  2. House–Brackmann score - Wikipedia

    en.wikipedia.org/wiki/House–Brackmann_score

    The House–Brackmann score is a score to grade the degree of nerve damage in a facial nerve palsy. The measurement is determined by measuring the upwards (superior) movement of the mid-portion of the top of the eyebrow, and the outwards (lateral) movement of the angle of the mouth. Each reference point scores 1 point for each 0.25 cm movement ...

  3. Marginal mandibular branch of the facial nerve - Wikipedia

    en.wikipedia.org/wiki/Marginal_mandibular_branch...

    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 ]

  4. Facial nerve paralysis - Wikipedia

    en.wikipedia.org/wiki/Facial_nerve_paralysis

    Bell's palsy is the most common cause of acute facial nerve paralysis. [ 3 ] [ 4 ] There is no known cause of Bell's palsy, [ 5 ] [ 6 ] although it has been associated with herpes simplex infection. Bell's palsy may develop over several days, and may last several months, in the majority of cases recovering spontaneously.

  5. Mandibular nerve - Wikipedia

    en.wikipedia.org/wiki/Mandibular_nerve

    The mandibular nerve immediately passes between tensor veli palatini, which is medial, and lateral pterygoid, which is lateral, and gives off a meningeal branch (nervus spinosus) and the nerve to medial pterygoid from its medial side. The nerve then divides into a small anterior division and a large posterior division.

  6. Depressor anguli oris muscle - Wikipedia

    en.wikipedia.org/wiki/Depressor_anguli_oris_muscle

    Damage to the marginal mandibular branch of the facial nerve may cause paralysis of the depressor anguli oris muscle. [1] This may contribute to an asymmetrical smile. [1] This may be corrected by resecting (cutting and removing) the depressor labii inferioris muscle, which has a more significant impact on smiling. [1]

  7. Auriculotemporal nerve - Wikipedia

    en.wikipedia.org/wiki/Auriculotemporal_nerve

    The auriculotemporal nerve is a sensory branch of the mandibular nerve (CN V 3) that runs with the superficial temporal artery and vein, and provides sensory innervation to parts of the external ear, scalp, and temporomandibular joint. The nerve also conveys post-ganglionic parasympathetic fibres from the otic ganglion to the parotid gland. [1]

  8. Lingual nerve - Wikipedia

    en.wikipedia.org/wiki/Lingual_nerve

    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.

  9. Chorda tympani - Wikipedia

    en.wikipedia.org/wiki/Chorda_tympani

    The facial nerve exits the cranial cavity through the internal acoustic meatus and enters the facial canal. Within the facial canal, chorda tympani branches off the facial nerve and enters the lateral wall of the tympanic cavity within the middle ear , where it runs across the tympanic membrane (from posterior to anterior) and medial to the ...
