Preclinical Study of a Minimally Invasive Cochlear Implant Device Based on 3D Printing of a Custom Guide.

Objective: The aim of this study is to test the feasibility of a custom 3D-printed guide for performing a minimally invasive cochleostomy for cochlear implantation.

Study Design: Prospective performance study.

Setting: Secondary care.

ORGAVADS: establishment of tumor organoids from head and neck squamous cell carcinoma to assess their response to innovative therapies.

Background: Radiotherapy is one of the cornerstones of the treatment of Head and Neck Squamous Cell Carcinomas (HNSCC). However, radioresistance is associated with a high risk of recurrence. To propose strategies (such as combinations with drugs) that could over intrinsic radioresistance, it is crucial to predict the response to treatment.

The advantages of modified Thiel technique in head and neck surgical anatomy teaching.

Purpose: Thiel's body preservation method allows the donor body to retain color and soft tissue that are similar to those of a living individual. Since its initial description, the technique has not been developed much. Here, we propose a simpler protocol applied to the head and neck, making the technique easier, cheaper, and more accessible to a greater number of medical schools.

[Ten years of advances in head and neck surgery, how does this influence postoperative radiotherapy?].

Minimal invasive surgery and reconstructive surgery tend to become the standard in France in the management of head and neck tumors. The use of endoscopic approaches (through endoscopic endonasal/transoral approaches±robot-assisted) instead of open surgery and the use of reconstructive surgery using autologous (flaps) or heterologous materials aim to reduce surgical morbidity by making-up for the loss of substance to restore the function. The impact of these substantial changes in surgical techniques has not been assessed with respect to postoperative radiotherapy practice.

How to perform microscopic/endoscopic resection of large petrous apex lesions.

The endoscope and microscope can be used conjointly in certain sites, such as middle ear cholesteatoma or for resection of cerebellopontine angle tumours. Petrous apex tumours are classically accessed via a lateral otological approach, or, for the most anterior tumours, via an endonasal endoscopic approach. Surgical access via a lateral incision is limited inferiorly by the superior bulb of the internal jugular vein, medially by the labyrinth, facial nerve and internal auditory canal, superiorly by the dura mater, and laterally by the internal carotid artery.
