Submental endotracheal intubation in concurrent orthognathic surgery: a technical note.
Achieving the necessary occlusion for orthognathic surgery is not possible with conventional oral intubation since the tube interferes with the occluding teeth. Sometimes nasotracheal intubation is impossible due to developmental malformations requiring repair. Also, the oral or nasotracheal tube may interfere with the operation or may be damaged during the procedure. In 1986, Hernandez Altemir described a method of submental endotracheal intubation. His intentions were to avoid tracheostomy in maxillofacial trauma cases where short-term intermaxillary fixation was required. ⋯ The technique is easy to use, rapid and free of complications compared to 'alternative' intubation methods (tracheostomy, retromolar location of tube, etc.). Submental scarring is acceptable. It is recommended for orthognathic procedures in selected cases.

Review Case ReportsDermoid cyst of the tongue: an association of dermoid cyst with bronchogenic epithelium.
A congenital dermoid together with a bronchogenic cyst of the tongue is extremely rare. The diagnosis made in this case of a 1-year-old boy was "teratoid cyst of the tongue". A surgical exploration was performed under general anaesthesia via a midline sagittal glossotomy. ⋯ Others were composed of cylindrical, ciliated epithelial cells of respiratory type. This is the third reported case in the world literature. All cases were reviewed and compared with this case.

Free flap monitoring using simultaneous non-invasive laser Doppler flowmetry and tissue spectrophotometry.
Early identification of flap failure is an indispensable prerequisite for flap salvage. Although many methods of free flap monitoring are available, there is still no single reliable non-invasive technique for early recognition of flap failure and for differentiation between arterial occlusion and venous congestion. The aim of this study was to investigate the benefits of the tissue oxygen analysis system O(2)C for monitoring patients undergoing maxillofacial reconstruction with fasciocutaneous radial forearm flaps. ⋯ For the first time this new device allows reliable prediction of venous congestion by an increase of haemoglobin-concentration, and of arterial occlusion by a decrease in blood flow parameters and oxygen saturation. It can thus differentiate the mechanisms of flap failure before clinical assessment.

In-line (18)F-fluorodeoxyglucose positron emission tomography with computed tomography (PET/CT) in patients with carcinoma of the sinus/nasal area and orbit.
Contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI) are the standard imaging techniques to evaluate patients with carcinoma in the sinus/nasal area and orbit. The use of positron emission tomography (PET) with (18)F-fluorodeoxyglucose (FDG) in such patients is as yet less well established. ⋯ Whole body PET/CT adds clinically important information to CT or MRI, thus, influencing treatment.

Comparative Studyp53 mutations and human papillomavirus infection in oral squamous cell carcinomas: correlation with overall survival.
The study investigated the pattern of p53 gene mutations and human papillomavirus (HPV) infection concerning their relation to overall survival in patients with oral squamous cell carcinomas of the tongue and floor of the mouth. ⋯ The results stress once more the importance of HPV for the prognosis of survival of patients with squamous cell carcinoma of lower parts of the oral cavity. The presence of p53 mutations in HPV-infected tumours was associated with an even poorer prognosis for the patients.
