The Effect of Orthognathic Surgery on Soft-Tissue Facial Asymmetry: A Longitudinal Three-Dimensional Analysis.

In modern orthognathic surgery, the functional results cannot disregard a good aesthetic outcome. In this study, a stereophotogrammetric longitudinal analysis of the symmetry of facial thirds was performed in 18 patients affected by Class III skeletal malocclusion, with clinical asymmetry, treated with a bimaxillary osteotomy. Their 3-dimensional facial images were acquired in the preoperative phase and 6, 12, and 24 months after surgery, and compared to those obtained in a control group of 23 subjects with Class I skeletal occlusion, without clinical asymmetry and no history of traumas or alterations at the maxillo-facial area.

International validation of the prognostic value of subclassification for AJCC stage pT3 upper tract urothelial carcinoma of the renal pelvis.

Unlabelled: What's known on the subject? and What does the study add? Tumour stage is a powerful predictor of clinical outcomes and the most important factor driving clinical decision-making after radical nephroureterectomy (RNU) in upper tract urothelial carcinoma (UTUC). It has been suggested that renal pelvic pT3 subclassification into microscopic infiltration of the renal parenchyma (pT3a) versus macroscopic infiltration or invasion of peripelvic adipose tissue (pT3b) has strong prognostic value. This is an external validation study of the prognostic value of pT3 subclassification of renal pelvic UTUC in a large international cohort of patients treated with RNU.
