Microsurgical repair of the peripheral trigeminal nerve after mandibular sagittal split ramus osteotomy.
Injuries to the inferior alveolar nerve (IAN) and lingual nerves (LNs) have long been known complications of the mandibular sagittal split ramus osteotomy (SSRO). Most postoperative paresthesias resolve without treatment. However, microsurgical exploration of the nerve may be indicated in cases of significant persistent sensory dysfunction associated with observed or suspected localized IAN or LN injury. We report the demographics and outcome of microsurgical exploration and repair of peripheral branches of the trigeminal nerve injured because of the SSRO. ⋯ Microsurgical repair of the IAN or LN injured during the SSRO can be considered in patients with persistent, unacceptable sensory dysfunction in the distribution of the involved nerve. Modifications of surgical technique may be helpful in reducing the incidence of such injuries. Based on our experience, an algorithm for evaluation and treatment is presented.

Review Meta AnalysisLaryngeal mask airways have a lower risk of airway complications compared with endotracheal intubation: a systematic review.
The purpose of the present study was to determine whether, in patients undergoing general anesthesia, those provided with a laryngeal mask airway (LMA) have a lower risk of airway-related complications than those undergoing endotracheal intubation. ⋯ For the patients receiving general anesthesia, the use of the LMA resulted in a statistically and clinically significant lower incidence of laryngospasm during emergence, postoperative hoarse voice, and coughing than when using an ETT. The risk of aspiration could not be determined because only 1 study reported a single case of aspiration, which was in the group using the ETT.

Assessment of trigeminal nerve functions by quantitative sensory testing in patients and healthy volunteers.
Orofacial sensory dysfunction plays an important role in oral and maxillofacial surgery. Quantitative sensory testing (QST) is a psychophysical approach to evaluate thermal and mechanical somatosensation. ⋯ Age, gender, and anatomic region affect various QST parameters. QST might be useful in the diagnosis of inferior alveolar nerve disorders in patients. In dentistry, the monitoring of afferent nerve fiber functions by QST might support decisions on further interventions.

The fibula osteomyocutaneous flap for mandible reconstruction: a 15-year experience.
This report documents our experience over the previous 15 years using free vascularized fibular flaps for comprehensive reconstruction of large defects in the mandible, after combined resections of aggressive, malignant odontogenic tumors or for post-traumatic defects. ⋯ In our opinion, the free fibula osteocutaneous flap is the most versatile and reliable option for microsurgical reconstruction of large mandibular defects. It provides a large quantity of bone, which is easily shaped to passively adapt to the remaining mandible. The bone height is suitable for an implant-based prosthetic restoration. Preoperative mapping of the cutaneous perforators of the skin paddle improves the versatility of the flap design and decreases the morbidity at the donor site. In selected cases, other options (iliac crest or scapular free flap) may also be considered.
