Thank you for the question.
Breast reduction surgery is one of the most patient pleasing operations we perform. Exactly what is done during this procedure can be individualized to each patient's specific situation/needs/goals. For example, if a patient states that she wishes to treat breast tissue close to the axillary area ( this breast tissue is called the axillary tail of Spence), then the area can be treated during the breast reduction procedure. Sometimes, excision of breast tissue in this area requires an additional incision to remove skin as well as the “redundant” breast tissue involved. Other times, liposuction surgery may be effective. Again, much of what is recommended will depend on the individuals specific situation. Factors such as quality of skin elasticity play an important part as to what modality of treatment would work best.
Furthermore, if the patient has localized adipose tissue of the upper back/chest area, this may be treated at the same time as breast reduction. Sometimes direct excision ( lipectomy) of the involved area is necessary to improve the contour of the involved area. At other times, liposuction alone will suffice.
Of course, direct excision of any redundant skin/tissue will result in additional scarring; the pros/cons of these types of the decisions should be considered carefully. Some patients will accept additional scarring as a trade-off for improvement in the contour of the axillary or back areas.
Again, it will be important for every patient to communicate their concerns/goals carefully with their plastic surgeon prior to proceeding with surgery.
I hope this helps.
