Summary
A modified inferior maxillary antrostomy (IMA) provides a temporary intraoperative window for challenging maxillary sinus lesions. This technique offers improved access to difficult areas with no significant postoperative complications, aiding in treating complex sinus diseases.
Area of Science:
- Otolaryngology
- Endoscopic Sinus Surgery
- Maxillary Sinus Anatomy
Background:
- Endoscopic middle meatal antrostomy (MMA) is standard for maxillary sinus pathology.
- MMA has limitations in accessing specific sinus regions like alveolar and zygomatic recesses.
- Combined approaches are often needed for complete sinus exposure.
Purpose of the Study:
- To present a modified inferior maxillary antrostomy (IMA) technique.
- To evaluate the outcomes of this modified approach for maxillary sinus disease.
- To assess postoperative complications and flap integrity.
Main Methods:
- Retrospective chart review of 20 patients undergoing submucosal temporary inferior maxillary antrostomy (STIMA).
- Data collected included demographics, diagnosis, STIMA indication, disease outcome, complications, and flap condition.
- Study period: January 2020 to July 2023.
Main Results:
- 18 patients met inclusion criteria; mean age 33, predominantly male (13/18).
- Chronic sinusitis was the most common diagnosis; 4 patients had polypoidal mucosa.
- No neural, orbital, lacrimal, or dental complications; 2 patients had minor flap defects.
Conclusions:
- The modified STIMA technique shows promise for accessing challenging maxillary sinus lesions.
- It provides a temporary intraoperative window with minimal adverse effects.
- This approach is valuable for complex cases requiring combined surgical strategies.
