Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Different endoscopic techniques have been introduced for performing frontal sinusotomy. Draf categorized them into four techniques (Draf I, Draf IIa, Draf IIb, Draf III). Draf II procedures widen the frontal sinus outflow tract from the lamina papyracea laterally to the middle turbinate (Draf IIa) or the nasal septum medially (Draf IIb).
The thickness of the nasofrontal beak, and a limited anterior-posterior dimension of the frontal recess, make the Draf IIa frontal sinus surgery with angled endoscopy and instrumentation visually diffcult and requires skilled dexterity.
The direct access or Carolyn's window approach to the frontal recess replicates Draf's technique via the endoscopic approach. The approach utilizes only the 0° endoscope. In this approach, the entire frontal process of the maxilla, agger nasi and nasal process of the frontal bone, is removed with a high-speed drill.The goal of the approach is to visualize all walls of the frontal sinus via a ° endoscope. This postoperative view predicts better irrigation access and drainage of the frontal sinuses.
