This practical, comprehensive and highly illustrated book will be invaluable to students and doctors of neurology and internal medicine in Africa. Facial nerve palsy can be distinguished from a central facial nerve lesion (eg, due to hemispheric stroke or tumor), which causes weakness primarily of the lower face, sparing the forehead muscle and allowing patients to wrinkle their forehead; also, patients with central lesions can usually furrow their brow and close their eyes tightly. They are also useful in out­comes research. Weakness of the orbicularis oculi muscle and resulting incomplete eye closure may be associated with corneal injury. The House-Brackmann system is commonly used by clinicians to assess the severity of facial nerve palsy (box).9 It is also used by clinicians to assess recovery of function at different time points.

At 1 month after the onset of Bell's palsy, 32.4% (n=12) of patientshad complete clinical recovery and at 2 months, 73.0% (n=27) had complete clinical recovery. The House–Brackmann facial nerve grading system (the HB-system) is widely used in the US and Europe as a method for evaluation of facial nerve function. Then differences in evaluation results of the two methods were compared. Causes of Facial Paralysis. Complete assessment of facial nerve palsy should address the chronicity, severity, and laterality of the palsy, and comment on whether the palsy is either primary or secondary, and if lesion is likely a proximal or distal lesion. I. This is a gross grading system that includes evaluation items relevant to the sequelae such as contracture, synkinesis and spasm.
