Abstract
Summary
Endoscopic sphenoid sinus surgery can be challenging due to
its close relation to vital anatomical structures such as the optic
nerve, ICA, skull base, orbit. Even minimal damage to the
surrounding structures during FESS can lead to serious
complications such as blindness or massive bleeding.
The sphenoid sinus natural ostium provides a natural and
safe access for endoscopic management of the sphenoid sinus
lesions. It is not always easy to locate the ostium during the
endoscopic approach. The present study was designed to assess the
value of the superior turbinate as a constant and reliable anatomic
landmark for the location of the sphenoid sinus ostium and the utility
of the surgical techniques for safe endoscopic sphenoidotomy in
relation to position of the superior turbinate attachment to the
sphenoid face.
A prospective study of 40 patients who underwent
endoscopic management of sphenoid sinusitis resistant to medical
treatment. There were 15 males and 25 females ranging from 11-60
years old. Patients were divided into two main groups:
group A: included patients with isolated sphenoid sinusitis (10
patients with 12 sides).
group B: included patients with sphenoid sinusitis associated with
other sinuses affection (30 patients with 58 sides).
