BACKGROUND AND PURPOSE Evaluation of alar traumatic injuries by using MR imaging is frequently performed. This study investigates the variability of morphology and signal intensity of alar ligaments in healthy volunteers so that pathology can be more accurately defined. MATERIALS AND METHODS Fifty healthy volunteers were examined on a 1.5T MR imaging scanner with 2-mm PD-weighted sequences in...

Activation of dihydrogen by masked dialumenes (Al=Al doubly bonded species) is reported. Reactions of barrelene-type dialumanes, which have the reactivity as masked equivalents of 1,2-diaryldialumenes ArAl=AlAr, with H2 afforded dihydroalumanes ArAlH2 at room temperature (Ar: bulky aryl groups). These dihydroalumanes form hydrogen-bridged dimers [ArHAl(μ-H)]2 in the crystalline state, while a m...

BACKGROUND Reconstruction of nasal alar defects is difficult because of the complex anatomy of the region. A frequent challenge in this area is repair of small cutaneous defects involving the lateral nasal supratip and the superior alar groove. OBSERVATIONS An oblique advancement flap that uses laxity from the nasal sidewall is described. Its benefits and limitations are compared with those o...

This technical report describes a simple and innovative surgical technique for supra-alar sidewall region constriction and supra-alar crease attenuation by cinching technique through intraoral approach.

Injection of synthetic fillers for soft tissue augmentation is increasing over the last decade. One of the most common materials used is hyaluronic acid (HA) that is safe and temporary filler for soft tissue augmentation. We present a case of 54-year-old female who experienced vascular occlusion and nasal alar necrosis following HA injection to the nasolabial folds. She suffered from pain, necr...

i ntroduction: due to the increase in le fort surgeries and its effect on nose widening, it seems necessary to use an alternative method without this effect. the present research examined the effect of alar release on interalar changes in le fort i osteotomy. m at erials and methods: the study population included patients admitted to bou-ali hospital in 2012-2013 undergoing le fort i osteotomy....

It is generally believed that the spinal cord and hindbrain consist of a motor basal plate and a sensory alar plate. We now have molecular markers for these territories. The relationship of migrating branchiomotor neurons to molecularly defined alar and basal domains was examined in the chicken embryo by mapping the expression of cadherin-7 and cadherin-6B, in comparison to genetic markers for ...

Although the cartilaginous autografts are one of the tissues more utilized in nasal surgery, a comparative study does not exist to determine which are better options and their precise indications. It is for this reason that a histopathologic analysis was carried out comparing the characteristics and properties of the four principal cartilages that are utilized in aesthetic functional surgery of...

Almost half a century ago, Tennison (1) proposed a triangular flap cleft lip repair that for the first time preserved the existing lip elements and permitted the creation of a normal Cupid’s bow. Brauer (2) and Randall (3) are better known for improving this original concept, but Millard (4) credits Marcks for popularizing Tennison’s method while developing his own Z-plasty modification. Trevas...
