In the era of supermicrosurgery, clinicians need more precise imaging modalities to know the exact microvascular and lymphatic anatomy of the patient. The goal of this review is to answer the research question "What are the state-of-the-art…

Supermicrosurgery involving vessels ≤0.3 mm remains among the most technically demanding procedures in reconstructive surgery. Robotic platforms have shown potential to enhance precision, but their feasibility at this extreme scale requires…

Perforator flaps have transformed reconstructive microsurgery by enabling tissue-specific reconstruction while preserving muscle, fascia, and nerves, minimizing donor site morbidity. Modern techniques-including superthin, ultrathin, and pur…

This study investigates the impact of preoperative ultrasound mapping using color Doppler ultrasound (CDU) on surgical outcomes for anterolateral thigh (ALT) free flap reconstructions.A retrospective review was conducted on patients who wer…

Many young microsurgeons begin their careers at established hospitals where microsurgery resources are limited. This article shares the authors' experiences in overcoming challenges and establishing a microsurgery practice in a new hospital…

[BACKGROUND] The authors investigated postoperative nasal morphologic changes in patients undergoing secondary correction of cleft-lip nose with septal repositioning and alar cartilage suspension during preschool age. [METHODS] The authors…

[BACKGROUND] One of the critical factors for free flap survival is to maintain adequate perfusion. The authors evaluated the effect of epidural anesthesia on arterial maximal flow velocity of the free flap in microvascular lower extremity r…

[BACKGROUND] To perform head and neck reconstruction, the exact location of recipient vessels must be evaluated preoperatively. This study aimed to superimpose arterial and venous pathways identified by computed tomography angiography (CTA)…

[BACKGROUND] This retrospective case series compares the outcomes and postoperative oxygen levels in patients who underwent free flap versus primary closure/local flap reconstruction for ischemic diabetic foot wounds to determine the influe…

[BACKGROUND]  Transmetatarsal amputation (TMA) preserves functional gait while avoiding the need for prosthesis. However, when primary closure is not possible after amputation, higher level amputation is recommended. We hypothesize that rec…

[BACKGROUND] Although the effects of botulinum toxin A on hernia reconstruction have been consistently reported, few studies provide objective evidence. The authors aimed to compare the effects of chemical component separation with those of…

[BACKGROUND]  With the technological advances, microsurgery has evolved to the era of supermicrosurgery since its inception. With the popularization of these flaps, proficiency in using tools such as color Doppler ultrasound (CDU) has becom…

[BACKGROUND] Total breast reconstruction involves a long process consisting of mastectomy, breast reconstruction, and adjuvant therapy. For various reasons, some patients refuse the final step of nipple-areola reconstruction. Some patients …

[BACKGROUND] Recently, the mandibular body and chin shape are known to be important issue as well as the mandibular angle. The authors have performed the one-piece mandibuloplasty from the mandibular angle to the most anterior part of chin …
