“…In this study, our objective was to identify the influence of presurgical radiological tumor size on SNH suggesting that patients with smaller lesions experience fewer symptoms due to lower tumor invasiveness and lesser scope of surgery. While large, invasive pituitary tumor growth has been shown to be a predictor for increased complications and incomplete resection in endoscopic transsphenoidal surgery (11), the influence of tumor morphology on SNH has not been evaluated yet. In addition, the effect of endoscopic transsphenoidal surgery on SNH and quality of life has been examined with diverging results (12)(13)(14).…”

Pituitary adenomas are one of the most common mass lesions of the brain and are associated with a reduced quality of life. While transnasal and transsphenoidal endoscopic approaches are considered to deliver similar recovery rates for sino-nasal health (SNH), the impact of radiological tumor growth patterns on SNH has not been evaluated. In the present study, the influence of radiological tumor growth on SNH was examined before and after endoscopic transsphenoidal tumor resection. Patient data were prospectively collected between August 1, 2016 and August 31, 2022. The Knosp and Hardy classifications were used to dichotomize pituitary adenoma lesions into low- and high-graded lesions. SNH was assessed shortly before surgery and at follow-up examinations 3–6 months after operation using the Sino-Nasal Outcome Test for Neurosurgery (SNOT-NC) questionnaire. Fully completed SNOT-NC questionnaires were collected before and after surgery from a total of 101 patients. Independent t-tests showed significantly higher rates of deterioration after surgery in patients with Knosp low-graded lesions compared with those with high-graded tumors for the SNOT-NC total score P=0.048, nasal discomfort P=0.034, sleep problems P=0.024 and visual impairment P=0.042. Pre- and post-operative comparisons for the Knosp low-graded tumor cohort showed an increase of nasal discomfort (P=0.004), while the Knosp high-graded tumor cohort reported decreased visual impairment (P=0.016) after surgery. Assessing the Hardy classification, increased nasal discomfort was reported in patients with high-graded infrasellar tumors after surgery (P=0.046). Growth characteristics of pituitary adenomas based on Knosp and Hardy classifications may influence SNH. Patients with less invasive lesions were revealed to be more prone to experiencing a decrease in SNH, which went beyond the assumed deterioration of 1–3 months. These findings indicate the importance of detailed information regarding SNH as part of every pre-operative patient briefing.
