Cutaneous sensibility impairment after mandibular sagittal split osteotomy: a prospective clinical study of the spontaneous recovery.
The aim of this prospective study was to objectively evaluate the inferior alveolar nerve (IAN) sensory disturbances in patients who underwent sagittal split ramus osteotomy (SSRO) and its spontaneous recovery and to define the incidence of sensibility loss, time, and area at which the recovery occurs. ⋯ The SSRO presents the disadvantage of temporary paresthesia; however, spontaneous nerve function recovery does occur. The Semmes-Weinstein test is a reliable, inexpensive, and easy-to-apply tool, which can be used for clinical evaluation on a daily basis at offices and hospitals.

A comparison of motorcycle and bicycle accidents in oral and maxillofacial trauma.
The aim of this study was to present a large series of motorcycle- and bicycle-related traumas to the face in an attempt to identify the injury pattern in motorcyclists and bicyclists. ⋯ The high-impact collisions typically observed in motorcycle accidents is directly related to larger percentages of soft tissue lacerations and facial fractures. The low-impact trauma that is observed in bicycle accidents is more commonly associated with soft tissue abrasion, hematoma, and dentoalveolar fractures. This stresses the need for compulsory legislation for helmet use with face-guards for cyclists and motorcyclists. It is important to take measures to alert the public regarding the severity of injuries likely to occur in bicycle- and motorcycle-related accidents and ways to prevent them.

Increased β-endorphin levels and generalized decreased pain thresholds in patients with limited jaw opening and movement-evoked pain from the temporomandibular joint.
Patients with limited jaw opening and movement-evoked pain from the temporomandibular joint have moderate to severe pain that may be relieved by surgery. The purpose of this study was to investigate if the preoperative state is associated with alterations in plasma β-endorphin (βE) levels and pain thresholds. ⋯ This study showed that patients with limited jaw opening and movement-evoked pain from the temporomandibular joint had significantly higher plasma βE levels and lower pressure pain thresholds in the orofacial area and at remote sites compared with pain-free, healthy, age-matched controls. An increased level of βE seems insufficient to inhibit pain and central sensitization. Further studies are warranted to elucidate the relation between βE and pain thresholds secondary to stress, inflammation, and discectomy.

Risk factors affecting hemorrhage after tooth extraction in patients undergoing continuous infusion with unfractionated heparin.
To identify the risk factors affecting the incidence of postoperative hemorrhage (POH) associated with tooth extraction in patients undergoing continuous infusion with unfractionated heparin. ⋯ The results of the present study suggest that POH in tooth extraction occurs often in patients with an APTT of 57 seconds or greater when the continuous heparin infusion cannot be stopped.

Subjective outcomes of maxillomandibular advancement surgery for treatment of obstructive sleep apnea syndrome.
To evaluate subjective outcomes and use of continuous positive airway pressure (CPAP) after maxillomandibular advancement surgery for treatment of obstructive sleep apnea syndrome (OSAS). ⋯ Maxillomandibular advancement surgery for treatment of OSAS is very effective at improving excessive daytime sleepiness, snoring, and witnessed apneas. Most patients in this study were able to discontinue the use of CPAP after surgery. Overall, patients reported the treatment to be worthwhile and would recommend it to others.
