Proposal of standardization of Horus® computerized posturography in adults.

PURPOSE: To propose a normalization model of a posturography platform in adults without changes in body balance, through descriptive analysis by age group and sex. METHODS: Cross-sectional observational study. Adults, with no changes in body balance and no vestibular complaints were submitted to 6 sensory conditions on the Horus® posturography platform. The following variables were analyzed: stability limit area and confidence ellipse area, trajectory length and average velocity for each condition tested. The variables were analyzed by age group and sex. The equilibrium score, the sensory integration test and the equilibrium index were calculated on the conditions. RESULTS: Sixty-one subjects (38.3%) and 23 (37.7%) were male, 40 (65.57%) between the ages of 20 and 40 and 21 (34.43). %) between 41 and 59 years. The area of the stability limit and pressure center variables for 6 sensory conditions tested - confidence ellipse area, trajectory length, total mean velocity and confidence ellipse ratio by the area of the stability limit were described. There was a statistically significant difference in the comparison between the area of the stability limit between sexes and between age groups, being a higher value in males and in younger patients. Regarding the analysis of the variables by each condition, there was no difference of results between the sexes and age groups. CONCLUSION: Subjects of different sexes and age groups should be considered separately only in the analysis of the stability limit.

HiFocus Helix™ electrode insertion: surgical approach.

BACKGROUND: Cochlear implants have been used for almost 30 years as a device for the rehabilitation of individuals with severe-to-profound hearing loss. One of the important aspects of cochlear implantation is the type of electrode selected and proper insertion of the electrode array in scala tympani to minimize cochlear damage. The HiFocus Helix™ electrode is a precurved design aimed at placing the electrode contacts close to the spiral ganglion cells in the modiolus. The prescribed insertion techniques are intended to minimize the likelihood of damage to the basilar membrane or lateral wall of the cochlea. CASE PRESENTATION: To describe the first insertion of a HiFocus Helix™ electrode in Brazil exposing surgical particularities and device details in a patient with profound hearing loss, due to Mondini's dysplasia. CONCLUSION: No problems were encountered during the surgical procedure. The patient experienced improvement in hearing thresholds and speech perception. The HiFocus Helix™ electrode proved easy to insert and provided expected hearing benefits for the patient. This manuscript indicates that the HiResolution™ Bionic Ear System with HiFocus Helix™ electrode comprise a cochlear implant system that is practical and beneficial for the treatment of severe-to-profound hearing loss.

Stapedial reflex and recruitment: what is the relationship with tinnitus?

Tinnitus is characterized by an auditory perception of sound, with no stimuli from the external environment. Tinnitus is an increasingly significant complaint, affecting 10-17% of the world population. As a symptom, it should always be considered with pathology in the auditory system. Our study aims to assess the relationship of this symptom with the presence of a stapedial reflex and the phenomenon of recruitment. Medical records of patients complaining of subjective tinnitus during their first consultation in the Outpatient Clinic of the Unicamp Teaching Hospital, in Brazil, between 2011 and 2012 were analyzed. We carried out a study with 65 non-randomized tinnitus individuals using questionnaires, clinical and audiological evaluations. The visual analogue scale was used to characterize the degree of disturbance caused by tinnitus. Statistical tests were performed using the IBM SPSS Statistics 19. No association was found between tinnitus and the presence of acoustic reflex or phenomenon of recruitment. We concluded that there is no relationship between tinnitus, the phenomenon of recruitment or the presence of an acoustic reflex.

Endoscopic endonasal transsphenoidal resection of pituitary adenomas: preliminary evaluation of consecutive cases.

INTRODUCTION: Endoscopic endonasal transsphenoidal surgery has gained increasing acceptance by otolaryngologists and neurosurgeons. In many centers throughout the world, this technique is now routinely used for the same indications as conventional microsurgical technique for pituitary tumors. OBJECTIVE: To present a surgical experience of consecutive endoscopic endonasal trans-sphenoidal resections of pituitary adenomas. METHODS: In this study, consecutive patients with pituitary adenomas submitted to endoscopic endonasal pituitary surgery were evaluated regarding the rate of residual tumor, functional remission, symptoms relief, complications, and tumor size. RESULTS: Forty-seven consecutive patients were evaluated; 17 had functioning adenomas, seven had GH producing tumors, five had Cushing's disease, and five had prolactinomas. Of the functioning adenomas, 12 were macroadenomas and five were microadenomas; 30 cases were non-functioning macroadenomas. Of the patients with functioning adenomas, 87% improved. 85% of the patients with visual deficits related to optic nerve compression progressed over time. Most of the patients with complaints of headaches improved (76%). Surgical complications occurred in 10% of patients, which included with two carotid lesions, two cerebrospinal fluid leaks, and one death of a patient with a previous history of complications. CONCLUSION: Endoscopic endonasal pituitary surgery is a feasible technique, yielding good surgical and functional outcomes, and low morbidity.

Study of the relationship between the degree of tinnitus annoyance and the presence of hyperacusis.

INTRODUCTION: Hyperacusis can be defined as a manifestation of an increased of central auditory pathways gain and can be considered a pre-tinnitus state. In some cases tinnitus can be caused by such increased gain. AIM: To evaluate the prevalence of hyperacusis in patients with tinnitus and its relation to the annoyance of tinnitus. MATERIALS AND METHODS: Retrospective study with patients from the neurotology service complaining of tinnitus in the first consultation were submitted to clinical evaluation, a questionnaire and audiological evaluation of tinnitus and hyperacusis. The degree of annoyance of tinnitus and hyperacusis was measured using a visual analog scale. RESULTS: We analyzed medical records of 309 patients, 169 (54.7%) females and 140 (45.3%) males. The mean age was 53 years. The median degree of tinnitus annoyance was 7. Hyperacusis was present in 57 (18.4%) patients, with a median degree of 5. The degree of annoyance due to tinnitus patients with hyperacusis was similar to that of patients without hyperacusis. CONCLUSION: Hyperacusis was present in 18.4% of patients with tinnitus. The degree of annoyance due to tinnitus had no correlation with the presence of hyperacusis.

Correlation of cephalometric and anthropometric measures with obstructive sleep apnea severity

Patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) often have associated changes in craniofacial morphology and distribution of body fat, either alone or in combination. AIM: To correlate cephalometric and anthropometric measures with OSAHS severity by using the apnea-hypopnea index (AHI). METHOD: A retrospective cephalometry study of 93 patients with OSAHS was conducted from July 2010 to July 2012. The following measurements were evaluated: body mass index (BMI), neck circumference (NC), waist circumference (WC), hip circumference (HC), the angles formed by the cranial base and the maxilla (SNA) and the mandible (SNB), the difference between SNA and SNB (ANB), the distance from the mandibular plane to the hyoid bone (MP-H), the space between the base of the tongue and the posterior pharyngeal wall (PAS), and the distance between the posterior nasal spine and the tip of the uvula (PNS-P). Means, standard deviations, and Pearson's correlation coefficients were calculated and analyzed. RESULTS: AHI correlated significantly with BMI (r = 0.207, p = 0.047), NC (r = 0.365, p = 0.000), WC (r = 0.337, p = 0.001), PNS-P (r = 0.282, p = 0.006), and MP-H (r = 0.235, p = 0.023). CONCLUSION: Anthropometric measurements (BMI, NC, and WC) and cephalometric measurements (MP-H and PNS-P) can be used as predictors of OSAHS severity...

(Central) auditory processing: the impact of otitis media.

OBJECTIVE: To analyze auditory processing test results in children suffering from otitis media in their first five years of age, considering their age. Furthermore, to classify central auditory processing test findings regarding the hearing skills evaluated. METHODS: A total of 109 students between 8 and 12 years old were divided into three groups. The control group consisted of 40 students from public school without a history of otitis media. Experimental group I consisted of 39 students from public schools and experimental group II consisted of 30 students from private schools; students in both groups suffered from secretory otitis media in their first five years of age and underwent surgery for placement of bilateral ventilation tubes. The individuals underwent complete audiological evaluation and assessment by Auditory Processing tests. RESULTS: The left ear showed significantly worse performance when compared to the right ear in the dichotic digits test and pitch pattern sequence test. The students from the experimental groups showed worse performance when compared to the control group in the dichotic digits test and gaps-in-noise. Children from experimental group I had significantly lower results on the dichotic digits and gaps-in-noise tests compared with experimental group II. The hearing skills that were altered were temporal resolution and figure-ground perception. CONCLUSION: Children who suffered from secretory otitis media in their first five years and who underwent surgery for placement of bilateral ventilation tubes showed worse performance in auditory abilities, and children from public schools had worse results on auditory processing tests compared with students from private schools.

Mensuração da evolução terapêutica com paquímetro digital na Paralisia Facial Periférica de Bell / Measurement of evolution therapy using a digital caliper in Palsy Bell

OBJETIVO: avaliar o uso do paquímetro digital na mensuração dos movimentos da mímica facial em diferentes momentos do tratamento fonoaudiológico. MÉTODO: estudo longitudinal prospectivo, em 20 sujeitos com idade entre 07 e 70 anos, sendo 13 do genero feminino e 07 masculino, com diagnóstico de paralisia facial periférica de Bell, atendidos no Ambulatório de Paralisia Facial, da disciplina de otorrinolaringologia de um Hospital Público Universitário. Neste estudo foi adotado o uso de um medidor paquímetro digital da marca Digimess 100.174BL, instrumento com resolução de 0,00mm/152,78mm. As medições foram realizadas no movimento da mímica facial, sempre partindo de um ponto fixo para o ponto móvel nas estruturas: tragus e comissura labial, canto externo do olho e comissura labial e também canto interno do olho e asa do nariz, sendo realizadas pré e pós tratamento fonoaudiológico. A quantificação da incompetência do movimento foi mensurada por meio de porcentagem simples. Foi aplicado teste dos Postos Sinalizados de Wilcoxon, para verificar possíveis diferenças entre ambos os momentos considerados (com e sem movimentos), como as variáveis de interesse. RESULTADOS: as mensurações tiveram um resultado estatisticamente significante (p<0,05) em todas as estruturas medidas propostas (tragus e comissura labial, canto externo do olho e comissura labial e canto interno do olho e asa do nariz), demonstrando que há possibilidades de se fazer medições de movimento e de ausência de movimento utilizando o paquímetro digital. CONCLUSÃO: o paquímetro mostrou ser um instrumento útil que permitiu comparar, de forma objetiva, a evolução da reabilitação da mímica facial na Paralisia Facial Periférica de Bell na amostra estudada.

PURPOSE: to assess the use of the digital caliper in the measurement of the facial mimic movements in different moments of the speech therapy. METHOD: prospective longitudinal study, with 20 subjects between 7 and 70 years-old, 13 females and 7 males, all diagnosed with Bell’s Palsy, attended in the Facial Paralysis Ambulatory, of the otorhinolaryngology subject of a University Public Hospital. The use of a Digimess 100,174BL digital measuring caliper was adopted for this study. The measurements were carried out in the facial mimic movement, always starting from a fixed point to a mobile point in the structures: the tragus and the labial commissure, external corner of the eye and labial commissure and also internal corner of the eye and the nasal ala. All measurements were carried out both prior and after the treatment. The quantification of the incompetence of the movement was measured by simple percentage. The Wilcoxon signed rank test was applied to check for possible differences between both moments considered (with and without movements), as the study variables. RESULTS: the measurements had a statistically significant result (p<0.05) in all the proposed measured structures (tragus and labial commissure, external corner of the eye and labial commissure, and internal corner of the eye and nasal ala), showing that there are possibilities of measuring of movement and absence of movement using a digital caliper. CONCLUSION: the caliper has demonstrated to be a useful device which has permitted to objectively compare the evolution of the rehabilitation of facial mimic in Bell’s Palsy in the sample studied here.

Mastigação, deglutição e suas adaptações na paralisia facial periférica / Mastication, deglutition and its adaptations in facial peripheral paralysis

OBJETIVO: caracterizar mastigação, fase oral da deglutição e possíveis adaptações funcionais observadas nos portadores de Paralisia Facial Periférica. MÉTODO: participaram desta pesquisa 30 indivíduos com Paralisia Facial Periférica grau IV, com história de até 30 dias, sem distinção de etiologia e divididos em três grupos, os que apresentavam a paralisia em até 10 dias, de 11 a 20 e de 20 a 30 dias. As funções mastigação e fase oral da deglutição foram avaliadas tanto com alimento sólido e como com água natural. Os indivíduos responderam questões relacionadas às dificuldades imediatamente após a instalação da paralisia. Os dados foram analisados estatisticamente pelo Teste da Razão de Verossimilhança e pelo Teste Exato de Fisher. RESULTADOS: foram constatadas alterações nas funções de mastigação e fase oral da deglutição pela diminuição do tônus no músculo orbicular dos lábios e do músculo bucinador, que diminuindo a pressão intra-oral, favorece o escape de alimento e líquido. À observação da Fonoaudióloga a variável "derrama líquido enquanto bebe" apresentou dados estatisticamente significante (p=0,003) nos três grupos estudados. A variável "acúmulo de alimento entre os dentes e a gengiva no lado paralisado" foi estatisticamente significante nos grupos de 11 a 20 dias (p= 0,002). CONCLUSÃO: os indivíduos da amostra mastigam no lado paralisado com dificuldade, mediante ciclos mastigatórios lentos e inconsistentes. Ocorre um incremento nos movimentos de língua para limpeza de resíduos retidos no vestíbulo oral no lado paralisado. Este é o sintoma que mais incomoda o paciente. Apresentam dificuldade no beber de forma contínua. Desenvolvem adaptações para compensar suas dificuldades funcionais.

PURPOSE: to describe mastication, swallowing oral phase and possible functional adaptations observed in Facial Peripheral Paralysis subjects. METHOD: there were 30 subjects with grade IV Facial Peripheral Paralysis, with at the most 30 days paralysis history and no etiology differentiation. They were separated in three groups, 1 to 10 days paralysis, 11 to 20 days and 21 to 30 days. Mastication and swallowing oral phase functions were assessed with both solid food and water. Participants answered questions related to the difficulties right after the paralysis. Data were statistically analyzed using the Likelihood Ratio Test and Fisher Exact Test. RESULTS: changes were observed in mastication and swallowing oral phase due to the lowering of lips tonus, orbicular muscle and buccinator muscle that allows the escaping of food and liquid by decreasing intra-oral pressure. To the speech therapist's observation "spill liquid while drinking" presented statistically significant data (p=0,003) in the three observed groups. Variable "accumulate food between teeth and gums" was statistically significant in groups of 11 to 20 days (p= 0,002). CONCLUSION: sample subjects chew with difficulty in the paralyzed side, showing slow and inconsistent mastication cycles. There is an increased tongue movements for cleaning the residues kept in oral vestibule in the paralyzed side. This is the most annoying symptom according to the patients. They develop adaptation strategies to compensate their functional difficulties.

Correlation of cephalometric and anthropometric measures with obstructive sleep apnea severity.

INTRODUCTION: Patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) often have associated changes in craniofacial morphology and distribution of body fat, either alone or in combination. AIM: To correlate cephalometric and anthropometric measures with OSAHS severity by using the apnea-hypopnea index (AHI). METHOD: A retrospective cephalometry study of 93 patients with OSAHS was conducted from July 2010 to July 2012. The following measurements were evaluated: body mass index (BMI), neck circumference (NC), waist circumference (WC), hip circumference (HC), the angles formed by the cranial base and the maxilla (SNA) and the mandible (SNB), the difference between SNA and SNB (ANB), the distance from the mandibular plane to the hyoid bone (MP-H), the space between the base of the tongue and the posterior pharyngeal wall (PAS), and the distance between the posterior nasal spine and the tip of the uvula (PNS-P). Means, standard deviations, and Pearson's correlation coefficients were calculated and analyzed. RESULTS: AHI correlated significantly with BMI (r = 0.207, p = 0.047), NC (r = 0.365, p = 0.000), WC (r = 0.337, p = 0.001), PNS-P (r = 0.282, p = 0.006), and MP-H (r = 0.235, p = 0.023). CONCLUSION: Anthropometric measurements (BMI, NC, and WC) and cephalometric measurements (MP-H and PNS-P) can be used as predictors of OSAHS severity.

Avaliação do implante coclear Digisonic® SP: evolução dos pacientes e sistema de fixação com parafusos de titânio / Evaluation of the Digisonic® SP cochlear implant: patient outcomes and fixation system with titanium screws

O implante coclear para pacientes com disacusia grave/profunda revolucionou o modo com que estes interagem com o meio ambiente. A Neurelec desenvolveu um sistema que permite fixação com uso de dois simples parafusos de titânio, sem necessidade de broqueamento do osso do crânio do paciente. Este artigo teve o objetivo de descrever uma casuística de pacientes submetidos a implante coclear com o Digisonic® SP, para mostrar os resultados cirúrgicos e detalhes do procedimento. MÉTODO: Estudo retrospectivo que avaliou os pacientes, no período de 18 meses, submetidos a implante coclear com o Digisonic® SP. Todos os pacientes eram pós-linguais. Coleta dos dados realizada por meio da análise dos prontuários dos pacientes, além de questionário padronizado aplicado nos cirurgiões que realizaram o procedimento. RESULTADOS: Os seis casos implantados com o Digisonic® SP foram realizados por cirurgiões experientes e o tempo cirúrgico variou de 95 a 203 minutos (média de 135 minutos), que é menor do que o descrito com outras formas de fixação. Não houve nenhum tipo de complicação e o ganho auditivo foi satisfatório. CONCLUSÃO: O implante Digisonic® SP desenvolvido pela Neurelec apresentou bons resultados audiológicos em adultos, tempo de cirurgia menor e não ocorreram complicações cirúrgicas ou pós-operatórias.

Cochlear implants have revolutionized the way patients affected by severe hearing loss experience the world. Neurelec developed a fixation system with two titanium screws that requires no skull bone drilling. OBJECTIVE: To describe the outcomes and procedure-related details of a series of patients implanted with the Digisonic® SP cochlear implant. METHOD: This retrospective study analyzed patients submitted to cochlear implant placement within a period of 18 months. All patients had postlingual hearing impairment. Data was collected from patient charts and standard questionnaires answered by the surgeons in charge of carrying out the procedures. RESULTS: The six patients offered the Digisonic® SP cochlear implants were operated by experienced surgeons. The procedures took 95 to 203 minutes (mean = 135') to be completed, which is less time than what has been described for other fixation approaches. No complications were recorded and hearing improvement was satisfactory. CONCLUSION: The Digisonic® SP cochlear implant developed by Neurelec offered good audiological results for adult patients, shorter surgery time, and no surgical or postoperative complications.
