The Schnur scale is a standardized visual assessment tool used to grade the severity of gynecomastia, a condition characterized by enlarged breast tissue in males. The assessment involves comparing the patient’s chest contour to a series of photographic standards that represent different degrees of glandular tissue and skin excess. The classification ranges from Grade I, indicating minor breast enlargement without skin excess, to Grade III, which denotes marked breast enlargement with significant skin redundancy resembling female breasts. The system may further be subdivided into categories based on the presence or absence of ptosis (nipple drooping) to refine the grading process. The determination of the grade relies on visual comparison, often assisted by palpation to assess tissue volume and skin laxity.
This classification system provides several benefits. It allows for consistent communication among healthcare professionals regarding the extent of gynecomastia. Furthermore, it assists in determining the appropriate surgical approach, guiding decisions regarding liposuction, glandular excision, and skin resection. Its use also aids in tracking treatment progress and documenting outcomes. Originally proposed as a descriptive system, it has become a widely adopted standard in clinical practice and research involving gynecomastia.
