Indications for Turbinectomy
Turbinectomy is indicated for patients with allergic rhinitis who have nasal airway obstruction and enlarged inferior turbinates that have failed medical management. 1
Primary Indications
- Nasal airway obstruction due to turbinate hypertrophy that has not responded to adequate medical therapy 1, 2
- Approximately 20% of the population has chronic nasal obstruction caused by turbinate hypertrophy requiring surgical intervention when medical management fails 2, 3
- Marked turbinate hypertrophy affecting quality of life despite appropriate medical management, including intranasal steroids 3
Types of Turbinate Hypertrophy Requiring Intervention
- Bony hypertrophy of the inferior turbinate requiring surgical reduction 1
- Mucosal hypertrophy of the inferior turbinate that has failed to respond to medical therapy 1
- Combined bony and mucosal hypertrophy causing significant nasal obstruction 2
Failed Medical Management
- Inadequate response to intranasal corticosteroids 3
- Failure of antihistamines in allergic rhinitis cases 1
- Unsuccessful treatment with saline irrigations 4
- Lack of response to other conservative measures such as steroid shots or oral steroids 2
Clinical Findings Supporting Turbinectomy
- Physical examination showing significant turbinate hypertrophy 2
- CT imaging confirming turbinate hypertrophy 2
- Documented nasal obstruction with NOSE questionnaire scores of 30 or higher 5
- Grade 4 inferior turbinates and/or advanced middle concha bullosa 5
Expected Benefits of Turbinectomy
- Improved nasal breathing and airflow 1
- Enhanced quality of life 1, 5
- Improved medication delivery for intranasal treatments 1
- Reduced medication use 1
- Better sleep quality 1
- Potential improvement in olfactory function 5
- Possible reduction in headache frequency and severity 5
Contraindications and Cautions
- Patients who are not surgical candidates due to medical comorbidities 1
- Risk of atrophic rhinitis, especially with more aggressive turbinate resection 1
- Normal-appearing turbinates on examination 4
- Patients who have not attempted adequate medical management (minimum 4 weeks) 4
Surgical Approach Selection
The choice of turbinate reduction technique should be based on the nature and extent of turbinate hypertrophy:
- For predominantly bony hypertrophy: submucosal resection, turbinoplasty, or turbinectomy 1
- For predominantly mucosal hypertrophy: surface mucosa procedures like electrocautery or laser vaporization 1
- For combined hypertrophy: submucosal resection with outfracture has shown the most effectiveness with fewest complications 1
Common Pitfalls to Avoid
- Performing turbinate surgery when turbinates appear normal on examination 4
- Excessive tissue removal leading to empty nose syndrome 5
- Failure to address the underlying cause of turbinate hypertrophy (e.g., allergic rhinitis) 6
- Performing total inferior turbinectomy when partial procedures may suffice 7
Evidence on Specific Techniques
- One-third turbinate resection appears to provide better airflow improvement than front-end surgery while preserving more tissue than total turbinate resection 7
- Partial turbinectomy of middle and inferior turbinates during septorhinoplasty can effectively alleviate symptoms while minimizing risks when proper technique is used 5
- Submucosal resection with outfracture has been identified as the most effective surgical therapy with the fewest complications 1
Turbinectomy should be considered only after thorough evaluation of the patient's symptoms, physical findings, and response to medical therapy, with the surgical approach tailored to address the specific anatomical issues causing obstruction.
