Ear and hearing care programs for First Nations children: a scoping review

BACKGROUND

Ear and hearing care programs are critical to early detection and management of otitis media (or middle ear disease). Otitis media and associated hearing loss disproportionately impacts First Nations children. This affects speech and language development, social and cognitive development and, in turn, education and life outcomes. This scoping review aimed to better understand how ear and hearing care programs for First Nations children in high-income colonial-settler countries aimed to reduce the burden of otitis media and increase equitable access to care. Specifically, the review aimed to chart program strategies, map the focus of each program against 4 parts of a care pathway (prevention, detection, diagnosis/management, rehabilitation), and to identify the factors that indicated the longer-term sustainability and success of programs.

METHOD

A database search was conducted in March 2021 using Medline, Embase, Global Health, APA PsycInfo, CINAHL, Web of Science Core Collection, Scopus, and Academic Search Premier. Programs were eligible or inclusion if they had either been developed or run at any time between January 2010 to March 2021. Search terms encompassed terms such as First Nations children, ear and hearing care, and health programs, initiatives, campaigns, and services.

RESULTS

Twenty-seven articles met the criteria to be included in the review and described a total of twenty-one ear and hearing care programs. Programs employed strategies to: (i) connect patients to specialist services, (ii) improve cultural safety of services, and (iii) increase access to ear and hearing care services. However, program evaluation measures were limited to outputs or the evaluation of service-level outcome, rather than patient-based outcomes. Factors which contributed to program sustainability included funding and community involvement although these were limited in many cases.

CONCLUSION

The result of this study highlighted that programs primarily operate at two points along the care pathway-detection and diagnosis/management, presumably where the greatest need lies. Targeted strategies were used to address these, some which were limited in their approach. The success of many programs are evaluated as outputs, and many programs rely on funding sources which can potentially limit longer-term sustainability. Finally, the involvement of First Nations people and communities typically only occurred during implementation rather than across the development of the program. Future programs should be embedded within a connected system of care and tied to existing policies and funding streams to ensure long term viability. Programs should be governed and evaluated by First Nations communities to further ensure programs are sustainable and are designed to meet community needs.

Congenital cholesteatoma in identical twins

Congenital cholesteatoma in identical twins has only been described once in Otolaryngology literature thus far^. This report describes a case of monozygotic twins with a history of recurrent acute otitis media and bilateral middle ear effusions without tympanic membrane perforation. Upon myringotomy with pressure equalization tube insertion, both were found to have right-sided cholesteatoma with nearly identical location and pattern of progression. In the context of previous case series demonstrating familial clustering and reports of possible genetic associations of this condition, the authors present an important addition to the current understanding of congenital cholesteatoma disorder.

Endoscopic Stapes Surgery: Pearls and Pitfalls

The endoscopic approach to stapes surgery affords unique advantages but is not without its specific challenges. The following reviews the equipment and surgical steps required to perform endoscopic stapes surgery safely and effectively, highlighting tips and potential points of failure through a series of case examples.

Middle ear disease in CF? It's not just about the sinuses anymore!

INTRODUCTION

Historically cystic fibrosis (CF), in contrast to primary ciliary dyskinesia (PCD), has been considered protective of the middle ear from otitis media and rarely were such patients "severely affected" to require tympanostomy tube placement (BMT). Previously the Pittsburgh Otitis Media Research group reported a 10% prevalence of otitis media in the pediatric CF population which is significantly lower than age matched non-CF children. We studied the prevalence of OM in pediatric CF patients to assess if the otologic phenotype has changed in parallel with changes in the diagnosis itself.

METHODS

The medical records of 133 CF patients seen either inpatient or outpatient from one of the largest tertiary pediatric CF centers in the world from 2010 to 2019 were reviewed for demographics, acute otitis media (AOM) episodes, risk factors for AOM, placement of myringotomy tubes, genotype, BMI, pancreatic status, respiratory culture results, and pulmonary exacerbations.

RESULTS

Just over half (52.6%) the patients were male. A median age for CF diagnosis was 11 days old (range 0 days-16 years). The most common genotype (49.6%) was homozygous for ΔF508 mutation. Fifty-five (41.4%) patients had 1-2 episodes of AOM, and 15 (11.3%) were severely affected (i.e. ≥3 episodes/6 months or ≥4 episodes/year). COME was diagnosed in 4 (3.0%) of the patients. Twelve (9.0%) patients had tympanostomy tubes at least once, including 3 patients with multiple sets of tubes. Having at least one AOM episode was not predicted by genetic mutation groups, BMI, age at diagnosis, or comorbidities, p > .05.

CONCLUSIONS

The time-honored adage of CF protecting against otitis media is no longer true and pediatric otolaryngologists must now prioritize the management of middle ear disease as highly as sino-nasal and pulmonary disease. Future study into mechanisms explaining the change is needed.

What Role Does Allergy Play in Chronic Ear Disease and Laryngitis?

IgE-mediated allergy plays a well-established role in both nasal and pulmonary diseases due to the common epithelium and shared mediator responses of the upper and lower airways. This "unified airway" concept has also been described in other sites within the head and neck that contain similar respiratory mucosa: the middle ear and the larynx. This review will highlight the data suggesting a role for IgE-mediated allergic disease in chronic laryngopharyngeal and middle ear disease and the role for allergy testing to aid in diagnosis and treatment of these disorders.

Finite element analysis of auditory characteristics in patients with middle ear diseases

CONCLUSION

This study validates that a finite element model of the human ossicular chain and tympanic membrane can be used as an effective surgical assessment tool in clinics.

OBJECTIVE

The present study was performed to investigate the application of a finite element model of ossicular chain and tympanic membrane for fabrication of individualized artificial ossicles.

METHODS

Twenty patients (20 ears) who underwent surgery for middle ear disease (n = 20) and 10 healthy controls (10 ears) were enrolled in the hospital. Computed tomography (CT) and pure tone audiometry were performed before and after surgery. A finite element model was developed using CT scans, and correlation analysis was conducted between stapes displacement and surgical methods. An audiometric test was also performed for 14 patients before and after surgery.

RESULTS

Stapes displacement in the healthy group (average = 3.31 × 10^-5 mm) was significantly greater than that in the impaired group (average = 1.41 × 10^-6 mm) prior to surgery. After surgery, the average displacement in the impaired group was 2.55 × 10^-6 mm, which represented a significant improvement. For the patients who underwent the audiometric test, 10 improved hearing after surgery, and stapes displacement increased in nine of these 10 patients.

A 3-D analysis of the protympanum in human temporal bones with chronic ear disease

Eustachian tube dysfunction is believed to be an important factor to cholesteatoma development and recurrence of disease after surgical treatment. Although many studies have described prognostic factors, evaluation methods, or surgical techniques for Eustachian tube dysfunction, they relied on the soft tissues of its structure; little is known about its bony structure-the protympanum-which connects the Eustachian tube to the tympanic cavity, and can also be affected by several inflammatory conditions, both from the middle ear or from the nasopharynx. We studied temporal bones from patients with cholesteatoma, chronic otitis media (with and without retraction pockets), purulent otitis media, and non-diseased ears, looking for differences between the volume of the protympanum, the diameter of the Eustachian tube isthmus, and the distance between the anterior tympanic annulus and the promontory. Light microscopy and 3-D reconstruction software were used for the measurements. We observed a decrease of volume in the lumen of the four middle ear diseased ears compared to the control group. We observed a significant decrease in the volume of the protympanic space in the cholesteatoma group compared to the chronic otitis media group. We also observed a decrease in the bony space (protympanum space) in cholesteatoma, chronic otitis media with retraction pockets, and purulent otitis media compared to the control group. We found a correlation in middle ear diseases and a decrease in the middle ear space. Our findings may suggest that a smaller bony volume in the protympanic area may trigger middle ear dysventilation problems.

Cholesteatoma has a high prevalence in Turner syndrome, highlighting the need for earlier diagnosis and the potential benefits of otoscopy training for paediatricians

AIM

Girls with Turner syndrome are prone to cholesteatoma, a serious suppurative middle ear disease. We aimed to confirm its high prevalence in Turner syndrome, identify risk factors and suggest possible strategies for earlier detection.

METHODS

We reviewed 179 girls with Turner syndrome between 1989 and 2012 to identify cases of cholesteatoma.

RESULTS

Seven girls (3.9%) had cholesteatoma (index girls) and each was compared with three age-matched girls without cholesteatoma (comparison girls). All the index girls had either the 45,X or 45,X/46X,i(Xq) karyotypes. Nine ears were initially affected, with three recurrences in two girls. Median age at first cholesteatoma presentation was 11.9 years (range: 7.5-15.2), with otorrhoea for three (range: one to seven) months in all 12 affected ears. Index girls had a significantly higher proportion of previous recurrent acute (p = 0.007) and chronic otitis media (p = 0.008), chronic perforation (p = 0.038) aural polyps (p < 0.0001) and tympanic membrane retraction (p = 0.0001) than comparison girls.

CONCLUSION

Cholesteatoma has a high prevalence in Turner syndrome. Risk factors include 45,X and 46,XiXq karyotypes; a history of chronic otitis media, tympanic membrane retraction and persistent otorrhoea; and older age. Earlier recognition of ear disease is needed and otoscopy training for paediatricians caring for Turner syndrome patients may be beneficial.
