Reliability of measurements of facial profile parameters by operators with different levels of experience at 15 to 23 weeks of gestatio

Completed

• Conditions: Abnormal development of fetal mandible Micrognathia Retrognathia; fetal facial profile; fetal mandible; inferior facial angle; mandible length; obstetrics; ultrasonography; mandible width

• Registration Number: TCTR20210609003
• Lead Sponsor: Faculty of Medicine Prince of Songkla University

Brief Summary

Intraobserver variabilities of anteroposterior mandibular diameter, mandible width, maxilla width, and mandible length measurements were excellent (ICC 0.958-0.986), while those of inferior facial angle measurements were moderate to excellent (ICC 0.560-0.923). Interobserver variabilities varied between pairs of operators; only two parameters, anteroposterior mandibular diameter and mandible length, showed excellent interobserver variabilities (ICC more than 0.9), with good agreement.
