Background: Papillary tumors of the temporal bone are very rare neoplasms that show locally aggressive behavior though they have low-grade histologic features. The best treatment for these tumors is a radical resection. However, if the tumor is very large, local invasiveness and hypervascularity can prevent surgeons from achieving a complete resection. As an additional treatment for the residual tumor, it remains controversial whether radiation therapy has any role.
Case Description: The authors describe a 53-year-old woman who suffered from left-sided tinnitus, hearing loss, and diplopia due to a large aggressive papillary tumor of the temporal bone. Radiosurgery was very effective for the tumor, which had regrown a few years after conventional radiation therapy and chemotherapy.
Conclusions: The authors conclude that radiosurgery should be considered as an option for the treatment of aggressive papillary tumor of the temporal bone.

Surgical Approaches to Pre-Auricular Cutaneous Squamous Cell Carcinomas Extending to the Temporal Bone.

Department of Otolaryngology, Head and Neck Surgery, Princess Alexandra Hospital, Queensland Skull Base Unit, Brisbane, Queensland, Australia.
Background: Standardized surgical approaches to advanced pre-auricular cutaneous squamous cell carcinomas (cSCC) are lacking.
Methods: Fifty-four patients who underwent lateral temporal bone resection (LTBR) for pre-auricular cSCC were grouped into "Levels" of increasing disease spread. Surgical approaches to achieve negative-margin resection were designed for each Level and replicated on cadaveric specimens.

This study aimed to investigate the efficacy of inverted door flap (IDF) combined with transcanal approach to the tympanic antrum (TCAA) technique under the endoscope for treatment of middle ear cholesteatoma. Outcomes of patients treated with combined techniques at the First People's Hospital of Foshan City between March 2021 and March 2023 were evaluated. A total of 31 patients (33 ears, 16 males and 15 females) aged (42.

Jacob Fidelis Ackermann was a German Medical Doctor born in 1765 in the city of Rüdesheim. Between 1789 and 1815 years he was professor of medicine at the universities of Mainz and Heidelberg, teaching the disciplines of anatomy, physiology, botany, and natural history. In his famous work on basilar invagination, Ackermann described and illustrated the cranial base flattening in two skulls from Italy.

Department of Otorhinolaryngology-Head and Neck Surgery, Keio University School of Medicine, 35 Shinanomachi, Shinjuku-ku, Tokyo, 160-8582, Japan.
Objective: Intraoperative systems for monitoring facial nerve function, in which temporal electrical stimulation is applied to the facial nerve through electrodes, are used in many surgeries requiring facial nerve preservation; however, continuous stimulation or quantitative evaluation of facial nerve function is difficult with this approach. We examined the usefulness of a continuous and quantitative facial nerve-monitoring system for temporal bone lesions by using our experience to modify the existing methods used for cases involving vestibular schwannomas.

Ultra-high-resolution CT of the temporal bone before cochlear implantation for pre-operative prediction of chorda tympani nerve management and round window access.

Guilloz Imaging Department, Central Hospital, University Hospital Center of Nancy, Nancy, 54000, France.
Background And Purpose: To evaluate various anatomical parameters and their relationship to chorda tympani nerve (CTN) injury and round window (RW) access during cochlear implantation.
Materials And Methods: Ultra-high-resolution CT images of 66 patients were retrospectively reviewed and compared with operative reports. The facial recess and the round window were analyzed, mainly using the chorda-facial angle (CFA), the width of the facial recess, the CTN-tympanic annulus distance, the RW-mastoid portion of the facial nerve angle, and the type of RW.
