Submandibular and Submandibular and Sublingual gland innervationSublingual gland innervation
Superior salivatory nucleus - nervus intermedius - facial nerve - chorda tympani - lingual nerve - submandibular ganglion - submandibular/lingual glands

Parotid innervationParotid innervation
Inferior salivatory nucleus - glossopharyngeal nerve - Jacobsen’s nerve - lesser superficial petrosal nerve - otic ganglion - auriculotemporal nerve

Salivary gland innervationSalivary gland innervation
Parasympathetic system stimulation causes an increase in saliva flow from all glands
Sympathetic system stimulation causes increase in saliva flow from submandibular gland but has no effect on parotid flow

Surgical indicationsSurgical indications
Age 5-6 Failed non-surgical management > 6
months Stable neurological status Drooling with non-operative patient

Surgical contra-indicationsSurgical contra-indications
High risk for operation unilateral HL for tympanic neurectomy Rerouting of salivary duct in esophagus
disoerder, ch. aspiration

Wilke procedure - 1967Wilke procedure - 1967
Bil. submandibular gland exc. And bil. Parotd duct relocation.
Success rate 85% Postoperative complication (35%) and high
morbidity Modification of the procedure

Submandibular Gland Submandibular Gland Excision + partid duct Excision + partid duct ligationligation
High success rate(85 – 100%)- (Shot) Very common Low morbidity Mild swelling of face, external scars, xerostomia ,
parotitis

Parotid duct ligationParotid duct ligation
Location of the pappila , insert lacrimal probe
Elliptical incision made around the parotid duct. Duct dissected for 1 cm, suture ligated and resected. The buccal mucosa is then repaired.

Rerouting of submandibular Rerouting of submandibular ductduct
Cuff of mucosa dissected around duct and marked medially and laterally
Duct dissected 3-4 cm or until gland reached Tonsil used to create a tunnel just posterior to
anterior tonsillar pillar and sutures passed with duct
Tonsillectomy performed if obstructive tonsils

Rerouting of submandibular Rerouting of submandibular duct(cont’d)duct(cont’d)
relocation in base of ant. Pillar : no need for TE , less infection
Rate success 80-100% Sublingual gland exc. Advantages: Decreased xerostomia, problems with
taste and dysphagia Disadv: Ranula, sialoadenitis, sialolithiasis,
aspiration pneumonia

Studies on submandibular Studies on submandibular duct reroutingduct rerouting
Crysdale - 8% ranula rate O’Dywer - 15 year follow -up study, 94%
of parents stated their child benefited, 50% had complete cessation of drooling

Transtympanic neurectomiesTranstympanic neurectomies
80% success rate Must take both chorda and tympanic plexus Hypotympanic branch in 50% of patients Low speed drill Loss of taste in anterior 2/3 of tongue and
xerostomia Contraindicated in unilateral SNHL
