    Impact of Tumor Resection Volume on Visual Outcomes and the Need for Secondary Surgery Following Transsphenoidal Surgery in Suprasellar Extended Non-Functionial Pituitary Adenomas
    (Turkish Neurosurgical Society, 2024) Batur, Abdussamet; Bozkurt, Mustafa Alper; Gezer, Burak; Karabagli, Hakan; Koktekır, Ender; Sahinoglu, Mert; Gündoğdu, Derya Karaoğlu
    AIM: To investigate the surgical outcomes in patients with nonfunctional pituitary adenomas (NFPAs) exhibiting visual field defects (VFDs) in order to ascertain the impact of the volume of adenoma excised during surgery on recurrence rates and improvements in VFDs. MATERIAL and METHODS: From a cohort of 150 individuals diagnosed with NFPAs and exhibiting suprasellar extensions accompanied by VFDs, we selected 114 patients who fulfilled the inclusion criteria for further analysis after a comprehensive retrospective review. All selected patients underwent pituitary magnetic resonance imaging (MRI) examinations, and volumetric measurements were conducted on T1 contrast sequences using the Syngo.via software. Measurements were derived from MRI scans taken 24 h preoperatively, 24 h postoperatively, at 3 months, and at the end of the first year postsurgery. Volumetric values were compared between patients who underwent subsequent surgeries due to recurrence and those who did not. Similarly, the variables were evaluated in patients experiencing an improvement in VFD, those whose VFD remained stable, and those experiencing a deterioration in VFD. RESULTS: The recurrence rate was 19.3%. Among patients who underwent a second surgery due to recurrence, the presurgical adenoma volume, the adenoma volume removed based on the 24-h postoperative MRI, and the volumes recorded in the 3-month and 1-year postoperative imaging were significantly greater than those in patients who did not require a second surgery. Remarkable improvements were identified in 84.2% of patients with VFD complaints and 62.5% of those with visual acuity complaints. CONCLUSION: Adenoma volume measurements exerted a significant impact on recovery from VFDs and the need for a second surgery. Although the choice of surgical methodology does not definitively affect outcomes, an in-depth evaluation of variations in adenoma volume can provide valuable prognostic insights.

    Anatomical Examination of Intraparotid Lymph Nodes in Various Tumors of Parotid Gland Using Magnetic Resonance Imaging
    (Elsevier Science Inc, 2025) Selcuk, Mehmet; Dogan, Nadire Unver; Onal, Merih; Batur, Abdussamet; Karabulut, Ahmet Kagan; Fazliogullari, Zeliha
    Objective. This retrospective study aimed to anatomically compare the morphometric measurements of intraparotid lymph nodes across different parotid gland tumors and a control group. Study Design. The study used retrospective images of patients admitted to the Department of Otorhinolaryngology over the past 10 years from the Radiology Department archive at Sel,cuk University Medical Faculty Hospital. A total of 160 individuals were included in our study.Long-axis diameter (LAD) and short-axis diameter (SAD) were measured in axial section on magnetic resonance images. Results. In all patients, the mean SAD and LAD were significantly higher on the lesion (+) side compared to the lesion (-) side (P < .05). The mean SAD and LAD were significantly larger on the lesion (+) side compared to the control group (P < .05). Conclusions. In our findings, if the SAD exceeded 3.51 mm and the LAD exceeded 4.85 mm in the control group, it can be considered suspicious in terms of lymph node abnormality, potential pathologic evaluation, and indications for further examination.
