[Cutaneous squamous cell carcinoma of the head and neck].

Objective: Cutaneous squamous cell carcinoma (cSCC), predominantly located on the scalp and face, is the second most prevalent skin cancer globally. Due to the increasing elderly population and rising incidence of cSCC, it has been gaining relevance in otorhinolaryngology.

Material And Methods: This review article is based on a selective PubMed literature search, German and European guidelines and the clinic's own experience.

In vitro comparison of self-expanding versus balloon-expandable stents in a human ex vivo model.

The objective was to compare the radial strength and expansile precision of self-expanding stents and balloon-expandable stents in a human cadaver bifurcation model. Seven different self-expanding (LUMINEXX, JOSTENT SelfX, JOSTENT SelfX hrf, Sinus-Repo, Sinus SuperFlex, Easy Wallstent, SMART) and four different balloon-expandable stent models (Palmaz, Sinus Stent, SAXX Medium, JOSTENT peripheral), each type 10 stents (total n = 110 stents) were implanted into the common iliac arteries of human cadaver corpses. The maximum stent diameter was 10 mm for all models.

Resistance to hoop stress in balloon expandable stents: evaluation in an ex vivo model.

Rationale And Objectives: To develop a new model for a more realistic evaluation of radial strength and elastic recoil of balloon expandable stents using a new ex vivo model in human cadaver bifurcations of the aorta.

Materials And Methods: Four different stents (each group n = 10) were implanted in cadaver common iliac arteries. Randomization was performed either to right or left iliac artery.
