Article Abstract

In vestibular schwannoma surgery, neuromonitoring is essential to accomplish sufficient tumor resection while avoiding neurologic damage. An ideal neuromonitoring method should include a real-time alert system, quantitative evaluation, and functional (not mechanical) assessment.Video 1 demonstrates facial and hearing preservation surgery for vestibular schwannoma by the retrosigmoid transmeatal approach, under intraoperative continuous facial nerve monitoring and auditory brainstem response. Using a ball-type stimulating electrode placed on the proximal facial nerve, the evoked facial nerve electromyograms were continuously monitored by direct 1-Hz stimulation throughout the near-total tumor resection. The patient had no postoperative facial or hearing deterioration. The patient consented to the procedure before the surgery.

Pneumatisation patterns surrounding the internal acoustic meatus.

Ann Anat

September 2025

Division of Anatomy, Department 1, Faculty of Dentistry, "Carol Davila" University of Medicine and Pharmacy, 050474 Bucharest, Romania. Electronic address:

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.
