The imperative is finding the balance between optimizing the extent of resection, decompressing critical structures and limiting the morbidity to the patient. The endoscopic endonasal approach is increasingly utilised for the management of craniopharyngioma, offering improved access to the suprasellar region while minimizing morbidity to the optic apparatus and neurovascular structures.

Quality of life measures were reported using the Sinonasal Outcome Test (SNOT-22) and Anterior Skull Base Questionnaire (ASBQ-35).

As expected, day 1 SNOT-22 scores were significantly worse compared to baseline (mean difference –23.8 (95%CI: −41.4 to −6.17, p = 0.004). Based on the minimum clinically important difference (MCID) of 8.9, SNOT-22 scores remained worse at day 1, 3 and 7 before falling below MCID at week 3. This trend continued out to 6 and 12 months post-operatively with further reduction in mean difference to near zero at 12 months post-operatively (mean difference −0.1 (95%CI: −20.6 to 20.3). In the nasal subdomain, there was a significant increase in symptoms at Day 1 (p = 0.034) and 3 (p = 0.001) while no significant difference was found beginning at day 7 (p = 0.099).

The extent of resection (EOR) and complications were correlated with LSA involvement patterns and postoperative reduction in the number of visible LSAs.</div></div><div><h3>Results</h3><div>LSA involvement patterns included “displaced” (28%), “contact” (56%), and “engulfed” (16%) types. Postoperatively, mean LSA count declined from 3.76 to 3.0 (p = 0.007). Reduction occurred in all patients with engulfed LSAs and in 30% with contact type. Giant IGs were more frequent in contact and engulfed patterns (p = 0.008). Tumors with reduced LSAs were more often oligodendroglioma or glioblastoma than grade 2 astrocytoma (p = 0.004). LSA loss was unrelated to surgical approach but correlated with radical resection (p = 0.019) and neurological deficits (p = 0.001).</div></div><div><h3>Conclusion</h3><div>IGs with LSA engulfment should undergo subtotal resection, whereas contact-type lesions require intraoperative judgment regarding EOR. Radical resection in giant IGs with unsafe tumor-LSA relationships, especially in aggressive histologies, increases the risk of permanent deficits. Not all single-LSA injuries result in lasting impairment. Routine preoperative 3D-TOF MRA is recommended for evaluating IG resectability and minimizing ischemic complications.</div></div>","PeriodicalId":15487,"journal":{"name":"Journal of Clinical Neuroscience","volume":"146 ","pages":"Article 111866"},"PeriodicalIF":1.8,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146006771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
