Facial motor nucleus
Overall, free tissue transfer to the face can be considered a safe and efficient method for the restoration of facial muscle movement. Incise a strip of approximately 2cm and rotate it distally through a preformed subcutaneous tunnel down to the mesiolabial fold. Such patients not only have dysfunctions in the facial expression but also a difficulty in communication. Guhl, in American Trypanosomiasis Chagas Disease Second Edition , Assessment of regions affected by Chagas disease In the last 10 years, due to the successful interruption of the vectorial and transfusional transmission of infection by T. In the last 10 years, due to the successful interruption of the vectorial and transfusional transmission of infection by T. If the lesion is deeper e. Also look for asymmetries in spontaneous facial expressions and blinking.
Chapter 5: Facial sensations & movements
A recent transneuronal study in the rat demonstrates strong input from the mesencephalic reticular regions including the interstitial nucleus of Cajal InC and the superior colliculus. The abducens nerve is located near the internal carotid artery within the cavernous sinus. The facial motor nucleus receives a prominent 5-HT innervation, as demonstrated by fluorescence histochemistry Fuxe, and biochemical measures Palkovits et al. Both the abducens and facial nuclei are located in the pons, and the fasciculus of the facial nucleus arches around the abducens nucleus. The trochlear nucleus is near the oculomotor nucleus, and if it too is involved, the contralateral superior oblique muscle will be affected. Intracranial Involvement For the most part, the trochlear nerve follows the same path as the oculomotor nerve and is susceptible to the same injuries. Of these, an estimated 5.
Total paralysis No movement. Iatrogenic injury to the facial nerve most often is seen after cervicofacial rhytidectomies, surgery of the parotid gland, acoustic neuroma resection, or tumor resection at any point along the course of the facial nerve. This information is intended for medical education, and does not create any doctor-patient relationship, and should not be used as a substitute for professional diagnosis and treatment. Given that facial nerve palsy is a clinical diagnosis, and that the most common cause of facial nerve palsy is idiopathic, routine imaging, serology, or other testing is not necessary. Depending on the affected trunk and localization proximal or distal , various patterns of motor function loss can be seen and used for primary diagnosis of the lesion site.
