Factors correlated with hearing aids adherence in older adults: a prospective controlled study.

OBJECTIVE: To investigate which factors influence the adherence to hearing aid (HA) use in elderly patients with moderate-to-severe hearing loss. METHODS: This observational, prospective, single-centre study enrolled patients with moderate-to-severe hearing loss. They were evaluated before and 1 year after having either one or two HAs fitted. RESULTS: A total of 86 patients were enrolled in the study and of these 69.8% (60 of 86; USER group) continued to use their HA at 1 year after fitting; six patients had not continued their use (NON-USERS). The USER group was younger than the NON-USER group, but the difference was not significant. The USER group had a significantly better unaided auditory threshold at baseline than the NON-USER group. HA use resulted in improvements in speech audiometry and auditory threshold. There was also a maintenance of cognitive function in the USER group. CONCLUSION: Use of HA for 1 year resulted in improved auditory performance and an absence of a deterioration of cognitive function.Trial registration: This research was retrospectively registered under no.

Narrative skills and language comprehension in preschool children with cochlear implants: A comparison with children with Developmental Language Disorder or typical development.

INTRODUCTION: The narrative skills of children with cochlear implants (CIs) are fragile, but the factors at play and whether these difficulties could be similar to those detected in language impairment are not clear. The present study aims to assess, at the microstructural level, narrative skills, comparing children with CIs with children with Developmental Language Disorder (DLD) or Typical Development (TD). Furthermore, the relationship between verbal (lexical and morphosyntactic) comprehension and narrative skills across groups is investigated. METHODS: The narratives of 19 children with CIs (Mage = 62.42 months, SD = 6.83), 13 children with DLD (Mage = 65.38 months, SD = 4.27), and 18 preschool children with TD (Mage = 63.67 months, SD = 4.31) were assessed in a standardized task. Articles, prepositions, pronouns, gender and number agreement, accuracy in the use of verbs, and number of arguments in each sentence were analysed. Lexical and morphosyntactic comprehension were also assessed. Performance was compared across groups using ANOVAs or Kruskal-Wallis tests. The role of lexical and morphosyntactic comprehension in predicting each morphological and syntactic element in the narrative task was examined using linear regressions. RESULTS: Data analysis showed that both children with CIs and DLD had fragilities in narration, both in the morphological and syntactic components. Although some differences between children with CIs and those with DLD emerged in descriptive analyses, these were not statistically significant. Regressions showed that morphosyntactic comprehension predicted the number of pronouns produced only in the TD group. CONCLUSIONS: The scarce differences between CI and DLD groups and the absence of an effect of morphosyntactic comprehension on pronoun production may be due to their low production of these elements in the narrative task and/or to a difficulty in managing pronouns in an expressive task regardless of their ability to comprehend them. Potential implications of these results are discussed.

Hearing Loss in Baraitser-Winter Syndrome: Case Reports and Review of the Literature.

Background: Baraitser-Winter Syndrome (BRWS) is a rare autosomal dominant condition associated with hearing loss (HL). In the literature, two types of this condition are reported, Baraitser-Winter type 1 (BRWS1) and type 2 (BRWS2) produced by specific pathogenetic variants of two different genes, ACTB for BRWS1 and ACTG1 for BRWS2. In addition to syndromic BRWS2, some pathogenic variants in ACTG1 are associated also to another pathologic entity, the "Autosomal dominant non-syndromic hearing loss 20/26". In these syndromes, typical craniofacial features, sensory impairment (vision and hearing) and intellectual disabilities are frequently present. Heart anomalies, renal and gastrointestinal involvement and seizure are also common. Wide inter- and intra-familial variety in the phenotypic spectrum is reported. Some phenotypic aspects of these syndromes are not yet fully described, such as the degree and progression of HL, and better knowledge of them could be useful for correct follow-up and treatment. Methods and Results: In this study, we report two cases of children with HL and diagnosis of BRWS and a review of the current literature on HL in these syndromes.

Do Different Types of Microphones Affect Listening Effort in Cochlear Implant Recipients? A Pupillometry Study.

BACKGROUND: It is known that subjects with a cochlear implant (CI) need to exert more listening effort to achieve adequate speech recognition compared to normal hearing subjects. One tool for assessing listening effort is pupillometry. The aim of this study is to evaluate the effectiveness of adaptive directional microphones in reducing listening effort for CI recipients. METHODS: We evaluated listening in noise and listening effort degree (by pupillometry) in eight bimodal subjects with three types of CI microphones and in three sound configurations. RESULTS: We found a correlation only between sound configurations and listening in noise score (p-value 0.0095). The evaluation of the microphone types shows worse scores in listening in noise with Opti Omni (+3.15 dB SNR) microphone than with Split Dir (+1.89 dB SNR) and Speech Omni (+1.43 dB SNR). No correlation was found between microphones and sound configurations and within the pupillometric data. CONCLUSIONS: Different types of microphones have different effects on the listening of CI patients. The difference in the orientation of the sound source is a factor that has an impact on the listening effort results. However, the pupillometry measurements do not significantly correlate with the different microphone types.

Implantable hearing devices in clinical practice. Systematic review and consensus statements.

Objective: Implantable hearing devices represent a modern and innovative solution for hearing restoration. Over the years, these high-tech devices have increasingly evolved but their use in clinical practice is not universally agreed in the scientific literature. Congresses, meetings, conferences, and consensus statements to achieve international agreement have been made. This work follows this line and aims to answer unsolved questions regarding examinations, selection criteria and surgery for implantable hearing devices. Materials and methods: A Consensus Working Group was established by the Italian Society of Otorhinolaryngology. A method group performed a systematic review for each single question to identify the current best evidence on the topic and to guide a multidisciplinary panel in developing the statements. Results: Twenty-nine consensus statements were approved by the Italian Society of Otorhinolaryngology. These were associated with 4 key area subtopics regarding pre-operative tests, otological, audiological and surgical indications. Conclusions: This consensus can be considered a further step forward to establish realistic guidelines on the debated topic of implantable hearing devices.

Emotional abilities in preadolescents and adolescents with long-term cochlear implant use.

OBJECTIVES: Emotional abilities (EAs) are particularly important during preadolescence/adolescence, two challenging periods characterized by significant biological, physical, and cognitive changes. The present study attempted to a holistic EA approach in preadolescents/adolescents with cochlear implants (CI) and typical hearing (TH), considering various aspects such as perception, cognitive facilitation, comprehension, and management of emotions. A secondary aim was to identify significant demographic and audiological factors of EA development. METHODS: CI/TH groups were matched for chronological age, nonverbal IQ, gender, economic income, and maternal level of education. Each group consisted of 43 participants (age range 10-18 years). EAs were evaluated by using the multi-trait/method IE-ACCME test. Auditory-linguistic assessments included participants' lexical skills and Matrix performance as well. RESULTS: EA performance for perception and cognitive facilitation did not show any statistically significant CI/TH group differences (p > 0.05). Significant CI/TH differences emerged for emotion comprehension and management: CI group performed significantly worse in understanding emotional blends (t = 2.56, p = 0.014) but better in personal emotion management (t = -2.01, p = 0.048). For the CI group, gender showed statistically significant effects on cognitive facilitation in sensations, with males performing better than females (U = 129, p = 0.018). TH preadolescents showed significantly lower scores in understanding emotional changes in comparison to TH adolescents (U = 125.5, p = 0.01). Emotional blends understanding showed a weak negative correlation with Matrix performance (r = - 0.38, p = 0.013) and a moderate positive correlation with lexical skills (r = 0.40, p = 0.008). Relationships management showed various significant correlations: weak negative correlations with age at CI (r = - 0.38, p = 0.011) and Matrix performance (r = - 0.36, p = 0.016) as well as weak positive correlations with nonverbal-IQ (r = 0.38, p = 0.013) and positive moderate correlations with lexical skills (r = 0.49, p < 0.001). CONCLUSION: Cochlear implantation seems to show significant positive effects on emotional development in children, allowing them to achieve age appropriate EAs as they grow up and become preadolescents/adolescents. EA assessment in CI users may not only support monitorization of EA trajectory, but also early identification of any EA disorders, so that subjects with low EA profiles could be timely and properly intervened.

Cavitating Lesions around the Cochlea Can Affect Audiometric Threshold and Clinical Practice.

There are several pathologies that can change the anatomy of the otic capsule and that can distort the bone density of the bony structures of the inner ear, but otosclerosis is one of the most frequent. Similar behavior has been shown in patients affected by osteogenesis imperfecta (OI), a genetic disorder due to a mutation in the genes coding for type I (pro) collagen. In particular, we note that otosclerosis and OI can lead to bone resorption creating pericochlear cavitations in contact with the internal auditory canal (IAC). In this regard, we have collected five cases presenting this characteristic; their audiological data and clinical history were analyzed. This feature can be defined as a potential cause of a third-window effect, because it causes an energy loss during the transmission of sound waves from the oval window (OW) away from the basilar membrane.

Current trends on subtotal petrosectomy with cochlear implantation in recalcitrant chronic middle ear disorders.

Objective: To establish the safety and effectiveness of subtotal petrosectomy with cochlear implantation in patients affected by chronic middle ear disorders to refractory to previous surgical treatments. Methods: A multicentre, retrospective study was conducted on patients affected by recalcitrant chronic middle ear disorders who underwent cochlear implantation in combination with subtotal petrosectomy. Patients' details were collected from databases of 11 Italian tertiary referral centres. Additionally, a review of the most updated literature was carried out. Results: 55 patients were included with a mean follow-up time of 44 months. Cholesteatoma was the most common middle ear recurrent pathology and 50.9% of patients had an open cavity. 80% of patients underwent a single stage surgery. One case of explantation for device failure was reported among the 7 patients with post-operative complications. Conclusions: Subtotal petrosectomy with cochlear implantation is a benchmark for management of patients with recalcitrant chronic middle ear disorders. A single stage procedure is the most recommended strategy. Optimal follow-up is still debated. Further studies are required to investigate the role of this surgery in paediatric patients.

The influence of auditory selective attention on linguistic outcomes in deaf and hard of hearing children with cochlear implants.

PURPOSE: Auditory selective attention (ASA) is crucial to focus on significant auditory stimuli without being distracted by irrelevant auditory signals and plays an important role in language development. The present study aimed to investigate the unique contribution of ASA to the linguistic levels achieved by a group of cochlear implanted (CI) children. METHODS: Thirty-four CI children with a median age of 10.05 years were tested using both the "Batteria per la Valutazione dell'Attenzione Uditiva e della Memoria di Lavoro Fonologica nell'età evolutiva-VAUM-ELF" to assess their ASA skills, and two Italian standardized tests to measure lexical and morphosyntactic skills. A regression analysis, including demographic and audiological variables, was conducted to assess the unique contribution of ASA to language skills. RESULTS: The percentages of CI children with adequate ASA performances ranged from 50 to 29.4%. Bilateral CI children performed better than their monolateral peers. ASA skills contributed significantly to linguistic skills, accounting alone for the 25% of the observed variance. CONCLUSIONS: The present findings are clinically relevant as they highlight the importance to assess ASA skills as early as possible, reflecting their important role in language development. Using simple clinical tools, ASA skills could be studied at early developmental stages. This may provide additional information to outcomes from traditional auditory tests and may allow us to implement specific training programs that could positively contribute to the development of neural mechanisms of ASA and, consequently, induce improvements in language skills.

Postoperative Benefit of Bone Anchored Hearing Systems: Behavioral Performance and Self-Reported Outcomes

Abstract Introduction Bone anchored hearing solutions are a well-known option for patients with a conductive, mixed conductive-sensorineural hearing loss and those with single-sided deafness. Objective The aim of the present study was to evaluate the Ponto bone-anchored hearing system in terms of behavioral performance and self-reported outcomes, by comparing unaided and aided performance (softband and abutment), as well as aided performance with the sound processor on softband (preoperatively) versus abutment (postoperatively). Methods Fourteen adult bone-anchored candidates, with either a bilateral (n = 12) or unilateral (n = 2) conductive or mixed hearing loss, participated in the present study. Sound-field hearing thresholds were evaluated unaided and aided (softband and abutment). A speech-in-noise test was also performed unaided and aided for two spatial configurations (S0N90; implanted side; S0N90; nonimplanted side). The Glasgow Health Status Inventory and the Speech, Spatial and Quality of sound questionnaires were administered pre- and postsurgery to compare quality of life and perceived unaided and aided performance. Skin reaction (Holgers scores) was evaluated at 15 days, 6 weeks, and 10 weeks after surgery. Results Significant improvements postoperatively relative to unaided were obtained for sound-field thresholds at all tested frequencies. Additionally, sound-field thresholds were significantly improved with the sound processor on abutment relative to the softband at frequencies > 1 kHz. Improved performance postoperatively relative to unaided was also obtained in the speech-in-noise test and in self-reported outcomes. Conclusions Improvements in behavioral performance and self-reported outcomes were obtained with the sound processor mounted on abutment.

An Adaptation and Validation Study of the Speech, Spatial, and Qualities of Hearing Scale (SSQ) in Italian Normal-Hearing Children.

This study aimed to translate and adapt the English version of the Speech, Spatial, and Qualities of Hearing Scale (SSQ) for children and for parents into the Italian language; validate SSQ for hearing children and their parents; and evaluate the discriminant validity of the instrument. A group of 102 normal-hearing Italian children, aged between 9 and 16 years, and their parents were included in this study. A group of 31 parents of normal-hearing Italian children aged between 6 and 8 years was also included. A group of 57 hearing-impaired Italian children aged between 9 and 16 years, and their parents were also included, as well as a group of 30 parents of hearing-impaired Italian children aged between 6 and 8 years. Cronbach's alpha in the SSQ for parents was 0.92; it was 0.95 in the SSQ for children. Guttmann's split-half coefficient in SSQ for children for both λ4 and λ6 was 0.98; in SSQ for parents in λ4 was 0.96 and λ6 was 0.95. These data provide evidence for the discriminant validity of the SSQ scale (p-value < 0.001). Italian SSQ scales for children and for parents are now available.

Survey on Use of Local and Systemic Corticosteroids in the Management of Chronic Rhinosinusitis with Nasal Polyps: Identification of Unmet Clinical Needs.

Background: Local and systemic corticosteroids have long been the workhorse in management of chronic rhinosinusitis with nasal polyps (CRSwNP), although there is no universally accepted modality of prescription. We carried out a survey in Italy to capture current trends in the use of topical and systemic corticosteroids in patients with CRSwNP. Methods: A survey was set up on Survey Monkey®. Each author distributed the link to the survey in an ad hoc manner and a total of 437 participants filled out the survey. Results: Mometasone furoate (79.3%) was the most frequently prescribed, administered daily by 61.9% of participants; the remaining preferred to discontinue treatment for brief periods to reduce side effects or to modulate the therapy in mild cases. The majority believe that a short cycle of systemic steroids should be prescribed for re-exacerbation of symptoms and that the number of cycles in the previous year should be evaluated to define control of the disease even if international guidelines do not provide clear indications on this topic. A certain degree of divergence emerged from responses regarding how long and the maximal dose of systemic steroids which place patients at high risk for adverse events. Finally, systemic corticosteroids seem to offer only temporary benefit on recovery of smell without guaranteeing long-term control even if the patient is adherent to topical corticosteroids. Conclusions: Our results highlight the need for clear guidelines on oral steroids, which could help supporting the use of a precision medicine approach, including indications for new biological agents.

Cost-Utility Analysis of Dupilumab for the Treatment of Chronic Rhinosinusitis with Nasal Polyps (CRSwNP) in Italy.

The objective of this analysis was to estimate the incremental cost-utility ratio (ICUR) of dupilumab as an add-on treatment to best supportive care (BSC), versus BSC alone, in Italy for severe uncontrolled chronic rhinosinusitis with nasal polyps (CRSwNP). A simulation of outcomes and costs was undertaken using a 1-year decision tree, followed by a lifetime horizon Markov model. Clinical data were derived from a pooled analysis of two studies (SINUS-24 NCT02912468 and SINUS-52 NCT02898454). The Italian National Healthcare Service (NHS) perspective was considered. Model robustness was tested through sensitivity analyses. In the base-case analysis, treatment with dupilumab + BSC resulted in an increase in quality of life-adjusted survival (+1.02 quality-adjusted life years (QALY-gained)), compared to the BSC alone. The resulted ICUR was €21,817 per QALY-gained and it is below the acceptability threshold commonly used in Italy. Both one-way deterministic and probabilistic sensitivity analyses confirmed the robustness of base-case results. The cost-utility analysis showed that dupilumab, as an add-on treatment to BSC, is a cost-effective therapeutic alternative to BSC in the treatment of patients with severe uncontrolled chronic rhinosinusitis with nasal polyps, confirming that it is economically sustainable.

Auditory evaluation of infants born to COVID19 positive mothers.

COVID-19 infection can cause a wide spectrum of symptoms. The audio-vestibular system can also be involved, but there is still debate about this so findings need to be considered carefully. Furthermore, mother to fetus intrauterine transmission of COVID-19 infection in pregnant women is controversial. Few studies are available about the audio-vestibular symptomatology of newborns with intrauterine COVID19 exposure. OBJECTIVES: This study investigates the possible correlation between the COVID19 gestational infection and hearing impairment onset in newborns. The involvement of hearing in COVID19 is verified so the timing and methodology of audiological evaluation of children can be planned. METHODS: Children were subject to newborn hearing screening and audiological evaluation. Newborn hearing screening is carried out prior to hospital discharge using the Automatic Transient Evoked Otoacoustic Emissions test. Audiological evaluation is performed within the child age of 4 months by using maternal, pregnancy, and perinatal case history, COVID19 case history, otoscopy, acoustic immittance test, Distortion Product Otoacoustic Emissions test, and the Auditory Brainstem Response test. RESULTS: 63 children were included in the study. 82.5% of these children were subjects of the newborn hearing screening program. The remaining 11 newborns were not subjected to hearing screening due to isolation measures and their audiological evaluation was carried out directly. Only one of 52 screened neonates showed a bilateral REFER test result but hearing threshold was normal at audiological evaluation. Audiological evaluation showed normal bilateral ABR thresholds in 59/63 children. Four children (6.3% of the total) had ABR threshold alterations but two showed normal threshold at ABR retest performed within 1 month of the first. The other two infants showed monolateral ABR alterations but one of these had a concomitant middle ear effusion. In conclusion, only one child (1.6% of the sample) had an altered ABR. This child had shown one positive SARS-CoV-2 swab in the absence of risk factors for hearing loss. CONCLUSION: This study finds no evidence that maternal COVID19 infection is a risk factor in the development of congenital hearing loss in newborns.

Listening comprehension in profoundly deaf children with cochlear implants: the role of auditory perception and foundational linguistic and cognitive skills.

PURPOSE: The aim of the study was to investigate the listening comprehension (LC) skills in deaf and hard of hearing children (DHH) using cochlear implants (CI). Besides, personal and audiological variables that could influence the levels of competence reached were analyzed. METHODS: Thirty-four children using CI were enrolled. LC skills were assessed through the standardized Italian test "Comprensione Orale-Test e Trattamento" (CO-TT). A univariate analysis was conducted to compare LC with gender, listening mode (unilateral or bilateral), maternal level of education and family income. A bivariate analysis was performed to search possible connections between children's performances and their individual characteristics, audiological conditions, and language levels. Finally, a multivariate analysis was performed using a stepwise hierarchical linear regression model which included all variables whose p value resulted ≤ 0.05. RESULTS: Twenty-one children using CI (61.8%) showed adequate performances in terms of chronological age, while 13 (38.2%) showed difficulties in LC. Maternal level of education, age at diagnosis and non-verbal cognitive level accounted for 43% of the observed variance. Auditory attention skills explained an additional 15% of variance. Morphosyntactic comprehension added a further 12% of variance. CONCLUSION: CI can really help many DHH children to reach adequate LC skills, but in some cases difficulties remain. Factors influencing LC need to be early investigated and considered when planning an appropriate rehabilitative intervention.

Cochlear Implant in Patients with Intralabyrinthine Schwannoma without Tumor Removal.

(1) Background: Schwannomas of the vestibulocochlear nerve are benign, slow-growing tumors, arising from the Schwann cells. When they originate from neural elements within the vestibule or cochlea, they are defined as intralabyrinthine schwannomas (ILSs). Cochlear implant (CI) has been reported as a feasible solution for hearing restoration in these patients. (2) Methods: Two patients with single-sided deafness (SSD) due to sudden sensorineural hearing loss and ipsilateral tinnitus were the cases. MRI detected an ILS. CI was positioned using a standard round window approach without tumor removal. (3) Results: The hearing threshold was 35 dB in one case and 30 dB in the other 6 mo after activation. Speech audiometry with bisillables in quiet was 21% and 27% at 65 dB, and the tinnitus was completely resolved or reduced. In the localization test, a 25.9° error azimuth was obtained with CI on, compared to 43.2° without CI. The data log reported a daily use of 11 h and 14 h. In order to not decrease the CI's performance, we decided not to perform tumor exeresis, but only CI surgery to restore functional binaural hearing. (4) Conclusions: These are the sixth and seventh cases in the literature of CI in patients with ILS without any tumor treatment and the first with SSD. Cochlear implant without tumor removal can be a feasible option for restoring binaural hearing without worsening the CI's performance.

Bulging of the Oval Window in Common Cavity Deformity: A Possible Predictor of Meningitis.

OBJECTIVE: To investigate the prevalence-rate of oval window bulging in the common cavity and its association with bacterial meningitis. PATIENTS: CT and clinical files of 29 children with preliminary diagnosis of common cavity deformity were collected from 13 Italian centers. INTERVENTION: A retrospective case review study was conducted with a centralized evaluation of the temporal bone CT imaging was performed at Azienda Ospedale - Università Padova, Padova, Italy. MAIN OUTCOME MEASURE: Diagnosis of common cavity was reviewed; in addition, a fluid protrusion into the middle-ear cavity through the oval window at CT imaging was considered as oval window bulging. Its association with the history of bacterial meningitis was investigated. RESULTS: Common cavity deformity was confirmed in 14/29 children (mean-age 11.4 ±â€Š3.8; age-range 5-20; nine females) referred with this diagnosis. In 7/14 patients, the common cavity deformity was bilateral (i.e., 21 common cavities). Oval window bulging was found in 3/19 common cavities (concomitant middle-ear effusive otitis hampered the evaluation in two cases), while the internal acoustic meatus fundus was defective in 10/21 cases. History of bacterial meningitis was found in three children (21%) and two of them had oval window bulging at CT. In the case unrelated to oval window bulging, meningitis occurred late at the age of 12 during acute otitis contralateral to common cavity deformity (ipsilaterally to incomplete partition type 1). CONCLUSION: Patients harboring common cavity deformity have a high risk of meningitis in their first years of life. Oval window bulging seems to be associated with a higher risk of meningitis. This information might be important for appropriate surgical planning.

Comparison between linear incision and punch techniques for bone anchored hearing aid surgery.

OBJECTIVES: To evaluate mean surgical time, incidence of soft tissue reactions, implant survival and intraoperative complications in both minimally invasive ponto surgery (MIPS) and the linear incision with tissue preservation technique (LT). METHODS: A retrospective review was carried out on 48 bone anchored hearing system (BAHS) patients between 2014 and 2019: 13 patients had undergone LT and formed one group, while 35 patients had undergone MIPS and formed the second group. Mean surgical time, intraoperative complications, implant loss and skin reaction were assessed at each post-operative examination. The Mann-Whitney U test was used for statistical analysis. RESULTS: The difference in the mean surgical time of 15 mins for MIPS and 36 mins for LT was statistically significant. No intraoperative complications were reported and implant survival was 100% in both groups. The incidence of adverse skin reactions was 7.7% for the LT group and 0% for the MIPS group at first follow-up examination. CONCLUSIONS: Surgical mean time is shorter for MIPS, making this procedure more suitable for local anaesthesia and more cost effective. Moreover, both LT and MIPS demonstrate good surgical outcomes in terms of skin reactions according to Holgers score and equally excellent implant survival.
