Can drains cause capsular contracture?

Thank you for sharing your question and I am sorry to hear of your capsular contracture issues.  Drains are not thought to be a risk factor for capsular contracture development, especially if placed for less than 24 hours.  Leading thoughts on the development of implant hardening is the result of bacterial colonization of the implant and/or any blood that remains in the surgically created implant pocket.  Hope this helps.

The use of drains is to remove the collection of bloody fluid which may accumulate around a breast implant after surgery.  The degree of fluid collection will vary with the individual.  I've noticed most Caucasians do not drain very much and often the drains become light and serous in color within a day or so after surgery.  Many Asians tend to drain much longer usually 5-6 days.  It may a factor of their diet and how active they are after surgery.  Eating lots of garlic, ginger and spicy food leads to a prolonged bleeding time. 

It is a known fact that blood around an implant can stimulate more scar formation.  Also more blood around the implant can increase the chance for colonization of the pocket with bacteria which subsequently causes a biofilm to occur.  These are some of the factors which cause capsules to form.  A capsule that forms a year out in only one of your breast is related to some type of traumatic injury of the breast.  Often it is the dominant side i.e. the right side in a right handed person.  Overuse of the arm and pectoralis muscle can lead to tears in the capsule of the breast with subsequent scarring.  The scars which forms depend on where the tear is and where the blood accumulates.  If the tear is on the top near the pectoralis muscle the upper pole will close.  If the blood collects along the bottom of the breast then the lower pole of the breast will tighten and contract.  This will push the affected implant up higher and create a condition where that contracted breast sits higher than the unaffected side.  Certain activities which is quite vigorous can lead to tears in the breast capsule.  Weight lifting, tennis, golf, surfing, paddling canoes, etc. has been shown to injure the breast capsule when these activities are done within 6 months of the surgery.  It takes time for the capsule of the breast to soften.  Once softened and pliable the capsule is less easily torn and more resistant to injury.
