A lateral rhinotomy approach to transsphenoidal hypophysectomy

The transsphenoidal approach to the sella turcica is nowadays more often used than the transcranial. The disadvantages of the transantral and transseptal approaches are a narrow and distant operative field and various complications. A fluoroscope often has to be used for orientation. With our lateral rhinotomy technique, no fluoroscope is needed as the whole sphenoid can be inspected. Furthermore, the operative field is wide and closer to the surgeon, few instruments are needed, bleeding is easily controlled, the anterior wall of the sella can be properly sealed, CSF rhinorrhoea prevented and the sphenoidal mucosa restored. The whole operation can be performed within 2 h. Fifty-seven patients were operated upon with good results and few complications.
