Prelaminated Supraclavicular Island Flap for Total Ear Reconstruction: A New Technique.

Major ear reconstruction has progressed over the past years with the emergence of new techniques directed mainly to patients without available or usable local skin. However, microsurgical transfer requires specific training and eligible patients. The authors report a successful ear reconstruction with a prelaminated supraclavicular island flap in 3 stages, which may be a valuable resource for selected patients or when microsurgery is not available.

The positive effect of Botulinum toxin type A on the viability of random flap in tobacco exposed in rats.

Purpose:: To evaluate the effect of Botulinum Toxin A in different time of tobacco exposure.

Methods:: 60 male, Wistar rats were divided into two tobacco exposure groups: a 2- month or a 4-month regimen. After this period, these two groups were subdivided as two: saline solution(SS) or botulinum toxin A(Bonta), at the time of the surgery.

A clinical experience of the supraclavicular flap used to reconstruct head and neck defects in late-stage cancer patients.

The supraclavicular island flap has been widely used in head and neck reconstruction, providing an alternative to the traditional techniques like regional or free flaps, mainly because of its thin skin island tissue and reliable vascularity. Head and neck patients who require large reconstructions usually present poor clinical and healing conditions. An early experience using this flap for late-stage head and neck tumour treatment is reported.

Biomechanical analysis of sutures used for mesh fixation in the donor area after removal of the rectus abdominis muscle.

Background: The use of synthetic mesh for abdominal wall closure after removal of the rectus abdominis is established but not standardised. This study compares two forms of mesh fixation: a simple suture, which fixes the mesh to the edges of the defect on the anterior rectus abdominis fascia; and total fixation, which incorporates the fasciae of the internal oblique, external oblique and transverse muscles in the suture, anchoring the mesh in the position of the removed muscle.

Method: A total of 16 fresh cadavers were dissected.

Complications after polymethylmethacrylate injections: report of 32 cases.

Background: During the past 15 years, polymethylmethacrylate has been used as a synthetic permanent filler for soft-tissue augmentation.

Methods: This article reports 32 cases of complications seen at Hospital das Clínicas, Faculty of Medicine, University of São Paulo, for procedures performed elsewhere.

Results: The average age of the patients was 43.
