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.
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.
