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...

The hypothalamus is an important physiologic center of the vertebrate brain involved in the elaboration of individual and species survival responses. To better understand the ancestral organization of the alar hypothalamus we revisit previous data on ScOtp, ScDlx2/5, ScTbr1, ScNkx2.1 expression and Pax6 immunoreactivity jointly with new data on ScNeurog2, ScLhx9, ScLhx5, and ScNkx2.8 expression...

The aim of this study was to explore whether reported pain and functional disability in whiplash-associated disorders (WAD) patients is associated with lesions to specific soft tissue structures in the upper cervical spine, as assessed by MRI. Pre-selected structures for MRI assessment included the alar ligaments, the transverse ligament, the tectorial and the posterior atlanto-occipital membra...

OBJECTIVE To assess the feasibility and outcome of free cartilage grafts left to heal by secondary intention in the reconstruction of nasal alar skin defects. DESIGN We describe the retrospective analysis of 13 patients who were treated in a single department with the use of free cartilage grafts in combination with secondary intention healing for reconstruction of the alar subunit and latera...

We are in the midst of truly changing times, as patients of African descent actively embrace facial cosmetic surgery. Gaining surgical consistency in patients of African descent has proven to be elusive and unpredictable for many rhinoplasty surgeons. Surgical success relies on the surgeon's ability precisely to identify anatomic variables and reconcile these anatomic realities with the patient...

INTRODUCTION Labial and nasal deformities have always been a fundamental problem in the treatment of cleft lip, alveolus and palate patients. The primary surgical treatment of nasolabial area is of paramount importance in order to obtain both an esthetical correction of the deformity and a progressive and a balanced development of mid-face. In this study the nasal deformities in patients with c...

STUDY DESIGN Case-control study. OBJECTIVE To use high-resolution magnetic resonance imaging (MRI) in assessing signal intensity areas in the alar ligaments. SUMMARY OF BACKGROUND DATA Conflicting evidence exists whether areas of high signal intensity in the alar ligament on MRI are more frequent in whiplash patients than in noninjured control subjects. METHODS A case-control designed stu...

"A smile is happiness you'll find right under your nose"- Tom Wilson. This quote holds true just for patients, not for surgeons. The correction of the nose always poses a challenge to the cosmetic surgeon. Deformities of the external and internal nose may be congenital or acquired and may be secondary to soft tissue and/or osseo-cartilaginous abnormalities, leading to aesthetic and/or functiona...

BACKGROUND Le Fort I osteotomy imparts significant changes to the nasolabial region. Past studies have relied on 2-dimensional data and have not delineated differences among various Le Fort I subtypes. The purpose of this study is to 3-dimensionally analyze Le Fort I-induced nasal and lip changes comparing advancement alone versus widening alone [surgically assisted maxillary expansion (SAME)] ...

BACKGROUND The site, size, and depth of tissue loss, irradiation, or composite injury to adjacent cheek and lip may make local tissues inadequate or unavailable for the repair of major nasal defects. METHODS In 13 patients, a single, folded, horizontal radial forearm flap was used to line the vault and columella, with an incontinuity fasciocutaneous extension to resurface the nasal floor, wit...
