Perilymph fistulas in children: experience of the Otologic Medical Group
Insights
Fistula exploration for hearing loss is rarely successful in children, with most showing no improvement. Exploration is only recommended for progressive hearing loss with inner ear deformities to rule out perilymph fistulas.
Area of Science:
- Otolaryngology
- Neurosurgery
- Audiology
Background:
- Perilymph fistulas can cause sudden sensorineural hearing loss (SNHL), dizziness, and meningitis.
- Previous approaches involved routine exploration for SNHL, but success rates varied widely.
- The Otologic Medical Group (OMG) shifted towards selective exploration criteria.
Purpose of the Study:
- To evaluate the outcomes of surgical exploration for suspected perilymph fistulas in pediatric and adult patients.
- To determine the efficacy of fistula exploration in cases presenting with hearing loss and dizziness.
Main Methods:
- Retrospective review of 86 consecutive fistula explorations over 12 years.
- Analysis of patient demographics, presenting symptoms, surgical findings, and postoperative outcomes.
- Specific focus on nine pediatric patients undergoing fistula exploration.
Main Results:
- None of the nine pediatric patients had a confirmed fistula.
- Postoperative hearing outcomes in children included one improvement, five no changes, and two worsening.
- In adults, 35 fistulas were identified; outcomes varied, leading to selective exploration criteria.
Conclusions:
- Fistula exploration should be considered for progressive or fluctuating sensorineural hearing loss, particularly with congenital inner ear deformities.
- Surgical exploration for suspected perilymph fistulas in children is generally not recommended unless specific criteria are met.
- Hesitancy in exploring patients for fistulas is advised due to variable success rates and the low incidence of confirmed cases.
Abstract:
We reviewed records of 86 consecutive fistula explorations over 12 years. Four cases were children under age 18. There were 35 fistulas, all in adults. Since this series, we have identified five more children with fistula explorations for a total of nine patients. Two had bilateral explorations. Presenting symptoms were hearing loss and dizziness. None of the children had a definite fistula. Of the nine patients, one patient had a significant improvement in hearing postoperatively, five had no change, and two had worse hearing. There was no follow-up in two patients or in the second ear of a bilateral case. We feel that a fistula should be considered in any case of progressive or fluctuating sensorineural hearing loss, especially in cases with a congenital inner ear deformity. In such cases, an exploration may be reasonable to rule out a fistula. Otherwise, we are hesitant to explore patients for fistulas regardless of whether they are children or adults. Sudden, progressive, and fluctuating sensorineural hearing loss, dizziness, and meningitis have been attributed to perilymph fistulas in both adults and children. The literature reports fistulas in all types of conditions. The incidence and degree of success of treatment have varied widely. When Goodhill first reported round window rupture as a cause of sudden sensorineural hearing loss (SNHL), the Otologic Medical Group (OMG) began routine exploration of all cases of sudden SNHL for the presence of fistulas. After 50 consecutive cases were explored and no fistulas were found, we became selective in our exploration candidates.(ABSTRACT TRUNCATED AT 250 WORDS)
