Cranio-maxillofacial trauma: a 10 year review of 9,543 cases with 21,067 injuries.
Cranio-maxillofacial trauma management requires pertinent documentation. Using a large computerized database, injury surveillance and research data describe the whole spectrum of injuries. The goal of this study was to assess the effect of the five main causes of accidents resulting in facial injury on the severity of cranio-maxillofacial trauma. ⋯ This study differentiated between injury mechanisms in cranio-maxillofacial trauma. The specially trained surgeons treating cranio-maxillofacial trauma are the primary source of information for the public and legislators on implementing preventive measures for high-risk activities. In facial trauma, older persons are prone to bone fractures (increase of 4.4%/year of age) and soft tissue injuries (increase of 2%/year of age) while younger persons are more susceptible to dentoalveolar trauma (decrease of 4.5%/year of age).

Neurosensory alterations of the inferior alveolar and mental nerve after genioplasty alone or associated with sagittal osteotomy of the mandibular ramus.
The purpose of our protocol is to study neurosensory disturbances following genioplasty, sagittal split mandibular osteotomy, or both procedures in combination. Many authors assessed the incidence and degree of neurosensory disturbances of the inferior alveolar nerve following orthognathic surgery but often results are difficult to interpret and compare due to a lack of standardization of methods. ⋯ The combination of genioplasty and sagittal split osteotomy seems to be more detrimental for the lip sensibility than genioplasty or sagittal split alone. Thermal sensation is less affected than tactile sensation, location and two point discrimination tests (static and dynamic). Despite that, sensory deficit was never considered as disabling by the patients subjectively.

It has been reported that streptomycin can have anti-neuralgic effects. However, the mode of action is unknown. This article was intended to investigate eventual neurolytic effects of streptomycin on peripheral nerves when applied topically. ⋯ Streptomycin can cause peripheral nerve damage when injected perineurally. These morphological changes may be responsible for anti-neuralgic effects of streptomycin.

Case ReportsTrigeminocardiac reflex: a unique case of recurrent asystole during bilateral trigeminal sensory root rhizotomy.
The trigeminocardiac reflex is the sudden-onset of dysrhythmia and hypotension during manipulation of any of the branches of the trigeminal nerve. The trigeminal nerve and cardioinhibitory vagus nerve constitute the afferent and efferent pathways in the reflex arc. The trigeminocardiac reflex has been reported to occur during craniofacial surgery, balloon-compression rhizolysis of the trigeminal ganglion, and tumour resection in the cerebellopontine angle. ⋯ Sectioning of the intracranial dorsal sensory root of the trigeminal nerve provides clear evidence of the central role of the trigeminal nerve as the afferent pathway of the trigeminocardiac reflex arc.
