R06.5

Clinical Causes: Nasal congestion due to allergies or infections Structural abnormalities in the nasal passages or sinuses, such as a deviated septum Enlarged adenoids or tonsils, especially in children Chronic sinusitis or nasal polyps Habitual mouth breathing developed over time Obstructive sleep apnea Loose or obstructed nasal tissues or structures Environmental factors like dry air or pollution causing nasal irritation

Key Symptoms: Dry mouth and sore throat Bad breath Persistent nasal congestion or blockage Difficulty sleeping or frequent awakenings at night Snoring Altered facial development in children, such as a longer face or dental malocclusion Reduced sense of smell Breathing through the mouth during daytime or sleep Facial swelling or skin irritation around the mouth

Diagnosis Path: Inspection of the oral cavity and nasal passages Assessment of breathing patterns Imaging studies such as X-rays or nasal endoscopy to evaluate nasal structure Sleep studies if sleep-related breathing issues are suspected Allergy testing to identify contributing allergic reactions

Treatment Protocols: Managing allergies with antihistamines, nasal sprays, or allergy avoidance Surgical intervention for structural abnormalities like deviated septum correction Removal of enlarged adenoids or tonsils in children to improve airway patency Nasal decongestants or saline sprays to reduce congestion Myofunctional therapy to improve oral and facial muscle function Using humidifiers to prevent nasal dryness Treating sinus infections with prescribed medications Addressing sleep apnea with CPAP therapy or other interventions
