Acute transient sialadenopathy associated with anesthesia

Anesthetic mumps; A rare complication after surgery

“…[6] Salivary gland enlargement; It has been identified as a unique side effect of many drugs, including analgesics, anti-histamines, muscle relaxants (succinylcholine), sedatives, and phenothiazine derivatives. [7][8][9][10] Atropine may play a role in parotid gland enlargement by causing stenosis of the salivary glands, causing thick and viscous saliva. [10] Preoperative dehydration is thought to cause more intense secretion and predispose to salivary duct obstruction.…”

“…[7][8][9][10] Atropine may play a role in parotid gland enlargement by causing stenosis of the salivary glands, causing thick and viscous saliva. [10] Preoperative dehydration is thought to cause more intense secretion and predispose to salivary duct obstruction. [11,12] In addition, it may cause mechanical obstruction of the parotid canal with fixation of the endotracheal tube after intubation or the inability to evacuate the secretion and temporary parotid gland enlargement due to the traumatization of the parotid canal.…”

Effects of anaesthesia using endotracheal intubation or the laryngeal mask airway, or spinal anaesthesia, on oral mucosal host defences during minor surgery

“…ET using a laryngoscope, by contrast, is more damaging to the oral mucosa than blind insertion of the LMA and may even cause direct tissue trauma (16, 17). Transient salivary gland enlargement has been reported after ET (18–20), but transient swelling may also occur after insertion of a laryngeal mask (21, 22).…”

Bilateral parotid swelling: A review

“…Simultaneously, agents such as succinylcholine used as a muscle relaxant during the anesthetic procedure cause a loss of muscle tone around the Stensen orifice. 104,105 The flaccid musculature facilitates the retrograde passage of air into the parotid gland when the positive pressure in the oral cavity is significantly increased. Crepitation ascertained by palpation, a sign of tissue emphysema, is usually present and confirms the existence of an airdistended parotid gland.…”
