someone asked me in a message if I could share Dr Ousterhout's description of Type I. Below is a quote from his book.
In his book, "Facial Feminization Surgery, A Guide for the Transgendered Woman", Douglas K. Ousterhout, MD says
"Type I
Individuals who undergo a Type I procedure usually don't have as severe an issue with their foreheads as other MTF patients. (See Figure 4-4) Only 9 percent of my MTF forehead patients, eighty-five individuals, have needed this type of forehead correction. It is designed for those who had no frontal sinuses (fifty-three of the eighty-five) or had a very small frontal sinus and/or a very thick anterior frontal sinus wall (thirty-two of the eighty-five). A Type I approach consists of burring away the excess forehead bone and developing a desired female contour without entering the frontal sinus, if it exists. (See Figures 4-3a,4-3b.) Although it is the easiest of my four forehead approaches, it must be accomplished in such a way that the bone is not burred down so thin that the underlying frontal sinus, if there is one, is vulnerable to trauma to injury." (39-40).
