BACKGROUND Posttraumatic and postoperative defects of columella and the tip of the nose are difficult to reconstruct. There are several operative methods described in the literature, and many of them are step-by-step procedures with long duration. The aim of this study was to present one-step procedure for reconstruction of the columella and the tip of the nose with island-shaped arterial foreh...

BACKGROUND The ala of the nose, with its particular texture and characteristics, poses both aesthetically and functionally intriguing challenges and is rather problematic regarding choices for reconstructive methods. Both flaps and grafts have been used to restore natural structure of nasal ala. The present study summarizes a ten-year experience of reconstructive surgery using small composite...

DESCRIPTION The patient is a 24-year-old woman who presents for a cosmetic rhinoplasty for improvement of her wide alar base.

IMPORTANCE "Large" nasal defects are typically classified as larger than 1.5 cm. Within that group, however, there is a subset of patients with smaller nasal defects (1.5-2.5 cm) who are treated differently. This study examines the different methods that we have used in the reconstruction of such "intermediate-size" nasal defects. OBJECTIVE To review the treatment and outcomes of patients who...

Pax7 is a member of the highly conserved Pax gene family that is expressed in restricted zones of the central nervous system (CNS) during development, being involved in early brain regionalization and the maintenance of the regional identity. Using sensitive immunohistochemical techniques we have analyzed the spatiotemporal pattern of Pax7 expression in the brain of the anuran amphibian Xenopus...

BACKGROUND Lateral crural strut graft has been used in rhinoplasty to correct deformities such as bulbous nasal tip, lateral crus malposition, alar retraction, collapsed external valve, lateral crus concavity, and alar deformity after domal suture. Despite its widespread use, the lateral crural strut graft has not been the subject of studies that show its benefits objectively and statistically....
