Summary
Endoscopic frontal sinusotomy offers durable patency for chronic rhinosinusitis patients. Long-term results show high success rates, regardless of eosinophilic inflammation presence.
Area of Science:
- Otolaryngology
- Rhinology
- Surgical Outcomes
Background:
- The frontal recess is a critical pathway for frontal sinus drainage, often obstructed in chronic rhinosinusitis.
- Eosinophilic inflammation is a recognized factor contributing to chronic rhinosinusitis.
- Mechanical obstruction of the frontal recess is a primary cause of chronic frontal sinusitis.
Purpose of the Study:
- To assess the long-term frontal sinus patency following endoscopic frontal sinusotomy.
- To investigate the impact of eosinophilic inflammation on frontal sinus patency after surgery.
Main Methods:
- Retrospective review of patients undergoing endoscopic frontal sinusotomy (1999-2000).
- Symptom assessment using the Sino-Nasal Outcome Test (SNOT-20).
- Objective evaluation of frontal sinus patency via archived endoscopic photography.
Main Results:
- 161 patients (294 frontal sinuses) with an average follow-up of 45.9 months.
- Overall frontal ostium patency rate of 88.0% was achieved.
- Patency rates were 90% for non-eosinophilic CRS and 85% for eosinophilic CRS (ECRS).
Conclusions:
- Endoscopic frontal sinusotomy provides high-quality, durable frontal ostium patency.
- No significant difference in long-term patency was observed between ECRS and non-ECRS patients.
- Surgical outcomes are favorable for long-term frontal sinus patency.
