desmoplastic fibroma (df) is a rare and locally aggressive intraosseous tumor with unknown etiology. the mandible is the common site of involvement in the maxillofacial region. however, it is believed that df can arise in any bone of the body. a wide age distribution has been reported for df occurrence, extending from birth to the sixth decade of life, with a peak incidence at 10 to 19 years of...

clusions often requires intrusion and retraction of the anterior segment, which, in turn, usually necessitate mechanical reinforcement of posterior anchorage.1 Intraoral devices such as transpalatal bars or Nance appliances2 can reduce the need to wear Class II elastics, but can cause mesial movement of the lower first molars and protrusion of the incisors. Additional extraoral anchorage in the...

The Maintenance of Certification module series is designed to help the clinician structure his or her study in specific areas appropriate to his or her clinical practice. This article is prepared to accompany practice-based assessment of preoperative assessment, anesthesia, surgical treatment plan, perioperative management, and outcomes. In this format, the clinician is invited to compare his o...

The zygoma forms part of the floor and lateral wall of the orbit and the zygomatic arch is an important feature in the structure and appearance of the face. The malar complex refers to the zygoma and maxillary bones (and therefore forms part of the orbital floor and lateral orbital wall). This plays a key role in the structure and function of the facial skeleton. In addition to providing suppor...

Ewing's sarcoma is a malignant, small, round cell neoplasm that normally affects the long bones of the limbs or the pelvis. It is a relatively frequent malignant bone tumor in children. The occurrence of the primary tumor in the facial region is approximately 2%, with most of the cases affecting the mandible. Primary zygoma involvement is rare and as per the available literature only three case...

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...

BACKGROUND Currently, there is a greater use of nonlethal force in law enforcement and military operations. Because facial injuries have been observed, there is a need to understand the human response to ballistic impacts involving various regions of the face. This study aimed to establish blunt ballistic response corridors for high-speed, low-mass facial impacts to the forehead, zygoma, and ma...

OBJECTIVE Successful prosthetic rehabilitation is crucial for quality of life in cases of large maxillary defects when surgical reconstruction is not advisable because of general health or patient refusal. For this purpose, the extended indications for Zygomaticus fixtures in different defect types were evaluated. PATIENTS AND METHODS Twelve patients received 28 zygoma implants and 23 dental ...
