    Auditory evoked potentials – underlying principles
    (2018) Biagio, de Jager
    Auditory evoked potentials (AEPs) is the collective term for electrical potentials evoked by externally presented auditory stimuli from any part of the auditory system, from the cochlea to the cerebral cortex 1. Evoked responses represent electrical potentials as a manifestation of the brain’s response to sound.

    Mobile phone and cell phone audiometry
    (2024) Mahomed-Asmail, Faheema; Swanepoel, De Wet; Fagan. Johan
    Over 60% of the global population uses mobile phones (O'Dea 2020), with pene-tration rates steadily increasing as mobile technology becomes more affordable and accessible (Cvrkel 2018). The widespread availability of mobile phones has led to the development of mobile health (mHealth) applications designed to improve access to and uptake of healthcare services (Valenzuela et al. 2018, World Health Organization 2021, Rono et al. 2021). mHealth applications have been explored in various healthcare services, including hearing health.

    Rhinoplasty: Surgery of the Osseocartilaginous Vault
    (2025-03-20) Trenité, GJ Nolst
    Looking at the sequence of operative steps, most rhinoplastic surgeons prefer to perform surgery of the osseocartilaginous vault after tip surgery. One of the main reasons for this is that, by applying an external nasal dressing immediately after osteotomy, oedema and ecchymosis can be prevented or at least diminished. Another reason is that, to obtain an aesthetic balance, in certain cases it is easier to adapt the form of the osseocartilaginous vault to the form of the tip, rather than vice versa. In this chapter, surgery of the osseocartila ginous vault is divided into five sections: •Hump resection •Osteotomies •Management of special bony pyramid problems •Radix nasi surgery •Cartilaginous vault surgery
