Would Roaccutane help (don't have a copy of MIMs handy)?

There is certainly a muscular attachment to the Eustachian Tube (in fact
several); I had to look it up, as although I did a prosection of that area
to demonstrate the attachment (there should be a pot of it in the anatomy
museum of USyd), I can't recall the name. According to Gray's Anatomy, it's
the dialator tubae, but I thought it looked more like some fibres from the
lateral pterygoid. Most methods of opening the tune involves using the
levator veli palati to stretch the tube, and thus open it.
