Background Sagging of the neck aesthetic area is an important indicator of age. The development of complex and globally accepted tools for proper assessment of the change in neck volume is an essential contribution to aesthetic research and the routine clinical setting.

Objective To develop a grading scale for the objective assessment of the neck volume and to establish the reliability of this scale for clinical research and practice.

Materials and Methods A 5-point rating scale was developed to assess neck volume objectively. Twelve experts rated frontal and lateral neck photographs of 50 subjects in two separate rating cycles using the neck volume scale. Responses of raters were analyzed to assess inter- and intrarater reliability.

Results Interrater reliability for the neck volume scale was almost perfect, with intraclass correlation coefficients for the first and second rating cycles of 0.85 and 0.84, respectively. Intrarater reliability for the neck volume scale was high (0.90) and Pearson correlation coefficients ranged between 0.88 and 0.95 and were statistically significant.

Conclusion The neck volume scale demonstrates optimal reliability for clinical research and practice.
