Bruce Jenner is no greenhorn when it comes to plastic surgery, but he only showed off his latest procedure during filming for Keeping Up With The Kardashians last Monday, February 10th. The 64-year-old reality star stepped out in Thousand Oaks, California for the shoot, sporting an open neck blue T-shirt and newly puffed up bouffant hair.

Perhaps the Kardashians' stepdad just wanted to avoid the stigma associated with extreme cosmetic surgery.

This is the first time Jenner has been photographed since he recently underwent a procedure at Beverly Hills Surgical Center to flatten his Adam's apple. According to an anonymous source for Us Weekly, the surgery was originally scheduled for December, but was later postponed for January 19, after Jenner’s plans were leaked.

This could be due to Jenner’s reluctance to have his procedure publicized. Again according to Us, this particular procedure can often be one step in the process of a gender transition. Of course, that does not mean that Jenner is going through the transition himself, he might have just wanted to avoid the rumor.

The laryngeal shave (which starts at $5,000) "is, in many cases, a part of gender-reassignment surgeries," explains NYC-based cosmetic surgeon Michael Jones. "But that's not the only reason to have it."

The former Olympian, however, maintains that this was not his reason for having the procedure – he just wanted to fix a cosmetic defect. “I just didn't like my trachea.”

Jenner says he had the surgery purely for aesthetic reasons - he just didn't like his trachea.
