Key Points

  • Investigate the significance of fetal tympanic ring anomalies as potential indicators of severe monogenic disorders.
  • Performed ultrasound evaluations during the second trimester
  • Identified tympanic ring anomalies and minor ultrasound markers
  • Analyzed the need for genetic assessments based on findings
  • Fetal tympanic ring anomalies were found to indicate a need for genetic assessment
  • These anomalies often occurred with minor markers
  • More studies are recommended to integrate findings into clinical guidelines

Abstract

Ultrasound evaluation of fetal tympanic ring abnormalities is feasible during the second trimester. Fetal tympanic ring anomalies even occurring with minor ultrasound markers may represent a significant indication for a comprehensive genetic assessment. More studies are needed to establish how tympanic ring anomalies should be integrated into routine clinical practice.
