Understanding Uniboob (Symmastia): Causes, Prevention, and Treatment Options

Uniboob, medically known as symmastia, occurs when the breast tissue merges across the midline of the chest, creating the appearance of a single, continuous breast. While this condition can occur naturally, it's often associated with complications from breast augmentation surgery. Here's a closer look at the causes, prevention strategies, and treatment options for symmastia. Causes of Uniboob (Symmastia) Symmastia can occur due to various factors, both natural and surgical: Congenital Symmastia: Some individuals are born with symmastia, where the skin and tissue between the breasts are naturally less defined. Breast Augmentation Complications: The most common cause of acquired symmastia is breast augmentation. If implants are placed too close to the midline or are too large for the patient’s chest width, the pressure can cause the skin between the breasts to lift, resulting in the “uniboob” effect. Overdissection: During breast augmentation, if the surgeon creates pockets that extend too far towards the middle of the chest, the implants can shift, leading to the merging of the breasts. Tissue Weakness: Thin or weakened tissue in the chest can also contribute to symmastia, making it more likely to develop after surgery, especially with larger implants. Preventing Uniboob Preventing symmastia, especially during breast augmentation, involves careful planning and surgical technique. Here are a few ways to minimize the risk: Proper Implant Sizing: It’s crucial to select implants that are appropriate for the patient’s chest dimensions. Implants that are too large can increase the risk of uniboob by pushing the breast tissue toward the center. Skillful Surgical Technique: A well-trained and experienced plastic surgeon will be cautious about overdissection and ensure that the pockets created for the implants do not extend too far towards the midline. Use of Internal Bra Technique: Some surgeons may use an internal bra or special sutures to help support the implants and keep them in place, preventing them from shifting toward the center of the chest. Adequate Healing Time: Post-operative care is critical to avoid implant migration. Patients should follow their surgeon’s guidelines carefully, including wearing supportive garments and avoiding certain movements that could stress the healing tissue. Treatment Options for Symmastia If uniboob does occur, there are corrective options available. Treatment typically involves surgical intervention: Revision Surgery: A plastic surgeon can perform a revision to correct symmastia by repositioning the implants, closing the pocket toward the midline, or using an internal bra technique to provide better support. The goal is to recreate a natural-looking cleavage and separate the breasts. Tissue Reinforcement: In cases where the tissue is weakened, surgeons may use tissue reinforcement materials such as acellular dermal matrix (ADM) or other synthetic meshes. These materials provide additional support and help prevent the recurrence of symmastia. Fat Grafting: Fat grafting may be used to add volume to the area between the breasts and further define the cleavage. This technique can enhance the results of revision surgery by creating a more natural appearance. Non-Surgical Options: While non-surgical treatments like ultrasound or laser therapies may improve the skin's elasticity and healing post-surgery, they are not effective in correcting severe cases of symmastia. Conclusion Uniboob, or symmastia, can be a distressing condition, particularly for those who experience it after breast augmentation. However, with advances in surgical techniques and careful planning, it’s possible to prevent and treat this condition effectively. Choosing a highly experienced plastic surgeon and following post-operative care instructions are key steps in achieving the best outcomes and minimizing the risk of complications like symmastia.
