What is labial hypertrophy? When the distance between the center point of the base of labia minora and the lateral edge of labia minora is greater than 4cm, it is called labia minora hypertrophy. The shape of the enlarged labia minora varies, and most of them resemble the ears of a dog with long ears or pig ears. Labia minora hypertrophy can be symmetrical or asymmetrical (different sizes on both sides). It can be congenital or acquired. Most of the acquired labia minora hypertrophy is due to long-term local chronic stimulation or continuous friction, such as female vaginitis, vulvovaginitis, due to long-term stimulation of inflammatory secretions, resulting in chronic hypertrophy of labia minora skin and mucous membrane, local skin and mucous membrane roughness and increased pigmentation. Some long-term bicycle or motorcycle workers can also cause labia minora hypertrophy due to long-term friction and extrusion. The enlarged labia minora is not only unsightly in appearance, but also causes psychological barriers to some patients, and brings many inconveniences to patients’ lives. For example, the enlarged labia minora feel discomfort due to local squeezing and friction when exercising, walking, cycling or sitting for a long time. Or it is painful during menstruation due to the friction of sanitary napkin, some patients experience blockage or painful discomfort during sexual intercourse, and some patients can develop local ulcers and suffer. Therefore, the enlarged labia minora should be treated surgically when it affects normal life. However, for some reasons, most patients are too shy to seek medical attention, thinking that it is a disease that cannot be seen and suffer in silence, which is a very wrong idea. After labia minora enlargement surgery, the newly formed labia minora will be natural in color, moderate in size, beautiful in appearance, and no local scar will be left behind. More importantly, the patient can regain self-confidence.
