Quantitative Analysis on Cartilage Growth Between Ipsilateral and Contralateral Donor Sites in Microtia Patients.

Background: Costal cartilage harvest is required in patients with unilateral microtia when autologous reconstruction is being considered. However, whether an ipsilateral or contralateral donor site should be used remains controversial. This is the first study to compare cartilaginous growth between ipsilateral and contralateral donor sites in patients with unilateral microtia.

Efficacy assessment for low-level laser therapy in the treatment of androgenetic alopecia: a real-world study on 1383 patients.

Low-level laser therapy (LLLT) has been a treatment modality by many androgenetic alopecia (AGA) patients in recent years. It remained unclear as to how long the treatment regime should be maintained, and which characteristics of patients should this be recommended. A real-world study was carried out with an FDA-cleared low-level laser helmet for 1383 patients.

Effect of Behavioral Factors on Severity of Female Pattern Hair Loss: An Ordinal Logistic Regression Analysis.

Female pattern hair loss (FPHL) is one of the most common types of hair loss with complex genetic predisposition. A frontal pattern hair loss with ponytail hairstyle is pervasively seen among young Chinese women. The purpose of this study is to investigate the association between the severity of FPHL and behavioral factors which include dietary, and sleep habits, and to test the hypothesis on whether ponytail hairstyle is an independent factor that increases the risks of being more severe on the FPHL scale.

Sustained release of dermal papilla-derived extracellular vesicles from injectable microgel promotes hair growth.

Hair regeneration has long captured researchers' attention because alopecia is a common condition and current therapeutic approaches have significant limitations. Dermal papilla (DP) cells serve as a signaling center in hair follicles and regulate hair formation and cycling by paracrine secretion. Secreted EVs are important signaling mediators for intercellular communication, and DP-derived extracellular vesicles (DP-EVs) may play an important role in hair regeneration.

Validity and reliability of three-dimensional costal cartilage imaging for donor-site assessment and clinical application in microtia reconstruction patients: A prospective study of 22 cases.

Objectives: This study assesses the ability to reconstruct costal cartilage images by using three-dimensional visualisation software (Mimics) based on semi-automated segmentation algorithm and to investigate its reliability and validity with an anthropometric analysis.

Design: Observational prospective study.

Setting: Plastic surgery department of a tertiary hospital.

The Clinical Application of Medial Sural Vessels as Recipient Vessels in Repairing Traumatic Tissue Defects in the Lower Limbs.

Background: The use of medial sural vessels (MSVs) as recipient vessels to repair wounds in the lower limbs has been previously reported. However, there is controversy regarding the methods used to expose MSVs and the repairable area of the wound.

Methods: Eight fresh cadavers were used to determine the shape, outer diameter, and length of the MSVs arising from the popliteal vessels.

Hydroxytyrosol prevents dermal papilla cells inflammation under oxidative stress by inducing autophagy.

Hydroxytyrosol (HT), a primary phenolic antioxidant in olive oil, can afford protection from oxidative stress (OS) in different cells, including skin cells. In particular, it regulates several inflammation-associated processes as well as in improving the antioxidant defense system. However, there is no information about HT used in the treatment of hair loss.
