Summary
Endonasal and external approaches to the frontal sinus offer successful surgical treatment for sinusitis, trauma, and tumors. Success rates vary by technique, with endonasal methods showing high efficacy in specific procedures.
Area of Science:
- Otolaryngology
- Neurosurgery
- Surgical Oncology
Background:
- Frontal sinus surgery is crucial for managing inflammatory sinus disease, trauma, and tumors.
- Endonasal and external approaches offer distinct advantages for frontal sinus treatment.
Purpose of the Study:
- To validate endonasal surgical approaches for frontal sinus conditions.
- To define the role of external approaches in frontal sinus surgery.
- To assess the efficacy of different frontal sinusotomy techniques.
Main Methods:
- Retrospective review of 1286 patients undergoing endonasal or external frontal sinusotomy.
- Analysis of data from four university teaching programs spanning from 1977.
- Inclusion of prior author reports and previously unreported patient series.
Main Results:
- Successful outcomes reported for endonasal frontal sinusotomy types I, II, and III, ranging from 85.2% to 99.3%.
- External frontal sinusotomy (osteoplastic) achieved a success rate of 96.4% (187/194 patients).
- Postoperative success was measured by clinical symptoms, imaging, and reoperation rates.
Conclusions:
- A stepwise surgical approach to frontal sinus disease yields high success rates (79%–97.8%).
- Endonasal techniques are effective for specific indications, while osteoplastic frontal sinusotomy remains a gold standard for external access.
- Technique details, essential points, and author variations are discussed for optimal patient outcomes.
