Forehead Flap Reconstruction in Different Nasal Defect: 58 Patients' Psychological Outcomes.

Forehead flap nasal reconstruction is a lengthy process; the final outcome requires multiple stages and several months to achieve. After flap transfer, the pedicle flap has to be kept attached to the face for weeks, which may lead to a variety of psychosocial distress and challenges for patients. From April 2011 to December 2016, 58 patients who underwent forehead flap reconstruction for nasal reconstruction were included.

Alar Crease Creation Suture in Nasal Reconstruction.

Summary: The crescentic alar groove serves as a topographic landmark that frames the ala and separates this convex structure from the surrounding cosmetic subunits. This aesthetic landmark can be attenuated or even obliterated during wound repair in this area. Flaps spanning the alar crease are often noticeably bulky with a pin-cushioned appearance in nasal reconstruction, and it is challenging to reproduce a natural-appearing alar groove.

Machine learning approach for predicting inhalation injury in patients with burns.

Background: The coronavirus disease pandemic has had a tangible impact on bronchoscopy for burn inpatients due to isolation and triage measures. We utilised the machine-learning approach to identify risk factors for predicting mild and severe inhalation injury and whether patients with burns experienced inhalation injury. We also examined the ability of two dichotomous models to predict clinical outcomes including mortality, pneumonia, and duration of hospitalisation.

Objective Comparison of Eyebrow Position after Internal and External Browpexy.

Background: Several brow-lift techniques have been used to prevent brow ptosis after blepharoplasty. For example, both internal and external browpexies have been adopted worldwide. However, few studies have compared these two methods.

Simultaneous free flap and forehead flap for nasal reconstruction.

Background: Reconstruction of total or near-total nasal defects is challenging and requires the re-creation of three nasal layers. Fasciocutaneous free flaps have been used effectively for restoring the vascularized nasal lining and staged forehead flap for nasal skin replacement, which is a long process. The aim of this study is to share our experience of combination of preliminary free tissue transfer with paramedian forehead flap reconstruction in the same stage of complex nasal reconstruction.

Carbon Dioxide Laser Transconjunctival Lower Blepharoplasty: An Objective and Quantitative Comparison to Monopolar Electrosurgery.

Background: The ability to simultaneously cut and perform hemostasis with low lateral thermal injury makes carbon dioxide laser a useful tool in blepharoplasty. Monopolar electrosurgery is another commonly used cutting tool that improves the quality of hemostasis and cutting speed. This study aimed to objectively and quantitatively assess the intraoperative and postoperative outcomes of transconjunctival lower blepharoplasty using either a carbon dioxide laser or monopolar electrosurgery.

ENERGI-F703 gel, as a new topical treatment for diabetic foot and leg ulcers: A multicenter, randomized, double-blind, phase II trial.

Background: Diabetic foot and leg ulcers are a major cause of disability among patients with diabetes mellitus. A topical gel called ENERGI-F703, applied twice daily and with adenine as its active pharmaceutical ingredient, accelerated wound healing in diabetic mice. The current study evaluated the safety and efficacy of ENERGI-F703 for patients with diabetic foot and leg ulcers.

A Combination of Three-Step Lower Blepharoplasty to Correct Four Types of Lower Eyelid Deformities in Asian People.

Background: This study aimed to propose a novel four-type deformity and treatment-oriented classification of the lower eyelids that directs the therapeutic combination of three-step lower blepharoplasty for Asian populations.

Methods: We reviewed 183 patients who underwent a therapeutic combination of three steps of lower blepharoplasty after being diagnosed with four types of lower eyelid deformities between July 2018 and April 2021. The three-step lower blepharoplasty includes: (1) mid-face and lower eyelid augmentation, (2) transconjunctival eye bag removal, and (3) skin pinch removal.

Selection of Site for Harvesting Dermal Grafts as a Spacer in the Correction of Eyelid Retraction.

Background: Several materials can serve as spacer grafts in the repair of retracted lower eyelids. However, previous studies did not reveal any of these to be superior to the others. From our perspective, autologous dermal grafts are ideal because they are biologically compatible and abundantly available.

Unusual presentation of linear wrist blisters associated with hereditary angioedema: The first case report in Taiwan.

Hereditary angioedema (HAE) is an autosomal dominant disease characterized clinically by recurrent episodes of swelling in the tissues of the extremities, face, abdomen, and respiratory tract. It is most often caused by C1 esterase inhibitor (C1 INH) gene mutation. This swelling may lead to bradykinin release, resulting in recurrent, paroxysmal, painful angioedema.

A Comparative Study Between Classic Derotation Graft and Novel Double V Cutting Folded Derotation Graft.

Background: To introduce an innovative refinement, the "double V cutting folded derotation graft" (DVCFD graft), which is a method for nasal tip lengthening in aesthetic rhinoplasty with strong holding force and efficient cartilage use.

Methods: A retrospective study was conducted from January 2018 to July 2019 with 101 patients, including 11 males and 90 females with an average age of 36.87 ± 10.

The Upper Buccal Musculomucosal Flap for Nasal Lining and Columellar Defect Reconstruction.

Restoring the nasal lining is a great challenge in the reconstruction of nasal defects. In this series, the authors present our experience in using the upper buccal musculomucosal (UBMM) flap for the reconstruction of full thickness columellar or nasal lining defects. Ten patients who underwent UBMM flap reconstruction of columellar or nasal lining defects, with or without composite grafting, were identified between December of 2014 and February of 2017.

Disseminated intravascular coagulation in Stevens-Johnson syndrome and toxic epidermal necrolysis.

Background: Patients with Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN) have high mortality rates. Disseminated intravascular coagulation has been reported in SJS/TEN patients. The influence of this lethal complication in patients with SJS/TEN is not well known.

Paranasal Augmentation With Composite Graft Transfer in Overresection of Alar Base and Nostril Contracture.

Background: Many Asian patients desire a narrower nasal base with less flaring of the alar lobules. However, patients who underwent multiple rhinoplasty surgeries with nostril contracture or an overreduction of the alar base may experience nostril contracture and deformity, which may lead to further airway obstruction. We present a technique that combines paranasal augmentation with composite chondrocutaneous graft transfer to overcome this problem.

Development of a semi-structured, multifaceted, computer-aided questionnaire for outbreak investigation: e-Outbreak Platform.

Aggressive tracing of contacts of confirmed cases is crucial to Taiwan's successful control of the early spread of COVID-19. As the pandemic lingers, an epidemiological investigation that can be conducted efficiently in a timely manner can help decrease the burden on the health personnel and increase the usefulness of such information in decision making. To develop a new tool that can improve the current practice of epidemiological investigation by incorporating new technologies in digital platform and knowledge graphs.

Preventing nasal airway collapse with irradiated homologous costal cartilage versus expanded polytetrafluoroethylene: a novel animal model for nasal airway reconstruction.

Airway collapse can occur when the forces of inhalation overpower the strength of the nasal lining flap. The authors established an animal model of the reconstructed nasal airway, and examined mechanical properties of tissue composites based on various materials. Twenty-three Sprague-Dawley rats were divided into three experimental groups: control (n = 5), irradiated homologous costal cartilage (IHCC, n = 10), and expanded polytetrafluoroethylene (ePTFE, n = 8).

Management of Major Burns in 37 Casualties of a Colored Powder Explosion: Experience of the Linkou Burn Center in Taiwan.

Background: On June 27, 2015, a colored powder explosion occurred in Taiwan. As a result, 499 people were injured, and over 200 people were in critical condition because of severe burns. Forty-nine casualties were transported to the Chang Gung Memorial Hospital.

How to Prevent Costal Cartilage Graft Warping in Secondary Correction of Cleft Lip Nasal Deformity.

Introduction: Autologous costal cartilage dorsal onlay graft is widely used for dorsum and radix augmentation in secondary cleft lip nasal rhinoplasty. The most common drawback of costal cartilage dorsal onlay graft is warping. The purpose of this article is to describe our chimeric autologous costal cartilage graft technique, which prevents warping significantly.

Nose resurfacing with free fasciocutaneous flaps in burns patients.

Background: Nasal reconstruction after burn injury can be challenging due to limited availability of local flaps. We present our experience of free flap reconstruction for full-thickness nasal defect after severe facial burn injury.

Methods: Between August 1998 and September 2015, six patients underwent nasal reconstruction with seven free flaps after burn injury.

The Influence of Paranasal Augmentation on the Measurement of the Nose for the Treatment of Midfacial Concavity.

Background: A concave midface with its associated deep nasolabial folds is more aesthetically displeasing than a convex midface. Midfacial concavity may be addressed with autologous tissue and implants.

Objectives: The aim of this study was to determine the effect of paranasal augmentation on photogrammetric parameters.

Hyperphosphatemia is associated with high mortality in severe burns.

Introduction: Phosphate level is often deranged during acute illness, regardless of the presence of kidney injury or not. A few studies described that hypophosphatemia may associated with outcome in patients admitted to the burn unit, but the literatures for hyperphosphatemia is limited. Our study aims to evaluate if hyperphosphatemia, one of the sign of severe tissue damage or kidney injury, will associate with mortality of patients with severe burns.

Comparison of Steroid and Botulinum Toxin Type A Monotherapy with Combination Therapy for Treating Human Hypertrophic Scars in an Animal Model.

Background: The authors evaluated the efficacy of a combined regimen of botulinum toxin type A (Botox) and a steroid (triamcinolone acetonide) for treating hypertrophic scars in comparison with the treatment with each drug alone.

Methods: Twenty excised human hypertrophic scar fragments obtained from surgically treated burn patients were divided into four groups: negative control (group A), triamcinolone alone (group B), Botox alone (group C), and a combination of triamcinolone and Botox (group D). These specimens were implanted into the backs of nude mice after intralesional injection from each group and were observed for 4 weeks.
