We describe a novel procedure for an anatomically-based face lift to correct vertical vectors in the ageing face. It has the advantage of surgical simplicity, minimal tissue removal and minimal risk. It provides an effective readjustment of cheek volume and correction of periorbital hollowness. Natural facial expression is preserved largely because there is no change in the position of the lateral canthus. The cheek is mobilised subperiosteally through a blepharoplasty incision. A second dissection is made via a short temporal incision, to join the infraorbital dissection. A Hagedorn needle is then inserted through a point inferior to the lateral canthus and in line horizontally with the nasal ala. It is passed to the orbital incision, charged with a loop of suture material, and pulled down again to the cheek incision, from where it is pushed back to the orbit to suspend the cheek. The upper border of orbicularis oculi is fixed firmly to the temporalis aponeurosis at the level of the temporal incision. We now frequently use an Endotine Midface device for fixation. Of the first 150 patients, results were excellent or good in 145. This represents a revival of the subperiosteal mask lift, and abandons the use of endoscopic techniques. In spite of its simplicity, the operation involves subperiosteal dissection as well as delicate eyelid surgery that necessitate plastic surgical skill. 相似文献

Computed tomography (CT) was performed in 42 patients with 49 clinically suspected tears of the posterior tibial tendon. Twenty-eight of the 49 suspected tears were subsequently surgically explored and repaired. Three patterns of tendon abnormalities were recognized on CT scans: type I-intact, hypertrophied, heterogeneous tendon; type II-attenuated tendon; and type III-absence of a portion of a tendon. Types I and II correlated with partial rupture seen during surgery, and type III correlated with complete rupture of the tendon. CT findings were accurate in 96% of the patients who underwent surgery. In four cases (14%), tendon rupture was seen on CT scans, but the extent of the injury was underestimated and the rupture was misclassified. Reactive periostitis of the distal tibia was seen in 71% of diseased tendons and may represent an important factor in the diagnosis of tendon rupture. 相似文献

The authors report the case of a 59-year-old woman with a complex cardiac lesion consisting of degenerative major mitral insufficiency masking partial abnormal pulmonary venous return. These cardiac abnormalities fell within a context of genetic disease since the patient had Turner's syndrome, confirmed at the age of 58 by a 45 x 0 karyotype. They detail the originality of the clinical manifestations of partial abnormal pulmonary venous return and review the literature concerning cardiac malformations in Turner's syndrome. 相似文献
