Abstract

Background:
Accurate assessment of thyroid gland size is essential for diagnosing and managing thyroid disorders. While ultrasonography is a non-invasive and cost-effective method for evaluating thyroid volume, no reference values currently exist for the adult Cambodian population.

Objective:
This study aimed to determine normative ultrasound-based thyroid volume values in euthyroid Cambodian adults, hypothesizing that thyroid volume varies significantly by sex and lobe side.

Materials and Methods:

A prospective cross-sectional study was conducted on 513 adults (306 females, 207 males) aged 18–78 years at the xxxx between April and November 2020. Inclusion criteria included normal thyroid parenchyma and absence of nodules on ultrasound. Volumes of both lobes were calculated using the ellipsoid formula: Height × Width × Thickness × π/6. Data were analyzed using Excel and SPSS version 26, with significance set at p<0.05.

Results:
The mean thyroid volume was 7.51 ± 2.74 mL. Males had significantly larger thyroid volumes (8.05 ± 2.87 mL) than females (7.15 ± 2.60 mL) (p<0.05). The right lobe (4.27 ± 1.55 mL) was significantly larger than the left lobe (3.24 ± 1.33 mL) in both sexes (p<0.05).

Conclusion:
This is the first study to establish ultrasound-based reference values for thyroid volume in Cambodian adults. The findings confirm that thyroid volume is greater in males than females and that the right lobe is typically larger than the left. These values provide a valuable baseline for clinical assessment and future research in Cambodia.
