  • EFFECTIVENESS OF PERICHONDRIAL CUTANEOUS GRAFT OF DORSAL AURICLE FOR REPAIRING FACIAL MELANOCYTIC NEVUS EXCISION DEFECT

    Objective To investigate and compare the effectiveness of perichondrial cutaneous graft (PCCG) of dorsal auricle for repairing defect after excision of melanocytic nevus in different parts of the face. Methods Between February 2008 and October 2012, 29 cases of facial melanocytic nevus were admitted. There were 11 males and 18 females, aged 3-25 years (median, 11 years). The locations were the upper eyelid in 5 cases, the nose in 15 cases, and the buccal region in 9 cases. The size of the nevi ranged from 1.2 cm × 1.0 cm to 4.0 cm × 2.2 cm. Defects after excision of nevi were repaired by PCCG of the dorsal auricle, which size ranged from 1.5 cm × 1.5 cm to 4.2 cm × 2.5 cm. The postoperative effectiveness was scored by patients according to color match, scar formation, and flatness of the reception site. The satisfaction evaluations were compared by the score among different parts. Results All the PCCG survived. All the patients were followed up 7-15 months (mean, 10 months). All the reception site had good color match and acceptable scar formation. The nasal part had good flatness, and the upper eyelid had poor flatness. Score comparison showed no significant difference in color match between 3 parts (P gt; 0.05). Nasal part had significantly less scar formation than buccal region and upper eyelid (P lt; 0.05), but no significant difference between buccal region and upper eyelid (P gt; 0.05). Nasal part and buccal region both had significantly better flatness than upper eyelid (P lt; 0.05), but no significant difference between nasal part and buccal region (P gt; 0.05). The overall evaluation score of nasal part and buccal region was significantly higher than that of the upper eyelid group (P lt; 0.05), and the score of the nasal part was significantly higher than that of the buccal region (P lt; 0.05). Conclusion PCCG of dorsal auricle has a good color match in repair of facial defect, especially in repair of nasal defect with good flatness and no obvious scar formation.

  • MENTOCERVICAL RECONSTRUCTION AND EFFECTIVENESS EVALUATION IN TREATMENT OF MENTOCERVICAL CICATRICIAL CONTRACTURE DEFORMITY

    Objective To investigate the procedures and effectiveness of platysma scar flap for reconstructing mentocervical appearance in patients with mentocervical cicatricial contracture deformity. Methods Between April 2004 and August 2011, 26 patients with mentocervical cicatricial contracture deformities were admitted. There were 15 males and 11 females, aged 12-31 years (mean, 18 years). The causes included scald injury in 19 cases and flame injury in 7 cases, including 23 cases of deep second degree burn and 3 cases of third degree burn. The time between injury and scar formation was 6-27 months (mean, 10 months). The mentocervical angle was (117.10 ± 14.46)°, and the cervicomental angle was (143.38 ± 15.68)°. The platysma scar flap transfer (8 cm × 7 cm to 10 cm × 8 cm in size) and skin grafting were performed to reconstruct mentocervical appearance. Results The flap and skin graft all survived and the incisions healed by first intention. All the patients were followed up 6 months-3 years (mean, 16 months). The mentocervical and cervicomental angles were significantly reduced to (89.31 ± 6.30)° and (117.83 ± 10.65)° respectively at 2 weeks after operation (P lt; 0.05), showing no significant difference when compared with normal mentocervical angle (90°) and cervicomental angle (120°) (P gt; 0.05). The satisfactory results of the mentocervical appearance and cervical extension function were obtained in 21 patients whose mentocervical and cervicomental angles were restored to normal. Conclusion Platysma scar flap transfer is an effective method to reconstruct mentocervical appearance and reduce mentocervical and cervicomental angles in patients with mentocervical cicatricial contracture deformity.

  • REPAIR OF CHRONIC OSTEOMYELITIS OF STERNUM AFTER THORACOTOMY WITH GREATER PECTORAL MUSCLE FLAP

    Objective To explore a surgical method for chronic osteomyel itis of sternum after thoracotomy. Methods From January 2006 to February 2009, 11 cases of chronic osteomyelitis after thoracotomy (2 cases of coronary bypass, 6 cases of mitral valve replacement, and 3 cases of ventricular defect repair) were admitted. Of them, there were 6 males and 5females, aged from 6 to 62 years (median 34 years), including 6 cases of simple osteomyelitis of sternum, 2 cases of osteomyelitis of sternum with suppurative infection of mediastinum, and 3 cases osteomyel itis of sternum with costal chondritis. Necrotic sternum were excised and defect was from 4 cm × 3 cm to 7 cm × 4 cm. Greater pectoral muscle flap was designed from 8 cm × 5 cm to 10 cm × 6 cm on one side and was transferred to defect. Negative drainage and sensitive antibiotics were administered after operation. Results Healing by first intention was achieved in 10 patients except 1 patient who had a few discharge at the drainage outlet and whose incision healed 1 week later. The follow up was from 3 to 10 months with an average of 6 months. The formed scars were flat with soft texture in 8 patients and moderately hypertrophy in 3 patients. The wounds healed without pain, relapse or abnormal function of donor upper limb. Conclusion Transplantation of greater pectoral muscle flap is an effective way to repair chronic osteomyelitis of sternum after thoracotomy.

  • RECONSTRUCTION OF SOFT TISSUE DEFECTS IN MAXILLOFACIAL REGION USING STERNAL HEAD OF STERNOCLEIDOMASTOID MYOCUTANEOUS FLAP

    Objective To evaluate the preliminary effect of using the sternal head of the sternocleidomastoid myocutaneous flap to reconstuct a defect in the maxillofacial region. Mathods From May 2004 to September 2006, 5 male patients aged 2334 underwent the reconstruction for the defect in the maxillofacial region by using the sternal head of the sternocleidomastoid myocutaneous flap. Their defects were caused by an infection of the face, an injection of medicine in the mother’s uterus or a scar or depressed abnormality left by an electric injury. The defects ranged in size from 5 cm×3 cm to 9 cm×6 cm. Results All the 5 sternocleidomastoid myocutaneous flaps survived, with a little necrosis of the epidermis because of the venous return disturbance, but 2-3 weeks after operation the necrosis healed spontaneously with just a little scar formation around the flap. One patient had weakness in the left shoulder after operation, which almost recovered 6 months after operation. The postoperative follow-up for 1-6 months revealed that 1 patient had a little fat and clumsy appearance in the flap pedicle, 1 patient had an obvious scar at the operation site, but the 2 patients still felt satisfaction. The other 3patients were satisfied with their good appearance at the operation sites. Conclusion The sternal head of the sternocleidomastoid myocutaneous flap can be designed with more flexibility compared with the entire sternocleidomastoid myocutaneous flap. It can provide an enough tissue mass for restoring the defect. The sternal head of the sternocleidomastoid myocutaneous flap is an ideal tissue flap for restoring defects in the maxillofacial region.

  • SURGICAL TREATMENT OF HEMANGIOMA AND VASCULAR MALFORMATION IN BODY SURFACE

    Objective To investigate the surgical treatment and curative effect of hemangioma and vascular malformation in body surface. Methods From May 2003 to December 2006, 145 patients with hemangioma or vascular malformation (81 males and 64 females, aging from 2 months to 40 years with median of 17 years) were treated with surgical therapy. The course of disease was from 2 months to 40 years. The locations were head and face in 85 cases, extremities in 34 casesand trunk in 26 cases. The size ranged from 1 cm × 1 cm to 27 cm × 24 cm. Wounds were sutured directly after lesions excision in 40 cases, were repaired with 3 cm × 2 cm-18 cm × 11 cm local flap transferring in 21 cases (donor site sutured directly in 18 and free skin grafted in 3) and with 5 cm × 3 cm-27 cm × 18 cm middle-thick skin graft in 84 cases (abdominal skin donor site sutured directly in 61, thigh skin donor site thin-partial-thickness grafted in 5 and skin in-situ regrafted in 18). Results The pathological results showed 38 cases of capillary hemangioma, 23 cases of venular malformation, 67 cases of venous malformation, 15 cases of arteriovenous malformation and 2 cases of lymphatic malformation. Six of 84 cases receiving free skin graft had partial skin necrosis; one case compl icating by skull exposure achieved heal ing after local fascial flap transferring and other 5 cases achieved heal ing by second intention after dressing changes. Other free skin graft survived. All the donor sites healed by first intention. All patients were followed up for 1-3 years. Recurrence occurred in 12 cases 6 months to 2 years after operation, including 4 cases of arteriovenous malformation, 7 cases of venous malformation and 1 case of venular malformation. They were cured after second operation. The others achieved good results with no recurrence. Conclusion Extensive and thorough excision was the effective way to cure hemangioma and vascular malformation in body surface. All cases should be followed up closely to deal with recurrence promptly.

  • Application of modified inferior pedicle technique with inverted T pattern for severe breast hypertrophy

    ObjectiveTo explore the effectiveness of modified inferior pedicle technique with inverted T pattern for severe breast hypertrophy.MethodsBetween January 2016 and May 2017, 15 patients of severe breast hypertrophy had undergone breast reduction using inferior pedicle technique with inverted T pattern combined with dermal suspension sling technique. The patients were 20 to 49 years old, with an average age of 31.6 years. Body mass index ranged from 24.9 to 32.5 kg/m2, with an average of 30.8 kg/m2. Among them, 11 cases had a history of childbearing. The degree of breast ptosis was rated as degree Ⅱ in 6 cases and degree Ⅲ in 9 cases. The unilateral breast reduced 615 g on average (range, 480-1 050 g).ResultsThe skin flap necrosis at the " T” trilateral junction occurred in 3 cases, and healed after dressing changes. The incisions of 12 cases healed and no fat liquefaction, hematoma, or seroma occurred. The sensation of nipple and areola declined at early period after operation in 2 cases, and gradually recovered. All patients were followed up 6-18 months (mean, 13 months). The shapes of bilateral breasts and the height and symmetry of nipple-areolar complex were good, and no obvious scar was found. The effectiveness was evaluated by surgeon and showed that there were 12 cases with satisfactory breast shape and 3 cases with unsatisfactory breast shape; 3 cases with obvious scare and 12 cases with insignificant scar; 13 cases with normal nipple sensation and 2 cases with hypoesthesia; 11 cases with symmetric nipples and 4 cases with asymmetric nipples. The effectiveness was evaluated by patients and showed that the satisfactory breast shape in 10 cases, relatively satisfactory breast shape in 4 cases, and unsatisfactory breast shape in 1 case; highly acceptable scar in 9 cases, moderately acceptable scar in 4 cases, and unacceptable scar in 2 cases; overall satisfactory in 10 cases, relatively satisfactory in 4 cases, and unsatisfactory in 1 case, with the overall satisfaction rate of 93.3% (14/15).ConclusionFor severe breast hypertrophy, the modified inferior pedicle technique with inverted T pattern can obtain satisfactory appearance and avoid the mastoptosis.
