Prophylactic antibiotics in sialendoscopy: a randomized clinical trial.

OBJECTIVE: Antibiotics have been prescribed routinely in sialendoscopy procedures to reduce the risk of postoperative infection, despite the limited evidence supporting this practice. Being necessary to assess the need for antibiotics in Sialendoscopy, aiming to provide evidence-based guidance to clinicians regarding antibiotic administration in this procedure. MATERIALS & METHOD: A prospective, randomized, double-blind, controlled clinical trial to evaluate the of prophylactic antibiotics in Sialendoscopy was designed. RESULTS: A total of 80 patients were included in this study, including 57 females (71.8%) and 23 males (28.8%). In terms of prophylaxis, 36 patients (45%) received prophylactic treatment, and 44 patients (55%) did not. The occurrence of infectious events was observed in 2 patients (5.6%) with prophylaxis and 4 patients (9.1%) without prophylaxis. However, this difference was not statistically significant (p = 0.556). CONCLUSION: In conclusion, our prospective, randomized clinical trial aimed to address the debate regarding the use of prophylactic antibiotics in sialendoscopy. Our study's findings suggest that the routine use antibiotics may not be necessary to prevent postoperative infections in sialendoscopy procedures. These results have important implications for clinical practice, potentially reducing the unnecessary use of antibiotics and addressing concerns related to antibiotic resistance and adverse drug reactions.

Presbiacusia y trastornos del equilibrio en personas mayores. Revision bibliográfica de aspectos etiopatogénicos, consecuencias sobre la calidad de vida y efectos positivos de su tratamiento / Presbycusis and balance disorders in the elderly. Bibliographical review of ethiopathogenic aspects, consequences on quality of life and positive effects of its treatment

A día de hoy, todavía no disponemos de un conocimiento ni una concienciación adecuados sobre las consecuencias que alcanza en la calidad de vida la pérdida de audición en personas mayores. De la misma manera, tampoco existe información suficiente en cuanto a la relación de la presbiacusia y las alteraciones del equilibrio con otras comorbilidades. Dicho conocimiento puede contribuir a mejorar tanto la prevención como el tratamiento de estas patologías, a reducir su impacto en otras áreas como la cognición o la autonomía, así como para poseer una información más certera sobre el impacto económico que generan en la sociedad y en el sistema sanitario.Por ello, con la realización de este artículo de revisión nos planteamos actualizar la información sobre el tipo de hipoacusia y las alteraciones del equilibrio en personas mayores de 55 años, así como sus factores asociados; analizar el impacto que genera en la calidad de vida de estas personas y el que se puede generar a nivel personal y poblacional (tanto en el ámbito sociológico como económico) si se persigue una intervención temprana en estos pacientes.

At this time, we still do not have adequate knowledge and awareness of the consequences of hearing loss in the elderly on quality of life. Similarly, there is also insufficient information on the relationship of presbycusis and balance disorders with other comorbidities. Such knowledge can contribute to improve both prevention and treatment of these pathologies, to reduce their impact on other areas such as cognition or autonomy, as well as to have more accurate information on the economic impact they generate in society and in the health system.Therefore, with this review article we aim to update the information on the type of hearing loss and balance disorders in people over 55 years of age, and their associated factors; to analyze the impact on the quality of life of these people and the one which can be generated at a personal and population level (both sociological and economic) if an early intervention in these patients is pursued.

Parálisis facial: guía de práctica clínica de la Sociedad Española de ORL / Facial paralysis: Clinical practice guideline of the Spanish Society of Otolaryngology

La parálisis de Bell es la forma más común de paresia o parálisis facial. Sin embargo, no todos los pacientes con parálisis facial tienen una parálisis de Bell. Otras causas frecuentes incluyen las secuelas del tratamiento del neurinoma del VIII par, el cáncer de cabeza y cuello, la iatrogenia, el zóster ótico y los traumatismos. El abordaje de cada una de estas situaciones es totalmente diferente. El objetivo de esta guía es servir de consejo para el tratamiento y el seguimiento de los pacientes con parálisis facial. Nuestra idea es que la guía sea práctica, haciendo hincapié en recomendaciones efectivas y útiles en el manejo diario de los pacientes. Esta guía ha sido promovida por la Sociedad Española de ORL y escrita por médicos con experiencia en la enfermedad del nervio facial, incluyendo al menos un especialista de cada comunidad autónoma. Redactada en un formato de preguntas y respuestas, incluye 56 cuestiones relevantes relacionadas con el nervio facial

Bell's palsy is the most common diagnosis associated with facial nerve weakness or paralysis. However, not all patients with facial paresis/paralysis have Bell's palsy. Other common causes include treatment of vestibular schwannoma, head and neck tumours, iatrogenic injuries, Herpes zoster, or trauma. The approach to each of these conditions varies widely. The purpose of this guideline is to provide clinicians with guidance on the treatment and monitoring of patients with different causes of facial paralysis. We intend to draft a practical guideline, focusing on operationalised recommendations deemed to be useful in the daily management of patients. This guideline was promoted by the Spanish Society of Otolaryngology and developed by a group of physicians with an interest in facial nerve disorders, including at least one physician from each Autonomous Community.

Encuesta sobre el conocimiento en la indicación de implantes cocleares para el tratamiento de la hipoacusia en España / Survey on the knowledge of cochlear implant indication in the treatment of hearing loss in Spain

INTRODUCCIÓN: Este trabajo pretende analizar el conocimiento del especialista en Otorrinolaringología en España sobre los criterios de indicación de los implantes cocleares (IC) y, según los resultados, considerar si es necesario implementar medidas de formación dirigidas a mejorar el conocimiento en esta área. MATERIAL Y MÉTODOS: Se diseña un cuestionario dirigido a conocer el nivel de conocimiento sobre la indicación de IC en personas con hipoacusia. Este cuestionario recogía información demográfica de los encuestados y conocimientos sobre aspectos como indicaciones convencionales y emergentes de los IC, características técnicas de los IC y resultados en la población implantada. RESULTADOS: Un total de 222 especialistas españoles en Otorrinolaringología respondieron el cuestionario (10,29% de la muestra encuestada). CONCLUSIONES: Un 50% de los encuestados mostraron unos conocimientos medios-altos sobre IC. Datos epidemiológicos sugieren que un alto porcentaje de adultos con sorderas poslocutivas candidatos a un IC no son referidos para tratamiento. El desconocimiento de los criterios para la indicación de IC por parte de los especialistas en Otorrinolaringología puede contribuir a una inadecuada orientación de los pacientes potencialmente candidatos a un IC. Las mayores deficiencias se encontraron en las indicaciones más emergentes de un IC. Dentro de los profesionales de la Otorrinolaringología los mayores conocimientos sobre IC se concentraron en aquellos que trabajaban en hospitales terciarios, especializados en Otología y Otoneurología, y desempeñaban su actividad laboral en el sector público y privado. Este estudio sugiere la conveniencia de incrementar acciones formativas sobre IC en los profesionales de la Otorrinolaringología, especialmente para otorrinolaringólogos generales

INTRODUCTION: This study aims to analyse the knowledge of cochlear implant (CI) candidacy criteria of otorhinolaryngology specialists in Spain, and from the results, consider whether it is necessary to implement training measures aimed at improving knowledge in this area. MATERIAL AND METHODS: A questionnaire was designed for measuring the level of knowledge of cochlear implant candidacy criteria (CI) in people with hearing loss. The questionnaire collected the demographic data of the respondents and their knowledge on the conventional and emergency indications for CI, technical characteristics of CI and results in the implanted population. RESULTS: A total of 222 Spanish specialists in otorhinolaryngology answered the questionnaire (10.29% of the sample surveyed). CONCLUSIONS: The 50% of all respondents showed a medium-high knowledge about CI. Epidemiological data suggest that a high percentage of adults with postlocutive deafness and candidates for a CI are not referred for treatment. The lack of knowledge about the criteria for the indication of CI by otorhinolaryngology specialists may contribute to inadequate guidance of patients who are potential candidates for CI. The greatest shortcomings are found in the most emergency indications for a CI. Among otorhinolaryngology professionals, the greatest knowledge about CI is found in those who work in tertiary hospitals in the areas of otology and otoneurology, either in the public or private sector. This study suggests that training on CI should be increased for otorhinolaryngology professionals, especially for general otorhinolaryngologists

Designing a Method with Physician Participation to Assess and Improve Quality of Healthcare in Otolaryngology.

OBJECTIVE: Patient choice of healthcare centers to be treated for specific diseases is compromised by the low accessibility of understandable information. Physicians are rarely involved in healthcare quality assessment, despite their potentially valuable input. The purpose of this study was to develop a methodology for evaluating the quality of care that specifically incorporates advice from medical specialists and provides accessible information for patients in search of high-quality healthcare. MATERIALS AND METHODS: A pilot Delphi study was conducted among 28 Spanish otolaryngology experts, seeking their opinion on the quality-of-care indicators and on their ability to recommend the most suitable department for the treatment of specific otolaryngologic diseases. RESULTS: The average acceptance rate was 91.9% for quality-of-care indicator and 96.5% for the resources needed for improving the quality of care. Furthermore, 93% experts reported that patients frequently ask for physician advice on which center provides better care for a specific disease, 92.6% experts believe they could recommend the best centers for specific otolaryngologic diseases, and 80% experts agreed that expert opinion on the quality of care offered by different centers would be a valuable addition to quality-of-care assessment. CONCLUSION: The incorporation of physician advice into healthcare quality assessment may improve the usefulness of healthcare quality indicators for patients. Assessment tools incorporating physician advice should be developed and validated.

Capacidad diagnóstica de la resonancia magnética con técnica de difusión no eco-planar en la detección de colesteatomas primarios y recurrentes / Diagnostic capacity of non-echo planar diffusion-weighted MRI in the detection of primary and recurrent cholesteatoma

Introducción y objetivos: El objetivo de este estudio es determinar la fiabilidad de la resonancia magnética con técnica de difusión no eco-planar en el diagnóstico de pacientes con sospecha clínica de colesteatoma primario y recurrente, evaluando la sensibilidad y especificidad de la prueba en ambos grupos. Métodos: Setenta y cinco pacientes con sospecha clínica de colesteatoma fueron incluidos en el estudio. Cuarenta y ocho pacientes presentaban sospecha clínica de colesteatoma primario y 27 pacientes presentaban sospecha clínica de colesteatoma recurrente. En todos los pacientes se realizó una resonancia magnética con técnica de difusión no eco-planar previa a la cirugía y se compararon los resultados radiológicos con los resultados quirúrgicos obtenidos. Resultados: La sensibilidad, la especificidad, el valor predictivo positivo y el negativo en el grupo de colesteatoma primario fue del 91,2, el 50, el 81,6 y el 70%, respectivamente, y en el grupo de colesteatoma recurrente fue del 100, el 66,7, el 90,9 y el 100, respectivamente. Conclusión: La resonancia magnética con técnica de difusión no eco-planar es una prueba altamente sensible en el diagnóstico del colesteatoma tanto en pacientes con colesteatoma primario como en recurrencias (AU)

Introduction and aims: the aim of this study was to determine the certainty of non-echo-planar imaging diffusion-weighted magnetic resonance imaging (non-EPI DW MRI) in the diagnosis of primary and recurrent cholesteatoma in patients with clinical suspicion of cholesteatoma, assessing the sensitivity and specificity of the test in both groups. Methods: Seventy-five patients with clinical suspicion of cholesteatoma were included in our study. Forty-eight cases had primary suspicion of cholesteatoma and 27 cases had recurrent suspicion of cholesteatoma. All patients received non-EPI DW MRI tests before surgery, and radiological and surgical findings were compared. Results: Sensitivity, specificity and the positive and negative predictive value for primary diagnosis of cholesteatoma group were 91.2%, 50%, 81.6% and 70%, respectively. For the recurrent cholesteatoma group these results were 100%, 66.7%, 90.9% and 100%, respectively. Conclusion: Non-echo-planar imaging diffusion-weighted magnetic resonance imaging is a high sensitivity imaging test for detecting cholesteatoma, for both primary diagnosis and for recurrent cases (AU)

Cochlear implants as a treatment option for unilateral hearing loss, severe tinnitus and hyperacusis.

Tinnitus is an incapacitating condition commonly affecting cochlear implant (CI) candidates. The aim of this clinical study is to assess the long-term effects of CI treatment in patients with severe-to-profound, sensorineural, unilateral hearing loss (UHL) and incapacitating tinnitus. We performed a prospective Cochlear™ company-sponsored multicentre study in five Spanish centres. Sixteen patients with UHL and incapacitating tinnitus, which was indicated by a Tinnitus Handicap Inventory (THI) score >58%, received a Nucleus® CI in their deaf ear. The study design includes repeated within-subject measures on hearing, tinnitus, hyperacusis and quality of life up to 12 months after initial CI fitting. In addition to hearing loss and tinnitus, all patients suffered from hyperacusis. Most patients had a sudden hearing loss and received a CI within 2 years after their hearing loss. Preliminary 6-month, post-CI activation data of 13 subjects showed that the majority of patients perceived a subjective benefit from CI treatment, which was assessed using the THI, a Visual Analogue Scale of tinnitus loudness/annoyance and the Speech, Spatial and Qualities of Hearing Scale. Preliminary 12-month data of 7 subjects showed that most patients also perceived a degree of relief from their hyperacusis. One patient showed no improvements in any of the applied scales, which could be explained by partial insertion of the electrode due to obstruction of the cochlea by otosclerosis. In conclusion, CI can successfully be used in the treatment of UHL patients with accompanying severe tinnitus and hyperacusis. Implantation resulted in hearing benefits and a durable relief from tinnitus and hyperacusis in the majority of patients. These findings support the hypothesis that pathophysiological mechanisms after peripheral sensorineural hearing loss are at least partly reversible when hearing is restored with a CI.

CONCLUSION: Non-echo-planar imaging diffusion-weighted magnetic resonance imaging is a high sensitivity imaging test for detecting cholesteatoma, for both primary diagnosis and for recurrent cases.

Percutaneous onyx embolization of cervical paragangliomas.

Cervical paragangliomas are a group of vascular neoplasms arising from the extraadrenal neuroendocrine system. The present report describes a series of six cases of cervical paragangliomas successfully and safely embolized preoperatively by means of ethylene vinyl alcohol copolymer delivered by percutaneous needle punctures without the need for balloon protection. Although the results are promising, further studies are needed to confirm the superiority of this method versus other embolization techniques and embolic agents.

Clear cell basal cell carcinoma with pulmonary metastasis: case report and literature review.

Clear cell basal cell carcinoma is a rare histological variant of basal cell carcinoma, which has been well described in the literature. We herein report a case of a 56-year-old man who developed lung metastasis from a rather aggressive tumor that grew very rapidly to involve the parotid gland, the mandibular bone, and even the petrous portion of the temporal bone, the middle ear, and the dura mater. Histological diagnosis was clear cell carcinoma, and initially a salivary origin was suspected. Only in the resection specimen, we found areas of more conventional basal cell carcinoma, and final diagnosis was clear cell basal cell carcinoma. We herein report a case of this rare variant and comment on the histopathological differential diagnosis and the possible relation between these tumors and Gorlin-Goltz syndrome.

International consensus on Vibrant Soundbridge® implantation in children and adolescents.

OBJECTIVE: Active middle ear implants augment hearing in patients with sensorineural, conductive, and mixed hearing losses with great success. However, the application of active middle ear implants has been restricted to compromised ears in adults only. Recently, active middle ear implants have been successfully implanted in patients younger than 18 years of age with all types of hearing losses. The Vibrant Soundbridge (VSB) active middle ear implant has been implanted in more than 60 children and adolescents worldwide by the end of 2008. In October 2008, experts from the field with experience in this population met to discuss VSB implantation in patients below the age of 18. METHODS: A consensus meeting was organized including a presentation session of cases from worldwide centers and a discussion session in which implantation, precautions, and alternative means of hearing augmentation were discussed. At the end of the meeting, a consensus statement was written by the participating experts. The present consensus paper describes the outcomes and medical/surgical complications: the outcomes are favourable in terms of hearing thresholds, speech intelligibility in quiet and in noise, with a low incidence of intra- and postoperative complications. CONCLUSIONS: Taken together, the VSB offers another viable treatment for children and adolescents with compromised hearing. However, other treatment options should also be taken into consideration. The advantages and disadvantages of all possible treatment options should be weighed against each other in the light of each individual case to provide the best solution; counseling should include a.o. surgical issues and MRI compatibility.

Time course of episodes of definitive vertigo in Meniere's disease.

OBJECTIVE: To evaluate the frequency and duration of episodes of definitive vertigo in Ménière's disease. DESIGN: Prospective longitudinal study. SETTING: Multiple tertiary referral centers. PATIENTS: Five hundred ten individuals from 8 hospitals that met the American Academy of Otolaryngology-Head and Neck Surgery diagnostic criteria for definitive Ménière's disease. INTERVENTION: Conservative treatment. MAIN OUTCOME MEASURE: Frequency and duration of episodes of definitive vertigo during follow-up. RESULTS: Ménière's disease affects both sexes and both ears equally, with onset generally in the fourth decade of life. The number of episodes of vertigo is greater in the first few years of the disease. Although episodes of vertigo that last longer than 6 hours are less frequent than shorter episodes, they occur with similar frequency throughout the natural course of the disease. The percentage of patients without episodes of vertigo increases as the disease progresses, and 70% of patients who did not have an episode of vertigo for 1 year will continue to be free of episodes during the following year. Thus, there is a relationship between the frequency of episodes in consecutive years, although this association decreases rapidly as the number of years increases. CONCLUSION: The frequency of definitive episodes of vertigo in Ménière's disease decreased during follow-up, and many individuals reached a steady-state phase free of vertigo.

Adherence of Streptococcus pneumoniae to polystyrene plates, effect of serum on adhesion, and virulence in the gerbil otitis media model.

The adherence of 11 pneumococcal strains to polystyrene was studied and expressed as the number of colony-forming units (CFU) recovered per 10(6)CFU of initial inoculum. Three strains were considered as strong adherent (>100CFU/10(6)), three as medium adherent (10-100CFU/10(6)), and five as low adherent (<10CFU/10(6)). All serotype 3 strains were low adherent whilst serotypes 23F and 19F behaved as strong or medium adherent. The impact of gerbil sera on adherence of six selected pneumococcal strains (one strong adherent, one medium adherent, and four low adherents) to abiotic material was also studied under two experimental conditions. In the presence of sera, the adherence ability of the strong, medium, and one low adherent strains decreased significantly. On the other hand, the adherence significantly increased in all strains when sera were removed following preincubation of bacteria exposed to sera, although such increase was statistically significant for five of them. Finally, the ability of two (one strong adherent and one low adherent) strains to induce otitis media in gerbils was also evaluated; the strong adherent strain behaved significantly more virulent than the less adherent in terms of ear damage and animal weight loss.
