Foreign bodies are often encountered by oral and maxillofacial surgeons and may present a diagnostic challenge to the trauma surgeon due to many factors such as the size of the object, the difficult access, and a close anatomic relationship of the foreign body to vital structures. They are usually a result of injuries or operations. Fragments of broken instruments can be left behind and entire teeth or their fragments can be displaced during extraction. ⋯ With a view to illustrating and discussing the diagnosis and treatment of this kind of injury, this study reports impacted foreign bodies in oral and maxillofacial region. The following data were collected: age, sex, race, etiology, occurrence of fracture, anatomic location of the fracture, daytime of the traumatic event, type of the object, signal and symptoms, type of imaging examination used, type of anesthesia, approach, transoperative complication, period between surgery and hospital liberation, and the occurrence of death. Foreign body injuries in the maxillofacial region can place the patient's life at risk, so a correct initial treatment performed by a multidisciplinary team increases the survival of this kind of patient.

Review Case Reports
Salvage of calvarial bone graft using acellular dermal matrix in nasal reconstruction and secondary rhinoplasty for frontonasal dysplasia.
Frontonasal dysplasia is a severe malformation composed of cranial, ophthalmic, nasal, upper lip, and palatal deformities. Reconstruction in these patients requires complex craniofacial efforts. A 19-year-old woman with frontonasal dysplasia was treated at our institution where she had undergone multiple prior reconstructive surgeries including facial bipartition and cantilevered calvarial bone graft for nasal reconstruction. ⋯ Its use also avoids further donor site morbidity. We suggest acellular dermal matrix as a graft material in revision rhinoplasties for cases of acquired nasal contour deformity and threatened bone graft extrusion. This is the first report known to the authors using acellular dermal matrix during staged nasal reconstruction in a patient experiencing frontonasal dysplasia.

This study evaluates 22 patients with retained foreign bodies in the maxillofacial region that were all caused by penetrating missile injuries. Surgical intervention for the retrieval of the foreign bodies was carried out in 20 patients through the existing wounds and through separate incisions; all patients were followed up for a minimum of 2 months during which all the complications were registered and managed. ⋯ All patients developed complications that were categorized in this study into those that result from the injury itself and those that occur because of the retrieval procedure, the latter category being mostly easily managed. In general, all foreign bodies in the maxillofacial region should be removed; the surgeon involved should weigh the benefits and the perils of the removal, and the patient should be well informed about the possibility of the failure of removal of the foreign body.

Comparative Study
Assessment of the adequacy of closed reduction in fractures of the zygomatic arch using "C"-arm image intensifier.
Major problems in closed reduction of isolated, minimally displaced, and depressed zygomatic arch fractures are blind nature of the technique, reliability on digital palpation, reduction click, and step deformity between fragments. The purpose of this study was to objectively confirm the adequacy of closed reduction intraoperatively and the usefulness of the "C"-arm image intensifier. A total of 12 patients with 1- to 8-day-old unilateral isolated and depressed zygomatic arch fracture underwent closed reduction under "C"-arm image intensifier. ⋯ In this patient, additional stabilization was provided. The "C"-arm image intensifier shows some poorly reduced or unstable isolated depressed zygomatic arch fractures that remain unidentified even after careful palpation. Thus, it plays a recognizable role to avoid the trouble of second intervention.
