To assess the clinical outcome of crushed cartilage grafts used to conceal contour irregularities in rhinoplasty.
We reviewed the medical records of 462 patients in whom crushed autogenous cartilage grafts were used, selected from a total of 669 patients in whom rhinoplasty procedures were performed at our institution between June 1, 1999, and June 1, 2006. The grafts were used as slightly, moderately, significantly, or severely crushed.
Eight hundred nine cartilage grafts (41 slightly crushed grafts [5%], 650 moderately crushed grafts [80%], and 118 significantly crushed grafts [15%]) were used in 462 patients. Resorption occurred in 11 of the 462 patients (2.4%). All of the resorbed grafts (6 moderately crushed grafts and 5 significantly crushed grafts) had been placed in the dorsal area. The resorption rate of those grafts was lower in the moderately crushed cartilage grafts (6 of 284 grafts [2.1%]) than in the significantly crushed grafts (5 of 38 grafts [13.1%]). There was no resorption of slightly crushed grafts.
The degree of crushing applied is important for long-term clinical outcome of autogenous crushed cartilage grafts. Slight or moderate crushing of cartilage creates an outstanding graft material for concealing irregularities and provides both excellent long-term clinical outcome and predictable esthetic results.
评估用于掩饰鼻整形术中轮廓不规则的碎软骨移植的临床效果。
我们回顾了462例使用自体碎软骨移植患者的病历，这些患者选自1999年6月1日至2006年6月1日在我院接受鼻整形手术的669例患者。移植的软骨被轻度、中度、重度或极重度粉碎。
462例患者共使用了809块软骨移植（41块轻度粉碎移植[5%]，650块中度粉碎移植[80%]，118块重度粉碎移植[15%]）。462例患者中有11例（2.4%）发生了移植吸收。所有吸收的移植（6块中度粉碎移植和5块重度粉碎移植）均放置在鼻背区域。中度粉碎软骨移植的吸收发生率（284块移植中有6块[2.1%]）低于重度粉碎移植（38块移植中有5块[13.1%]）。轻度粉碎移植未发生吸收。
粉碎程度对自体碎软骨移植的长期临床效果很重要。轻度或中度粉碎软骨可形成用于掩饰不规则的优质移植材料，并提供良好的长期临床效果和可预测的美学效果。
