R49.22

Clinical Causes: Nasal obstructions such as enlarged adenoids or tonsils Deviated nasal septum Nasal polyps or tumors Chronic sinus infections or inflammation Cribriform plate abnormalities Previous nasal or sinus surgeries leading to structural changes Allergic rhinitis causing swelling or congestion Congenital abnormalities affecting nasal passages

Key Symptoms: Reduced nasal resonance during speech, resulting in a muffled or dampened sound Difficulty achieving nasal sounds like 'm', 'n', and 'ng' pronounced normally Nasal congestion or blockage sensations Breathing difficulties through the nose A sense of fullness or pressure in the nasal area Altered speech quality affecting communication Potential discomfort or nasal discomfort

Diagnosis Path: Medical history review focusing on nasal and respiratory health Physical examination of nasal passages and throat Nasal endoscopy to visualize blockages or structural abnormalities Imaging studies such as X-rays or CT scans to identify structural issues Speech assessment to analyze resonance and nasal airflow Allergy testing if allergic rhinitis is suspected

Treatment Protocols: Medical management of nasal congestion or allergies with antihistamines, nasal sprays, or decongestants Surgical interventions like septoplasty or adenoidectomy to correct structural abnormalities Removal of nasal polyps or tumors if present Speech therapy aimed at improving resonance and speech production Addressing infections such as sinusitis with appropriate medications Use of nasal dilators or strips to improve airflow
