Peggy presented with a history of snoring and exercise-induced respiratory difficulty. No episodes of regurgitation were reported. Following a comprehensive evaluation, she was deemed a good candidate for surgical correction of the nares due to moderate stenotic conformation, with probable elongation of the soft palate to be assessed and confirmed during induction.

Staphylectomy

During induction, the soft palate was observed to be markedly elongated, extending cranially beyond the epiglottic cartilage and causing near-complete obstruction of the laryngeal inlet, severely compromising airflow.

A surgical cut line was pre-marked using a sterile marker during the initial assessment. Lateral sutures were pre-placed prior to resection, and a cut–suture–cut–suture technique was employed to ensure precise apposition of the nasopharyngeal and oropharyngeal mucosa. Closure was achieved using a simple continuous pattern with 2-metric Monocryl.

  • Tonsils: moderately enlarged but non-reactive, slightly everted from the crypts. Removal was not performed, as it was considered that once the staphylectomy eliminated local irritation, the tonsils would return to their normal position within the crypts. Further manipulation and irritation of the area was also judged to increase the risk of post-surgical complications.
  • Laryngeal saccules: normal; no eversion or prolapse observed

Following the staphylectomy, the laryngeal inlet was visibly clear, with the endotracheal tube no longer surrounded by the soft palate.

Nasoplasty

A local block was performed at the nares using a combination of adrenaline and 2% lidocaine (1/9). This provided immediate post-operative analgesia and excellent haemostasis.

A vertical wedge resection of the dorsal alar folds was carried out with a No. 11 scalpel blade following infiltration of 0.3 mL of the adrenaline/lidocaine mixture into each fold. Bleeding was minimal and controlled easily. Closure was completed using simple interrupted sutures, with two stitches placed in the internal ventral nasal mucosa for optimal apposition and symmetry.

No active bleeding was observed at the soft palate surgical site prior to recovery.

Hospitalisation & recovery

Recovery was largely uneventful. Mild upper respiratory noises were noted, attributed to mucus and mild pharyngeal secretions. Peggy remained calm, comfortable and was breathing with a closed mouth.

Post-operative plan

  • Overnight hospitalisation with strict monitoring — Peggy recovered smoothly from surgery and was deemed stable at discharge. She was transferred to a nearby veterinary facility offering overnight (OOH) monitoring.
  • Close observation of airway patency and respiratory effort
  • Continued supportive care to manage potential post-operative swelling or obstruction

This case demonstrates that procedures such as staphylectomy and nasoplasty can be successfully performed in general practice settings. With proper planning and collaboration with OOH services for postoperative care, patients can receive comprehensive treatment without compromising safety or outcomes.
