Insights

Anesthesia mumps, or parotid gland swelling, is a rare complication of general anesthesia. This case highlights that even short procedures and standard face mask ventilation can potentially cause this condition.

Area of Science:

  • Anesthesiology
  • Otology

Background:

  • Acute unilateral parotid gland swelling, known as anesthesia mumps, is an uncommon complication following general anesthesia.
  • It is typically associated with prolonged surgical procedures and specific patient positioning.

Purpose of the Study:

  • To report a case of anesthesia mumps occurring after a short-duration surgery.
  • To discuss potential etiologies and emphasize the need for vigilance even in routine cases.

Main Methods:

  • Case report of a 40-year-old female patient.
  • Review of potential causes including gland stasis, duct compression, and air pressure.

Main Results:

  • The patient developed soft tissue swelling in the preauricular and submandibular regions post-operatively.
  • The swelling occurred after a short hysteroscopic myomectomy performed in the lithotomy position.

Conclusions:

  • Anesthesia mumps can occur even after short surgeries and without apparent predisposing factors.
  • Standard face mask ventilation should be considered a potential contributing factor.
