The Effects of Using Hearing Aids and Hearing Assistive Technologies on Programmable Ventriculoperitoneal Shunt.

Background: To investigate interaction between behind-the-ear (BTE) hearing aids, hearing assistive technologies, and programmable shunt valve to understand how use of BTE hearing aids in patients who underwent ventriculoperitoneal shunt (VPS) surgery affects the settings of a programmable shunt valve.

Methods: In this study, we investigated the magnetic field (MF) generation of 3 BTE hearing aids made by different companies, 1 frequency modulated system using telecoil technology, and 1 wireless microphone technology and their interactions with 2 programmable shunt valves. All measurements were made in a silent booth using 2 different models.

How can periorbital oedema and ecchymose be reduced in rhinoplasty?

Oedema and ecchymose are frequent morbidities of septorhinoplasty, a facial surgical procedure for reforming the shape and functions of the nose. Periorbital oedema (PO) and periorbital ecchymose (PE) are normal occurrences, but are undesirable for patients undergoing the procedure for aesthetic purposes. The present study examined 65 patients who underwent open technique septorhinoplasty for aesthetic and functional complaints.
