Autologous costal cartilage graft is optimal for augmentation rhinoplasty but with complications including markedly visible graft margins and dorsal contour irregularities. Therefore, the authors introduced the diced costal cartilage graft to smoothen the margins of bilateral spreader graft for nasal dorsum augmentation. A total of 6 patients were recruited for this augmentation rhinoplasty. The pre- and postoperative photographs were taken for improvement evaluation. During a mean follow-up of 15 months, none of the patients developed major complications that may require removal or revision of the costal cartilage grafts. Five patients (80%) were very satisfied with the aesthetic outcome. This simple algorithm facilitates the substantial augmentation and removes the visibility of dorsal graft in the costal cartilage rhinoplasty for the East Asian population.

Comparative analysis of small-incision and traditional techniques in costal cartilage harvesting: Outcomes on thoracic deformities and scar appearance.

Objective: This study aims to compare the postoperative thoracic deformity and scar aesthetic outcomes of auricular reconstruction between the conventional large-incision technique and small-incision technique with perichondrium preservation for costal cartilage harvesting.
Methods: A retrospective analysis was performed on 134 patients who underwent auricular reconstruction using tissue expanders and autologous costal cartilage harvested from the right chest wall between January 2021 and September 2023. Patients were divided into two groups according to the harvesting technique: the traditional large-incision group (n = 64) and the small-incision group with perichondrium preservation (n = 70).

Irradiated Homologous Costal Cartilage Grafts in Complex Functional Septorhinoplasty.

Optimal results in complex nasal reconstruction, particularly in the context of post-traumatic and revision septorhinoplasty, often require the use of cartilage grafts to provide additional structural support to the nose. While autologous costal cartilage (ACC) has been traditionally used, this can be limited by donor site morbidity, increased operative time, and in some cases, lack of suitable cartilage for grafting. There has been a trend towards using irradiated homologous costal cartilage (IHCC) as an alternative source of graft material.

Background: The septum is often underdeveloped in East Asian populations, and traditional endogenous extension stents may not adequately fulfill the requirements for rhinoplasty. Herein, we present an innovative exogenous extension framework featuring a mortise and tenon structure specifically designed for East Asians.
Methods: This framework comprises a mushroom-shaped rib cartilage component and a lancet-shaped expanded polytetrafluoroethylene (ePTFE) element, which are interconnected through a mortise and tenon design.
Cervical Subcutaneous Emphysema and Pneumomediastinum Following Revision Septorhinoplasty With Autologous Costal Cartilage Graft: A Case Report.

Cervical subcutaneous emphysema and pneumomediastinum without pneumothorax are exceedingly rare complications following rhinoplasty, with limited cases reported in the literature. This report presents a case of revision septorhinoplasty using autologous costal cartilage, where the patient complained of a sore throat 36 hours postoperatively. On physical examination, cervical subcutaneous emphysema was palpated, and radiologic evaluation confirmed both cervical subcutaneous emphysema and pneumomediastinum.
