M oday, Sptem er 6, 2016 study, the authors introduce the utilization of alar pinning with the external halo distractor for maxillary advancement, in place of an oral splint. Fixation sites within the alar crease allow for maxillary advancement while minimizing the visibility of pin site scars. They also eliminate the need for a custom-made oral splint, which prevents the patient from using the...

Unilateral cleft lip nasal deformity is characterized by prominent asymmetry resulting from distorted and displaced structures. Primary correction of the nasal deformity at the same time of lip repair has gained popularity, aiming at early restoration of the symmetry by lifting the alar cartilage and lengthening the columella on the cleft side. Postoperative relapse is a frequent finding due to...

Background In the human ear and nose, cartilage plays a key role in establishing its form and function. Interestingly, there is a noticeable paucity on biochemical, structural, and mechanical studies focused on facial cartilage. Such studies are needed to provide elementary knowledge that is fundamental to tissue engineering of cartilage. Therefore, in this study, a comparison is made of the bi...

Introduction: Rhinoplasty is one of the most common surgical procedures performed among Iranians. An important issue to be considered by nasal surgeons is anatomical variations between different ethnic groups. Working on Iranians with the existing ethnic variety encourages the need for an analysis of this particular population.   Materials and Methods: The present cross-...

The expression of the Nkx2.2 gene is involved in the organization of the alar-basal boundary in the forebrain of vertebrates. Its expression in different diencephalic and telencephalic regions, helped to define distinct progenitor domains in mouse and chick. Here we investigated the pattern of Nkx2.2 protein distribution throughout the development of the forebrain of the anuran amphibian, Xenop...

BACKGROUND Lower lateral crural deformities are common problems in rhinoplasty. The shape and position of the lower lateral crura directly influence the alar contour and external valve function. This study reviews an extensive experience with the lower lateral crural turnover flap, which represents a versatile and reproducible technique for correction of lower lateral crural deformities and imp...

BACKGROUND The ala of the nose is vascularized by a dense net of perforators originating from the lateral nasal artery or the angular artery. These vessels reach the ala in a cascade fashion from the alar groove/lateral nasal wall. Based on these vessels, a V/Y flap can be dissected with a wide range of mobility. MATERIALS AND METHODS Nineteen patients underwent reconstruction of the nose by ...
