Abstract:
Objective:To evaluate the early efficacy and safety of the exclusively transnasal endoscopic approach and the combined transconjunctival-endoscopic approach in the resection of benign orbital apex lesions.Methods:A retrospective analysis was conducted on 51 patients who underwent transnasal endoscopic resection of benign lesions in the orbital apex at Peking University Third Hospital from May 2021 to December 2024. The study population was composed of 17 males and 34 females, with the age of (39.4±12.4) years (range: 4 to 65 years). Pathology diagnoses were identified as orbital cavernous hemangioma (OCH, n=38), schwannoma ( n=8), solitary fibrous tumor ( n=1), mucocele ( n=1), optic nerve sheath meningioma ( n=1), pseudotumor ( n=1), and organized hematoma ( n=1). Two surgical approaches were compared as the exclusively transnasal endoscopic resection ( n=27) and the combined transconjunctival-endoscopic approach (combined approach, n=24). Preoperative and postoperative evaluations were conducted for the best corrected visual acuity (BCVA), visual field, intraocular pressure (IOP), and exophthalmos before and after surgery. Demographic characteristics, tumor features, and postoperative complications were analyzed between the two surgical groups. Differences in Orbital Resection by Intranasal Technique (ORBIT) stage between the two surgical approaches were analyzed. SPSS 27.0 software was used for statistical analysis. Results:Among the 51 patients, 3 schwannomas underwent intracapsular resection (1 via exclusively transnasal endoscopic approach, and 2 via combined approach), and the remaining 48 patients underwent complete tumor resection. Significant postoperative improvements were observed in BCVA, visual field, IOP and exophthalmos ( t value was 2.96, 4.34, 4.85, and 4.63, respectively, all P<0.05). The combined approach required longer operative time but showed comparable intraoperative blood loss. Tumors resected via the combined approach were larger in volume, though not statistically significant. Postoperative complications (e.g., diplopia, mydriasis) were more frequent in the combined approach group but resolved within a short-term period. There was no significant difference in ORBIT stage between the two groups ( P=0.178). Conclusions:Both exclusively transnasal and combined transconjunctival-endoscopic approaches prove safe and effective for benign orbital apex lesions resection. The combined approach ensures complete tumor removal.
