Grade is a term used to classify how severe your inverted nipples are. Your surgeon will assess your nipples and use the grading system to determine the best course of treatment.
Grade 1 – The mildest form of inverted nipples. The nipples will have a flat appearance but often still respond to touch or temperature changes and become everted for a short amount of time.
Grade 2 – A mild grade of inverted nipples that have a more inverted appearance. Grade 2 inverted nipples will often still become everted when stimulated however they will usually immediately return to their inverted position.
Grade 3 – The most severe grade of inverted nipples. Grade 3 inverted nipples will often not evert at all and remain in an inverted position at all times.
