Tuberculum sellae meningiomas are usually removed using various transcranial approaches. The extended transsphenoidal approach also indicates for some lesions around the sella turcica. The author primarily approaches supradiaphragmatic tumors through the tuberculum sellae using the extended transsphenoidal approach, termed the “transsphenoidal-transtuberculum sellae approach” even for the tuber...

background petro-clival, clival and spheno-petro-clival tumours are still a neurosurgical challenge. usually, the classical skull base transpetrous approaches are employed, although they are burdened by an important rate of morbidity, and a very low rate of radical removal is reported. conclusions anterior transoral and transsphenoidal approaches are indicated for clival and spheno-petro-clival...

Although there are various operative approaches for clival tumors, a transsphenoidal approach is one of choices when the main tumor extention is in an anterior-posterior direction with a slight lateral extension. However, this approach sometimes provides only narrow and deep operative field. Recently, endoscopic transnasal transsphenoidal approach is quite an effective approach for clival tumor...

Transsphenoidal microsurgery has been the standard approach to sellar lesions since the repopularization of the technique with modifications by Dott, Guiot, and Hardy. The endonasal transseptal transsphenoidal approach, as introduced by Hirsch, is still commonly used by pituitary surgeons to remove lesions of the sellar and parasellar region. One disadvantage of this approach is that the submuc...

Transsphenoidal encephaloceles are rare and the transsellar variety is the least common. We present a 1-year-old male patient with transsellar transsphenoidal encephalocele which herniated into the oral cavity through the congenital split palate. The patient was operated on using a combined transcranial and transpalatal approach without mortality or permanent morbidity. Clinical findings, imagi...

Background and Aim: EETA (Endoscopic Endonasal Transsphenoidal Approach) is a preferred choice for pituitary tumors. offers minimal invasiveness, fewer complications, better outcomes than the sublabial or transseptal microscopic approach. has three approaches: mononostril endoscopic transsphenoidal approach, binostril one half nostril This study aims to compare different EETAs between transcran...

The transsphenoidal transplanum, transtuberculum approach to the suprasellar cistern, also called the “extended” transsphenoidal approach, has been used during the past 10 years by experienced transsphenoidal surgeons to remove a limited number of well-circumscribed suprasellar lesions (7, 8, 10, 17, 20–23, 29). Initially, a sublabial approach was generally used and visualization was provided w...
