BACKGROUND AND PURPOSE The cause and clinical relevance of upper neck ligament high signal intensity on MR imaging in WAD are controversial. The purpose of this study was to explore changes in the signal intensity of the alar and transverse ligaments during the first year after a whiplash injury. MATERIALS AND METHODS Dedicated high-resolution upper neck proton attenuation-weighted MR imaging...

Introduction Dysfunctional transverse and alar craniovertebral ligaments can cause instability and osseous destruction in rheumatoid arthritis (RA). This study examined (1) the feasibility of high-resolution magnetic resonance imaging (MRI) of these ligaments in RA and (2) the relation between ligament high-signal changes and atlantoaxial subluxation and RA duration/severity. Methods Consecutiv...

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...

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...

OBJECTIVE To apply a mathematical model to determine the relative effectiveness of various tip-plasty maneuvers while the lateral crura are in cephalic position compared with orthotopic position. METHODS A Matlab (MathWorks, Natick, Massachusetts) computer program, called the Tip-Plasty Simulator, was developed to model the medial and lateral crura of the tripod concept in order to estimate t...

The nasolabial cyst is classified as a fissural cyst, found outside the bone, and on the region corresponding to the nasolabial furrow and alar nose. This cyst is frequently asymptomatic with the most usual sign being alar nose elevation. In spite of the low occurrence of nasolabial cysts, it is important to recognize the clinical characteristics of this lesion. The purpose of this paper is to ...
