Summary
Functional endoscopic sinus surgery (FES) improved symptoms in 90% of patients with bilateral rhinosinusitis. However, post-operative CT scans showed limited improvement, particularly for the frontal sinuses, suggesting careful follow-up is needed.
Area of Science:
- Otolaryngology
- Surgical Innovation
- Medical Imaging
Background:
- Rhinosinusitis significantly impacts quality of life.
- Functional endoscopic sinus surgery (FES) is a common treatment for chronic rhinosinusitis.
- Objective assessment of surgical outcomes is crucial.
Purpose of the Study:
- To evaluate the efficacy of FES for bilateral rhinosinusitis.
- To correlate patient-reported symptoms with objective radiological findings post-surgery.
- To determine optimal follow-up protocols based on surgical experience.
Main Methods:
- Prospective study of 50 consecutive patients undergoing FES for bilateral rhinosinusitis.
- Pre- and post-operative symptom assessment.
- Computerized tomographic (CT) scans analyzed for sinus status before and after surgery.
Main Results:
- 90% of patients reported symptomatic improvement after FES.
- Post-operative CT scans showed only slight improvement in overall sinus scores.
- Statistically significant improvement was noted in ethmoidal sinuses on CT, while frontal sinuses showed no change.
- Frontal sinus findings remained similar radiologically pre- and post-operatively.
Conclusions:
- FES offers significant symptomatic relief for bilateral rhinosinusitis.
- Radiological outcomes on CT scans may not fully correlate with symptom improvement.
- CT follow-up 4-6 months post-surgery is recommended for less experienced surgeons, while experienced surgeons may rely on clinical and endoscopic follow-up for up to 3 years.
