Acute, Isolated Cranial Nerve III Palsy

The oculomotor nerve (cranial nerve III) innervates multiple muscles. It innervates superior rectus, inferior rectus, medial rectus, inferior oblique, levator palpebrae, sphincter pupillae, and ciliary muscles. If this nerve is damaged, malfunctioning of those muscles arises. Inferolateral displacement of the eyeball results from extraocular muscles denervation (superior rectus, inferior rectus, medial rectus, inferior oblique). Complete ptosis results from levator palpebrae denervation. Mydriasis results from sphincter pupillae and ciliary muscles denervation, which are parasympathetically regulated. The signs and symptoms always occur ipsilaterally.

Strides Made in Recruiting Women to Neurosurgery – More than 20 Percent of Neurosurgical Residents Now Female

In 2007, the American Association of Neurological Surgeons (AANS) recognized the need to take bold steps to recruit and retain more women in neurosurgery and requested that Women in Neurosurgery (WINS) author a white paper. “The article, which was published in the September 2008 issue of Journal of Neurosurgery, has clearly made an impact on the field with the number of new female neurosurgical residents nearly doubling from just two years ago,” said Deborah Benzil, MD, lead author of that article.
