Clinical Causes: Structural weakness in the nasal cartilage or tissues Previous nasal trauma or injury damaging the nasal framework Aging processes leading to loss of tissue elasticity Nasal surgeries or procedures that alter nasal support structures Congenital weakness of nasal cartilages Chronic inflammation or infections causing tissue degradation

Key Symptoms: Nasal congestion, especially during inhalation Feeling of obstruction or blockage in the nose Visible nose bulb or collapse when breathing in Difficulty breathing through one or both nostrils Tinnitus or a feeling of pressure in the face Nasal deformity or asymmetry during inspiration

Diagnosis Path: Diagnosis involves a clinical examination, including visual inspection and assessment of nasal airflow. Techniques such as nasal endoscopy might be used to observe the dynamic collapse of the nasal sidewall. In some cases, imaging studies or nasal airflow measurements can aid in confirming the diagnosis. The clinician will evaluate the patient’s history, breathing patterns, and the mechanical stability of nasal structures during the examination.

Treatment Protocols: Management of external nasal valve collapse often requires a tailored approach depending on the severity and underlying cause. Common interventions include: - **Nasal valve support procedures:** Techniques like nasal valve dilation, suturing, or grafting to reinforce the nasal sidewall. - **Surgical correction:** Rhinoplasty or other surgical procedures to restore or improve nasal framework support. - **Non-surgical methods:** Use of nasal strips or external devices to temporarily open the nasal passages. - **Addressing underlying causes:** Treating inflammation, managing trauma, or correcting structural deformities. Patients are encouraged to consult with a qualified ENT specialist or plastic surgeon for a comprehensive evaluation and personalized treatment plan.
