Plain-English summary
Eighty dogs with laryngeal paralysis underwent surgery to help them breathe better, using either a standard technique or a newer method that preserves more anatomy. After surgery, some dogs had minor complications, but most owners reported that their pets improved and were satisfied with the results. The risk of developing aspiration pneumonia (a lung infection) was similar for both techniques, and the average survival time was about 636 days for the standard method and 1067 days for the newer method. Overall, both surgical options were effective, with many dogs showing positive outcomes.

Abstract
The purpose of this study is to compare the rate of aspiration pneumonia and survival time of dogs undergoing two unilateral arytenoid lateralisation (UAL) techniques.Eighty dogs diagnosed with laryngeal paralysis were treated by one of two UAL techniques: (1) a standard technique (ST) and (2) an anatomic preservation technique (APT). Outcome was assessed by in clinic re-examination and an owner follow-up questionnaire.Minor complications were reported for 22 per cent of dogs undergoing ST and 26 per cent for APT. Major complications were 7 per cent for ST versus 23 per cent for APT. Postoperative aspiration pneumonia was reported for 7 per cent of cases in ST and 17 per cent in APT. The median survival time for ST was 636 days and was 1067 days for APT. Cause of death was related to the laryngeal paralysis in 22 per cent, neurological deterioration in 16 per cent and for non-associated reasons in 59 per cent of cases. There was no statistically significant difference in the rate of aspiration pneumonia or survival time among the treatment groups. Owners reported that their dogs improved after both surgical procedures, with 90 per cent of the owners satisfied with the surgical outcome. Eighteen per cent of the dogs suffered recurrence of clinical signs.In this study, there was no significant difference in risk of aspiration pneumonia or survival time following arytenoid lateralisation by either an ST or an APT.
