OBJECTIVES To describe various techniques, including alar base reduction, alar flaring reduction, and alar hooding reduction and present a decision-making treatment algorithm and quantifiable guidelines for soft-tissue excision, along with scar outcomes from a single-surgeon practice. The soft tissue of the nasal tip, ala, and nostrils is important in overall nasal tip dynamics. Excisional alar...

BACKGROUND In critically ill patients, clinicians can have difficulty obtaining accurate oximetry measurements. OBJECTIVE To compare the accuracy of nasal alar and forehead sensor measurements and incidence of pressure injury. METHODS 43 patients had forehead and nasal alar sensors applied. Arterial samples were obtained at 0, 24, and 120 hours. Oxygen saturations measured by co-oximetry we...

OBJECTIVES To simplify the approach and diagnosis of alar base reduction, suggest a treatment algorithm, and evaluate the long-term outcomes of 3 different techniques used separately or in conjunction with one another. DESIGN Retrospective review of 124 patients seen in a private practice by a single surgeon. Patients ranged in age from 15 to 59 years (mean age, 30.4 years). Patients were und...

OBJECTIVE To statistically analyze the long-term results of alar base reduction after rhinoplasty. METHODS Among a consecutive series of 100 rhinoplasty cases, 19 patients required alar base reduction. The mean (SD) follow-up time was 11 (9) months (range, 2 months to 3 years). Using preoperative and postoperative photographs, comparisons were made of the change in the base width (width of ba...

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 ...

In full-thickness defects of the nasal alar rim, to achieve projection and maintain airway patency, cartilage graft is frequently needed. However, cartilage graft presents a challenge in considerations such as appropriate donor site, skeletal shape and size, and healing of the donor area. To avoid these demerits, we tried primary closure of alar rim defects by also making the contralateral norm...

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
