Comprehensive Analysis of Free BDPE Content in Commercial Hyaluronic Acid Fillers: Implications for Safety Assessment and Regulatory Standards.
[BACKGROUND] Although manufacturers of 1,4-butanediol diglycidyl ether (BDDE)-cross-linked hyaluronic acid (HA) fillers assert effective removal of unreacted BDDE, the hydrolyzed derivative 3,3'-(butane-1,4-diyl)bis(oxy)bis(propane-1,2-diol…

Tumor necrosis factor-α-treated human adipose-derived stem cells enhance inherent radiation tolerance and alleviate in vivo radiation-induced capsular contracture.
[INTRODUCTION] Post-mastectomy radiotherapy plays a crucial role in breast cancer treatment but can lead to an inflammatory response causing soft tissue damage, particularly radiation-induced capsular contracture (RICC), impacting breast re…

Use of the frontal branch of the superficial temporal artery and the postauricular vein to overcome anatomic variations of superficial temporal vessels in scalp reconstruction with free tissue transfer: a case report.
The superficial temporal artery (STA) bifurcates into frontal and parietal branches. The parietal branch is used as a recipient vessel for scalp reconstruction, but it is absent in approximately 16.3% of individuals. In this case, a 72-year…

Investigations of Thiosemicarbazides as Botulinum Toxin Active-Site Inhibitors: Enzyme, Cellular, and Rodent Intoxication Studies.
Botulinum neurotoxin type A (BoNT/A) is an exceptionally potent neurotoxin of great therapeutic value; however, it is also considered a weapon of mass destruction, as it is one of the most poisonous biological substances known to man. The e…

Performance of ChatGPT in Answering Clinical Questions on the Practical Guideline of Blepharoptosis.
[BACKGROUND] ChatGPT is a free artificial intelligence (AI) language model developed and released by OpenAI in late 2022. This study aimed to evaluate the performance of ChatGPT to accurately answer clinical questions (CQs) on the Guideline…

Poly Lactic-co-Glycolic Acid Absorbable Plate Graft for Secondary Rhinoplasty in Asian Patients with Unilateral Cleft Lip Nose Deformity.
[INTRODUCTION] In secondary cleft lip and nasal deformity (CLND) correction, structural grafts are commonly used to control the nasal tip and restore the symmetry of the ala. However, the septal cartilage in Asians often weak and small. Bio…

Clinical investigation of botulinum toxin (prabotulinumtoxin A) for bruxism related to masseter muscle hypertrophy: A prospective study.
This study aims to confirm the effectiveness and safety of a prabotulinumtoxin type A (praBTX-A) injection in patients with bruxism and masseter hypertrophy. The study included patients who ground or clenched their teeth while sleeping and …

Functional Outcome Comparison of Free Gracilis Muscle Anchoring Methods in Patients with Facial Paralysis: Upper Lip Red Line Incision versus Facelift Incision Approach.
[BACKGROUND] The greatest challenge of a free-muscle transfer in facial reanimation surgery is anchoring muscle to perioral soft tissue. An additional incision provides a better way to anchor the transferred muscle but leaves a visible sca…

Asian rhinoplasty using a thin rib cartilage graft and ultrafine diced cartilage wrapped in fascia: A comparative study between septal cartilage graft and rib cartilage graft.
[BACKGROUND] A 1-2-mm thin rib cartilage graft was used as a septal extension graft to overcome the drawbacks of traditional rib cartilage rhinoplasty, which often results in a stiff nasal tip. The remaining rib cartilage was placed on the …

Assessment of human adipose-derived stem cell on surface-modified silicone implant to reduce capsular contracture formation.
Medical devices made from poly(dimethylsiloxane) (PDMS)-based silicone implants have been broadly used owing to their inert properties, biocompatibility, and low toxicity. However, long-term implantation is usually associated with complicat…

In vitro and in vivo methods to study bacterial colonization of hydrogel dermal fillers.
Preclinical in vitro and in vivo methods to study bacterial interactions with dermal fillers and infection pathogenesis are lacking. In this work, first in vitro methods to assess protein biofouling and effective pore size of commercial der…

Efficacy and safety of equine cartilage for rhinoplasty: a multicenter double-blind non-inferiority randomized confirmatory clinical trial.
[BACKGROUND] The efficacy and safety of equine cartilage as a competent xenograft material for rhinoplasty were evaluated and compared to the outcomes of rhinoplasty using silicone implants. [METHODS] We performed a multicenter, double-bli…

Dynamic Hemitongue Defect Reconstruction With Functional Gracilis Muscle Free Transfer.
[BACKGROUND] Because the tongue consists of 26 intrinsic and extrinsic muscles, even hemiglossectomy, which preserves some of the tongue and its muscles, leads to functional morbidity in speech and swallowing. Subsequent reconstruction usin…

Impact of Breast Reconstruction on Biophysical Parameters of Mammary Skin in Patients Receiving Postmastectomy Radiotherapy for Breast Cancer.
[PURPOSE] In this study, we examined the impact of reconstruction using tissue expander insertion (TEI) on the risk of radiation dermatitis in patients undergoing postmastectomy radiotherapy (PMRT). [METHODS] Between August 2015 and March …

Negative pressure pulmonary edema in a patient undergoing open rhinoplasty: A case report.
[RATIONALE] Negative pressure pulmonary edema (NPPE) is associated with serious postoperative complications. Compact nasal packing is always done after an open rhinoplasty procedure which makes it difficult to achieve positive pressure vent…

Patient-Specific 3-Dimensional Printed Models for Planning Nasal Osteotomy to Correct Nasal Deformities Due to Trauma.
Nasal deformities due to trauma are more challenging to correct with rhinoplasty than nasal deformities of nontraumatic causes. Nasal osteotomy is an essential procedure for bone deviations. Preoperative planning is vital in these cases, bu…

Modulation of Foreign Body Reaction against PDMS Implant by Grafting Topographically Different Poly(acrylic acid) Micropatterns.
The surface of poly(dimethylsiloxane) (PDMS) is grafted with poly(acrylic acid) (PAA) layers via surface-initiated photopolymerization to suppress the capsular contracture resulting from a foreign body reaction. Owing to the nature of photo…
