This study was conducted to compare changes in pharyngeal airway after different orthognathic procedures in subjects with class III deformity. The study included CBCT scans of 48 skeletal class III patients (29 females and 19 males, mean age 23.50 years) who underwent orthognathic surgery in conjunction with orthodontic treatment. The participants were divided into three groups of 16, as follows: Group 1, mandibular setback surgery; group 2, combined mandibular setback and maxillary advancement surgery; and group 3, maxillary advancement surgery. CBCT images were taken 1 day before surgery (T0), 1 day (T1), and 6 months (T2) later. The dimensions of the velopharynx, oropharynx, and hypopharynx were measured in CBCT images. In all groups, there was a significant decrease in airway variables immediately after surgery, with a significant reversal 6 months later (P < 0.05). In subjects who underwent maxillary advancement, the airway dimensions were significantly greater at T2 than the T0 time point (P < 0.05), whereas in the mandibular setback and bimaxillary surgery groups, the T2 values were lower than the baseline examination (P < 0.05). The alterations in airway variables were significantly different between the study groups (P < 0.05). The mandibular setback procedure caused the greatest reduction in the pharyngeal airway, followed by the bimaxillary surgery and maxillary advancement groups, with the latter exhibiting an actual increase in the pharyngeal airway dimensions. It is recommended to prefer a two-jaw operation instead of a mandibular setback alone for correction of the prognathic mandible in subjects with predisposing factors to the development of sleep-disordered breathing.
本研究旨在比较III类畸形患者在不同的正颌手术后咽气道的变化。该研究包括48例骨骼III级患者的CBCT扫描(29名女性和19名男性,平均年龄23.50岁),他们接受了正颌手术和正畸治疗。参与者分为三组,每组16人,分别为:第一组,下颌退缩手术;第2组:下颌后退+上颌前进联合手术;第三组,上颌前移手术。术前1天(T0)、术后1天(T1)、术后6个月(T2)分别取CBCT图像。在CBCT图像中测量腭咽、口咽和下咽的尺寸。两组患者术后气道各项指标均显著下降,6个月后出现显著逆转(P < 0.05)。上颌前进组患者T2时气道尺寸明显大于T0时(P < 0.05),而下颌骨后退组和双颌手术组患者T2值低于基线检查(P < 0.05)。两组间气道变量变化差异有统计学意义(P < 0.05)。下颌后退手术导致咽气道最大的缩小,其次是双颌手术组和上颌推进组,后者显示出咽气道尺寸的实际增加。对于有睡眠呼吸障碍易感因素的患者,建议采用双颌手术而不是单独的下颌骨退缩来矫正下颌骨前突。

Most head and neck infections originate from odontogenic causes; therefore, it is important to determine the severity of odontogenic infections. Since severe infection can cause sepsis, a systemic examination should be performed when evaluating a patient with odontogenic infection. C-reactive protein (CRP), white blood cell count (WBC), procalcitonin (PCT), and presepsin (PSEP) can be used to evaluate the severity of inflammatory status and sepsis in patients in the early stages of visiting the emergency room. Moreover, sepsis can be diagnosed based on the systemic inflammatory response syndrome (SIRS) classification. In relation to PSEP, significant study results on sepsis have been reported in other organ infections. However, there has been no progress in odontogenic infection; therefore, this study aimed to determine the diagnostic value of sepsis derived from odontogenic infection. This study was conducted from March 2021 to October 2021 on 43 patients admitted to the Department of Oral and Maxillofacial Surgery, Dankook University Hospital, in the emergency room for odontogenic infection. All patients underwent vital sign assessment and diagnostic tests (CRP, WBC, PCT, PSEP) in the emergency room. Sepsis was classified according to the SIRS criteria, and CRP, WBC, PCT, and PSEP levels were measured. The Statistical Package for the Social Sciences was used for statistical analyses. The results of this study showed a moderately positive correlation between CRP and PCT, CRP and PSEP, and CT and PSEP levels. In addition, PCT and PSEP levels showed a positive correlation with sepsis. The odds ratios of sepsis and PCT and sepsis and PSEP were statistically significant. The optimal cut-off values obtained through the receiver operating characteristic curve were 0.24 and 671.5 for PCT and PSEP, respectively. Finally, there were positive correlations between CRP level and length of stay, WBC and Flynn scores, PCT level and Flynn scores, PCT level and length of stay, and PSEP level and length of stay. WBC and CRP and PCT levels have been used in the past to determine the severity of infection and sepsis in patients with odontogenic infection, but PSEP was also found to have diagnostic value in this study. According to this study, a PSEP level of 671.5 pg/ml or higher for odontogenic infection can be considered an abnormal level.
大多数头颈部感染源于牙源性原因;因此,确定牙源性感染的严重程度非常重要。由于严重感染可导致败血症,因此在评估牙源性感染患者时应进行全身检查。c反应蛋白(CRP)、白细胞计数(WBC)、降钙素原(PCT)和脓毒素(PSEP)可用于评估急诊早期患者炎症状态和脓毒症的严重程度。此外,脓毒症可以根据系统性炎症反应综合征(SIRS)分类进行诊断。关于PSEP,其他器官感染的脓毒症的重要研究结果已被报道。然而,在牙源性感染方面没有任何进展;因此,本研究旨在探讨牙源性感染脓毒症的诊断价值。该研究于2021年3月至2021年10月对檀国大学医院口腔颌面外科急诊室因牙源性感染入院的43名患者进行了研究。所有患者均在急诊室接受生命体征评估和诊断检测(CRP、WBC、PCT、psp)。根据SIRS标准对脓毒症进行分类,并测量CRP、WBC、PCT和psp水平。社会科学统计资料包用于统计分析。本研究结果显示CRP与PCT、CRP与PSEP、CT与PSEP水平呈中度正相关。PCT和PSEP水平与脓毒症呈正相关。脓毒症与PCT、脓毒症与psp的比值比均有统计学意义。PCT和psp通过受试者工作特征曲线获得的最佳截止值分别为0.24和671.5。最后,CRP水平与住院时间、WBC与Flynn评分、PCT水平与Flynn评分、PCT水平与住院时间、psp水平与住院时间呈正相关。WBC、CRP和PCT水平过去被用于判断牙源性感染患者感染和败血症的严重程度,但在本研究中发现psp也具有诊断价值。根据本研究,牙源性感染的psp水平为671.5 pg/ml或更高可视为异常水平。

In terms of a highly atrophic maxilla, bone augmentation still remains very challenging. With the introduction of computer-aided design/computer-aided manufacturing (CAD/CAM) for allogeneic bone blocks, a new method for the treatment of bone deficiencies was created. This case report demonstrates the successful use of two specially designed and CAD/CAM manufactured allogeneic bone blocks for a full arch reconstruction of a highly atrophic maxilla with an all-on-six concept. We report the case of a 55-year-old male patient with a highly atrophic maxilla and severe bone volume deficiencies in horizontal and vertical lines. In order to treat the defects, the surgeon decided to use a combination of two allogeneic bone blocks and two sinus floor augmentations. The bone blocks were fabricated from the data of a cone beam computed tomography (CBCT) using CAD/CAM technology. After the insertion of the two bone blocks and a healing period of 7 months, six dental implants were placed in terms of an all-on-six concept. The loading of the implants took place after an additional healing time of 7 months with a screw-retained prosthetic construction and with a milled titanium framework with acrylic veneers. The presented procedure shows the importance of the precise design of CAD/CAM manufactured allogeneic bone blocks for the successful treatment of a highly atrophic maxilla. Proper soft-tissue management is one of the key factors to apply this method successfully.
就高度萎缩的上颌骨而言,骨增强术仍然非常具有挑战性。异体骨块的计算机辅助设计/计算机辅助制造(CAD/CAM)技术的引入,为骨缺损的治疗创造了一种新的方法。本病例报告展示了两个特别设计和CAD/CAM制造的同种异体骨块的成功应用,用于高度萎缩的上颌全弓重建。我们报告的情况下,55岁的男性患者高度萎缩的上颌骨和严重的骨量不足,在水平和垂直线。为了治疗缺陷,外科医生决定使用两个异体骨块和两个窦底增强的组合。采用CAD/CAM技术从锥形束计算机断层扫描(CBCT)的数据制作骨块。在植入两个骨块和7个月的愈合期后,按照全-六的概念放置了六颗牙种植体。植入物的加载是在螺钉保留假体结构和磨钛框架与丙烯酸贴面的额外愈合时间7个月后进行的。本研究显示了CAD/CAM制造的同种异体骨块的精确设计对于成功治疗高度萎缩的上颌骨的重要性。正确的软组织处理是该方法成功应用的关键因素之一。

Background: Temporal hollowing is a common complication following the rotation of the temporalis muscle that leaves the patient with a cosmetic impairment. Several alloplastic materials have been used to reconstruct the donor site; however, these implants need meticulous adaptation to conform the periphery of the defect and restore the contour of the temporal area. The aim of this study was to assess the use of patient-specific polyetheretherketone (PEEK) temporal implants to prevent temporal hollowing following the use of full temporalis muscle flap for large maxillary defects reconstruction.

Methods: This was a prospective study conducted on eight patients with major maxillary defects indicating the need of reconstruction with full temporalis muscle flap or any lesion indicating major maxillary resection and immediate reconstruction with total temporalis muscle flap. For each patient, a patient-specific PEEK implant was fabricated using virtual planning and milled from PEEK blocks. In the surgical theater, the temporalis muscle was exposed, elevated, and transferred to the maxilla. After the temporalis muscle transfer, PEEK implants were fixed in place to prevent temporal hollowing.

Results: The surgical procedures were uneventful for all patients. The esthetic result was satisfactory with no post-operative complications except in one patient where seroma occurred after 2 weeks and resolved after serial aspiration.

Conclusion: Patient-specific PEEK implant appears to facilitate the surgical procedures eliminate several meticulous steps that are mainly based on the surgeon's experience.

Trial registration: Clinical trials registration: NCT05240963 .

背景:颞空是颞肌旋转后的常见并发症,给患者留下美观的损害。几种同种异体材料已被用于重建供体部位;然而,这些植入物需要细致的适应,以符合缺损的周围和恢复颞区的轮廓。本研究的目的是评估使用患者特异性聚醚醚酮(PEEK)颞叶种植体来防止颞肌瓣重建上颌大缺损后的颞空穴。方法:本研究是一项前瞻性研究,对8例上颌重大缺损需要全颞肌瓣重建或任何病变需要上颌大切除立即全颞肌瓣重建的患者进行研究。对于每个患者,使用虚拟计划制作患者特定的PEEK植入物,并从PEEK块中铣削。在手术室中,颞肌被暴露、抬高并转移到上颌骨。颞肌转移后,固定PEEK植入物以防止颞空。结果:所有患者手术过程顺利。美观结果令人满意,除1例患者术后2周出现血清肿,经连续抽吸后消退外,无术后并发症。结论:患者特异性PEEK植入物似乎简化了手术过程,消除了主要基于外科医生经验的几个细致步骤。临床试验注册:NCT05240963。

Background: The stability of the results remains a significant concern in orthognathic surgeries. This study aimed to assess the amount of relapse following mandibular advancement with/without maxillomandibular fixation (MMF).

Materials and methods: A single-blind clinical trial was conducted on patients with mandibular retrognathism who underwent BSSO for mandibular advancement and Lefort I maxillary superior repositioning. Patients were randomly divided into two groups of treatment (MMF) and control (no MMF). In the treatment group, MMF was performed for 2 weeks; meanwhile, MMF was not performed in the control group, and only guiding elastics were applied postoperatively. Lateral cephalograms were obtained preoperatively (T1), immediately after surgery (T2), and at 1 year postoperatively (T3). The distance from points A and B to the X and Y plane were measured to identify the amount of vertical and horizontal relapse in 1 year as a primary outcome. An independent t-test was applied in order to find differences in outcomes between the control and treatment groups.

Results: Fifty-eight patients were evaluated in two groups (28 patients in the MMF group and 30 in the no-MMF group). The magnitude of mandibular advancement following BSSO was 7.68±1.39 mm and 7.53±1.28, respectively, without significant difference among the groups (p= 0.68). The mean sagittal and vertical changes (relapse) at point B were significantly different between the two groups at 1-year follow-up after the osteotomy (p=0.001 and p=0.05, respectively).

Conclusion: According to the results of this study, patients with short-term MMF following BSSO for mandibular advancement benefit from significantly greater skeletal stability in the sagittal and vertical dimensions.

背景:在正颌手术中,手术效果的稳定性仍是一个重要问题。本研究旨在评估下颌前移术后使用/不使用上颌下颌固定术(MMF)的复发率:对下颌后突患者进行了单盲临床试验,这些患者接受了下颌前突BSSO手术和Lefort I上颌骨上部复位手术。患者被随机分为治疗组(MMF)和对照组(无 MMF)。治疗组进行为期两周的MMF治疗;而对照组则不进行MMF治疗,术后仅使用引导弹力袜。分别在术前(T1)、术后即刻(T2)和术后一年(T3)拍摄侧位头颅片。测量 A 点和 B 点到 X 平面和 Y 平面的距离,以确定 1 年后垂直和水平方向的复发量作为主要结果。为了发现对照组和治疗组之间的结果差异,采用了独立的 t 检验:58名患者分两组接受了评估(MMF组28人,无MMF组30人)。BSSO术后下颌骨前移的幅度分别为(7.68±1.39)毫米和(7.53±1.28)毫米,两组间无显著差异(P= 0.68)。截骨后随访1年,B点的平均矢状变和垂直变(复发)在两组间有显著差异(分别为P=0.001和P=0.05):根据这项研究的结果,下颌前突BSSO术后短期MMF患者在矢状和垂直方向上的骨骼稳定性明显更强。

Background: Even though dental implants are a reliable choice for dental rehabilitation, implant failures due to various etiologies have been reported. Early implant failures account for 2 to 6% of installed implants and are reported to have a higher rate than late failures, regardless of loading time. We herein report three cases of acute sinusitis and early implant failure with implants that failed within 1 month after installation. The aim of this study was to evaluate the surface properties of early failed implants and peri-implant tissue to determine the early osseointegration pattern in acute sinusitis-related failed implants as well as the possible role of surface contamination in the failure of osseointegration.

Results: A combined histological, electron microscopy, and X-ray spectroscopy approach was used to characterize the surface of non-osseointegrated titanium implants and the surrounding biological tissues. Morphologic scanning electron microscopy revealed a heterogeneous surface and irregular osseointegration. The implant surface was covered mostly by carbon- and oxygen-rich organic matter. Energy-dispersive X-ray spectroscopy surface analysis of three implants showed the incorporation of some contaminants in both the upper and apical regions. Carbon, nitrogen, sodium, silicon, chlorine, sulfur, gold, and zirconium were detected on the surface of one or more failed implants. Fibrosis, lymphocytic, and macrophage infiltrates and a high activation of osteoclasts surrounding the bone graft particles were detected in the surrounding tissues.

Conclusions: The etiology and mechanism of early implant failure, especially in sinus-related cases, as well as the proper management interventions to minimize the rate of early implant failures, are of great concern. No matter how confident and accurate the surgeon's operation, there may be unknown errors in the whole procedure that no one knows about. Rather than errors related to the implant surface, it is expected that there were invisible problems during the evaluation of the patient's own unique sinus mucosal inflammation or the operator's own procedure. Furthermore, well-designed researches are necessary to reveal the effect of material-related factors on acute sinus complication and early implant failure.

背景:尽管种植牙是牙齿康复的可靠选择,但由于各种病因导致的种植失败也时有报道。早期失败的种植体占已安装种植体的 2%-6%,而且无论装载时间长短,早期失败率都高于晚期失败率。我们在此报告了三例急性鼻窦炎和种植体早期失败的病例,这些病例的种植体在安装后 1 个月内失败。本研究的目的是评估早期失败种植体的表面特性和种植体周围组织,以确定急性鼻窦炎相关失败种植体的早期骨结合模式,以及表面污染在骨结合失败中可能起到的作用:采用组织学、电子显微镜和 X 射线光谱相结合的方法对未骨结合钛种植体的表面和周围生物组织进行了表征。形态学扫描电子显微镜显示表面不均匀,骨结合不规则。种植体表面主要被富含碳和氧的有机物覆盖。对三个种植体进行的能量色散 X 射线光谱表面分析表明,种植体上部和根尖区域都含有一些污染物。在一个或多个失败种植体的表面检测到碳、氮、钠、硅、氯、硫、金和锆。在周围组织中检测到纤维化、淋巴细胞和巨噬细胞浸润以及骨移植颗粒周围破骨细胞的高度活化:早期种植体失败的病因和机制,尤其是与鼻窦相关的病例,以及如何采取适当的管理干预措施将早期种植体失败率降至最低,是我们非常关注的问题。无论外科医生的操作多么自信和准确,整个过程中都可能存在无人知晓的未知错误。与其说是与种植体表面有关的错误,不如说是在对患者自身特有的鼻窦粘膜炎症或操作者自身的手术过程进行评估时出现的隐形问题。此外,有必要进行精心设计的研究,以揭示材料相关因素对急性鼻窦并发症和早期种植失败的影响。

Background: Various techniques with different grafts and implants have been proposed to establish a smooth and symmetric nasal dorsum with adequate function. Broadly, two categories of materials have been used in this regard: alloplastic implant materials and autograft materials. The aim of these meta-analyses is to explore the incidence of complications after dorsum augmentation surgery using alloplastic materials.

Materials and methods: After duplication removal 491 papers remained that title and abstract were assessed for eligibility. Regarding the study type, 27 observational studies were included, 21 retrospective and 6 prospective case series. A total of 3803 cases were enrolled in this systematic review and meta-analysis.

Result: Twenty-seven articles reported on complications and outcomes of dorsal augmentation rhinoplasty with synthetic materials. In a random-effects model, the weighted mean percentage was 2.75% (95% CI 1.61 to 4.17%). the weighted mean percentage were 1.91% (95% CI 0.77 to 3.54%), 0.72% (95% CI 0.316 to 1.31%), and 0.78% (95% CI 0.43 to 1.24%) respectively.

Conclusion: The widely used alloplasts were expanded polytetrafluoroethylene (ePTFE), high-density polyethylene, and silicone. The total rates for complications, infection, deviation, irregularity, hematoma, extrusion, and overcorrection were 2.75%, 1.91%, 0.72%, 0.70%, 0.78%, and 0.49%, respectively. The revision rate, based on the random effects model, was 6.40% with 95%CI (3.84 to 9.57).

Trial registration: This meta-analysis was registered at the International Prospective Register of Systematic Reviews (PROSPERO, registration number CRD42020209644 ).
