OBJECTIVE: Evaluate whether prophylactic antibiotics administered following cochlear implant (CI) surgery impact short-term infection rates. DESIGN: Retrospective, concurrent, case-control. SETTING: Tertiary referral center. PATIENTS: All patients (range, 9 months-91 years) undergoing cochlear implantation between 2013 and 2017 (n = 188). INTERVENTION(S): Starting in 2015, one surgeon stopped prescribing postoperative antibiotics after CI surgery...

PURPOSE: The objective of this study was to achieve uniform reporting of complications and failures in cochlear implantation, to analyze complications and failures and to identify risk factors for complications in a series of over 1300 cochlear implantations. METHODS: In a retrospective chart review and observational study, data from all cochlear implantations from 1987 to 2015 were entered in a custom-made database. Complications were classified using the contracted form of the Clavien-Dindo system and risk factors were identified by statistical analysis...

Objective To identify and clarify current evidence supporting and disputing the effectiveness of perioperative antibiotic use for common otolaryngology procedures. Data Sources PubMed, Embase (OVID), and CINAHL (EBSCO). Review Methods English-language, original research (systematic reviews/meta-analyses, randomized control trials, prospective or retrospective cohort studies, case-control studies, or case series) studies that evaluated the role of perioperative antibiotic use in common otolaryngology surgeries were systematically extracted using standardized search criteria by 2 investigators independently...

An 11-month-old healthy infant girl was noted to have left lower lobe (LLL) opacities on chest X-ray (CXR) after developing desaturations during an elective cochlear implant surgery. Repeat CXR 10 days later revealed hyperexpansion of the left lung and persistent LLL opacity. Chest computerized tomography revealed enlarged mediastinal lymph nodes, left mainstem bronchial obstruction, and nodular opacities. Bronchoscopic biopsy of the endobronchial tissue revealed multiple necrotizing granulomas and grew Mycobacterium avium-intracellulare, Streptococcus viridans, and Actinomyces odontolyticus...

Bacterial infections in healthcare settings are a frequent accompaniment to both routine procedures such as catheterization and surgical site interventions. Their impact is becoming even more marked as the numbers of medical devices that are used to manage chronic health conditions and improve quality of life increases. The resistance of pathogens to multiple antibiotics is also increasing, adding an additional layer of complexity to the problems of employing safe and effective medical procedures. One approach to reducing the rate of infections associated with implanted and indwelling medical devices is the use of polymers that resist the formation of bacterial biofilms...

Cochlear implant (CI) surgery in cholesteatoma is challenging because of the risk of residual or recurrent infection. Although CI could be done with subtotal petrosectomy in single or staged surgery, this surgery needed additional surgical procedures to obliterate the mastoid cavity. This paper describes a new surgical technique for CI surgery in cholesteatoma without external auditory canal closure.

Streptococcus suis (S. suis) is a zoonotic pathogen commonly found in Asian countries. Infection with this bacterium typically clinically presents as meningitis and individuals whom handle swine are at increased risk of developing infections. We present a case of a patient with a S. suis meningitis who worked as a butcher. The 48-year-old man was admitted to our department with headaches, fevers, nausea and bilateral hearing loss. According to his medical history, the patient had sustained a cut on his finger while preparing pork meat...

Introduction  Recent advances in surgical techniques and electrode design have made residual hearing preservation during cochlear implantation (CI) possible, achievable, and desirable. Objectives  The objective of this study was to review the literature regarding methods used for hearing preservation during CI surgery. Data Synthesis  We performed a search in the LILACS, MEDLINE, SciELO, PubMed databases, and Cochrane Library, using the keywords CI, hearing preservation, CI electrode design, and CI soft surgery...

Enlarged vestibular aqueduct syndrome (EVAS) is the most common congenital ear anomaly that causes sensorineural hearing loss in children and may predispose a child to sudden hearing loss from sudden pressure changes or minor head trauma. We report a case of a 4-year-old boy with a history of a ventriculoperitoneal shunt and migraines who presented to the emergency department with parental and child care provider reports of acute hearing loss, without a history of trauma, infection, or hardware malfunction, who was diagnosed with bilateral EVAS...

OBJECTIVE: Identifying the main nursing diagnoses and interventions in children submitted to cochlear implant in the immediate postoperative period. METHOD: A cross-sectional study conducted between February and April 2016, considering nursing history (anamnesis and physical examination) and nursing diagnoses (NANDA - International) with their respective interventions (Nursing Intervention Classification - NIC). Descriptive statistical analysis was used to construct the results...

OBJECTIVE: To analyze clinical signs and better define the underestimated long-term pain after implantation, to discuss etiological hypothesis, and to propose our department treatment algorithm and results. STUDY DESIGN AND SETTING: Retrospective review of children implanted with complaints of atypical pain in the area of device implantation, not in the immediate postoperative period, more than or equal to 4 on the Visual Analog Pain Scale (VAPS: 0-10) in the ENT pediatric department of Trousseau and Necker Enfants Malades Hospitals between 1998 and 2015...

BACKGROUND: Hospital acquired fungal infections are defined as "never events"-medical errors that should never have happened. Systemic Candida albicans infections results in 30-50% mortality rates. Typically, adhesion to abiotic medical devices and implants initiates such infections. Efficient adhesion initiates formation of aggressive biofilms that are difficult to treat. Therefore, inhibitors of adhesion are important for drug development and likely to have a broad spectrum efficacy against many fungal pathogens...

CONCLUSIONS: The straight electrode array with length of 31 mm can be fully inserted using round window insertion in cochlear implantation with Mondini's deformity. It is a safe and effective process, but also a challenging task of the full implantation in children with Mondini's deformity. OBJECTIVE: The aim of this study is to discuss whether the straight electrode array with a length of 31 mm could be fully inserted in cochlear implantation with Mondini's deformity...

BACKGROUND: The inserted cochlear implanted electrode is covered at the site of the round window or cochleostomy to prevent infections and leakage. In a surgically hearing preservational concept, low intracochlear pressure changes are of high importance. The aim of this study was to observe intracochlear pressure changes due to different sealing techniques in a cochlear model. METHODS: Cochlear implant electrode insertions were performed in an artifical cochlear model and the intracochlear pressure changes were recorded in parallel with a micro-pressure sensor positioned in the apical region of the cochlea model to follow the maximum amplitude of intracochlear pressure...

BACKGROUND: Cochlear implant (CI)-related wound infections are known to happen even years after the implant procedure and present a challenging clinical situation. Due to the formation of biofilm on the implant surface such infections are difficult to eradicate. Invariably explantation of the device is required for wound healing. METHOD: A 10-year-old patient presented with recurrent CI-related wound infection 8 years after implantation. The implant was salvaged with wound debridement and treating it with tea tree oil which is known for its biofilm eradicating properties...
