The triangle of Farabeuf is bounded by the internal jugular vein ( posterior ), common facial vein ( anterior-inferior ) and hypoglossal nerve ( anterior-superior ).
22.
The benign tumors of the submandibular gland is treated by simple excision with preservation of mandibular branch of the trigeminal nerve, the hypoglossal nerve, and the lingual nerve.
23.
However, after the use of the hypoglossal nerve control of facial movements is hard to obtain by the patient and a spontaneous smile may not occur at all.
24.
If a free muscle transfer is indicated, this is also performed in the second stage of the procedure to augment the partially reinnervated mimic muscles by the hypoglossal nerve.
25.
The nuclei of the glossopharyngeal nerve ( IX ), vagus nerve ( X ), accessory nerve ( XI ) and hypoglossal nerve ( XII ) are located in the medulla.
26.
An area in the neck sometimes called the Pirogov triangle is formed by the intermediate tendon of the digastric muscle, the posterior border of the mylohyoid muscle, and the hypoglossal nerve.
27.
*Motor supply for all intrinsic and extrinsic muscles of the tongue is supplied by efferent motor nerve fibers from the hypoglossal nerve ( CN XII ), with the exception of the palatoglossus.
28.
Laterally, in between the hyoglossus muscle and the mylohyoid muscle lay several important structures ( from upper to lower ) : sublingual gland, submandibular duct, lingual nerve, vena comitans of hypoglossal nerve, and the hypoglossal nerve.
29.
In the neck, its origin is superficial, being covered by the integument, platysma, and fascia; it then passes beneath the digastric and stylohyoid muscles and part of the submandibular gland, but superficial to the hypoglossal nerve.
30.
In the upper part, the carotid sheath also contains the glossopharyngeal nerve ( IX ), the accessory nerve ( XI ), and the hypoglossal nerve ( XII ), which pierce the fascia of the carotid sheath.
