BACKGROUND: The Otology Questionnaire Amsterdam (OQUA) is developed to evaluate multiple ear complaints and their impact on patients\' daily lives. The current clinical use of this questionnaire is below the potential utilization.
OBJECTIVE: To identify the barriers and enablers of using the OQUA as perceived by ENT surgeons and patients and provide recommendations for an implementation strategy.
METHODS: Prospective and qualitative analysis was performed using focus groups and interviews with ENT professionals (n = 15) and patients (n = 25) with ear complaints of one tertiary referral hospital and two regional hospitals. Barriers and enablers were identified and classified by using the Capability-Opportunity-Motivation-Behavior model and the Theoretical Domains Framework. Suggestions for an implementation strategy will be made accordingly.
RESULTS: ENT professionals\' barriers included lack of knowledge and skills to use the OQUA, inadequate technological support and perceived time constraints during consultation, uncertainty about the clinical relevance and lack of feedback on the outcomes of the OQUA. Enablers included beneficial consequences of the OQUA for the professional, organization and science. Patients\' barriers included lack of knowledge about the objective and usefulness of the OQUA, perceived burden, difficulties in completing the questionnaire and insufficient feedback during consultation. Patient enablers included beliefs about beneficial consequences of the OQUA for the patient, health care and society. Suggested interventions involved education, training, environmental restructuring and incentivisation.
CONCLUSIONS: Based on the findings, we propose an implementation strategy should focus on education and training about the objective, outcomes and relevance of the OQUA, environmental restructuring regarding the optimal use of the OQUA, and incentivisation with feedback on the valuable outcomes of the OQUA for the patient, professional and healthcare. Future research is needed to determine the feasibility of the implementation strategy.

BACKGROUND: Pathway innovation using smartphone otoscopy and tablet-based audiometry technologies to deliver ear and hearing services via trained audiologists may improve efficiency of the service. An ENT-integrated-community-ear service (ENTICES-combining community audiology management, remote ENT review and novel technologies) was piloted. We aimed to assess the efficiency and safety of ENTICES.
METHODS: ENTICES was a community-based and audiologist-led pathway. Patients with otological symptoms were self-referred to this service. Smartphone otoscopy and tablet-based audiograms were performed. Two otologists reviewed all decisions made in the community by audiologists based on video-otoscopy, hearing tests and chart reviews. Data on the first 50 consecutive new patients attending either consultant-led hospital otology clinics (HOC), audiologist-led hospital advanced audiology diagnostics (AAD) or ENTICES clinics were collected between 1 August 2021 and 31 December 2021. Data were collected through chart reviews and questionnaires to compare the three pathways with respect to efficiency, patient satisfaction, technology utility and safety.
RESULTS: No audiology-led ENTICES decisions were amended by hospital otologists following remote review. Remote review of video-otoscopy with history was sufficient for a diagnosis in 80% of cases. Adding hearing tests and standardised history increased the diagnostic yield to 98%. Patient satisfaction scores showed 100% service recommendation. The cost per patient, per visit, was £83.36, £99.07 and £69.72 for AAD, HOC or ENTICES, respectively.
CONCLUSIONS: ENTICES provides a safe ear and hearing service that patients rated highly. Thirty-two per cent of hospital otology patients were eligible for this service. For those patients, ENTICES is 20% more cost-effective and can reduce the number of clinic visits by up to 60% compared with HOC.

OBJECTIVE: Otological symptoms (OS) are highly prevalent in individuals with temporomandibular disorders (TMD). Individuals with TMD and OS have more neck disability and decreased deep neck muscles endurance when compared to individuals without OS. However, no studies have evaluated whether OS is associated with lower Quality of Life (QoL) and worse levels of physical activity. This study aimed to evaluate the QoL and level of physical activity of individuals with TMD with and without OS.
METHODS: In this cross-sectional study, 62 individuals with TMD were allocated into 2 groups: TMD with OS (n = 36) or TMD without OS (n = 26). Self-reported complaints of dizziness, vertigo, tinnitus, earache, ear fullness, or hypoacusis were considered as OS. QoL was assessed with the WHOQOL-Bref and physical activity with the IPAQ-SF. Independent t-test and chi-squared test were used for analysis between-groups. Effect sizes were reported using Cohen\'s d. A Pearson correlation was used to compare the number of OS and QoL scores. A significance level of p < 0.05% and 95% confidence intervals were considered statistically significant.
RESULTS: The total generic scores for QoL were not different between-groups (p = 0.076), but individuals with TMD with OS had lower satisfaction (p = 0.015; d: 0.63) and physical domain (p = 0.015; d: 0.64) scores with a moderate effect size. In TMD with OS, 69.4% of individuals were irregularly active and 50% for the TMD without OS, with no statistical significance (p > 0.05). The number of OSs was inversely and weakly associated with the QoL total score.
CONCLUSIONS: Individuals with TMD and OS are associated with worsened QoL (physical domain and satisfaction) when compared to individuals with TMD without OS. The higher the number of OS, the worse the QoL score. Individuals with TMD with and without OS had similar levels of physical activity, but a high prevalence of irregularly active and sedentary individuals within TMD diagnosed population was found.

OBJECTIVE: Barochallenge-induced Eustachian tube dysfunction (ETD) is difficult to diagnose because the examination is often normal during clinical assessment. In adults, functional tympanometry testing, performed by asking the patient to Valsalva and Toynbee while measuring the pressure shift, can aid in the diagnosis of ETD. However, standardized values do not exist in children. We aim to determine the age at which children can perform these maneuvers and the normative values in this population.
METHODS: Patients with a normal basic ear examination 4 years and older, presenting to the pediatric Otolaryngology clinic, were recruited. Otoscopy, baseline tympanometry, followed by Valsalva and Toynbee maneuvers were performed. Because there are no pediatric norms, we hypothesized that children would achieve the same minimum normal pressure shift as cited in the adult literature (+20 daPa or higher for Valsalva and -20 daPa or lower for Toynbee). The data were analyzed using receiver operating characteristic curves and logistic regression.
RESULTS: One hundred sixty-eight children (276 ears) were assessed. Participants as young as 4 years old were able to perform a Valsalva and Toynbee. Age cut-offs at which children achieved adult norms were 12.5 years ( p = 0.016) and 8.5 years ( p = 0.071) for Valsalva and Toynbee maneuvers, respectively. Mean pressure shift ranged from +29 to -36 daPa, and males were 2.5 times more likely to achieve Toynbee compared with females ( p = 0.006).
CONCLUSIONS: Functional tympanometry testing may be used to help diagnose barochallenge-induced ETD in older children.

To explore the views of parents and carers regarding the management of acute otitis media in urban Aboriginal and Torres Strait Islander children who are at low risk of complications living in urban communities.
Qualitative study; semi-structured interviews and short telephone survey.
Interviews: purposive sample of parents and carers of urban Aboriginal and Torres Strait Islander children (18 months - 16 years old) screened in Aboriginal medical services in Queensland, New South Wales, and Canberra for the WATCH study, a randomised controlled trial that compared immediate antibiotic therapy with watchful waiting for Aboriginal and Torres Strait Islander children with acute otitis media.
parents and carers recruited for the WATCH trial who had completed week two WATCH surveys.
We interviewed twenty-two parents and carers, including ten who had declined participation in or whose children were ineligible for the WATCH trial. Some interviewees preferred antibiotics for managing acute otitis media, others preferred watchful waiting, expressing concerns about side effects and reduced efficacy with overuse of antibiotics. Factors that influenced this preference included the severity, duration, and recurrence of infection, and knowledge about management gained during the trial and from personal and often multigenerational experience of ear disease. Participants highlighted the importance of shared decision making by parents and carers and their doctors. Parents and carers of 165 of 262 WATCH participants completed telephone surveys (63%); 81 were undecided about whether antibiotics should always be used for treating acute otitis media. Open-ended responses indicated that antibiotic use should be determined by clinical need, support for general practitioners\' decisions, and the view that some general practitioners prescribed antibiotics too often.
Parents and carers are key partners in managing acute otitis media in urban Aboriginal and Torres Strait Islander children. Our findings support shared decision making informed by the experience of parents and carers, which could also lead to reduced antibiotic use for managing acute otitis media.

OBJECTIVE: The study aimed to explore the impact of middle ear disease on the lives of New Zealand Māori. Ear disease is common, yet there is a paucity of research into the effect it has on people\'s lives, particularly indigenous populations.
METHODS: The study used Kaupapa Māori-based qualitative methodology and involved a series of seven semi-structured interviews with Māori adults living with middle ear disease.
RESULTS: All participants felt there were delays in recognition and treatment of their ear condition and that there were barriers to accessing healthcare. The ear condition prevented participation in cultural and recreational activities, particularly those involving water. The associated hearing loss affected education and employment opportunities, and together with ear discharge, resulted in social isolation and disconnection from Te Ao Māori (the Māori world). Overall, the condition impacted negatively on mental and spiritual wellbeing. Participants felt that funding for hearing aids, earlier recognition and treatment of the condition and healthcare staff with a better understanding of Te Ao Māori could reduce the morbidity associated with middle ear disease.
CONCLUSIONS: The study demonstrates that living with middle ear disease presents many challenges and disadvantages for Māori and the importance of early detection and referral to specialist care.

BACKGROUND: One third of children require repeat ventilation tube insertion (VTI) for otitis media. Disease recurrence is associated with persistent middle ear bacterial biofilms. With demonstration that Dornase alfa (a DNase) disrupts middle ear effusion biofilms ex vivo, we identified potential for this as an anti-biofilm therapy to prevent repeat VTI. First, safety and tolerability needed to be measured.
METHODS: This was a phase 1B double-blinded randomized control trial conducted in Western Australia. Children between 6 months and 5 years undergoing VTI for bilateral middle ear effusion were recruited between 2012 and 2014 and followed for two years. Children\'s ears were randomized to receive either Dornase alfa (1 mg/mL) or 0.9 % sodium chloride (placebo) at time of surgery. Children were followed up at 2 weeks post-VTI and at 3-monthly intervals for 2 years. Outcomes assessed were: 1) safety and tolerability, 2) otorrhoea frequency, 3) blocked or extruded ventilation tube (VT) frequency, 4) time to blockage or extrusion, 5) time to infection recurrence and/or need for repeat VTI.
RESULTS: Sixty children (mean age 2.3 years) were enrolled with 87 % reaching study endpoint. Treatment did not change otorrhoea frequency. Hearing improved in all children following VTI, with no indication of ototoxicity. Dornase alfa had some effect on increasing time until VT extrusion (p = 0.099); and blockage and/or extrusion (p = 0.122). Frequency of recurrence and time until recurrence were similar. Fourteen children required repeat VTI within the follow-up period.
CONCLUSIONS: A single application of Dornase alfa into the middle ear at time of VTI was safe, non-ototoxic, and well-tolerated.

BACKGROUND: Patulous Eustachian tube (PET) is a condition affecting approximately 0.3% to 6.6% of the population, with autophony being the predominant complain. The management of PET lacks a well-defined standard in the literature as no effective medical treatments have been documented but various surgical options are available. This study aims to report mid-term outcomes following surgical management of PET.
METHODS: All patients who underwent surgical intervention for PET between September 2017 and June 2022 were enrolled. Data encompassing general demographics, quality of life (GBI), and procedure-specific data were collected.
RESULTS: A total of 30 PET cases (in 19 patients) underwent surgical intervention including 9 injections of hyaluronic acid, 13 fat injections, 6 endoscopic shim insertions, 1 cartilage graft, and 1 injection of hydroxy apatite. After an average follow-up of 22 ± 14 months, 16 cases (53%) achieved complete symptom relief, while 8 cases (26.6%) reported partial relief. Additionally, 11(36%) cases required multiple surgeries. No specific surgical technique demonstrated superiority. Quality of life improved in 77% of cases based on 10 out of 13 GBI collected. Recurrence of PET symptoms occurred on average 10.6 ± 9.7 months after initial surgery, with an estimated global risk of 75% at 3 years. Transient serous otitis media was observed in only 4 cases (13.3%).
CONCLUSIONS: Surgical intervention for PET was found to be effective, achieving complete symptom relief in 53% of cases and significantly improving quality of life 2 years post-surgery. However, a substantial portion of cases necessitated one or more re-interventions. The durability of effectiveness appears to diminish over time.

Introduction  Tympanoplasty is the main treatment of mucosal type of chronic suppurative otitis media. Objective  The aim of the present study was to compare clinical outcomes in terms of healing and audiological outcomes of two groups. The authors used single layer graft (perichondrium with cartilage island) graft in one group and double layer grafts (perichondrium cartilage island composite plus temporalis fascia) were used in the second group. Methods  Forty patients complained of chronic suppurative otitis media safe type with subtotal perforation subdivided into two groups. The first group author used single-layer perichondrium with cartilage island graft (composite graft) while in the second group authors used double graft in the form of perichondrium/cartilage island (composite graft) plus temporalis fascia. Results  There was no significant difference in the mean Air bone gap (ABG) between pre- and post-operative audiometry in subjects who had single layer tympanoplasty. There was a significant difference in the mean ABG between pre- and postoperative audiometry in subjects who had double layer tympanoplasty. There was a significant difference in in the mean ABG differences between subjects who had single layer tympanoplasty and double layer tympanoplasty. Also, there was a significant difference in the healing of the tympanic membrane between subjects who had single layer tympanoplasty and double layer tympanoplasty. Conclusion  Tympanoplasty by double graft (temporalis fascia and tragal cartilage/perichondrium) achieved a considerable improvement in healing of the tympanic membrane ™ with lower risk for residual perforation or graft rejection.

OBJECTIVE: This study retrospectively evaluated the efficacy and versatility of reopening procedures for the permanent occlusion of the cartilaginous Eustachian tube (POET) by analyzing four consecutive cases.
METHODS: The study included all patients diagnosed with POET who suffered from Eustachian tube occlusion and glue ear. A combined approach of endoscopic transnasal/transoral laser surgery was utilized to reopen the POET. This was subsequently followed by balloon dilation (BET) and stenting for a duration of six weeks. In one distinct case, the Eustachian tube orifice was approached via a transtympanic method, where a balloon catheter was placed. The primary outcome measures targeted the success rate of reopening, which was quantified using audiological outcomes and Eustachian tube patency verified by a positive Valsalva maneuver.
RESULTS: Four patients, with an age range of 14-62 years (mean age of 29.3 years), were subject to Eustachian tube reopening. The duration of follow-up varied between 10 and 24 months, averaging at 16.2 months. Notably, 75% of the surgically treated ears displayed no evidence of glue ear upon their last follow-up and showed restoration of Eustachian tube patency. The procedures were executed without any surgical complications. The causes for POET in these patients were heterogeneous: two were attributed to scarring post adenoidectomy, one to occlusion following orthognathic surgery and the remaining one due to prior radiotherapy treatment for squamous cell carcinoma located at the soft palate.
CONCLUSIONS: Total occlusion of the cartilaginous Eustachian tube may be linked to persistent middle ear diseases. It is imperative to conduct nasopharyngeal endoscopy in these cases. The findings from this study suggest that the Eustachian tube reopening procedure is predominantly effective and safe for patients with POET stemming from a variety of pathologies. Future research should focus on exploring advanced stenting devices and necessitate longer follow-up periods for comprehensive understanding.
