Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Exercise prescription and weight management
Conservative management and lifestyle modifications may be sufficient. Monitor symptoms.
Septoplasty
Surgical correction of deviated or abnormal nasal septum repositions the septal cartilage and bone to restore normal anatomy. This procedure addresses both functional breathing issues and structural abnormalities.
Nasal saline irrigation
Post-operative or conservative nasal irrigation keeps the nasal passages moist and clear of debris. This supports healing and prevents crusting in cases of septal abnormalities.
Additional treatment options
Topical nasal corticosteroids
Corticosteroid sprays reduce inflammation around the nasal septum, helping manage swelling and discomfort associated with septal abnormalities. They support mucosal healing and symptom control.
medicationSerial clinical examination
For mild septal abnormalities, regular monitoring with periodic nasal endoscopy assesses progression and determines if intervention becomes necessary. This approach avoids unnecessary procedures.
monitoringDecongestant nasal sprays
Short-term use of topical decongestants can temporarily improve airflow through narrowed nasal passages caused by septal deviation. Provides symptomatic relief while planning definitive treatment.
