[Reduction mammaplasty according to McKissock's technique. A review of 312 cases].

312 cases of reduction mammaplasty performed over a period of 12 years according to McKissock's technique are reviewed. This technique is characterised by a pre-established drawing, a vertical nipple-bearing bipedicle flap, and perfectly defined cutaneo-glandular resection according to three blocks. it is indicated in almost 70% of women between the ages of 20 and 50 years with an equal distribution by 10-year age-groups. The remaining 30% are equally divided between women under the age of 20 years and women over the age of 60 years. Reduction mammaplasty is performed after menopause in 30% of cases. Maintenance of the results at two years and projection of the ANC are perfectly satisfactory. On the basis of these cases, secondary ptosis does not appear to be more severe with this technique and secondary glandular resorption is also unlikely. No necrosis of the ANC was observed in this series. In conclusion, this technique achieves aesthetic symmetrical breasts with long scars under very good conditions of safety. Shortening of the scars could only be achieved to the detriment of the shape of the breasts.
