Injection Necrosis of the Glabella: Protocol for Prevention and Treatment After Use of Dermal Fillers

DERMATOLOGIC SURGERY, Issue 2 2006
ADRIENNE S. GLAICH MD
BACKGROUND Injection of filler materials into the dermis is well tolerated with few mild and transient side effects. Injection necrosis is a rare but clinically important potential complication caused by interruption of the vascular supply to the area by compression, injury, and/or obstruction of the vessel(s). The glabella is a particular danger zone for injection necrosis regardless of the type of filler used. OBJECTIVE We recommend a protocol that may be used to help prevent and treat injection necrosis of the glabella after injection with dermal fillers. CONCLUSION Injection necrosis in the glabellar region may be prevented by a knowledge of the local anatomy and an understanding of its pathophysiology and treated by a suggested protocol. [source]

Lining the mouth floor with prelaminated fascio-mucosal free flaps: Clinical experience

MICROSURGERY, Issue 5 2002
D.D.S., L. Chiarini M.D.
Soft-tissue defects of the mouth floor need thin, foldable, and pliable tissues able to preserve local anatomy as well as chewing, phonation, and deglutition. The oral mucosa is made of a stratified, nonkeratinized, epithelium-secreting mucus, which lubricates the oral cavity and facilitates tongue movements. No flap exists that can reproduce the physiology of the oral mucosa better than the oral mucosa itself. Prefabrication of mucosal flaps may represent the best solution. Therefore, 10 consecutive cases of mouth floor cancer were treated with prelamination of the fascia antibrachialis with mucosal grafts obtained from the healthy cheek, and with subsequent transplantation 3 weeks later. A significant increase in mucosal graft surface was seen in all cases, with a mean size twice the original. All flaps healed uneventfully. Follow-up time ranged between 2,60 months (average, 26.6 months). Morphological and functional results were excellent. Tongue motility, speech intelligibility, and swallowing were reestablished in all treated cases. Mucosal prelamination of the forearm fascia is feasible and allows physiological reconstruction of oral cavity defects up to 6 × 4 cm. © 2002 Wiley Liss, Inc. MICROSURGERY 22:177,186 2002 [source]

Dosimetric evaluation and comparison of different RF exposure apparatuses used in human volunteer studies

BIOELECTROMAGNETICS, Issue 1 2008
Clémentine M. Boutry
Abstract The aim of this study was to provide the information necessary to enable the comparison of exposure conditions in different human volunteer studies published by the research groups at the Universities of Turku, Swinburne, and Zurich. The latter applied a setup optimized for human volunteer studies in the context of risk assessment while the first two applied a modified commercial mobile phone for which detailed dosimetric data were lacking. While the Zurich Setup exposed the entire cortex of the target hemisphere, the other two setups resulted in only very localized exposure of the upper cheek, and concentrated on a limited area of the middle temporal gyrus just above the ear. The resulting peak spatial SAR averaged over 1 g of the cortex was 0.19 W/kg of the Swinburne Setup, and 0.31 W/kg for the Turku Setup, compared to 1 W/kg for the Zurich Setup. The average exposure of the thalamus was 5% and 9% of the Zurich Setup results for the Swinburne and Turku Setups, respectively. In general, the phone-based setup results in only reasonably defined exposures in a very limited area around the maximum exposure; the exposure of the rest of the cortex was low, and may vary greatly as a function of the setup, position, and local anatomy. The analysis confirms the need for a carefully designed exposure setup that exposes the relevant brain areas to a well-defined level in human volunteer studies, and shows that studies can only be properly compared and replicated if sufficiently detailed dosimetric information is available.

Duplicated inferior vena cava and crossed renal ectopia with abdominal aortic aneurysm: Preoperative anatomic studies facilitate surgery

CLINICAL ANATOMY, Issue 4 2003
M. B. K. Shaw
Abstract Abdominal aortic aneurysm in association with duplication of the inferior vena cava and crossed renal ectopia is described for the first time. Preoperative imaging with computer-aided tomography provided good visualization of the local anatomy, allowing the surgical approach to be adapted for the best access to the surgical site. A retroperitoneal approach was successfully used for repair of the abdominal aortic aneurysm. Clin. Anat. 16:355,357, 2003. © 2003 Wiley-Liss, Inc. [source]
