Introduction: We aimed to analyze the difficulties and complications experienced while as a beginner in endoscopic transnasal transsphenoidal approach for pituitary adenomas.
Materials And Methods: We retrospectively analyzed 83 cases done from June 2016 to August 2019. Navigation-guided endoscopic transnasal transsphenoidal approach was used in all the cases.
Results: Gross total tumor removal was achieved in 55 (66.26%) patients. We found that gross total resection rate was inversely proportional to Knosp grading, and the extent of resection was found to have a statistically significant correlation with grade of tumor ( < 0.05). Surgery-related complications were present in 33 of our patients. Nasal complications occurred in six patients: three epistaxis (3.6%) and two hyposmia (2.4%) and one case of septal hematoma (1.2%). Postoperative cerebrospinal fluid leak occurred in six (7.2%) cases, two (2.4%) cases had sinusitis, while two (2.4%) cases had meningitis. There was a very rare case of subarachnoid hemorrhage and one case had sellar hematoma. Endocrinologic complications occurred in 15 (18.07%) patients: anterior pituitary deficiency in five (6.02%) patients, transient diabetes insipidus (DI) in nine (10.84%) patients, and permanent DI in one (1.2%) patient. There was no vascular injury or mortality noted in our study.
Conclusion: Endoscopic approach is an effective modality for pituitary surgery; with patience, learning lessons from your own mistakes and by adopting right technique, learning curve can be flattened significantly.

Unlabelled: Intracranial complications in inflammatory diseases of the ear and nose are currently not frequent, but their lethality remains high. The choice of optimal, safe and effective access in surgical treatment of purulent-inflammatory intracranial complications remains a subject of discussions and is based on an individual approach, depends on the volume, localization and clinical condition of the patient.

Background: Transnasal endoscopic decompression of the optic nerve is increasingly gaining acceptance among ear, nose, and throat (ENT) surgeons, however neither strict indications for the procedure nor the precise extent of effective decompression have been firmly established to date. This study aimed to determine the distance between endoscopically visible, anatomical structures within the sphenoid sinus and the posterior (i.e.

This study aimed to examine the clinical features and assess the surgical outcomes of traumatic optic neuropathy in pediatric patients. A retrospective analysis was conducted on the clinical data of 15 cases (17 eyes) of traumatic optic neuropathy in pediatric patients aged 1 to 6 years between January 2015 and July 2024. Two of them presented with binocular trauma, resulting in a total of 17 affected eyes.

Background: Cerebrospinal fluid (CSF) leakage frequently complicates endoscopic endonasal transsphenoidal pituitary resections, despite the use of lumbar drains, nasoseptal flaps, or commercial dura sealants. Managing this complication often requires revision surgery and increases the risk of infection. Platelet-rich fibrin (PRF), an affordable autologous biomaterial derived from the patient's blood through short, angulated centrifugation, contains growth factors and leukocytes embedded in a fibrin matrix.

The temporoparietal fascia flap (TPFF) has recently emerged as an option for skull base reconstruction in endoscopic transnasal surgery when vascularized nasal flaps are not available. This study provides a systematic literature review of its use in skull base surgery and describes a novel cohort of patients. PRISMA guidelines were used for the review.
