatic process of the temporal bone which are important for surgical perspective. Panoramic radiography is useful to display these zygomatic air cell defects. Aim: This study was unde...
Osteoma is a benign slow-growing osteogenic neoplasm commonly occurring in the craniofacial skeleton, characterized by the proliferation of compact and/or cancellous bone. Osteomas may be peripheral, central, or extraskeletal. Peripheral osteomas arise from the periosteum and are quite uncommon in the jaw bones. The exact aetiology and pathogenesis of peripheral osteoma are unknown. Clinically,...
