Botulinum toxin therapy for neurological disorders: Serendipitous benefits on sleep quality and underlying mechanisms.
Botulinum toxin (BoNT) remains the gold standard treatment for focal and segmental dystonia and is widely used in managing hyperkinetic disorders, chronic pain, and glandular hypersecretion. Extensive clinical trials demonstrate that BoNT e…

Attenuated Angiogenesis and Macrophage Infiltration during Adipose Tissue Regeneration in Megavolume Human Fat Grafting.
[BACKGROUND] Survival and regeneration mechanisms of large (>250 mL) fat grafts remain incompletely understood. In fat grafts from volunteers with megavolume fat transfer breast augmentation, neovascularization and inflammatory cell infiltr…

Medial sural artery perforator free flap versus radial forearm free flap in oral cavity reconstruction and donor site morbidity.
[OBJECTIVE] Radial Forearm Free flap (RFFF) is widely used in head and neck reconstruction, yet its donor site defect remains a significant drawback. The Medial Sural Artery Perforator Free Flap (MSAPFF) is considered an alternative flap to…

Fibular free flap necrosis after mandibular reconstruction surgery with osteoradionecrosis: Establishment and verification of an early warning model.
[OBJECTIVE] Fibular free flap necrosis (FFFN) is the most common complication in patients with osteoradionecrosis (ORN) after mandibular reconstruction surgery. However, there are no effective forecasting tools at present. This research is …

Efficacy and Safety of Botulinum Toxin Type A in the Treatment of Trigeminal Neuralgia: An Update on Systematic Review With Meta-analyses.
[OBJECTIVE] Pain management in patients with TN is challenging, as facial pain often does not respond well to conventional therapies. Botulinum toxin type A (BTX-A) has been suggested as a potential treatment option, but there is limited ev…

Perioperative risk factors impact on intensive care unit length of stay (ICU length of stay) in oral squamous cell carcinoma.
[BACKGROUND] The trend in postoperative care for free flap patients is to deescalate from routine ICU admission into a specialty recovery unit. This study aims to investigate the predictive parameters in a routine perioperative clinical ass…

Long-term outcomes of microsurgery and stereotactic radiosurgery as the first-line treatment for arteriovenous malformations: a propensity score-matched analysis using nationwide multicenter prospective registry data.
[BACKGROUND] This study aimed to compare the risk and benefit profile of microsurgery (MS) and stereotactic radiosurgery (SRS) as the first-line treatment for unruptured and ruptured arteriovenous malformations (AVMs). [MATERIALS AND METHO…

Postoperative ecchymoma of eyelid after botulinum toxin injection for hemifacial spasm: a case report.
Hemifacial spasm (HFS) is a rare movement disorder characterized by involuntary muscle contractions on one side of the face. Compared to the high therapeutic effect, adverse effects of botulinum toxin treatment for HFS occurred rarely. Howe…

Sutures positioning technique enhances the predictability and concordance between preoperative simulation and actual outcomes in rhinoplasty.
[BACKGROUND] The predictability and concordance between simulated and actual outcomes in rhinoplasty are uncertain. Here, we introduce a suture positioning technique (SPT), a simple and low-cost method to minimize the gap between the simula…

Machine learning models for prognosis prediction in endodontic microsurgery.
[OBJECTIVES] This study aimed to establish and validate machine learning models for prognosis prediction in endodontic microsurgery, avoiding treatment failure and supporting clinical decision-making. [METHODS] A total of 234 teeth from 17…

Is myasthenia gravis a contraindication for botulinum toxin?
Botulinum toxin (BTX) is a neurotoxin that has been used to treat various disorders and has also become a popular choice for cosmetic indications, yet traditionally, myasthenia gravis (MG) is considered a contraindication for BTX. To determ…

Higher Serum Levels of Lactate Dehydrogenase Before Microsurgery Predict Poor Outcome of Aneurysmal Subarachnoid Hemorrhage.
We explored whether higher preoperative serum levels of lactate dehydrogenase (LDH) predicted outcome 3 months after surgery in patients with aneurysmal subarachnoid hemorrhage (aSAH) treated using microsurgical clipping in our institution.…

Delayed migration of soft tissue fillers in the periocular area masquerading as eyelid and orbital pathology.
Soft tissue fillers used for facial rejuvenation can cause complications. We present two cases of late migration of injected fillers mimicking other pathology in the periocular area. Case 1 is a 52-year-old woman referred with chronic bilat…

Load-induced regulation of tendon homeostasis by SPARC, a genetic predisposition factor for tendon and ligament injuries.
Tendons and tendon interfaces have a very limited regenerative capacity, rendering their injuries clinically challenging to resolve. Tendons sense muscle-mediated load; however, our knowledge on how loading affects tendon structure and func…
