  • Title: Perilymph fistulas in children: experience of the Otologic Medical Group.
    Author: House JW, Rizer FM.
    Journal: Am J Otol; 1989 Nov; 10(6):493-5. PubMed ID: 2610242.
    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)
