The effect of reduction mammaplasty on the vertebral column: a radiologic study.

Some studies emphasized that anatomic mechanisms of vertebral aberrations could be associated with large breasts. The effect of mammaplasty operation on the vertebral column and body posture seems to be beneficial; in this trial, it was planned to investigate the objective radiologic effect of reduction mammaplasty on the posture of the vertebral column in a group of patients operated due to the large breasts. Thirty-four white women with large breasts were enrolled in this study.

Splitted posterior auricular muscle flap combined with traditional otoplasty.

Objective: This article presents a modified technique to split and reposition the posterior auricular muscle flap as an adjunct to traditional otoplasty.

Background: Although numerous techniques have been described for the correction of prominent ear deformity, there is still a continuing debate on which operative method achieves the best results. Recurrence of the deformity or the need for secondary revisions is still among the common problems.

Monitorization of asymmetric dimethylarginine (ADMA) levels in an experimental ischemia-reperfusion flap model: a preliminary report.

One of the most important endothelium-derived vasoactive mediators is nitric oxide (NO). Endothelial dysfunction by the loss of NO is a critical event during ischemia. Asymmetric dimethylarginine (ADMA) is a competitive inhibitor of NO synthase (NOS) that inhibits vascular endothelial NO production in concentrations found in pathophysiological conditions.

Short-term vasculoprotective effects of imatinib mesylate on intimal hyperplasia of arterial anastomosis: An experimental study using a rabbit model.

Background: Since the beginning of the 'microvascular era', the success rates of microvascular procedures have increased to more than 90% in most series. The main reason for failure, however, is the healing of microarterial anastomosis, which is dependent on the status of endothelial cells and affects the rate of arterial thrombosis. In 80% of arterial thrombosis cases, complications are primarily observed during the first 72 h after surgery.

Behavior of the different implant materials in acute infection and efficacy of antibiotherapy: experimental study in rats.

In this study, we propose a comparison of the behaviors of four different implant materials in case of acute infection: expanded polytetrafluoroethylene (e-PTFE), porous high density polyethylene (PHDPE), silicone, and autogenous cartilage tissue. The efficacy of prophylactic and therapeutic antibiotic therapies was also investigated in a rat model as four groups: group A, acute infection and no antibiotic therapy (n = 24); group B, acute infection and prophylactic antibiotic therapy (n = 24); group C, acute infection and therapeutic antibiotic therapy (n = 24); and control, no infection and no antibiotic therapy (n = 24). All materials with dimensions of approximately 1 x 1 cm(2) diameter were implanted separately under the dorsal skin of rats.

Interaction of botulinum toxin type A with local anesthetic agents: an experimental study with rabbits.

Injection of botulinum toxin is a painful procedure, limiting the number of patients treated. This study was designed to establish whether infiltration of local anesthetics plays a role in the effectiveness of botulinum toxin. For the study, 24 New Zealand white rabbits were divided into three groups.

Effects of surgical or chemical delaying procedures on the survival of proximal predicled venous island flaps: an experimental study in rats.

To increase the survival of proximally pedicled venous island flaps, which are known to be safe only when small, we used surgical and chemical delaying procedures both individually and in combination for 7, 14, and 21 days. Survival was 1% in those flaps designated as controls, in which there was neither surgical nor chemical delay. However, it was 3%, 31%, and 68% at 7, 14, and 21 days, respectively, when surgical delay was used and 16%, 56%, and 86%, at 7, 14, and 21 days, respectively, when chemical delay was used.

Prefabricated nasolabial flap for reconstruction of full-thickness distal nasal defects.

Background: The reconstruction of full-thickness nasal tip and alar defects is challenging owing to the distal nose's triple-layer structure: skin, cartilage, and mucosa.

Objective: In the reconstruction of wounds of the distal half of the nose involving the rim, the most important issue to be considered is to provide a good functional and an acceptable esthetic result. Various local and distant flaps have been described for this purpose.

What should be the treatment modality in giant cutaneous lipomas? Review of the literature and report of 4 cases.

We present three females (20, 39 and 58 years old) and one male patient (47 years old), admitted to our clinic with 3-20 years history of giant lipomas on periscapular (n = 2), posterior cervical (n = 1) and abdominal areas (n = 1), respectively. The sizes of the tumours ranged from 15 x 14 cm(2) to 35 x 25 cm(2) weighing 1900-12 350 g. In all cases, the diagnosis of the lesions was by physical examination and confirmed with computed tomography, magnetic resonance imaging and ultrasonography.
