The impact of maxillary dimensions on determining surgical approach of fungal ball in the maxillary sinus.
Scientific Reports 2024 May 5
Endoscopic middle meatal antrostomy (MMA) is commonly used for maxillary sinus (MS) fungal ball removal. For challenging cases involving anterior or inferior recess, an additional inferior meatal approach (IMA) might be needed. We analyzed the differences in MS dimensions on CT scans according to the surgical approach to suggest preoperative variables that could facilitate an additional IMA. CT scans of 281 adult patients who underwent ESS for the MS fungal ball (139 MMA, 62 MMA & IMA) were evaluated for comparative analysis of 8 MS measurements based on the surgical approach. Complete removal was achieved in all cases. Age and sex didn't differ significantly (p > 0.05). The maximum distances between the anterior-posterior walls, the inferior ostium border to the lateral recess, and the ostium to the inferior wall of the MS were statistically greater in the MMA & IMA group compared to the MMA group (p = 0.003, p = 0.005, and p = 0.010, respectively), especially among females. This study underscores the clinical importance of specific measurements-anterior to posterior wall, medial wall to lateral recess, and ostium to inferior wall of the maxillary sinus-for guiding optimal surgical approaches in MS lesions.
