This paper presents anatomy and topography of the inconstant osseous bridges that may occur in the sella turcica region. The interclinoid bridge and the caroticoclinoid bridge can be formed in consequence of abnormal ossification of the dural folds or disturbances in development of the sphenoid bone. Their presence may be of clinical importance because of potential influence on the neurovascular structures passing in the vicinity of the clinoid processes of the sphenoid bone.

Sellar and perisellar meningiomas: effects on pituitary function in a Spanish cohort observational study.
Pituitary
December 2024
Department of Endocrinology and Nutrition, Hospital Universitario de Puerta de Hierro Majadahonda, Madrid, Spain.
Purpose: Studies focused on the effects of sellar and/or perisellar (S/PS) meningiomas on pituitary function are scarce. The primary objective of the present study was to determinate the effects that S/PS meningiomas and their treatments have on pituitary function. Also, we described the clinical characteristics and therapeutic outcomes of the cohort of adult Spanish patients.

Introduction: Tumorous growths in the sellar region pose significant clinical challenges due to their proximity to critical visual structures such as the optic chiasm and optic nerves. Given their proximity to the optic system, these tumors are often diagnosed due to a progressive decrease in visual acuity. Thus, surgical intervention is crucial to prevent irreversible damage, as timely decompression can halt the progression of edema and subsequent optic atrophy.

Objectives: To determine the incidence of postoperative cerebrospinal fluid (CSF) leaks after endoscopic endonasal transsphenoidal surgery (EETS) for pituitary adenomas without sellar floor reconstruction (SFR).
Methods: This retrospective observational study was conducted at Department of Neurosurgery, Punjab Institute of Neurosciences (PINS), Lahore, Pakistan from January, 2018 to December, 2022. It is a non-probability based consecutive case series.
Clinical Characteristics, and Prevalence of Hepatic and Bone Mineral Density Abnormalities in Patients With Sheehan Syndrome: Data From a Tertiary Care Center.

Department of Endocrinology, Post Graduate Institute of Medical Education and Research (PGIMER), Chandigarh, India.
Objective: Sheehan syndrome (SS), or postpartum pituitary necrosis, occurs due to reduced vascular supply to pituitary gland after postpartum hemorrhage, often linked to coagulation abnormalities, and pituitary antibodies. A smaller sella turcica volume is a risk factor for SS, consequent to compressive effects on the pituitary stalk. Hypopituitarism in SS increases the risk of metabolic liver and bone diseases.

The orientation of the head during the acquisition of cone beam computed tomography (CBCT) is crucial for accurate cephalometric measurements. However, involuntary head movements during the scan can result in misaligned images. This study presents a method to correct the natural head position (NHP) in CBCT skull images after acquisition.
