Implicación clínica de la lesión iatrogénica de la cuerda del tímpano en la cirugía de la otosclerosis

Introduction: Damage to the chorda tympani nerve is frequent during otologic surgery. This article studies the clinical outcomes of the nerve's section versus its conservation in otosclerosis surgery.Material and method: Retrospective observational study using our department's otosclerosis database and a validated questionnaire on symptoms associated with the chorda tympani nerve. The sample was divided into two groups: section and conservation (patients whose nerve was anatomically conserved). We studied the presence and duration of symptoms, the surgical technique and the audiometric results.Results: 78 patients (88 ears): section group (18 ears; 20 %) and conservation group (70 ears; 80 %). Overall, gustatory symptoms appear in 35 % (39 % section group; 34 % conservation group). Differences between groups are not statistically significant in relation to presence and duration of symptoms, surgical technique or audiometric results. Only 1 patient in each group reports long-term symptoms. Our results suggest there are no major clinical differences following section versus conservation of the chorda tympani nerve. A wide range of factors such as age, presence of previous middle ear pathology, cross innervation and gastronomic culture may play a role in the appearance of symptoms.Conclusions: Symptoms appearing after iatrogenic damage to the chorda tympani nerve have, in general, little clinical relevance, especially in the long term, regardless of whether the nerve is dissected or manipulated to various degrees.     

Importancia de la cuantificación del desplazamiento hioideo en la valoración del estadio y evolución de la disfagia orofaríngea

Introduction and objectivesThe objective of this paper was to show our experience and considerations when quantifying hyoid bone displacement and to observe its correlation with the qualitative scales that evaluate dysphagia.MethodsHyoid displacement was assessed using the method described by Molfenter and Steele's group in 2014 in a series of 14 patients affected by oropharyngeal dysphagia. The degree of dysphagia was also qualitatively assessed with the Rosenbek Penetration and Aspiration Scale (PAS) of 1996 and with the Functional Oral Intake Scale (FOIS) of Crary of 2005. All assessments were done before and after treatment.ResultsAll patients increased their hyoid bone total displacement after the treatment. These variations were highly correlated with the variations in the PAS scale with aspiration or penetration. However, the variations of hyoid bone displacement did not correlate with the FOIS scale.ConclusionsThe improvement in total hyoid bone displacement is a clinical indicator of improved aspiration of patients suffering dysphagia. However, the improvement of this displacement is not related to the oral intake tolerance of the patients.     

Determinación de pth i en la cirugía del hiperparatiroidismo. nuestra experiencia

Our service of otolaryngology has performed 90 parathyroidectomies at all since april 1990 to 2000 on 92 patients sent to us with diagnosis of hyperparathyroidism. 67 patients were diagnosed as primary hyperparathyroidism; 22 as secondary and 3 cases corresponded to tertiary hyperparathyroidism. we analysed a string of variables before and after the surgery standing out the recent estimate of rapid pth i levels. the kind of surgery we performed was the removal of adenoma in 63 cases; 23 patients were put to subtotal parathyroidectomy and 4 to a total one. an exploratory neck surgery was performed in two patients without finding a parathyroid pathology. we compare the obtained results with other published series and we think it can be useful to determinate the rapid paratohormone levels (pth i) pre and postsurgery (only used in 3 cases by now) in order to predict the clinic response of the patients with hyperparathyroidism     

Recomendaciones de la Guía de Práctica Clínica de la exploración de la vía aérea superior para pacientes adultos con sospecha de síndrome de apnea-hipoapnea obstructiva del sueño (versión reducida)

In November 2014 the Spanish Society of Otolaryngology, the Spanish Sleep Society and the Spanish Society of Maxillofacial Surgery proposed and endorsed the development of a Clinical Practice Guideline on the physical examination of the upper airway in patients with obstructive sleep apnoea.The Guideline strictly followed the recommendations of the manual for the preparation of clinical practice guidelines of the National Health System 2007 and 2009 and the manual of the Scottish Intercollegiate Guidelines Network (SIGN) 2015.The final document could be highly useful for the purposes that were originally proposed: to act as a reference to unify the regions that should be explored in patients with obstructive sleep apnoea-hypopnoea syndrome, the type of examination and how to grade it, and specific to all the care areas to which these patients have access.The conclusions and recommendations are based on a thorough and up-to-date review of the literature with a high level of evidence, as well as the experience and knowledge demonstrated by all the members of the drafting group.This group was formed bearing in mind at all times the transversality of the project, and, therefore, specialists from all the involved areas participated (maxillofacial surgery, family medicine, pneumology, clinical neurophysiology, odontology and otolaryngology). The external reviewers of the final text were selected along the same lines.     

Predicción inmediata de la recuperación del paciente,en función del impacto psicológico del vértigo

Introduction and objectiveThis work presents deeper studies of comorbidity between anxiety and vestibular pathology. The aim of this work was to comprehend the reasons why patients do not feel «fully recovered» even though the treating professionals discharge them. We studied the features of personality that can favour the continuity of the condition.MethodsThe questionnaire for measuring the emotional impact of vertigo makes it possible to determine if the patient has a psychological style with a tendency to develop pathological anxiety levels. Anxiety is a subjective characteristic determinant in difficulties with medical treatment. The questionnaire was applied to 198 patients in Argentina and Mexico in parallel. Each pathology was treated by standard medical procedures. The study focused on determining the correlation between «feeling fully recovered or not at the end of treatment» and the questionnaire scores obtained before the approach.ResultsIn more than 80% of cases, high scores (>15 points) on the questionnaire were correlated with the difficulty presented by the patients for full recovery from the pathology after medical treatment.ConclusionsThe objective assessments (duration and intensity of symptoms, time of onset of the disease, etc.) do not exactly predict possible difficulties during treatment of vertigo. Consequently, we consider the patient's subjective assessment of how the vestibular pathology affects him or her to be determinant. That key information allows us to predict the course of the illness and the probability of a full recovery.     

Reconstrucción de defectos orofaríngeos tras cirugía transoral robótica. Revisión y recomendaciones de la Comisión de Cirugía de Cabeza y Cuello de la Sociedad Española de Otorrinolaringología y Cirugía de Cabeza y Cuello

Transoral surgery of the oropharynx has seen an important evolution in recent years, expanding the surgical options available (TORS, TOUSS, TOLS). The capacity to resect increasingly extensive lesions and the number of patients who benefit from them. This fact has led to an evolution in the reconstruction of surgical defects after transoral surgery. This article aims to review the possible reconstructive techniques, indications and factors to be taken into account prior to surgery, proposing a protocol to assess the need for transoral reconstruction based on the depth of the defect, the staging, and previous treatment.     

Rehabilitación del paciente laringectomizado. Recomendaciones de la Sociedad Española de Otorrinolaringología y Cirugía de Cabeza y Cuello

Total laryngectomy remains essential treatment for locally advanced laryngeal carcinoma, related to better survival rates. However, it involves changes for the patient, such as the inability to communicate verbally, breathing or aesthetic changes, which affect their quality of life and require comprehensive rehabilitation.This paper was written by the total laryngectomy rehabilitation workgroup of the National Head and Neck and Skull Base working committee of the Spanish Society of Otolaryngology and Head and Neck Surgery. The purpose of the article is to combine materials, surgical procedures and means towards the comprehensive rehabilitation of total laryngectomy patients, so that they can achieve a good quality of life. This paper is aimed at all health care professionals caring for total laryngectomy patients. It is also aimed at the patients themselves, as well as ENT surgeons.We have considered staffing and material needs, all procedures before, during and after surgery and after hospital discharge. There are also detailed recommendations about types of rehabilitation and follow-up, and the need for recording these events.The comprehensive rehabilitation total laryngectomy patients is very important if we want to improve their quality of life. The recommendations we mention aim to help the healthcare professionals involved in the treatment of total laryngectomy patients to help them achieve a good quality of life, as similar as possible to the life they led before surgery.     

Significación clínica de la asimetría amigdalina

IntroductionAsymptomatic unilateral tonsillar enlargement is usually treated with systematic tonsillectomy under suspicion of malignancy. Due to the fact that most of the cases are benign pathologies, we set out to study the clinical signs that would help us in the diagnosis in order to avoid unnecessary tonsillectomies.Material and methodsWe reviewed 267 tonsillectomies performed from 1996 to 2006 and 30 of these were indicated because of asymmetry. We evaluated risk factors for malignancy: cervical lymphatic node enlargement, sex, age, tonsillar enlargement noticed by the patient, suspicious appearance, systemic symptoms, history of malignancy and immunocompromise.ResultsHistopathologic study revealed 80 % to be benign and 20 % malignant. The risk factors with the strongest association were enlargement of cervical lymphatic nodes and suspicious appearance of the tonsil.ConclusionsStrict control of a unilateral tonsillar enlargement is possible, but it is mandatory to perform a tonsillectomy when the appearance of the tonsil raises suspicions or there are enlarged lymphatic nodes.     

Evaluación de la vía aérea mediante laringoscopia indirecta en pacientes con hipertrofia de la amígdala lingual

Introduction and objectivesPrevalence of the lingual tonsillar hypertrophy is unknown but it is believed that its presence is associated with the difficult airway. To investigate this, indirect laryngoscopy was performed on patients in the preoperative evaluation and this pathology was diagnosed. The relationship with difficulty of viewing the larynx, intubation and ventilation, under general anaesthesia and using direct laryngoscopy, was then studied.MethodsWe performed the demographic variable checks and tests for predicting difficult intubation (mouth opening, thyromental distance, cervical flexion-extension, neck thickness and Mallampati test), in the preoperative step on 300 patients who were going to be submitted to general anaesthesia. We then performed indirect laryngoscopy on them using a 70° rigid laryngoscope to ascertain the frequency of appearance of lingual tonsillar hypertrophy. Next, under general anaesthesia, we carried out direct laryngoscopy to verify whether there was difficulty in viewing the larynx and intubation and ventilation. We then investigated the association of demographic predictors of difficult intubation, including indirect laryngoscopy, with the presence of this condition.ResultsPrevalence of lingual tonsillar hypertrophy was 2%. No relationship between the appearance of this entity and the difficulty of viewing the larynx, intubation and ventilation was found. Only indirect laryngoscopy was linked to the appearance of this pathology.ConclusionsLingual tonsillar hypertrophy is a relatively frequent disorder, whose presence is not usually associated with difficult airway.     

Monitorización intraoperatoria del nervio facial durante la cirugía de la glándula parótida en servicios de otorrinolaringología - cirugía de cabeza y cuello

IntroductionFacial nerve injury remains the most severe complication of parotid gland surgery. Due to the increasing evidence about the advantage of the use of intraoperative facial nerve monitoring, a survey was distributed among members of the Spanish Society of Otorhinolaryngology-Head and Neck Surgery with the objective of determining patterns of its use.Material and methodsA questionnaire which included 12 separate questions in 3 sections was distributed via email through the official email of the Spanish Society of Otorhinolaryngology-Head and Neck Surgery. The first section of questions was in relation to demographic characteristics, the second section was related to the pattern of monitoring use and the third section referred to litigation related to facial palsy.Results1544 anonymous questionnaires were emailed. 255 surveys were returned, giving an overall response rate of 16.5%. From these, 233 (91.3%) respondents perform parotid gland surgery. Two-hundred nineteen (94%) respondents use intraoperative facial nerve monitoring. Of the respondents,94% used intraoperative facial nerve monitoring if in their current practice they performed fewer than 10 parotidectomies per year and 93.8% if they performed more than 10 (OR, 1.02; 95% CI, 0.68-1.45; p = .991). With regard to lawsuits, just 3 (1.2%) of the respondents had a history of a parotid gland surgery–associated lawsuit and in just one case the facial nerve monitor was not used.ConclusionOur data demonstrate that most otolaryngologists in Spain use intraoperative facial nerve monitoring during parotid gland surgery. Almost all of them use it to improve patient safety and consider that facial nerve monitoring should be helpful preventing inadvertent injury.

Introduction

Total laryngectomy is one of the most mutilating oncological operations. There are no specific studies evaluating return to work after this surgery.

Decanulación y evaluación de la deglución del paciente traqueotomizado en cuidados intensivos no-neurocríticos

With intensive care patients, decannulation and deglutition disorders are frequent reasons for otorhinolaryngological assessment.The objective of a tracheostomy is to maintain a patent airway. It does not necessarily prevent episodes of aspiration and may even favour them. When the cause that led to the tracheostomy resolves, a decannulation may be proposed.Deglutition is a complex act involving the coordinated interaction of several structures of the aerodigestive tract. Fibre-optic endoscopy and videofluoroscopy are 2 useful, complementary tools for the evaluation of patients with swallowing disorders. In managing these patients, a thorough knowledge of laryngeal and swallowing physiology, as well as of the different therapeutic alternatives, is required.Although it is not uncommon for swallowing disorders to coexist in tracheostomy patients, decannulation evaluation is not synonymous with deglutition assessment. A patient could be a candidate for decannulation and have a swallowing disorder, or a tracheostomy patient could swallow adequately.Knowing and understanding these concepts will lead to more efficient management and help to clarify communication between the intensive care physician and the otorhinolaryngologist. Ideally, a multidisciplinary team should be formed to evaluate and manage these patients.     

Validez de las medidas del pico cepstral para la valoración objetiva de la disfonía en sujetos de habla hispana

Introduction and objectivesPerceptual rating of overall voice quality and other more specific perceptual dimensions is difficult, as such judgments depend on the listener's subjectivity. Thus, finding objective, valid, and accessible clinical measures to include in comprehensive voice evaluation protocols is a priority.The purposes of this study were to 1) determine the diagnostic accuracy of a single acoustic measure, smoothed cepstral peak prominence (CPPS), to predict voice disorder status from sustained vowels and connected speech samples using the software Praat; 2) to determine the relationship between measures of CPPS and perceptual ratings of vocal quality; and 3) describe the normative values of CPPS.MethodMeasures of CPPS were obtained from connected speech and sustained vowel recordings of 72 Spanish-speaking subjects with voice disorders and 52 nondysphonic Spanish-speaking subjects with no vocal disorders using freely downloadable Praat software. IBM SPSS Statistics software version 23 was used to complete the statistical analyses.Resultsresults revealed a 70% sensitivity rate, a specificity rate of 85%. Estimated severity for sustained vowels and connected speech were strongly correlated and significantly associated with listener ratings of dysphonia severity.ConclusionsA single acoustic measure of CPPS was highly predictive of voice disorder status using Praat software. Clinicians may consider using CPPS to complement clinical voice evaluation and screening protocols.
