OBJECTIVE: To investigate the neoplasia of fossa orbitalis, hard palate and the anterior skull base defect by making use of mucoperiosteal flap of nasal septum. METHOD: A retrospective study was reviewed in 12 patients with tumors in nasal cavity and nasal sinuses. According to tumor character and range, by partial or total maxillectomy and ethmoidectomy, fossa orbitalis, hard palate and the anterior skull base defects were repaired synchronously on the heels of resection of the tumors which damaged fossa orbitalis, hard palate and the anterior skull base. RESULT: Among the 12 patients there were 5 patients with the destructions on ethmoidal horizontal plate, 2 patients with the destructions on hanging wall of ethmoid, 1 patient with the destruction on hanging wall of fossa orbitalis, 1 patient with the destruction on medial wall of fossa orbitalis and on floor of orbit respectively, 2 patients with the destructions on hard palate and all the destructions were repaired following detection synchronously. There were no complications of surgical death, cerebrospinal fluid leaks, encephalomeningocele. CONCLUSION During the operation of tumor in nasal cavity and/or nasal sinuses when defect of fossa orbitalis, hard palate and anterior skull base were found and the defects need repair, we can take advantages of mucoperiosteal flap of nasal septum to perform the transplantation of mucoperiosteal flap in order to avoid forming local defect.

Objective:To explore the accuracy of intelligent calculation (IC) method for risk assessment of hospitalization for patients, aiming to build a more advantageous risk assessment system.Methods:The "Search Engine" program was developed based on hospital information system (HIS) of the Fifth Center Hospital in Tianjin, which automatically captured patient information and generated nutritional risk screening 2002 (NRS 2002) score, Caprini thrombosis risk assessment model and Padua thrombosis risk assessment model for venous thromboembolism (VTE), the CHA 2DS 2-VASc for predicting stroke risk stratification in atrial fibrillation and the HAS-BLED for predicting bleeding risk in anticoagulated patients with atrial fibrillation. A randomized controlled trial was conducted. According to the applicable conditions of each risk assessment, 100 risk scores from "Search Engine" program belonged to each risk assessment were randomly selected, defined as the IC group. Manual scoring with the data of the same case at the same time, defined as the traditional calculation (TC) group, compared the consistency of the scores and the difference in time-consuming between the two groups. Results:The Bland-Altman plots showed that the 95% limits of agreement (95% LoA) of NRS 2002 score, Caprini score, Padua score, CHA 2DS 2-VASc score and HAS-BLED score was -0.46 to 0.41, -0.49 to 0.52, -0.50 to 0.41, -0.67 to 0.60, -0.44 to 0.43, respectively, all P > 0.05. In this study, the Bland-Altman plot showed that 95%, 96%, 97%, 97%, 95% plots fell within the 95% LoA in NRS 2002 score, Caprini score, Padua score, wwCHA 2DS 2-VASc score and HAS-BLED score by the two methods, respectively. The all plots of 95% LoA were within the clinically acceptable range (-0.5 to 0.5 scores). The time-consuming of NRS 2002 score, Caprini score, Padua score, CHA 2DS 2-VASc score and HAS-BLED score in IC group were significantly shorter than those in TC group [0.72 (0.71, 0.73) seconds vs. 361.02 (322.41, 361.02) seconds, 0.72 (0.72, 0.73) seconds vs. 196.68 (179.99, 291.20) seconds, 0.72 (0.72, 0.73) seconds vs. 105.75 (92.32, 114.70) seconds, 0.72 (0.71, 0.72) seconds vs. 72.66 (56.24, 84.20) seconds, 0.72 (0.71, 0.72) seconds vs. 51.30 (38.88, 57.15) seconds, respectively, all P < 0.001]. Conclusion:For the above five risk assessments, the TC method and IC method has good consistency in scores, and the IC method is faster, which has good application prospect for clinical application.

Objective:To explore the characteristics of the changes in risk score for intensive care unit (ICU) patients during hospitalization by the intelligent calculation method, and to provide evidence for the risk prevention.Methods:In this retrospective study, ICU patients of the Fifth Central Hospital in Tianjin from November 3, 2021 to March 28, 2022 were enrolled and divided into ≥ 14 days group, 10-13 days group, 7-9 days group, and 3-6 days group according to the ICU length of stay. Risk scores assessed by the intelligent calculation method of the ICU patients were collected, including nutritional risk screening 2002 (NRS 2002), Caprini score and Padua score. NRS 2002 score for all patients, Caprini score for surgical patients and Padua score for internal medicine patients were selected. Trends in change of each score were compared between patients admitted to ICU 1, 3, 7 (if necessary), 10 (if necessary), and 14 days (if necessary).Results:A total of 138 patients were involved, including 79 males and 59 females, with an average age of (61.71±18.86) years and an average hospital stay of [6.00 (4.00, 9.25)] days. ① in the group with ICU length of stay ≥ 14 days (21 cases): there was no significant change in the NRS 2002 scores of the patients within 10 days, but the NRS 2002 score was significantly decreased in 14 days as compared with 1 day [3.00 (2.50, 3.50) vs. 4.00 (3.00, 5.00), P < 0.05]; both Caprini and Padua score were increased with prolonged hospital stay and compared with 1 day, the scores at the other time points were significantly increased, especially at 14 days [Caprini score: 5.00 (3.25, 7.00) vs. 2.50 (1.25, 5.50), Padua score: 6.00 (6.00, 7.00) vs. 3.00 (1.00, 3.00), both P < 0.05].② in the group with ICU length of stay from 10-13 days (15 cases): with the prolonged hospital stay, there was no significant change in NRS 2002 score, but both Caprini and Padua score were increased at 3, 7, 10 days, especially at 10 days [Caprini score: 3.00 (2.00, 4.75) vs. 2.00 (0.25, 2.75), Padua score: 5.00 (3.50, 6.00) vs. 2.00 (0.50, 4.00), both P < 0.05].③ in the group with ICU length of stay from 7-9 days (23 cases): compared with 1 day, the NRS 2002 score at 3 days and7 days were decreased, but the Caprini and Padua score were increased, especially at 7 days [NRS 2002 score: 2.00 (1.00, 4.00) vs. 2.00 (2.00, 4.00), Caprini score: 3.00 (2.00, 5.50) vs. 2.00 (0.25, 3.00), Padua score: 5.00 (4.00, 6.00) vs. 2.00 (0, 2.00), all P < 0.05]. ④ in the group with ICU length of stay from 3-6 days (79 cases): compared with 1 day, the NRS 2002 score at 3 days was decreased [NRS 2002 score: 2.00 (1.00, 3.00) vs. 2.00 (1.00, 3.00), P < 0.05], Caprini and Padua score were significantly increased [Caprini score: 3.00 (2.00, 4.00) vs. 2.00 (1.00, 3.00), Padua score: 5.00 (4.00, 5.00) vs. 2.00 (1.00, 3.00), both P < 0.05]. Conclusion:Based on dynamic assessment of intelligent calculation methods, the risk of thrombosis in ICU patients increased with hospital length of stay, and the nutritional risk was generally flat or reducing in different hospitalization periods.

Objective To summarize the experience of minimally invasive tracheotomy under veno-venous extracorporeal membrane oxygenation(VV-ECMO)in 4 cases of severe pneumonia,and to provide examples for airway management of severe pneumonia patients.Methods A retrospective study method was conducted.Four cases of severe pneumonia patients who underwent extracorporeal membrane oxygenation(ECMO)at the intensive care unit(ICU)of Shandong Provincial Hospital Affiliated to Shandong First Medical University from November 2022 to March 2023 were selected as the study subjects,clinical data on the general conditions,imaging examinations before and after admission to ICU,changes in biochemical indexes before and after ECMO technique,and the performance of bedside minimally invasive tracheotomy were collected.Bedside tracheotomy was performed to assist ventilation for patients according to the change of condition.The changes and prognosis of the patients were observed.Results Four patients with severe pneumonia were treated with bedside tracheotomy-assisted ventilation in the state of continuous VV-ECMO,the oxygen saturation was maintained between 0.98-1.00,the airway was cleared and sputum evacuation was smooth,the vital signs were stable after the operation,and the machine was gradually withdrawn.Conclusion During the treatment of severe pneumonia,the safe and rapid completion of bedside minimally invasive tracheotomy in patients with severe pneumonia under continuous VV-ECMO is a new challenge shared by doctors and nurses of otorhinolaryngology,head and neck surgery,and critical care emergency care unit.The four successful cases of bedside tracheotomy after VV-ECMO treatment we report suggest that bedside minimally invasive tracheotomy can safely and rapidly assist airway management,and may provide more useful experiences for the treatment of severe pneumonia and possible new acute respiratory infectious diseases in the future.

Objective:To analyze the significance and factors influencing of CT scan under the modified Valsalva maneuver. Methods:Clinical data of 52 patients with hypopharyngeal carcinoma diagnosed from August 2021 to December 2022 were collected, all patients had calm breathing CT scan and modified Valsalva maneuver CT scan. Compare the exposure effect of the aryepiglottic fold, interarytenoid fold, postcricoid area, piriform fossa apex, posterior hypopharyngeal wall, and glottis with each CT scanning method. The effects of age, neck circumference, neck length, BMI, tumor site, and T stage on the exposure effect were analyzed. Results:In 52 patients, 50 patients（96.15%） completed CT scan at once time. The exposure effect of the CT scan under modified Valsalva maneuver in the aryepiglottic fold, interarytenoid fold, postcricoid area, piriform fossa apex, posterior hypopharyngeal wall was significantly better than CT scan under calm breathing（Z=-4.002, -8.026, -8.349, -7.781, -8.608, all P<0.01）, while CT scan under modified Valsalva maneuver was significantly worse in glottis than CT scan under calm breathing（Z=-3.625, P<0.01）. In the modified Valsalva CT scan, age had no obvious effect on the exposure effect. The exposure effect was better with long neck length, smaller neck circumference, smaller BMI and smaller T stage. The exposure of postcricoid carcinoma was better than pyriform sinus carcinoma and posterior hypopharyngeal wall carcinoma. But differences were not all statistically significant. Conclusion:The anatomical structure of the hypopharynx was clearly under CT scan with modified Valsalva maneuver, which clinical application is simple, but the effect of glottis was worse. The influence of age, neck circumference, neck length, BMI, and tumor T stage on the exposure effect still needs further investigation.
