MethodsOne hundred and eighty-five patients with PTMC verified by surgery and pathology and underwent prophylactic CLN dissection were retrospectively reviewed. In accordance with lymph node metastasis, patients had been divided into metastasis team and non metastasis group. The dimensions, form, echo, aspect proportion, edge, protruding capsule, nodule location, calcification and calcification had been reviewed. The connection between clnm and ultrasonographic features, sex, age, single/multiple, whether or not with Hashimoto thyroiditis ended up being examined. ResultsAmong 185 clients with PTMC, 55 instances had lymph node metastasis, additionally the metastasis price had been 30.0%. In univariate evaluation, clnm of PTMC had been notably correlated with sex, age, tumefaction dimensions, protruding pill, form of calcification and single / several （all P less then 0.05）. In multivariate logistic regression evaluation, tumor size, single/multiple, protruding capsule, gender and age had been the chance elements of clnm. In line with the ROC bend, as soon as the age was 49.5 years of age in addition to mass dimensions ended up being 4.8 mm, the diagnostic test yoden index reached the most value. ConclusionWhen the danger elements of male, ≤49.5 years of age, cyst size≥4.8 mm, multiple and protruding pill appeared in PTMC clients, preventive CLN clearance should always be taken earnestly.ObjectiveTo improve the analysis and remedy for laryngeal schwannoma. Methods The medical data of 15 patients with laryngeal schwannoma had been retrospectively reviewed, including 5 male patients and 10 female patients. The tumors had been positioned in aryepiglottic fold in 4 cases, arytenoid region in 4 cases, interarytenoid in 2 cases, untrue singing cord in 2 situations low- and medium-energy ion scattering , epiglottis in 1 instance, singing cord in 1 instance, and subglottic region in 1 case. All clients underwent laryngeal mass resection under basic anesthesia, including 4 cases of tumor resection by additional approach and 11 situations of cyst DMOG resection by dental strategy. ResultsFollowing up for 13-80 months, 1 patient had reasonable sound after procedure. The hoarseness of 5 patients enhanced after procedure, not entirely restored. One client passed away of esophageal cancer at 49 months of follow-up, with no recurrence had been found through the follow-up period. The residual 8 cases had no obvious abnormalities. ConclusionThe clinical symptoms of laryngeal schwannoma vary, and the prognosis is generally good. The choice of surgical course is closely regarding the area and size of the laryngeal schwannoma. In the event that laryngeal schwannoma is really exposed under endoscopy, the tumefaction is removed by transoral radiofrequency coblation. Schwannomas on both sides of this subglottic area is resected by two surgeries, therefore the tracheotomy can be executed initially if necessary.ObjectiveTo investigate the partnership amongst the pneumatization amount of paranasal sinuses and skull base plus the occurrence of natural cerebrospinal substance rhinorrhea （SCSFR）. MethodsDate of 107 customers with SCSFR were evaluated retrospectively. Making use of CT scans, detective assessed the pneumatization amount of paranasal sinuses and head base, and contrasted classifications of various imaging qualities between SCSFR group（case group） and nasal septum deviation group（control group）, including front cells, Onodi cell, lateral recess of sphenoid sinus （LRSS）, pneumatization of anterior clinoid process and pneumatization of posterior clinoid procedure. ResultsOne hundred and eight fistulas are located among 107 situations. The most frequent web site for the fistulas is found in ethmoid sinus （38.89%）, followed closely by olfactory cleft（37.04%）, sphenoid sinus （21.30%） and frontal sinus （2.77%）.The occurrence of Onodi cellular had been significantly various between situation and control group（χ²=4.755, P0.05）. ConclusionThe most common site of SCSFR is ethmoid sinus, followed closely by olfactory cleft,the hyperpneumatization of the LRSS and Onodi mobile tend to be composite hepatic events closely related to its pathogenesis.ObjectiveTo measure the risk elements for metastasis regarding the lymph nodes posterior to your correct recurrent laryngeal nerve in thyroid gland micropapillary carcinoma（PTMC） by Meta-analysis. MethodsWe searched domestic and foreign databases for relevant scientific studies published up to June, 2020. Two separate reⅥewers performed literature screening and information extraction according to the addition and exclusion criteria. Then, Meta-analysis was performed using Revman 5.3 pc software. ResultsA total of 5 articles were included, with a total of 1884 subjects.The results of the study revealed that the rate of lymph node metastasis in PTMC Ⅵb area ended up being 10.8% （203/1884）. The chance elements for metastasis included customers’ age less then 45 years old, male, correct lobe tumor Diameter ≥0.5 cm, invading the envelope, Ⅵa lymph node metastasis. ConclusionⅥb lymph node dissection is recommended when there exists age less then 45 years, male intercourse, right lobe tumor≥0.5 cm, capsular invasion or Ⅵa lymph node metastasis.ObjectiveTo explore the clinical features of cephalic and facial restricted langerhans cell histiocytosis （LCH） in kids for increasing its diagnosis and treatment. MethodsClinical data of 8 young ones with cephalic and facial minimal LCH had been retrospectively examined, such as the onset time of infection, lesion location, imaging information, clinical manifestations and therapy methods. ResultsOne situation was preliminarily identified as chronic irritation with nasal straight back lesions, then conformed by repeated medical pathology. Six cases had been discovered to own simple cephalic and facial lumps without discomfort and swelling.
