Article
The purpose of this study was to analyze our experience with the influence of reconstructive techniques at the time of pelvic exenteration on morbidity. Between June 1986 and December 1998, 60 pelvic exenterations for gynecologic malignancies were performed in our hospital. Forty-five were selected for this study because they met two criteria: they...
Article
We have carried out a study to determine if a flap based on vessels in the fourth metacarpal space could be used safely. We studied ten fresh cadaver specimens and used the flap in nine patients. In the anatomical study, we confirmed the presence of a suitable artery in nine out of the ten hands, arising from a piercing artery at the metacarpal bas...
Article
We describe a new technique for the surgical reconstruction of large-sized anterior septal perforations based on the pericranial flap. The technique requires a standard open rhinoplasty combined with a pericranial flap harvested after a bicoronal approach and tunnelled to the nasal cavity. We present the case of a man with complete destruction of t...
Article
We have done an experimental study in lambs in which we investigated the influence of flow rate on free microvascular flaps using polytetrafluoroethylene (PTFE) vascular grafts. We set up five surgical groups in which blood flow was progressively increased through the PTFE vascular graft. In group I (venous autograft) we observed just one vascular...
Article
Primary amyloidosis is a systemic disease. Amyloid arthropathy is an invalidating and uncommon form of presentation, but tenosynovitis is even rarer as the first sign of the disease. We report herein a case of unilateral amyloid deposit in the synovium of the extensor tendons of the hand, which was the first manifestation of a primary amyloidosis.
Article
The authors present 3 patients with subconjunctival fat prolapse treated at their oculoplastic unit. Albeit rare, orbital fat is a well-recognized entity, and is described in the literature as being associated with trauma and surgery. The 3 patients reported herein, however, presented with no history of trauma or surgery. This condition is produced...
Article
The problem of pharyngostomic closure is difficult to solve, as evidenced by the large number of techniques described. The authors present the reconstruction of pharyngostomes by using Bakamjian's deltopectoral flap modified by the use of endoscopically introduced expanders for those patients in whom other techniques of choice (such as vascularized...
Article
In cranioplasty complexity is proportional to the size of the defect, particularly if greater than 50 cm2. If the patient's own bone flap is not available, allogenic frozen bone graft can be used instead. Between June 1990 and June 1995 twenty cranioplasties with allogenic frozen bone grafts were performed. Age of patients ranged between 23 and 63...

It is well known that calvarial bone autografts are the bone grafts that are the least reabsorbent and have the best long-term evolution in craniofacial surgery. However, they do have certain limitations: (1) reabsorption results in repeated surgery and the need for new donor areas, (2) a limited amount of autogenous cranial bone is available (due...
Article
In head and neck surgery, the need frequently arises to work in close proximity of the facial nerve. Considering its anatomical variations and the consequences of its iatrogenic injury, the authors believe it is convenient to utilize all of the resources to avoid the possibility of an injury. Since 1992, the authors utilized a system of intraoperat...
Article
In this comparative study, we carried out liposuction on 20 patients randomly divided in two groups to find an alternative medication to epinephrine that would not result in secondary effects at the cardiovascular level but would offer a similar vasoconstricting capacity. Also, a variation of the wet technique is described that decreases blood loss...
Article
Dynamic cardiomyoplasty is a technique for ventricular assistance indicated for the correction of left ventricle aneurysm and for cardiomyopathies in which heart transplantation is contraindicated. In this article, our first four patients to undergo cardiomyoplasty (from February 1991 until April 1992) with a left latissimus dorsi island flap, rota...
Article
A modification of the Abbe-McIndoe technique for the treatment of congenital absence of the vagina, using a cylindrical tissue expander wrapped in a mesh split-thickness skin graft, instead of a rigid silicone mold, is presented. The expander was kept in place for a period of two to six months and the functional result was 100 percent in all the si...
Article
We present the case of a patient with Barraquer-Simon's progressive lipodystrophy syndrome whose facial deformity was treated by means of rotation of the temporalis muscles, which produced good facial symmetry.
Article
We present a technique for reconstruction of the legs in patients with soft-tissue loss and formation of large scars with retraction of this tissue in the pretibial region. In such patients, a subcutaneous tissue expander is placed in the region adjacent to the scar tissue. With expansion, we obtained sufficient skin for use in the reconstruction,...
Article
The use of a vascularized graft from the fibula for mandibular reconstruction is presented. The great strength, pliability, and long vascular pedicle that characterize such grafts make them particularly suitable for this type of repair. The results in six cases were highly satisfactory. Masticatory function was well restored, without alteration of...
Article
In oncology jaw reconstruction, the probability of infection, sequestration and failure in scarring is high. For this reason, we use a vascularized free bone graft, whose direct blood flow makes it much more resistant to support the attendant properly. The use of bone scintigraphy by means of three phases acquisition technique is very effective to...
Article
Our surgical protocol for reconstruction of eyelid's defects after tumor excision is presented. Each technique is applied depending on the site and extension of the lesion and also on the pathologic characteristics of the tumor.

... All these precautions, together with management of infection by exteriorizing the buried ports, improved the results of this study. Casanova et al. [29] mentioned other precautions to improve results in limb expansions (1) careful preoperative planning [6,18,30,31], (2) proper expander size should be chosen with care to prevent folds in the silastic envelope [18,31], (3) areas of scarring or previous irradiation should be avoided [18,31], (4) the prostheses chosen for a limb should be as numerous as possible and shaped so that no skin is left unexpanded [31], and (5) the expanders should be placed longitudinally, if possible, because it is more difficult to create adequate flaps for axial use than for transverse use in the leg [16]. Casanova et al. [29] discussed the advantages of external valves. ...
... 2,3 The vascularized fibula has been considered the first-line treatment of mandibular defects due to several advantages over the other vascularized bones. 3,4 However, in certain situations where the fibula is not available, such as peripheral vascular disease or peroneus magnus, an alternative flap is essential. 5 Researchers have described the use of the clavicle as a free vascularized bone in the reconstructive field. ...

... It is also important that the incision does not intersect the implant bed at any point. To prevent this, the distance from the incision line to the implant should be at least 1.5 cm (Kempf et al., 1999;Manrique et al., 1995;Webb et al., 1991). ...
... The latissimus dorsi myocutaneous flap (LDMF) is another technique for ventricular assistance indicated for the correction of cardiomyopathies when heart transplantation is contraindicated [18]. In this procedure, a transformed skeletal muscle (latissimus dorsi) is wrapped around the heart to augment cardiac pump function [19]. ...
