Gluteal implants offer a good way not only to correct hypoplasias, but also to remodel and give rounded shape to buttocks, achieving beauty and sensuality. However, until recently, only a few surgeons have used this procedure. An intramuscular introduction of the implants may be a good means of reaching this goal, but because the undermining is performed without direct view, difficulties may occur in obtaining a symmetric and safe plane, and this can lead to unpleasant results. This report presents an intramuscular method based on geometry, in which three points (X, Y, and Z) and a line (G) in the pelvis define the plane in which the dissection must be performed, allowing more precise and safe undermining. From 1986 to 2003, 746 patients underwent surgery using this technique, achieving good results. This technique has proved to be a safe and reproducible way of performing augmentation gluteoplasty.

This pictorial review describes in detail the examination technique used to study the neonatal brain via the mastoid fontanelle and offers a panoramic view of the anatomical structures that can be identified in each US slice. The brain lesions are grouped as congenital malformations, haemorrhage, cerebellar lesions and sinus venous thrombosis. In each section, the additional information obtained through the mastoid fontanelle is provided.

Gluteal augmentation with silicone implants has gained popularity in the last decade. Despite this, no previous studies have examined multisurgeon experiences with this procedure to determine complication rates or surgeon technical preferences. The authors present data from a survey sent to experienced gluteal augmentation surgeons. Advances in technique and implant options are needed to improve complication rates experienced with this procedure.
