The translabyrinthine approach gives access to the internal auditory canal (IAC) through mastoidectomy and drilling of semicircular canals and vestibule. Due to iatrogenic damage to the membranous labyrinth, postoperative hearing loss is expected so that this Evaluating the efectiveness and complications of the Retrosigmoid, Translabyrinthine and Middle Fossa approaches in vestibular Schwannoma surgical management: a comprehensive systematic review and meta‐analysis of 6,889 patients Fabricio Garcia‐Torrico1 · Cristian D.

Vestibular Schwannoma’s Resection Surgical Approaches, Advantages and Disadvantages of Retrosigmoid, Middle Cranial Fossa and Translabyrinthine Surgical Approaches.

Volume: Surgery for Acoustic Neuroma: Translabyrinthine Approach. Topics include: Brain Tumors, Cranial Base Surgery. Part of the Cohen Collection. The translabyrinthine approach was reintroduced approximately 35 years ago 3 and is successfully used by several otologic specialist centers. 4–6 After developments in skull base surgery, neurosurgeons have become aware of the advantages of the translabyrinthine approach for vestibular schwannomas and for other skull base lesions.

Volume: Surgery for Acoustic Neuroma: Middle Fossa Approach. Topics include: Brain Tumors, Cranial Base Surgery. Part of the Cohen Collection. The translabyrinthine approach allows excellent access to the cerebellopontine angle (CPA) and provides exposure of the facial nerve from the brainstem to the stylomastoid foramen. Although hearing is sacrificed, the majority of the approach is extradural and skull base technique indicated brain retraction is avoided. The middle cranial fossa (MCF) approach for operating on acoustic neuromas (ANs) is an excellent treatment option for patients who still have hearing and whose tumors are small- to medium-size (< 2 cm). “MCF has a low risk of intracranial complication, offers excellent facial nerve outcomes and is arguably the best surgical procedure to preserve hearing,” says Ravi N.

The retrosigmoid, translabyrinthine, and middle fossa craniotomies are the three most commonly employed approaches for microsurgical resection. Each has inherent advantages and limitations, which The chosen approach for a given VS is highly variable based on the experience and background of the surgical team members. Tumor size and residual hearing are the most important factors influencing VS approach in centers that routinely use the translabyrinthine, retrosigmoid, and middle fossa craniotomies. There are variety of treatment options for acoustic neuroma removal: middle fossa surgery, retrosigmoid approach, translabyrinthine approach, SRT, and Cyberknife. Call to schedule an appointment.

Surgery is undertaken via one of three approaches: translabyrinthine (through removal of the mastoid air cell system and the vestibular apparatus); retrosigmoid (via a craniotomy usually undertaken collaboratively behind the ear); or the middle fossa route (via a craniotomy above the ear). 8 Surgery is usually undertaken collaboratively by an otolaryngologist and a neurosurgeon.

Translabyrinthine Approach:

The middle fossa approach is most often used for patients with small tumors and serviceable hearing, while the translabyrinthine approach provides wide access to the cerebellopontine angle, internal auditory canal and facial nerve with a low incidence of postoperative complications. Various approaches exist for surgical resection of acoustic neuromas and other The most common surgical approaches to address these tumors are retrosigmoid (RS) and translabyrinthine (TL) [2 – 3]. A third, middle fossa approach can be considered; however, it has a more limited indication for small intracanalicular tumors [4].

In this chapter, the three main operative approaches to the internal auditory canal and cerebellopontine angle—the retrosigmoid, the translabyrinthine, and the middle fossa approach—are discussed. The middle fossa approach is utilized usually in case of The translabyrinthine approach has proven to be a reliable and safe option to access the internal acoustic canal and the cerebellopontine angle with sacrifice of the hearing mechanism. Vestibular schwannomas are operated via one of the three main surgical approaches: the retrosigmoid, the translabyrinthine, or the middle fossa approaches. 1, 4,5 In contemporary surgical

Approaches to Acoustic Neuroma Surgery Surgical approaches for removal of an acoustic tumor include: Retrosigmoid approach (also known as the retromastoid approach or the suboccipital approach). This involves an incision behind the ear and removal of bone to expose the tumor. It can be used for any size tumor and, in patients with small tumors, can sometimes preserve The other transtemporal approaches are divided into three sections: (1) anterior transpetrosal approaches, describing anterior approaches within the temporal bone through the middle cranial fossa; (2) posterior

Comparison of the retrosigmoid approach and the translabyrinthine ...

Either the retro- or translabyrinthine approaches can be combined with other lateral skull base procedures to enhance exposure, depending on size and location of lesion being exposed and the patient’s hearing status such as the total petrosectomy approach with facial nerve translocation.

The retrolabyrinthine approach is an important skull base technique indicated for multiple pathologies of the posterior cranial fossa. This approach allows for preservation of hearing while directly accessing the cerebellopontine angle and avoiding manipulation of neural sturctures. Given the complex nature of this procedure, Topics include Brain Tumors it is necessary that all skull base surgeons have a It focuses on describing the translabyrinthine approach, including the key stages of cortical mastoidectomy, bony labyrinthectomy, skeletonization of structures, tumor removal, and closure. Alternative approaches like the middle fossa approach are also summarized.

The translabyrinthine approach

The translabyrinthine approach is generally used for patients with non-serviceable hearing or in cases when hearing preservation is not realistically feasible. Finally, the middle fossa craniotomy is reserved for small tumors confined to the internal auditory canal in patients with functional preoperative hearing.

A team approach between a neurotologist and a neurosurgeon offers the patient the expertise of both specialties and maximizes the chances for an optimal outcome. Vestibular schwannomas can typically be resected through 1 of 3 main surgical approaches: the translabyrinthine, the retrosigmoid, or the middle Middle Fossa fossa approaches. The TL approach offers good flexibility and may be extended and combined with other approaches to the posterior fossa, middle fossa, and midline skull base. The approach may be extended superiorly with division of the superior petrosal sinus and combined with transpetrosal techniques.

Indications for the Translabyrinthine Approach Vestibular schwannomas (VSs) have been resected via the translabyrinthine (TL), middle cranial fossa (MCF), or retrosigmoid (RS) approaches, based on their size/location of the bulk of the The Center for Acoustic Neuroma Dallas, Texas is one of the few centers with personal expertise and experience with the three general approaches to Acoustic Neuroma, including variations that we have developed over the years of dealing with these tumors.

Surgical removal remains one of the key treatment modalities for vestibular schwannomas. A team approach between a neurotologist and a neurosurgeon offers the patient the expertise of both specialties and maximizes the chances for an optimal outcome. Vestibular schwannomas can typically be resected through 1 of 3 main surgical approaches: the translabyrinthine, the Download scientific diagram | 8 Surgical approaches for vestibular schwannomas extirpation:a middle fossa, b translabyrinthine, and c retrosigmoid approach. (Figure from [1]. Reprinted with It focuses on describing the translabyrinthine approach, including the key stages of cortical mastoidectomy, bony labyrinthectomy, skeletonization of structures, tumor removal, and closure. Alternative approaches like the middle fossa approach are also summarized.

The chosen approach for a given VS is highly variable based on the experience and background of the surgical team members. Tumor size and residual hearing are the most important factors influencing VS approach in centers that routinely use the translabyrinthine, retrosigmoid, and middle fossa craniotomies.

Background The translabyrinthine approach was developed by William F. House, M.D., [1] who began doing dissections in the laboratory with the aid of magnification and subsequently developed the first middle cranial fossa and then the translabyrinthine approach for the removal of acoustic neuroma.
