Although the sphenoid sinuses can be identified in sections of the fetus at 4 months, at birth the sinus remains small and is little more than an evagination of the sphenoethmoid recess. After the 3rd year, invasion of the sphenoid bone is more rapid, and by the age of 7, the sinus has extended posteriorly to the level of the sella turcica. By the age of 12, the sphenoid pneumatization reaches its final form and a size equivalent to the adult, although further enlargement into the basisphenoid may occur in the adult. Agenesis of paranasal sinuses is an uncommon clinical sign and refers mainly to the frontal and secondarily to the maxillary sinuses. Agenesis of sphenoid sinuses is a very rare phenomenon in the literature. We present a 32-year-old male patient with agenesis of sphenoid sinuses that was studied by CT.

: Recent years have been marked by a search for new relationships between malocclusions and the morphological features of the cranial base and upper cervical spine. The aim of this study was to evaluate the relationship between skeletal orthodontic malocclusions and the morphological features of sella turcica bridging (STB) and ponticulus posticus (PP). : The study sample consisted of 300 randomly selected pre-orthodontic treatment patients aged 7-40 years.

In patients with acromegaly, the pleiotropic effects of GH and IGF-1 have been associated with the development of endothelial dysfunction and vascular abnormalities. We present the case of a 45-year-old male diagnosed with acromegaly. Magnetic resonance imaging identified a marked dilatation and medialization of both cavernous internal carotid arteries (ICA), leading to a narrow intercarotid distance, a phenomenon known as "carotid kisses".

Understanding the heterogenicity of unicoronal synostosis - A morphometric analysis of cases compared to controls.

Article Synopsis
- The study investigates the variability in skull and facial deformation in patients with unicoronal synostosis, a condition affecting the shape of the head due to early fusion of the skull bones.
- Researchers analyzed data from 95 patients and 93 controls to identify correlations between different cranial deformities, age, and timing of surgeries, finding significant relationships between skull base and orbital asymmetries.
- The findings suggest that the differences in cranial shape are mainly linked to skull base structure and that certain cranial sutures' fusion could potentially limit the extent of deformity.
Isolated abducens nerve palsy following upper respiratory infection in a patient with ipsilateral chronic sphenoid sinusitis.

The abducens nerve, which is vulnerable because of its complex anatomy at the skull base, is seldom affected by acute or severe sphenoid sinusitis. Notably, abducens nerve palsy following asymptomatic chronic rhinosinusitis (CRS) in a healthy young individual after a mild upper respiratory infection (URI) remains undocumented in the literature. Herein, we report a case of acute unilateral abducens neuropathy in a healthy 35-year-old woman with CRS in the ipsilateral sphenoid sinus, following a mild URI 2 weeks earlier.
