A comparative study of endoscopy and microscopy in exposure of posterior fossa through the intradural subtemporal keyhole approach
Objective
To comparatively analyze the differences between endoscopy and microscopy in area of exposure and surgical freedom in posterior fossa through the intradural subtemporal keyhole approach and to explore the advantages of neuronavigation in that approach.
Methods
Twenty endoscopic intradural subtemporal keyhole approaches (EISKA) were performed on 10 cadaveric adult heads. An intradural Kawase approach and a navigation-assisted intradural Kawase approach were then carried out on a random side of each specimen. Related anatomic structures were observed through endoscope and microscope at the end of each approach. Anatomic exposure and surgical freedom were measured by transparent graph paper and were analyzed.
Results
Compared with microscopy, the superior, inferior and medial limits through endoscopic exposure were increased by 2.9±1.0 mm, 15.7±1.5 mm and 10.2±1.1 mm, and the surgical freedom was increased by 2.9±1.0 mm, 7.6±1.9 mm and 6.0±1.7 mm (P<0.05) in the intradural subtemporal keyhole approach. In intradural Kawase approach, the anatomic exposure was increased by 2.7±0.9 mm, 20±1.2 mm and 29.5±0.7 mm and the surgical freedom was increased by 2.7±0.9 mm, 14.8±1.4 mm and 8.8±1.4 mm (all P<0.05). In navigation-assisted intradural Kawase approach, the anatomic exposure was increased by 3.1±1.0 mm, 20.3±2.4 mm and 29.9±0.7 mm, and the surgical freedom was increased by 3.1±1.0 mm, 15.3±1.6 mm and 8.8±1.3 mm (P<0.05). Using a frameless navigational device, the inferior limit of the anatomic exposure was increased by 3.8±2.2 mm in endoscopy and 3.5±0.7 mm in microscopy, and the surgical freedom was increased by 2.7±0.9 mm in endoscopy mm and 2.2±1.2 mm in microscopy (all P<0.05).
Conclusions
The EISKA could provide more anatomic exposure and surgical freedom mainly in the superior, inferior and medial directions of the brainstem regions. More inferior anatomic exposure and surgical freedom of the posterior cranial fossa could be obtained by navigational assistance.
