Background:
Patients with single-suture or minor suture craniosynostosis are typically asymptomatic at early presentation; intervention is aimed at reducing the risk of elevated intracranial pressure and associated developmental sequelae. Patients may be symptomatic in cases of major multisuture syndromic synostoses or delayed diagnosis. Clinical presentation in this context may include headaches, papilledema, cognitive delay, or behavioral issues. Cranial nerve palsies are atypical symptoms of intracranial hypertension in this patient population.
Case Description:
An 11-month-old, otherwise healthy girl presented with bilateral severe papilledema and left abducens nerve palsy owing to nonsyndromic near-complete bilateral squamosal suture synostosis with associated incomplete sagittal and right lambdoid synostoses. The patient underwent urgent open cranial expansion, with resolution of her papilledema and improvement in eye position and motility.
Conclusions:
Cranial nerve palsies may be presenting symptoms of intracranial hypertension in patients with craniosynostosis. Multidisciplinary evaluation and treatment is paramount for appropriate management.

01:14Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
01:22Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

Olfactory Nerve (Cranial Nerve I)
The olfactory nerve, or cranial nerve I, is unique as it is purely sensory and dedicated to the sense of smell. This nerve originates in the olfactory epithelium of the...
01:27Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
