The technique and results of a new scalp flap that solves frontal baldness are described. As a bipediculate flap it offers a great amount of hair when advanced and has a low rate of complications. This kind of flap has been used by us for four years in 36 patients in the age group between 20 and 60 years. The results obtained with the flap have been very satisfactory.
The results of grafts of fat obtained through liposuction are presented. They are the outcome of the current revitalization of the old technique of fat extraction and transplant. Both doctor and patient should be aware that a successful treatment is achieved through continuity. Fat grafts evolve with respect to time and permanence with reabsorption a part of the normal evolutionary process. Fat reinjection is a consequence of tissue reabsorption or a complement of the preceding injection. There is no complication associated with repeated reinjection. All cases reported here include patients with two or more reinjections, depending on their pathology and evolution.
Autogenous graft tissue is better than homologous and heterologous tissue for the improvement of body contour to eliminate deep defects in the skin surface. This paper presents techniques for fat-graft injection obtained from liposuction and the instruments specially designed for this procedure. An analytical study is presented, and the final results obtained with this method are compared with different filling materials used for aesthetic and reconstructive purposes. A statistical study of 253 operated patients in a long-term follow-up (1984-1988) is registered. Special comments have been included relative to patient recovery, the amount of fat absorption and the amount of fat tissue remaining, and fat injection revisions and complications.
This paper present the method and technical description of the fat graft injection with the material obtained from the same patient (donor area) to correct the affected area (receptor), and also have the finality to remark the good aesthetic results and the patient acceptance. A comparative of the procedure advantage with other filling materials is effected, providing the highly permanence and minimal complications. An evaluation since 1984 is made, referring the innocuousness and facility of the method. We employ the autogenous tissue to make the aesthetic correction of the face wrinkles, nasolabial folds, and depression. With this technique we improve defects like facial atrophy, radiodystrophies, acne, scars, etc. In the same way we use the fat injection in combined procedures with lipoplasty, blepharoplasty, rhinoplasty and facelift. We made this histological study taking postoperative biopsies in some patients.
We report the case of a patient with a large palmar subcutaneous lipoma. The unusual site of the lesion and the importance of a differential diagnosis to rule out angiolipoma are stressed.
We present the idea of correcting soft tissue defects with an injection of fat obtained by liposuction. Our method has great advantages, with few serious complications. The technique is described and the results are demonstrated in several patients treated over a period of one year.
After giving an introduction on the surgical treatment of alopecia in the last years, we talk about our experience with more than 2,500 patients. We discussed in individual chapters each one of the four major methods for the surgical management of male pattern alopecia: punch grafts, strip grafts, scalp reduction, flaps and combined techniques. In general more than the half of those patients have been seen and controlled for long time, because the most of them have continued with the clinic treatment in correspondence with the skin-hair pathology.
A new design for the suction cannula used in suction curettage is presented. Based on several years' experience in patients from 17 to 63 years of age, the new device allows softer movements intraoperatively, a correct grasp, and excellent suction.
