Summary
Transnasal endoscopic surgery effectively treats subperiosteal orbital abscesses secondary to acute rhinosinusitis. Wide exposure and orbital manipulation ensure complete abscess drainage, a critical step for successful outcomes.
Area of Science:
- Otolaryngology
- Ophthalmology
- Surgical Endoscopy
Background:
- Subperiosteal orbital abscess (SPOA) is a serious complication of acute rhinosinusitis.
- Transnasal endoscopic management has gained popularity for treating these orbital complications.
Purpose of the Study:
- To describe the transnasal endoscopic approach for SPOA and orbital abscess.
- To present efficacy criteria for ensuring complete abscess drainage.
Main Methods:
- Retrospective review of 22 patients undergoing surgery between 1993 and 2007.
- Surgical technique involved wide periorbital exposure and bidirectional orbital manipulation.
- Orbital pressure reduction via palpation was used as an efficacy criterion.
Main Results:
- Nineteen patients had SPOA, and three had orbital abscesses.
- The described technique facilitated identification and successful drainage of abscesses.
- Immediate reduction in palpable orbital pressure indicated adequate drainage.
Conclusions:
- Transnasal endoscopic approach is effective for SPOA and orbital abscess.
- Wide periorbital exposure and bidirectional orbital manipulation enhance the procedure.
- Monitoring orbital pressure provides a reliable efficacy criterion for drainage assessment.
