arrest. Accurate detection of the mandibular canal is a difficult process despite cutting-edge radiographic methods. The present study analyses whether mandibular canal roof visibility is comparable to panoramic radiography (PR) and cone-beam computed tomography (CBCT) and, further, examines whether the visibility in PR and CBCT is dependent on cortical bone thickness in the mandible. This study was conducted on a group of 343 selected patients. It incorporated anonymised data on 343 patients in which a CBCT and PR were available. The first stage examines whether the mandibular canal roof visibility is comparable to PR and CBCT. In the second stage, measurements of cortical bone thickness showed buccal and lingual in the P2, M1, M2 and M3 teeth areas, both to the left and right of the mandible in CBCT images. Statistical analysis was supported by statistical software (IBM SPSS 25; Armonk, NY, USA). The mean age of the patients was 58.8 years with an almost equal gender distribution. When performing a McNemar test on the P2, M1, M2 and M3 on both the left and right jaws, the difference between the two image modalities, with regard to the visibility of the canal roof, was found to be significant (McNemar test, p < 0.001). Statistically (U test, p≥0.05), it follows that the thickness of the cortical bone of the mandible exerts no influence on the visibility of the roof of canalis mandibulae in PR and CBCT images. We conclude that the visibility of the mandibular canal in PR and CBCT rays is not identical, and that the thickness of the cortical bone in the mandible does not represent a factor affecting the visibility of the roof of the mandibular canal.

The role of transsphenoidal surgery in the recovery of preexisting hormone dysfunction from pituitary tumors remains controversial. This study aimed to investigate the incidence of hormone dysfunction among asymptomatic non-functioning pituitary adenomas and their recovery following endoscopic transsphenoidal surgery. Eligibility criteria included age under 80 years, presence of a non-functioning pituitary adenoma compressing the normal gland resulting in deviation of the stalk, absence of visual symptoms, and availability for regular follow-up using MRI and pre- and post-operative endocrinological assessments. 182 patients with silent non-functioning pituitary adenomas were included in this study between March 2014 and December 2018. All patients underwent endoscopic transsphenoidal surgery and complete hormonal evaluation, with basal hormone assays and a combined pituitary function test before and after surgery until the end of last follow-up. Preoperative assessment of hormonal function revealed that with silent hormone dysfunction are often overlooked by clinicians and patients. We suggest that even silent hormone dysfunction in patients with non-functioning pituitary adenomas can be improved with effective surgical decompression and these tumors may be potential indications of endoscopic transsphenoidal surgery.

This study aimed to improve the understanding of the role of adjuvant radiotherapy (AR) after subtotal resection (STR) of World Health Organization (WHO) grade I meningiomas.
