Surgical and Anesthetic Management of Periorbital Chronic Abscess in Common Hill Myna (Gracula religiosa)

Abstract

Introduction: An abscess is a collection of pus that can cause damage and inflammation and may develop into a painful, life-threatening caseous mass. The present study aimed to report a case series of periorbital chronic abscesses in hill mynas and evaluate the efficacy of the surgical and anesthetic approach used.
Case report: Between 2020 and 2024, five black common hill mynas weighing 286-300 grams and approximately 12 months old were presented to the Sahidul Aalam Quadary Teaching Veterinary Hospital in Chattogram, Bangladesh, with a history of chronic periorbital abscesses. Hill mynas were active and alert on presentation. Based on manual palpation and X-ray examination, all common hill mynas exhibited abscesses, leading to a decision to perform surgery. For anesthesia, 0.5 mL of isoflurane was administered in a gas chamber, and 25 mg/kg of ketamine was administered intramuscularly (IM). During surgery, the caseous mass was successfully removed using the opening method without complications. After one week, mynas received oral pefloxacin at 10 mg/kg of body weight and local application of renamycin ointment (oxytetracycline 3%) twice daily for one week. Four mynas had no complications, with wounds healing without sutures; however, one myna with sutures developed an infection. Wounds healed completely within 15 days without sutures and within 20 days with sutures.
Conclusion: The present study indicated that chronic abscess surgery in common hill mynas was successful without using sutures.
