Frenulumoscopy is a medical procedure that involves the examination of the frenulum, which is the small fold of tissue that secures the movement of an organ in the body, such as the tongue or the genitals. This procedure is often used to assess conditions related to frenulum abnormalities, such as tongue-tie or other issues affecting oral or genital function. It may be performed using a specialized endoscope to provide a clear view of the frenulum and surrounding tissues.
