Acute unilateral anesthesia mumps after hysteroscopic surgery under general anesthesia: a case report

Abstract

Acute unilateral parotid gland swelling after general anesthesia, anesthesia mumps is rare and when occurred, it is associated with the patient's position and with long-lasting surgery. The exact mechanism or etiology has not been fully established but stasis of gland secretion, blockage of Stensen's duct by direct compression, or retrograde flow of air by increased the oral cavity pressure are suspicious reasons. We experienced a case of soft tissue swelling in the left preauricular and submandibular regions in a 40-year-old female patient after short-lasting, hysteroscopic myomectomy performed in the lithotomy position with no suspicious predisposing factor. It is required to pay attention on the fact that even with the usual face mask ventilation can lead to the development of anesthesia mumps.

Bilateral Anesthesia Mumps After Robot-Assisted Hysterectomy Under General Anesthesia: Two Case Reports

“…Acute parotid gland swelling or "anesthesia mumps" is a rare peri-or post-operative condition that has been reported in several studies [3,[5][6][7][8][9][10][11]. The exact mechanism underlying the development of anesthesia mumps is not clear, but there are several hypotheses: theoretically, in conditions causing salivary stasis, secondary salivary infection could occur due to mechanical obstruction of the salivary duct; a medical condition, such as diabetes mellitus, hepatic failure, renal failure, hypothyroidism, Sjögren's syndrome, depression or malnutrition could underlie development of anesthesia mumps; the use of perioperative medications, such as anticholinergic agents, could cause this condition; or it could result from dehydration.…”

“…Straining or coughing during or after anesthesia may increase positive pressure in the oral cavity. Furthermore, peri-operative dehydration and use of muscle relaxants (succinylcholine) or anticholinergics (glycopyrrolate) increase the risk of a loss of muscle tone around Stensens' duct, which can in turn result in retrograde passage of air into the parotid gland [2,5,8].…”

“…Anesthesia mumps refers to a rare post-operative acute parotid gland swelling that usually resolves within a few days [1][2][3]. The first report of anesthesia mumps was by Attas in 1969 [4], and many subsequent cases have been reported during thyroidectomy, spinal surgery, plastic surgery, gynecological surgery, neurosurgery, thoracotomy and nephrectomy [3,[5][6][7][8][9][10][11]. However, the etiology of anesthesia mumps remains unknown, although conditions causing salivary duct stasis may be responsible [12].…”

Development of acute parotitis after non-invasive ventilation

“…General anesthesia has long been identified as a rare cause of acute parotitis ("anesthesia mumps"). This entity is typically bilateral (14,15), but has also been reported as a unilateral occurrence (16).…”

A complication after percutaneous nephrolithotomy: Anesthesia mumps

“…Acute transient swelling of the parotid gland related to anesthesia, defined as “anesthesia mumps,” is a benign and noninfectious complication. [ 1 ] It is a rare clinical entity observed immediately following general anesthesia or even after epidural anesthesia. [ 2 ] Besides, it is interesting to observe that even the usual face mask ventilation can lead to the development of anesthesia mumps.…”
