Delayed signs and symptoms after oropharyngeal trauma in a child.

Injury to the oropharynx can be potentially life threatening. Innocent-looking injuries of the oropharynx may result in intravascular thrombosis of the internal carotid artery. The symptoms often appear some time after the initial injury. We present a case in which an apparently minor injury of the oropharynx developed into a life-threatening thrombus stretching from the internal carotid to the brain. Our patient underwent endarterectomy and thrombectomy. The case is presented with a review of the literature.

Large myelinated nerve fiber hypersensitivity in oral malignancy.

OBJECTIVES: The purpose of this study was to assess the sensory function of trigeminal nerve A-beta fibers in suspected soft tissue oral malignancies. STUDY DESIGN: Twenty-three patients referred for the evaluation of an oral lesion suspected of malignancy were included in the study. All lesions were classified as in, near, or out of the nerve territory containing the lesion. Within these subgroups we assessed the sensitivity of A-beta primary afferents to weak electrical currents applied bilaterally to regions innervated by 3 peripheral branches of the trigeminal nerve. The ratio of electrical detection thresholds from the affected and the unaffected side was calculated. Electrical detection threshold ratios were contrasted with the results of physical examination, radiographic imaging, and biopsy. RESULTS: For dermatomes containing the lesions, ratios were lower than 0.8 in 12 patients. Biopsy showed that the lesions in 10 of these 12 patients were malignant. No malignancy was found in the remaining 11 patients. CONCLUSIONS: A-beta primary afferent hypersensitivity is observed to occur in nerves exposed to soft tissue oral malignancy.

Reconstruction of the mandible by fibula free flap.

BACKGROUND: The most frequent cause of defect in the mandible is tumor-related surgery. Larger defects or anterior arch defects cause severe morbidity due to disturbances in function and esthetics. OBJECTIVES: To assess the outcome of free tissue transfer for mandible reconstruction. METHODS: Since 1998 we operated on 11 patients with mandible defects using the fibula flap as the reconstruction method. We performed immediate reconstruction in eight patients after ablative surgery, and late reconstruction due to radiation-induced complications in three. RESULTS: All patients achieved good functional and esthetic outcome. During the follow-up period two patients died of their malignant disease and one patient died from a non-related cause. Although two patients underwent reoperation in the first 3 months after their primary operation due to fixation failure, there were no other major complications. CONCLUSIONS: According to the literature and our limited experience, the fibula flap is a safe and reliable option for mandible reconstruction.
