Intraoperative electrophysiologic monitoring can diminish the risk of neurologic injury by enabling the detection of injury at a time when it can be reversed or minimized. This report describes a 14-year-old girl with a Chiari's malformation type I and syringomyelia who underwent a suboccipital decompression and dural patch grafting with concurrent somatosensory evoked potentials. When the patient was turned into the prone position and the neck was flexed, the left-sided somatosensory evoked potential deteriorated. ⋯ Postoperatively, the patient had decreased proprioception of her left arm, which completely resolved at 2-week follow-up. This single case report does not establish the need for routine somatosensory evoked potential monitoring. Nevertheless, deterioration of the potential in this case led directly to a change in the surgical positioning, which may have significantly reduced the chances of a permanent neurologic injury.

The sphenoid sinus is often referred to as the "neglected sinus." Isolated sphenoid sinusitis is a rare disease with potentially devastating complications. It occurs at an incidence of about 2.7% of all sinus infections. Although headache is the most common presenting symptom, there is no typical headache pattern. ⋯ The sensory innervation of the sphenoid sinus is derived from the ophthalmic and maxillary branches of the trigeminal nerve, which may explain the pathophysiology of the headache, similar to the trigeminovascular pain theory of migraine. There are few reports on sphenoid sinusitis and headache; however, modern neuroimaging has made this probably under-recognized disorder easier to diagnose and treat. Although the diagnosis can be difficult to differentiate from migraine headache, early and appropriate treatment usually results in an excellent outcome without morbidity.

Seizures are commonly associated with hypoxic-ischemic encephalopathy. Although the majority of cases are controlled with first- or second-line therapy, others develop pervasive seizures, requiring multiple anticonvulsants. ⋯ The remaining 30 infants received phenytoin as a second-line anticonvulsant, and seizures stopped in 10 cases. The 20 infants with ongoing pervasive seizures were treated with intravenous paraldehyde.
