Inadvertent laceration of the jugular bulb is a potentially serious complication of the retrosigmoid transmeatal approach to vestibular schwannomas. Here, the authors present the case of a 51-year-old woman with a right Hannover T4a vestibular schwannoma and bilateral high-riding jugular bulb, which was opened during drilling of the internal auditory canal (IAC). They highlight the immediate management of this complication, technical nuances for closing the defect without occluding the jugular bulb, and modifications of the standard technique needed to continue surgical resection. The video can be found here: https://stream.cadmore.media/r10.3171/2021.7.FOCVID2155.

To describe the distribution of jugular bulb position and pneumatization of posterior lip of internal auditory meatus (IAM) in patients with vestibular schwannoma (VS). This retrospective study included 43 patients who had a thin slice (< 2 mm) CT temporal bone for preoperative planning of retrosigmoid approach for excision of VS between March 2011 and March 2021. On computed tomography (CT), high riding jugular bulb was defined by its relationship to IAM and correlated with type of jugular bulb according to Manjila et al.

Background: Achondroplasia, the most prevalent form of skeletal dysplasia involving short stature, necessitates a multidisciplinary approach that includes otology and auditory rehabilitation. Despite this, the clinical characteristics of hearing loss and otologic manifestations in achondroplasia patients remain poorly defined. This study aimed to explore the prevalence and treatment outcomes of otologic disease in individuals with achondroplasia.

Background: The human skull contains various foramina, including the posterior condylar canal (PCC), which allows the passage of emissary veins. The PCC connects the jugular foramen to the condylar fossa and facilitates venous drainage between the jugular bulb and suboccipital venous plexus. Due to its variable size and location, the PCC can be mistaken for pathological structures, posing challenges during neurosurgical procedures.

An experience with two rare complications during surgery of vestibular schwannomas (VSs) is presented, and measures to avoid and manage the complications are discussed.Case A: Spinal cord ischemia in semi-sitting position: A 47-year-old with a giant vestibular schwannoma (VS) underwent surgery through a retrosigmoid approach in the semi-sitting position. The intraoperative phase was uneventful, except for an episode of moderate hypotension.
