Palpable hard lump, if the stone is located near the end of the duct. [1] [3] If the stone is near the submandibular duct orifice, the lump may be felt under the tongue. Lack of saliva coming from the duct (total obstruction). [3] Erythema (redness) of the floor of the mouth (infection). [3] Pus discharging from the duct (infection). [3]
They are a relatively common complication following surgery to the salivary glands, [4] commonly parotidectomy (removal of the parotid gland). [5] In this case the sialocele is the result of saliva draining out of remaining parotid tissue, and occurs about 5 to 10% of cases of superficial (partial) parotidectomy. [5] [6]
Oral mucoceles are common, and are caused by rupture of a salivary gland duct and spillage of mucin into the surrounding tissues. Usually, they are caused by trauma. Classically, a mucocele is bluish and fluctuant, and most commonly occurs on the lower lip. [11] Ranula is a mucocele under the tongue.
Thus, sialoendoscopy is an efficient yet simple mode of treatment for major salivary gland obstructions, strictures and sialoliths (salivary stones). Depending on the obstruction, sialoendoscopy can be conducted under local anesthesia in an outpatient office or in the operating room under general anesthesia.
Sialadenitis (sialoadenitis) is inflammation of salivary glands, usually the major ones, the most common being the parotid gland, followed by submandibular and sublingual glands. [1] It should not be confused with sialadenosis (sialosis) which is a non-inflammatory enlargement of the major salivary glands. [2]
The most common use of extracorporeal shockwave therapy (ESWT) is for lithotripsy to treat kidney stones [3] (urinary calculosis) and biliary calculi (stones in the gallbladder or in the liver) using an acoustic pulse. It is also reported to be used for salivary stones [4] and pancreatic stones. [5]

However, the condition may arise anywhere minor salivary glands are located. [nb 1] It has also been occasionally reported to involve the major salivary glands. [2] [3] It may be present only on one side, or both sides. [1] The lesion typically is 1–4 cm in diameter. [4] Initially, the lesion is a tender, erythematous (red) swelling. Later ...
