Cervicothoracic prefabricated flaps for reconstruction of face and neck / 中华整形外科杂志

<p><b>OBJECTIVE</b>To introduce a new prefabricated flap with matched colour, texture, thin enough thickness, large enough dimension and reliability for reconstruction of massive defect of face and neck.</p><p><b>METHODS</b>The patients with massive scar of face and neck were selected for treatment with prefabricated flap. Flap prefabrication involved two stages. The "sandwich" structure including the descending branch of the lateral femoral circumflex vessels and surrounding muscle fascia was harvested from the thigh and anastomosed to superior thyroid artery or facial vessels. Flap prefabrication was performed by inserting the fascia flap between the cervicothoracic skin and the tissue expander placed beneath the skin. After a period of expansion, the flap was transferred to the recipient site based on the implanted vessels. The results including complications were examined during follow-up.</p><p><b>RESULTS</b>Nine patients received this treatment. The average dimensions of fascia flap harvested was 6.3 cm x 11.2 cm. After mean interval of 16.7 weeks, the expanders were filled to a mean volume of 1670cc. The size of prefabricated flap ranged from 12 cm x 15 cm to 15 cm x 32 cm. In all cases, the flap efficiently covered the entire defect of the face and neck, and the donor site of the flap is closed primarily. All of the flaps developed venous congestion in some degree after the second operation. Partial flap necrosis occurred in two cases. Three flap was thinned to contour the bulky pedicle. During follow-up, the transferred flap was matched well to the adjacent skin. The reconstructed face restored nature contour and expression. Muscle weakness or paraesthesia was not found in the donor thigh.</p><p><b>CONCLUSIONS</b>Cervicothoracic Prefabricated Flap, is reliable and versatile in the reconstruction of massive soft tissue deficits with restoration nature surface and expression of the face and neck.</p>

Application of aesthetic sub-unit principle in nasal reconstruction and repairing of nasal defects / 中华整形外科杂志

<p><b>OBJECTIVE</b>To evaluate the significance and effect of nasal aesthetic sub-unit principle.</p><p><b>METHODS</b>Based on nasal aesthetic sub-unit, 27 patients were divided into 5 groups according to their nasal defects. They were nasal dorsum, tip, alar lobule, soft triangle and two or two above nasal subunit defects groups. Local restore were applied in defects which were less than 50 percent of one nasal subunit. Total nasal subunit reconstruction were applied, if areas of defects were larger than 50 percent of one nasal subunit 10 cases were received free tissue transplantation (including free skin transplantation, composite auricle transplantation, etc), 4 cases were received local flap, and 13 cases were received forehead flap. Following up for 5 to 37 months, evaluation item were contour and color.</p><p><b>RESULTS</b>Skin transplantation and local flap were all survived. Auricle composite flap were all survived except for 2 cases whose epidermis looked red and purple. These two case's epidermis regained normal 6 months after operation. Forehead flap for nasal reconstruction were all survived, but one of them had to perform secondary surgery for coverage of the exposed nasal frame. 27 cases were followed up in all. Patients and their family members were satisfied with the nasal's contour and color.</p><p><b>CONCLUSIONS</b>Good aesthetic effects comes from nasal aesthetic sub-unit principle in nasal reconstruction and repairing of nasal defects.</p>

Three case reports of abdominal compartment syndrome after full abdominoplasty / 中华整形外科杂志

<p><b>OBJECTIVE</b>To improve the safety of the abdominoplasty by the study of the complication of abdominal compartment syndrome after abdominoplasty.</p><p><b>METHODS</b>Three cases were analyzed and discussed respectively in aspects of clinic symptoms, pathological reason, treatments and follow-up results. The treatment was the incision of musculoaponeurotic system, which usually cause defect of abdominal wall after pressure releasing. The defect of musculoaponeurotic system was reconstructed by Mesh, and the defect of skin was repaired by skin graft.</p><p><b>RESULTS</b>The pathologic change of the complications was the shrinking of the belly cavity's volume and the increasing internal pressure of the abdomen caused the internal pressure of the thoracic cavity increase. The clinical manifestations included compressive feelings of chest and abdomen, high urinary frequency and psychiatric symptom. 2 patients accepted the operation. The abdominal compartment syndrome disappeared after the operation, and the results of the two years follow-up were satisfied.</p><p><b>CONCLUSIONS</b>Full abdominoplasty has the risk of causing abdominal compartment syndrome. This complication can be cured by decompression of abdominal wall. The effect is stable after long time's follow-up. Special preventive methods should be used in high-risk patients to avoid this complication.</p>

Repair of nasal lining in nasal reconstruction / 中华整形外科杂志

<p><b>OBJECTIVE</b>To present a variety of techniques for providing nasal lining and discuss the application of these methods to specific nasal defects.</p><p><b>METHODS</b>Regard of the nasal defect's location, size, or depth of involvement, the approaches were used with turnover nasal skin or scar flaps (n=17), the buccal mucosal flap (n=1), the nasolabial flaps (n=5), prefabricated flaps (n=1) for lining. A formal nasal reconstruction was then carried out with use of rib cartilage grafts for support and a forehead flap for cover.</p><p><b>RESULTS</b>Necrosis of forehead flaps and lining tissues did not occur. 24 Cases have been followed for a 6-34 months period. Except some turnover scar flaps obstructed the airway and needed aggressive secondary surgical thinning, the other lining flaps remained stable from adequate restoration of form and function.</p><p><b>CONCLUSIONS</b>It is important to evaluate the exact sizes, volumes and layers missing of the nasal defects before rebuilding the lining defect. Choosing the adequate operation can provide good aesthetic and functional results. The prefabricated flap is good to be used to reconstruct nasal lining in complicated cases.</p>

Anatomic study of supratrochlear artery and its application in nasal reconstruction / 中华整形外科杂志

<p><b>OBJECTIVE</b>To study the anatomy of the cutaneous branch (CB) of supratrochlear artery and its relevance to the design of frontal flap in nasal reconstruction.</p><p><b>METHODS</b>10 fresh cadavers were dissected to study the position and course of the CB of supratrochlear artery (supraorbital rim and facial midline as landmark). The communication between the CB and supraorbital artery was also studied. 5 cases of ultra-thin frontal flaps and 11 cases of bi-flap( cutaneous flap and muscular flap) were designed on anatomic basis. The survival rate of flap, the stability and aesthetic appearance of the reconstructed nose were followed up.</p><p><b>RESULTS</b>The supratrochlear artery gave off constant CB (1.18 +/- 0.36) cm from upper orbital rim and (1.35 +/- 0.34) cm from the midline of face. The CB passed in a subcutaneous plane and communicated with the bilateral muscular branch, CB of the opposite side and bilateral supraorbital artery. The supratrochlear artery only had CB with no muscular branch in 3 cases. All the flaps survived completely except one with blister on the nose tip which healed spontaneously. The postoperative aesthetic appearance was very satisfactory.</p><p><b>CONCLUSIONS</b>The supratrochlear artery has constant CB. The frontal ultra-thin flap pedicled with the CB can improve the therapeutic effect of nasal reconstruction.</p>
