No Shinkei Geka 2022 May;50(3):496-507

Department of Neurological Surgery, Nippon Medical School.

Skull base surgery is a surgical field that involves the cooperation of multiple surgical and medical specialties, including neurosurgery, head-neck surgery, plastic-reconstructive surgery, radiation oncology, as well as multiple medical supporting teams. This field has been developed with the collaborative efforts of these medical specialties, and its history can be divided into five phases: Beginning of surgery(Prior to 1940); Early skull base surgery driven by the ENT-HN surgery group(1940-70); Conventional skull base surgery development based on anatomical, physiological knowledge and microsurgical equipment and technique(1970-90); Reflection and consolidation of the surgical dimension(1995-2005); and Evolution of endoscopic and new skull base surgical techniques(2005-). Several topics and advancements have improved this surgical field, such as access to the cavernous sinus, petrosal-temporal bone, and foramen magnum; concepts of minimally invasive surgical techniques; advanced endoscopic instruments; knowledge of biological assessments; and development of surgical robotics.

Temporal Bone Squamous Cell Carcinoma: Molecular Markers Involved in Carcinogenesis, Behavior, and Prognosis: A Systematic Review.

Int J Mol Sci 2022 Apr 20;23(9). Epub 2022 Apr 20.

Department of Neuroscience-DNS, Otolaryngology Section, University of Padova, 35128 Padova, Italy.

Temporal bone squamous cell carcinoma (TBSCC) is an uncommon malignancy with a poor prognosis in advanced cases. The dismal outcome of advanced TBSSC cases is largely due to the cancer's local aggressiveness and the complex anatomy of this region, as well as to persistent pitfalls in diagnosis and treatment. Molecular changes occur in malignancies before any morphological changes become visible, and are responsible for the disease's clinical behavior. Read More

Human vestibular schwannoma reduces density of auditory nerve fibers in the osseous spiral lamina.

Hear Res 2022 05 7;418:108458. Epub 2022 Feb 7.

Department of Otolaryngology - Head and Neck Surgery, Harvard Medical School, Boston, MA, USA; Eaton Peabody Laboratories and Department of Otolaryngology - Head and Neck Surgery, Massachusetts Eye and Ear, Boston, MA, USA; Department of Otolaryngology, Head and Neck Surgery, Stanford University School of Medicine, Stanford, CA, USA. Electronic address:

Hearing loss in patients with vestibular schwannoma (VS) is commonly attributed to mechanical compression of the auditory nerve, though recent studies suggest that this retrocochlear pathology may be augmented by cochlear damage. Although VS-associated loss of inner hair cells, outer hair cells, and spiral ganglion cells has been reported, it is unclear to what extent auditory-nerve peripheral axons are damaged in VS patients. Understanding the degree of damage VSs cause to auditory nerve fibers (ANFs) is important for accurately modeling clinical outcomes of cochlear implantation, which is a therapeutic option to rehabilitate hearing in VS-affected ears.
