[BACKGROUND] Arteriovenous malformations (AVMs) are rare vascular anomalies associated with considerable morbidity and high recurrence rates. Their management remains challenging, with no universally accepted protocol. This study presents a…

This study introduces a novel application of 3D printing technology to improve the precision of nasal osteotomy for crooked nose correction. A customized 3D-printed surgical guide was applied in ten patients, enabling highly accurate osteot…

[BACKGROUND] Short nose correction in Asian rhinoplasty is challenging due to weak septal cartilage, thick skin envelopes, and strong postoperative contractile forces that compromise long-term tip stability. [OBJECTIVES] This study aimed t…

Facial lymphedema (FL) is a potential complication following head-and-neck tumor (HNT) therapy. Conservative management is often difficult, and there is limited literature on surgical treatments for FL. This report presents three cases of F…

The increasing necessity for solo surgery in plastic and reconstructive microsurgery is driven by contemporary challenges such as a growing and aging population, a shortage of qualified assistants, and the ongoing recovery efforts from COVI…

The anterolateral thigh (ALT) free flap is widely used in reconstructive microsurgery for its versatility and reliability, yet donor site management becomes challenging when flap dimensions exceed those for tension-free primary closure. The…

Total laryngopharyngectomy for advanced hypopharyngeal and laryngeal cancers results in complex defects that compromise both swallowing and phonation. Restoration of these functions is critical for quality of life, yet reconstructive option…

The aim of our study is to investigate whether adjunct neuromuscular electrical stimulation (NMES) therapy improves functional performance outcomes in children with cerebral palsy (CP) who have received botulinum toxin (BTX) injections. We …

[INTRODUCTION] Lymphedema, a debilitating characterized by localized fluid retention and tissue swelling, results from abnormalities in the lymphatic system. In the case of primary lymphedema, this condition is attributed to malformations i…

Aesthetic rhinoplasty relies on a stable framework for long-term structural integrity, often requiring autogenous cartilage grafts. While conchal cartilage is commonly used, its volume may be insufficient, particularly in secondary or revis…

Asian double eyelid blepharoplasty and medial canthoplasty aim to enhance eye appearance in individuals of Asian descent. Traditional methods have limitations and may cause complications. This study introduces a microsurgical approach, offe…

[BACKGROUND] Aesthetic standards vary and are subjective; artificial intelligence (AI), which is currently seeing a boom in interest, has the potential to provide objective assessment. [OBJECTIVES] The aim of this study was to provide a re…

[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…

[BACKGROUND] Traditionally, radial forearm free flaps are utilized for nasal lining reconstruction when local flaps cannot provide adequate coverage. However, according to our clinical observation, the skin of the forearm flap is relatively…

[BACKGROUND] Facial paralysis can affect periorbital muscles, oral competence, and facial expressions with significant facial deformities, which could occur in either children or adults with variable severity, duration, and degree of recove…

(1) Background: The purpose of this study was to determine whether the drooling of adult patients with diverse central nervous system diseases can be treated with botulinum toxin type A. (2) Methods: The Cochrane Library, MEDLINE, and Embas…

[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. The …

[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 t…

[BACKGROUND] The profunda artery perforator (PAP) flap has been reported in several types of reconstructions. This report aims to evaluate the usefulness and the clinical outcome of patients who underwent the PAP free flap for lower limb re…

Since the introduction of the angiosome concept, many attempts have been made to push the dimensional limits of free tissue transfers. While initially limited by the boundaries of random vascularization of adjacent angiosomes, wider flaps w…

[BACKGROUND]  Various studies have discussed the benefits of applying three-dimensional (3D) techniques, specifically its advantages with respect to ergonomics, feasibility, and the rate of learning achievable in microsurgery training. Howe…

Several reconstructive methods have been reported to restore the continuity of the aerodigestive tract following resection of pharyngeal and hypopharyngeal cancers. However, high complication rates have been reported after voice prosthesis …

Tumoral involvement of the carotid artery may require en-bloc resection in order to achieve a better regional control. Among the carotid reconstruction methods at disposal, autologous tissues appear to be more reliable in cases with high ri…

[INTRODUCTION] Patients with head and neck cancer may suffer from xerostomia after repetitive surgery or radiation therapy. Free colon tissue transfer was used to restore the lubrication of the oral cavity, and a bacteriological study in mi…

Patients suffering from hypopharyngeal cancer commonly present in the advanced stage and undergo a circumferential pharyngolaryngectomy. The possibility to reconstruct the esophagus and achieve an oral alimentation can significantly reduce …

Tracheoesophageal puncture (TEP) and voice prosthesis insertion following laryngectomy may fail to form an adequate seal. When spontaneous closure of the fistula tract does not occur after conservative measures, surgical closure is required…
