Abstract:

Objective: Conventional apicoectomy methods are often challenging due to restricted visualization and limited access, which can hinder surgical precision and reduce the likelihood of success. The endoscopic-assisted approach addresses these limitations by enhancing visualization and improving surgical accuracy, particularly in complex anatomical regions. This study aims to assess the clinical and radiographic outcomes of patients diagnosed with odontogenic maxillary sinusitis who underwent simultaneous endoscopic apicoectomy and maxillary sinus surgery, highlighting the clinical utility of this combined approach.
Materials and

Methods: The study included 20 patients treated at the Department of Oral and Maxillofacial Surgery, Seoul National University Dental Hospital, between 2014 and 2024. Data were collected retrospectively from patient medical records. Demographic information such as age, gender, systemic disease history, and presenting symptoms was recorded. Clinical data included the identification of the causative tooth, status of the ostiomeatal unit (OMU) obstruction, and recurrence of symptoms during follow-up.

Radiographic assessments were performed at the following time points: preoperative, 3 months postoperative, 6 months postoperative, and 1 year postoperative. Grayscale density and two-dimensional area changes of the maxillary sinus in the Waters’ view were compared to assess air-fluid levels, opacification, and mucosal thickening.
Results Statistical analysis was performed using SPSS Program ver. 29 (SPSS Inc., Chicago, IL, USA) with the Wilcoxon signed-rank test. A P value of less than .05 was considered statistically significant. The analysis revealed significant improvements in maxillary sinus opacification and mucosal thickening over the follow-up period, suggesting favorable postoperative outcomes.

Conclusion: Simultaneous endoscopic apicoectomy and maxillary sinus surgery demonstrated positive clinical and radiographic outcomes in patients with odontogenic maxillary sinusitis. This combined approach may offer an effective treatment option for managing odontogenic maxillary sinusitis, particularly in cases where conventional apicoectomy is challenging, potentially preserving the affected tooth without the need for extraction.
