Simultaneous maxillo-mandibular distraction osteogenesis in hemifacial microsomia: a new technique using two distractors.

BACKGROUND: The goal of this study was to prospectively evaluate the use of two distractors for a simultaneous maxillo-mandibular distraction osteogenesis without the use of intermaxillary fixation in the restorative treatment of hemifacial microsomia. METHODS: The authors analyzed the clinical and radiological data of five patients with type I hemifacial microsomia (one patient), type IIa hemifacial microsomia (two patients), and Goldenhar syndrome (two patients). Follow-up examinations were performed at 1, 3, 6, and 12 months. RESULTS: All the patients had satisfactory correction of the facial asymmetry without complications. Complete horizontalization of the occlusal plane was achieved in three patients, whereas a cant of 2 degrees persisted in two patients. None of the children in this study were noncompliant with the prescribed duration of the active distraction period, nor did they experience technical problems with the two devices. CONCLUSIONS: Simultaneous maxillo-mandibular distraction osteogenesis resulted in a high rate of success in correcting facial asymmetry as well as occlusal plane cant. It offered good aesthetic satisfaction.

Congenital intracranial frontotemporal dermoid cyst presenting as a cutaneous fistula.

BACKGROUND: Intracranial extension and a cutaneous sinus tract are rarely seen with craniofacial dermoid cysts, with few cases reported in the literature. METHODS: We report a case of a 1-year-old girl who was initially seen with a cutaneous fistula of the frontotemporal region, which revealed an intracranial dermoid cyst. RESULTS: The patient underwent a right lateral orbitotomy by a bicoronal approach. The cyst was seated within the lateral orbital wall, with intracranial extension through the temporal and sphenoidal bones to the dura of the temporal lobe. Histopathologic analysis confirmed the diagnosis of a dermoid cyst. CONCLUSIONS: Craniofacial dermoid cysts may be associated with a cutaneous sinus tract and/or intracranial extension. Failure to recognize and promptly treat these lesions may lead to a progressive skeletal distortion and/or recurrent infection with a potential for meningitis or cerebral abscess. Therefore, detailed CT and MRI scans are mandatory before surgical treatment of any cutaneous fistula in the head and neck region.

Enteric bacteria mandibular osteomyelitis.

Osteomyelitis of the mandible is a relatively rare inflammatory disease that usually stems from the odontogenic polymicrobial flora of the oral cavity. We are reporting 2 unusual cases of mandibular osteomyelitis resulting from enteric bacteria infection. In one patient, abundant clinical evidence suggested a diagnosis of a chronic factitious disease, whereas in the second patient no obvious etiology was found.

Successful treatment of a postpolio tinnitus with type a botulinum toxin.

OBJECTIVES/HYPOTHESIS: Objective tinnitus is a symptom often observed in patients with chronic hyperactivity of masticatory muscles. METHODS: We report here the unusual case of a 63-year-old woman who developed a distressing tinnitus related to contractions of reinnervated masticatory muscles. This reinnervation process was caused by a postpolio syndrome that gave rise to an acoustic resonance phenomenon transmitted to the middle ear as an audible sound. RESULTS: The tinnitus was successfully treated with electromyography-guided intramuscular injections of type A botulinum toxin. CONCLUSION: The intramuscular injection of botulinum toxin was found to be effective in relieving severe and disabling postpolio tinnitus.

Upper lip swelling caused by a large dentigerous cyst.

Swelling of the upper lip can result from various diseases such as salivary tumors, infectious and inflammatory diseases and cysts. Among the latter, dentigerous cysts, typically involving unerupted teeth, are sometimes associated with supernumerary teeth in the maxillary anterior incisors region called the mesiodens. We report an unusual case of a large dentigerous cyst associated with an impacted mesiodens in a 42-year-old male who presented with a slow-growing swelling in the upper lip.

Successful inferior alveolar nerve decompression for dysesthesia following endodontic treatment: report of 4 cases treated by mandibular sagittal osteotomy.

Endodontic overfilling involving the mandibular canal may cause an injury of the inferior alveolar nerve (IAN) resulting in disabling sensory disturbances such as pain, dysesthesia, paresthesia, hypoesthesia, or anesthesia. Two fundamental mechanisms are responsible for the injury: the chemical neurotoxicity and the mechanical compression caused by the extruded material. Although spontaneous resorption has been described for some materials, early surgical exploration with removal of the material and decompression of the IAN should be performed, irrespective of the material used, given that the importance of nerve damage increases with the duration of the injury. We report 4 cases of disabling dysesthesia and paresthesia following endodontic treatment of lower molars in which sagittal osteotomy was used to remove the endodontic paste and to perform nerve decompression. All the patients experienced immediate relief of dysesthesia and paresthesia.

Treatment of midfacial defects using prostheses supported by ITI dental implants.

The purpose of this study was to evaluate retrospectively the use of ITI dental implants used for anchoring facial prostheses in the restorative treatment of midface defects. The authors analyzed the clinical data of 26 patients with orbital defects (n = 11), orbitonasal defects (n = 4), orbitonasomaxillary defects (n = 3), and nasal defects (n = 8). Data included age, sex, primary disease, implant position, implant length, implant failure, prosthetic attachment, radiation therapy, and peri-implant skin reactions. Follow-up was at 1, 3, 6, and 12 months and then on a yearly basis. The authors noted the status of healing and complications, if any. In total, 62 implants were placed as follows: 27 (43.5 percent) for orbital prostheses, 12 (19.4 percent) for orbitonasal prostheses, 14 (22.6 percent) for orbitonasomaxillary prostheses, and nine (14.5 percent) for nasal prostheses. Thirty-eight implants (61.3 percent) were placed in previously irradiated areas in 18 patients (69.2 percent). Mild skin reactions together with mild accumulation of sebaceous crusting around implants were recorded in 14.2 percent of the skin observations. No patient experienced severe inflammation requiring administration of systemic antibiotics or surgical revision. Implant success was 100 percent in both irradiated and nonirradiated patients. In conclusion, ITI dental implants result in a high rate of success in retaining midface prostheses and offer good stability and aesthetic satisfaction.

Intraoral venous malformation presenting with multiple phleboliths.

Venous malformations are the most common of all vascular anomalies. Phleboliths are described as characteristic of such malformations; furthermore, when they are encountered in the major salivary glands, they must be differentiated from salivary calculi. We report a case of an intraoral venous malformation in the left retromolar area with multiple phleboliths.

Treatment of severe mandibular fractures using AO reconstruction plates.

PURPOSE: The goal of this study was to retrospectively evaluate the use of 2.4-mm AO titanium reconstruction plates for mandibular fractures. PATIENTS AND METHODS: We analyzed the clinical and radiologic data of 63 patients with 63 single fractures (53 comminuted, 5 dislocated, and 5 with bone loss) and 2 patients with double fractures. Fracture location was symphysis in 37 patients (56.9%), body in 13 (20%), and angle in 15 (23.1%). We recorded the mechanism of injury, time between injury and surgery, gender and age, temporary maxillomandibular fixation (MMF) and its duration, and surgical approach. Follow-up examinations were performed at 1, 3, 6, and 12 months, at which time we noted the status of healing and any complications. RESULTS: Fifty patients (77%) had a successful treatment outcome without complications; 13 patients (20%) developed minor complications; and 2 patients (3%) developed nonunion with infection requiring hardware removal and reosteosynthesis with bone graft. CONCLUSIONS: We found that 2.4-mm AO titanium reconstruction plates can be used to treat severe mandibular fractures with a low rate of major complications (3%) and a high success rate.
