Abstract
in English, French

This retrospective study assesses postoperative complications with simultaneous staphylectomy and unilateral arytenoid lateralization (SP + UAL) in dogs with laryngeal paralysis and concurrent elongation of the soft palate compared to dogs having a UAL alone. Medical records of dogs having a UAL performed from 2010 to 2013 were reviewed. Twenty-three dogs were diagnosed with a concurrent elongated soft palate and had a SP + UAL performed and 89 dogs were diagnosed with an appropriate soft palate and had only a UAL performed. A telephone questionnaire for long-term postoperative outcomes was completed. Survival probability was not statistically different between the 2 groups. Dogs in the SP + UAL group were more likely to be seen for respiratory distress after surgery (P = 0.05). There was no significant difference between the 2 groups in the number of dogs which developed postoperative aspiration pneumonia. The overall complication rate for both groups was high, with postoperative pneumonia being the most common complication.

Staphylectomie et latéralisation unilatérale de l’arythénoïde simultanées chez des chiens manifestant de la dyspnée : 23 cas (2010–2013). Cette étude rétrospective évalue les complications postopératoires associées à une staphylectomie et à une latéralisation unilatérale de l’arythénoïde (SP + LAU) simultanée chez des chiens atteints de paralysie laryngée et d’allongement concomitant du palais mou comparativement à des chiens atteints seulement de LAU. Les dossiers médicaux de chiens qui avaient subi une LAU de 2010 à 2013 ont été examinés. Vingt-trois chiens ont été diagnostiqués avec un palais mou allongé concomitant et ont subi une SP + LAU et 89 chiens ont été diagnostiqués avec un palais mou conforme et avaient subi seulement une LAU. Un questionnaire téléphonique pour les résultats postopératoires à long terme a été rempli. La probabilité de survie n’était pas statistiquement différente entre les deux groupes. Il était plus probable que les chiens du groupe SP + LAU soient examinés pour une détresse respiratoire après la chirurgie (P = 0,05). Il n’y avait pas de différence statistiquement significative entre les deux groupes quant au nombre de chiens qui ont développé une pneumonie de déglutition postopératoire. Le taux de complication global était élevé pour les deux groupes et la pneumonie postopératoire était la complication la plus fréquente.(Traduit par Isabelle Vallières).

Kaplan-Meier survival curve analysis of the simultaneous staphylectomy and unilateral arytenoid lateralization (SP + UAL) group and the unilateral arytenoid lateralization (UAL) only group. The number of dogs in each group at different time periods is indicated just above the x-axis. A log-rank test was used to compare statistical significance (P = 0.32); survival curves were not statistically different between the 2 groups of dogs.
