Reconstructing the nose, especially the alar-facial groove, is difficult because of its 3-dimensional structural characteristics. We report the case of a 33-year-old man with a history of crush injury to the nose 15 years previously. We performed reconstruction because of scar contracture formation in the left alar-facial groove (Fig. 1). This study was reviewed and approved by the Ethics Revie...

he nasal valve is the narrowest region of the nasal passage, nd the main, flow-limiting segment of the nasal cavity.1,2 ariations in the size and shape of the nasal cavity affect he rate and pattern of airflow and influence nasal function. t therefore seems likely that improved nasal patency may lleviate snoring and sleep-disordered breathing.3,4 Traditional surgical management of nasal obstruc...

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 g...

Suture techniques for reshaping the nasal tip have been in use for many decades. However, the past two decades have been the most influential in the advancement of the procedures commonly used today. This report details the origin of the major tip suture techniques and tracks their evolution through the years. The early techniques in tip rhinoplasty share a basic principle: the sacrifice of lat...

BACKGROUND Transverse nasal crease is an uncommonly reported entity. It likely represents an embryologic fault line. Transverse nasal milia have also been reported in the same location, both as an isolated finding and in a transverse nasal crease. This observation suggests they are variants of the same entity. OBSERVATIONS Two cases, one of transverse nasal crease with milia and one of transv...

Oligodendrocytes are the myelin-forming cells in the central nervous system. In the brain, oligodendrocyte precursors arise in multiple restricted foci, distributed along the caudorostral axis of the ventricular neuroepithelium. In chick embryonic hind-, mid- and caudal forebrain, oligodendrocytes have a basoventral origin, while in the rostral fore-brain oligodendrocytes emerge from alar terri...
