📚 What Are Stertor & Stridor?

Stertor is low-pitched “snoring” sounds from the nasal passages or throat, often due to soft tissue vibration :contentReference[oaicite:3]{index=3}.

Stridor is a high-pitched wheeze from laryngeal or tracheal narrowing, heard over the larynx and upper airway :contentReference[oaicite:4]{index=4}.

Rabbits—obligate nose-breathers—cannot compensate with mouth breathing, so these sounds signify serious respiratory issues :contentReference[oaicite:5]{index=5}.

⚠️ Why Early Intervention Matters

• Indicates upper airway obstruction that may impair breathing and oxygenation.
• Could signal snuffles, dental abscesses, tumors, trauma, soft-tissue collapse, or neuromuscular issues :contentReference[oaicite:6]{index=6}.
• Untreated obstruction may progress to respiratory distress, pneumonia, or airway collapse.

👀 Recognizing Symptoms

• Stertor: low, snore-like breathing, audible all phases of respiration, often with nasal discharge or sneezing :contentReference[oaicite:7]{index=7}.
• Stridor: high-pitched wheeze, especially on inspiration, sometimes biphasic; signals upper airway narrowing :contentReference[oaicite:8]{index=8}.
• Other signs: audible breathing, nasal or ocular discharge, sneezing, open-mouth breathing, reduced appetite, lethargy.
• Severe obstruction visible via neck extension, labored breathing, cyanosis—needs immediate care.

👣 Causes of Stertor & Stridor

• Snuffles/rhinitis/sinusitis: often Pasteurella infections with nasal discharge and blockage :contentReference[oaicite:9]{index=9}.
• Dental disease: elongated roots or abscesses impinging nasopharynx :contentReference[oaicite:10]{index=10}.
• Nasopharyngeal masses: polyps, tumors causing airway obstruction :contentReference[oaicite:11]{index=11}.
• Upper airway collapse or redundancy: flaccid soft palate or pharyngeal tissue :contentReference[oaicite:12]{index=12}.
• Trauma or foreign bodies: plant material lodged in nasal passages/trachea :contentReference[oaicite:13]{index=13}.
• Neoplasia: nasal, nasopharyngeal or laryngeal tumors like thymomas causing congestion :contentReference[oaicite:14]{index=14}.
• Neuromuscular or anatomical defects: rare, including nerve dysfunction and congenital anomalies :contentReference[oaicite:15]{index=15}.

🔍 Diagnostic Pathway

• History & physical exam: note onset, other signs, worsen with stress/exertion.
• Listen for noise zones—pharynx (stertor) vs larynx (stridor) using careful auscultation :contentReference[oaicite:16]{index=16}.
• Otoscopy/nasal exam under sedation; oral/dental check for root involvement :contentReference[oaicite:17]{index=17}.
• Imaging: skull and neck X‑rays; CT scan ideal for tumors or abscess assessment.
• Rhinoscopy or endoscopy: direct visualisation and biopsy of masses, foreign bodies :contentReference[oaicite:18]{index=18}.
• Lab work: CBC/chemistry for systemic infection; cultures to tailor antibiotics.

🛠️ Treatment Strategies

1. Underlying Cause

• Antibiotics & anti-inflammatories: for infection—fluoroquinolones or trimethoprim-sulfa safe for rabbits :contentReference[oaicite:19]{index=19}.
• Dental abscesses: extraction and abscess drainage or surgical removal.
• Masses or polyps: surgical excision or biopsy for neoplasia.
• Foreign body removal: via endoscopy or surgery if lodged.
• Tissue redundancy: surgical epiglottoplasty or rhynoplasty to remove floppy tissues :contentReference[oaicite:20]{index=20}.

2. Support & Airway Management

• Ensure calm environment and upright posture to ease breathing.
• Supplemental O₂ if hypoxic or distress present.
• Nebulisation with saline ± mucolytics to clear secretions :contentReference[oaicite:21]{index=21}.

3. Emergency Intervention

• Severe stridor may necessitate sedation and intubation or emergency tracheostomy :contentReference[oaicite:22]{index=22}.
• Monitor oxygen, use cooling and minimal handling to avoid stress.

🏠 Home Care & Monitoring

• Maintain humidified environment; avoid irritants like dust or smoke.
• Monitor noise, breathing rate, appetite, activity daily.
• Continue meds fully, follow-up imaging when treatment concludes.
• Clean discharge from nose/eyes gently; watch for recurrence.

📊 Prognosis & Outcomes

• Infection or foreign body cases often resolve well with treatment.
• Surgical resolution of dental or sinonasal disease has good outlook.
• Masses carry more uncertainty; may recur or require ongoing care.
• Severe airway collapse may need repeat intervention.

🛡️ Prevention & Risk Management

• Routine dental check every 6 months; treat early root disease.
• Keep housing clean, dust-free; avoid allergens and irritants.
• Supervise free-roam areas—remove small sticks or cord hazards.
• Promptly treat snuffles to prevent chronic airway changes.

🧠 Vet Tips for 2025

• Screen for upper airway sounds during wellness exams.
• Educate owners on breathing noise types, urgency, and response.
• Schedule imaging/endoscopy early when stridor persists.
• Prepare emergency airway kits and sedation protocols.
• Offer telehealth check-ins to monitor respiratory recovery progress.

🔚 Final Takeaway

Stertor and stridor in rabbits indicate serious upper airway issues—from infection and obstruction to structural collapse. In 2025, timely diagnosis, treatment, and home support can significantly improve outcomes. Maintaining airway health ensures your bunny can breathe easy and thrive. 🐇❤️
