Soft Palate & Nostril Surgery for Flat-Faced Dogs

The two most impactful steps in treating brachycephalic breathing problems are opening pinched nostrils and shortening an over-long soft palate. Dr. Antonio Pedraza performs these minimally invasive, laser-assisted corrections in Santa Monica.

• BOAS
• Soft palate
• Nostrils
• Laser surgery

For most flat-faced dogs with brachycephalic obstructive airway syndrome (BOAS), the biggest gains in breathing come from two corrections: widening narrowed nostrils and trimming and thinning an elongated soft palate. These are the structures that block airflow the most — narrowed nostrils affect roughly half of French Bulldogs, and an over-long soft palate is the single most common finding, present in up to ~87% of affected dogs. Because most patients have both problems, the two are usually corrected together in one carefully planned procedure. At Los Angeles Laparoscopy Vet, Dr. Pedraza uses CO₂ laser and energy devices with high-definition visualization to do this precisely and gently. Whether your dog needs one or both depends on an individual evaluation.

What is soft palate and nostril surgery?

It's a pair of airway corrections that make more room to breathe. Nostril surgery widens the narrowed nasal openings at the front of the airway; soft palate surgery shortens (and, with some techniques, thins) the excess tissue at the back of the mouth that partly blocks the throat. They address the two most common and most obstructive problems in BOAS, which is why they form the core of brachycephalic airway surgery.

Why do the nostrils and soft palate matter most?

Because they create the greatest resistance to airflow. Pinched (stenotic) nostrils dramatically increase the effort it takes to breathe in — moderate-to-severe narrowing can multiply airflow resistance many times over. An elongated soft palate, the most frequent abnormality in these dogs, hangs into the airway and flutters with each breath, causing the classic snoring and snorting. Relieving both removes the bulk of the obstruction for most patients.

What is nostril surgery (rhinoplasty / alaroplasty)?

It reshapes the nostril openings so air can pass more easily. The surgeon removes a small wedge of tissue from the side of each nostril (or uses related techniques) to widen the opening. It's one of the highest-value, lowest-risk steps in BOAS surgery and is frequently done at the same time as soft palate surgery. Using laser can keep bleeding to a minimum.

What is soft palate surgery (staphylectomy / folding-flap palatoplasty)?

It removes the excess length of the soft palate so it no longer obstructs the throat. A traditional staphylectomy trims the over-long edge; a folding-flap palatoplasty also reduces the palate's thickness, which can help dogs whose palate is not just long but bulky (common in French Bulldogs). Dr. Pedraza selects the technique to match your dog's anatomy.

Are the saccules and tonsils treated too?

Sometimes. Chronic obstruction can cause small pouches near the voice box (laryngeal saccules) to turn outward, and the tonsils to evert, adding to the blockage. When these are contributing, they can be removed during the same procedure. Whether that's needed is judged at the time of evaluation and surgery.

Why CO₂ laser and energy devices?

Airway tissue is delicate and prone to swelling, and the working space is small. CO₂ laser and energy (vessel-sealing) instruments can cut and seal at the same time, which tends to reduce bleeding and shorten surgical time compared with traditional cutting and suturing — while high-definition visualization helps the surgeon work precisely. Less bleeding and trauma can support a smoother early recovery, though results always depend on the individual dog.

What is recovery like?

Most dogs are monitored closely on the day of surgery and go home with a written care plan. The early recovery period is typically about one to two weeks, with calm activity, careful feeding (often softened food at first) and strict heat avoidance while swelling settles. Many owners notice quieter, easier breathing soon after healing. Dr. Pedraza provides specific instructions and a direct follow-up.

What results can we expect?

Owners commonly report clear improvement in breathing, energy and sleep, and in many studies the large majority of families see their dog do better. To be candid, surgery improves the airway rather than making a flat-faced dog's anatomy normal, and some dogs remain partially affected — especially if advanced secondary changes are already present. Lifelong weight and heat management stay important.
