Abstract
BACKGROUND Acute mastoiditis (AM) is the most common complication of acute otitis media and primarily affects children under the age of two; current data on its prevalence in paediatric patients with cochlear implant (CI) are still scant. Proper management of AM in CI children is crucial in order to avoid the implications (financial and emotional) of an explant. Aim of this paper is to describe the cases of AM occurred among young patients with CI in follow up at our department, also in order to evaluate its prevalence, potential predisposing factors, clinical course and therapeutic strategies. PATIENTS AND METHODS Retrospective study. Medical records of all paediatric patients with CI, who had at least one year of follow-up, were searched aiming to identify those who developed AM, from January 1st 2002 to January 31st 2022. The following data were collected and analysed: demographic features, implant type and side, interval between CI surgery and AM, treatment, laboratory tests, clinical course, vaccination history, associated diseases. RESULTS AM was developed by six (1.3%) of the 439 children with CI (541 implanted ears). In total, 9 episodes (2.05 %) were recorded, as three patients reported two consecutive infections. Average time interval between CI surgery, to the first or only AM diagnosis, was 13.8 months (range 3-30 months). Furthermore, 3/6 of patients had a history of recurrent acute otitis media; 2/6 an autism spectrum disorder, associated to a combined immune deficiency in one case. All patients were hospitalized and promptly treated by intravenous antibiotic therapy; 4/6 also underwent a mastoidectomy. CI was not explanted in any cases of this series. CONCLUSIONS Over a 20-year period, AM rate in CI children was 1.3%, which is consistent with the current literature rates of 1-4.7%. All cases were successfully treated, preserving the integrity of the device. In our experience, the early parenteral antibiotic therapy and, when necessary, surgical treatment were adequate to eradicate the infection.

Abstract
INTRODUCTION Intratemporal or intracranial complications of acute mastoiditis are often of significant severity, can be life-threatening, and require prompt and usually aggressive treatment. This study focused on analyzing the outcomes and complications of different surgical techniques used in intracranial and intratemporal complications of acute mastoiditis, the most common complication of acute otitis media. METHODS A retrospective study of pediatric patients with mastoiditis with intratemporal and intracranial complications was designed at the Niño Jesús University Children's Hospital in Madrid, Spain, from 2005 to 2021. RESULTS Of 417 patients with mastoiditis, 112 patients developed intratemporal and intracranial complications, with subperiosteal abscess being the most frequent complication. The most frequently isolated pathogens were Streptococcus pneumoniae, Streptococcus pyogenes, and Fusobacterium necrophorum. The most used surgical technique was myringotomy with placement of transtympanic drainage, in 86.6% of all cases. In patients with intracranial complications, neurosurgical procedures were necessary for 19.2%, with craniotomy with mastoidectomy being the most frequent. Most of the cases evolved favorably, and only 5.4% of the patients required surgical reintervention, being more frequent in intratemporal complications. In terms of complications, we found cases of neutropenia in 3.6%, neurological sequelae in 5.4%, and permanent hearing loss in 2.7%. CONCLUSIONS There was a favorable evolution with a low incidence of reoperation and sequelae within our series. The surgical technique of choice correlated with the severity of the complication. If the mean size of the abscess exceeds 20 mm, incision and drainage, along with myringotomy and tube placement, should be considered as the initial treatment. Closed mastoidectomy should be reserved for deteriorating of clinical evolution or acute mastoiditis with intracranial complications. Intracranial and multiple concomitant complications were associated with a more extended hospital stay, ICU occupancy, neurosurgical intervention, and risk of neurological sequelae and neutropenia. Conversely, intratemporal complications may result in permanent hearing loss.

Abstract
OBJECTIVE To describe the natural history, detail the treatment patterns, and identify the risk factors for cochlear implant (CI) infections in a large US cohort. STUDY DESIGN Retrospective study based on insurance claims. SETTING Optum Data Mart database: 6101 patients who received CIs from 2003 to 2019. METHODS Infections, treatments patterns, and timelines were described. A multivariable logistic regression model was used to assess the association between postoperative oral antibiotics and CI infection. RESULTS The cohort includes 4736 (77.6%) adults and 1365 (22.4%) children. Between adult and pediatric patients, rates of CI infection (5.1% vs 4.5%, P = .18) and explantation (1.2% vs 0.8%, P = .11) were not significantly different. Infections typically occurred within 5 months of surgery. Children were diagnosed with CI infection earlier than adults (median difference, -1.5 months; P = .001). Postoperative oral antibiotic supply was not associated with lower risk of CI infection in either children or adults. However, among adults, otitis media was associated with higher odds of CI infection (odds ratio, 1.41; P < .001), while higher income was associated with lower odds of CI infection (odds ratio, 0.71; P = .03). CONCLUSIONS Postoperative oral antibiotics were not associated with lower risk of infection or interventions. Otitis media episodes and lower income were associated with increased risk of infection among adults as well as intervention overall. Infection typically presented within the first 6 months after surgery, with children presenting earlier than adults. Overall, our findings serve as a resource for providers to consider in their care of patients with CIs.

Abstract
There are a growing number of medically complex children with implanted devices. Emergency physicians with a basic knowledge of these devices can troubleshoot and fix many of the issues that may arise. Recognition of malfunction of these devices can reduce morbidity and mortality among this special population. In this article, we review common issues that may arise in children with gastrostomy tubes, central nervous system shunts, cochlear implants, and vagal nerve stimulators.

Abstract
OBJECTIVE To determine factors associated with infection, management, and resultant outcomes following pediatric cochlear implantation. STUDY DESIGN Retrospective cohort study with nested case series. SETTING Tertiary academic medical center. PATIENTS Children who underwent either unilateral or bilateral cochlear implantation between June 2011 and September 2016 and were under the age of 18 at the time of surgery. INTERVENTION(S) Subjects were compared based on age, cochlea malformation, revision surgery, operative time, device manufacturer, and antibiotic use. Infections were compared based on location, time, bacteria, management, and resolution. MAIN OUTCOME MEASURE(S) Rate of infection, rate of device explantation. RESULTS There were 16 infections among 246 surgeries, an infection rate of 6.5%. There was a significant age difference between infected and noninfected patients overall (n = 246, 1.4 versus 4.3 years, p = 0.005), but not within the cohort of patients five or younger (n = 172, 1.4 versus 1.8 years, p = 0.363). The most common infectious complication was skin infection, followed by device infection. No cases of meningitis were seen. The most common organism was S Aureus. The implant was salvaged in 9 of 16 patients (56.3%), with higher rates in patients treated with IV versus oral antibiotics (70 versus 40%). CONCLUSIONS Postoperative infection is positively associated with younger age overall, but not in patients below the age of 5. With modern devices and surgical practices, risk of meningitis-though a concern-may be lower than cited in the literature. Prompt and aggressive therapy with IV antibiotics and operative intervention can allow for high rates of device salvage.

Abstract
OBJECTIVE Infectious complications occurring in cochlear implant (CI) recipients is of potentially major impact. A better understanding of severe infections in this cohort is necessary. DESIGN Single-center, retrospective cohort study. Level of Evidence 2B. SETTING Single-center, retrospective cohort study at a tertiary referral hospital. PARTICIPANTS AND INTERVENTIONS We included all patients who received a CI at our institution between 1983 and end of 2018 (4,622 implantations). MAIN OUTCOMES Prevalence, incidence, risk factors, and functional outcomes in severe implant infections. RESULTS There was an overall prevalence of 0.65% of severe CI infections. The cumulative incidence decreased after the year 2000, with lower infection rates with newer implant models. Patients with local risk factors were more susceptible to implant infection. In most patients, delayed re-implantation was successful. Speech-perception after re-implantation was comparable to pre-revision performance. CONCLUSIONS Modified implant design and improved surgical technique has led to a decrease in the prevalence and incidence of infected implants. In severe implant infections, active surgical and antimicrobial management is required, to achieve good long-term results.

Abstract
Introduction Acute mastoiditis remains the most common complication of acute otitis media. It may rarely appear also in cochlear implant patients. However, the treatment recommendations for this disease are not precisely defined or employed, and in the current literature the differences regarding both the diagnosis and management are relatively substantial. Objective The aim of this study was to determine a standard and safe procedure to be applied in case of pediatric acute mastoiditis. Methods A retrospective chart review of 73 patients with 83 episodes of acute mastoiditis hospitalized at our tertiary-care center between 2001 and 2016 was conducted. Bacteriology, methods of treatment, hospital course, complications, and otologic history were analyzed. Based on our experience and literature data, a protocol was established in order to standardize management of pediatric acute mastoiditis. Results All the patients treated for acute mastoiditis were submitted to an intravenous antibiotic regimen. In the analyzed group pharmacological treatment only was applied in 11% of children, in 12% myringotomy/tympanostomy was added, and in the vast majority of patients (77%) mastoidectomy was performed. In our study recurrent mastoiditis was noted in 8% of the patients. We also experienced acute mastoiditis in a cochlear implant child, and in this case, a minimal surgical procedure, in order to protect the device, was recommended. Conclusions The main points of the management protocol are: initiate a broad-spectrum intravenous antibiotic treatment; mastoidectomy should be performed if the infection fails to be controlled after 48 h of administering intravenous antibiotic therapy. We believe that early mastoidectomy prevents serious complications, and our initial observation is that by performing broad mastoidectomy with posterior attic and facial recess exposure, recurrence of acute mastoiditis can be prevented.

Abstract
OBJECTIVES Recurrent acute mastoiditis is repeatedly reported in the literature, but data to understand the pathogenesis, update treatment recommendations and inform future trials are sparse due to the infrequency of the disease. METHODS A retrospective chart review from 2001 to 2016 was conducted including 73 children treated for acute mastoiditis. A follow-up survey was attempted for each patient. Bacteriology, method of treatment, hospital course, complications, and otologic history were analyzed. A chi-squared test, Fisher's exact test and Mann-Whitney U test compared recurrent acute mastoiditis to single acute mastoiditis cases. Additionally, a comprehensive PubMed search and review of world literature addressing recurrent pediatric acute mastoiditis was performed for comparative purposes. RESULTS Among 73 children with acute mastoiditis, six (8%) experienced recurrent acute mastoiditis. Streptococcus pneumoniae was the only bacteria isolated in this group. History of recurrent acute otitis media (>4 per year) prior to the first episode of acute mastoiditis was identified in 24% with single episode of acute mastoiditis and 83% with recurrent mastoiditis (p < 0.05). Fewer intracranial/intratemporal complications were identified among recurrent mastoiditis patients (p < 0.05). In a group of patients treated with more extensive surgical communication during mastoidectomy for primary acute mastoiditis (wide mastoidectomy with broad attic exposure and posterior tympanotomy) no recurrence was observed. CONCLUSION We identify multiple risk factors associated with recurrence and provide early data supporting anatomic predisposition to the development of recurrent acute mastoiditis. More aggressive opening between the mastoid cavity and middle ear may prevent recurrent acute mastoiditis episodes.

Abstract
When acute mastoiditis occurs in cochlear implant recipients, it can progress to subsequent retroauricular abscess due to the absence of the external mastoid cortex resulting from mastoidectomy performed for cochlear implantation. The management goal is to control infection while preserving the implanted device. A 2-year-old boy with cochlear implants developed acute mastoiditis and a subsequent retroauricular abscess. The patient underwent a surgical intervention based on the diagnosis made utilizing gray-scale and power Doppler sonography. This case illustrates the diagnostic usefulness of sonography in this rare situation. © 2017 Wiley Periodicals, Inc. J Clin Ultrasound 45:515-519, 2017.

Abstract
INTRODUCTION In Internet forums and other social media many reports regarding chronic headaches after cochlear implantation can be found. Although quite rare, there are also some reports in the literature. However, little is known regarding the true prevalence of headaches in persons who have undergone cochlear implant surgery. OBJECTIVES The primary aim of this study was to investigate the 1-year prevalence of headache in patients having received a cochlear implantation ("cochlear implant group") in comparison with patients having undergone middle ear surgery ("surgery group") and persons with no history of head and neck surgery ("non-ear-nose-throat [ENT] group"). METHODS Cross-sectional, monocentric study using a validated headache questionnaire. RESULTS Three hundred persons were asked to participate. Two hundred thirty four valid questionnaires were returned. The participants' median age was 62 years, of whom 45% were women. The prevalence of headache was 31% (95%-confidence interval [CI]: [21; 42]) in the cochlear implant group and 46% (95%-CI: [35; 57]) in the surgery group with no significant difference between these two subgroups (p = 0.071). In the non-ENT group the prevalence of headache was significantly higher than in the other two subgroups (64%, 95%-CI: [52; 74]). DISCUSSION The prevalence of headache is not higher in cochlear implant patients in comparison to middle ear surgery patients, other, non-ENT patients and the general German or European population. CONCLUSION Cochlear implantation does not seem to be associated with an increased risk for developing headache.

Abstract
OBJECTIVES Cochlear implantation is performed at a young age, when children are prone to acute otitis media. Acute mastoiditis is the most common complication of otitis media, but data on its management in the presence of a cochlear implant are sparse. The objective of this study was to assess the characteristics, treatment, and outcome of acute mastoiditis in children with a cochlear implant. METHODS The medical files of all children who underwent cochlear implantation at a pediatric tertiary medical center in 2000-2014 were retrospectively reviewed. Those diagnosed with acute mastoiditis after implantation were identified, and data were collected on demographics, history, presentation, method of treatment, complications, association with untreated otitis media with effusion, and long-term middle-ear sequelae. RESULTS Of the 370 children (490 ears) who underwent cochlear implantation, 13 (3.5%) were treated for acute mastoiditis (median age at acute mastoiditis, 32 months). Nine had a pre-implantation history of chronic secretory or acute recurrent otitis media, and 5 had been previously treated with ventilation tubes. In all 9 children who had unilateral cochlear implant, the acute mastoiditis episode occurred in the implanted ear. The time from implantation to mastoiditis was 5-61 months. The same treatment protocol as for normal-hearing children was followed, with special attention to the risk of central nervous system complications. Primary treatment consisted of myringotomy with intravenous administration of wide-spectrum antibiotics. Surgical drainage was performed in 8 out of 13 patients, with (n=7) or without (n=1) ventilation-tube insertion, to treat subperiosteal abscess or because of lack of symptomatic improvement. There were no cases of intracranial complications or implant involvement or need for a wider surgical approach. No middle-ear pathology was documented during the average 3.8-year follow-up. CONCLUSIONS The relatively high rate of acute mastoiditis and subperiosteal abscess in children with a cochlear implant, predominantly involving the implanted ear, supports the suggestion that recent mastoidectomy may be a risk factor for these complications. Despite the frequent need for drainage, more extensive surgery is usually unnecessary, and recovery is complete and rapid. As infections can occur even years after cochlear implantation, children with otitis media should be closely followed, with possible re-introduction of ventilation tubes.

Abstract
UNLABELLED OBJECTIVES AND IMPORTANCE: Cochlear implantation is an established, reliable, and safe procedure with a low complication rate. Electrode array extrusion through the posterior aspect of external ear canal is a potential major complication of cochlear implant surgery that may result in revision surgery or explantation. Although there have been previous case reports of such extrusions through the tympanic membrane, this is the first well-documented report of an extrusion through the posterior canal wall which was previously intact. CLINICAL PRESENTATION In this case report, we present a case of electrode array extruding through an initially intact posterior canal wall presenting as a delayed post-operative complication in a 13-year old Asian boy. INTERVENTION With reference to existing relevant literature, the case is discussed focusing on its management, possible contributing factors, and prevention strategies. CONCLUSION Excessive thinning of the bony wall should be avoided as it can potentially break down. Abutment on the posterior canal wall by a coiled electrode array in the mastoid cavity exerting undue pressure on the bony wall can further contribute to additional stress. The implant surgeon must be cognizant of mastoid growth patterns in children. Life-long regular follow-up in implanted patients is crucial.
