Timing of symptom resolution was evaluated and compared to the results of a questionnaire sent to all parents in June 1996. Results: Most patients were asymptomatic or improved by 3 months postoperatively, and the long-term success rate was 96.6%. Conclusion: Optimum timing of follow-up should be 3 months postoperatively, if necessary at all.
