BACKGROUND Alar rim deformities such as retraction, notching, collapse, and asymmetry are common problems in rhinoplasty patients. Although alar rim deformities may be improved through rhinoplasty, this area is prone to late changes because of scarring of the soft triangles and a paucity of native structural support. The purpose of this study was to analyze the effect of alar contour grafts on ...

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...

OBJECTIVE To describe the experience of a single department using uncovered subcutaneous hinge flaps to repair the nasal portion and adjacent facial subunits of defects after skin tumor excision. DESIGN Case series of 16 patients needing reconstruction for lesions of the alar subunit with 1 or more adjacent facial subunits after Mohs surgery for cutaneous malignant neoplasms. RESULTS All fl...

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 ...
