    目的:比较有或没有软骨膜缝合的下鼓膜成形术的移植成功率和听力结果,修复慢性大中央干性穿孔时的移植物穿孔边缘。
    方法:随机对照试验。
    方法:慢性大中央干性穿孔被随机分为褶皱软骨膜移植衬垫(TPGU)和无褶皱软骨膜移植衬垫(NTPG)组。比较两组术后12个月的移植效果和并发症。
    结果:总计,包括61例中央大干性穿孔患者。所有患者均完成12个月随访。残余穿孔发生在TPGU组的0.0%和NTPG组的12.9%(P=0.129),两组分别有0.0%和3.2%的患者在6个月内再次穿孔,分别为(P=0.987)。移植成功率分别为100.0%(30/30)和83.9%(26/31)(P=0.067)。术前(P=0.547)或术后(P=0.612)的空骨间隙(ABG)或平均ABG增益(P=0.597)均无统计学差异。随访期间两组均未观察到移植物相关并发症。没有患者表现出明显的移植物钝化或中介化;NTPG组的一名患者注意到移植物偏侧化。
    结论:在修复大的中央干性穿孔时,与软骨推入技术相比,在下鼓膜成形术中进行内窥镜软骨弯曲,可以提高移植成功率;但是,两组的听力改善情况相当.
    OBJECTIVE: To compare the graft success rates and hearing outcomes of underlay myringoplasty with or without perichondrium tucking of the attached perichondrium, graft perforation margins when repairing chronic large central dry perforations.
    METHODS: Randomized controlled trial.
    METHODS: Chronic large central dry perforations were prospectively randomized to tucking perichondrium graft underlay (TPGU) and no-tucking perichondrium graft underlay (NTPG) groups. The graft outcomes and complications were compared between the two groups at 12 months postoperatively.
    RESULTS: In total, 61 patients with large central dry perforations were included. All patients completed 12-month follow-ups. Residual perforations occurred in 0.0 % of the TPGU group and in 12.9 % of the NTPG group (P = 0.129), and re-perforations occurred within 6 months in 0.0 % and 3.2 % of the two groups, respectively (P = 0.987). The graft success rates were 100.0 % (30/30) and 83.9 % (26/31) (P = 0.067). No significant between-group differences were observed in terms of preoperative (P = 0.547) or postoperative (P = 0.612) air bone gaps (ABGs) or mean ABG gains (P = 0.597). No graft-related complications were observed in either group during follow-up. No patients exhibited significant graft blunting or medialization; graft lateralization was noted in one patient of the NTPG group.
    CONCLUSIONS: Endoscopic cartilage with tucking of the attached perichondrium perforation margins during underlay myringoplasty may improve the graft success rate compared to that of the cartilage push-through technique when repairing large central dry perforations; however, the hearing improvements were comparable in the two groups.

    BACKGROUND: Correction of asymmetry and irregularity deformities with autologous grafts, without osteotomies, offers advantages to both plastic surgeons and patients with severe deviation. Various autologous tissues such as fat, bone, and cartilage grafts are viable options for this purpose.
    OBJECTIVE: This study aimed to compare the efficacy of 3 autologous filling materials in patients with bone asymmetry.
    METHODS: A retrospective evaluation was conducted on 297 patients seeking aesthetic nose surgery between 2015 and 2022. Only primary patients without prior surgery and those with bone asymmetry from trauma, with dorsum protrusion <3 mm, and without osteotomy were included. Patients were divided into fat, cartilage, and bone groups. Grafts were applied to the concave side during closed rhinoplasty, and evaluations were done 12 months after surgery by blinded plastic surgeons and patients using established assessment tools.
    RESULTS: Fat, cartilage, and bone grafts were utilized in 74, 127, and 96 patients, respectively, with a mean follow-up of 19 months. The mean graft volumes were 1.0 cc (bone), 1.3 cc (cartilage), and 1.6 cc (fat). The patient self-assessment scores were 75%, 84.9%, and 86.6%, respectively. The Asher-McDade averages were 77.2%, 86.7%, and 88.4%, respectively. Cartilage and bone graft results were statistically similar in patients\' self-evaluation and significantly higher than those of fat grafts. Blinded assessments showed no significant difference between the cartilage and bone groups.
    CONCLUSIONS: Placing autologous grafts on the concave side for patients with minimal nasal bone protrusion (<3 mm) yields successful results. Cartilage grafts offer advantages in volume, result estimation, and preparation time, making them suitable for larger patient cohorts.

    BACKGROUND: Facial balance significantly impacts aesthetics, particularly in the middle and lower thirds. Patients with chin retrusion often benefit from sagittal plane chin advancement in rhinoplasty, enhancing surgical outcomes and satisfaction.
    OBJECTIVE: This article presents a method for analyzing chin deformities and discusses a hybrid treatment approach to harmonize facial features, complementing rhinoplasty.
    METHODS: The chin positions of patients treated by the senior author were assessed. A retrospective analysis included 49 patients with chin retrusion of 2.5-6 mm. Among them, 22 patients initially offered chin implants declined, leading to planned chin augmentation. Fat grafting was exclusively performed for 20 patients lacking sufficient cartilage. The \"Hybrid Chin Advancement\" technique involved supporting tissues beneath muscles with nasal septum cartilage and fat injections and tissues above muscles with fat injection alone.
    RESULTS: Pre- and postoperative Legan angle measurements and chin advancements were compared across three groups. While preoperative Legan angles were statistically similar, postoperative Legan angles and advancement changes were significantly higher in the implant group (p < 0.0001). Comparing hybrid chin advancement and fat grafting groups, postoperative Legan angles and advancement changes were significantly higher in the hybrid chin group (p < 0.0001).
    CONCLUSIONS: Fat grafting suffices for mild advancements (~ 2 mm), while the hybrid chin method is effective for moderate advancements (~ 4 mm). For advancements exceeding 6 mm, implants or osseous genioplasty are optimal. Our study\'s hybrid approach offers an easy, safe, and reliable method for achieving facial harmony in the lower two-thirds without compromising patient expectations.
    METHODS: This journal requires that authors assign a level of evidence to each article. For a full description of these Evidence-Based Medicine ratings, please refer to the Table of Contents or the online Instructions to Authors www.springer.com/00266 .

    目的:穿孔边缘的修剪和外耳道(EAC)的填塞是修复慢性穿孔的基础方法。这项研究的目的是比较手术时间,移植结果,听力改善,以及在儿童中有或没有修剪穿孔边缘和EAC填塞的情况下内窥镜软骨下膜成形术的并发症。
    方法:前瞻性,随机研究。
    方法:三级转诊中心。
    方法:将12岁以上慢性穿孔的小儿患者随机分为两组:穿孔切缘和EAC填塞(TPME)组或不穿孔切缘和EAC填塞(NTPME)组。操作时间,移植成功率,听力改善,比较两组并发症发生情况。
    结果:52名患者最终被纳入研究。TPME组平均手术时间为31.4±4.2min,NTPME组平均手术时间为23.6±1.7min,差异有统计学意义(P<0.01)。TPME组和NTPME组的听觉饱满度率显着差异(P=0.000)。所有参与者均随访12个月;两组之间的移植成功率没有显着差异(88.5%vs.96.2%;P=0.603)。没有患者发生粘连性中耳炎。在术前和术后测量之间,TPME组的平均气-骨间隙改善了10.2±2.8dB,NTPME组的平均气-骨间隙改善了11.6±0.7dB;这在两组中是显著的(P<0.001)。
    结论:与TPME技术相比,内窥镜软骨下膜鼓膜成形术NTPME缩短了手术时间,避免了听觉饱胀和EAC不适;但是,两种修复儿童大穿孔的技术在移植成功率和听力改善方面具有可比性。
    OBJECTIVE: Trimming of perforation margins and external auditory canal (EAC) packing are basic procedures in underlay myringoplasty for repairing chronic perforations. The objective of this study was to compare the operation time, graft outcome, hearing improvement, and complications of endoscopic cartilage underlay myringoplasty with and without trimming of perforation margins and EAC packing in children.
    METHODS: Prospective, randomized study.
    METHODS: Tertiary referral center.
    METHODS: Pediatric patients older than 12 years with chronic perforations were randomly divided into two groups: myringoplasty with trimming of perforation margin and EAC packing (TPME) group or no trimming of perforation margin and EAC packing (NTPME) group. The operation time, graft success rate, hearing improvement, and complications were compared between the two groups.
    RESULTS: Fifty-two patients were ultimately included in the study. The mean operation time was 31.4 ± 4.2 min in the TPME group and 23.6 ± 1.7 min in the NTPME group; the difference was significant (P < 0.01). The rate of aural fullness significantly differed between the TPME and NTPME groups (P = 0.000). All participants were followed up for 12 months; the graft success rate did not significantly differ between the groups (88.5% vs. 96.2%; P = 0.603). No patients developed adhesive otitis media. Between the preoperative and postoperative measurements, the mean air-bone gap improved by 10.2 ± 2.8 dB in the TPME group and 11.6 ± 0.7 dB in the NTPME group; this was significant (P < 0.001) in both groups.
    CONCLUSIONS: Endoscopic cartilage underlay myringoplasty NTPME shorted the operation time and avoided aural fullness and EAC discomfort compared with the TPME technique; however, graft success and hearing improvement were comparable between the two techniques for repairing large perforations in children.

    目的:本研究的目的是通过内窥镜评估软骨膜成形术后的移植物愈合过程和移植物成功率,不修剪穿孔边缘或外耳道(EAC)包装。材料和方法:慢性鼓膜(TM)穿孔的患者接受内窥镜软骨下鼓膜成形术,无修整穿孔余量或EAC包装。术后6个月评估软骨移植物的愈合过程和移植成功率。结果:本研究包括58只耳朵。术后1周,在中小型穿孔中观察到移植物的临床吻合和新生血管形成,但不在大或小计穿孔中。术后2周,在中小型穿孔中完成了移植物临床吻合和新生血管形成;然而,移植物的新血管形成仅在大穿孔中刚刚开始。术后3周,58耳中的57耳完成了移植物临床吻合。术后4周,在所有穿孔中都实现了完整的新生血管形成。58只耳朵中,术后感染导致1耳残余穿孔,移植物不足导致大穿孔残留穿孔,无感染。总的来说,移植成功率为96.6%(56/58)。移植物成功率与移植物新生血管形成评分之间没有相关性。结论:移植物愈合过程经历了残余TM血管的扩张,移植物临床吻合,在不修剪穿孔边缘和EAC填塞的情况下进行软骨鼓膜成形术和新生血管形成;然而,移植成功率与内镜下移植血管新生评分无关.
    Objective: The objective of this study was to endoscopically evaluate the graft healing process and graft success rate following cartilage myringoplasty, without trimming of the perforation margin or external ear canal (EAC) packing. Material and Methods: Patients with chronic tympanic membrane (TM) perforation underwent endoscope cartilage underlay myringoplasty, without trimming perforation margin or EAC packing. The healing process of the cartilage graft and the graft success rate were evaluated at 6 months postoperatively. Results: Fifty-eight ears were included in this study. At 1 week postoperatively, clinical inosculation and neovascularization of the graft were observed in small- and medium-sized perforations, but not in large or subtotal perforations. At 2 weeks postoperatively, graft clinical inosculation and neovascularization were completed in the small- and medium-sized perforations; however, neovascularization of the graft had only just begun in the large perforations. At 3 weeks postoperatively, completion of the graft clinical inosculation was achieved in 57 of the 58 ears. At 4 weeks postoperatively, complete neovascularization was achieved in all perforations. Of the 58 ears, postoperative infection resulted in residual perforation in 1 ear, and an insufficient graft resulted in residual perforation in a large perforation without infection. Overall, the graft success rate was 96.6% (56/58). There was no correlation between the graft success rate and graft neovascularization score. Conclusions: The graft healing process experienced the dilation of the blood vessels of the remnant TM, graft clinical inosculation, and neovascularization following cartilage myringoplasty without trimming of the perforation margin and EAC packing; however, the graft success rate was not related to the endoscopic graft neovascularization scores.

    目的:探讨喉气管重建(LTR)后影响移植物愈合的因素。
    方法:我们在阿卜杜勒阿齐兹国王大学医院进行了回顾性图表回顾,利雅得,沙特阿拉伯,2008年1月至2023年10月。我们纳入了所有接受LTR并需要前和/或后移植的患者,而那些在没有移植的情况下接受手术的人和那些信息不完整的人被排除在外。
    结果:分析了49例患者。大多数患者是儿科(65.3%),男性(65.3%),没有共存的合并症(55.1%),并有3-4级狭窄(59.2%)。30例(61.2%)患者接受了开放手术。发生各种移植物并发症,包括感染(n=1,2%),开裂(n=3,6.1%),疤痕(n=6,12.2%),和颗粒化(n=29,59.2%)。只有15例患者(30.65%)达到了“健康”移植物的复合状态。在43例术后培养的患者中,在10例和4例患者中观察到铜绿假单胞菌和耐甲氧西林金黄色葡萄球菌的阳性结果,分别。开放手术和双阶段手术与较高的肉芽组织形成率显着相关。与成人年龄组相比,儿科年龄组的完全上皮形成率明显更高。有不健康移植物的患者中有相当大的比例进行了开放手术。与健康移植物相比,不健康移植物的双阶段LTR率明显更高。延长的支架持续时间与各种移植物相关的并发症有关。多因素logistic回归分析显示,各种因素与术后移植物相关并发症之间无统计学意义。
    结论:开腹手术,双阶段程序,儿科年龄组,在多因素分析中,在LTR期间,支架和支架持续时间不是与术后移植物相关并发症相关的显著危险因素.
    OBJECTIVE: To examine the factors that affect graft healing after laryngotracheal reconstruction (LTR).
    METHODS: We conducted a retrospective chart review at King Abdulaziz University Hospital, Riyadh, Saudi Arabia, between January-2008 and October-2023. We included all patients who underwent LTR and required anterior and/or posterior graft placement, while those who underwent procedures without graft placement and those with incomplete information were excluded.
    RESULTS: Forty-nine patients were analyzed. Most patients were pediatric (65.3%), male (65.3%), had no coexisting comorbidities (55.1%), and harbored grade 3-4 stenosis (59.2%). Thirty patients (61.2%) underwent open surgery. Various graft complications occurred including infection (n = 1, 2%), dehiscence (n = 3, 6.1%), scar (n = 6, 12.2%), and granulation (n = 29, 59.2%). Only 15 patients (30.65%) achieved the composite status of \"healthy\" graft. Among 43 patients who had postoperative cultures, positive results for Pseudomonas aeruginosa and methicillin-resistant Staphylococcus aureus were observed in 10 and four patients, respectively. Open surgery and double-stage procedure were significantly associated with higher rates of granulation tissue formation. Pediatric-age group had significantly higher rate of complete epithelization compared to adult-age group. A significantly greater proportion of patients who had unhealthy grafts had open surgery. The rate of double-stage LTR was significantly higher in unhealthy grafts compared to healthy grafts. Prolonged stent duration was linked to various graft-related complications. Multivariate logistic regression analyses showed no statistically significant correlations between various factors and postoperative graft-related complications.
    CONCLUSIONS: Open surgery, double-stage procedure, pediatric age group, and stent duration were not significant risk factors associated with postoperative graft-related complications during LTR in multivariate analysis.

    目的:本项目的目标是开发和验证一种针对患者的,使用磁共振成像(MRI)数据和3维(3D)打印技术进行软骨修复的解剖学正确移植物。具体目的是测试3D打印和个性化植入的新方法的准确性,解剖学形状的生物支架,用于治疗人类尸体模型中的软骨缺损。我们假设个性化,与普通的扁平支架相比,根据MRI数据设计的解剖3D打印支架将为大型软骨缺损提供更优化的填充。
    方法:在配对的人尸体膝盖中产生了四种局灶性软骨缺损(FCD),年龄<40岁,在股骨内侧髁(MFC)的承重表面,股骨外侧髁(LFC),髌骨,和每个膝盖的滑车。获得MRI,作为实验组,设计并3D打印了左膝的解剖移植物,和作为对照组的右膝通用扁平移植物。将移植物植入相应的缺损中并使用组织粘合剂固定。获得重复的植入后MRI。移植物脱离测量为移植物表面和天然软骨表面之间在垂直于软骨下骨的方向上的距离(mm)。移植物轮廓被测量为移植物的下表面和软骨下骨之间在垂直于关节表面的方向上的间隙。
    结果:与MFC中的通用移植物相比,解剖移植物的移植物台阶在统计学上明显更好(0.0±0.2mmvs.0.7±0.5mm,p<0.001),LFC(0.1±0.3mmvs.1.0±0.2mm,p<0.001),髌骨(-0.2±0.3mmvs.-1.2±0.4mm,p<0.001),和滑车(-0.4±0.3vs.0.4±0.7,p=0.003)。LFC中解剖移植物的移植物轮廓在统计学上显着更好(0.0±0.0mm与0.2±0.4mm,p=0.022)和滑车(0.0±0.0mmvs.1.4±0.7mm,p<0.001)。解剖移植物观察到的最大步距为-0.9mm,最大轮廓不匹配为0.8mm。
    结论:这项研究验证了使用MRI和3D打印技术制造解剖学上精确的软骨移植物的过程。与普通的扁平移植物相比,解剖移植物表现出更好的贴合性。

    OBJECTIVE: The goal of this project was to develop and validate a patient-specific, anatomically correct graft for cartilage restoration using magnetic resonance imaging (MRI) data and 3-dimensional (3D) printing technology. The specific aim was to test the accuracy of a novel method for 3D printing and implanting individualized, anatomically shaped bio-scaffolds to treat cartilage defects in a human cadaveric model. We hypothesized that an individualized, anatomic 3D-printed scaffold designed from MRI data would provide a more optimal fill for a large cartilage defect compared to a generic flat scaffold.
    METHODS: Four focal cartilage defects (FCDs) were created in paired human cadaver knees, age <40 years, in the weight-bearing surfaces of the medial femoral condyle (MFC), lateral femoral condyle (LFC), patella, and trochlea of each knee. MRIs were obtained, anatomic grafts were designed and 3D printed for the left knee as an experimental group, and generic flat grafts for the right knee as a control group. Grafts were implanted into corresponding defects and fixed using tissue adhesive. Repeat post-implant MRIs were obtained. Graft step-off was measured as the distance in mm between the surface of the graft and the native cartilage surface in a direction perpendicular to the subchondral bone. Graft contour was measured as the gap between the undersurface of the graft and the subchondral bone in a direction perpendicular to the joint surface.
    RESULTS: Graft step-off was statistically significantly better for the anatomic grafts compared to the generic grafts in the MFC (0.0 ​± ​0.2 ​mm vs. 0.7 ​± ​0.5 ​mm, p ​< ​0.001), LFC (0.1 ​± ​0.3 ​mm vs. 1.0 ​± ​0.2 ​mm, p ​< ​0.001), patella (-0.2 ​± ​0.3 ​mm vs. -1.2 ​± ​0.4 ​mm, p ​< ​0.001), and trochlea (-0.4 ​± ​0.3 vs. 0.4 ​± ​0.7, p ​= ​0.003). Graft contour was statistically significantly better for the anatomic grafts in the LFC (0.0 ​± ​0.0 ​mm vs. 0.2 ​± ​0.4 ​mm, p ​= ​0.022) and trochlea (0.0 ​± ​0.0 ​mm vs. 1.4 ​± ​0.7 ​mm, p ​< ​0.001). The anatomic grafts had an observed maximum step-off of -0.9 ​mm and a maximum contour mismatch of 0.8 ​mm.
    CONCLUSIONS: This study validates a process designed to fabricate anatomically accurate cartilage grafts using MRI and 3D printing technology. Anatomic grafts demonstrated superior fit compared to generic flat grafts.
    METHODS: Level IV.

    METHODS: Prospective case series.
    METHODS: The study enrolled patients with large marginal perforations who underwent endoscopic cartilage myringoplasty with the inside-out raising mucosal-tympanomeatal flap technique. The graft success rate, hearing outcomes, and complications were evaluated at 12 months postoperatively.
    RESULTS: In total, 48 patients with large marginal perforations were included. 81% of the population had large perforation, 14.6 had subtotal and total perforation was seen in 4.2%. The mean operation time was 38.6 ± 7.1 min. At 12 months postoperatively, the graft success rate was 89.6% (43/48). The mean air-bone gap was 25.6 ± 5.2 dB preoperatively and 16.5 ± 4.1 dB at 12 months postoperatively, with significant differences between these values (p = 0.001). The functional success rate was 85.4% (41/48). None of the patients experienced worsened sensorineural hearing loss or graft-related complications, such as graft lateralization, significant blunting, and graft medialization, during follow-up.
    CONCLUSIONS: Endoscopic cartilage-perichondrium myringoplasty for the repair of large marginal perforations using the inside-out raising mucosal-tympanomeatal flap technique was associated with satisfactory graft outcomes and minimal complications.

  • 文章类型: Randomized Controlled Trial
    目的:本研究的目的是比较两种内窥镜软骨膜-软骨移植技术修复大穿孔的移植效果和并发症。
    方法:单中心盲法随机对照试验。
    方法:前瞻性随机将61个TM面积超过50%的大穿孔随机分为游离软骨膜和游离软骨移植组(FPFC,n=31)或软骨膜部分附着软骨移植组(PPAC,n=30)。主要结局指标是手术时间;次要结局指标是移植成功率和术后12个月的听力增益以及术后并发症。
    结果:所有患者均完成12个月的随访。FPFC组平均手术时间为38.2±2.3min,PPAC组为37.4±5.6min(P=0.658)。术后3个月,FPFC组和PPAC组的移植成功率分别为96.7%和93.3%(P=0.976).术后12个月,移植成功率FPFC组为96.7%,PPAC组为83.3%(P=0.182).然而,FPFC组和PPAC组的残留和无感染的再穿孔率为0.0%(0/31),PPAC组为16.7%(5/30)(P=0.056)。术前(P=0.842)或术后(P=0.759)未观察到组间差异(P=0.886)。然而,在FPFC组和PPAC组中,分别有6.5%和3.3%的患者出现了颗粒性心肌炎.
    结论:这项研究表明,12个月的移植成功率和听力增益在软骨游离和部分附着软骨移植技术之间具有可比性,然而,部分附着技术可能会增加残余和重新穿孔。
    OBJECTIVE: The objective of this study was to compare the graft outcomes and complications of two endoscopic perichondrium-cartilage graft techniques for repairing large perforations.
    METHODS: Single center blinded randomized controlled trial.
    METHODS: 61 large perforations more than 50% of TM area were prospectively randomized to undergo the free perichondrium and free cartilage graft group (FPFC, n = 31) or perichondrium partial attachment the cartilage graft group (PPAC, n = 30). The primary outcome measures were the operation time; secondary outcome measures were the graft success rate and hearing gain at 12 months postoperatively and postoperative complications.
    RESULTS: All patients completed follow-up of 12 months. The mean operation time was 38.2 ± 2.3 min in the FPFC group and 37.4 ± 5.6 min in the PPAC group (P = 0.658). At postoperative 3 months, the graft success rates were 96.7% in the FPFC group and 93.3% in the PPAC group (P = 0.976). At postoperative 12 months, the graft success rates were 96.7% in the FPFC group and 83.3% in the PPAC group (P = 0.182). However, the residual and re-perforation rate with no infection was 0.0% (0/31) in the FPFC group and 16.7% (5/30) in the PPAC group (P = 0.056). No significant between-group differences were observed pre- (P = 0.842) or post- (P = 0.759) operative air bone gap (ABG) values or mean ABG gain (P = 0.886). However, granular myringitis has been noted in 6.5% in the FPFC group and in 3.3% in the PPAC group.
    CONCLUSIONS: This study suggested that 12-month graft success and hearing gain were comparable between the perichondrium free and partial attachment the cartilage graft techniques, nevertheless, partial attachment technique could increase residual and re-perforations.
