RESUMEN
PURPOSE: This study aimed to determine whether preoperative depressiveness, stress, and personality influence quality of life (QOL) after cochlear implant (CI) surgery. METHODS: In this prospective study, 79 patients undergoing CI surgery were evaluated preoperatively and 12 months postoperatively. Disease-specific QOL was assessed with the Nijmegen Cochlear Implant Questionnaire (NCIQ) and general QOL with the WHOQOL-BREF. Depressiveness and stress were assessed with the Patient Health Questionnaire (PHQ-D). The Charlson Comorbidity Index (CCI) was used to classify comorbidities. The Big Five Personality Test (B5T) was used to assess the basic personality dimensions. Speech comprehension was evaluated in quiet with the Freiburg monosyllable test and in noise with the Oldenburg sentence test. RESULTS: After CI surgery, the total NCIQ score improved significantly (Δ 17.1 ± 14.7, p < 0.001). General QOL (WHOQOL-BREF, Δ 0.4 ± 9.9, p = 0.357), stress (Δ 0.25 ± 3.21, p = 0.486), and depressiveness (Δ 0.52 ± 3.21, p = 0.121) were unaffected by CI surgery. Patients without elevated depressiveness (p < 0.01) or stress (p < 0.001) had significantly better total NCIQ scores. The results of the multiple regression analyses show that, after adjusting for the CCI, personality, age, and mental health stress (ß = - 0.495, p < 0.001) was significantly associated with postoperative NCIQ outcome scores. Depressiveness and neuroticism had the strongest influence on the generic QOL (ß = - 0.286 and ß = - 0.277, p < 0.05). CONCLUSION: Stress symptoms and personality traits are significant predictive factors for disease-specific QOL, as well as hearing status. This should be considered in the preoperative consultation and in optimizing the rehabilitation process.

BACKGROUND: With the Chronic Ear Survey (CES), a validated measurement instrument for the assessment of disease-specific health-related quality of life (HRQoL) has been available internationally since 2000. The aim of this study was to provide a validated German version of this international instrument and to compare it with the German Chronic Otitis Media Outcome Test 15 (COMOT-15). METHODOLOGY: The CES was translated into German via a forward-backward translation process. For validation, 79 patients with COM undergoing middle ear surgery were prospectively included. HRQoL was determined preoperatively and 6 months postoperatively using the CES and the COMOT-15. Pure tone audiometry was also performed at both measurement time points. In the control examination, an additional retrospective assessment of the preoperative situation was additionally performed using the CES and the COMOT-15 to assess the response shift. The determined psychometric characteristics were internal consistency, test-retest reliability, discrimination validity, agreement validity, responsiveness, and response shift for both measurement instruments. Convergent validity of both measurement instruments was assessed using linear regression. RESULTS: On the basis of the CES, patients with COM could be reliably distinguished from patients with healthy ears. The CES showed satisfactory reliability with high internal consistency (Cronbach α 0.65-0.85) and high retest reliability (râ¯> 0.8). The global assessment of HRQoL impairment correlated very well with the scores of the CES (râ¯= 0.51). In addition, it showed a high sensitivity to change (standardized response mean -0.86). Compared to the COMOT-15, it showed a lower response shift (effect size -0.17 vs. 0.44). Both measurement instruments correlated only slightly with air conduction hearing threshold (râ¯= 0.29 and râ¯= 0.24, respectively). The concordant validity of both measurement instruments was high (râ¯= 0.68). CONCLUSION: The German version of the CES shows satisfactory psychometric characteristics, so that its use can be recommended. The CES focuses on the influence of ear symptoms on HRQoL, whereas the COMOT-15 also includes functional and psychological aspects. Due to only minor response shift effects, the CES is particularly suitable for studies with multiple repeat measurements.

BACKGROUND: Patients with a cochlear implant (CI) should be evaluated for a new speech processor every 6 years. The aim of this analysis was to assess the subjective and audiological benefit of upgrades. METHODS: Speech understanding and subjective benefit were analyzed in 99 patients with the old and the new speech processor after 4 weeks of wearing. Speech understanding was assessed using the Freiburg monosyllabic test in quiet (FBE) at 65â¯dB and 80â¯dB, and the Oldenburg Sentence Test (OLSA) at 65â¯dB noise with adaptive speech sound level. The Abbreviated Profile of Hearing Aid Benefit (APHAB) was used to assess subjective hearing impairment, and the Audio Processor Satisfaction Questionnaire (APSQ) was used to assess subjective satisfaction. RESULTS: The speech processor upgrade resulted in a significant improvement of speech understanding in quiet at 65â¯dB (mean difference 8.9⯱ 25.9 percentage points, pâ¯< 0.001) and 80â¯dB (mean difference 8.1⯱ 29.7 percentage points, pâ¯< 0.001) and in noise (mean difference 3.2⯱ 10.7â¯dB signal-to-noise ratio [S/N], pâ¯= 0.006). Using the APHAB, a significant improvement (mean difference 0.07⯱ 0.16, pâ¯< 0.001) in hearing impairment was demonstrated in all listening situations. The APSQ showed significantly higher patient satisfaction with the new speech processor (mean difference 0.42⯱ 1.26, pâ¯= 0.006). A comparative assessment of the benefit based on subjective and speech audiometric results identified a proportion of patients (35-42%) who subjectively benefited from the upgrade but had no measurable benefit based on speech audiometry. CONCLUSION: There was a significant improvement in audiologically measurable and subjectively reflected speech understanding and patient satisfaction after the upgrade. In patients with only a small improvement in audiologically measurable speech understanding, the subjective benefit should also be assessed with validated measurement instruments in order to justify an upgrade to the payers in the health sector.

OBJECTIVE: The present study deals with the implementation of a questionnaire with 360° evaluation to assess the performance of students in the practical year (PJ). A special focus is put on the "soft skills" (self-competence, methodological competence, social competence), whose evaluation in medical studies has not yet taken place comprehensively. MATERIAL & METHODS: The study was conducted prospectively with 21 PJ students of the Medical Faculty of the TU Dresden. The assessment was performed by means of a self-designed questionnaire, which was divided into 4 sub-competencies (self-competence, methodological competence, social competence, clinical skills and abilities), which could be assessed by means of a 6-point Likert scale. Four professions were involved in the assessment: Medical Service, Nursing Service, Functional Service, and Administration. RESULTS: On average, the strongest deficits in terms of self-confidence, willingness to perform, and ability to deal with conflict were revealed by students in the PJ. Students showed a very good performance in performing a medical history and basic skills of clinical examination. CONCLUSION: The implementation of 360° feedback is possible and useful for students in the internship year across disciplines and professions. Such personal and interprofessional feedback has not been widely available. The questionnaire represents the first comprehensive measurement tool of soft skills for medical students and provides a good basis for comprehensive feedback.

OBJECTIVES: The active middle ear implant, Vibrant Soundbridge (VSB), can be implanted with a variety of couplers. Hearing outcome after implantation has been investigated in both temporal bone (TB) experiments and patient studies, but the relationship between experimental and clinical data is still weak in the literature. Therefore, experimental data from TB experiments should be compared with patient data in a retrospective study, in which the floating mass transducer is used with couplers of the third generation. Actuator coupling structures included the long (LP coupler) and short (SP coupler) incus process, the stapes head (Clip coupler), and the round window membrane (RW soft coupler). METHODS: In the TB experiments, the sound transmission after vibroplasty on the above-mentioned actuator coupling structures was determined in 32 specimens by means of laser Doppler vibrometry on the stapes footplate. Data of 69 patients were analyzed. The main target audiometric parameters were the postoperative aided word recognition score (WRS) in the free field at 65 dB SPL (WRS 65 dB in %), the preoperative and postoperative pure-tone average (PTA4, including the frequencies 0.5, 1, 2, and 4 kHz) of the bone conduction hearing threshold (PTA4BC), the aided postoperative air conduction hearing threshold in the free field (PTA4FF) and the direct threshold (Vibrogram) at least 6 months postoperatively. The coupling efficiency of the actuator (Vibrogram-PTA4BC) as well as the effective hearing gain (PTA4FF-PTA4BC) was compared between the couplers. RESULTS: The analysis in the main speech range (0.5-4 kHz) indicated that in the TB experiments, the LP coupler tends to have the best coupling quality at low frequencies (500-1000 Hz). This was up to 15 dB above the worst actuator (RW soft coupler). However, the results missed the significance level ( p > 0.05). In the high frequencies (2000-4000 Hz), the Clip coupler showed the best coupling quality. This was 15 dB above the worst actuator (SP coupler). However, the results missed the significance level ( p > 0.05), too. The postoperative WRS at 65 dB SPL and the postoperative PTA4FF were independent of the actuator coupling structure. The PTA4BC was stable at 6 months postoperatively. For the PTA4 of the coupling efficiency, there were no significant differences between the actuator coupling structures (LP 8.9 dB ± 12.9; SP 9.5 ± 6.5 dB; Clip 5.2 ± 10.5 dB; RW 12.7 ± 11.0 dB). However, the tendential inferiority of the RW soft coupler with regard to transmission in the low-frequency range and the tendential superiority of the Clip coupler in the high-frequency range that have already been displayed experimentally could be confirmed in the clinical results. However, the clinical results missed the significance level, too ( p > 0.05). CONCLUSIONS: In vivo, there are no significant differences in the postoperative outcome stratified according to coupling the target structure. The differences known from the experimental setting were repressed by individual biasing factors. However, to ensure sufficient postoperative speech intelligibility, the frequency-specific transmission behavior of the couplers should be taken into account when setting the indication for VSB implantation.

PURPOSE: During COVID-19, a fully digital course was established for teaching and assessing the psychomotor skills of clinical head and neck examination. Influence of different digital teaching formats was investigated. METHODS: The students (n = 286) received disposable instruments, a manual, and instructional videos for the examination. 221 students additionally received 45 min of interactive teleteaching. After 5 days of practice, all students were required to submit a video of their examination and report their spent practice time. The assessment was carried out using a checklist which was already established in presence teaching. RESULTS: The average score achieved by digital teaching was 86%. Previously published data show that presence teaching achieved 94%. With a teleteaching unit the total score was significantly better than without (87% vs 83%). Teleteaching leads to a significant positive correlation between practice time and total score. Without teleteaching there is a negative correlation. After the same practice time, presence teaching leads to better total scores than digital teaching. CONCLUSION: Digital teaching and assessing of a complex psychomotor skill is possible. Interactive teaching methods increase learning success. Nevertheless, presence teaching seems to be better at teaching these skills. The results can provide a basis for developing hybrid teaching models.

OBJECTIVE: The goal of this study was to determine open field stapedius reflex thresholds (oSRTs) in CI patients with fittings based on subjective loudness ratings. A further objective was to compare these oSRTs and those of eSRT-based fittings that are similar to the oSRTs of normal hearing. DESIGN: Impedance measurements of the ear drum were taken while subjects were wearing their audio processors. The stapedius reflex was elicited by electrical stimulation transmitted through the activated CI system in response to an acoustic stimulus presented in the free sound field. STUDY SAMPLE: Subjects were 50 experienced CI users (n = 57 ears) with CI fittings based on subjective loudness scaling. RESULTS: A reference range for the oSRTs was defined that was identified in CI patients with eSRT-based fittings. Sound levels for stapedius reflex detection were inside the reference target range in 70% of the cases, below the reference range (i.e. down to 40 dB HL) in 20% of the cases, and above the reference range in 10% of the cases. CONCLUSION: Stapedius reflex detection in a free sound field may help detect fittings with too high or too low stimulation levels that might reduce audiological performance.
RESUMEN
BACKGROUND: The active transcutaneous bone conduction implant (tBCI; BONEBRIDGE™ BCI 601; MED-EL, Innsbruck, Austria) is fixed to the skull with two self-tapping screws in predrilled screw channels. The aim of this prospective study was to evaluate the safety and effectiveness of fixation with self-drilling screws instead of the self-tapping screws, in order to simplify the surgical procedure. MATERIALS AND METHODS: Nine patients (mean age 37⯱ 16 years, range 14-57 years) were examined pre- and 12 months postoperatively for word recognition scores (WRS) at 65â¯dB SPL, sound-field (SF) thresholds, bone conduction thresholds (BC), health-related quality of life (Assessment of Quality of Life, AQOL-8D questionnaire), and adverse events (AE). RESULTS: Due to avoidance of one surgical step, the surgical technique was simplified. Mean WRS in SF was 11.1⯱ 22.2% (range 0-55%) pre- and 77.2⯱ 19.9% (range 30-95%) postoperatively; mean SF threshold (pure tone audiometry, PTA4) improved from 61.2⯱ 14.3â¯dB HL (range 37.0-75.3â¯dB HL) to 31.9⯱ 7.2â¯dB HL (range 22.8-45.0â¯dB HL); mean BC thresholds were constant at 16.7⯱ 6.8â¯dB HL (range 6.3-27.5â¯dB HL) pre- and 14.2⯱ 6.2â¯dB HL (range 5.8-23.8â¯dB HL) postoperatively. AQOL-8D mean utility score increased from 0.65⯱ 0.18 preoperatively to 0.82⯱ 0.17 postoperatively. No device-related adverse events occurred. CONCLUSION: Implant fixation by means of self-drilling screws was safe and effective in all nine patients. There was significant audiological benefit 12 months after implantation.

CONCLUSION: The German version of the CES shows satisfactory psychometric characteristics, so that its use can be recommended. The CES focuses on the influence of ear symptoms on HRQoL, whereas the COMOT-15 also includes functional and psychological aspects. Due to only minor response shift effects, the CES is particularly suitable for studies with multiple repeat measurements.

BACKGROUND: Chronic otitis media (COM) can lead to significant impairment of health-related quality of life (HRQoL) due to symptoms such as otorrhea, pain, hearing loss, tinnitus, or dizziness. A systematic assessment of HRQoL in COM is becoming increasingly important as it complements (semi-)objective outcome parameters in clinical practice and research. HRQoL is measured by means of patient-reported outcome measures (PROMs). There are two disease-specific validated PROMs available for COM in German-the Chronic Otitis Media Outcome Test (COMOT-15) and the Zurich Chronic Middle Ear Inventory (ZCMEI-21)-which have become increasingly popular in recent years. OBJECTIVE: The purpose of this narrative review is to present the current state of research on measuring HRQoL in COM before and after surgical procedures. RESULTS AND CONCLUSION: Hearing is the most important factor influencing HRQoL in COM. Surgical procedures usually result in a clinically relevant improvement in HRQoL in COM with or without cholesteatoma. However, if cholesteatoma is present, its extent does not correlate with HRQoL. While HRQoL plays a secondary role in establishment of the indication for surgical therapy in COM with cholesteatoma, it plays an important role in terms of relative surgical indications, e.g., a symptomatic open mastoid cavity after resection of the posterior canal wall. We encourage the regular use of disease-specific PROMs preoperatively as well as during follow-up to assess HRQoL in COM in individual patients, in research, and in the context of quality monitoring.

PURPOSE: Evaluating the current health state in chronic otitis media (COM), audiologic results are complemented by subjective outcomes, such as health-related quality of life (HRQoL). Two disease-specific instruments assessing HRQoL in COM in German-speaking patients exist, i.e., the chronic otitis media outcome test (COMOT-15) and the Zurich chronic middle ear inventory (ZCMEI-21). Since the psychometric properties of these questionnaires in a concurrent application are unknown, the aim of this study was to compare the COMOT-15 and the ZCMEI-21. METHODS: HRQoL was assessed in adult COM patients using the COMOT-15 and the ZCMEI-21. Psychometric properties were determined, including response distribution, concurrent validity, internal consistency, correlation to hearing and gender differences. RESULTS: In 173 patients (mean age 51.5 years), both questionnaires showed normally distributed scores without strong floor and ceiling effects. The total scores and subscores of both questionnaires exhibited satisfactory internal consistency (Cronbach's α 0.7-0.9) with the exception of the COMOT-15 hearing subscore (α = 0.94) and the ZCMEI-21 medical resource subscore (α = 0.66). Fair correlations between the air conduction pure-tone average and the total scores were found (COMOT-15: r = 0.36, p < 0.0001; ZCMEI-21: r = 0.34, p < 0.0001). CONCLUSION: In the first study comparing the COMOT-15 and the ZCMEI-21, both questionnaires exhibited satisfactory psychometric properties with several subtle differences. The COMOT-15 has a strong focus on hearing with a probably redundant content of the hearing subscore and may be suited for hearing-focused research questions. The ZCMEI-21 provides a comprehensive assessment of the COM symptom complex and may therefore also be used in research settings, where ear discharge, vertigo or pain should be covered.

PURPOSE: The aim of this study was to determine whether preoperative depressive symptoms influence health-related quality of life (HRQOL) after middle ear surgery in patients with chronic otitis media (COM). METHODS: This prospective clinical case study was conducted at a tertiary referral center. All 102 patients who had undergone middle ear surgery for COM were assessed clinically and by audiometric testing (pure tone audiometry) in pre- and postoperative settings. Disease-specific HRQOL was assessed by the validated chronic otitis media outcome test 15 (COMOT-15) and the Zurich chronic middle ear inventory (ZCMEI-21). General HRQOL was measured using the short form 36 (SF-36). Depressive symptoms were assessed using the patient health questionnaire (PHQ-D). The Charlson comorbidity index (CCI) was used to classify comorbidities. The middle ear status was determined using the ossiculoplasty outcome parameter staging (OOPS) index. RESULTS: After middle ear surgery, the total COMOT-15 and ZCMEI-21 scores improved significantly (p < 0.001). General HRQOL (total SF-36 score) was unaffected by surgery (p < 0.05). Patients without elevated depressive symptoms had significantly better total scores for the COMOT-15 (p < 0.01), ZCMEI-21 (p < 0.001), and for SF-36 (p < 0.001) postoperatively. The results of the multiple regression analyses show that, after adjusting for the OOPS, CCI, and hearing improvement, preoperative depressiveness was significantly associated with worse postoperative COMOT-15 and ZCMEI-21 outcome scores (ß = 0.425 and ß = 0.362, p < 0.001). CONCLUSION: Preoperative depressiveness was an essential predictive factor for HRQOL in patients with COM. This should be considered during patient selection to provide more suitable preoperative counseling.

OBJECTIVE: To determine the relation between stapedius reflex thresholds in cochlear implant users evoked once through direct electric stimulation on single channels (ESRT) and once through acoustic stimulation in free sound field. For comparison, stapedius reflex thresholds were obtained in free sound field in a normal-hearing control group. DESIGN: For each participant a new ESRT-based fitting was created. Stapedius reflex thresholds were obtained for this new fitting in free sound field for different loudness adjustments. Acoustic stimuli for eliciting the stapedius reflex were narrow band noise signals covering the audiometric frequency range. STUDY SAMPLE: N = 29 experienced CI users (34 ears) and N = 10 normal hearing listeners. RESULTS: ESRT-based fitting resulted in different stapedius reflex behaviour compared to normal-hearing listeners. A frequency dependence was observed. Stapedius reflex thresholds decreased with increasing centre frequencies of acoustic narrow band noise stimuli. A linear relation between upper stimulation levels on the implant channels and corresponding stapedius reflex thresholds evoked in free sound field was found. CONCLUSION: The found correlation may be a guideline for adjusting the electrical dynamic range during cochlear implant fitting. This allows the implant system to mimic the natural reflex behaviour in the best possible way and potentially avoid overstimulation.

In childhood, inadequately rehabilitated hearing loss leads to impaired language acquisition and social, mental and emotional development. In adults, social withdrawal due to limited communication skills is often a consequence of unsatisfactory hearing rehabilitation. Therefore, in patients with profound hearing loss, the indication for cochlear implantation should be considered. Technical advances in cochlear implant development, as well as in microsurgical techniques and the rehabilitation process, have led to an expansion of indications in recent years. Adequate hearing rehabilitation is associated not only with an improvement in hearing function and speech understanding, but also with an increase in quality of life at all ages. In patients with unilateral profound hearing loss, cochlear implantation leads to an improvement of speech understanding and localization ability as well as to a reduction of the head shadow effect and tinnitus. The indication process, surgical treatment and the subsequent rehabilitation process require interprofessional cooperation in specialized centers.

OBJECTIVES: The use of standardized outcome parameters is essential for the comparability of clinical studies. Pure-tone audiometry and speech audiometry are widely used, but there is no systematic evaluation of the outcome parameters in clinical application. Nevertheless, there is presumably a great heterogeneity especially in the field of speech audiometry. This study presents a snapshot of the current situation of documentation and usage of outcome parameters in otologic research. STUDY DESIGN: Retrospective study of existing literature analyzing common speech audiometric test material and procedure MAIN OUTCOME MEASURES: Intervention Studies from 2012 to 2016 concerning hearing ability were eligible for evaluation. Studies were analyzed with regard to study design, pathology and intervention, speech audiometric parameters, pure-tone audiometry, implementation of reporting standards and journal related data. RESULTS: 279 studies were included. Over 50% of the analyzed studies lacked proper documentation. In the remaining studies, there was a broad variance concerning the documented speech audiometric parameters, most often with a fixed presentation level of 65 dB SPL. CONCLUSION: The lack of generally used standards for reporting hearing outcomes makes it difficult to compare results of different clinical studies. An adequate description of the methods would be a first and important step in improving reports on audiological outcomes.

When evaluating the outcome of reconstructive middle ear surgery, it is insufficient to use only the achieved improvement of audiometric measurement results. Although, as functional parameters, they occupy a central position in the therapeutic assessment of the ear as a sensory organ, they must be supplemented by a number of modern quality control factors. Different perspectives for assessment of quality must be taken into account. What is important from the patient's point of view may not be the same factors as to the physician, while the physician places a high value on factors that are less significant for the medical insurance company. The international otological community, who would like to draw conclusions from middle ear surgery data, might set different criteria altogether for assessing quality of surgery.Hence, we propose to adapt the general concept of quality to middle ear surgery. This must be implemented on different levels and surgical therapy of middle ear diseases must be understood as a process.This means that quality assessment must comprise additional aspects, which include a structured description and recording of disease-specific symptoms, findings, and outcome of treatment. Furthermore, in today's world the use of internationally recognized classification systems must be regarded as a quality feature, in order to make results not only publishable but also capable of meta-analysis. Internationally developed and recognized reporting systems are available for this purpose. Their use in routine care not only makes the collected data internationally comparable, but also enables systematic evaluation within the institution for quality description and control.In addition to audiological measurement results, surgical quality indicators are considered. We also focus on emerging complications and the value of systematic and structured evaluation and documentation systems. Validated measuring instruments are already available for patient benefit assessment, the use of which should no longer be limited to scientific studies. In summary, quality assessment of surgery should be extended to include not only the "patient as a whole", but also to the "therapy process as a whole", incorporating features of structural and process quality.
