Comparison of postoperative paresthesia after sagittal split osteotomy among different fixation methods: a one year follow-up study

OBJECTIVES: Postoperative paresthesia is a common complication after sagittal split osteotomy (SSO). This study aimed to compare paresthesia among different fixation methods one year postoperative. MATERIALS AND METHODS: This prospective cohort study assessed subjects in four groups: class II with miniplate fixation (Group 1), class II with three-screw fixation (Group 2), class III with miniplate fixation (Group 3), and class III with three-screw fixation (Group 4). Paresthesia was evaluated one year postoperative based on a 0-10 visual analogue scale. Pearson correlation was used to evaluate associations of age and mandibular movement with paresthesia. ANOVA was used to compare paresthesia among groups. RESULTS: A total of 80 subjects were enrolled, with 20 subjects in each of the four groups. The Pearson correlation test demonstrated a significant correlation between mandibular movement and paresthesia (P=0.001). Comparison of paresthesia among the groups showed significant differences among groups 1 and 2, 2 and 3, and 3 and 4 (P<0.05). CONCLUSION: The three-screw fixation method led to more paresthesia one year postoperative compared with miniplate fixation. In addition, the magnitude of mandibular movement had a positive correlation with paresthesia.

Ultrasound Diagnosis of Fetal Thanatophoric Skeletal Dysplasia:Three Cases Report and a Brief Review / 华中科技大学学报（医学）（英德文版）

Congenital skeletal deformity of ferns varies and may be attributed to a range of reasons.Congenital skeletal deformity seriously affects body function or even leads to neonatal death directly.The disease brings great pain to victim and their family.We reviewed the fetal prenatal ultrasonic data conducted during period from Jan.2013 to June 2016,and there were 84 fetuses with skeletal abnormalities among 12 000 cases,and 3 fetuses with thanatophoric dysplasia.Our report described and reviewed three common types of thanatophoric dysplasia,aiming to explore the value of standardized prenatal ultrasonic diagnosis of fetal abnormalities in the skeletal system.

Expansión quirúrgica asistida de maxila para rehabilitación implanto asistida / Assisted maxillary expansion for oral rehabilitation with dental implants

El objetivo de este articulo es presentar el caso de un paciente con diagnóstico de deficiencia transversal de maxila tratado para rehabilitar el sector anterior. El diagnóstico de la deformidad dento facial se realizó utilizando estudios de rutina que incluyen análisis de imagen y clínicos determinando una compresión maxilar con mordida cruzada posterior bilateral y mal posición de dientes 11 y 21; el diente11 presentaba alteraciones óseas y dentarias imposibles de rehabilitar llevando a la exodoncia del diente. Se desarrollo posteriormente la técnica de expansión asistida quirúrgicamente de maxila para mejorar los espacios de instalación y la oclusión del paciente. Posteriormente se realizó la instalación del implante y su rehabilitación con prótesis fija singular. Se discute el tratamiento interdisciplinario y las opciones utilizadas en el abordaje. Se concluye que la integración de diagnósticos dentales, esqueletales y faciales permite establecer terapias adecuadas en casos complejos.

The aim of this paper is to show a case of a patient with a transversal deficience of maxillae treated to make rehabilitation in the anterior area. The diagnosis of dentofacial deformities was realized using routine studies incorporating image and clinical analysis to observe the bilateral posterior crossbite and abnormal position in tooth 11 and 21; the 11 showed alterations in bone and teeth with no possibilities to make the prosthetic treatment making the dental extraction. Later, was realized the installation of the implant and the rehabilitation with fixed prosthesis. Is discussed the treatment and the options used in the approach. Was concluded that the integration of diagnosis dental, skeletal and facial could make an adequate therapy in complex cases.

Satoyoshi Syndrome.

Satoyoshi syndrome is a rare autoimmune disease characterized by alopecia, painful muscle spasms, diarrhea and secondary skeletal changes. We report a 11- year old girl presenting with the typical features of alopecia totalis, severe muscle spasm and skeletal deformities.

Clinical and Radiographic Features of Short Stature Combined with Skeletal Deformity in Children / 实用儿科临床杂志

Objective To analyze the clinical and radiographic features of short stature combined with skeletal deformity in children,and to diagnose exactly and cure promptly in children.Methods One hundred and twenty children were collected,included 69 males and 51 females.All of the children were collected detail medical history including history of birth,feeding,growth and development and family history and taken both physical and X ray examination that bone age could be evaluate by Gruelich-Pyle method.The children were taken a laboratory examination including calcium,phosphours,alkaline phosphatase,chromosome karyotype,and so on.Results Among 120 children,there were 36 cases(30.0%) of achondroplasia,20 cases(17.0%)of Turner syndrome,10 cases(8.0%)of multiple epiphyseal dysplasia,1 case(0.8%)of spondyloepiphseal dysplasia congenital,7 cases(5.8%) of spondyloepiphyseal dysplasia tarda,2 cases(1.6%) of osteogenesis imperfecta,1 case(0.8%) of cleidocranial dysplasia,5 cases(4.2%)of mucopolysaccharide Ⅳ,5 cases(4.2%) of pseudoachondroplasia,9 cases(7.5%)of hypophosphatemic ricket,24 cases(20%)of short limb dwarf.Among 120 cases,27 were regularity dwarfism(22.5%),93 cases were irregularity dwarfism(77.5%);Among 93 cases of irregularity dwarfism,80 cases were short limb dwarfism including 36 cases of short upper limb(short upper arm 35 cases,shortforearm 1 case),20 cases of short lower limb,24 cases of proportional short stature,13 cases of short trunk.X ray bone age lag 46 cases,ahead of schedule 15 cases(12.5%),normal 59 cases.Conclusions The main causes of short stature combined with skeletal deformity are genetic bone disease.To analyze the feature of clinical and radiographic is a valuble instrument for the children diagnosis of short stature combined with skeletal deformity.Part of them skeletal age were lagged.
