Submandibular Gland Abscess

 Abscess presenting as fluctuant tender swelling of left submandibular area.

Copious thick pus discharge from left submandibular duct opening.

Submandibular Duct Calculi with Floor of Mouth Cellulitis

The  majority of submandibular salivary gland calculi are radiopaque and visible on X-ray.  This patient has inflamed and swollen left floor of mouth with pus emanating from the Wharton's duct.  Intraocclusal view showed at least 2 radiopaque stones with the bigger one situated more anteriorly. 

Stone retrieved from the submandibular duct.

A longstanding distal submandibular duct calculi (X) in a patient presenting with episodic left submandibular swelling during meals.

CT-scan view showing a significant size radiopaque calculi along left submandibular duct anatomy.  History revealed repeated non-painful left submandibular swelling while eating which subsides slowly.

Another example of distal submandibular duct calculi just beyond its opening. (LI 1 - left 1st incisor, RI 1-right 1st lower incisor, RI 2 - right 2nd lower incisor)

Salivary Duct Stone Surgery As An Outpatient Procedure

 

In this video, the left submandibular duct was blocked by a small stone (calculi) which had caused infection of the gland with pus formation.  Imaging study showed no evidence of calculi within the gland itself and the implicated stone was located just before the natural duct opening.  Local anaesthesia infiltration was given followed by incision using radiofrequency device along the long axis of the duct where the stone felt (the natural duct opening was spared).  Pus gush out as the duct lumen reached.  Careful suctioning and manipulation enable the small stone to be retrieved (attached to suction device end).  The opening was left unsutured as it can healed readily.  An antibiotic course and mouth rinse were prescribed.

 Incision made using scalpel blade (SB) along the long axis of the duct.

 Submandibular duct opened by using small artery forceps to reveal the calculi (arrow).

Parotid Abscess with Salivary Sinus

Arrow - sinus emanating clear salivary fluid upon eating surrounded by induration.  CT-scan showed bilateral bilateral parotitis.  The patient had two similar infections within two years.  Tuberculosis was ruled out.

CT-Sialogram

 Combination of CT-scan and sialogram allows simultaneous assessment of salivary gland drainage patency and intrinsic parenchymal salivary lesions.  [green arrow - distal Stensen's duct heading towards its opening opposite upper second molar tooth, yellow arrow - sialogram contrast well distributed inside right parotid gland, white arrow- parotid duct lying in outer surface of masseter muscle].
