Introduction Postoperative maxillary mucocele (POMM) is a late postoperative complication of radical maxillary sinus surgery, usually performed by Caldwell-Luc surgery. Around 20% of POMMs occur after radical maxillary surgery and [...]
Objective: This study aimed to evaluate the efficacy of endoscopic marsupialization in patients with postoperative maxillary mucocele having orbital floor defects and to assess the demands for the direct orbital approach for orbital reconstruction. Methods: The study involved a retrospective review of 27 cases of postoperative maxillary mucocele with orbital floor defect. Medical records were reviewed for aspects pertaining to the clinical symptoms, surgical approach, and surgery outcomes. The maximum diameter of the involved orbital floor was calculated from images obtained by paranasal sinus computed tomography. Results: The most common symptom was increased maxillary cheek pressure. The maximum diameter of the involved orbital floor as assessed by paranasal sinus computed tomography ranged from 0.54 to 3.1 cm (mean, 1.50 [+ or -] 0.71 cm), and the area of the involved orbit ranged from 0.27 to 6.02 [cm.sup.2] (mean, 2.35 [+ or -] 1.86 [cm.sup.2]). Endoscopic marsupialization without orbital reconstruction was performed for all patients exclusively. Following the surgery, no patient exhibited recurrence of clinical symptoms or required revision surgery. Conclusion: Endoscopic marsupialization without orbital floor reconstruction may be the preferred treatment for postoperative maxillary mucocele with orbital floor defect except those where the postoperative maxillary mucocele is anterolaterally formed or multicystic.
