How I Do it - Neurosurgical Techniques



The use of endoscopes in transnasal surgery offers increased visualization. To minimize rhinological morbidity without restriction in manipulation, we introduced the mononostril transethmoidal-paraseptal approach.


The aim of the transethmoidal-paraseptal approach is to create sufficient space within the nasal cavity, without removal of nasal turbinates and septum. Therefore, as a first step, a partial ethmoidectomy is performed. The middle and superior turbinates are then lateralized into the ethmoidal space, allowing a wide sphenoidotomy with exposure of the central skull base.


This minimally invasive transethmoidal-paraseptal approach is a feasible alternative to traumatic transnasal concepts with middle turbinate and extended septal resection.

The video “trans-ethmoidal, paraseptal approach to the sella” illustrates the main steps of a minimally invasive, mono-nostril approach to the sella preserving the middle turbinate and the septum, yet allowing a mono-nostril bimanual resection. (MP4 299966 kb)
