Trans-Sphenoid Approach to the Sella Turcica
The sublabial trans-sphenoid approach to the sella turcica is a straight path from the gingivolabial sulcus (the groove between the upper lip and the gum) to the face of the sphenoid sinus. A small incision is made in the gingivolabial sulcus and the nasal septum is moved to the side. The anterior wall of the sphenoid sinus is opened. The sella turcica is also opened and the tumor is removed. The septum is finally replaced in the midline and the incision is closed with absorbable sutures.

The sphenoid sinus is a bony cavity lined with mucosa and filled with air. It is located behind the roof of the nose.
The sella turcica (Turkish saddle) is a spherical bony cavity located in the roof of the sphenoid sinus. It contains the pituitary gland. Whenever there is a tumor in the pituitary gland, the sella turcica enlarges and protrudes into the sphenoid sinus.
