Facial nerve variations and it's clinical significance in facial surgery

Descripción: Anatomy and variations of the facial nerve were studied in detail by the authors. Data was obtained from 800 facial nerve / branches dissection (HemiFace). Marked intraparotid, extraparotid, and muscle innervation pattern variations were found. Anatomy of the facial nerve is not constant, and considerable variable patterns exist. Facial surgeons should be familiar with the variable patterns, in order to avoid nerve injury, and with the various methods of handling nerve injuries.

History of botulinum neurotoxin type A

Descripción: Identified as a cause of food poisoning in the late nineteenth century and first used in humans to treat strabismus, botulinum neurotoxin (BoNT) has since become one of the most requested agents used worldwide in facial rejuvenation to enhance and reshape the aesthetic contours of the face. Indications approved by the Food and Drug Administration (FDA) include a host of therapeutic disorders characterized by muscle hyperactivity, as well as hyperdynamic rhytides in the upper face. Moreover, offlabel use has expanded and evolved to include increasingly complicated indications, from the treatment of simple rhytides to the sculpting and moulding of the face, creating a more pleasant and youthful appearance. Used therapeutically in humans for nearly 30 years, BoNTs carry an impressive record of efficacy and safety when used appropriately by experienced injectors.

Medical face lifting: regeneración de los tejidos faciales

Descripción: A nivel facial, el envejecimiento determina una reducción de volúmenes y de consistencia de los tejidos, lo cual determina una caída (ptosis) de éstos por acción de la gravedad, y la consiguiente aparición de alteraciones estéticas. El tejido óseo del cráneo involuciona disminuyendo su volumen. De este modo se reducen las superficies de apoyo de los tejidos blandos que revisten el hueso, con el consiguiente “relativo” desequilibrio entre contenido y continente, lo cual determina descolgamiento de aquellos. El tejido muscular también involuciona, aunque este proceso no es el más determinante. El tejido adiposo pierde su consistencia y su volumen con un efecto de vaciado del rostro; se produce un deslizamiento hacia abajo y adelante del tejido cutáneo que está por encima de la zona afectada. Finalmente también la dermis pierde su turgencia, sea por pérdida de agua o por desestructuración de la matriz intercelular.

Survey of transumbilical breast augmentation (Tuba)

Descripción: The transumbilical breast augmentation (TUBA) has been utilized for at least the past 17 years as an alternative to other approaches for augmentation. There are essentially few articles that have included the possible risks and complications and their rate. This study, using a form, was done to collect as many cases as possible to determine the type of the TUBA procedure utilized and the rate of some of the possible complications. A total of 5,073 cases were reported and the statistics evaluated.

The Heinous Practice of “Envying, Tripping or Traps” Among Colleagues

Descripción: The heinous practice of “envying, tripping or traps”, among colleagues is becoming more and more common, nowadays, especially against cosmetic surgeons. This has been the practice, not only in the past, whereby most of our teachers regarded cosmetic surgery as “unnecessary”.

Archives of Facial Plastic Surgery

Descripción: A double triangular flap, or hatchet flap, with a partial cutaneous pedicle, has great versatility for facial reconstruction, yet there has been little published discussion regarding the potential applications and/or modifications of the flap. A total of 483 cutaneous malignant neoplasms have been excised and repaired by the senior author (C.C.M.) using a modified bilateral hatchet flap; 366 of the neoplasms were located in the head and neck region. The flap has been used to reconstruct defects in the scalp, eyebrow, lower eyelid, nasal tip, cheek, chin, arms, and torso. The authors report no cases of flap loss. The design of the flap and modification, used by the authors, has been discussed in detail, along with a description of 4 representative cases.

Descripción: 3 Cases of Dissecting Cellulitis of the Scalp Treated With Adalimumab. Control of Inflammation Within Residual Structural Disease.
Background: Dissecting cellulitis of the scalp (DCS) is a chronic inflammatory disease of scalp hair follicles manifesting as multiple painful nodules and abscesses that interconnect via sinus tracts. The disease tends to run a progressive course that eventually results in scarring alopecia. The condition is thought to represent a follicular occlusion disorder. Sebaceous and keratinous material within dilated pilosebaceous units accumulates until follicles burst, with subsequent neutrophilic inflammatory reaction and abscess formation. Treatment remains unsatisfactory. While oral antibiotics, intralesional corticosteroids, isotretinoin, or dapsone are insufficient, in this case series the inflammation responsible for scarifying tissue destruction was directly targeted by means of the tumor necrosis factor antagonist adalimumab.

Aesthetic Surgery Journal - March 2010

Descripción: Separating the Helix From the Antihelix A New Concept in Prominent Ear Correction. Background: For over a century, various otoplasty techniques for correction of the prominent ear have been attempted. Nevertheless, cartilage memory strength, mainly in the thick cartilage (and consequently the recurrence of the prominence), still remains a problem. An additional difficulty relates to the antihelix irregularities caused by attempts to weaken the cartilage spring, which are timeconsuming and in some cases lead to an innaturallooking result.
