Also called capsule release surgery, it cuts the original tightened capsules in circles or crisscrosses with electrosurgical units (ESUs) to expand the contracted implant space. A transaxillary, periareolar, or inframammary incision is created with the aid of an endoscope. Pocket size depends on the severity of contracture, and total or partial capsulotomy can be performed. Implants may not need to be changed but can be upgraded if one desires. Despite having advantages such as less pain, shorter surgical duration, and quicker recovery, capsulotomy does not completely remove the capsules, and some capsular tissue still remains in the body. Therefore, it is ineffective against constitutional, refractory, or potential infectious capsular contracture and may result in recurrence. Thus, patients should pay extra attention to postoperative massage. At present, this surgery is mostly performed on patients with mild to moderate (grade 2-3) capsular contracture or is unilaterally used to adjust uneven implant heights or texture. It is not recommended for grade 4 severe capsular contracture.
