[UNLABELLED] Introduction: Trigeminal schwannomas (TSs) are rare benign tumors arising from the trigeminal nerve. Gamma Knife radiosurgery (GKS) offers a minimally invasive alternative to surgical resection, but the long-term clinical outco…

[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…

[BACKGROUND] Ultrafine dicing, which reduces cartilage particles to less than 0.2 mm, has gained attention for producing dense implants with reduced distortion. However, concerns about long-term viability and cell damage because of extensiv…

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…

[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…

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…

This study aims to confirm the effectiveness and safety of a prabotulinumtoxin type A (praBTX-A) injection in patients with bruxism and masseter hypertrophy. The study included patients who ground or clenched their teeth while sleeping and …

[BACKGROUND] A 1-2-mm thin rib cartilage graft was used as a septal extension graft to overcome the drawbacks of traditional rib cartilage rhinoplasty, which often results in a stiff nasal tip. The remaining rib cartilage was placed on the …

[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)…

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…

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 …

[BACKGROUND] The efficacy and safety of equine cartilage as a competent xenograft material for rhinoplasty were evaluated and compared to the outcomes of rhinoplasty using silicone implants. [METHODS] We performed a multicenter, double-bli…

[BACKGROUND] Because the tongue consists of 26 intrinsic and extrinsic muscles, even hemiglossectomy, which preserves some of the tongue and its muscles, leads to functional morbidity in speech and swallowing. Subsequent reconstruction usin…

[BACKGROUND] Intended subtotal resection (STR) followed by adjuvant gamma knife radiosurgery (GKRS) has emerged as an effective treatment option for facial nerve (FN) preservation in vestibular schwannomas (VSs). This study aimed to identif…

The nasal aesthetic subunit principle has been widely accepted as the standard for nasal reconstruction with forehead flaps. However, in our experience, one's impression of a reconstructed face can easily be represented by the nose's entire…

[BACKGROUND] A practical application of three-dimensional printing technology has been considered a difficult area in rhinoplasty. However, the patient-specific three-dimensionally printed rhinoplasty guide based on the simulation program t…

[INTRODUCTION] Hump nose in Asians should be managed differently in consideration of the lateral profile and the balance between the dorsal height and nasal tip projection. We suggest an alternative approach comprising mild rasping and nasa…

[OBJECTIVE] The purpose of this study was to investigate changes in the dentoalveolus and occlusal plane associated with the hypotrophy of unilateral masticatory muscles following botulinum toxin (BTX) treatment in the juvenile period of ra…

[BACKGROUND] Misleading advertisements can affect behavior of both consumers and prescribers and may lead to inappropriate use of medications. [OBJECTIVE] To analyze the complaints upheld by regulatory authorities in the United Kingdom, Ca…

[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 …

[BACKGROUND] The septal extension graft is currently the most commonly used primary and secondary rhinoplasty technique in Asia because it provides maximal tip projection and rotational controllability. The authors compared the tip projecti…

[BACKGROUND] A severely crooked nose due to trauma or other causes is difficult to correct. Although various nasal osteotomy techniques have been suggested, satisfactory outcomes have not always been achieved especially in centrally deviate…

[BACKGROUND] Regarding septal fixation in nasal tip plasty, the nasal tip tripod theory may require modification. We performed three-dimensional (3D) photogrammetric analysis of the "Skiff graft," which is a quadripod method involving folde…

As there is no single ideal material for dorsal augmentation in rhinoplasty, there has been a continuing need for the development of improved materials. Therefore, we aimed to evaluate the outcome of using a novel tissue-engineered construc…
