Radical resection of trigeminal schwannoma at the cerebellopontine angle with support of the digital robotic exoscope Synaptive Modus V system: A case report and literature review

Abstract

Rationale and patient concerns: We report on a 67-year-old woman who experienced drowsy mental status, facial numbness, and hearing loss on the right side; the symptom gradually worsened over the last 4 years. Brain magnetic resonance imaging revealed a 4.8 × 1.8 × 2.6 cm lesion located in the right cerebellopontine angle. Interventions: She underwent surgery with the retrosigmoid suboccipital approach and support from the digital robotic exoscope Synaptive Modus V system. To the best of our knowledge, this is the first reported case that used the robotic exoscope system in Vietnam, and also in Asia. Diagnosis: We performed radical resection of the tumor, the surgery position and the pathology result concluded the diagnosis was trigeminal schwannoma. Outcomes: After 30 months of follow-up, she fully recovered and the magnetic resonance imaging showed radical resection of the tumor. Lessons: The aim of this study is to share our experience with the robotic exoscope system, which can improve optical field and image resolution, hence creating an opportunity for surgery that otherwise is impossible. The application of this robotic exoscope system is a breakthrough in neurosurgery in developing countries, such as Vietnam.

Exoscopic Microsurgery: A Change of Paradigm in Brain Tumor Surgery? Comparison with Standard Operative Microscope

“…In particular, in the case of cranial neurosurgery, the use of the exoscope has been widely described for the surgical treatment of brain tumors, both in adult and pediatric patients [20,30,[37][38][39][40], and only few papers have reported a comparison between the operative microscope and the exoscope for brain tumors [26,41,42]. In the study of Takahashi [43], published in 2018, 14 microneurosurgical procedures were retrospectively assessed by 9 neurosurgeons after the procedure by a questionnaire comparing the exoscope (ORB-EYE™) to the standard operative microscope.…”

Laparoscopic cholecystectomy induce tension pneumocephalus in a patient with ventriculoperitoneal shunt: A case report and literature review

“…She was admitted to Tam Anh Hospital, a facility that can diagnose and treat patients with neurological disorders using cutting-edge methods in Vietnam. [4] She had a medical history of mild mental retardation, 20 years ago she experienced hydrocephalus and was treated with VPS; 2 years ago, she experienced hydrocephalus again because of obstruction of the VPS, and the new VPS was replaced.…”
