As cutaneous nerves cover all areas of the skin, and any surgery which requires incisions may inadvertently cause injury or scarring, now entrapping a cutaneous nerve. [ 15 ] A common tradeoff when electing to a neurectomy is that numbness along the nerve distribution is expected.
Smile surgery or smile reconstruction is a surgical procedure that restores the smile for people with facial nerve paralysis. Facial nerve paralysis is a relatively common condition with a yearly incidence of 0.25% leading to function loss of the mimic muscles. [1]
Tumour of facial nerve like schwannomas and perineuromas. Other tumours that can compress facial nerve along its course like congenital cholesteatomas, hemangiomas, acoustic neuromas, parotid gland neoplasms, or metastases of other tumors. Other causes like viral, bacterial or fungal infections like chicken pox, streptococcal infection or ...
Nerve decompressions are still a relatively new surgery, however a picture emerges from looking at the outcomes of some of the most studied nerve decompressions: carpal tunnel release, sciatic nerve decompression, and migraine surgery. Even within these commonly performed surgeries, the measurement of outcomes is not always standardized.
The surgeon takes consideration to not distort the anatomy of the ear. A flap is made on the surface of the parotid gland to help expose the gland and tissue to be removed. Veins and nerve branches are identified and if necessary, specific nerves are dissected. Facial nerve monitoring has been found to reduce nerve associated morbidities. [8]
The facial nerve, which innervates the muscles of the face, is preserved in a higher percentage of cases than with other approaches. Prior to the translabyrinthine approach, in the early 1960s acoustic neuromas were treated utilizing a suboccipital approach without the aid of an operating microscope.
Microvascular decompression (MVD), also known as the Jannetta procedure, [1] is a neurosurgical procedure used to treat trigeminal neuralgia (along with other cranial nerve neuralgias), a pain syndrome characterized by severe episodes of intense facial pain, and hemifacial spasm.
Thus the facial artery can be used as an important landmark in locating the marginal mandibular nerve during surgical procedures. [2] Damage can cause paralysis of the three muscles it supplies, which can cause an asymmetrical smile due to lack of contraction of the depressor labii inferioris muscle . [ 3 ]
