Objective To study the effect of scan position consistency on computer tomography-magnetic resonance (CT-MR) images automatic registration in patients with nasopharyngeal carcinoma.Methods Fifteen patients with nasopharyngeal carcinoma were enrolled in this study and scanned with the same position to acquire CT images and MR-1 images. Then they were reacanned with different position for MR-2 images. Image registration of CT-MR-1 and CT-MR-2 was finished using mutual information method.The registration errors were evaluated by measuring the distances between marks. Results The error of au-tomatic CT-MR registration with consistent scan position was 1.32 nun, comparing with the minimum of 2.00 ram and the maximum of 3.83 mm with different positions. Conclusion Keeping consistent scan position can improve the accuracy of image registration.

Objective:To construct an inpatient-outpatient-home step swallowing rehabilitation training program for partial laryngectomy patients.Methods:From June 2022 to May 2023, a preliminary program for inpatient-outpatient-home step swallowing rehabilitation training for partial laryngectomy patients was developed through literature search and analysis. Delphi method was used for two rounds of expert inquiry on the inpatient-outpatient-home step swallowing rehabilitation training program for partial laryngectomy patients.Results:A total of 15 experts were included for two rounds of expert inquiry. The effective response rates of the questionnaires from the two rounds of expert inquiries were 100.0% (15/15). The expert authority coefficients for the two rounds of inquiry were 0.885 and 0.855, respectively, and the Kendall harmony coefficients were 0.217 and 0.230, respectively ( P<0.01). The final inpatient-outpatient-home step swallowing rehabilitation training program for partial laryngectomy patients included three primary items (swallowing training step, swallowing training methods, and feeding guidance methods), 21 secondary items, and 35 tertiary items. Conclusions:The inpatient-outpatient-home step swallowing rehabilitation training program for partial laryngectomy patients based on the Delphi method has certain scientific and feasibility and can provide a reference for medical and nursing staff.

Objective To evaluate the effect of different operation methods on the early swallowing function in the patients with laryngocarcinoma.Methods A total of 138 patients with the first time of open laryngectomy in this hospital from January 2021 to December 2022 were selected as the research subjects by convenience sampling method.The patients were divided into the vertical laryngeal resection group(vertical group,n=34),horizontal laryngeal partial resection(horizontal group,26 cases),suprachloroid laryngeal par-tial resection annular hyoid epiglottis fixation group(SCPL-CHEP group,n=26)and total laryngeal resection group(total laryngeal group,n=52)according to the operation methods.The Anderson Dysphagia Scale,Syd-ney Dysphagia Scale and modified swale drinking water test were used to evaluate the swallowing function on the first day of postoperative oral feeding in the patients.Results The total scores and scores of various di-mensions of the Chinese version of Anderson Dysphagia Scale,total scores and scores of various dimensions of Sydney Swallowing Scale and the results of the modified swale drinking water test had statistical differences a-mong the various groups(P＜0.01);the above indexes had statistical difference between the total laryngeal group and the other groups(P＜0.01),but the above indexes had no statistical difference between the two groups in the horizontal group,vertical group and SCPL-CHEP group(P＞0.05).Conclusion In the patients with laryngeal cancer undergoing open laryngectomy,the dysphagia is less severe during early eating after to-tal laryngectomy,which has little impact on life.

Objective To explore the effects of evidence-based nursing practice on reducing the incidence of pharyngo-cutancous fistula, shortening hospital day after surgery and easing the financial burden among laryngectomy patients.Methods From June 2017 to March 2018, we selected laryngectomy patients as subjects in Beijing Tongren Hospital. Patients were numbered according to the order being admitted to hospital and randomly divided into two groups with the random number table. Control group (n=51) received routine nursing. Experimental group (n=50) carried out routine nursing along with transforming evidence into nursing plan, implementing and evaluating nursing care effects by the Johns Hopkins nursing evidence-based practice (JHNEBP) model. We observed the incidence of pharyngo-cutancous fistula and hospital stay of patients between two groups.Results The incidence of pharyngeal fistula of experimental group and control group were 10.00 ％ and 27.45％ respectively with a significant difference (χ2=5.034,P=0.025). The hospital day of experimental group and control group were (12.78±3.99)d and (17.22±6.45)d respectively with a significant difference (t= -4.151,P<0.001).Conclusions The evidence-based nursing practice based on JHNEBP can reduce the incidence of pharyngo-cutancous fistula and shorten hospital day after surgery.

Objective? To explore the mental state of laryngeal carcinoma patients after total laryngectomy and to analyze its correlations with coping style and social support. Methods? From January 2017 to October 2017, we selected 36 laryngeal carcinoma patients with total laryngectomy in otolaryngology dead and neck surgery at Beijing Tongren Hospital, Capital Medical University as subjects by convenience sampling. All of the patients were investigated with the Self-rating Depression Scale (SDS), Self-rating Anxiety Scale (SAS), Medical Coping Modes Questionnaire (MCMQ) and Social Support Rating Scale (SSRS). A total of 36 questionnaires were sent out and 34 of them were collected. Results? Among 34 patients, the total scores of SAS and SDS were (45.38±10.27) and (50.32±11.82) respectively. The score of "avoidance" coping style of patients after total laryngectomy was higher than that of norm with a statistical difference (P＜ 0.05). Pearson correlation analysis showed that SAS and SDS were negatively correlated with the total score of social support (P＜0.05);SAS and SDS were positively correlated with the confrontation dimension of coping style (P＜0.05), and were negatively correlated with the avoidance dimension (P＜ 0.05). Conclusions? After total laryngectomy, patients are with high levela of anxiety and depression. Medical staff should guide patients to take correct coping styles after surgery to face diseases, and improve patients' social support to relieve patients' negative emotions and total laryngectomy,and to promote the rehabilitation of diseases.

Objective:To explore the effects of swallowing rehabilitation training on swallowing function and quality of life in patients after laryngectomy.Methods:Randomized controlled trials on the effects of swallowing rehabilitation training on swallowing function and quality of life in postoperative laryngeal cancer patients were electronically retrieved from the Cochrane Library, PubMed, Embase, Web of Science, CINAHL, China National Knowledge Infrastructure, WanFang Data, VIP, and China Biology Medicine disc. The search period was from database establishment to February 1, 2024. The quality evaluation criteria for randomized controlled trials of Joanna Briggs Institute Evidence-Based Health Care Center (2016) was used to evaluate the included literature. RevMan 5.3 software was used for meta-analysis.Results:A total of ten articles were included, with 987 patients. Meta-analysis showed that swallowing rehabilitation training could improve the swallowing function ( P<0.01) and quality of life ( P<0.01) of patients after laryngectomy. Conclusions:Swallowing rehabilitation training can improve patients' swallowing function and quality of life after laryngectomy and is worth applying in clinical practice.
