Upper Respiratory Obstruction and Inflammation

This content covers common upper respiratory issues such as nasal polyps, pharyngitis, tonsillitis, laryngeal polyps, laryngitis, and the critical condition of airway obstruction, including their causes, manifestations, and management.

The upper respiratory tract serves as the critical gateway for air entering the body, encompassing structures from the nasal cavity through the pharynx and larynx. Because these structures are exposed to the external environment, they are highly susceptible to inflammation, infection, and physical obstructions. Understanding the progression from mild inflammation to life-threatening airway obstruction is essential for clinical assessment and rapid intervention.

Nasal Polyps and Sinus Obstruction

Inflammation of the nasal mucosa can lead to various complications, including the development of nasal polyps. These are benign growths that typically arise from chronic inflammation. While they are not cancerous, their size and location can significantly impact a patient's quality of life and respiratory function.

Large nasal polyps can cause physical obstruction of the nasal passages, leading to persistent discharge, difficulty breathing through the nose, and even speech distortion. Management of these polyps often involves the use of corticosteroids to reduce swelling, though surgical interventions such as endoscopic or laser surgery may be required for larger growths.

Pharyngeal Inflammation: Pharyngitis and Peritonsillar Abscess

The pharynx—comprising the tonsils, palate, and uvula—is a frequent site of inflammation known as pharyngitis. The etiology of pharyngitis is diverse: approximately 90% of cases are viral, while others may be bacterial (such as "strep throat"), fungal (candidiasis), or caused by environmental irritants like dry air, smoking, or GERD.
