[Ligation of the sphenopalatine artery in posterior epistaxis. Retrospective study of 50 patients].

Objectives: The aim of this study was to evaluate the efficacy of endoscopic ligation of the sphenopalatine artery in the treatment of severe posterior epistaxis.

Methods: We have carried out a retrospective study on 50 patients hospitalised with posterior recurrent epistaxis, in whom posterior nasal packing was not effective. All of them underwent surgical treatment, with endoscopic ligation of the sphenopalatine artery to control the epistaxis.

[Study of the relationship of stapedial reflex thresholds induced during cochlear implant surgery and the highest hearing comfort of paediatric patients].

Introduction And Goals: We have studied the relationship between the minimum stapedial reflex thresholds induced by means of the intra-operative stimulation of the cochlear implant and the post-operative thresholds of highest auditory comfort level.

Methods: We have assessed the maximum auditory comfort at the end of the first and second quarters following activation of the cochlear implant, by which time the strategy for codification of the stimuli and the programming map are considered to be already stable. The study was carried out at our cochlear implants unit.
