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…

[BACKGROUND] Patients with cleft have functional and aesthetic impairment, and typically require several interventions as they grow. Long-term evaluation following a treatment protocol is essential, but such reports on patients with complet…

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…

[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] Extensive nasal defects after resection of a malignancy are a challenge for all plastic surgeons. Nasal composite tissue defects have to be reconstructed with multiple staging surgeries. A paramedian pedicled forehead flap and …

[BACKGROUND] Augmentation rhinoplasty with autologous fat grafting is a useful procedure to meet the demand for facial harmonization in the Asian population. We used this procedure during orthognathic surgery to address inadequate dorsum pr…

Augmentation rhinoplasty is one of the top three anesthetic surgeries in Asia. I-shaped silicone-polytetrafluoroethylene composite implants are feasible for both primary and secondary augmentation rhinoplasty in Asians. This series was to a…

[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…

[BACKGROUND] The objective of this trial is to evaluate the flexibility of the cartilaginous component of the cleft nose after diced cartilage rhinoplasty by determining the degree of possible bending in relation to the vertical nasal dorsu…

[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. […

[BACKGROUND] Augmentation rhinoplasty had become increasingly popular among Asians. Failure to recognize nasal deviation before surgery may engender unsatisfactory outcomes because the deviation becomes prominently visible after surgery due…

[BACKGROUND] The tumescent face lift uses the concept of subcutaneous cannula lipodissection of the neck, as opposed to wide skin undermining. Lipodissection mobilizes soft tissue while preserving perforating neurovascular branches. The pur…

[BACKGROUND] Since 2012, the senior author has incorporated the natural curvature of rib cartilage as an alar rim graft in addition to the diced cartilage technique for unilateral cleft rhinoplasty. The aim of this study is to describe this…

[BACKGROUND] Augmentative forehead contouring to create a full rounded smooth forehead is increasingly popular worldwide especially in East Asia where a flat and/or concave irregular forehead is considered unaesthetic. We present our outcom…

[INTRODUCTION] Botulinum neurotoxin A (BoNT-A) is a minimally invasive and technically straightforward treatment of masseter muscle (MM) volume reduction and facial contouring, but the literature on its long-term effect on MM volume remains…

[BACKGROUND] The follicular unit transplantation strip harvesting surgery is one of the gold standard methods of hair transplantation; the counting follicular unit ratio and hair density is a major step in donor site evaluation. [AIMS] We …

[BACKGROUND] Silicone-polytetrafluoroethylene composite implants are fast gaining popularity in Asian rhinoplasty. Nonetheless, implant displacement, erythematous reactions, and infections still occur in the authors' patient group during lo…

[BACKGROUND] The perioral region is the most dynamic anatomic area of the face and subject to complex and dramatic changes during aging. Successful treatment for perioral rejuvenation has yet to be identified, and prior studies have reporte…

[BACKGROUND] Silicone and Gore-Tex implants are mainstays of Asian rhinoplasty. Silicone implants are inexpensive and wieldy, but may elicit a foreign-body reaction and are prone to migration. Gore-Tex implants are more biocompatible and ca…

[BACKGROUND] Defects of the nasal ala and upper lip aesthetic subunits can be challenging to reconstruct when they occur in isolation. When defects incorporate both the subunits, the challenge is compounded as subunit boundaries also requir…

[PURPOSE] To determine the graft retention rate of fat injection rhinoplasty in the nasal dorsum region using 3dMD System. [MATERIALS AND METHODS] Thirteen consecutive patients (12 women and 1 man) treated by the corresponding author (F.C.…

[BACKGROUND] Since 2006, the authors have explored the option of using septal cartilage as an alar rim graft on the cleft side during primary rhinoplasty to improve nasal symmetry. The aim of this study was to compare the nasal shape with o…

[BACKGROUND] U.S. Food and Drug Administration-approved formulations of botulinum toxin include onabotulinumtoxinA (Botox; Allergan, Inc., Irvine, Calif.), abobotulinumtoxinA (Dysport; Galderma Pharma S.A., Lausanne, Switzerland), and incob…

[BACKGROUND] There are numerous methods of assessing patient satisfaction with botulinum toxin type A neuromodulation of the glabellar rhytids. As the use of aesthetic neuromodulation increases both in breadth and number of procedures, ther…

[BACKGROUND] Donor site scarring after forehead flap nasal reconstruction is acceptable. However, as aesthetic outcomes standards for cosmetic and reconstructive surgery merge, we aim to enhance results. We recently demonstrated the cosmeti…

[BACKGROUND] Lower face aesthetic contouring is in high demand among Asians with wide and short faces desiring a slim lower face. For this purpose invasive mandible angle reduction and genioplasty are complex procedures with significant ris…

Septal cartilage is deficient in Asians seeking augmentation rhinoplasty. Economized utilization of resources is necessary for durable tip enhancement that complements a dorsal implant. We introduce a modified tongue-in-groove method design…

Diced cartilage graft wrapped in Surgicel or fascia has been widely reported in the literature. Pure diced cartilage graft without the use of a "sleeve," on the contrary, is not as commonly reported. This could be due to concerns of graft d…
