Background: Free diced cartilage smaller than 0.2 mm in diameter to smoothen the nasal dorsum is a well-known procedure. However, creating smaller diced cartilage takes a really long time. In contrast, the free diced cartilage technique has some visibility problems, especially in thin-skin patients, although a fine job is done to chop the cartilage. The author aimed to present the “ultra diced cartilage graft” and the way to achieve it, to eliminate the problems of diced cartilage during rhinoplasty, and compare it with free diced cartilage grafting technique. Methods: Between April of 2015 and December of 2018, the ultra diced cartilage graft technique in 104 patients and the free diced cartilage graft technique in 113 patients were used to smoothen the dorsum or augment the radix/dorsum. Operation records, rhinoplasty outcome evaluation questionnaire, palpation test, and evaluation of the immediate postoperative photographs on the table with postoperative 1-year postoperative photographs by two independent blinded plastic surgeons were analyzed. Results: Ultra diced cartilage seemed superior to free diced cartilage grafting with regard to graft visibility and resorption. Conclusions: Ultra diced cartilage graft is an effective and easily reproducible technique in rhinoplasty. There is no extra cost, and it is the easiest and fastest way to have this perfectly pliable cartilage have no dead space. The ultra diced cartilage grafting technique should be known by all plastic surgeons to achieve fineness in rhinoplasty. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

In this paper, an electrochemical application of bismuth‐film electrode (BiFE) fabricated via ex‐situ electrodeposition onto a glassy carbon electrode for testosterone determination was investigated in aqueous and aqueous/surfactant solutions. In cyclic voltammetry, the compound showed one irreversible and adsorption‐controlled reduction peak. The BiFE revealed good linear response in the examined concentration range of 1 to 45 nmol L−1 testosterone in BrittonRobinson buffer, pH 5.0 containing 3 mmol L−1 cetyltrimethylammonium bromide. The limit of detection was 0.3 nmol L−1 (0.09 ng mL−1). Finally, the BiFE was satisfactorily applied for quantitation of testosterone in both pharmaceutical (oil‐based ampoule) and biological (human urine) samples.

The anatomy of the nasal muscles contributes a social harmony in aesthetic rhinoplasty because these muscles coordinate the nose and the upper lip while smiling. Sometimes this coordination can be interrupted by the hyperactivity or variations of these muscles and may result as a deformity because of their dynamic functions and relations with the nose. In our daily practice, we usually perform the rhinoplasty without considering the dynamic functions. When the patients recover the muscle functions after operation and start to use their mimics, such as smiling, the undamaged dynamic forces may start to rotate the tip of the nose inferiorly in a long-term period, correlated with their preoperative function. To avoid this unexpected rotation it is essential to remember preoperative examination of the smile patterns. To manage this functional part of rhinoplasty, we aimed to clarify the smiling patterns or deformities mainly focused on depressor septi nasi muscle in this article. This muscle creates downward movement of the nasal tip and shortens the upper lip during smiling. The overactivity of this muscle can aggravate the smiling deformity in some patients by a sharper nasolabial angle correlated with levator labii superioris alaeque nasi and orbicularis oris muscle activities. The article not only stresses the correction of this deformity, but also aims to guide their treatment alternatives for correlation of postoperative results and applicability in rhinoplasty.
