Microstructural Change and Cognitive Alteration in Maxillofacial Trauma and Mild Traumatic Brain Injury: A Diffusion Tensor Imaging Study.
The aim of the present study was to establish the incidence of maxillofacial (MF) injury accompanying mild traumatic brain injury (mTBI) and the associated neurocognitive deficits and white matter changes. ⋯ The presence of MF injury without any intracranial traumatic lesions in patients with mTBI increases the risk of short- and long-term neurocognitive derangement compared with patients with mTBI, MF injury, and intracranial traumatic lesions.

Pharyngeal Flap Is Effective Treatment for Post Maxillary Advancement Velopharyngeal Insufficiency in Patients With Repaired Cleft Lip and Palate.
Patients with repaired cleft lip and cleft palate (CL/P) can develop velopharyngeal insufficiency (VPI) after Le Fort I maxillary advancement. The aim of this study was to evaluate speech outcomes in patients who required a pharyngeal flap after Le Fort I maxillary advancement. ⋯ The superiorly based pharyngeal flap is highly successful in correcting VPI after Le Fort I maxillary advancement in patients with repaired CL/P.

Case ReportsThree Synchronous Atypical Metastases of Clear Cell Renal Carcinoma to the Maxillary Gingiva, Scalp and the Distal Phalanx of the Fifth Digit: A Case Report.
Oral cavity metastasis of malignant tumors is extremely rare and accounts for only 1% of all malignant oral tumors. Renal cell carcinoma (RCC) can metastasize to any part of the body, with a 15% risk of metastasis to the head and neck region when the disease is disseminated and a 1% risk when it is not. RCC also is the third most common infraclavicular neoplasm that metastasizes to the oral cavity, after lung carcinoma in men and breast carcinoma in women. ⋯ Clinical findings, diagnosis, pathology, and treatment of these lesions are discussed. Metastasis of RCC should always be included in the differential diagnosis when a new oral and maxillofacial lesion appears in a patient with a history of RCC because the metastatic lesions can often present in a broad spectrum of forms. The rapid growth of these lesions should alert clinicians to avoid any delays in biopsy examination and subsequent treatment, which is usually palliative, because prognosis is usually poor.
