Revision endoscopic sinonasal surgery is often needed for chronic rhinosinusitis. Common causes include polyps and incomplete ethmoidectomy, indicating a need for improved surgical techniques and follow-up to reduce revision rates.
Area of Science:
- Otolaryngology
- Surgical Innovation
Background:
- Endoscopic sinonasal surgery is a primary treatment for chronic rhinosinusitis refractory to medical management.
- While successful, 2.5%-24% of patients require revision endoscopic sinonasal surgery (RESS).
Purpose of the Study:
- To analyze the clinical, anatomical, radiological, and histological features of patients undergoing RESS.
- To identify common causes and characteristics of revision cases.
Main Methods:
- Retrospective review of patient data from 2012-2014.
- Analysis of clinical, anatomical, radiological, and histopathological findings in RESS patients.
Main Results:
- 9% of 299 sinonasal surgeries were RESS.
- Chronic polypoid rhinosinusitis was the most frequent diagnosis.
- Stenotic antrostomy (81.5%) and incomplete ethmoidectomy (59.3%) were primary findings.
- Persistent anterior ethmoidal cells noted in 70.4% on radiology.
Conclusions:
- Polyps, stenotic antrostomy, and incomplete ethmoidectomy are key reasons for RESS.
- Patients often experience long intervals without follow-up between surgeries.
- Further research is needed to develop strategies for reducing RESS.
