The stellate type, in which the frontal, parietal, sphenoid
and the temporal bones interconnected to each other (Murphy and Saxena et al.
Transnasal bamboo foreign body lodged in the sphenoid
Advanced imaging methodologies demonstrated that ethmoid involvement is the most common, followed by the sphenoid
and frontal bones.
His ECG was normal, but his MRI scan showed a large left sphenoid
wing hypervascular meningioma.
Tumor extends through the greater wing of the sphenoid
into the infratemporal fossa.
The frontal sinuses are most frequently affected (60-65%), followed by the ethmoid (20-30%), maxillary (10%) and sphenoid
Surgical nuances for the endoscopic endonasal transpterygoid approach to lateral sphenoid
Orbital Computed Tomography (CT) (Figure 1, A) demonstrated inflammatory opacification of the left sphenoid
sinus and unusual bony dehiscence at the proximal optic canal.
The maxillary, ethmoid (divided into anterior and posterior cells) frontal and sphenoid
Magnetic resonance imaging (MRI) revealed a soft tissue mass in the sphenoid
sinus, eroding the basi-sphenoid
and extending into the nasopharynx (Fig.
Most mucoceles occur in the frontal sinus (60%), followed by the ethmoid sinus (30%), the maxillary sinus (10%), and very rarely in the sphenoid
