Augmentation rhinoplasty of the Asian nose may be effectively accomplished with alloplastic materials. However, certain circumstances mandate the use of autologous grafts (e.g., dorsal augmentation that exceeds 8 mm and patient intolerance of alloplastic implants). Septal and auricular cartilages are inadequate for dorsal augmentation of the Asian nose. The(More)
BACKGROUND Columellar defects or deformities are challenging problems to correct. Many different techniques have been described, yet none are ideal, especially for the purpose of aesthetic improvement. METHODS Local flaps are designed from the subnasale region extending into the nasal floor. It is a one-stage procedure that transfers well-matched skin to(More)
The contracted nose is a unique entity that follows primary rhinoplasty in the Asian patient. The proposed reasons for this complication are capsular contraction from a silicone nasal implant, pressure necrosis of the lower lateral cartilage resulting from the nasal implant, and infection after alloplastic implantation. The two principal anatomic(More)
BACKGROUND In augmentation rhinoplasty, delayed morphologic changes are often observed with silicone implants, despite them being known as a safe implant material. The purpose of this study was to identify the cause and time course of delayed shape changes of silicone implants, through the long-term evaluation of inserted implants and their surrounding(More)
OBJECTIVES/HYPOTHESIS Gore-Tex is known to be a relatively safe material. However, it leads to complications. Although widely used, the reasons complications occur are poorly understood. Thus, this study attempted to investigate histological changes between the Gore-Tex, removed within a certain period of time after rhinoplasty, and its neighboring tissues.(More)
IMPORTANCE Augmentation rhinoplasty is common in the Asian population and the lack of suitable autologous material for augmentation has led to the use of alloplastic materials. Many of these patients develop complications, including a depressed dimple-like scar of the nasal tip. Causes of such dimpling include the use of large implants, infection,(More)
Alar vertical discrepancy including alar base has been viewed as one of the most challenging reconstructive problems in rhinoplasty. The authors have created a simple technique that consistently gives aesthetically acceptable results. The authors have designed the seesaw technique to correct alar discrepancy (type 1 to 3). Type 1 has been used in 14(More)
OBJECTIVES/HYPOTHESIS The morphologic features of upper and lower lateral cartilage and septal cartilage of the cadaveric nose were analyzed to provide practical anatomical knowledge for Asian rhinoplasty. STUDY DESIGN Cadaveric dissection. METHODS A total of 21 Korean adult cadavers were dissected. External nasal morphology was observed, measured,(More)
