Pyoderma gangrenosum (PG) is a rare inflammatory skin disease that is difficult to diagnose. PG may be an extra-intestinal manifestation of ulcerative colitis (UC). In recent times, coronavirus disease (COVID-19) vaccines have caused variou…

[BACKGROUND] Polylactic acid (PLA) is extensively used in the medical and cosmetic industries for skin regeneration and as a dermal filler due to its biocompatibility and biodegradability. However, the effectiveness of PLA as a cosmetic fil…

[BACKGROUND] This study investigated the effects of combining an auricular composite graft with rib cartilage-based rhinoplasty to correct contracted noses in Asian patients with a history of multiple previous operations. [METHODS] A total…

This article explores advancements in functional tongue reconstruction after cancer ablation, focusing on the importance of flap selection, positioning, and volume adjustment to restore speech and swallowing function. It highlights advancem…

[BACKGROUND] Achieving optimal functional speech outcomes is essential in tongue reconstruction. Variables such as recipient artery, tumor size, and radiotherapy can impact tongue movement and speech outcome. Various tongue resection types …

[BACKGROUND] The standard procedure for managing skeletal class III malocclusion is maxillary advancement with mandibular setback. Occlusal plane-altering orthognathic surgery, such as jaw rotation, is useful as well. Although clockwise jaw…

[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…

[PURPOSE] Capsular contracture is a rare but serious complication of silicone implant-based augmentation rhinoplasty. When severe, the contracture can affect all layers of the nose, causing significant scarring and disfigurement. There is c…

[OBJECTIVE] Primary nasal correction has been demonstrated to be a beneficial practice for patients with unilateral cleft lip and palate. However, there is currently no consensus among cleft surgeons regarding the ideal approach to addressi…

This study aimed to present a novel markerless augmented reality (AR) system using automatic registration based on machine-learning algorithms that visualize the facial region and provide an intraoperative guide for facial plastic and recon…

In this study, the authors introduced a dual application of patient-specific occlusion-based positioning guide and fibular cutting guide to obtain ideal occlusal relationship and mandibular contour in patients undergoing mandibular reconstr…

[PURPOSE] This study aimed to compare the effects of motor-innervated free flap on sequential changes of swallowing function in patients undergoing total or near-total glossectomy with laryngeal preservation. [MATERIALS AND METHODS] The me…

In general, flap volume decreases over time and further in the case of a denervated muscle flap. In our institution, dynamic reconstruction, including functional muscle flaps, has been used to aid functional recovery in the past 6 years. Th…

In this study, the authors report the experience of extended superficial musculoaponeurotic system (SMAS) face-lift with the vertical vector in Asian ethnicity and investigate the 3-dimensional change of facial contour. A total of 32 patien…

This study aimed to evaluate functional and aesthetic outcomes in patients undergoing deep-plane facelifts for the management of extensive hemifacial tumors. The retrospective study included patients who had been diagnosed with benign tumor…

[OBJECTIVE] This study investigated various manifestations of nasal deformities in lesser-form cleft lips, including the minor-form, microform, and mini-microform, by photogrammetric comparison with incomplete cleft lips. [DESIGN] Retrospe…

[OBJECTIVES] Owing to the functional and structural complexity of the head and neck area, the reconstruction of defects in these areas is challenging. Free flap surgery has become standard for the reconstruction of the head and neck with im…

Reconstructive surgery in the management of head and neck cancer has evolved to include structure-specific approaches in which organ-specific treatment algorithms help optimize outcomes. Tongue cancer management and reconstruction are surgi…

[BACKGROUND]  The difficulty of elevating a deep inferior epigastric perforator (DIEP) flap largely depends on the intramuscular course of the vessel and the perforator. Previous studies, however, have lacked histologic descriptions of the …

Tongue reconstruction remains a major aspect of head and neck reconstructive procedures. Surgeons planning tongue reconstruction should consider several factors to optimize the overall outcomes. Specifically, various technical aspects relat…

[BACKGROUND] An adequate volume of the tongue flap is essential to preserve speech and swallowing functions. However, it is generally known that the volume of the free flap tends to decrease over time because of various reasons. Especially …
