RESUMEN

Explantation of breast implants has become increasingly common. This study aimed to analyze breast auto-augmentation following implant explantation (using a laterally designed anterior intercostal artery perforator [AICAP] flap) in patients who did not need new implants and required volume preservation. Twenty-four patients (48 breasts) aged 31-67 years (mean, 52.4 years) with body mass index (BMI) between 24.43 and 29.34 (mean, 27.32) kg/m2 underwent this procedure. All patients had implant-related problems, such as recurrent capsular contracture (n=11), seroma (n=2), animation deformity (n=3), rupture-induced bleeding (n=5), and breast implant disease (n=3). Sizes of implants removed ranged from 215 to 355 ml. The mean flap size was 23.9 cm × 7.5 cm, and the average flap thickness was 2.3 cm (range, 2.0-3.2 cm). Flap survival was clinically examined postoperatively by ultrasonography. Pre- and postoperative final breast volumes were compared by direct patient observation and independent photograph observation by three plastic surgeons according to a 4-point scale (bad=1, regular=2, good=3, and excellent=4) and the brassiere size. All flaps were completely viable after harvesting. No postoperative signs of fat necrosis were observed, and independent plastic surgeon evaluation revealed good and excellent results in all cases. Patient satisfaction evaluated by BREAST-Q data was >90%. This new design, AICAP flap (with a lateral thoracic extension), can be safely used for breast volume restitution after breast implant explantation with high patient satisfaction. This flap exhibited reasonable potential of providing additional volume in patients who undergo implant explantation and require the preservation of similar volume.

RESUMEN

Los cirujanos plásticos nos enfrentamos cada vez con más frecuencia en nuestra consulta a pacientes que desean o necesitan retirar sus implantes mamarios. Algunas de estas pacientes rechazan la idea de un reemplazo protésico, pero son exigentes con el resultado cosmético postoperatorio. Describimos la técnica empleada en 68 casos consecutivos y los resultados que hemos obtenido al tratar las secuelas en la mama tras la retirada de los implantes, fundamentalmente una disminución de volumen asociada a ptosis y excedente cutáneo. Esta técnica se basa en la extracción de los implantes y correccion mamaria simultanea con colgajo dermoglandular inferior que denominamos "autoprotesis" asociado a injerto graso simultáneo. Los resultados logran mejorar la forma, proyección y conificacion de la mama tras la retirada de los implantes, con un alto grado de satisfacción por parte de las pacientes (AU)


Plastic surgeons are frequently faced during consultation with patients who want or need breast implant explantation. Some of these patients reject the idea of a prosthetic replacement, but are demanding with the postoperative cosmetic result. We describe the technique used in 68 consecutive cases and our results to deal with breast alterations after breast implant explantation, leaving a decreased mammary volume, ptosis and a loosy cutaneous excedent. With this technique of explantation and simultaneous breast correction with de-epithelialized dermoglandular flap, "authoprosthesis", associated with simultaneous fat grafting, we can get a good result regarding the shape, projection and coning of the explanted breast, with high patient satisfaction (AU)

RESUMEN

El compromiso del seno frontal con fractura de sus paredes es un tipo de lesión infrecuente, en torno al 5-12% de todas las fracturas faciales. Suele asociarse a lesiones intracraneales, oftalmológicas y a otras fracturas máxilofaciales y cuando conlleva fractura de la pared posterior de seno frontal requiere tratamiento inmediato, siendo necesaria la obliteración del seno frontal debido a la comunicación con meninges y lóbulo frontal, con el riesgo infeccioso que ello representa. Tratamos 18 pacientes con traumatismos craneofaciales y fracturas del seno frontal con compromiso de su pared posterior en el periodo comprendido entre 2007 y 2011; 8 mujeres y 10 varones con edades comprendidas entre los 15 y los 64 años. Todos los casos fueron tratados con reducción y osteosíntesis por vía abierta con distintos abordajes y realizamos en todos colgajos pediculados de vecindad. La vitalidad de los colgajos fue del 100%. Certificamos el posicionamiento correcto mediante tomografía axial computarizada. El tratamiento de las fracturas del seno frontal con compromiso de su pared posterior o del conducto nasofrontal requiere obliteración con tejido vascularizado para evitar comunicaciones con la cavidad nasal (AU)


The commitment of the frontal sinus with involvement of its walls is a rare lesion, around 5-12% of all facial fractures. It's usually associated with intracranial, ophthalmologic, maxillofacial fractures and other injuries, and when there is a fracture of the posterior wall, requires immediate treatment with frontal sinus obliteration due to communication with meninges and frontal lobe because of infectious risk. We treat 18 patients with craniofacial trauma and fractures of the frontal sinus with involvement of the posterior wall in the period between 2007 and 2011, 8 women and 10 men, aged between 15 and 64 years. All cases were treated with open reduction and internal fixation using different appoaches and using adjacent pedicle flaps. The vitality of the flaps was 100% . We certify the correct positioning by computed tomography. The treatment of the fractures of the frontal sinus with involvement of the posterior wall or of the nasofrontal duct require obliteration with vascularized tissue to prevent communication with the nasal cavity (AU)

RESUMEN

Avatar carries a pejorative connotation often related to an unfortunate hazard. In face transplants, incarnations were numerous. The analysis of their evolution through time and increasing sophistication of procedures turn out to be informative regarding the wide disrepairs in the craniofacial area. The authors report the principal constraints of face transplant and the evolution in minds to deal with it.

RESUMEN

La espalda es una excelente zona dadora de colgajos. El colgajo perforante tóracodorsal basado enramas cutáneas de la arteria y vena tóracodorsales que perforan el músculo dorsal ancho, es una modificación del tradicional colgajo musculo cutáneo de dorsal ancho que permite lograr una mayor flexibilidad en su traslado y una disminución de su volumen. Puede emplearse como colgajo libre o en isla. Presentamos su anatomía, disección e indicaciones (AU)


Back is an excellent donor site for flaps. The toracodorsal perforator flap, based on cutaneous vessels from toracodorsal artery and vein that pass through Latissimus Dorsi muscle, is a modified conventional musculocutaneous Latissimus Dorsi flap that allows easier movility and a volume reduction. This flap can be used both, free flap or island flap. We present the anatomy, dissection and applications of this flap (AU)

RESUMEN

Skin flaps from the medial aspect of the thigh have traditionally been based on the gracilis musculocutaneous unit. This article presents anatomic studies and clinical experience with a new flap from the medial and posterior aspects of the thigh based on the proximal musculocutaneous perforator of the adductor magnus muscle and its venae comitantes. This cutaneous artery represents the termination of the first medial branch of the profunda femoris artery and is consistently large enough in caliber to support much larger skin flaps than the gracilis musculocutaneous flap. In all 20 cadaver dissections, the proximal cutaneous perforator of the adductor magnus muscle was present and measured between 0.8 and 1.1 mm in diameter, making it one of the largest skin perforators in the entire body. Based on this anatomic observation, skin flaps as large as 30 x 23 cm from the medial and posterior aspects of the thigh were successfully transferred. Adductor flaps were used in 25 patients. On one patient the flap was lost, in one the flap demonstrated partial survival, and in 23 patients the flaps survived completely. The flap was designed as a pedicle island flap in 14 patients and as a free flap in 11. When isolating the vascular pedicle for free tissue transfer, the cutaneous artery is dissected from the surrounding adductor magnus muscle and no muscle is included in the flap. Using this maneuver, a pedicle length of approximately 8 cm is isolated. In addition to ample length, the artery has a diameter of approximately 2 mm at its origin from the profunda femoris artery. The adductor flap provides an alternative method for flap design in the posteromedial thigh. Because of the large pedicle and the vast cutaneous territory that it reliably supplies, the authors believe that the adductor flap is the most versatile and dependable method for transferring flaps from the posteromedial thigh region.

RESUMEN

The vascular supply of the Le Fort I osteotomy segment was studied by utilizing standard latex injection techniques. Anatomic dissections in 10 fresh cadavers demonstrated interruption of the descending palatine arteries with preservation of the ascending palatine branch of the facial artery and the anterior branch of the ascending pharyngeal artery within the attached posterior palatal soft-tissue pedicle in all specimens following Le Fort I maxillary osteotomy. These ascending arterial branches entered the soft palate at a position approximately 1 cm posterior to the pterygomaxillary junction, which was disrupted during the Le Fort I maxillary osteotomy. Separate ink injections of total maxillary osteotomy segments confirmed vascular perfusion of the ipsilateral hemimaxillary segment by the ascending palatine artery. Thus vascular supply of the mobilized Le Fort I maxillary segment is by means of the ascending palatine branch of the facial artery and the anterior branch of the ascending pharyngeal artery in addition to the rich mucosal alveolar anastomotic network overlying the maxilla.

RESUMEN

A bilateral extended scapular (scapular-parascapular) free flap was used in five patients with severe facial burn sequelae for complete resurfacing of the face with the exception of the nose, which was reconstructed in a separate operative procedure. All the flaps survived. Four were utilized for complete face resurfacing and one for neck and partial face resurfacing. The results were classified subjectively according to both patient and surgeon opinion. Good to fair results were obtained. The authors believe that this method might be further explored to obtain better results in these difficult cases.

RESUMEN

Parascapular free flaps traditionally have been designed obliquely across the back, corresponding to the descending branch of the circumflex scapular artery. The donor site of this workhorse flap has the drawback of a widened and frequently hypertrophic scar. In searching for aesthetic improvements in the donor site, we have progressively rotated the axis of this flap in an anterior direction. The end result of this modification is the flap we report here: the inframammary extended circumflex scapular flap. This flap has a longitudinal axis of rotation lying curvilinearly from the inframammary fold to the circumflex scapular artery within the triangular anatomic space. We have used this flap in 20 patients over the past 2 years. The vast majority of these cases were deepithelialized flaps with customized extensions of dorsal thoracic fascia to correct facial asymmetry. We feel that the inframammary extended circumflex scapular artery flap donor-site scar is well hidden within the inframammary fold, and that the unavoidable widening and hypertrophy of parascapular and scapular flap donor-site scars were minimized compared with traditional flap designs.

RESUMEN

The possibility of raising the cutaneous island of the latissimus dorsi musculocutaneous flap without muscle based on only one cutaneous perforator is presented in this paper. An anatomic study performed in 40 fresh cadaver specimens injected with colored latex demonstrated that the vertical intramuscular branch of the thoracodorsal artery gives off two to three cutaneous branches (perforators) that are consistently present. The largest one, measuring approximately 0.4 to 0.6 mm in diameter, provides the blood supply to a 25 x 15 cm cutaneous island. The incorporation of the proximal trunk of the thoracodorsal artery lengthens the pedicle, facilitating the anastomosis or the arc of rotation (in the case of island flaps) but does not increase the amount of tissue transferable. Five clinical cases were done with this technique without tissue necrosis or flap loss.

RESUMEN

Se presenta la experiencia clínica de 28 reconstrucciones mamarias con colgajo transverso abdominal libre con microanastomosis vascular realizada desde 1991 en el Servicio de Patología Mamaria del Hospital Fiorito de Avellaneda. Se manifiesta la preferencia por la reconstrucción inmediata. Se presenta la posibilidad de realizar el colgajo TRAM (transverso abdominal) con una sola perforante sin músculo y sin aponeurosis abdominal con lo que se disminuye notoriamente la morbilidad de la zona dadora. De los 28 casos realizados hubo una pérdida total del colgajo atribuible a razones técnicas. No hubo sufrimientos parciales una vez transferido. El resultado estético fue bueno excepto en los casos con radiodermitis o radiofibrosis en la zona mamaria que impidió una colocación adecuada del colgajo. La comparación con una serie de colgajos TRAM en la isla realizados por uno de los autores reveló que la transposición en forma libre facilita la colocación del colgajo y asegura más su irrigación; por último esta técnica permite la anulación de las secuelas de la zona dadora.

RESUMEN

In the paraplegic patient who has had previous surgeries for pressure sores, local tissue is frequently unavailable for further use. The posterolateral aspect of the thigh, however, is almost always available and provides an excellent reconstructive alternative for this difficult problem. In 1983, Baek described the skin territory supplied by the third perforator of the profunda femoris artery. A musculocutaneous flap can be raised consisting of the same skin territory and a portion of the biceps femoris muscle (short head) through which the third perforator courses. In addition, the distal part of the vastus lateralis muscle, which is supplied by a muscular branch of the same perforator, can be included in the flap. The flap is elevated as an island based on the profunda femoris artery and accompanying venae comitantes. A substantial soft-tissue mass can be transposed easily to the perineum. Standard latex injection techniques were used in 12 fresh cadaver dissections prior to use of this flap in 16 clinical cases. Selective india ink injections into the third perforator of the profunda femoris artery in 6 cadavers confirmed the perfusion of the overlying skin territory. Recurrent ischial and perineal wounds were closed successfully with this musculocutaneous flap in all 16 clinical cases.

RESUMEN

Eighty-six patients with anterior neck burn sequelae underwent scar resection up to the limits of the aesthetic unit of the neck and immediate resurfacing with a scapular-parascapular free flap (the extended scapular flap). The flap was raised in all patients above the deep fascia as a thin skin-subcutaneous tissue flap, providing an initially acceptable aesthetic result. The flap was anastomosed to the facial artery and vein. The donor area was closed directly, or a 4- to 5-cm-wide skin graft was used which could be completely removed in a secondary procedure if the patient requested it. There were four failures early in the series but no losses in the last 70 patients. In order to improve the final aesthetic result, 45 patients underwent complementary defatting procedures (average of three) and Z-plasties initiated 30 days after the initial surgery at intervals of 1 month. Analysis revealed 96 percent good aesthetic results (as determined by the cervicomental angle obtained and the subjective opinion of the patients). There were no recurrences of scar contractures, and good function of the neck was regained in the majority of the patients. Anterior neck burn sequelae thus can be safely treated with en block resection and resurfacing using this flap.

RESUMEN

The results of an anatomic investigation performed in 40 fresh cadaver specimens and 80 consecutive clinical cases of the posterior interosseous reverse forearm flap are reported. It was observed that there is a choke anastomosis between the recurrent dorsal branch of the anterior interosseous artery and the posterior interosseous artery at the level of the middle third of the posterior forearm. Ink injections through a catheter placed in the distal part of the anterior interosseous artery stained the distal and middle thirds of the posterior forearm, but the proximal third remained unstained; this secondary territory cannot be captured through the choke anastomosis between the anterior interosseous artery and the posterior interosseous artery. Intravital fluorescein injection into the distal arterior interosseous artery revealed (under ultraviolet light) that the distal third of the posterior forearm is irrigated by direct flow through the recurrent branch of the arterior interosseous artery (the traditionally called distal anastomosis of the interosseous arteries). Therefore, we can assume that the blood flow is not reversed when the so-called posterior interosseous reverse forearm flap is raised. From this point of view, this flap could be renamed as the recurrent dorsal anterior interosseous direct flap; however, the classical name is maintained for practical purposes. From the venous standpoint, the cutaneous area included in this flap belongs to an oscillating type of venous territory and is connected to the deep system through an interconnecting venous perforator that accompanies a medial cutaneous arterial branch located at 1 to 2 cm distal to the middle point of the forearm.(ABSTRACT TRUNCATED AT 250 WORDS)

RESUMEN

Nonunion and avascular necrosis after scaphoid fractures continue to be problem sequelae because of unrecognized injuries, inadequate immobilization techniques, or insufficient treatment time. Screw fixation and inlay bone grafting techniques remain the options of choice, with successful union reported in approximately 90% of patients. However, prolonged immobilization with plaster up to 4 to 6 months is required with conventional techniques. With the use of standard latex injection techniques with vascular filling of vessels to less than 0.1 mm diameter in ten fresh cadaver dissections, we discovered a consistent vascularized bone graft source from the distal dorsoradial radius. We have used this vascularized bone graft source with good results in eleven patients with long-standing nonunion of the scaphoid. It is technically easy and seemingly offers the advantages of a decreased period of immobilization and a higher union rate.

RESUMEN

The skin of the dorsal aspect of the forearm is supplied by several cutaneous branches of the posterior interosseous artery. This vascular anatomy permits the surgeon to obtain an island flap of the dorsal forearm based on the distal anastomosis between the two interosseous arteries at the distal part of the interosseous space. This flap can reliably be transferred to different skin defects of the hand such as those created by correction of an adduction contracture of the first web space, or on the back or front of the wrist level. Its principal advantages are that it is a thin flap with excellent circulation and that it is possible to close the donor area primarily provided the island flap is not wider than 3 to 4 cm. The procedure has been employed in 25 patients with satisfactory results.

RESUMEN

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.
