“…Good hearing threshold and vestibular function preservation are findings often present in arachnoid cyst, this suggests that a middle temporal fosse approach 37 or a retrosigmoid one 38 can be the good option to preserve the nerve functions. The endoscopic approach 19,39 would be the best choice but not all surgeons are comfortable with it.…”

PubMed and Google Scholar searches using the following keywords: arachnoid cyst, internal auditory canal, temporal bones study, schwannoma of internal auditory canal, cystic schwannoma, MRI findings, surgery of internal auditory canal. Only the article where three keywords, included always arachnoid cyst, were considered. The study analyzed the etiopathogenesis of arachnoid cyst, hearing and vestibular symptoms and temporal bone findings. Review and conclusion: The author identified and reviewed a total of 46 articles. The results showed high incidence of hearing loss that was the more common symptom than vestibular one. Arachnoid cyst carried out more compression on the vestibular nerves than on the cochlear one. The review allowed us to identify which mechanism of damage arachnoid cyst acting on the nerves. It is necessary to consider the arachnoids cyst in differential diagnosis with tumors and pathologies involving the internal auditory canal.

“…Postoperatively, permanent facial nerve paresis/paralysis was observed in neither cases. According to another study by Marchioni et al (15), although the hearing preservation is not possible with the ETTA, it is an effective approach for the resection of small intracanalicular acoustic neuroma with good postsurgical facial nerve function. Wick et al (3) reported successful gross total resection of vestibular schwannomas in 4 patients (3 with Koos grade I and 1 with grade III) with a good long-term facial nerve function postoperatively.…”

Surgical Landmarks of the Endoscopic Transcanal Transcochlear Approach: A Cadaveric Study

et al. 2019

Background: The lateral skull base lesions are one of the most challenging parts of the head and neck. Surgical approaches for this area are complex and difficult. Although endoscopic approaches in skull base surgeries have progressed dramatically in recent years, there are few studies concerning these approaches. Objectives: This study aimed to describe the endoscopic transcanal transcochlear approach (ETTA) to reach the internal auditory canal (IAC) in the cadaveric temporal bone specimen. Methods: First, pre-and post-operative high resolution computed tomography (HRCT) images of the transcanal transcochlear pathway were obtained and 3D segmentation was performed using 3D Slicer software. The anatomic landmarks were identified using the endoscopic approach with and without navigation guide. Surgeries were done and the feasibility and challenges were evaluated. Results: The internal auditory canal (IAC) was accessed via the ETTA. Anatomic landmarks were looked and a surgical corridor was identified with HRCT segmentations and images obtained during surgery. Conclusions: We tried to increase our learning curve and extend surgical experience in lateral skull base surgery via minimally invasive ETTA. The increased endoscopic skills and the use of auxiliary tools such as a navigation guide may be helpful for successful access to the lateral skull base.

“…Transpromontorialer endoskopischer Zugang Für kleine intrakanalikuläre (intrameatale) oder intralabyrinthäre Tumoren wird von Marchioni et al [36] auch der ausschließlich transpromontoriale endoskopische Zugang (erstmalig 2012 durchgeführt) oder der zumindest endoskopisch assistierte mikroskopische Zugang propagiert. Vorteilhaft sind die gute anatomische Sicht und eine schnelle postoperative Erholung.…”

“…Bei dieser Art der Resektion wurde von den Autoren kein Erhalt des Modiolus und Hörnervs angestrebt. Eine Hörrehabilitation mittels Kochleaimplantat ist daher bei diesem Verfahren nicht möglich [36].…”

ZusammenfassungPrimäres Ziel der Behandlungsstrategie von Vestibularisschwannomen ist der Erhalt bzw. die Optimierung der Lebensqualität unter bestmöglicher Erhaltung der Nervenfunktionen. Einfluss auf das Management von Vestibularisschwannomen haben in erster Linie Tumorgröße, Tumorlage, Wachstumstendenz, Alter und Komorbiditäten sowie audiovestibuläre Symptome, d. h. Gleichgewichts- und Hörstörungen.
