Through this critical evaluation, the reader will be able to identify when distraction techniques are appropriate, when traditional techniques are more favorable, and what the future of distraction osteogenesis is.Background The subfascial compartment (deep to the deep fascia) in extremity lymphedema has not been evaluated. This study investigated the volumetric differences between the suprafascial and subfascial compartments of patients with unilateral lower extremity lymphedema. Cenicriviroc nmr Methods Thirty-two female patients with unilateral lower extremity lymphedema were enrolled, with eight patients in each of Cheng lymphedema grades I to IV. The volumes of the suprafascial and subfascial compartments were calculated after manually drawing the region of interest on computed tomographic images. The volumetric differences and their ratios in the suprafascial and subfascial compartments between each patient's bilateral limbs were compared. Results The volume of the lymphedematous limbs (9647 ml) was significantly greater than the volume of unaffected limbs (6906 ml), with a median volumetric difference of 2097 ml (30.6 percent) (p less then 0.01). The median suprafascial compartment volumetric difference was 1887 ml (56.6 percent) and the subfascial compartment volumetric difference was 208 ml (4.7 percent) (p less then 0.01). The median volumetric difference ratio of the thigh and lower leg was 24.6 percent and 40.6 percent, respectively. The median volumetric differences in Cheng lymphedema grades I to IV were 1012, 1787, 2434, and 4107 ml, respectively, which were statistically significant among the four Cheng lymphedema grades using the Kruskal-Wallis test (p less then 0.01). Conclusions The volumetric differences in the lymphedematous limb were statistically significantly greater than in the unaffected limb, including both suprafascial and subfascial compartments. The volumetric differences are consistent with the Cheng lymphedema grading system as a reliable indicator of unilateral extremity lymphedema.

This study set out to determine the effects of facial feminization surgery on quality-of-life outcomes for gender-diverse patients. Methods A prospective, international, multicenter, cohort study with adult gender-diverse patients with gender dysphoria was undertaken. Facial feminization outcome score was calculated preoperatively and postoperatively (1-week to 1-month and >6 months). Photogrammetric cephalometries were measured at the same time points. Self-perceived preoperative masculinity and femininity were recorded. Externally rated gender appearance (scale of 1 to 5, with 1 being most feminine) and general aesthetics (scale of 1 to 10, with 10 being very good) for 10 facial feminization surgery patients were compared with those of five cisgender controls. Univariate linear regression analyses were used to predict outcomes from facial feminization surgery. Results Sixty-six consecutive patients were enrolled. Patients noted that their brows, jaws, and chins were the most masculine aspects of their faces (54.5 percent, 33.3 percent, and 30.3 percent, respectively). Median facial feminization outcome score increased from 47.2 preoperatively to 80.6 at 6 months or more postoperatively (p less then 0.0001). Mean satisfaction was excellent (3.0 at both 1-month and ≥6-month follow-up; p = 0.46). Cephalometric values were significantly more feminine after surgery. Gender appearance was feminine to very feminine (1.83 ± 0.96) and general aesthetics were good (6.09 ± 2.01) but different from those of cisgender women controls (1.25 ± 0.49 and 7.63 ± 1.82, respectively; p less then 0.001 for each). Conclusion Facial feminization achieved improved quality of life, feminized cephalometries, feminine gender appearance, good overall aesthetics, and high satisfaction that were present at 1 month and stable at more than 6 months. Clinical question/level of evidence Therapeutic, IV.Background Midface hypoplasia dramatically affects the normative facial cascade. Simultaneous Le Fort III and Le Fort I procedures (Le Fort III/I) provide a powerful tool for achieving significant midface advancement. This study presents the authors' approach for addressing midface hypoplasia in the setting of class III malocclusion using Le Fort III/I advancement. Methods This was an institutional review board-approved retrospective review of patients who underwent Le Fort III/I advancement at the authors' institution from 2009 to 2019. Demographic, surgical, and postoperative data were recorded. The authors' operative technique and surgical pearls are described. Results Twenty-five patients met inclusion criteria, 15 male patients (60 percent) and 10 female patients (40 percent). Patient age ranged from 14.9 to 21.6 years. Diagnoses included Crouzon syndrome, nonsyndromic developmental skeletal dysplasia, cleft lip/palate, Klippel-Feil syndrome, Apert syndrome, Van den Ende-Gupta syndrome, and Pfeiffer syndrome. Le Fort III advancements averaged 6.18 ± 1.38 mm and Le Fort I advancements averaged 6.70 ± 2.48 mm. Thirteen patients underwent simultaneous bilateral sagittal split osteotomy with average movement of 5.85 ± 1.21 mm. Average follow-up was 1.3 ± 1.0 years. One patient experienced intraoperative cerebrospinal fluid leak that resolved with expectant management. Three patients experienced major complications (12 percent) postoperatively necessitating repeated orthognathic operations. Ten patients experienced minor complications (40 percent). Average length of stay was 10 days, with all patients achieving improvement of their facial profile. Conclusions The authors' experience reaffirms the relative safety of simultaneous Le Fort III/I advancement. This technique should be considered in select patients with global midface retrusion and class III malocclusion. Clinical question/level of evidence Therapeutic, IV.Background This study compared the effectiveness of injectable collagenase clostridium histolyticum and percutaneous needle fasciotomy in the treatment of Dupuytren's contracture. Methods Patients with a total passive extension deficit of 30 degrees or more in a single digital ray were enrolled and assigned randomly to receive either collagenase clostridium histolyticum injections or percutaneous needle fasciotomy. Preoperative severity of proximal interphalangeal joint contracture for Dupuytren's disease was classified according to the British Society for Surgery of the Hand as less than 30 degrees (stage I) or 30 degrees or more (stage II). Results Of the 70 patients enrolled, 36 patients with 46 joints received collagenase clostridium histolyticum injections and 34 patients with 48 joints received percutaneous needle fasciotomy. At day 30, successful corrections were obtained in only 50 percent of the injection group and 67 percent of the fasciotomy group for stage II proximal interphalangeal joints. Recurrences were frequent among patients with stage II joint contractures.
