Type 1 forehead reduction describes a specific technique to reduce brow bossing (brow protrusion). This type of procedure is commonly performed for transgender women, however it is also done for cisgender women and cisgender men who are dissatisfied with the appearance of their forehead.
The term “type 1” comes from research performed by Dr. Douglas Ousterhout. In his research, he noticed there were three types of foreheads he encountered when performing modifications of frontal bossing. A type 1 forehead is one where the brow bossing can be addressed with burring alone. A type 2 forehead is one where the brow bossing was addressed by burring the bone low on the forehead and augmenting the upper forehead using artificial material to improve the transition. A type 3 forehead is one where the brow bossing needs to be addressed by making cuts in the forehead bone and repositioning that bone.
Contouring the forehead can occasionally involve only burring of the bone in that region (type 1 forehead reduction). Contouring alone is only possible when a patient’s anatomy is appropriate for that procedure. If the frontal sinuses are large, then burring the forehead bone would either produce an inadequate setback or result in the creation of a large hole into the frontal sinus before an appropriate degree of forehead setback is reached. The presence and size of frontal sinuses are commonly evaluated preoperatively using x-ray imaging or a CT scan.
The illustrations below demonstrate a type 1 forehead reduction on a type 1 forehead. This type of forehead reduction requires that the frontal sinus be small or located behind the desired setback location. With a frontal bone (forehead bone) of this anatomy, one can simply bur the bone in this region to obtain the desired degree of setback.
How much does a type 1 forehead reduction cost?
The cost of a type 1 cranioplasty depends on a few factors. The primary factor is whether insurance will cover the procedure. It may also vary depending on whether additional procedures are being performed during the same operation. There are also variations between surgeons.

How is the recovery after a type 1 forehead reduction?
Recovery from a type 1 cranioplasty is relatively easy. There will be an incision in the scalp, which is performed to provide surgical access to the forehead bone. There will be swelling of the forehead that will significantly reduce over the first few weeks but may take a few months to reach its final state.
How painful is the recovery?
This portion of a facial feminization operation produces relatively little pain. There will be swelling around the eyes, which produces discomfort, and there will be some degree of a headache. Pain is easily managed with oral pain medications.
How much time do I need off work after a type 1 forehead reduction?
Taking at least one week off work is ideal. This allows the swelling to subside and for the incisions to become less noticeable. Depending on the extent of surgery and the desire for privacy, some people opt to take a few weeks off work to allow the incisions to heal more completely and for the swelling to subside more significantly.
What are the risks of a type 1 cranioplasty?
A type 1 cranioplasty is safer than a type 3 cranioplasty. It is less likely to result in contour irregularities and there are fewer concerns about instability of the frontal bone. As with any forehead reduction technique, there is a chance of nerve damage to the nerves that move the forehead and eyebrows and the nerves that supply sensation to the forehead. There is a possibility of having asymmetries and contour irregularities.
It is uncommon that someone will be a candidate for a type 1 cranioplasty since it requires the presence of very small frontal sinuses. More commonly, one’s individual anatomy will require performing a type 3 cranioplasty (cutting and moving the brow bone).
How long will the results last from a type 1 forehead reduction?
This is a permanent procedure. The bone does not grow back in this region to an extent that would produce brow bossing later in life.
What can be done if a type 1 forehead reduction was performed and there is inadequate reduction of brow bossing?
Some patients with a type 3 forehead undergo a type 1 cranioplasty. In these scenarios, they may have an inadequate reduction of their frontal bossing or holes into their frontal sinuses. A surgical revision is required in these cases in order to correct the issue. This may require performing a type 3 cranioplasty.
Who is a candidate for a type 1 forehead reduction?
It is important to discuss facial feminization surgery with your surgeon to determine your candidacy. It is uncommon for a type 1 cranioplasty to provide a sufficient amount of setback for most patients. Most patients have a large frontal sinus that prevents sufficient setback with burring alone.
A consultation with us commonly includes a CT scan of the facial bones to determine which type of forehead setback is best for you.
