To compare outcomes and short-term complications of dogs with laryngeal paralysis treated with unilateral arytenoid lateralization performed on an outpatient versus inpatient basis.


44 client-owned dogs.


Medical records were retrospectively reviewed to identify dogs that underwent unilateral arytenoid lateralization for the treatment of laryngeal paralysis between 2018 and 2022. Signalment, surgical technique, anesthesia time, comorbidities, laryngeal examination, concurrent procedures, use of prokinetics and sedatives, episodes of vomiting, episodes of regurgitation, duration of hospitalization, postoperative complications, anxiety scores, and pain scores were recorded. Variables were compared between dogs and grouped by outpatient or inpatient management.


The overall complication rate was 22.7% (10/44), with 35% (7/20) being in the inpatient group and 12.5% (3/24) being in the outpatient group. The overall mortality rate was 6.8% (3/44). The overall morbidity for hospitalized patients versus those undergoing and outpatient procedure was 5% (1/20) and 4.2% (1/24), respectively. There was no significant difference between overall rate of complications and mortality rates between the inpatient and outpatient groups.


Results suggested that outpatient management of dogs with laryngeal paralysis treated with elective unilateral arytenoid lateralization is an appropriate method of postoperative management with no difference in complication or mortality rates. Further prospective studies with standardized surgical, sedative, and antiemetic protocols are warranted to evaluate more definitely.
