Another possible complication of an inferior alveolar nerve block occurs when the needle is placed too deep, passing through the pterygomandibular space and into the parotid gland behind. Branches of the facial nerve (which gives the motor supply to the muscles of facial expression ) run through the substance of the parotid gland and so this is ...
Neurectomy can be an alternative to a nerve decompression for nerve entrapment, such as when the nerves have no motor function and numbness along the dermatome is acceptable. A neurectomy is not a mutually exclusive option to a decompression as a neurectomy can also be used after a failed decompression.
The chorda tympani nerve (from the facial nerve via the submandibular ganglion) is secretomotor and provides parasympathetic supply to the sublingual glands. The path of the nerve is as follows: junction between pons and medulla, through internal acoustic meatus and facial canal to chorda tympani, through middle ear cavity, out petrotympanic fissure to join the lingual nerve, travels with ...
The medial pterygoid nerve is a main trunk from the mandibular nerve, before the division of the trigeminal nerve - this is unlike the lateral pterygoid muscle, and all other muscles of mastication which are supplied by the anterior division of the mandibular nerve.
An injury to this nerve during a surgical procedure can distort the expression of the smile as well as other facial expressions. The marginal mandibular branch of the facial nerve is found superficial to the facial artery and (anterior) facial vein.
The lingual nerve supplies general somatic afferent (i.e. general sensory) innervation to the mucous membrane of the anterior two-thirds of the tongue (i.e. body of tongue) (whereas the posterior one-third (i.e. root of tongue) is innervated via the glossopharyngeal nerve (CN IX) [citation needed]), the floor of the oral cavity, and the mandibular/inferior lingual gingiva.
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] The facial nerve gives off several branches in the face.
Buccal nerve block (long buccal nerve block) is indicated for procedures involving the mucosa adjacent to the posterior molar teeth, such as the placement of a rubber dam clamp. The injection site is distal and buccal to the third molar, with the needle penetrating 1-2mm as the nerve lies directly below the mucosa. [5]
