Objective: To report the prevalence and document the treatment and outcome of odontogenic abscesses and associated jaw osteomyelitis in pet rabbits.
Animals: 200 client-owned rabbits.
Methods: Pet rabbits surgically treated using extraoral teeth extraction with marsupialization for abscesses of dental origin and jaw osteomyelitis were included in the study (February 2018 to February 2023). A case must have had pre- and postoperative computed tomographic study and a follow-up period of at least 4 months.
Results: In total, 113 male and 87 female rabbits were treated surgically. The mean age at the time of the diagnosis at the authors' clinic was 3 years and 11 months. Male rabbits suffered from odontogenic abscesses significantly more often than females. The mean surgical time varied from 25 to 95 minutes, based on the severity of the pathology and location. The wound healed completely in an average of 39.7 days (range, 14 to 145 days; 95% CI, 36.9 to 42.5 days). Major complications detected in 18.5% (37/200) cases were associated with prolonged healing time mostly due to the formation of a bone sequestrum and gingival suture failure. The disease-free time following abscess resolution was on average 29 months (range, 4 to 60 months). The recurrence of the odontogenic infection was 8% (16/200 cases).
Clinical relevance: The radical surgical technique with the extraction of all the infected teeth with the removal of all affected tissue and osteomyelitic bone and regular follow-up wound management is an effective method for the treatment of odontogenic abscesses with jaw osteomyelitis.
