A66.5

Clinical Causes: Mycobacterium leprae infection, which is responsible for leprosy Chronic bacterial or fungal infections that invade the nasal and pharyngeal tissues Inadequate treatment of initial infections leading to tissue destruction Environmental factors such as poor sanitation or crowded living conditions that facilitate pathogen spread Immunocompromised states that decrease the body’s ability to control infectious agents

Key Symptoms: Gradual nasal obstruction and congestion Persistent nasal discharge, often purulent or bloody Progressive deformity of the nose, including collapse or collapse of the nasal bridge Ulceration and necrosis of the nasopharyngeal mucosa Pain or tenderness in the affected areas Swelling or enlargement of lymph nodes in the neck Possible facial disfigurement and loss of nasal structure Difficulty breathing, speaking, or swallowing in advanced cases

Diagnosis Path: Thorough medical history assessment focusing on duration and progression of symptoms Physical examination of the nose, throat, and neck regions to identify tissue destruction and deformity Nasal endoscopy to visualize internal structures and mucosal damage Radiological imaging such as X-ray or CT scan for structural assessment Laboratory tests, including tissue biopsies, to identify infectious agents like Mycobacterium leprae Serological tests and microscopy if bacterial or fungal infections are suspected

Treatment Protocols: Antimicrobial therapy tailored to the identified causative organism, such as multidrug therapy in leprosy cases Surgical procedures to remove necrotic tissues and repair deformities Supportive care, including analgesics and nutritional support Rehabilitative therapies like speech and swallowing therapy for functional impairments Strict adherence to infection control and follow-up to prevent relapse or progression
