Refractory Chronic Diffuse Granular Myringitis with Medial Meatal Stenosis.

Granular myringitis is a chronic inflammatory condition of the tympanic membrane that does not involve the middle ear. Various treatment modalities have been proposed for the treatment of granular myringitis, but there is no standard treatment regime. A 60-year-old woman had left persistent ear discharge for 4 months. Examination revealed diffuse granulation tissue, forming a pseudomembrane at the medial aspect of the ear canal and obstructing the tympanic membrane. An audiogram revealed mild-to-moderate left-sided conductive hearing loss. She was treated with multiple courses of ear drop antibiotics but had no improvement. The decision for surgical intervention was driven by the presence of a grade IV medial meatal stenosis, the potential risks associated with prolonged medical management, the distressing impact on the patient's life, and a shared decision-making process. A combined transcanal and postauricular endoscopic approach whereby excision of the granulation tissue, canalplasty, and myringoplasty were performed. She exhibited complete symptom resolution and reported an improved quality of life. This approach yielded successful symptom resolution, highlighting its potential in managing refractory chronic granular myringitis. We aimed to carefully weigh the risks of surgery against its potential benefits in a refractory chronic case, acknowledging the inherent risks and disadvantages of surgical interventions. Further studies are warranted to evaluate the long-term outcomes and benefits of this approach.

A Systematic Review of Surgical Characteristics and Adverse Events of an Active, Transcutaneous Bone Conduction Device.

OBJECTIVE: A new, active transcutaneous bone conduction device (BCD) was FDA-approved in 2019 in the USA. This systematic review sought to evaluate early outcomes associated with Osia implantation. METHODS: A systematic review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Four databases were reviewed: PubMed, Scopus, Cochrane CENTRAL, and CINAHL. Studies were included if they described audiometric, surgical characteristics/complications, or adverse events associated with the Osia BCD. Exclusion criteria: non-English language studies, animal investigations, reviews/meta-analyses, case reports, database studies. RESULTS: Eighteen studies with 336 patients were included. Mean age at implantation was 37.9 years. About 79.5% of patients had MHL/CHL and 19.5% had SSD/SHL. Mean operative time was 71.6 minutes. Mean PTA gain from unaided conditions was 35.4 dB. Mean functional gain at high frequency (6 kHz and above) from aided conditions was 16.1 dB. Mean improvement in speech recognition thresholds was 19.1 dB from unaided conditions. Adverse events (all types) were reported in 20.1% of cases. Across all studies, the postoperative infection rate was 5%. About 2% of patients reported magnet retention issues. About 1.65% of cases were complicated by hematomas. CONCLUSIONS: Under systematic literature review, the Osia BCD has been associated with low complication rates, relatively short operative times, and good audiometric and speech outcomes, notably high frequency gain >6 kHz. More advanced audiometric outcome reporting remains limited and audiometric data and patient reported outcome measures were reported heterogeneously.

Classification of ossicular fixation based on a computational simulation of ossicular mobility.

Ossicular fixation disturbs the mobility of the ossicular chain and causes conductive hearing loss. To diagnose the lesion area, otologists typically assess ossicular mobility through intraoperative palpation. Quantification of ossicular mobility and evidence-based diagnostic criteria are necessary for accurate assessment of each pathology, because diagnosis via palpation can rely on the surgeons' experiences and skills. In this study, ossicular mobilities were simulated in 92 pathological cases of ossicular fixation as compliances using a finite-element (FE) model of the human middle ear. The validity of the ossicular mobilities obtained from the FE model was verified by comparison with measurements of ossicular mobilities in cadavers using our newly developed intraoperative ossicular mobility measurement system. The fixation-induced changes in hearing were validated by comparison with changes in the stapedial velocities obtained from the FE model with measurements reported in patients and in temporal bones. The 92 cases were classified into four groups by conducting a cluster analysis based on the simulated ossicular compliances. Most importantly, the cases of combined fixation of the malleus and/or the incus with otosclerosis were classified into two different surgical procedure groups by degree of fixation, i.e., malleo-stapedotomy and stapedotomy. These results suggest that pathological characteristics can be detected using quantitatively measured ossicular compliances followed by cluster analysis, and therefore, an effective diagnosis of ossicular fixation is achievable.

The impact of the Cochlear™ Osia® 2 System on patients with mixed or conductive hearing loss: A comparison with Cochlear™ Baha® Attract System outcomes.

OBJECTIVE: This prospective study assessed the efficacy of the Cochlear™ Osia® 2 System compared to the previous Baha® Attract System in patients with mixed or conductive hearing loss (MHL/CHL). METHODS: In this prospective case-control study, 10 patients (2 men and 8 women) with MHL/CHL were implanted with the Osia® 2 System. Their audiological outcomes were compared with 13 patients (2 men and 11 women) who had previously been implanted with the transcutaneous Baha® Attract system. We compared the complications and compliance of the two groups. Also, in the Osia 2 System group, subjective satisfaction was assessed using the Korean version of the International Outcome Inventory for Hearing Aids (K-IOI-HA) questionnaire and the Abbreviated Profile of Hearing Aid Benefit (APHAB) questionnaire. RESULTS: Complications such as poor magnetization, pain & infection, and abnormal noise were more common in the Baha Attract group, although not statistically significant. Also, the Osia 2 group exhibited better compliance. Subjective satisfaction was assessed using the K-IOI-HA and APHAB questionnaires with the Osia 2 group, revealing significantly improved scores in ease of communication, reverberation, background noise, and higher K-IOI-HA scores post-implantation. Postoperative-aided thresholds with both systems were significantly lower than preoperative-unaided thresholds, with the Osia 2 System demonstrating notably high satisfaction levels. Although both systems showed similar preoperative and postoperative word-recognition scores, the Osia 2 System provided greater audiological gain, especially at 2 kHz and 4 kHz frequencies. Additionally, the functional gain of both systems was comparable across all frequencies. CONCLUSIONS: The Osia 2 System demonstrated high subjective satisfaction and improved audiological outcomes compared to the Baha Attract system in patients with conductive or mixed hearing loss. Its superior audiological gain, particularly at critical frequencies, along with better compliance, suggests it as a favorable option for this patient population.

Evaluation of Clinical Performance of Ponto Implantation Using a Minimally Invasive Surgical Technique-A Prospective Multicenter Study.

OBJECTIVE: To investigate the clinical outcomes of bone-anchored hearing implant surgery using the MONO procedure. STUDY DESIGN: Multicenter, multinational, single-arm, prospective trial with a 12-month follow-up. SETTING: Seven European university hospitals from the United Kingdom, Sweden, Denmark, and The Netherlands. PATIENTS: Fifty-one adult patients requiring surgical intervention for bone conduction hearing. INTERVENTION: Bone-anchored hearing implant surgery using the MONO procedure. MAIN OUTCOME MEASURES: The primary endpoint assessed implant usability 3 months after surgery. Implant status, soft tissue reactions, pain and numbness, postoperative events, and sound processor usage were assessed at all follow-up visits. Hearing-related quality of life was evaluated using the Glasgow Benefit Inventory (GBI). RESULTS: At 3 months, 94.2% of the implant/abutment complexes provided reliable anchorage for sound processor usage. No severe intraoperative complications occurred. Sixty-nine percent of surgeries were performed under local anesthesia, with surgery lasting 10 minutes on average. Four implants were lost due to trauma (n = 2), spontaneous loss of osseointegration (n = 1), or incomplete insertion (n = 1). Adverse soft tissue reactions occurred in 2.6% of visits, with a maximum Holgers grade of 3 (n = 1) and grade 2 (n = 5) across patients. Hearing-related quality of life at 3 months improved in 96% of patients. CONCLUSION: The MONO procedure provides a safe and efficient surgical technique for inserting bone-anchored hearing implants with few and minor intra- and postoperative complications.

Beyond the surface: exploring contributing factors to bone anchored hearing implant complications.

INTRODUCTION: Bone anchored hearing implants (BAHI) are considered for conductive and mixed hearing loss, relying on osseointegration of a titanium implant. Limitations relate to constant skin contact, with resultant percutaneous infections and granulation. This study investigates whether patient characteristics and implant-specifications contribute to BAHIs' skin complications in a cohort with a uniform surgical approach. METHODS: A 10 year (2014-2024) retrospective cohort study was conducted on BAHI procedures that were undertaken using a tissue-preserving 'punch' technique. Data on patient demographics, co-morbidities, implant type, surgical approach, and complications were collected. Poisson regression analysis was used to identify predictors of complications. RESULTS: A total of 53 patients undergoing 55 BAHI surgeries by three ENT consultants were included. Factors that greatly increased implant-related percutaneous infections included the Cochlear™ BIA400 implant when compared to the Ponto™ BHX implant (twofold, CI 2.03-2.16), abutment sizes ≤ 10 mm (fourfold, CI 3.99-4.12) and male gender (9%, CI 1.07-1.12). Granulation episodes were affected by cardiovascular disease (CVD) status (1.5-fold, CI 0.26-0.78), BIA400 implant (threefold, CI 8.8.-9.2) and abutment sizes ≤ 10 mm (fourfold, CI 3.6-3.73). Revision surgery episodes increased with diabetic status (1.2-fold, CI 0.06-0.37) and abutment sizes ≤ 10 mm (threefold, 3.303-3.304). CONCLUSIONS: Larger cohort studies are required to confirm findings, particularly for implant and abutment size contributions. However, the findings suggest that using a larger abutment size when skin thickness meassuremets are borderline, improved hygiene education in male patients, pre-operative optimisation of CVD and diabetes, and adjusted patient follow-up based on risk stratification of the contributing factors to complication rates could reduce complication rates.

Conductive Hearing Loss Associates With Dementia, and Middle Ear Reconstruction Mitigates This Association: A Multinational Database Study.

OBJECTIVE: To test the hypothesis that conductive hearing loss (CHL) is associated with dementia, and that middle ear reconstruction (MER) associates with improved outcomes for these measures in a multinational electronic health records database. STUDY DESIGN: Retrospective cohort study with propensity-score matching (PSM). SETTING: TriNetX is a research database representing about 110 million patients from the United States, Taiwan, Brazil, and India. PATIENTS: Subjects older than 50 years with no HL and any CHL (ICD-10: H90.0-2). Subjects of any age with and without any MER (CPT: 1010174). MAIN OUTCOME MEASURES: Odds ratios (ORs) and hazard ratios with 95% confidence intervals (95% CIs) for incident dementia (ICD-10: F01, F03, G30). RESULTS: Of 103,609 patients older than 50 years experiencing any CHL, 2.74% developed dementia compared with 1.22% of 38,216,019 patients with no HL (OR, 95% CI: 2.29, 2.20-2.37). Of patients experiencing CHL, there were 39,850 who received MER. The average age was 31.3 years, with 51% female patients. A total of 343,876 control patients with CHL were identified; 39,900 patients remained in each cohort after 1:1 PSM for HL- and dementia-related risk factors. Matched risk for developing dementia among MER recipients was 0.33% compared with 0.58% in controls (OR: 0.58, 0.46-0.72). CONCLUSIONS: CHL increases the odds for dementia, and MER improves the odds for incident dementia. This study represents the first population study on the topic of CHL, MER, and dementia.

Feasibility and Outcomes of an Active Osseointegrated Bone Conduction Implant in Children as Young as 5 Years of Age.

INTRODUCTION: This study reviews the feasibility of implanting active osseointegrated bone conduction devices in young children, below the prior age for FDA indication (<12 years), which has recently been reduced to 5 years. Outcomes included differences in adverse event rates and operative time between two groups (<12 and 12 years or older). MATERIALS AND METHODS: This study is a retrospective review of children receiving active osseointegrated bone conduction devices at a tertiary referral center academic hospital. One hundred and twenty-four children received 135 active osseointegrated bone conduction devices (May 2018-March 2024). RESULTS: Of 135 devices, 77 (57%) were in children <12 years (mean age (SD) = 7.9 (2.0) years, range = 4.9-11.9 years) and 58 (43%) were in 12 years or older (mean age (SD) = 15.1 (1.7) years, range = 12-18 years). Adverse events were significantly higher in the older group, occurring in 8 (10%) of 77 devices in children <12 years and 15 (26%) of 58 devices in children 12 years and older (26%) (Fisher's exact test = 0.0217 at p < 0.05). Major adverse events occurred in 5/124 (4%) patients, with 2 in patients <12 years (2/73, 3%) and 3 in children 12 and older (3/51, 6%). The proportion of major events between groups was not significantly different (Fisher's exact test = 0.4, p < 0.05). Mean surgical time was significantly less (t = -2.8799, df = 120.26, p = 0.005) in the children <12 years (mean (SD) = 66.5 (22.4) min) compared to those 12 and over (mean (SD) = 78.32 (23.1) min). CONCLUSIONS: Implantation of active osseointegrated bone conduction devices is feasible in children as young as 5 years and demonstrates low rates of complication. Further miniaturization may allow even earlier safe intervention.

The Merits of Bilateral Application of Middle Ear Implants in Patients With Bilateral Conductive and/or Mixed Hearing Loss.

This study investigated sound localization abilities in patients with bilateral conductive and/or mixed hearing loss (BCHL) when listening with either one or two middle ear implants (MEIs). Sound localization was measured by asking patients to point as quickly and accurately as possible with a head-mounted LED in the perceived sound direction. Loudspeakers, positioned around the listener within a range of +73°/-73° in the horizontal plane, were not visible to the patients. Broadband (500 Hz-20 kHz) noise bursts (150 ms), roved over a 20-dB range in 10 dB steps was presented. MEIs stimulate the ipsilateral cochlea only and therefore the localization response was not affected by crosstalk. Sound localization was better with bilateral MEIs compared with the unilateral left and unilateral right conditions. Good sound localization performance was found in the bilaterally aided hearing condition in four patients. In two patients, localization abilities equaled normal hearing performance. Interestingly, in the unaided condition, when both devices were turned off, subjects could still localize the stimuli presented at the highest sound level. Comparison with data of patients implanted bilaterally with bone-conduction devices, demonstrated that localization abilities with MEIs were superior. The measurements demonstrate that patients with BCHL, using remnant binaural cues in the unaided condition, are able to process binaural cues when listening with bilateral MEIs. We conclude that implantation with two MEIs, each stimulating only the ipsilateral cochlea, without crosstalk to the contralateral cochlea, can result in good sound localization abilities, and that this topic needs further investigation.

[Analysis of the efficacy of fiber laser stapes fenestration in the treatment of 58 cases of otosclerosis and ossicular malformation].

Objective: To explore the surgical efficacy of conductive deafness caused by otosclerosis and ossicular malformation with 980 nm fiber laser stapedial floor fenestration. Methods: Data of 58 patients (ears) who were diagnosed with conductive deafness caused by otosclerosis (49 ears) and ossicular malformation (9 ears) treated by 980 nm Diode laser small-fenestra stapedotomy were retrospectively analyzed. Air conduction (AC) thresholds, bone conduction (BC) thresholds, and air-bone gap (ABG) at 0.5, 1, 2, 4 kHz pure tone frequencies were compared before and 3 months after surgery, and the advantages and precautions of 980 nm fiber laser were summarized. Paired t-test (SPSS 26.0 software) was use to analyze the listening data. Results: Fiber optic laser stapes fenestration and artificial stapes implantation were successfully completed in all 57 cases (ears), the hearing of another one patient (ear) with floating malformation of detachment of stapedial floor was lower than that before surgery. Preoperative at 0.5, 1, 2, 4 kHz frequencies of AC thresholds, BC thresholds, and ABG were (65.4±9.7) dB, (27.2±8.9) dB, and (38.2±9.8) dB respectively. Postoperative 3 months at the same frequency of AC thresholds, BC thresholds, and ABG were (42.1±11.3) dB, (26.9±6.6) dB, and (15.2±9.1) dB. Preoperative and postoperative of AC threshold and ABG were statistically significant at 0.5, 1, 2, 4 kHz (t value was 13.270 and13.948, both P<0.01), and yet the BC threshold was not statistically significant before and after surgery at the same frequency (t=0.418, P>0.05). Conclusions: 980 nm fiber laser stapes floor fenestration is an effective treatment for conductive deafness caused by otosclerosis and ossicular malformation.

[An unusual case: fracture of the handle of the malleus due to finger manipulation]. / Ein ungewöhnlicher Fall: Fraktur des Hammergriffs durch Fingermanipulation.

An isolated fracture of the handle of the malleus is a rare entity in otorhinolaryngology and manifests clinically as acute-onset unilateral hearing loss. Several factors may cause this injury, including acute barotraumatic pressure changes or traumatic events. Various therapeutic approaches such as tympanoplasty, autologous graft, or application of bone cement are discussed. We report the case of a 46-year-old female patient who developed acute hearing loss in her left ear after finger manipulation. Clinical evaluation revealed axial displacement of the handle of the malleus and audiometry indicated conductive hearing loss. After otoscopy, audiometry, and computed tomography, tympanoscopy was indicated due to suspicion of ossicular chain disruption. Intraoperatively, an isolated fracture of the handle of malleus was found, which was treated with glass ionomer cement. Following postoperative examination, there was progressive improvement in the acoustic transmission component, such that a normal hearing threshold was observed 4 months postoperatively. This case report underlines the importance of precise diagnosis and individualized treatment for rare middle ear injuries.

Audiological outcomes after revision stapes surgeries: a systematic review.

PURPOSE: Revision stapes surgery is a challenging procedure performed in relatively small numbers compared to other middle ear procedures. Despite numerous data on hearing results of different middle ear surgeries, the audiological standards for successful outcome of this procedure are still not clarified. On the basis of well-documented data, we wanted to determine what the expected audiological results and complications are after revision stapes surgery in order to set a realistic threshold for surgical success. METHODS: After the protocol registration in the PROSPERO database, a systematic review was performed in multiple databases (PubMed, Cochrane, Web of Science, Scopus, ScienceOpen, ClinicalTrials.gov, Google Scholar) according to PRISMA guidelines. Twelve articles were reviewed according to the inclusion criteria. A total of 1032 cases were obtained for evaluation. A modified version of Newcastle-Ottawa Scale (NOS) was used to assess publication quality. RESULTS: Average air-bone gap (ABG) gain was 17.3 dB, average air conduction (AC) gain was 17.5 dB. The average postoperative air-bone gap was 11.1 dB. The postoperative ABG distribution was the following 0-10 dB: 53.3%, > 10-20 dB: 28.2%, > 20 dB: 18.5%. SNHL as a surgical complication was described in a total of 17 cases (1.6%), no equilibrium disorder was reported. CONCLUSION: The pooled data suggest that revision stapes surgery is an effective solution after failure of previous stapes surgery. However, the results are clearly inferior to those of primary stapedotomies. Hence, we need to apply different expectations and use different standards in the indication and evaluation of this type of surgery.

Bone mineral density of the incus body and long process in patients with chronic otitis media and its relationship with functional outcome in type II tympanoplasty.

BACKGROUND: Inflammatory conditions such as chronic otitis media (COM) can cause irreversible impairments in the microarchitecture and functions of the incus, which subsequently leads to conductive hearing loss. OBJECTIVES: To investigate bone mineral density (BMD) of the incus body (IB) and long process (ILP) on preoperative temporal CT in COM patients with and without incudo-stapedial joint discontinuity (ISJD), and also to determine the association between BMD values and the postoperative air-bone gap (ABG) in the ISJD group. MATERIAL AND METHODS: The mean IB density (IBD)/occipital bone density (OBD) and ILP density (ILPD)/OBD values were compared between the patients with and without ISJD. The correlation between ABG gain and preoperative incus density values was assessed in the ISJD group. RESULTS: The mean IBD/OBD and ILPD/OBD values were significantly higher in patients with intact ISJ. There was a moderate positive correlation between postoperative ABG gain and ILPD/OBD values in the ISJD group. CONCLUSION AND SIGNIFICANCE: The decrease in BMD of the incus may involve ILP as well as IB in patients with ISJD caused by ILP lysis in COM. A higher preoperative ILPD/OBD was correlated with a higher postoperative ABG gain in COM patients with ISJD.

Staged implantation of active transcutaneous bone conduction hearing devices (BCHD) after explantation of older generation bone anchored hearing aids (BAHAs): Surgical outcomes and approach to management.

PURPOSE: To evaluate outcomes following explantation of percutaneous or transcutaneous bone conduction implants (pBCIs or tBCIs) and subsequent implantation of transcutaneous active bone conduction hearing devices (BCHDs); to provide guidance regarding staging of surgery and adjunctive procedures. MATERIALS AND METHODS: Retrospective chart review of eight adult subjects (ten ears) with pBCIs or tBCIs who underwent explantation of their device and subsequent implantation with a BCHD [MED-EL BONEBRIDGE™ (n = 7, 70 %) or Cochlear™ Osia® (n = 3, 30 %)]. RESULTS: Reasons for pBCI or tBCI explantation were pain (60 %, 6/10), infection (60 %, 6/10), skin overgrowth (50 %, 5/10), and inability to obtain new processors (20 %, 2/10). Median time between pBCI or tBCI removal and BCHD staged implant was 4.7 (IQR 2.2-8.1) months. Two subjects developed complications following BCHD implantation. One had a persistent wound overlying the osseointegrated screw after removal of the pBCI abutment, requiring removal and temporalis rotational flap. Staged Osia® implantation was performed, but ultimately wound dehiscence developed over the device. The second subject experienced an infection after BONEBRIDGE™ implantation (32 days after pBCI explant), necessitating washout and treatment with intravenous antibiotics. There was subsequent device failure. CONCLUSION: The transition from a pBCI or tBCI to a novel transcutaneous device is nuanced. Staged pBCI or tBCI explantation and novel BCHD implantation with sufficient time for wound healing is vital. Adjunctive procedures to augment soft tissue in cases of prior attenuation may be required to avoid complications with larger internal devices.

Clinical Outcomes of an Active, Transcutaneous, Bone Conduction Hearing Device: A Retrospective Study.

OBJECTIVE: The purpose of this study was to review patient demographics, indications, intraoperative findings, complications/adverse events, and audiological outcomes related to the implantation of the Osia 2 device. STUDY DESIGN: Retrospective case series. SETTING: Single tertiary institutional experience. METHODS: Patients who had undergone Osia 2 implantation by the senior author were identified from 2019 to present. Information was extracted from patient charts concerning patient demographics, indications for implantation, surgical findings, audiological outcomes, and adverse events. RESULTS: Sixty patients and 67 implants were included. The median age was 51 years (R: 11-92). Fifty-five percent of patients had mixed hearing loss (HL), 30% had single-sided deafness, and 15% had conductive HL. The mean operative time was 53.9 minutes. Only 4.5% of patients required bone polishing, and 3.0% required tissue thinning. The mean pure-tone averages 4 gain from unaided conditions was 41.2 dB. Mean gain at 6 and 8 kHz from unaided conditions was 35.42 and 40.67 dB, respectively. Mean improvement in speech recognition threshold and word recognition score was significant in noise and quiet conditions. The all-cause adverse event/complication rate in our series was 10.4%. The most common complications were infections (4.5%) and poorly controlled postoperative pain (3.0%). Hematomas occurred in 1.5% of patients. Reoperation was required in 4 patients; explant in 1. CONCLUSION: Use of the Osia 2 device in our series has resulted in good hearing outcomes, particularly in terms of high frequency gain. Complication rates were low. To our knowledge, this is the largest study to date reporting on Osia 2 outcomes.

The presence of a submucous cleft palate in patients with isolated cleft lip and middle ear dysfunction.

PURPOSE: Recent studies have suggested that children with an isolated cleft lip (CL) are more likely to develop middle ear disease and eustachian tube dysfunction (ETD) compared to the general population. This may be related to abnormal palatal musculature or an undiagnosed submucosal cleft palate (SMCP). We aim to determine the prevalence of SMCP in patients with CL who exhibit ETD. MATERIALS AND METHODS: A retrospective chart review was performed for children with an isolated CL requiring tympanostomy tubes over a 20-year period at an academic tertiary care medical center. Demographic, clinical, and surgical data were collected. RESULTS: Three hundred twelve patients had an isolated CL, and 29 (9.3 %) children required tympanostomy tubes. Of those, nine (31 %) were found to have a SMCP (7 males, 6 Caucasian). The average age at CL repair was 3.94 ± 1.03 months, and the average age at tympanostomy tube placement was 13.68 ± 13.8 months. All nine patients had chronic otitis media, with four having mild conductive hearing loss and three having moderate conductive hearing loss. The SMCP was diagnosed at the time of CL diagnosis (4), after CL diagnosis with the diagnosis of chronic otitis media/ETD (2) and after a diagnosis of chronic otitis media/ETD. CONCLUSION: Middle ear disease or eustachian tube dysfunction in a patient with an isolated cleft lip should raise suspicion for an accompanying undiagnosed SMCP.

Binaural hearing in monaural conductive or mixed hearing loss fitted with unilateral Bonebridge.

Objective: To determine the benefits of binaural hearing rehabilitation in patients with monaural conductive or mixed hearing loss treated with a unilateral bone conduction implant (BCI). Methods: This monocentric study includes 7 patients with monaural conductive or mixed hearing loss who underwent surgical implantation of a unilateral BCI (Bonebridge, Med-El). An ITA Matrix test was performed by each patient included in the study - without and with the BCI and in three different settings - to determine the summation effect, squelch effect and head shadow effect. Subjective hearing benefits were assessed using the Abbreviated Profile of Hearing Aid Benefit (APHAB) questionnaire. Results: The difference in signal to noise ratio of patients without and with BCI was 0.79 dB in the summation setting (p < 0.05), 4.62 dB in the head shadow setting (p < 0.05) and 1.53 dB (p = 0.063) in the squelch setting. The APHAB questionnaire revealed a subjective discomfort in the presence of unexpected sounds in patients using a unilateral BCI (aversiveness score) compared to the same environmental situations without BCI, with a mean discomfort score of 69.00% (SD ± 21.24%) with monaural BCI versus 25.67% (SD ± 16.70%) without BCI (difference: -43.33%, p < 0.05). In terms of global score, patients wearing a unilateral Bonebridge implant did not show any significant differences compared to those without hearing aid (difference: -4.00%, p = 0.310). Conclusions: Our study shows that the use of a unilateral BCI in patients affected by monaural conductive or mixed hearing loss can improve speech perception under noise conditions due to the summation effect and to the decrease of the head shadow effect. However, since monaural BCIs might lead to discomfort under noise conditions in some subjects, a pre-operative assessment of the possible individual benefit of a monaural BCI should be carried out in patients affected by unilateral conductive or mixed hearing loss in order to investigate the possible additional effect of the fitting of hearing aids.

Efficacy of vibrant sound bridge in congenital aural atresia: an updated systematic review.

PURPOSE: The indications of Vibrant Soundbridge (VSB) have been expanded to include patients with conductive and mixed hearing loss due to congenital aural atresia (CAA). However, the current evidence supporting the auditory outcomes of VSB is based mainly on case reports and retrospective chart reviews. Therefore, the present systematic review aims to summarize and critically appraise the current evidence regarding the safety and effectiveness of VSB in children and adult patients with CAA. METHODS: A systematic literature search retrieved studies that evaluated the outcomes of unilateral or bilateral implantation of VSB in patients with CAA. The bibliographic search was conducted in PubMed, Scopus, EBSCO, and Cochrane Central Register of Controlled Trials (CENTRAL) databases from January 2000 to December 2022. RESULTS: Twenty-seven studies were included in the present systematic review. Overall, the speech perception after VSB was good, with a mean word recognition score (WRS) score ranging from 60 to 96.7%. The mean postoperative speech recognition threshold (SRT) after implantation ranged from 20.8 to 50 dB. The effective gain was reported in 15 studies, ranging from 31.3 to 45.5 dB. In terms of user satisfaction with VSB, the included studies showed significant improvements in the patient-reported outcomes, such as the Speech Spatial and Qualities of Hearing scale and Glasgow Hearing Aid Benefit Profile. The VSB implantation was generally safe with low incidence of postoperative complications. CONCLUSION: VSB provides significant benefits to individuals with hearing loss owing to CAA, with very good subjective outcomes and a low risk of complications.

Congenital Absence of Stapes Suprastructure and Footplate: A Case Report.

INTRODUCTION: Congenital ossicular chain anomalies are rare conductive hearing loss conditions that remain difficult to diagnose even with high-resolution computed tomography (CT). The preoperative diagnosis is helpful for surgical planning and counseling patients regarding treatment outcomes. CASE PRESENTATION: We report a case involving a 14-year-old boy presenting with left conductive hearing loss without history of trauma for 5 years, physical examination showed normal otoscopic examination bilaterally and high-resolution CT showed absent of stapes suprastructure and footplate. Subsequent diagnosis was done via endoscopic middle ear exploration which revealed an absent long process of the incus, stapes suprastructure and footplate, but with intact oval window membrane. The residual incus was removed, and a tragal perichondrium graft was used over the oval window. A total ossicular replacement prosthesis was placed between the malleus and oval window to repair the chain. Postoperatively, the patient had no complications. Preoperative pure tone average revealed an air/bone result of 52/8 dB. Follow-up after surgery at 6 months showed a pure tone average air/bone result of 15/3 dB. The air-bone gap was reduced from 44 to 12 dB. CONCLUSION: Congenital absence of the stapes suprastructure and footplate remains a rare condition compared to the myriad of middle ear anomalies in the literature.
