Summary
This study developed an objective submental fat rating scale for Koreans using validated CR-SMFRS and reference photos. The tool demonstrated high inter-rater reliability, ensuring consistent assessment of submental fat in the Korean population.
Area of Science:
- Plastic Surgery
- Dermatology
- Medical Imaging
Background:
- Submental fat assessment requires objective tools.
- Existing scales may not be universally applicable, especially to specific ethnicities like Koreans.
Purpose of the Study:
- To develop and validate an objective tool for rating submental fat.
- To create a culturally relevant submental fat rating scale for Korean subjects.
Main Methods:
- A total of 92 subjects were enrolled in the study.
- Clinical photos were categorized using the validated CR-SMFRS (Clinician-Rated Submental Fat Rating Scale).
- Six plastic surgeons evaluated the categorized photos, assessing inter-rater reliability.
Main Results:
- High inter-rater reliability was achieved, with Cohen's kappa values ranging from 0.703 to 0.907 (p < 0.001).
- Intraclass Correlation Coefficient (ICC) values were between 0.860 and 0.966 (p < 0.001), indicating excellent agreement.
- All raters demonstrated reliability above the 0.6 threshold, validating their inclusion in the analysis.
Conclusions:
- A set of reference photos was developed for a submental fat rating scale.
- This scale is applicable and validated for Korean subjects.
- The developed tool provides an objective and reliable method for assessing submental fat in the target population.
