Parotitis After Epidural Anesthesia in Plastic Surgery: Report of Three Cases

Abstract

Acute swelling of the parotid glands after general anesthesia has become known as anesthesia mumps. Its cause is unknown. Only one case of postsurgical parotitis without general anesthesia is reported. This report describes three cases in this setting after plastic surgery. A 37-year-old women underwent breast surgery and abdominoplasty with a dual thoracic/lumbar epidural block (bupivacaine 0.5%). The operative time totaled almost 6h. Subsequently, 4h after surgery, the patient experienced painless bilateral parotid swelling without palpable crepitus. The edema resolved completely within 12h under clinical observation and parenteral hydration. A 45-year-old patient received subglandular breast implants and body contouring with liposuction, all with the patient under a dual thoracic/lumbar epidural block with 0.5% marcaine. The total surgical time was 5h. Subsequently, 3h after surgery, the patient experienced a similar clinical presentation. The problem resolved completely in 36h with clinical observation and parenteral hydration. CASE 3: A 30-year-old patient received a subglandular breast implant and underwent liposuction of the outer thighs using a dual thoracic/lumbar epidural block with lidocaine 1%. The duration of surgery was 1h. Subsequently, 5h postoperatively, the patient experienced a similar clinical presentation. Dexamethasone and parenteral hydration were administered. The problem resolved completely in 48h without sequelae. The occurrence of parotitis in patients undergoing surgery under epidural anesthesia is a novel situation, which increases the range of possible etiologies for this little known condition. Dehydration leading to transient parotid secretion obstruction may play a significant role. Further reports of parotitis occurring in the regional anesthesia setting are expected to help elucidate its pathophysiology.
