Posterior cordotomy in bilateral vocal cord paralysis using monopolar microelectrodes and radiofrequency in 18 patient
Cis-diaminedichloro platinum ototoxicity. An experimental study.
Four groups of guinea pigs received different doses of cis-platinum. SEM and TEM showed a direct relation between the dose and the damage. The first row of OHC is the first one to be damaged. The IHC are more resistant than the OHC. The pattern of destruction is similar to the one produced by the aminoglucoside antibiotics.

Sistema inteligente para protocolizar el diagnóstico de invasión ganglionar en el cáncer de laringe
Laryngeal carcinoma is the most frequent malignant tumour in head and neck. Node invasion is known to be one of the most important prognostic factors. The aim of this study has been to design an intelligent system to perform a diagnostic algorithm of metastasic neck nodes. 122 clinical reports of patients diagnosed of laryngeal carcinoma in our department have been reviewed. The compiled data have been: tumor site, T stage, N stage (clinical, after CT scan and post-surgery). The method used to design the intelligent system has been the ID3, which is able to generate a minimal decision tree. Palpation has been the variable that has given more information about node invasion. CT has proved to…
Acute tissue damage induced by monopolar microelectrodes and radiofrequency in vocal cords after transoral cordectomy
Abstract Introduction: In 2006 and 2009, we reported the levels of acute and chronic tissue damage after cordectomy associated with use of the microlectrodes using high frequency energy. In 2010, we shifted to radiofrequency rather than high frequency electrogenerators. Objective: The aim of this study is to evaluate acute tissue damage in the larynx after cordectomy using microelectrodes coupled to a radiofrequencygenerator. Methods: We studied 22 patients with a stage T1 glottic squamous cell carcinoma. The patients were randomly assigned to the two operating mode: cutting or coagulation (11 patients each mode). The strength of the study is that there are no previous studies on the effect…
[Transphenoidal endoscopic approaches for pituitary adenomas: a critical review of our experience].
Abstract Background The surgical approach to the pituitary fossae has evolved from transcranial to sublabial and transseptal microscopic ones, up to the current transsphenoidal endoscopic approach. Objectives To present our experience in the transnasal transsphenoidal approach for pituitary adenomas and the modifications introduced to improve tumoral resection and to lower iatrogenia. Material and methods Over nine years, we operated on 37 patients with pituitary adenomas using the transsphenoidal endoscopic approach. We utilised optical lens of 0° (approach) and 30° (adenoma resection), optic navigator, surgical instruments for nasal endoscopic and pituitary surgery. During the neurosurgic…
Abordajes transesfenoidales endoscópicos de los adenomas hipofisarios: una revisión crítica de nuestra experiencia
Resumen Introduccion El abordaje quirurgico de la region hipofisaria ha evolucionado desde las vias transcraneales, a las sublabiales y transseptales microscopicas hasta los abordajes endoscopicos actuales. Objetivos El objetivo de este trabajo es exponer y reflexionar sobre nuestra experiencia en el abordaje transnasal transesfenoidal endoscopico de los tumores hipofisarios, con las modificaciones que hemos introducido para mejorar la exeresis del tumor y disminuir la iatrogenia. Material y metodos A lo largo de 9 anos hemos intervenido a 37 pacientes afectos de adenomas hipofisarios mediante abordaje transesfenoidal endoscopico. Utilizamos lentes de 0 y 30 grados, navegador optico, instru…
