Background: A bone conducting implant is a treatment option for individuals with conductive or mixed hearing loss (CHL, MHL) who do not tolerate regular hearing aids, and for individuals with single-sided deafness (SSD). An active bone conducting implant (ABCI) was introduced in 2012 with indication in CHL, MHL, and SSD, and it is still the only ABCI available. With complete implantation of the active transducer and consequent intact skin, a decrease in infections, skin overgrowth, and implant losses, all common disadvantages with earlier passive bone conducting implants, could be expected. Our Ear, Nose and Throat Department, a secondary care center for otosurgery that covers a population of approximately 365,000 inhabitants, was approved to implant ABCIs in 2012. Objectives: Our aim was to conduct an evaluation of audiological and subjective outcomes after ABCIs. Method: A cohort study with retrospective and prospective data collection was performed.The first 20 consecutive patients operated with an ABCI were asked for informed consent. The main outcome measures werepure tone and speech audiometry and the Glasgow Benefit Inventory (GBI). Results: Seventeen patients accepted to participate and 15 were able to complete all parts. Six patients had CHL or MHL. In this group the pure tone audiometry tests are comparable with an average functional hearing gain of 29.8 dB HL. With bilateral hearing, the mean Word Recognition Score (WRS) in noise was 35.7% unaided and 62.7% aided. Ten patients had the indication SSD. With the hearing ear blocked, the pure tone average was >101 dB HL, compared to 29.3 dB HL in sound field aided. With bilateral hearing, the mean WRS in noise was 59.7% unaided and 72.8% aided. The mean of the total GBI score was 42.1 in the group with CHL or MHL and 20.6 in the group with SSD. Conclusions: The patients benefit from their implants in terms of quality of life, and there is a substantial hearing gain from the implant for patients with conductive or MHL. Patients with SSD benefit less from the implant than other diagnoses but the positive outcomes are comparable to other options for this group.

Purpose: Chronic rhinosinusitis (CRS) is related to asthma and chronic obstructive pulmonary disease (COPD). However, combined data on CRS, pulmonary function, lower airway symptoms, and cigarette smoking from the general population are lacking. The current study investigates the relationships between CRS and chronic airflow limitation (CAL), lower airway symptoms and COPD in a middle-aged population of ever-smokers and never-smokers. Patients and Methods: All subjects from the Swedish CArdioPulmonary bioImage Study (SCAPIS) were included. Subjects underwent spirometry after bronchodilation. Chronic airflow limitation was defined as FEV₁/FVC ratio < 0.7. Computed tomography imaging of the thorax was performed to detect the presence of emphysema, and the subjects answered a comprehensive questionnaire on CRS, lower airway symptoms, asthma, chronic bronchitis, and cigarette smoking habits. Results: In total, 30,154 adult subjects in the age range of 50– 64 years were included. The prevalence of CRS was 5.6%. CRS was more-prevalent among subjects in the following categories: CAL (7.6%), lower airway symptoms (15.7%), current smokers (8.2%), asthma (13.6%), never-smokers and ever-smokers with COPD (17.6% and 15.3%, respectively), emphysema (6.7%), and chronic bronchitis (24.5%). In the adjusted regression model, CRS was significantly associated with CAL (OR 1.40), lower airway symptoms (OR 4.59), chronic bronchitis (OR 6.48), asthma (OR 3.08), and COPD (OR 3.10). Conclusion: In this national, randomly chosen population sample of more than 30,000 middle-aged men and women, CRS is associated with CAL, lower airway symptoms, chronic bronchitis, asthma, and COPD. In patients with CRS and in patients with lower airway inflammation, it is important to consider the inflammatory status of the entire airway system.

Objective: To evaluate long-term outcomes of active transcutaneous bone conduction implants (atBCIs) regarding safety, hearing, and quality of life. Study design: A clinical study with retrospective medical record analysis combined with prospective audiometry and quality of life questionnaires. Setting: Three secondary to tertiary care hospitals. Patients: All subjects operated with an atBCI in three regions in Sweden were asked for informed consent. Indications for atBCI were single-sided deafness (SSD) and conductive or mixed hearing loss (CMHL). Intervention: Evaluation of atBCI. Main Outcome Measures: Pure tone and speech audiometry and Glasgow Benefit Inventory (GBI). Result: Thirty-three subjects were included and 29 completed all parts. The total follow-up time was 124.1 subject-years. Nineteen subjects had CMHL and in this group, pure tone averages (PTA4) were 56.6 dB HL unaided and 29.6 dB HL aided, comparable with a functional gain of 26.0 dB. Effective gain (EG) was −12.7 dB. With bilateral hearing, Word Recognition Scores (WRS) in noise were 36.5% unaided and 59.1% aided. Fourteen subjects had SSD or asymmetric hearing loss (AHL) and in this group, PTA4 were >100 dB HL unaided and 32.1 dB HL aided with the contralateral ear blocked. EG was −9.1 dB. With bilateral hearing, WRSs were 53.2% unaided and 67.9% aided. The means of the total GBI scores were 31.7 for CMHL and 23.6 for SSD/AHL. Conclusion: Few complications occurred during the study. The atBCI is concluded to provide a safe and effective long-term hearing rehabilitation.

Hearing loss is the third most significant cause of disability globally and is associated with anxiety, depression, loneliness, and cognitive decline. For those unable to utilize conventional hearing aids due to conditions such as ear canal atresia, eczema, recurrent external otitis or extensive ear surgery, implantable hearing aids provide an alternative. This narrative review provides an overview of available bone conduction devices and active middle ear implants. The rapid advancements in implantable hearing aid technology necessitate ongoing education of healthcare professionals to enable informed patient decisions.

Subglottic stenosis (SGS) is a narrowing of the airway just below the vocal folds. The cause of SGS and the optimal care for these patients, have remained elusive. Endoscopic surgery of SGS using either balloon or CO₂ laser is associated with recurrence. Our aim is to compare surgery free intervals (SFI) between these two methods applied in two different timeframes. The knowledge gained from this project can support decision-making regarding surgical method choice. Participants were retrospectively identified using medical records between 1999 - 2021. We used pre-defined broad inclusion criteria to identify cases using the International Classification of Disease (ICD-10). Primary outcome was surgery free intervals. 141 patients were identified, 63 met the criteria for SGS, and were included in the analysis. Results show no significant difference in SFI, comparing balloon dilatation and CO₂ laser. These findings demonstrate no detected difference in treatment intervals (SFI) when comparing these two commonly used surgical alternatives for SGS. The outcome of this report supports surgical freedom of choice based on the surgeon's experience and skill and ushes for further studies on patient experience regarding these two therapeutic approaches.

Background: LHX3 is a gene encoding a LIM-homeodomain transcription factor important for the fetal development of several organs, such as the pituitary gland, spinal motor neurons and the inner ear. Pathogenic and likely pathogenic variants in the LHX3 gene are infrequent and result in a rare syndrome known as combined pituitary hormone deficiency-3, CPHD3. Methods: We have studied hearing and vestibular functions in a group of eight individuals, aged 8–36 years, all of whom were homozygous for a specific variant in the LHX3 gene at chromosome 9q34. We reexamined the results of consecutive hearing tests from newborn until April 2024. Results: Our data showed that all the tested patients had progressive sensorineural hearing deficiency ranging from moderately severe to complete loss. We have performed vestibular testing in six patients and, for the first time, demonstrated that a mutation in the LHX3 gene not only affects hearing, but is also associated with vestibular impairment. Conclusion: The human pathogenic variant c.455-2A > G in the LHX3 gene on chromosome 9q34, which present as a founder mutation in the population in northern Sweden, is responsible for phenotypes associated with progressive hearing loss and balance impairment. These findings prove that the LHX3 gene is crucial for the function of both the cochlear and vestibular organs.
