The thoracodorsal artery musculocutaneous perforator flap: anatomic study and clinical significance / 中华整形外科杂志

<p><b>OBJECTIVE</b>To investigate the feasibility of clinical application of the thoracodorsal artery musculocutaneous perforator flap (TAMPF).</p><p><b>METHODS</b>(1) The morphosis and blood supply of TAP flap on 15 formalized adult cadavers(30 sides) were examined by microsurgery anatomy. (2) An imitative operation of the TAMP flap and latissimus dorsi flap on 1 formalized adult cadavers (2 sides) was conducted.</p><p><b>RESULTS</b>(1) A total of 102 musculocutaneous perforators larger than 0.5 mm were found in 16 specimens(32 sides). 56 perforators (55%) were originated from the medial branch and 46 (45%) originated from the lateral branch. The biggest perforator is (0.82 +/- 0.11) mm (0.68 - 1.08 mm). There was an average of 1.9 perforators (range, 1 - 3 perforators) of the medial branch and an average of 1.8 perforators (range, 1 - 3 perforators) of the lateral branch. Additionally, there were 24 perforators samller than 0.5 mm, and 76 perforators originated from intercostal artery and lumbar artery. (2) Musculocutaneous perforators over 0.5 mm were found only in proximity of the medial and lateral branches within a distance of 8.5 cm (6.4 cm - 9.2 cm) distal to the neurovascular hilus.</p><p><b>CONCLUSIONS</b>With the characteristics of constant position, large caliber, long pedicle, the thoracodorsal artery musculocutaneous perforator was suitable to be musclocutaneous perforator flaps and "fan-shaped" flaps.</p>

Heel deep tissue defects were repaired by perineal tendofascial flap conjoined with adipofascial flap / 中华整形外科杂志

<p><b>OBJECTIVE</b>To explore a new method and estimate its outcome to repair deep heel tissue injuries with local tissue flap.</p><p><b>METHODS</b>At lower cnemis, a fat fascial flap combined with perineal tendofascial flap were designed and elevated between the lateral malleolars blank, the largest area is 6 cm x 13 cm, which were transplanted to cover naked calcaneal tendon and calcaneal bone, full-thickness free skin graft or middle-thickness free skin graft were grafted on flap.</p><p><b>RESULTS</b>6 patients suffered from heel tissue defects had been treated from January 2004 to November 2005. The smallest area was 3.5 cm x 4.0 cm and the largest was 4 cm x 6 cm. All fascial flaps and free skin grafts were successfully survived after operations. All patients were followed up 3-23 months, the operation areas were healed, the functions and configurations were satisfied.</p><p><b>CONCLUSIONS</b>Perineal tendofascial flap conjoined with adipofasical flap and free skin graft are used to repair heel deep tissue defects, which is a handy, dependable way for repairing of the small tissue defects of the lower third of leg and heel.</p>

Nasal reconstruction with the modified expanded forehead skin flap / 中华整形外科杂志

<p><b>OBJECTIVE</b>To investigate the effect of the modified expanded forehead skin flap in nasal reconstruction.</p><p><b>METHODS</b>According to flap design, the frontal arteries that were not selected as the pedicle were ligated in order to enhance expansion and delay effects. Besides the middle forehead skin flap for nasal reconstruction, the expanded transversal forehead flap was employed with its donor site sutured directly, resulting in inconspicuous scar. This method was used for 11 cases of nasal reconstruction.</p><p><b>RESULTS</b>All the flaps survived. Postoperative follow up for 6 months to 8 years and 4 months showed satisfactory results with good appearance and function.</p><p><b>CONCLUSIONS</b>The method of modulating the blood supply to the flap and selecting the upper area of the forehead for the flap is an effective modification for nasal reconstruction.</p>
