1/10. Single osteotomized iliac crest free flap in anterior mandible reconstruction.While the iliac crest flap provides a natural contour for the lateral segment of the mandible, for the anterior segment en bloc, the use of the iliac graft, even harvested in a V shape, fails to yield a three-dimensional natural-shaped reconstruction. In this report, we present our experience with reconstruction of the anterior segment of the mandible using a single osteotomized free iliac crest flap in 5 patients. The study comprised 4 male patients and 1 female patient, their ages ranging between 34-82 years. In all patients, composite iliac osteomusculocutaneous flaps were harvested based on the deep circumflex iliac artery in the standard manner, and the bony segment of the flap was divided into two segments, performing a single osteotomy. The fixation of bone segments was performed in new positions, sliding the segments in different planes to provide the original shape of the resected mandible segment, and in a manner appropriate to the defect. The overall flap success rate was 100%. In no cases were wound infections or hematomas observed. x-rays showed bone healing without resorption. In conclusion, the use of a single osteotomy for an iliac crest flap in the reconstruction of the anterior segment of the mandible is a simple and safe procedure, and provides a natural and acceptable jaw appearance. The risk of devascularization is quite low when compared with the multiple osteotomy procedure, and it does not need to be fixed with complex devices such as reconstruction plates or external fixators.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
2/10. Repair of skin covering osteoradionecrosis of the mandible with the fasciocutaneous supraclavicular artery island flap: case report.INTRODUCTION: osteoradionecrosis of the mandible is a serious complication following radiotherapy for head and neck cancer. Reconstructive procedures in the head and neck region use a wide range of flaps for defect closure. The methods range from local, mostly myocutaneous flaps and skin grafts to free microsurgical flaps to ensure a satisfactory functional and aesthetic result. Moreover, the donor site defect needs to be closed, with as little as possible functional or aesthetic impairment. PATIENT AND METHOD: A 60-year-old male is presented with a history of squamous cell carcinoma of the left lower lip and chin area in whom the tumour was resected and treated by adjuvant radiotherapy. The follow-up was complicated by chronic inflammation of the left mandibular body as a sequel of radiotherapy; it resulted with partial bone destruction, and soft tissue dehiscence. He was admitted for repair and treatment of the infected mandibular osteoradionecrosis. A supraclavicular artery island flap was used to close the mandibular soft tissue defect. CONCLUSION: The shoulder provides a relatively good skin texture and match to provide cover and lining for defects in the lower part of the face, in combination with minor donor site morbidity.- - - - - - - - - - ranking = 0.625keywords = mandible (Clic here for more details about this article) |
3/10. An unusual oral presentation of a metastatic basal cell carcinoma.A case report of a metastasising basal cell carcinoma is presented. The primary lesion was situated on the right upper lip with metastasis to soft tissue on the buccal aspect of the right molar region of the mandible. The literature regarding this unusual occurrence is reviewed.- - - - - - - - - - ranking = 0.125keywords = mandible (Clic here for more details about this article) |
4/10. Microcystic adnexal carcinoma with mandibular invasion and bone marrow replacement.A 51-year-old man with microcystic adnexal carcinoma of the face is reported. In addition to extensive soft tissue invasion by the cancer, there was direct bone invasion into the marrow of the mandible as well as perineural spread along the mental and inferior alveolar nerves. This represents the first case of microcystic adnexal carcinoma with documented bone invasion. Recognition of the aggressive nature of this cancer with potential for invasion into the skull is important for proper evaluation and treatment.- - - - - - - - - - ranking = 0.125keywords = mandible (Clic here for more details about this article) |

The use of the compound radial forearm flap in oro-mandibular reconstruction.The radial forearm flap may be used as an osteo-cutaneous unit to replace the bone of the mandible and the overlying mucosa. The technique and its complications are described and illustrated by three case reports.- - - - - - - - - - ranking = 0.125keywords = mandible (Clic here for more details about this article) |
7/10. Lower lip carcinoma. Infiltration of the mandible along the mental nerve.In general, carcinoma of the lower lip has a good prognosis after radical surgery. In rare cases, however, recurrences may be seen because of spread of the tumour along the mental nerve into the mandible. The earliest symptom of this is pain in the mandible and radiological evidence of widening of the mental foramen. Large resections and reconstructive procedures will be necessary. Three cases are presented.- - - - - - - - - - ranking = 0.75keywords = mandible (Clic here for more details about this article) |
8/10. The use of transarterial microembolization in the management of hemangiomas of the perioral region.The management of oral and perioral hemangiomas depends on several clinical factors. Surgery of these benign lesions can at times be disfiguring, especially when the lips, muscles, or the maxilla and mandible are involved. In addition, by the very nature of these lesions, surgical treatment may be associated with excessive intra- and perioperative blood loss. A series of five patients who had hemangiomas in the perioral region and who were initially treated with transarterial microembolization, preoperatively in two cases and as the only treatment in three cases, is presented. The technique of microembolization is described and recommendations for its use are given.- - - - - - - - - - ranking = 0.125keywords = mandible (Clic here for more details about this article) |
9/10. Unusual manifestations of multiple cranial nerve palsies and mandibular metastasis in a patient with squamous cell carcinoma of the lip.A 70-year-old man who had squamous cell carcinoma of the lip later presented with right mental neuropathy, ipsilateral progressive involvement of all three divisions of the 5th, the 7th and 8th cranial nerves, and complete ophthalmoplegia. biopsy proven metastasis to the mandible was demonstrated. Although repeated studies of CT scan of the head and cerebral angiography were negative, CSF examination revealed positive cytology, elevated protein and low sugar content. Although vascular dissemination from the primary lip lesion to the mandible and brain stem cannot be ruled out, extension through perineurial space via the 5th cranial nerve have been speculated. This case demonstrates two unusual features of squamous cell carcinoma of the lip, namely metastasis to the mandible and meningeal spread with multiple cranial neuropathies.- - - - - - - - - - ranking = 0.375keywords = mandible (Clic here for more details about this article) |
10/10. Perineural invasion by carcinoma of the lower lip.Extension of lip cancer to the mental nerve and perineural spread was found in four patients. The main complaint in all cases was sensory disturbance which preceded the diagnosis of recurrence by perineural spread as well as widening of the mandibular canal. In one patient, two cranial nerves, the trigeminal and the facial were involved and one patient had bilateral neural involvement. Three patients died within 1 year of the diagnosis of perineural spread. Prevention includes the separate examination of specimens at the resection line near the mental nerve, and follow-up by examination of the lower vestible, X-ray of the mandible and monitoring of sensory disturbance.- - - - - - - - - - ranking = 0.125keywords = mandible (Clic here for more details about this article) |
