The role of visual evoked potentials in the diagnosis of optic nerve injury as a result of mild head trauma.
The curve of visual evoked potentials was observed and compared with changes of visual acuity and visual field during a 24-month period in a group of 39 patients with optic nerve injury as a result of mild cerebral trauma. Results of the study showed great improvement of visual acuity and visual field after treatment, and slower and continuous improvement of visual evoked potentials. The main abnormality of visual evoked potentials is the shortening of amplitude, which is recorded to gradually recede after treatment in half of the patients. Authors conclude that the shortening of amplitude can be partially explained by the edema and the compression of fibers in the optic canal. Also, they emphasize that in this type of optic nerve injury visual acuity testing is the best indicator of the promptness and scope of the injury, while visual field research presents the best method for following later delicate changes of visual function.

Secondary rhinoplasties for men.
The result of secondary rhinoplasties in men must be absolutely natural. The dorsum, the tip's elevation, and the diverse angles that the nose forms with the rest of the face--that is, shape, dimension, and proportion--must be correct. Illustrative cases of the most frequent defects are presented along with ways to prevent them.

Pinocchio's secondary nose.
The correction of the Pinocchio's nose, either in primary or secondary deformities, poses a difficult problem for plastic surgeons. We propose an original technique with which we obtain excellent results. This technique is based on the elimination of the domes of the alar cartilages and on the placement of a shield graft at the desired height.
Surgical treatment for secondary retracted nose.
This surgical technique is presented to correct nasal tip retraction, which is frequently associated with other surgical sequelae that can be corrected simultaneously. It is based on the use of a shield, an anchor, or half an anchor of otocartilage, with one or two posterior supports that are sutured together forming a small L and are fixed to the bed to project the nasal tip and, if necessary, to correct the unilateral or bilateral alar collapse.
Mammary asymmetry: a brief classification.
A classification of different types of unilateral breast asymmetry is described briefly to emphasize the greater surgical problems of aesthetic correction compared with cases of bilateral pathology.
Correction of the secondary nasal tip and of alar and/or columellar collapse.
The authors present their surgical technique for the correction of the secondary nasal tip with alar and/or columellar collapse. They employ a cartilage autograft in the form of an anchor or half an anchor which is taken from the auricular concha and is designed according to the requirements of the pathology to be corrected. In their experience, they have observed neither complications with the use of these grafts nor unacceptable scars in the columellar incision.
Mammary construction and reconstruction in one surgical stage.
The authors' personal technique for mammary reconstruction, including the nipple-areola complex, is presented. The technique is simple and effective and is performed in only one surgical stage. It is applicable to mammary construction in the case of congenital absence as well as to reconstruction after mastectomy.
Secondary rhinoplasty.
The correction of secondary nasal deformities produced by excessive resection poses difficult problems for the surgeon. We describe our technique using cartilage autografts. Shaping the cartilage carefully, using Rethi's incision, and immobilization of the grafts have yielded excellent results in our patients.
Ear replantation.
The authors' tactical and technical contribution to this type of microsurgical replantation can be summarized in three main points: (1) direct sutures to the superficial temporal vessels, when these are undamaged, which simplifies the operation and makes it safer; (2) use of Kunlin's technique to make up for the great difference in diameter between the arterial vessels; and (3) deepithelialization of the posterior auricular skin to allow for creation of venous drainage channels during the first postoperative days and the enlargement of the area of contact with the recipient bed, which also helps to better immobilize the amputated part.
Correction of the secondary nasal tip.
A technique used concomitantly with Rethi's incision to reach and treat the secondary nasal tip is described. The technique involves removing the cartilage remnants of both domes and placing a shaped cartilage autograft that is immobilized by sutures. No hypertrophic scarring has been observed in the 546 patients treated.
Neighboring flaps and cartilage grafts for correction of serious secondary nasal deformities.
When the secondary nasal deformity is so serious that it presents loss of the soft structures, often its correction requires a neighboring flap besides the cartilage auto-grafts. In such serious cases, which are fortunately infrequent, the surgeon must resort to reconstructive techniques that typically provide very good results. Such is the case with the midforehead Indian flap, which rotated 180 degrees, allows reconstruction of the columella in the same surgical stage. In the same manner, Denonvilliers' flap may be employed to restore contour of the nasal ala, since its scar sequel is very acceptable, and Dieffenbach's flap may be used to reconstruct the columella. The flap of labial mucosa (which other authors have employed to correct septal perforations) is rotated 90 degrees to appose with another similar contralateral flap and is used to correct the seriously retracted columella. In this paper we present some cases that demanded the application of these techniques.
Vertical mammaplasty.
The vertical mammaplasty technique has undeniable advantages over combined techniques. It involves only the inferior pole of the breast, thus avoiding horizontal scars, which are the ones that most frequently hypertrophy. The main disadvantage of the technique is the inferior compensation, leaving visible scars in the thorax. We have modified this technique, making the compensation at the level of the areola. With this procedure, the vertical scar does not go below the submammary fold and is easily concealed.
