Choosing the surgical technique you will undergo is one of the most important steps in your top surgery process. The type of technique you choose will determine your sensory and aesthetic outcomes–including scarring, chest contour, as well as nipple placement and dimensions. In a free consultation at the Gender Confirmation Center (GCC) in San Francisco and Prosilio Care in Pasadena, our board-certified surgeons use proven assessment methods to match patients with the best top surgery incision type for their anatomy and goals. Whether you wish to undergo masculinizing or “FTM” top surgery, or have a more non-binary approach, this guide will help you understand how our expert team makes these decisions with patients.
Generally speaking, the type of top surgery that is right for you is determined by your anatomy and your unique goals for surgery. During a free virtual or in-person consultation, our surgeons will assess photos you send us of your chest, alongside your medical history, to determine which techniques will be most likely to help us meet your goals in terms of aesthetics and function.
At the GCC, we do not require that patients undergo hormone replacement surgery (HRT) to be a candidate for surgery. Likewise, most insurance providers do not require patients to be on testosterone HRT to qualify for coverage for gender-affirming top surgery.
Generally speaking, the GCC is one of the few gender-affirming surgical practices that does not discriminate based on body mass index (BMI) to determine top surgery eligibility. That said, patients with a BMI >60 may not receive approval to proceed with surgery from hospital anesthesia departments. This is because of safety concerns and functional limitations around providing adequate air to the lungs during surgery.
Many patients ask how they can figure out what incisions will be available to them. Dr. Scott Mosser (he/him)’s tried and true method for determining which types of top surgery his patients are eligible for involves measuring their inframammary angle. The angle is a great way to measure relevant aspects of your anatomy like skin elasticity, amount of chest tissue, and amount of skin overhang, to help you understand which procedures you qualify for.
You might be able to make these observations without taking a photo of your chest, but if you’d like to analyze a photo of yourself, here are some guidelines:
In order to observe and measure the angle of your lower chest tissue area, you will need to take a photo of your chest following these two guidelines:
The images above show the type and placement of the angle we are looking for. As you can see, that angle below the chest is clearly visible as long as the person being photographed is facing diagonally relative to the camera.
Based on your inframammary angle, you may qualify for the following top surgery incision types:
If your inframammary angle––the angle from your torso to the bottom of your mammary tissue––is greater than 135 degrees, you likely have minimal breast tissue and skin overhang. Also, there’s likely not a lot of “projection” (projection means how far the areola & nipple are positioned out forward from the chest due to them sitting on prominent chest tissue). Projection can lead to hanging skin when all of that volume is gone.
Patients that fit into this category often qualify for a keyhole or periareolar top surgery, depending on the amount of skin that would need to be removed.
Something for patients considering the periareolar approach to be aware of is glandular ptosis, when the nipple and areola sit high on the chest, or when the area beneath the nipple bulges out beneath the nipple/areolar region, as illustrated to the left with shading.
Because the person depicted in the image has an inframammary angle of less than 90 degrees, they would not be eligible for a periareolar procedure, but the image is provided to illustrate glandular ptosis, which can occur in patients with an inframammary angle of greater than 135 degrees as well.
This circumstance can make the final appearance of a periareolar procedure hard to predict, and sometimes unintended results, like bulges on the lower chest, can occur. Even patients without glandular ptosis can encounter issues with this approach, so it is important to weigh the risks and rewards of the periareolar procedure in order to make an informed decision for your own body.
If the angle is about 110 degrees (just a bit wider than a right angle) or more, you are in the middle ground of having too much extra skin for a keyhole incision, but perhaps not so much that a double-incision is necessary. You can consider the following options if you fall into this category:
Many top surgery patients have an inframammary angle of less than 90 degree. Virtually all of these patients require extensive skin removal, and therefore will require either a double-incision approach, an inverted-T approach, or the buttonhole approach.
The inverted T and buttonhole techniques are ideal for patients who would like to maintain some volume to their chest and high nipple sensitivity. Patients that would like a completely flat result, but who also want to maintain high levels of nipple sensitivity, can opt for a double incision nerve reconstruction procedure.
Not all surgeons use the same methods when helping a patient figure out which incision type would be best for them. For example, Dr. Jacobs (he/him) uses a simpler method. It involves a patient lying down pre-op to determine if they would be a good candidate for a top surgery procedure that involved minimally scarring. He describes this method more carefully in the video below.
Please note that thanks to new developments in surgical technology, double incision patients can undergo a nerve reconstruction procedure to maintain heightened sensitivity in their nipples.
Additionally, in the clip below, Dr. Jacobs discusses other aesthetic considerations that come into play with choosing which techniques will help you meet your aesthetic goals for top surgery:
Once you have a sense as to which category your body fits into in terms of chest shape and extra skin, you will be able to consider which procedure may be the best option for you.
To determine which procedure type is best for you, we first assess your anatomy. Your skin elasticity and the amount of tissue you would like to remove will determine the incisions you qualify for. From there, based on your goals–such as nipple resizing, nipple sensation and chest contour–we can make a more precise, unique, surgical plan for you.
During a free consultation, you and your surgeon will decide together on which procedure would be best for your unique, surgical plan. Your surgeon will likely recommend an incision type based on your anatomy and goals; however, we encourage you to come with your own requests. Our job is to set realistic expectations for what surgery can accomplish for you.
Yes, many insurance providers cover gender-affirming surgery. At the GCC, we have a free insurance concierge team that has a 90% success rate in securing coverage for interested patients.
At the GCC, we do not perform surgery on minors. GCC has no HRT or BMI requirements for top surgery. Rather, we evaluate a patient’s medical history to make a unique surgical plan tailored to keeping a patient safe during surgery and reducing their complication risk.
The double incision technique is performed more than any other procedure for top surgery. This is because it works for a wide range of chest sizes and gives surgeons the most control over results: specifically, creating flat chests.
