Differential Diagnosis for Snorting Sounds

• Single most likely diagnosis
  • Allergic rhinitis: This condition is characterized by inflammation of the nasal passages, often due to allergies, leading to congestion and snorting sounds as the individual tries to clear their airway.
• Other Likely diagnoses
  • Nasal polyps: Growths in the nasal passages can cause obstruction, leading to breathing difficulties and snorting sounds.
  • Deviated septum: A crooked partition between the nostrils can cause uneven airflow, resulting in snorting or noisy breathing.
  • Upper respiratory infection: Common colds or sinus infections can cause nasal congestion, leading to snorting sounds.
• Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
  • Epiglottitis: Inflammation of the epiglottis can cause severe respiratory distress, and while less common, it's a potentially life-threatening condition that requires immediate attention.
  • Foreign body in the airway: An object lodged in the nasal passage or airway can cause sudden onset of snorting sounds and is a medical emergency.
• Rare diagnoses
  • Tumors of the nasal cavity or sinuses: Although rare, tumors in the nasal passages can cause obstruction and lead to snorting sounds.
  • Granulomatosis with polyangiitis (formerly known as Wegener's granulomatosis): A rare autoimmune disorder that can affect the nasal passages and sinuses, leading to symptoms including snorting sounds.
