BACKGROUND Understanding the anatomy of nasal cartilage, which varies by ethnic group, is important for surgical correction of nasal tip deformities. OBJECTIVES The authors measure the size and shape of the lower lateral cartilages (LLC) in Persian cadavers to provide summary guidelines. METHODS A total of 72 cartilage dissections were performed on 36 fresh Persian cadavers. All soft tissue...

OBJECTIVES In this study, a modified surgical method was carried out to repair large nasal septal perforations with a galeal pericranial flap using endoscopic technique. MATERIALS AND METHODS Six adult human cadavers were dissected by applying the classic open rhinoplasty technique. Large perforations were created in the septal cartilages. To repair the perforations, we prepared galeal pericr...

Introduction: Cartilaginous nasal septal agenesis is a rare finding. In fact, just one case has been reported to have congenital agenesis of all nasal cartilages in a 6-year-old child by Bakhshaee et al. The literature review shows another case that was reported by Ozek et al in Turkey, where they reported a case of total nasal agenesis that was associated with Tessier no. 30. We could not find...

One of the most difficult aspects in rhinoplasty is resolving and preventing functional compromise of the nasal valve area reliably. The nasal valves are crucial for the individual breathing competence of the nose. Structural and functional elements contribute to this complex system: the nasolabial angle, the configuration and stability of the alae, the function of the internal nasal valve, the...

OBJECTIVE To review the indications for, surgical techniques of, and results of vertical lobule division (VLD) of the alar cartilages. DESIGN Prospective study of patients assigned to undergo variations of VLD of the lower lateral cartilages. SETTING Private facial plastic surgery practice in a major university teaching hospital. PATIENTS Twenty-four patients who underwent variations of V...

1 Shu Jin Lee, MD Kathleen Ong Department of Surgery National University Health System Singapore Sir: W describe an unusual case of multiple trauma in which the patient fell from a height of 20 m, sustaining panfacial fractures with severe nasoethmoid fractures and soft tissue concertina of the entire bony cartilaginous complex of the nose together with an open fracture of the right humerus com...

BACKGROUND Preoperative planning of nasal tip surgery requires an accurate assessment of the nasal tip cartilages configuration. The current literature lacks any evidence on the accuracy of preoperative assessment of the lower lateral cartilages (LLC) shape. OBJECTIVE This study was designed to determine the accuracy of the LLC shape and configuration assessment prior to dissection. METHODS...

The purpose of this study is to investigate the spacial expression pattern and functional significance of three key transcription factors related to bone and cartilage formation, namely, Sox9, Runx2, and Osterix in cartilages during the late development of mouse mandible. Immunohistochemical examinations of Sox9, Runx2, and Osterix were conducted in the mandibular cartilages of the 15 neonatal ...

presented is a method of two-dimensional analysis of the active earth pressure due to simultaneous effect of both soil weight and surcharge of strip foundation. the study’s aim is to provide a rigorous solution to the problem in the framework of upper-bound theorem of limit analysis method in order to produce some design charts for calculating the lateral active earth pressure of backfill when ...
