Frontal sinus and recess osteomas: an endonasal endoscopic approach
B-ENT
|August 6, 2014
Summary
Endoscopic endonasal surgery safely removes frontal sinus osteomas, significantly reducing frontal pain. However, extensive tumors near the orbital roof may require an external approach.
Area of Science:
- Otolaryngology
- Neurosurgery
- Endoscopic Surgery
Background:
- Increasing use of endonasal endoscopic approaches for frontal sinus and recess osteomas.
- Need for minimally invasive techniques to treat these tumors.
Purpose of the Study:
- To describe the endoscopic endonasal treatment of frontal sinus osteomas.
- To evaluate the safety and efficacy of this approach without external surgery.
Main Methods:
- Retrospective analysis of 29 patients undergoing endoscopic osteoma resection over 5 years.
- Classification of osteomas using the Chiu and Kennedy grading system.
- Assessment of pain intensity using an 11-point scale.
Main Results:
- Endoscopic resection was performed on 29 patients with varying osteoma types (I-IV).
- Frontal pain was the primary surgical indication, with significant post-operative pain reduction (7.5 to 3.3).
- Incomplete removal occurred in 3 patients; one had a successful reoperation, while two required consideration of external approaches due to tumor location.
Conclusions:
- Exclusively transnasal endoscopic resection of frontal sinus osteomas is a safe procedure.
- The endoscopic approach may be insufficient for tumors with narrow frontal ostia or extensive orbital roof/midorbital involvement.
- An auxiliary external approach might be necessary in complex cases.
