The nasolabial cyst is a rare, usually unilateral lesion arising in the soft tissues adjacent to the alveolar process of the anterior maxilla, above the apices of frontal teeth and below the alar base. The typical clinical features of nasolabial cysts are: swelling between the upper lip and nasal aperture caused by a smooth and fluctuant, well defined space-occupying lesion, elevation of the na...

Recently, injectable dermal fillers have become important alternatives to surgical procedures for the correction of facial wrinkles. Bovine collagen is the first approved material for filler injection, and several studies have shown its efficacy. However, the risk of developing an allergic reaction and xenogenic transmission of bovine spongiform encephalopathy remain among its disadvantages. In...

Free and pedicled flaps are frequently used in reconstruction of the lower two-thirds of the face. For these reconstructions, the submandibular facial vessels are extensively used as a receptor site. In this anatomic study, we investigate if the facial vessels in the nasolabial fold can be used as a receptor site as well. In 13 human cadavers, the facial artery and vein were dissected in the na...

The nasolabial cyst or Klestadt cyst is a relatively uncommon nonodontogenic cyst that develops in the nasal alar region; it has uncertain pathogenesis. This lesion has slow growth and variable dimensions and is characterized clinically by a floating tumefaction in the nasolabial fold area around the bridge of the nose, causing an elevation of the upper lip and relative facial asymmetry. Diagno...

Twenty normal individuals were submitted to facial nerve electroneurography using different techniques in order to determine the most accurate to obtain the latencies and amplitudes of the compound muscle action potentials (CMAP) of the facial muscles. First of all it was determined in which muscle or muscle group highest amplitude CMAP could be recorded with the lowest variability between side...

The goal of facial rejuvenation surgery is to provide a youthful contour to an ageing face. Facelift surgery has gone through a variety of modifications during the past 20 years. Initially, only skin lifts were performed, then modification of the submuscular aponeurotic system (SMAS) and platysma surgery. This endangered the facial nerve and parotid gland. Subsequently, adjunctive procedures we...

Lymphoma is a cancer of the lymphocytes which leads to solid tumors in the lymphoid organs involving lymph nodes, spleen, liver, bone marrow and skin. Primary cutaneous lymphoma, a rare subtype of non-Hodgkin's lymphoma, can be classified as cutaneous T-cell or cutaneous B-cell lymphoma. These tumors are mostly T-cell origin and mainly locate on trunk, extremities and scalp or forehead. In this...

Background: With aging, the facial folds, grooves, and sagging tissue become more prominent. It is haracterized by loss of the collagen mass in the dermis and an increased array of elastin whirls in the deeper dermis. The aim of this study was to determine whether correction of nasolabial folds could be achieved using an allogeneic collagen product. Methods: Nine healthy volunteers participated...

Introduction Autologous plasma-rich platelet (PRP) is a human platelet concentrated product which is in low volume of plasma. Using PRP in rejuvenation and resolution of some cosmetic problems has been already popular in many countries and also in Iran. As no study performed in this field in Iran and regarding the high prevalence of using PRP in society with no validate references in the case ...
