Résumé
Objective To search for a treatment approach for scalp avulsion injury based on the clinical experiences and review of literature.Methods Twenty-six consecutive scalp avulsion cases were involved in the study:15 cases were complete scalp avulsion (5 including forehead skin) and 11 cases were partial scalp avulsion.Cranial bones exposure occurred in 16 cases,11 of which had a size over 4 × 4 cm2.The treatment methods were various:11 cases with microsurgical replantation,9 cases with skin grafting,4 cases with secondary skin grafting followed by multiple drilling of the calvarium,1 case with local flap,and 1 case with free flap.According to the clinical cases and literature reviews,authors tried to search for an optimal protocol.Results Patients with microsurgical replantation achieved the best recovery including hair growth.In case of not qualified or fail to microsurgical replantation,skin graft could be considered as an alterative step,whereas the result of it was no hair growth and usually scar healing.In summary,14 different clinical conditions followed with 10 surgical techniques were concluded in a route chart.Conclusions To achieve the optimal outcomes of scalp avulsion injury,proper techniques should be chosen according to the treatment protocols.
Résumé
Objective To search for a good solution for aesthetic beard reconstruction and to explore the effect of the single-hair grafting in beard reconstruction. Methods Under the local anesthesia, a scalp strip (length range from 5～7 cm, width range from 1.0～1.5 cm) was harvested from the back of the head and then was divided into a series of single-hair micrografts. After the slits were made, the grafts were implanted into the holes, parallel to the original beard directions. The donor sites were directly closed. With this method, 18 sparse beard patients and 3 patients with upper lip scars were treated. Results The grafted hairs grew nearly in the direction of normal beard, which achieved 90 %～95 % survival in recipient areas. The patients were satisfied with the results, in which 19 cases received only 1 operation and 2 cases received another repeated operation. Conclusion Beard reconstruction by single-hair grafting technique is a good, safe and effective method.
Résumé
Objective To investigate the significance of using 2-dimonsional ultrasonography and color Doppler ultrasonography in the diagnosis of the complications of augmentation mammoplasty. Methods 21 cases were diagnosed by the 7.0～11.0 MHz high-frequency 2-dimonsional ultrasonography and color Dopplar ultrasonography, which were proved by the second operation. Results There were characteristic 2-dimonsional voice pictures in the implants folding, moving, oozing, and sclerosis of membrane, and the tissues around the implants had more or less color blood picture and Dopplar frequency expression. Conclusion Ultrasonography has great diagnostic value and clinical significance in the detection of complications after augmentation mammoplasty.
