Sharma et al described the removal of a parotid duct
calculus with a Dormia basket during sialendoscopy.
It has four or five ducts that open to the side mucosa next to the last upper molar tooth, which contain its roots, the larger duct is almost as big as the parotid duct
, the others are small (DYCE et al.
1 Incise buccal mucosal membrane 1 cm below opening of parotid duct
Intraductal laser photocoagulation of the bilateral parotid ducts
for reduction of drooling in patients with cerebral palsy.
The present study reports on a rare case of anatomic variation of the parotid duct
, which seems to be of some relevance to several diagnostic procedures and surgical interventions on a daily clinic practice.
Parotid salivary duct mucocele and sialolithiasis following parotid duct
Then, triamcinolone was injected into both parotid ducts
Appearance of parotid duct
anlage was observed at 14-18mms CRL Stage as an epithelial invagination in oral epithelium (Merida Velasco 1991).
Posterior compartment--deep to the parotid duct
, contains specialized syssarcosis adipose tissue, a remnant of the succatory fat pad that aids in muscle motion and is of lower CT attenuation and of higher fat signal on MRI than all surrounding fat, including the anterior compartment.
On physical examination, a firm mass below the zygomatic arch on the left cheek was noted, with discharge of purulent saliva from the ostium of the left parotid duct
upon parotid massage.
A thorough review of the available literature reveals that very occasionally other mucosal surfaces like the lips, palate, uvula, maxillary antrum, bronchus, conjunctiva, parotid duct
The risk of injury to the Buccal branch is more, since it has a close relationship to the parotid duct
A congenital salivary fistula from an aberrant parotid duct
However, isolated injury of the parotid duct
without facial nerve injury is rare, and almost all reported cases have occurred in adults following an assault with a knife, bottle, or firearm.
1) A lower incidence of calculi is found in the parotid duct
and in the sublingual duct--up to 20 and 2%, respectively.
