<b><br>Introduction:</b> Although PET/CT is effective for staging HNSCC, its impact on patient management is somewhat controversial. For this reason, we considered it necessary to carry out a study in order to verify whether PET/CT helps to improve the prognosis and treatment in patients. This study was designed to address the impact of PET-FDG imaging when used alongside CT in the staging and therapeutic management of patients with HNSCC.
View Article and Find Full Text PDFIntroduction: Squamous cell carcinoma (SCC) of the vocal cord in stages I or II can be treated with radiotherapy (RT) or transoral CO laser microsurgery (TLM), with good oncological results.
Objectives: To study the survival of patients with SCC of the vocal cord in early stages, treated with RT or TLM, in a tertiary hospital.
Material And Methods: Disease-free survival (DFS), specific survival (SS), and overall survival (OS) were studied in patients diagnosed with stage I and II SCC of the vocal cord, for a span of 10 years of follow-up, based on sociodemographic characteristics of the patient and the primary treatment (TLM or RT).
Objective: The aim of this study is to find out if a single imaging test is enough to follow-up on an oncological post-treatment patient. In such a case, we would know which was more valuable after comparing the two, by CT or PET-CT.
Methods: Between January 2012 and July 2018, we collected data from all patients with previous medical history who were treated with a head and neck squamous cell carcinoma in our hospital, through surgery or by using an organ preservation protocol which we had done.
Background: Glottic squamous cell carcinoma (SCC) in stages I or II can be treated by transoral CO laser microsurgery (TLM) or exclusive radiotherapy (RT).
Objectives: To compare the oncological results of patients treated with TLM, to those treated with RT, in a tertiary hospital.
Material And Methods: Data from patients diagnosed with glottic SCC in stages I and II between 2004 and 2018 were analyzed.
Introduction: Head and neck squamous cell carcinoma is the seventh most common malignant tumor. The advances in treatment have improved the global survival rates in the past years, although the prognosis is still grave.
Objective: The aim of the present study is to evaluate the correlation between positron emission computed tomography and computed tomography at the time of staging a previously untreated head and neck squamous cell carcinoma, and to determine which of the two imaging techniques gives us more information at the time of initial diagnosis.
IgG4 related disease (igG4-RD) is a pathological process which integrates a large number of diseases of unknown pathogenesis, considered as being exclusive to many different organs. Diagnosis is established through histological, radiological and serological criteria. Treatment is based on long term corticosteroids; rituximab being used only in refractory cases.

Design: This was a prospective, multicenter, repeated-measures study.
The cochlear implant as a tinnitus treatment.
Acta Otorrinolaringol Esp
July 2014
Introduction And Objectives: Tinnitus is a symptom of high prevalence in patients with cochlear pathology. We studied the evolution of tinnitus in patients undergoing unilateral cochlear implantation for treatment of profound hearing loss.
Methods: This was a longitudinal, retrospective study of patients that underwent unilateral cochlear implantation and who had bilateral tinnitus.
Introduction: To solve certain problems that arise in cochlear implant, sinus and skull base surgery, the use of bone cement (PolyBone®) has been introduced in our department. With the goal of making use of surgical bone cements, combining bone growth factors and polyphosphates has allowed the study of these biological materials.
Materials And Results: We present a total of 28 patients aged between 2 and 69 years (mean age of 29.
Introduction And Goals: Tubotympanal mucociliary function is damaged in patients with otitis media with effusion. Our objective was to study its situation and recovery after timopanostomy tube insertion.
Methods: We evaluated the mucociliary activity of the ear and Eustachian tube with scintigraphy in four groups of adults with chronic otitis media with effusion after ventilation tube insertion.
[Study of olfactory function for pyridine in healthy population: influence of variations in humidity].
Acta Otorrinolaringol Esp
December 2008
Objectives: We study the influence of humidity and its variations on human olfactory threshold for pyridine.
Material And Method: Olfactory function was tested on 154 healthy volunteers without rhino-sinusal pathology. Pyridine was used as odorant in four different concentrations investigating the ability to detect the stimulus and the acuity to estimate its intensity.
Objective: Little is known about incidence of laryngo-pharyngeal reflux (LPR) and gastroesophageal reflux (GER) in the early postoperatory period of laryngectomy. To evaluate the effect and characteristics of the LPR and GER in laryngectomized patients, by means of double pH-metry during 48 hours after surgery.
Material And Method: In 50 patients, 48-hour double-probe pH monitoring was performed in postoperative of laringectomy, after a intraoperatory placement.
