RESUMO

BACKGROUND: Endoscopes provide a magnified view of the middle ear and visualisation of hidden areas. Otoendoscopes facilitate excellent visualisation of the round window niche during cochlear implantation. OBJECTIVE: To compare microscopic and endoscopic visualisation of the round window membrane during cochlear implantation in 20 patients. METHODS: Twenty patients who underwent cochlear implantation were included in the study. After maximum exposure of the round window, the accessibility of the round window membrane was graded according to the St Thomas Hospital classification, first by microscope and then by endoscope. RESULTS: With the use of the endoscope, visualisation of the round window membrane improved in all the patients as compared to the microscope. The electrode array was inserted via a round window or extended round window approach in all but two cases; the latter cases required bony cochleostomy because of unfavourable anatomy. CONCLUSION: The main benefit of endoscope-assisted cochlear implantation is improved visibility of the round window region.

RESUMO

INTRODUCTION: The field of otolaryngology, head and neck surgery faces a wide range of medical conditions, starting with upper airway morbidity, head and neck tumors, hearing loss and deafness, ear diseases, nose, sinuses, and anterior skull base conditions, pediatric otolaryngology, laryngology and facial and reconstructive plastic surgery. The current issue of this journal presents a variety of manuscripts that are in the forefront of our specialty in Israel and around the world. The management of laryngeal tumors is undergoing thorough modification aiming to preserve the organ while early tumors are treated endoscopically using laser technology. The human papilloma virus is one of the major changes that recently emerged as an important etiologic factor for oropharyngeal carcinoma in young nonsmokers. Hearing loss and deafness are negative contributors to the quality of life. Congenital hearing loss has a major effect on brain development, and speech and language development, therefore, early cochlear implantation is beneficial for well child development. Different aspects associated with cochlear implantation are discussed in this issue. Many fields that are associated with our specialty are gradually utilized by otolaryngologists, for example the utilization of ultrasound by surgeons. The field of otolaryngology head and neck surgery is dynamic and abundant with innovative technologies that are presented in this article, starting with cochlear implants, robotic surgery, and the utilization of 3D printers for complicated facial reconstructions. We are in the midst of a journey and we may assume that the future holds great promise both for our patients and for us as health care providers.

RESUMO

BACKGROUND: After cochlear implantation (CI) there is concern regarding the potential risks of spread of middle ear infection along the electrode array into the cochlea and central nervous system and regarding late sequela of otitis media (OM): eardrum perforation, atelectasis and cholesteatoma. The age for implantation in children overlaps the peak age incidence of acute OM (AOM) and secretory OM (SOM) and delay of implantation reduces the potential benefit from the intervention. Therefore, control of OM by inserting ventilating tubes (VT) is widely performed in pediatric CI candidates who also suffer from otitis media. OBJECTIVES: To refine indications for VT insertion in candidates for cochlear implantation who also suffer from OM. METHODS: Of 200 children referred for CI and implanted one after another, 126 were classified as OM-prone, 98 due to AOM and 28 due to SOM. The rate of development of late sequela of middle ear disease was compared between the two subgroups of OM-proneness. RESULTS: A total of 15 children (7.5%) developed late sequela of middle ear disease; all belonged to the SOM group; 3.5% developed eardrum perforation; 3.5% atelectasis and 0.5% cholesteatoma. CONCLUSIONS: Pre-CI VT insertion in children with SOM who underwent CI did not prevent development of late sequela of middle ear disease; VT insertion with the object of preventing late sequela of middle ear disease in CI candidates who suffer from SOM only is not required; in otitis-prone children a long term oto-microscopic follow-up is needed in order to identify late sequela of middle ear disease.

RESUMO

INTRODUCTION: In normal hearing, the brain receives bilateral auditory input from both ears. In individuals with only one functioning ear listening in noisy environments and sound localization may become difficult. Historically, the impact of unilateral hearing loss in children had typically been minimized by clinicians, as it was assumed that one normal hearing ear provided sufficient auditory input for speech development and normal hearing experience. Data supporting the negative effects of unilateral deafness has been accumulating during the last decades. The effects of unilateral deafness extend beyond spatial hearing to language development, slower rates of educational progress, problems in social interaction and in cognitively demanding tasks. Until recently, treatments for single sided deafness were limited to routing signals from the deaf ear to the contralateral hearing ear either through conventional CROS aids or through bone anchored technologies. These technologies simply transfer sounds to the single functioning ear which allow sound awareness from the deaf side and minor improvement in hearing in noisy environments and localization. The cochlear implant is a surgically implanted electronic device that contains an array of electrodes which is placed into the cochlea, and stimulates the cochlear nerve. The cochlear implant bypasses the injured parts of the inner ear. Currently it is the only treatment to restore binaural hearing. This review aims to discuss the different aspects, the benefits and disadvantages of cochlear implantation in children with single sided deafness.

RESUMO

Background - Several cochlear implant recipients experience functionality loss due to electrode array mal-positioning. The application of delicate perimodiolar electrodes has many electrophysiological advantages, however, these profiles may be more susceptible to tip fold-over. Purpose - The prompt realization of such complication following electrode insertion would be auspicious, thus the electrode could be possibly repositioned during the same surgical procedure. Methods - The authors present three tip fold-over cases, experienced throughout their work with Slim Modiolar Electrode implants. Implantations were performed through the round window approach, by a skilled surgeon. Standard intraoperative measurements (electric integrity, neural response telemetry, and electrical stapedial reflex threshold tests) were successfully completed. The electrode position was controlled by conventional radiography on the first postoperative day. Results - Tip fold-over was not tactilely sensated by the surgeon. Our subjects revealed normal intraoperative telemetry measurements, only the postoperative imaging showed the tip fold-over. Due to the emerging adverse perception of constant beeping noise, the device was replaced by a CI512 implant after 6 months in one case. In the two remaining cases, the electrode array was reloaded into a back-up sheath, and reinserted into the scala tympani successfully through an extended round window approach. Discussion - Future additional studies using the spread of excitation or electric field imaging may improve test reliability. As all of these measurements are still carried out following electrode insertion, real-time identification, unfortunately, remains questionable. Conclusion - Tip fold-over could be reliably identified by conventional X-ray imaging. By contrast, intraoperative electrophysiology was not sufficiently sensitive to reveal it.

RESUMO

OBJECTIVE: To report the rate of major soft tissue complications after cochlear implantation and to describe the use of the temporoparietal fascia (TPF) flap for such complications. STUDY DESIGN: Retrospective case series. SETTING: Tertiary care, University Hospital. SUBJECTS AND METHODS: Chart review of all patients who underwent cochlear device implantation over a 5-year period to identify patients and to determine the rate of soft tissue complications. Five patients with major soft tissue complications underwent TPF flap with device salvage or explantation/reimplantation. RESULTS: The rate of major skin complications was 6 out of 281 (2.1%) over 5 years, with 5 patients undergoing TPF flap. The average follow-up was 25.8 months (range, 5-58 months). TPF flap represented the definitive, successful solution for all 5 patients. One postoperative hematoma occurred after TPF flap, with no long-term sequelae. The average hospital length of stay was 2.2 nights (range, 1-5 nights). One patient required IV antibiotics for 4 weeks; the remaining patients were treated with a postoperative course of oral antibiotics. The original device remained in place for 4 patients, while one case required device explantation and staged re-implantation. Post-TPF flap hearing results were equal to if not superior to their preoperative results. CONCLUSION: Major soft tissue complications following cochlear device implantation are rare. The temporoparietal fascia flap is an excellent option for reconstruction of device site soft tissue dehiscences when local wound care and primary closure are not sufficient, and can potentially prevent explantation of a functional implant.

RESUMO

In this article, we consider the influence of combined general anesthesia on the results of electrically-involved stapedial reflex threshold (esrt) registration. We pay a special attention to the anesthesia to exclude its influence on the esrt. This study included 52 patients with bilateral chronic neurosensory hearing impairment. We conducted a retrospective (from 2014 to 2016) and prospective (from 2017 to 2018) analysis of anesthesia protocols. Even though the inhaled anesthesia (sevoflurane in this case) has a depressive effect on esrt registration (the higher the minimal alveolar concentration of anesthetic agent, the higher the reflex threshold), our study shows a possibility of using it in an extended anesthesia monitoring. Inclusion of myorelaxants in cochlear implantation anesthesia protocol not only provides a safe anesthesia, but also does not prevent a timely intraoperative cochlear implant testing.

RESUMO

RATIONALE: Cochlear implantation (CI) in CHARGE syndrome is technically challenging because of the anatomical anomalies. This case aims to report a successful case of CI in CHARGE syndrome by using the modified transcanal approach with external auditory canal (EAC) obliteration. PATIENT CONCERNS: The 3-year-old girl presented at the outpatient department with bilateral hearing loss and nasal obstruction since birth. DIAGNOSIS: The patient had bilateral profound sensorineural hearing loss, patent ductus arteriosus, atresia of the choanae, middle and inner ear anomalies, and growth retardation, fulfilling the criteria for typical CHARGE syndrome. High resolution temporal bone computed tomography scan revealed a poorly developed mastoid cavity, cochlear dysplasia, hypoplastic semicircular canals, ossicular chain malformation, and sigmoid sinus engorgement. Magnetic resonance imaging revealed a narrow internal auditory canal and a hypoplastic cochlear nerve. INTERVENTIONS: Modified transcanal approach with external auditory canal obliteration OUTCOMES:: CI was successfully done and there are no intraoperative or postoperative complications occurred after 1 year of follow up. LESSONS: The modified transcanal approach is a reasonable and safer option for CI in CHARGE syndrome.

RESUMO

Streptococcus pneumoniae is a major cause of bacterial meningitis in children. It can progress and carries a serious risk of mortality and morbidity despite effective treatment. Cochlear implantation is a fairly successful procedure for restoring hearing in cases of sensorineural hearing loss. Moreover, patients with cochlear implants are at increased risk of contracting pneumococcal meningitis compared to the general population. The development of meningitis is associated with pathogens in the middle ear that contaminate the cerebrospinal fluid (CSF), as a result of congenital anomalies in the cochlea, and the cochlear implant. A 4-year-old girl presented to our clinic with fever, vomiting, and weakness. A physical examination showed an axillary temperature of 38.3°C, heart rate of 134/min, respiration rate of 50 breaths/minute, and arterial blood pressure of 120/88 mmHg. The patient also had a neck stiffness and her Kernig and Brudzinski signs were positive. It was discovered that the patient had undergone cochlear implantation approximately five months prior due to bilateral congenital sensorineural hearing loss. She had also received the Haemophilus influenzae type b and PCV-13 vaccines in line with the national immunization calendar. Her laboratory findings showed a leukocyte count of 21.900/mm3 (neutrophils 90% and lymphocytes 10%) and her procalcitonin level was 1.22 ng/ml. An uncountable number of neutrophils was identified in her cerebrospinal fluid, which led to the initial diagnosis of meningitis. There was also 1 mg/dl of glucose (blood glucose, 102 mg/dl) and 706 mg/dl of protein in her cerebrospinal fluid. Empirically, vancomycin (60 mg/kg/day) and ceftriaxone (100 mg/kg/day) were started. Following 5 days of antibiotic treatment, penicillin-susceptible S.pneumoniae was yielded in her CSF culture and identified as serotype 24B. S.pneumoniae with the same antibiotic sensitivity was also identified in her blood culture. Since rhinorrhea was observed on day 16 of hospitalization, she underwent an operation to repair the fistula tract. A computerized tomography cranial scan was performed after the development of acute mental fog at postoperative day 3 and showed brain edema and a thrombus in the right middle cerebral artery. The patient died on day 42 of hospitalization due to multiple organ failure. To our knowledge, this is the first case of meningitis reported in our country associated with S.pneumoniae serotype 24B in a patient with a cochlear implant. While there has been a decrease in the prevalence of invasive pneumococcal disease with routine administration of the pneumococcal conjugate vaccine, a relative increase has been observed in its non-vaccine serotypes. This is relevant not only to patients with more risk factors, such as a cochlear implant, but also those who are at lower risk for pneumococcal infection.

RESUMO

The association between deafness and visual disorders is frequent. These disorders range from simple refractive disorder to severe disease that can lead to disability. Hence the interest of early screening. This study aims to highlight the importance of multidisciplinary management and of the need for ophthalmological examination in each deaf child. We conducted a prospective monocentric data collection from medical records of 200 children followed for hypoacousia from January 2014 to January 2015. Each child underwent complete ophthalmological examination, ENT examination and clinical examination. Data from 155 medical records were collected. Ocular involvement was found in 47 patients, reflecting a rate of 30.4%. Bilateral involvement was found in 45 patients. The main syndromic causes were: Usher syndrome (8 casess), Waardenbourg syndrome (5 cases), Alport syndrome (3 cases), Wolfram syndrome (2 cases), Goldenhar syndrome (3 cases), Cogan syndrome (3 cases), Franceschetti-Kleinsyndrome (1 case), Charge syndrome(1 case), otomandibular syndrome (1 case), Stickler syndrome(1 case), Alström syndrome (1 case), Refsum disease (1 case), Susac syndrome (1 case) and KID Syndrome (1 case). Screening for ocular involvement allowed to shorten the average length of cochlear implantation from 9 months to 3 months. There are numerous ocular and auditory involvements because of the embryological and cellular similarities of these two organs, including the retina and the inner ear. The diagnosis of these involvements is facilitated by the presence of facial dysmorphism; on the other hand, diagnosis is difficult when there are visual and auditory sensorineural involvements. Early diagnosis of ocular and auditory involvements allows for best psychomotor development and optimal social inclusion. Therefore multidisciplinary management is necessary to allow for the best psychomotor, orthophonic and visual rehabilitation.

RESUMO

BACKGROUND: Congenital sensorineural hearing loss (SNHL) is a common disability in children. It can affect normal language development and educational achievement. Today, the time to cochlear implant is delayed for many children, which in turn delays intervention and impacts outcomes. Lack of knowledge and experience with congenital SNHL in the family are critical factors that can delay identification and intervention. OBJECTIVES: Compare treatment seeking behavior in families for a first and second congenitally deaf child. DESIGN: Analytical, cross-sectional using medical record data. SETTING: Ear specialist hospital in Riyadh. SUBJECTS AND METHODS: All patients who presented to the cochlear implant committee from March 2016 to March 2018 and met criteria were included in the study. Data on when the subjects presented to hospital and were approved for cochlear implant were retrieved from the patient files and through phone calls to the family. The age of first suspicion, audiological testing, diagnosis, hearing aid fitting, and the decision for cochlear implant were compared between the first and second child in families with multiple children with congenital SNHL. MAIN OUTCOME MEASURES: The timing difference between the first and second deaf child in seeking treatment. SAMPLE SIZE: 116 (58 pairs). RESULTS: The second child was suspected to have hearing loss 13.6 months earlier than the first child and presented to the cochlear implant committee for final decision 16.7 months earlier than his\her sibling. Differences in the mean ages at suspicion of hearing loss, presentation to the hospital for audiological evaluation, hearing aid fitting, diagnosis, and decision for cochlear implant by cochlear implant committee were statistically significant ( P<.001). CONCLUSION: Experience and knowledge has a major effect on early identification. We need to implement educational programs for the public to increase awareness of how to recognize a deaf child and what steps to take. LIMITATIONS: Single-centered. CONFLICT OF INTEREST: None.

RESUMO

INTRODUCTION: People with vestibular loss present a deficit in the vestibular system, which is primarily responsible for promoting postural control, gaze stabilization, and spatial orientation while the head moves. There is no effective treatment for a bilateral loss of vestibular function. Recently, a vestibular implant was developed for people with bilateral loss of vestibular function to improve this function and, consequently, the quality of life of these patients. OBJECTIVE: To identify in the scientific literature evidence that vestibular implants in people with vestibular deficit improves vestibular function. METHODS: One hundred and forty six articles were found from five databases and 323 articles from the gray literature mentioning the relationship between vestibular implant and vestibular function in humans. The PICOS strategy (Population, Intervention, Comparison and Outcome) was used to define the eligibility criteria. The studies that met the inclusion criteria for this second step were included in a qualitative synthesis, and each type of study was analyzed according to the bias risk assessment of the Joanna Briggs Institute through the critical assessment checklist Joanna Briggs institute for quasi-experimental studies and the Joanna Briggs institute critical assessment checklist for case reports. RESULTS: Of the 21 articles included in reading the full text, 10 studies were selected for the qualitative analysis in the present systematic review. All ten articles analyzed through the critical assessment checklist Joanna Briggs institute showed a low risk of bias. The total number of samples in the evaluated articles was 18 patients with vestibular implants. CONCLUSIONS: Taken together, these findings support the feasibility of vestibular implant for restoration of the vestibulo-ocular reflex in a broad frequency range and illustrate new challenges for the development of this technology.

RESUMO

Objective:To explore the early vowel perception development of pediatric cochlear implant(CI) of 1-3 years old. Method:A total of 123 children who had accepted cochlear implantation under 3 years old were analyzed retrospectively. According to the age of implantation, all participants were divided into two groups as 1 year old group(1-<2) and 2 years old group(2-<3). The vowel perception of mandarin early speech perception(MESP) test scores at 12, 24, 36 momths after implantation as well as the trends in vowel perception between group 1 and normal hearing pediatrics of the same age were analyzed to research the development of vowel perception in pediatric cochlear implants and the effect of implanted age as well as physiological age. Result:The scores improved notably in two groups with the increase of physiological age(P<0.01); The vowel perception of group 1 was significantly better than that of group 2(P<0.01), However, there were great difference between group 1 and normal hearing pediatrics of the same age. Conclusion:With the increase of physiological age, the vowel perception would be improved correspondingly within 3 years of pediatric cochlear implants under the age of 3; However, the earlier the age of implant, the better the vowel perception is.

RESUMO

BACKGROUND: Dichotic speech recognition of side-separated speech stimuli requires their central nervous processing and has been used since the 1950s in a variety of clinical settings. OBJECTIVE: The objective of this study was to investigate the dichotic speech recognition of normal-hearing (NH) subjects, cochlear implant (CI) recipients with single-sided deafness (SSD), and bilateral CI (BilCI) recipients with the dichotic discrimination test according to Feldmann. MATERIALS AND METHODS: The speech recognition of ten adult NH subjects, ten SSD CI recipients, and ten BilCI recipients was determined at 65 dB SPL or 65 dB SPL equivalent for monotic presentation of trisyllabic nouns of the Feldmann test (NH subjects: better ear, poorer ear; SSD CI recipients: NH ear, CI; BilCI recipients: better CI, poorer CI) and for dichotic, i.e., simultaneous side-separated, presentation. RESULTS: The NH subjects showed significantly poorer speech recognition for dichotic presentation than for monotic presentation. Speech recognition of SSD CI recipients was significantly worse with the CI than with the NH ear for both monotic and dichotic presentation. For both presentation conditions, BilCI recipients obtained significantly lower speech recognition with the poorer CI compared to the better CI. With each of the two CI, BilCI recipients had significantly worse speech recognition for dichotic presentation than for monotic presentation. CONCLUSION: All three study groups-NH subjects, SSD CI recipients, and BilCI recipients-were able to recognize dichotically presented speech with both ears. For SSD CI recipients, there was no negative effect of the CI on speech recognition with the NH ear for dichotic presentation.
