Insights
Hearing loss affects nearly 11% of children with septo-optic dysplasia (SOD). Sensorineural hearing loss is most common, with early detection and treatment crucial for managing this condition in pediatric patients.
Area of Science:
- Pediatric Otolaryngology
- Neuro-ophthalmology
- Genetics and Rare Diseases
Background:
- Septo-optic dysplasia (SOD) is a congenital disorder characterized by the triad of optic nerve hypoplasia, pituitary abnormalities, and midline brain defects.
- Hearing impairment is a potential, yet often under-recognized, comorbidity in children diagnosed with SOD.
Purpose of the Study:
- To determine the prevalence and characteristics of hearing loss (HL) in a pediatric cohort with septo-optic dysplasia (SOD).
- To identify the types of hearing loss and associated otologic conditions in children with SOD.
Main Methods:
- Retrospective review of otologic and audiometric data for pediatric patients (<18 years) with SOD.
- Data collected from a specialized pediatric hospital clinic (2013-2017) and supplemented by a Medline literature search.
Main Results:
- Seven out of 64 (10.9%) pediatric SOD patients were diagnosed with hearing loss.
- Sensorineural hearing loss (SNHL) was the predominant type (63%), often bilateral.
- Associated findings included cochlear nerve deficiency and atresia/microtia; 57% required tympanostomy tubes.
Conclusions:
- Nearly 11% of children with SOD experience hearing loss, primarily SNHL.
- This study is the first to report on hearing loss in a pediatric SOD cohort, including novel findings of cochlear nerve deficiency and atresia/microtia.
- Early identification of hearing loss via audiological evaluation and imaging, alongside prompt otitis management, is recommended for this population.
Objective:
To identify and characterize hearing loss (HL) in children with septo-optic dysplasia (SOD).
Methods:
Otologic and audiometric data for patients less than 18 years of age identified as having SOD who were seen in the Children's Healthcare of Atlanta-Scottish Rite Hospital clinic between 2013 and 2017 were collected and reviewed through a HIPAA-compliant medical record search. Relevant literature was also reviewed with the assistance of Medline.
Results:
Sixty-four patients with SOD were identified, and 7 of those patients (10.9%) were diagnosed with hearing loss. Type of hearing loss was sensorineural (SNHL) in 5 patients (63%), mixed (MHL) in 1(14%), and conductive (CHL) in 1(14%). Bilateral loss presented in 60% (3/5) of SNHL patients, while the rest demonstrated unilateral loss. Unilateral findings included cochlear nerve deficiency (1) and atresia/microtia (1). Tympanostomy tubes were required in 57% (4/7) of SOD children with hearing loss. Amplification was successfully implemented in 86% (6/7).
Conclusions:
Hearing loss was found in nearly 11% of SOD children, and SNHL was identified as (63%) the predominant form of loss. To our knowledge, this is the first retrospective review of hearing loss in a pediatric SOD cohort and the first to report of cochlear nerve deficiency and atresia/microtia in this population. Based on these findings, early identification of hearing loss with imaging when appropriate and treatment of otitis in this population is recommended.
