https://www.selleckchem.com/products/pfi-3.html Vestibular schwannoma is a benign tumour that originates in the eighth cranial nerve. It is termed intralabyrinthine schwannoma (ILS) when it develops in the inner ear, this being a rare origin. We present our experience in the management of three patients with ILS. The results of tumour excision and cochlear implantation were evaluated in three patients with ILS two intracochlear schwannomas (ICS) and one intravestibular schwannoma (IVS). Prior to surgery, all patients presented progressive sensorineural hearing loss and tinnitus. Complete tumour resection and cochlear implantation was possible in all patients, with favourable hearing rehabilitation. The therapeutic approach will depend on tumour size, growth rate, degree of hearing loss and presence of vestibular symptoms. Cochlear implantation (CI) in patients with ILS is possible when the cochlear nerve is present and functional. CI in patients, whether or not preceded by tumour excision, is an option with good hearing results in selected patients.

T-14 and TAHSI are validated and reliable specific questionnaires which measure the quality of life in paediatric patients with adenotonsillar disease. The present study aims to compare the adapted and validated versions in Spanish of these two questionnaires (T-14-s and s-TAHSI) in order to assess the preferential use of either of them in our environment. A multicentre prospective cross-sectional study was carried out between November 2015 and April 2016, to determine the possible correlation between these two instruments. Subjects aged from 2 to 16 years with indicati
