Objective: The use of endoscopic assistance in retrosigmoid approach for tumors of the cerebellopontine angle brought undoubted technological advantages in skull base surgery. Nonetheless, the use of the endoscope is not as widespread as it could be. The aim of the study is to analyze the impressions of neurosurgeons and otologists with different experience in vestibular schwannoma surgery, experiencing the introduction of the endoscope in surgical daily practice.
Methods: All patients undergoing vestibular schwannoma surgery were recruited in the period from January 2019 to December 2020. The endoscope-assistance and a minimum follow-up of 12 months were considered inclusion criteria. An eight items questionnaire was administered to the surgeons who used endoscope-assistance during surgery.
Results: A total number of 20 patients were recruited. Five surgeons experienced the use of 0° and 45° optics in the "pre-resection" and "intra-meatal" phases of the procedures. The survey gave positive feedbacks on the introduction of the endoscope in vestibular schwannoma resection. The main drawback was the difficulty to manage the use of angled optics.
Conclusions: Despite the known limitations of the study, the idea of investigating surgeons' impressions on the use of the endoscope could be another motif to explain why this instrument and its diffusion is limited despite its advantages in vestibular schwannoma surgery.

Purpose: This study aimed to investigate the prevalence and anatomical patterns of temporal bone pneumatisation surrounding the internal acoustic meatus (IAM), specifically across its three anatomical regions: the porus acusticus internus (medial opening), the proper IAM (tubular midportion), and the fundus (lateral end). A secondary objective was to evaluate the association between pneumatisation and the thickness of the overlying tegmen in each region.
Methods: A total of 160 IAMs (80 patients, bilateral assessment) were analyzed using cone-beam computed tomography (CBCT).

Objective: Ménière's disease (MD) presents with episodic vertigo, hearing loss, and tinnitus; however, its diagnosis remains challenging owing to symptom overlap with other vestibular disorders. We evaluated the diagnostic value of dissociation between caloric test and video head impulse test (vHIT) results in MD compared to vestibular schwannoma (VS) and benign paroxysmal positional vertigo (BPPV).
Methods: A retrospective analysis included 195 patients with MD ( = 51), VS ( = 112), or BPPV ( = 32).

Vestibular Schwannomas are frequent tumors of the cerebellopontine angle, classically presenting with cochlear and facial nerve alteration. They tend to have histopathological and intratumoral degeneration seen on MRI, and can cause CSF obstruction with hydrocephalus with subsequent visual loss. We present a case of bilateral visual loss from papilledema, with no history of hydrocephalus or increased intracranial pressure.

Objective: To compare the outcomes of vestibular schwannoma surgeries over the past decade, focusing on surgical approach, facial nerve function, tumor recurrence, and to standardize a classification system for the extent of tumor resection.
Study Design: A retrospective cohort study involving 197 patients who underwent vestibular schwannoma surgery between January 2014 and December 2023.
Methods: Data on demographics, tumor characteristics, surgical approach, and facial nerve function were collected.

Greater superficial petrosal nerve (GSPN) schwannomas are exceptionally rare and have not been previously reported to present with acute hemorrhage. In contrast, hemorrhagic vestibular and trochlear schwannomas have been described, often presenting with abrupt neurological symptoms. We report a case of a 41-year-old woman who presented with a sudden-onset headache and vomiting.
