    常见的外科技术旨在将带有中空皮瓣的整个vomerine粘膜转向口腔侧或鼻侧。由于与鼻粘膜的颜色相似,后一种方法被广泛执行。然而,我们缺乏对唇腭裂畸形的弯曲vomerine粘膜的组织学描述。
    我们使用苏木精-伊红对8例患者进行了组织学检查,高碘酸-希夫,ElastinvanGieson,和阿尔西亚的蓝色污渍。在手术期间在8月龄时获得组织样品。
    我们对覆盖在弯曲的子宫上的粘膜骨膜的组织学分析揭示了与口腔粘膜或鼻粘膜鳞状化生一致的特征,表现为包含许多浆膜腺体的复层鳞状上皮。一些区域显示出与呼吸道上皮化生相容的基底细胞的栅栏排列,但没有发现杯状细胞或呼吸道纤毛。存在丰富的纤维化和丰富的血管。
    黏膜无鼻粘膜特异性征象。这些发现应在术前left裂骨科和pa手术中加以考虑,以进一步完善。根据固定的生理信念改变子宫黏膜不应超过裂隙修复的其他重要方面,例如初级愈合以及建立腭顶和鼻底的最佳形式和功能。
    UNASSIGNED: Common surgical techniques aim to turn the entire vomerine mucosa with vomer flaps either to the oral side or to the nasal side. The latter approach is widely performed due to the similarity in color to the nasal mucosa. However, we lack a histologic description of the curved vomerine mucosa in cleft lip and palate malformations.
    UNASSIGNED: We histologically examined an excess of curved vomerine mucosa in 8 patients using hematoxylin-eosin, periodic acid-Schiff, Elastin van Gieson, and Alcian blue stains. Tissue samples were obtained during surgery at 8 months of age.
    UNASSIGNED: Our histological analysis of the mucoperiosteum overlying the curved vomer revealed characteristics consistent with those of an oral mucosa or a squamous metaplasia of the nasal mucosa, as exhibited by a stratified squamous epithelium containing numerous seromucous glands. Some areas showed a palisaded arrangement of the basal cells compatible with metaplasia of respiratory epithelium, but no goblet cells or respiratory cilia were identified. Abundant fibrosis and rich vascularity were present.
    UNASSIGNED: The vomer mucosa showed no specific signs of nasal mucosa. These findings should be considered in presurgical cleft orthopedics and palatal surgery for further refinement. Shifting the vomer mucosa according to a fixed physiologic belief should not overrule other important aspects of cleft repair such as primary healing and establishing optimal form and function of palatal roof and nasal floor.

    UNASSIGNED: To determine the prevalence and odds ratios for cleft lip and/or palate (CL/P) among infants prenatally exposed to opioids with or without neonatal opioid withdrawal syndrome (NOWS).
    UNASSIGNED: This study represents an exploratory, retrospective cohort study design of newborn medical health records from 2011 to 2016.
    UNASSIGNED: Records were drawn from a regional health system located in South Central Appalachia.
    UNASSIGNED: The original population yielded 3 cohorts of infants: (1) infants with opioid exposure (OE) but not requiring pharmacological intervention (OE; N = 168); (2) infants with NOWS requiring pharmacological intervention (N = 294); and (3) infants with no opioid exposure (NOE; N = 16 090), the primary comparison group.
    UNASSIGNED: Infants in the NOWS and OE groups showed significantly increased prevalence and odds ratios for CL/P when compared to those in the NOE group.
    UNASSIGNED: Prevalence rates per 1000 live births for infants with OE (35.71) and infants with NOWS (6.80) were significantly higher than those for infants with NOE (1.37). Comparison of infants with OE to the NOE group revealed significantly increased odds for CL/P, isolated cleft palate (CP), cleft lip (CL), and cleft lip and palate (CLP) (27.05, 41.81, 19.26, 19.37, respectively; all Ps < .008). The odds ratios for infants with NOWS compared to the NOE group were significantly higher for CL/P and CP (5.00 and 10.98, respectively; Ps < .03) but not for CL and CLP.
    UNASSIGNED: The results provide additional evidence that prenatal OE should be considered among the critical environmental risk factors that can contribute to CL/P.

    Cleft patients may develop an abnormal opening (fistula) between the oral and the nasal cavities. Surgical repair minimizes the adverse effect on speech and feeding. However, an obturator prosthesis is a nonsurgical approach to help close the communication. The purpose of the case report presented is to show the clinical use of an intraoral digital impression in the fabrication of obturator/speech aid appliances in children with cleft lip and palate deformity. Minimal adjustments were needed, and patients and caregivers responded positively. Prostheses demonstrated good stability and retention at delivery. The use of digital technology seems to have several benefits as an alternative method for capturing impressions, especially in young children with cleft lip and palate deformity.

    Bilateral Tessier type 4 craniofacial clefts are extremely rare and disfiguring malformations with vision-threatening ramifications. To date, there is no consensus in the literature with respect to the ideal surgical technique and management of these patients. Emergent eyelid reconstruction and additional procedures may be required to protect the cornea and avoid further ophthalmic and surgical complications. We present our experience and challenges of managing a case of bilateral Tessier type 4 clefting with an emphasis on oculoplastic considerations.

    确定了两个主要目标。第一个目标是使用口面裂痕(OFC)登记和民事登记来确定2012年至2015年泰国唇裂和/或腭裂(CL/P)的患病率。第二个目标是对该OFC注册表进行质量控制,尤其是出生缺陷注册(BDR)。
    基于注册表的调查。
    分析泰国国家卫生安全局的数据。
    2012年至2015年在泰国注册的CL/P患者。
    无。
    使用国民身份证号码(泰国身份证号码)和出生日期验证了重复记录。然后计算CL/P和特定表型的患病率。从这种患病率估计方法来看,OFC注册的质量保证是可能的。
    对于主要结果,CL/P的人群加权池患病率为2.14/1,000活产(95%置信区间为2.08~2.20).泰国身份证号码和费用报销系统是推动这一案件捕获的主要因素。然而,这种OFC注册仍然需要积极的病例发现和临床验证,改善员工培训和数据库联网。
    这项研究报道了泰国非常高的CL/P患病率。描述了这些OFCs注册表和BDR的优势和局限性。
    Two main objectives were established. First objective was to determine the prevalence of the cleft lip and/or cleft palate (CL/P) in Thailand from 2012 to 2015 using the orofacial clefts (OFCs) registry and civil registration. Second objective was to conduct a quality control of this OFC registry especially for the Birth Defects Registration (BDR).
    Registry-based survey.
    Analyzing data from the Thailand National Health Security Office.
    Registered patients with CL/P in Thailand from 2012 to 2015.
    None.
    Duplicated records were verified using National Identity Number (Thai ID#) and date of birth. The prevalence of CL/P and specific phenotypes was then calculated. From this prevalence estimate method, quality assurance of the OFCs registry was possible.
    For the main outcome, the population-weighted pool prevalence of CL/P was 2.14 per 1000 live births (95% confidence interval of 2.08-2.20). Thai ID# and expense reimbursement systems were the main factors driving this cases capturing. However, this OFCs registration still requires active case finding with clinical verification, improvement of staff training and databases networking.
    This study reported a very high CL/P prevalence of Thailand. Strengths and limitations of these OFCs registry and BDR were described.

    这是一项前瞻性研究,检查单侧唇腭裂(UCLP)患者在出生后第一个月的腭管型,在唇缘成形术之前,就在腭成形术前。没有患者接受术前骨科(鼻肺泡成型)。
    在这项前瞻性研究中,上弓石膏模型在治疗期间采取3次:在生命的第一个月(T1),唇膏整修前(T2),在腭成形术前(T3)。定义了解剖标志,然后获得了线性人体测量。使用3D软件进行尺寸分析。进行双向方差分析,然后进行Tukey检验进行统计分析。
    第三纪,机构。
    12例UCLP患者,无论性别,生命少于1个月,无任何其他综合征。
    未进行干预。
    在不使用骨科器械的情况下减少裂隙。
    与T1和T3相比,裂隙有统计学上显著的减少。与T2和T3以及T1和T3相比,犬间宽度也显着降低。与T2和T3以及T1和T3相比,后弓宽度显着增加。在分析的所有时间中,the板的宽度都增加了。
    在患者治疗的前6个月中,腭裂在中点和后点自发变窄。该事件通过唇缘成形术得到加强。与后弓区域相比,该手术对前弓宽度的影响可能更大。
    This is a prospective study examining palatal casts from patients with unilateral cleft lip and palate (UCLP) in the first month of life, immediately before cheiloplasty, and immediately before palatoplasty. None of the patients receives presurgical orthopedics (nasoalveolar molding).
    In this prospective study, upper arch plaster models were taken 3 times during the treatment: in the first month of life (T1), before the cheiloplasty (T2), and before the palatoplasty (T3). Anatomic landmarks were defined and linear anthropometric measurements were obtained afterward. Dimensional analysis was performed using 3D software. Two-way analysis of variance followed by Tukey test was performed for statistical analysis.
    Tertiary, institutional.
    Twelve patients with UCLP of either sex with less than 1 month of life and without any other syndrome.
    No intervention was performed.
    Reduction of the cleft without using orthopedics apparatus.
    There was a statistically significant reduction in the cleft gap comparing T1 to T3. There was also a significant reduction in the intercanine width comparing T2 and T3, and T1 and T3. There was significant increase in the posterior arch width comparing T2 and T3, and T1 and T3. The palatal plate\'s width increased in all times analyzed.
    The palatal cleft narrows spontaneously as well in both midpoint and posterior point during the first 6 months of patient\'s treatment. This event was enhanced by cheiloplasty. This surgery might have a greater influence on the anterior arch width than in the posterior arch region.

    Pituitary hormone deficiencies may occur in children with midline defects; in these cases, hypogonadism is usually hypogonadotropic. Herein, we report a boy at the age of 13.8 years with mild mental retardation, previously operated for complete cleft palate (isolated) and presented with hypoglycemia due to isolated secondary adrenal insufficiency, who further had a decrease in testicular size with increased follicle-stimulating hormone level (hypergonadotropic hypogonadism) and diagnosed with Klinefelter syndrome. Klinefelter syndrome in childhood is rarely diagnosed and cases are observed in a wide spectrum. Although some regional duplications of the X chromosome also show midline defects such as spina bifida-neural tube defects, mental retardation, hypopituitarism (mostly growth hormone deficiency); coexistence of Klinefelter syndrome and isolated secondary adrenal deficiency/midline defect in our case may also be coincidental. However, to our knowledge, this is the first case in literature with this association in a patient with a 47, XXY karyotype.

  • 文章类型: Case Reports
    Ankyloglossia superior syndrome is an extremely rare entity in which centrally located glossopalatine ankylosis is a principal feature. Some cases are accompanied by cleft palate, micrognathia, or tongue hypoplasia, and affected patients need careful nutritional and respiratory support. We describe a newborn girl in whom ankyloglossia superior syndrome comprised complex craniofacial malformations, including cleft palate, micrognathia, microglossia, and natal teeth as well as limb anomalies. Surgical treatment entailed release of synechiae, and glossopexy was performed successfully to prevent postsurgical airway complications and to ensure adequate nutrition by nipple feeding during infancy.

    This case report presents a palatal cleft that healed spontaneously, with complete formation of mucosa and bone. Even though the nasal structures could initially be observed through the cleft palate, a thin membrane sealed any communication between the oral and nasal cavities. The origin of this tenuous membrane cannot be fully understood with current discernment of palate formation, but it probably served as a basis for the formation of the other tissues. No previous record of nonintervened spontaneous closure of a cleft palate has been reported.

    To evaluate patency of circummaxillary sutures in children with Apert, Crouzon, and Pfeiffer Syndromes and to compare it to a nonsyndromic matched control group.
    Case-control study.
    Tertiary care public hospital.
    Thirty-eight computed tomography (CT) scans of patients affected by syndromic craniofacial synostosis (13 patients with Apert syndrome, 20 patients with Crouzon syndrome, and 5 patients with Pfeiffer syndrome), average age 5 ± 2.8 years, range 1.9 to 12 years, were compared to age- and sex-matched control CTs of 38 nonsyndromic children. Computed tomography scans of the study group had to be performed prior to any midfacial surgery.
    Midpalatal suture, zygomaticomaxillary sutures, and pterigomaxillary sutures were evaluated and scored.
    The syndromic group showed a significant earlier ossification of all sutures compared to the nonsyndromic group. Significant differences were already present in early childhood and continued through adolescence.
    Based on the differences in terms of maxillary sutural ossification identified, midfacial hypoplasia does not seem to be only secondary to premature cranial base ossification, but also to primary synostosis of facial sutures, thus providing new insights into the pathogenesis of midface deficiency in children with craniofacial-synostosis. Care should be taken when planning any maxillary orthopedics, such as expansion or maxillary protraction, given the high frequency of early fusion of circummaxillary sutures.
