In a brief outline of the surgical procedure the authors present visual documentation pointing out the key moments in a correctly performed trans-labyrinth craniotomy.
Postoperative function of facial nerve, complications and postoperative steady state functions are retrospectively evaluated in a cohort of 238 patients with vestibular schwannoma, having been operated on using the trans-labyrinth approach.
The facial nerve or anatomically preserved in 93.2%. The well functioning face one year after H-B I, II was preserved in 67% and H-B I, II, III in 78%. In 12 patients the reconstruction of facial nerve was performed and the functional result after one year is H-B III-IV in all patients. When we get any response at the end of the surgery upon stimulation of the proximal part of facial nerve where in comes out of the brain stem by 0.05-0.1 mA stimuli, a normal facial function H-B I, II may be expected to occur after one year. Electroneurography is unable to safely predict a badly functioning face on the long-term basis. Postoperative complications occurred in 18%, serious one requiring early revision surgery was encountered in 2.1%.
one patient died a week after the surgery (0.4%), postoperative liquorrhea occurred in 9%, meningitis in 2.1%, hematoma of abdominal wall after removal of fatty tissue in 0.8%, hydrocephalus in 1.7%, transient lesions of nerves IX and X in 1.7%, and transient lesions of nerve VI in 0.4%. Balance functions after one year: 0.24% of patients suffer from mild ataxia with instability after fatigue.
In our opinion the trans-labyrinth craniotomy is a method of choice in the therapy of vestibular schwannoma in all tumors larger than 1.5 cm and even smaller ones, where criteria for saving the hearing are impossible to observe.
