Gleason et al: Ala vestibuloplasty improves cardiopulmonary and activity‐related parameters in brachycephalic cats
Veterinary Surgery 4, 2023

🔍 Key Findings

  • Ala vestibuloplasty significantly reduced normalized pulmonary transit time (nPTT) (mean 5.43 → 3.89 sec; p <.001), suggesting improved cardiopulmonary function.
  • Clinical respiratory signs improved, including reduced snoring, sneezing, nasal discharge, and open-mouth breathing (all p <.01).
  • Activity tolerance increased, with less dyspnea during activity and longer time to onset of dyspnea (p <.005).
  • Paradoxical sternal motion resolved in all affected cats after surgery.
  • Hiatal hernias resolved in 75% of affected cats on follow-up CT.
  • No serious complications occurred, with only mild, self-limiting epistaxis and hypersalivation in a few cases.
  • Aberrant turbinates were detected on CT in all cats, though only 1 showed obstructive CATs endoscopically.
  • Total clinical severity scores improved significantly postoperatively (median reduction of 30 points; p <.001).
