Snoring Without Adenoids: Causes, Risk Factors & Solutions

Adenoidectomy does not guarantee snoring resolution. Snoring arises from vibration of pharyngeal soft tissues during turbulent airflow — multiple anatomic and physiologic factors contribute.

Common Causes (Independent of Adenoids)

• Palatine tonsil hypertrophy (especially children)
• Nasal obstruction: Deviated septum, turbinate hypertrophy, polyps, allergic rhinitis
• Soft palate/uvula elongation or redundancy
• Macroglossia / retrognathia / micrognathia (craniofacial structure)
• Obesity: Parapharyngeal fat deposition → airway narrowing
• Alcohol/sedatives: ↓ pharyngeal tone
• Smoking: Airway inflammation, edema
• Supine position: Gravity-dependent collapse
• OSA: Recurrent collapse → apneas/hypopneas; snoring is cardinal symptom

Evaluation

• History: witnessed apneas, gasping, unrefreshing sleep, daytime sleepiness (ESS).
• Exam: nasal endoscopy, oropharyngeal crowding (Mallampati, Friedman), BMI.
• Sleep study (PSG or HSAT) if OSA suspected.

Management

• Conservative: Weight loss, lateral sleep, avoid alcohol/sedatives 3h pre-bed, treat nasal obstruction (sprays, allergy control).
• Oral appliance (MAD): Advances mandible → opens airway; mild-moderate OSA.
• CPAP: Gold standard for moderate-severe OSA.
• Surgery: UPPP, nasal surgery, hypoglossal nerve stimulation, MMA — selected cases.

Snoring ≠ benign. Screen for OSA (STOP-BANG). Treat the cause, not just the noise.
