Objective To investigate the feasibility and results of the application of both expanded cutaneous flap and temporoparietal fascia flap in total ear reconstruction with Medpor framework.Methods The main procedures consisted of three stages:stage Ⅰ-skin expansion,stage Ⅱ auricle formation that consisted of orientation of Medpor implant and creation of coverage for the implant by both expaned skin flap and temporoparietal fascia flap,and stage Ⅲ-treatment of residual ear and recontruction of auricular lobule. Results Twenty-two ears in 22 unilateral microtia patients were constructed using Medpor implants covered with both expanded cutaneous flap and temporoparietal fascia flap over the last three years,and they were accepted as pleasing by the patients.Conclusions Application of both expanded cutaneous flap and temporoparietal fascia flap can assure no extrusion of Medpor implant in ear reconstruction.Further more,the two layers of transferred tissues will not affect the profile details of the reconstructed ear.And because the skin covering the framework and fascia is derived from frommastoid region,the appearance and profile of the reconstructed auricle is true to nature and close to that of the opposite one.

Objective:To explore the clinical effect of different surgical methods combined with Neoadjuvant chemotherapy in treating patients with breast cancer.Methods:80 patients treated and diagnosed in our hospital from January,2012 to January,2014 were enrolled in the present study.According to the willingness,physical condition and financial situation,they were divided them into group A (23 cases) and group B (57 cases).Neoadjuvant chemotherapy of EC regimens (epirubicin+cyclophosphamide) was applied to both groups,on the basis of which,group A received breast-conserving surgery,group B received modified radical mastectomy.The clinical effect,breast cosmetic result,life quality,psychological states were compared in both groups.Results:The operation time,extubation time were significantly shorter than those of group B (p ＜0.05),the amount of bleeding,AMA,HRSD score,occurrence rate of complications in group A were significantly lower than those of group B (p＜0.05),the breast cosmetic result of group A was obviously better than that of group B (p＜0.05),and the QLQ-BR23 score in group A was significantly higher than that of group B (p＜0.05).The 2-year survival rate and 2 year recurrence rate showed no statistical difference between the two groups (p ＞0.05).Conclusion:Breast-conserving surgery combined with epirubicin neoadjuvant chemotherapy was effective in treating breast cancer,which could decrease the complications,improve the breast cosmetic result and quality of life.

Objective To explore the role of ultrasound-guided core needle biopsy in diagnosis and treatment of thyroid nodules.Methods 778 cases undergoing ultrasound-guided core needle biopsy in our department from Jan.2012 to Dec.2014 were retrospectively analyzed,and the sensitivity,specificity and accuracy were calculated.Results All the patients were operated successfully.Except for 21 nodules undiagnosed,16.4％ (124/757) were histologically diagnosed as malignant and 83.6％ (633/757) were benign.15 samples of the 124 malignant nodules were less than 10 millimeter in diameter.The sensitivity,specificity and accuracy were 100％,94.8％ and 95.6％,respectively.Of the ultrasound features,blood flow,boundary,internal situation and calcification were statistically significant between benign and malignant nodules,but not so between the groups of different greatest dimentions.Conclusion Ultrasound-guided core needle biopsy is safe and effective for obtaining thyroid nodule tissue,and it is helpful for diagnosis of thyroid diseases.

With the increasing proportion of human papilloma virus(HPV)infection in the pathogenic factors of oro-pharyngeal cancer,a series of changes have occurred in the surgical treatment.While the treatment mode has been im-proved,there are still many problems,including the inconsistency between diagnosis and treatment modes,the lack of popularization of reconstruction technology,the imperfect post-treatment rehabilitation system,and the lack of effective preventive measures.Especially in terms of treatment mode for early oropharyngeal cancer,there is no unified conclu-sion whether it is surgery alone or radiotherapy alone,and whether robotic minimally invasive surgery has better func-tional protection than radiotherapy.For advanced oropharyngeal cancer,there is greater controversy over the treatment mode.It is still unclear whether to adopt a non-surgical treatment mode of synchronous chemoradiotherapy or induction chemotherapy combined with synchronous chemoradiotherapy,or a treatment mode of surgery combined with postopera-tive chemoradiotherapy.In order to standardize the surgical treatment of oropharyngeal cancer in China and clarify the indications for surgical treatment of oropharyngeal cancer,this expert consensus,based on the characteristics and treat-ment status of oropharyngeal cancer in China and combined with the international latest theories and practices,forms consensus opinions in multiple aspects of preoperative evaluation,surgical indication determination,primary tumor re-section,neck lymph node dissection,postoperative defect repair,postoperative complication management prognosis and follow-up of oropharyngeal cancer patients.The key points include:① Before the treatment of oropharyngeal cancer,the expression of P16 protein should be detected to clarify HPV status;② Perform enhanced magnetic resonance imaging of the maxillofacial region before surgery to evaluate the invasion of oropharyngeal cancer and guide precise surgical resec-tion of oropharyngeal cancer.Evaluating mouth opening and airway status is crucial for surgical approach decisions and postoperative risk prediction;③ For oropharyngeal cancer patients who have to undergo major surgery and cannot eat for one to two months,it is recommended to undergo percutaneous endoscopic gastrostomy before surgery to effectively improve their nutritional intake during treatment;④ Early-stage oropharyngeal cancer patients may opt for either sur-gery alone or radiation therapy alone.For intermediate and advanced stages,HPV-related oropharyngeal cancer general-ly prioritizes radiation therapy,with concurrent chemotherapy considered based on tumor staging.Surgical treatment is recommended as the first choice for HPV unrelated oropharyngeal squamous cell carcinoma(including primary and re-current)and recurrent HPV related oropharyngeal squamous cell carcinoma after radiotherapy and chemotherapy;⑤ For primary exogenous T1-2 oropharyngeal cancer,direct surgery through the oral approach or da Vinci robotic sur-gery is preferred.For T3-4 patients with advanced oropharyngeal cancer,it is recommended to use temporary mandibu-lectomy approach and lateral pharyngotomy approach for surgery as appropriate;⑥ For cT1-2N0 oropharyngeal cancer patients with tumor invasion depth＞3 mm and cT3-4N0 HPV unrelated oropharyngeal cancer patients,selective neck dissection of levels ⅠB to Ⅳ is recommended.For cN+HPV unrelated oropharyngeal cancer patients,therapeutic neck dissection in regions Ⅰ-Ⅴ is advised;⑦ If PET-CT scan at 12 or more weeks after completion of radiation shows intense FDG uptake in any node,or imaging suggests continuous enlargement of lymph nodes,the patient should undergo neck dissection;⑧ For patients with suspected extracapsular invasion preoperatively,lymph node dissection should include removal of surrounding muscle and adipose connective tissue;⑨ The reconstruction of oropharyngeal cancer defects should follow the principle of reconstruction steps,with priority given to adjacent flaps,followed by distal pedicled flaps,and finally free flaps.The anterolateral thigh flap with abundant tissue can be used as the preferred flap for large-scale postoperative defects.
