Nasal Septal Deviation: Causes, Symptoms & Treatment
Nasal septal deviation (curvature/displacement of the quadrangular cartilage + vomer/perpendicular plate) affects ~80% of adults; only symptomatic cases need treatment.
Etiology
- Congenital: birth trauma, developmental asymmetry.
- Acquired: nasal fracture (sports, assault, MVA), iatrogenic (septal surgery).
Symptoms
- Nasal obstruction (unilateral/bilateral, alternating).
- Recurrent sinusitis (impaired drainage).
- Epistaxis (dry, turbulent airflow over spur).
- Facial pain, headache (contact points).
- Sleep-disordered breathing, snoring.
Diagnosis
- Anterior rhinoscopy, nasal endoscopy.
- CT sinus if surgical planning or sinusitis evaluation.
Treatment
- Medical: intranasal corticosteroids (reduce mucosal edema), saline irrigation, decongestants (short-term).
- Surgical (Septoplasty): outpatient, general/local; resect/reposition deviated segments; preserve L-strut (1 cm dorsal/caudal).
- Turbinate reduction often combined.
- Success: >85% symptom improvement.
Rhinoplasty (septorhinoplasty) if external deformity coexistent.
