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...

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...

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...

GUIDELINES Viewpoints, pertaining to issues of general interest, are welcome, even if they are not related to items previously published. Viewpoints may present unique techniques , brief technology updates , technical notes, and so on. Viewpoints will be published on a space-available basis because they are typically less time-sensitive than Letters and other types of articles. Please note the ...

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: Nasal alar retraction deformities occasionally require both soft tissue release and large cartilage grafts. The structure between the upper lateral cartilage and the lateral crus of the lower lateral cartilage has been described as fibrous tissue, intercartilaginous ligament, ligament-like arrangement or connective tissue. Despite its importance, no anatomical and histological examin...

A retrospective study was conducted of 150 consecutive secondary rhinoplasty patients operated on by the author before February of 1999, to test the hypothesis that four anatomic variants (low radix/low dorsum, narrow middle vault, inadequate tip projection, and alar cartilage malposition) strongly predispose to unfavorable rhinoplasty results. The incidences of each variant were compared with ...
