Introduction

  • Conventional surgeries to treat brachycephalic obstructive airway syndrome (BOAS) include staphylectomy, rhinoplasty, and laryngeal sacculectomy. However, these surgeries do not address intranasal obstruction and therefore some dogs may still experience ongoing respiratory signs.
  • Laser-assisted turbinectomy (LATE) is a minimally-invasive, effective, surgical technique that can treat persistent intranasal obstruction resulting from aberrant and hypertrophic nasal turbinates in brachycephalic dogs.
The procedures and perioperative care are highly specialized. Referral to a specialist with experience in these techniques is therefore advised.

Uses

  • Brachycephalic dogs Brachycephalic obstructive airway syndrome (BOAS) with rostral and/or caudal aberrant nasal turbinates that cause significant intranasal obstruction and associated clinical signs (eg mouth-breathing at rest; sleep apnea; severe heat intolerance).

Advantages

  • Minimally-invasive procedure which can effectively alleviate intranasal obstruction, complementing conventional surgical procedures for BOAS.
  • Ability to coagulate blood vessels during the procedure.
  • Major complications are rare.

Disadvantages

  • Expensive equipment required.
  • Health and safety implications of laser use.
  • Steep learning curve.
  • Can be difficult to perform LATE on toy breed dogs due to the small size of the nasal cavity.
  • May compromise thermoregulatory function due to excessive reduction of mucosal surface area on nasal turbinates.
  • Turbinate regrowth may occur and repeat turbinectomy may be required.
