Alar base retraction is a common yet difficult problem faced by the rhinoplasty surgeon. It may be caused by weakened, overresected lateral crura, vestibular lining deficiencies, or congenital alar malpositioning. Methods of correction include soft tissue manipulation, auricular composite grafting, and cartilage grafting. We present the senior author's graded approach to alar retraction using a...

BACKGROUND The nasal ala is an attractive site for pulse oximetry because of perfusion by branches of the external and internal carotid arteries. We evaluated the accuracy of a novel pulse oximetry sensor custom designed for the nasal ala. METHODS After IRB approval, healthy non-smoking subjects [n=12; aged 28 (23-41) yr; 6M/6F] breathed hypoxic mixtures of fresh gas by a facemask to achieve ...

Background Nasal reconstruction presents a challenge for plastic surgeons due to the prominent location and complex structure of the nose. When reconstructing full-thickness nasal defects, options to replace the inner lining, cartilaginous framework and outer skin must be considered. The aesthetic units of the nose must also be replaced in full rather than simply filling holes. This report pres...

BACKGROUND/AIM This study aimed to generate data for the S1 and S2 alar pedicle and body and the alar orientations for both dysmorphic and normal sacra. MATERIALS AND METHODS The study comprised two groups: Group N consisted of 53 normal sacra and Group D included 10 dysmorphic sacra. Various features such as alar pedicle circumference; anterior, middle, and posterior axis of the sacral ala; ...

This paper focuses on the problem of how to allow a source to send a message without revealing its physical location and proposes an anti-localization routing protocol, ALAR, to achieve anonymous delivery in Delay/Disruption Tolerant Networks. The objectives of ALAR are to minimize the probability of a data source being localized and to maximize the destination’s probability of receiving the me...

Objectives: We present our 3 years experience with alar batten grafts, using a modified technique, for non-iatrogenic nasal valve/alar

BACKGROUND AND PURPOSE Evaluation of alar traumatic injuries by using MR imaging is frequently performed. This study investigates the variability of morphology and signal intensity of alar ligaments in healthy volunteers so that pathology can be more accurately defined. MATERIALS AND METHODS Fifty healthy volunteers were examined on a 1.5T MR imaging scanner with 2-mm PD-weighted sequences in...

This article describes the management of chemical burns to the Asian face with resultant full thickness loss to the right side of the face including the eyelid and nose. We detail the techniques used to reconstruct the face which include skin grafting according to the aesthetic units of the face, accurate placement of junction lines, use of a chondrocutaneous graft to reconstruct the alar grove...
