Recurrent Bilateral Anesthesia Mumps after Cesarean Section Under Spinal Anesthesia, Rare Case Report and Literature Review.

Anesthesia mumps, also known as acute postoperative sialadenitis, is a rare complication that can occur following general or regional anesthesia. The prevalence of this condition ranges from 0.16% to 0.2%. This case report presents a patient with recurrent bilateral parotid swelling after cesarean section (CS) under spinal anesthesia and its management. A 42-year-old G5P4 woman with gestational diabetes mellitus and antiphospholipid syndrome presented for elective cesarean delivery at 39 weeks and two days of gestation under spinal anesthesia. The patient developed bilateral facial swelling after five hours, which was more evident on the right parotid site. A review by an otolaryngologist confirmed the diagnosis of anesthesia mumps. Anesthesia mumps typically presents as painless swelling of the salivary glands. Salivary duct obstruction and hyperemia are believed to be common causes. This case highlights that anesthesia-induced mumps is a reversible and transient complication that may occur after short surgical procedures, such as cesarean sections. Early recovery was achieved following supportive conservative management, with hydration and analgesia.
