A 28-year-old male presents to the ENT clinic with a 3-year history of persistent nasal obstruction, worse on the left side. He reports frequent headaches localized to the left frontal region and occasional epistaxis. On anterior rhinoscopy, the nasal septum is markedly deviated to the left, with the deviated portion touching the lateral nasal wall. Nasal endoscopy reveals contact of the septal deviation with the left lateral nasal wall and middle turbinate. CT scan of the paranasal sinuses shows a C-shaped septal deviation with contact point at the level of the middle turbinate. The patient has failed conservative management with nasal steroids and antihistamines for 6 months. What is the most appropriate next step in management?

## Clinical Assessment of Deviated Nasal Septum ### Indications for Surgical Intervention **Key Point:** Septoplasty is indicated when DNS causes symptomatic nasal obstruction that has failed conservative management for an adequate trial period (typically 3–6 months). ### Why Septoplasty is Correct Here This patient meets all criteria for surgical correction: 1. **Symptomatic obstruction** — persistent nasal obstruction for 3 years 2. **Anatomical correlation** — endoscopic and radiological confirmation of contact point between deviated septum and lateral nasal wall/middle turbinate 3. **Failed conservative therapy** — 6 months of topical steroids and antihistamines without relief 4. **Functional impact** — associated headaches and epistaxis **High-Yield:** The contact point between the deviated septum and the lateral nasal wall or turbinate is the key anatomical finding that correlates symptoms with structural pathology. Absence of a contact point suggests the deviation is incidental and unlikely to benefit from surgery. ### Surgical Technique Septoplasty corrects the deviation by: - Elevation of mucoperichondrium and mucoperiosteum - Removal or repositioning of deviated cartilage and bone - Restoration of midline position - Preservation of structural support **Clinical Pearl:** Always assess for concurrent pathology (chronic rhinosinusitis, allergic rhinitis) during preoperative evaluation; these may require concurrent FESS or medical optimization. ### Why Other Options Are Suboptimal FESS alone addresses sinusitis but does NOT correct the mechanical obstruction caused by septal deviation. Continued observation or further medical trials are inappropriate after 6 months of failed therapy with clear anatomical correlation.
