Septoplasty Guidelines for Deviated Nasal Septum
Indications for Surgery
- Septoplasty is indicated for persistent nasal obstruction that interferes with daily activities, work, or school performance. 1
- Septoplasty is indicated for recurrent sinus infections (≥ 3 episodes per year) despite optimal medical therapy. 2
- Septoplasty is indicated when medical management with topical nasal steroids and decongestants has failed. 3
Pre‑operative Clinical Assessment
- Although ~ 80 % of the general population has an off‑center septum, only ~ 26 % of individuals reporting nasal obstruction have a clinically significant deviation, underscoring the need for careful patient selection. 4
- Anterior septal deviations contribute the majority of nasal airflow resistance and are therefore more clinically significant than posterior deviations. 5
- A trial of topical decongestants can help differentiate mucosal swelling from structural obstruction; lack of symptomatic improvement suggests that structural correction (septoplasty) is likely to be beneficial. 6
- Compensatory turbinate hypertrophy commonly occurs on the side opposite the deviation (or bilaterally with S‑shaped deviations) and should be evaluated pre‑operatively. 4
- Inferior turbinate reduction is frequently performed together with septoplasty, although current evidence does not conclusively demonstrate long‑term added benefit. 4
Surgical Technique Preference
- Septoplasty is the preferred operative approach over submucosal resection because it reshapes or repositions cartilage rather than extensively resecting tissue. 7
- The procedure is tissue‑sparing, which contributes to lower complication rates. 4
- Endoscopic septoplasty is increasingly favored over traditional techniques due to superior visualization, reduced intra‑operative and post‑operative hemorrhage, lower rates of mucosal adhesions and persistent deviation, and shorter operative time. 5
Expected Outcomes and Potential Limitations
- Approximately 77 % of patients report subjective improvement after septoplasty. 4
- Recurrence of septal deviation may occur after surgery, highlighting the importance of thorough pre‑operative planning. 4
- Some patients may continue to experience a disturbed nasal cycle despite successful correction. 4
- Comprehensive evaluation of all contributors to nasal obstruction (e.g., turbinate hypertrophy, mucosal disease) is essential, as addressing the septum alone may not resolve symptoms. 6
Pediatric Considerations
- Septoplasty is generally avoided in children because it can adversely affect nasal growth, particularly of the nasal dorsum. 7
Referral Criteria to Otolaryngology
- Refer patients when anatomic defects obstruct the ostiomeatal complex. 8
- Refer patients with recurrent sinusitis occurring 2–3 times per year despite appropriate treatment. 8
- Refer patients with complications that threaten intracranial or ocular structures (e.g., meningitis, brain abscess, vision loss). 5
- Refer patients with persistent nasal polyps despite optimal medical therapy. 8
Evidence‑Based Management of Deviated Nasal Septum
Medical Therapy (Limited Role)
Isotonic saline irrigation can give modest symptom relief by mechanically clearing mucus and inflammatory mediators, but its benefit for purely structural obstruction is inconsistent; high‑volume nasal douching (≈250 mL twice daily) distributes better to the sinuses than sprays or nebulization, and a treatment duration of 3–7 months may be required to observe any effect 9.
Intranasal corticosteroid sprays provide little improvement in obstruction caused by septal deviation unless there is concurrent mucosal inflammation or turbinate hypertrophy 10.
Topical nasal decongestants have very limited supporting evidence, carry a risk of rebound congestion with long‑term use, and are only useful for a short‑term (≤5–7 days) trial to distinguish mucosal swelling from fixed structural blockage 10, 11.
The EPOS 2020 guideline explicitly recommends against routine use of nasal decongestants in chronic nasal obstruction 10.
Oral antihistamines are not indicated for septal deviation‑related obstruction unless the patient also has allergic rhinitis 11, 12.
Patient Selection for Septoplasty
Although ~80 % of the general population has an off‑center septum, only about 26 % of individuals who report nasal obstruction have a clinically significant deviation; therefore, careful selection is essential 11.
Compensatory turbinate hypertrophy frequently develops on the side opposite the deviation (or bilaterally with S‑shaped deviations) and should be assessed before surgery 11.
Surgical Technique and Outcomes
Septoplasty reshapes, repositions, or recontours the cartilaginous septum rather than performing extensive tissue resection, preserving nasal structure 11.
This tissue‑sparing approach is associated with lower complication rates, notably a reduced risk of septal perforation compared with submucosal resection 11.
Approximately 77 % of patients report subjective improvement after septoplasty 11.
Recurrence of septal deviation can occur after surgery, underscoring the need for thorough pre‑operative planning 11.
