RESUMEN
PURPOSE: Patients with age-related hearing loss complain often about reduced speech perception in adverse listening environment. Studies on animals have suggested that cochlear synaptopathy may be one of the primary mechanisms responsible for this phenomenon. A decreased wave I amplitude in supra-threshold auditory brainstem response (ABR) can diagnose this pathology non-invasively. However, the interpretation of the wave I amplitude in humans remains controversial. Recent studies in mice have established a robust and reliable mathematic algorithm, i.e., curve curvature quantification, for detecting cochlear synaptopathy. This study aimed to determine whether the curve curvature has sufficient test-retest reliability to detect cochlear synaptopathy in aging humans. METHODS: Healthy participants were recruited into this prospective study. All subjects underwent an audiogram examination with standard and extended high frequencies ranging from 0.125 to 16 kHz and an ABR with a stimulus of 80 dB nHL click. The peak amplitude, peak latency, curvature at the peak, and the area under the curve of wave I were calculated and analyzed. RESULTS: A total of 80 individuals with normal hearing, aged 18 to 61 years, participated in this study, with a mean age of 26.4 years. Pearson correlation analysis showed a significant negative correlation between curvature and age, as well as between curvature and extended high frequency (EHF) threshold (10-16 kHz). Additionally, the same correlation was observed between age and area as well as age and EHF threshold. The model comparison demonstrated that the curvature at the peak of wave I is the best metric to correlate with EHF threshold. CONCLUSION: The curvature at the peak of wave I is the most sensitive metric for detecting cochlear synaptopathy in humans and may be applied in routine diagnostics to detect early degenerations of the auditory nerve.
RESUMEN
OBJECTIVE: Accurate positioning of the electrode array during cochlear implant (CI) surgery is crucial for achieving optimal hearing outcomes. Traditionally, postoperative radiological imaging has been used to assess electrode position. Transimpedance matrix (TIM) measurements have also emerged as a promising method for assessing electrode position. This involves utilizing electric field imaging to create an electric distance matrix by analyzing voltage variations among adjacent electrodes. This study aimed to investigate the feasibility of using intraoperative TIM measurements to estimate electrode position and monitor postoperative changes. STUDY DESIGN: Retrospective cohort study. SETTING: University Medical center, tertiary academic referral center. PATIENTS: Patients undergoing CI (CI622) surgery between January 2019 and June 2022. INTERVENTION: CI electrode positions and maximal angular insertion depths (maxAID) were determined using X-ray imaging according to Stenvers' projection. The mean gradient phase (MGP) was extracted from the TIM, and a correlation between the MGP and maxAID was examined. A model was then built to estimate the maxAID using the MGP, and changes in electrode location over time were assessed using this model. MAIN OUTCOME MEASURES: Twenty-four patients were included in this study. A positive correlation between the maxAID and the MGP ( R = 0.7, p = 0.0001) was found. The established model was able to predict the maxAID with an accuracy of 27.7 ± 4.4°. Comparing intraoperative and postoperative TIM measurements, a decrease of 24.1° ± 10.7° in maxAID over time was observed. CONCLUSION: TIM measurements are useful for estimating the insertion depth of the electrode and monitoring changes in the electrode's position over time.

BACKGROUND: Systemic glucocorticoids are commonly used for primary therapy of idiopathic sudden sensorineural hearing loss (ISSNHL). However, the comparative effectiveness and risk profiles of high-dose over lower-dose regimens remain unknown. METHODS: We randomly assigned patients with sudden hearing loss of greater than or equal to 50 dB within 7 days from onset to receive either 5 days of high-dose intravenous prednisolone at 250 mg/d (HD-Pred), 5 days of high-dose oral dexamethasone at 40 mg/d (HD-Dex), or, as a control, 5 days of oral prednisolone (Pred-Control) at 60 mg/d followed by 5 days of tapering doses. The primary outcome was the change in hearing threshold (pure tone average) in the three most affected contiguous frequencies from baseline to day 30. Secondary outcomes included speech understanding, tinnitus, communication competence, quality of life, hypertension, and insulin resistance. RESULTS: A total of 325 patients were randomly assigned. Mean change in 3PTAmost affected hearing threshold from baseline to 30 days was 34.2 dB (95% CI, 28.4 to 40.0) in the HD-Pred group, 41.4 dB (95% CI, 35.6 to 47.2) in the HD-Dex group, and 41.0 dB (95% CI, 35.2 to 46.8) in the Pred-Control group (P=0.09 for analysis of variance). There were more adverse events related to trial medication in the HD-Pred (n=73) and HD-Dex (n=76) groups than in the Pred-Control group (n=46). CONCLUSIONS: Systemic high-dose glucocorticoid therapy was not superior to a lower-dose regimen in patients with ISSNHL, and it was associated with a higher risk of side effects.

Among hearing aid (HA) users, there is a considerable variability in word recognition scores (WRSs). This variability is most pronounced among individuals with moderately severe to severe hearing loss. The variability cannot be adequately explained by factors such as pure-tone audiogram, audiogram type or age. This prospective study was designed to investigate the relationship between tone decay (TD) and WRS in a group of HA users with corresponding pure-tone hearing loss. The study population included 22 patients with hearing loss between 50 and 80 dB HL. Aided WRS, unaided WRS and TD were assessed for both ears. TD was found to be frequency-dependent. TD and WRS were correlated, with up to R = -0.66. The TD test was revealed to be a feasible method for explaining variability in WRS among HA users with hearing loss below 80 dB. This may contribute to improved differential diagnostics. The TD test may thus offer a better understanding of the limitations of HA use in the context of cochlear implant candidacy assessment for HA users.
RESUMEN
Head and neck squamous cell carcinoma (HNSCC) is linked to significant morbidity, adversely affecting survival and functional capacity. Post-treatment challenges such as pain, dysphonia, and dysphagia are common, prompting increased attention in survivorship research. Quality of Life (QoL) questionnaires, especially the MD Anderson Dysphagia Inventory (MDADI), are prevalent outcome measures in clinical studies but often lack parallel objective swallowing function evaluations, leading to potential outcome discrepancies. This study aimed to illuminate the relationship between subjective QoL (EQ-5D-5L and MDADI) measures and objective swallowing function (evaluated via Fiberoptic Endoscopic Evaluation of Swallowing, FEES) in patients with HNSCC. The analysis revealed a notable discordance between objective measures of swallowing function, such as the Penetration-Aspiration Scale (PAS) and residue ratings in the vallecula or piriform sinus, and patients' subjective QoL assessments (p = 0.21). Despite the lack of correlation, swallowing-related QoL, as measured by the MDADI, was more indicative of disease severity than generic QoL assessments. Generic QoL scores did not demonstrate substantial variation between patients. In contrast, MDADI scores significantly declined with advancing tumor stage, multimodal therapy, and reliance on feeding tubes. However, the clinical significance of this finding was tempered by the less than 10-point difference in MDADI scores. The findings of this study underline the limitations of QoL measures as standalone assessments in patients with HNSCC, given their reliance on patient-perceived impairment. While subjective QoL is a crucial aspect of evaluating therapeutic success and patient-centric outcomes, it may fail to capture critical clinical details such as silent aspirations. Consequently, QoL assessments should be augmented by objective evaluations of swallowing function in clinical research and practice to ensure a holistic understanding of patient well-being and treatment impact.

Hearing impairment has been recently identified as a major modifiable risk factor for cognitive decline in later life and has been becoming of increasing scientific interest. Sensory and cognitive decline are connected by complex bottom-up and top-down processes, a sharp distinction between sensation, perception, and cognition is impossible. This review provides a comprehensive overview on the effects of healthy and pathological aging on auditory as well as cognitive functioning on speech perception and comprehension, as well as specific auditory deficits in the 2 most common neurodegenerative diseases in old age: Alzheimer disease and Parkinson syndrome. Hypotheses linking hearing loss to cognitive decline are discussed, and current knowledge on the effect of hearing rehabilitation on cognitive functioning is presented. This article provides an overview of the complex relationship between hearing and cognition in old age.

Objective: The suitable electrode array choice is broadly discussed in cochlear implantation surgery. Whether to use a shorter electrode length under the aim of structure preservation versus choosing a longer array to achieve a greater cochlear coverage is a matter of debate. The aim of this review is to identify the impact of the insertion depth of a cochlear implant (CI) electrode array on CI users' speech perception outcomes. Databases Reviewed: PubMed was searched for English-language articles that were published in a peer-reviewed journal from 1997 to 2022. Methods: A systematic electronic search of the literature was carried out using PubMed to find relevant literature on the impact of insertion depth on speech perception. The review was conducted according to the preferred reporting items for systematic reviews and meta-analyses guidelines of reporting. Studies in both, children and adults with pre- or postlingual hearing loss, implanted with a CI were included in this study. Articles written in languages other than English, literature reviews, meta-analyses, animal studies, histopathological studies, or studies pertaining exclusively to imaging modalities without reporting correlations between insertion depth and speech outcomes were excluded. The risk of bias was determined using the "Risk of Bias in Nonrandomized Studies of Interventions" tool. Articles were extracted by 2 authors independently using predefined search terms. The titles and abstracts were screened manually to identify studies that potentially meet the inclusion criteria. The extracted information included: the study population, type of hearing loss, outcomes reported, devices used, speech perception outcomes, insertion depth (linear insertion depth and/or the angular insertion depth), and correlation between insertion depth and the speech perception outcomes. Results: A total of 215 relevant studies were assessed for eligibility. Twenty-three studies met the inclusion criteria and were analyzed further. Seven studies found no significant correlation between insertion depth and speech perception outcomes. Fifteen found either a significant positive correlation or a positive effect between insertion depth and speech perception. Only 1 study found a significant negative correlation between insertion depth and speech perception outcomes. Conclusion: Although most studies reported a positive effect of insertion depth on speech perception outcomes, one-third of the identified studies reported no correlation. Thus, the insertion depth must be considered as a contributing factor to speech perception rather than as a major decisive criterion. Registration: This review has been registered in PROSPERO, the international prospective register of systematic reviews (CRD42021257547), available at https://www.crd.york.ac.uk/PROSPERO/.
RESUMEN
INTRODUCTION: Surgical obliteration is the treatment of choice for symptomatic mastoid cavities. Various methods and materials are available. Allogeneic material is easily available but can lead to wound infections due to rejection, granulation and inflammatory reactions. Consequently, autologous material is often preferred due to its good biocompatibility. The aim of this study was to compare the long-term outcomes of patients after mastoid cavity obliteration with allogeneic and autologous material with regard to the occurrence of recurrent cholesteatoma, the number of revision surgeries and the impact of surgery on the health-related quality of life. METHODS: Patients who underwent mastoid cavity obliteration with an allogeneic material (hydroxyapatite matrix [HMM]) were retrospectively included in the study. In a prospective part, patients who underwent mastoid cavity obliteration with autologous reconstruction material (AutoM) were included. In addition to a detailed chart review, all patients underwent pure tone audiometry and completed the Zurich Chronic Middle Ear Inventory (ZCMEI-21) at the postoperative examination to assess health-related disease-specific quality of life. RESULTS: A total of 22 patients with a mean age of 56.9 (SD 18.7 years) receiving HMM (mean follow-up interval: 88.3 months [SD 21.9 months]) and 25 patients with a mean age of 52.4 years (SD 13.7 years) receiving AutoM (mean follow-up interval: 13.5 months [SD 9.5 months]) were included in the study. The revision-free rate for audiological indication after one year was 100% for HMM and 85% for AutoM. The recurrence-free rate at one year was 95% for HMM and 100% for AutoM. 55% of the patients with alloplastic material and 8% of the patients with autologous material required revision surgery due to ear discharge or recurrent cholesteatoma. The groups did not differ in terms of postoperative hearing outcome or postoperative quality of life. DISCUSSION: Obliteration of mastoid cavities is a surgical challenge. There was no relevant difference between the materials used in terms of recurrence rate, hearing and health-related quality of life within the 13.5-month observation period of both groups. The lack of subjective symptoms together with the high rate of recurrent cholesteatoma and revision indications emphasises the need for regular clinical follow-up including ear microscopy in chronic middle ear disease and strongly suggests regular follow-up examinations.

Vestibular schwannomas (VS) are benign tumors that originate from the nerve sheath of one of the two vestibular nerves. VS can have a severe impact on everyday life of the patient and may lead to symptoms such as vertigo, hearing loss (e.g., as sudden deafness), deafness, and tinnitus. Treatment concepts include observational waiting with regular imaging control ("wait and scan"), radiotherapy, or surgical resection. Depending on the size of the tumor and status of functional hearing, the surgical approach may be retrosigmoidal, transtemporal, retrolabyrinthine, or translabyrinthine. The translabyrinthine approach always results in complete deafness due to opening of the bony labyrinth. If the nerve structure of the cochlear nerve is preserved, hearing rehabilitation with a cochlear implant (CI) may be successful. In this article the surgical technique for microsurgical resection of VS using a translabyrinthine approach with simultaneous cochlear implantation under intraoperative monitoring of the cochlear nerve by electrical stimulation is presented.

BACKGROUND: With increasing access to online teaching materials, traditional teaching methods at universities need to be questioned in the context of digital transformation. The aim of this study was to evaluate whether electronic learning may serve as or replace conventional internship in otorhinolaryngology. MATERIALS AND METHODS: A completely digital electronic learning concept was created and made available at the online learning platform ILIAS. Students were introduced to the program. Four learning units (neck [I], pharynx/larynx [II], nose [III], ear [IV]) were set up, with a topic-related multiple-choice test at the end of each unit. The students took part in the evaluation before and after completion of the course. RESULTS: A total of 105 students participated in the evaluation before and 85 students after the electronic learning program. After completing the courses, the majority of students (52.94%) stated to be more satisfied with the content and the presentation of the learning sequences as well as with their own self-control concerning learning pace and time management compared to the situation before completing the program (34.29%; pâ¯<â¯0.0001). The majority of students (54.12%) stated that they would appreciate the electronic learning program in addition to practical internship. CONCLUSION: The electronic learning program is a promising approach to supplement traditional learning and internships. An expansion of digital teaching proposals should be supported based on this study.

PURPOSE: Different types of chronic middle ear disease (CMED) present with differing severity of single symptoms, such as discharge, vertigo or hearing loss, which impair health-related quality of life (HRQoL). Here, we aimed to (i) investigate characteristics of HRQoL and (ii) evaluate the association between HRQoL and hearing among different types of CMED. METHODS: In this prospective longitudinal cohort study, we included adult patients undergoing surgical treatment for CMED. Primary outcomes included HRQoL assessed by the Zurich Chronic Middle Ear Inventory (ZCMEI-21) and hearing assessed by pure-tone audiometry. RESULTS: In the included 108 patients (51% females), CMED were chronic otitis media (COM) with (n = 46) or without (n = 22) cholesteatoma, persistent mastoid cavity (with [n = 15] or without [n = 10] recurrent cholesteatoma), revision ossiculoplasty for hearing restoration (n = 14), and postinflammatory meatal fibrosis (n = 1). Preoperatively, the mean ZCMEI-21 score showed statistically significant differences among different types of CMED (p = 0.007) with persistent mastoid cavity without cholesteatoma exhibiting the highest score (34.1, SD 7.7) indicating poor HRQoL. At a mean follow-up period of 183 days, no statistically significant differences in the ZCMEI-21 scores among different types of CMED were observed (p = 0.67). CONCLUSION: This study objectifies differences in HRQoL among different types of CMED. In patients with indication for functional surgery only, e.g., persistent mastoid cavity without cholesteatoma, the worst HRQoL was observed. Yet, in these types of CMED, HRQoL guides decision for treatment. Moreover, differences in HRQoL among different types of CMED were not closely associated with hearing, but largely depended on other symptoms, such as discharge or vertigo.

OBJECTIVE: To assess the change in health-related quality of life (HRQoL) in patients undergoing mastoid cavity obliteration. METHODS: Patients who had undergone canal wall-down mastoidectomy for chronic otitis media with creation of a persistent mastoid cavity and underwent revision tympanomastoid surgery including mastoid cavity obliteration using autologous material were included. Audiological measurements including air conduction (AC) and bone conduction (BC) pure-tone averages (PTA) and the air-bone gap (ABG) were assessed. Health-related Quality of Life (HRQoL) was assessed by the Zurich Chronic Middle Ear Inventory (ZCMEI-21) pre- and postoperatively. RESULTS: A total of 25 patients (16 females and 9 males; mean age 51.6 years, 14 right and 11 left ears) were included. Patients were reexamined after a mean follow-up period of 9.2 months (SD = 6.5) after obliteration of the mastoid cavity. Compared to the preoperative visit, patients showed a significantly reduced AC PTA at the postoperative visit (mean difference: - 4.1; SD = 10.4, p = 0.045). The mean ZCMEI-21 score changed from 31.7 (SD = 14.5) preoperatively to 17.4 (SD = 15.1) postoperatively (mean difference: - 14.3; SD = 19.1; p = 0.0002). The mean ZCMEI-21 score changes were neither correlated to the AC PTA shift (p = 0.60) nor to the ABG shift (p = 0.66). CONCLUSIONS: This is the first study reporting a highly significant and clinically important improvement in HRQoL after mastoid cavity obliteration in a prospective setting. The improvement in HRQoL was not correlated to the hearing improvement. As a clinical implication, we provide evidence for a substantial subjective benefit of the surgical obliteration of a symptomatic mastoid cavity and, therefore, encourage this surgical procedure.

OBJECTIVE: Validation of the preoperative sound simulation test for vibroplasty-hearing so-called "Direct Drive Simulation" (DDS) in case of mixed hearing loss. STUDY DESIGN: Retrospective data analysis. SETTING: Tertiary referral center with a large hearing implant program. MAIN OUTCOME MEASURE: Comparison of sound impression during preoperative Direct Drive Simulation, and postoperative testing with the activated active middle ear implant (AMEI) under free-field condition and in daily routine. PATIENTS: Fifty-four data sets from 18 patients with mixed hearing loss with a mean age of 60.78â±â3.18 were included. RESULTS: Comparing the sound impression during DDS preoperatively versus free-field testing with the implanted AMEI, no significant differences were found. DDS offers a slightly better sound quality than the AMEI in daily routine, fitting well to the ideal listening situation in DDS versus some background noise in daily routine. CONCLUSION: The DDS offers the possibility of a realistic preoperative sound simulation of the "vibroplasty-hearing" in cases of mixed hearing loss. This probably facilitates patient's decision towards a vibroplasty. The audiologist as well as the surgeon get additional information regarding the indication especially when audiologic inclusion criteria are critical. Thus, the DDS is a useful extension of preoperative diagnostics before vibroplasty.

OBJECTIVES: To compare the results of ossiculoplasty with two different partial ossicular replacement prostheses (PORP) to ossiculoplasty with a total ossicular replacement prosthesis (TORP) in patients with an intact stapes suprastructure. METHODS: All patients required primary or revision surgery for chronic middle ear disease and ossicular reconstruction with either a PORP or a TORP, as well as a with an intact stapes suprastructure. In total, 141 patients receiving classic tympanoplasty with PORP (N = 92), ossiculoplasty with PORP with ball joint (N = 22), or TORP (N = 27) between January 2011 and March 2017 were included in this study. The inclusion criterion was an intact stapes suprastructure. The underlying indication for surgery was either middle ear disease, such as cholesteatoma, or revision surgery for audiological improvement. The main outcome measures were four-frequency pure tone average (0.5, 1, 2, 3 kHz) at early and late follow-up after ossiculoplasty, the effects of clinical factors including the underlying middle ear disease, and primary or revision surgery. RESULTS: All patients showed a significantly reduced air-bone gap (ABG 0.5, 1, 2, 3 kHz) at late follow-up (mean: 18 dB) compared to preoperative measurements (mean: 25.5 dB). A significantly better outcome in ABG closure was shown among patients with a preoperatively intact tympanic membrane, with an intact stapes suprastructure or without preexisting cholesteatoma. Outcome was not significantly influenced by the prosthesis-type, the creation of an open mastoid cavity, the status of the mucosa, or the indication for surgery. CONCLUSION: TORP with an intact stapes suprastructure is a safe procedure and provides audiological outcomes similar to PORP. LEVEL OF EVIDENCE: 2C Laryngoscope, 130:768-775, 2020.

OBJECTIVES: To compare quality-of-life (QoL) measurements with audiological results after stapes surgery with two different prostheses. METHODS: This is a retrospective longitudinal study. All patients required stapes surgery for otosclerosis and ossicular chain reconstruction with either a titanium band prothesis (TBP) or receiving a nitinol head prosthesis (NHP). Intervention was between January 2011 and March 2017 patients received stapes-surgery with either TBP (n = 95) or NHP (n = 50). Audiological measurements at three different time points (preoperatively, early follow up < 3 months, late follow-up > 3 months) were compared and two different QoL-inventories, the Glasgow-Benefit-Inventory (GBI) and the Stapes-Plasty-Outcome-Test-25 (SPOT-25) were investigated postoperatively. The main outcome measures were Pure tone average (PTA) at 0.5, 1, 2, 3 kHz at early and late follow up after stapes surgery were compared and correlated with the subjective benefit on the QoL inventories. The perforation method and the type of surgery were analyzed as potentially influencing factors. RESULTS: All patients showed a significantly reduced air bone gap (ABG 0.5, 1, 2, 3) at the two follow-up visits (visit 2: mean: 13.6 dB, SD 7.7; visit 3: mean: 12.7 dB SD 8.1) compared to preoperative measurements (mean: 28.9 dB, SD 9.9) and subjectively benefitted from stapes surgery (mean GBI score: 21.55; SD 20.60, mean SPOT-25 score: 28.03; SD 18.53). The outcome of the two questionnaires correlated with each other. Neither the hearing-outcome nor the subjective benefit was significantly influenced by the prosthesis, the perforation method or the type of anesthesia. CONCLUSIONS: Both prostheses were safe and led to comparable hearing results as well as to subjective benefits in the Health-related-Quality-of-Life (HrQoL). A combination of the two questionnaires is recommendable for postoperative quality control.

OBJECTIVES: Foreign body incorporation in children is often a serious situation. Attention deficit hyperactivity disorder (ADHD) could be a risk factor for self-insertion of foreign bodies. Large cohort analyses are missing. METHODS: This was a retrospective analysis of patients' records from a health insurance company representing 2.19% of the German population and 1.75% of German children and adolescents. According to the International Classification of Diseases, children in the age range between 1 and 18 years have been screened for foreign bodies in ear, nasal sinus and nostrils as well as for hyperkinetic disorders (F90), disorders of psychological development (F80-F89), and congenital malformations, deformations and chromosomal abnormalities (Q00-Q99). RESULTS: In total, 12887 children (6609 male; 6278 female) have been treated in 16929 cases. The majority (nâ¯=â¯10041 (77.9%)) presented with foreign body incorporation on a single occasion. On average, 1.31 cases of foreign body treatment were recorded per child; 14.1% of children with foreign body treatment (FBT) also had a record of hyperkinetic disorder, 52.7% had a disorder of psychological development, and 50.8% a congenital malformation. Mean occurrence of FBT was 174.8 days before the diagnosis of a hyperkinetic disorder but 517.2 days after the diagnosis of a psychological development disorder and 683.1 days after the diagnosis of a congenital malformation, deformation or chromosomal abnormality. CONCLUSION: Patients with disorders of psychological development as well as children with congenital malformations are high-risk patients for nasal and aural foreign bodies. The prevalence of a hyperkinetic disorder in patients with FBT is much higher than in the normal population. ADHD is a risk factor for foreign bodies.

INTRODUCTION: Since 1996 the active middle-ear implant Vibrant Soundbridge (VSB) is used to treat mild-to-severe sensorineural hearing losses. The former standard surgical approach for incus vibroplasty included a mastoidectomy and a posterior tympanotomy, crimping the Floating-Mass Transducer (FMT) to the long incus process. The introduction of the short process (SP) coupler allows the attachment of the FMT to the incus body making the procedure of a posterior tympanotomy unnecessary. The aim of this study was to evaluate the duration of surgery (surgical case length) and to compare the audiological results of SP coupling with the former standard surgical approach to the long incus process. MATERIALS AND METHODS: Patients undergoing an incus vibroplasty between October 2009 and February 2016 were included in this cohort study. The patients received an incus vibroplasty with crimping the FMT to the long incus process (former standard application) (nâ=â25) and with the SP coupler (nâ=â17) respectively. The surgical case length as well as the functional audiological outcome was assessed 12 months postoperatively using pure-tone audiometry and speech audiometry. RESULTS: The surgical case length was significantly shorter in the SP coupler group compared to the standard application incus vibroplasty (85â±â29âmin vs. 114â±â50âmin). Additionally, patients receiving the SP coupler had an increased speech perception if compared to the standard application (Freiburger monosyllables at 65âdB SPL: 76.1â±â16.1% vs. 66.2â±â23.5%). CONCLUSION: The SP coupler leads to a shortened time of surgery and by the less invasive surgery to reduced risks for facial nerve and chorda tympani. Speech perception is significantly improved by SP coupling compared to classic long incus coupling.

OBJECTIVE: To evaluate the effects of neurostimulation with the laryngeal pacemaker (LP) system in patients with bilateral vocal fold paralysis (BVFP) in terms of voice quality and respiratory function. STUDY DESIGN: Feasibility study, first-in-human, single-arm, open-label, prospective, multicenter study with group-sequential design and 6-month follow-up period, as described in details in our previous publication. METHODS: Nine symptomatic BVFP subjects were unilaterally implanted with the LP system at three study sites in Germany and Austria. Subjective and objective voice function, spirometric parameters other than peak expiratory/inspiratory flow (PEF/PIF), and PEF-meter self-assessment were evaluated pre- and 6 months postimplantation. RESULTS: In general, the LP system did not considerably change the voice quality of the implanted patients. Only the sound pressure level range improved significantly 6 months postimplantation (P = 0.018). The LP system implantation did not affect the glottal closure configuration, the duration of the closed phase, and the mucosal wave of the implanted side. The evaluated spirometric parameters were not significantly affected by laryngeal pacing, whereas PEF meter self-assessment showed a stable and significant (P = 0.028) improvement of the PEF within a week upon activation of the LP system. CONCLUSION: Neurostimulation with the LP system results in an immediate and stable PEF improvement, without negative effects on the voice quality. The PEF meter self-assessment confirmed the spirometry results of the PEF. The stimulated abduction did not affect the glottal closure during phonation. These results should be confirmed in larger and more homogenous patient cohorts. LEVEL OF EVIDENCE: 2b Laryngoscope, 127:1838-1844, 2017.
