Sensory Restoration of the Facial Region.

Ann Plast Surg 2018 Dec 13. Epub 2018 Dec 13.

From the Department of Plastic Surgery, University of Tennessee Health Science Center, Memphis, TN.

Normal sensitivity of the face is very important for preserving its integrity and function as an efferent source of information for the brain. The trigeminal nerve, which is the largest cranial nerve, conducts most of facial sensory function through its 3 branches: the ophthalmic nerve (V1), the maxillary nerve (V2), and the mandibular nerve (V3). The trigeminal nerve may be damaged by a variety of etiologies including inflammatory disorders, brain tumor resection, trauma, iatrogenic injury, or congenital anomalies. Read More

Histone deacetylase inhibitors prevent persistent hypersensitivity in an orofacial neuropathic pain model.

Mol Pain 2018 Jan-Dec;14:1744806918796763

2 Department of Physiology, College of Medicine, University of Kentucky, Lexington, KY, USA.

Chronic orofacial pain is a significant health problem requiring identification of regulating processes. Involvement of epigenetic modifications that is reported for hindlimb neuropathic pain experimental models, however, is less well studied in cranial nerve pain models. Three independent observations reported here are the (1) epigenetic profile in mouse trigeminal ganglia (TG) after trigeminal inflammatory compression (TIC) nerve injury mouse model determined by gene expression microarray, (2) H3K9 acetylation pattern in TG by immunohistochemistry, and (3) efficacy of histone deacetylase (HDAC) inhibitors to attenuate development of hypersensitivity.
