Among his topics are the surgical field in endoscopic sinus surgery, the anatomy of the frontal recess and frontal sinus with three-dimensional reconstruction, powered endoscopic dacryocystorhinostomy, and carotid artery and major vascular injury during endoscopic surgery.
Frontal sinus mucoceles can sometimes be prevented from closing and reforming by stenting, which to the best of our knowledge has not yet been reported in the maxillary sinus.
Among the PNS most commonly involved was maxillary sinus (35 [70%]) followed by ethmoid sinus (20 [40%]), sphenoid sinus (17 [34%]), and frontal sinus (12 [24%]).
In adults, mucoceles are observed most frequently in the frontal sinus and 90% are unilateral (2).
Classical imaging findings include hypoplasia of one brain hemisphere (hemiatrophy), often with reduced volume of a corresponding cranial fossa, and consecutive thickening of nearby bony structures and enlargement of equilateral paranasal sinuses, the frontal sinus being most often involved [1-3].
Additionally, PROPEL mini is indicated for use following frontal sinus surgery.
Destruction of the frontal sinus and frontal bone with intracranial extension into the frontal lobe was evident.
The plane for CT scanning of paranasal sinuses was kept parallel to inferior orbitomeatal line (Reid's baseline) starting at the level of maxillary alveolus just below the hard palate and to end above the level of frontal sinus.
The opened frontal sinus was sealed, and the supraorbital nerve was preserved as possible.
The frontal sinus presents rostral and caudal compartments that extend to the cornual processes.
