A new, readily accessed and low-cost, device for treating depressed ping pong fractures non-surgically: Technical note.

Objective: The aim of this paper is to describe a low-cost and readily accessed Manual Aspiration Reduction System (MARS) for use treating ping-pong fractures in three patients.

Methods: The MARS is composed of a pediatric anesthesia mask, part of a macro dripper, a 3-way stopcock, and two 60-ml syringes. Prior to its use in our patient, the system was tested on five adult volunteers to maximum negative pressure, and none reported pain during the procedure or experienced any other complication.

A new, low-cost device to treat depressed "ping-pong" fractures non-surgically: technical note.

Objective: The aim of this paper is to describe a low-cost and readily accessed Manual Aspiration Reduction System (MARS) for use treating neonatal ping-pong fractures.

Methods: The MARS is composed of a pediatric anesthesia mask, part of a macro dripper, a 3-way stopcock, and two 60-ml syringes. Prior to its use in our patient, the system was tested on five adult volunteers to maximum negative pressure, and none reported pain during the procedure or experienced any other complication.

Three-dimensional imaging as a teaching method in anterior circulation aneurysm surgery.

Objective: Our objective is to present and asses the utility of three-dimensional (3D) intraoperative imaging as a teaching method for anterior circulation aneurysm surgery.

Methods: The senior author's experience in anterior circulation aneurysm surgery during a 28-month period was documented and processed as 3D images and compared with two-dimensional (2D) images. Both 2D and 3D sets of images were created, and, along with a specially designed questionnaire, 30 physicians (15 experienced cerebrovascular surgeons and 15 neurosurgical trainees) were asked to answer the query and state the advantages and disadvantages of both methods.

Soft tissue assessment in midface advancement: the use of regional flaps to enhance facial projection.

Classically, soft tissue repair when indicated is done before or after the skeletal mobilization especially in those cases that present midface deficiency with severe midline soft tissue restriction by scars or congenital affectation. The distraction osteogenesis method has contributed to improve substantially this problem elongating bones, muscles, and ligaments, but some situations need specific and more precise reconstruction of the subunits to gain in aesthetics. The labial-columella junction, the tip of the nose, and the more projecting point of the cheeks are one of these exigent anatomic areas, where only sophisticated reconstruction by flaps can improve facial proportions and projections.
