8. SALIVARY
GLANDS
Besides
the parotid glands, salivary tissue is found
in the
submaxillary glands
lingual glands and other
minor salivary
glands in the mouth.
8.1 PAROTID
GLAND
The
parotid gland is
U-shaped and wraps itself
around the
ascending ramus of the mandible .
The larger
portion of the gland is the superficial lobe.
The smaller
portion is the deep lobe.
The VIIth
nerve divides into its branches in the parotid gland.
Branches eventually leave the parotid
gland and course across the
masseter muscle. Tumours commonly occur
in the superficial lobe.
8.2
SUBMANDIBULAR GLAND
Submandibular gland
is an avoid
structure, lying in
the
submandibular fossa, beneath horizontal
ramus of the mandible and
bounded
by the anterior and posterior
belly of
the diagstric
muscle.
The lowest
branches of the VIIth nerve courses over the gland.
Lingual
nerve is deep to inferior durface of
the submandibular
gland, both these nerves are at risk
during surgery Fig.14.4a &
14.4b
8.3 THE
LINGUAL GLAND
Lies beneath the mucosa of the anterior
part of the floor of the
mouth on either side of the frenulum of
the tongue.
Most of the lesions occur in the parotid
glands, the second most
common being the mandibular gland
