BACKGROUND Supracricoid partial laryngectomy is a surgical technique that preserves laryngeal function. METHODS A retrospective review of clinical records identified 41 patients that underwent supracricoid partial laryngectomy at our institution since 1998. In all, 26 patients with a minimum follow-up of 3 months were alive with a functioning larynx. All(More)
OBJECTIVE To review the oncologic outcomes of a series of supracricoid partial laryngectomy. DESIGN Case series with chart review. SETTING La Paz University Hospital, Madrid, Spain. PATIENTS Forty-one patients with glottic or supraglottic squamous cell carcinoma who underwent supracricoid partial laryngectomy between 1998 and 2008 at the authors'(More)
INTRODUCTION AND OBJECTIVES Voice alteration is a common event following endotracheal intubation. The objective of this study is to describe strobolaryngoscopic and spectrogram changes after endotracheal intubation, and attempt to identify a relationship between these changes and also with anaesthetic variables. MATERIAL AND METHOD Thirty-eight patients(More)
Computers play an important role in voice analysis both in research and in the clinic. We have revised some basic concepts in signal digitization and some of the options present in the different voice analysis systems as: intensity and fundamental frequency measurement, perturbation calculation (jitter and shimmer) and spectrographic analysis. Clinical(More)
INTRODUCTION AND OBJECTIVE The risk of developing hypocalcemia is the reason for prolonged hospitalisation after total thyroidectomy. The objective of this study was to validate parathyroid hormone measurement for predicting post-thyroidectomy hypocalcemia. MATERIAL AND METHODS Eighty-two patients who underwent total or completion thyroidectomy from(More)
The quotient between the maximum phonation time (MPT) of the sound /s/ and a vowel sound, measures the relation of resistances to the expiratory air flow. When the sound /s/ is emitted, resistance is located at the teeth, and when a vowel is phonated, the site of resistance is the glottis. Estimating the quotient instead of measuring only the MPT, we avoid(More)
INTRODUCTION AND OBJECTIVES Laryngeal electromyography, together with clinical evaluation, is a valuable tool in voice disorder management. It assesses the integrity of laryngeal nerves and muscles, contributing to the diagnosis of many diseases, especially laryngeal movement disorders. Our purpose was to describe the experience of the first Spanish series(More)
OBJECTIVE To report the oncologic and functional outcome of patients undergoing near-total laryngectomy. STUDY DESIGN AND SETTING A retrospective analysis was carried out from 1991 through 1998. RESULTS Eighty-seven patients underwent near-total laryngectomy. The Kaplan-Meier overall survival, cause-specific survival, and relapse-free survival estimates(More)
We report a rare case of dyspnea due to enlargement of the epiglottis in a severely immunocompromised patient. The child underwent a previous tracheostomy at another hospital because of respiratory distress under the diagnosis of acute epiglottitis. The patient was subsequently decannulated without incident. One year later, the child developed a new episode(More)
Using this test, we measure maximum and minimum vocal capacity (sound pressure in dB) from the lowest to the highest frequency that a person can emit and sustain. These measurements are represented on an easily interpreted graph that allows the magnitude of the vocal area to be evaluated. We made phonetograms of persons with nodules (3), polyps (16) and(More)
