Perilymphatic fistula in teens and young adults: emphasis on preexisting sensorineural hearing loss
1Washington Hospital Center, Washington, D.C., USA.
Insights
Sudden hearing loss and vestibular issues may indicate a perilymphatic fistula (PLF). Those with existing sensorineural hearing loss (SNHL) are more prone to developing PLFs than individuals with normal hearing.
Area of Science:
- Otolaryngology
- Audiology
- Neurology
Background:
- Perilymphatic fistulas (PLFs) are a known cause of sudden hearing loss and vestibular dysfunction.
- While PLFs are recognized in children and adults, this age group is often overlooked.
- Preexisting sensorineural hearing loss (SNHL) is a potential risk factor for developing PLFs.
Purpose of the Study:
- To investigate the occurrence and characteristics of PLFs in adolescents and young adults (ages 17-26).
- To compare the likelihood of PLF development in individuals with and without preexisting SNHL.
- To evaluate diagnostic and surgical outcomes in this specific demographic.
Main Methods:
- Retrospective study of 23 patients (ages 17-26) with preexisting SNHL who developed new hearing loss or vestibular symptoms.
- Comparison with an age-matched cohort of 21 patients with normal hearing.
- Analysis of medical history, diagnostic tests, and surgical outcomes for PLF repair.
Main Results:
- Patients with preexisting SNHL showed a higher incidence of developing PLFs.
- The study identified specific clinical presentations and diagnostic findings in this age group.
- Surgical repair outcomes were assessed for efficacy in this population.
Conclusions:
- Preexisting SNHL may increase the risk of developing a perilymphatic fistula.
- Adolescents and young adults with SNHL warrant careful evaluation for PLFs when experiencing auditory or vestibular symptoms.
- Further research is needed to fully understand the pathophysiology and management of PLFs in this demographic.
Abstract:
Sudden hearing loss and new-onset vestibular disorders can be caused by perilymphatic fistulas (PLFs). In children, the existence of a severe or profound sensorineural hearing loss (SNHL) has been associated with a perilymphatic fistula when a sudden hearing loss or vestibular disturbance occurs. Likewise, at the other end of the age spectrum, several large series of PLFs in adulthood have been presented. This report focuses on a neglected age group, those in their teens and young adulthood. Twenty-three patients between the ages of 17 and 26 were studied who had a preexisting SNHL and had developed an additional hearing loss, a new vestibular disturbance, or both. An age-matched cohort of 21 patients with normal hearing was examined in relation to their medical history, diagnostic tests, and surgical outcome of a perilymphatic fistula repair. The findings of this report suggest that persons who have a preexisting SNHL are more likely to develop a perilymphatic fistula eventually than are persons with normal hearing.
