Bruce Jenner is flattening his Adam's Apple ... TMZ has learned. Sources familiar with the situation tell TMZ ... the Olympian met with a Beverly Hills plastic surgeon today for a consultation for a procedure called a Laryngeal Shave -- which smooths out the Adam's Apple. The procedure is typically done on patients who are in the first stage of gender reassignment, but Bruce tells TMZ that is NOT the case with him. He says, "I just never liked my trachea." We know this is Bruce's second visit to the office. The doctor took photographs today and sources tell us surgery has been scheduled for early next year, but Bruce insists no surgery has been set yet -- it was just a consultation.
