A 2-year Follow-Up of Irradiated Homologous Costal Cartilage Used as a Septal Extension Graft for the Correction of Contracted Nose in Asians

Abstract

The IHCC has the advantages of avoiding donor-site scars, and also provides the same benefits as autogenous costal cartilage. It can therefore be a reliable alternative material for rhinoplasty. A longer follow-up may be necessary to confirm the structural stability of the IHCC graft in the lengthened caudal septum.

Effects of Carving Plane, Level of Harvest, and Oppositional Suturing Techniques on Costal Cartilage Warping

“…2,3,26,32,43,44 Techniques such as irradiation and scoring have failed the test of time with regard to warping prevention. 28,[33][34][35][36][37]40,43,[45][46][47] This study reaffirms the intrinsic warping characteristics of costal cartilage grafts at multiple levels of the thoracic cage, regardless of orientation of harvest or oppositional suturing techniques. Also contradicting current dogma that the majority of costal cartilage warping will occur within the first 15 to 30 minutes of harvest, our results reconfirmed that cartilage warping can occur outside of this window (up to 1 month) and likely will continue over time.…”

Nasal tip surgery: nasal lengthening and augmentation in Asian rhinoplasty

“…However, some studies have indicated that IHCC suffers from problems of warping, infection, and infective and non-infective resorption [1]. Issues of its resorption and infection rates have been controversial, with some studies claiming low absorption rates and positive aesthetic results [2][3][4]. In our experience however, a high rate of both infective and non-infective resorption was observed during the use of IHCC in a revision rhinoplasty.…”

“…Alloplastic materials commonly used in facial reconstruction have also been applied to rhinoplasty [4]. Kim et al [5] described using a bio-absorbable mesh sutured with the septal cartilage to reinforce the septal cartilage, providing sufficient strength to maintain the nasal dorsum.…”

Mineralized collagen artificial bone repair material products used for fusing the podarthral joints with internal fixation—a case report

“…The failure rate is not high, but some cases may require additional surgery, and the outcome of podiatric rehabilitation may be affected. With special attention to risk factors and their connection to the principles of prevention and treatment, surgeons care more and more about the major long-term complications, reliable and safe implant, rhythm of resorbability and measures implemented in practice to minimize the sequelae [8, 9]. As a result of these concerns, biomaterials of choice entail attributes of excellent osteoconductivity, biocompatibility and additional properties like radiolucency, antibiosis, free of immunologic rejection, poor thermal conductivity and ability to induce osteanagenesis [10].…”
