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.

BACKGROUND: The purpose of this retrospective study was to develop a two- and three-dimensional analysis of the airway using cone-beam computed tomography (CBCT) and to determine whether the airway space would be changed in mandibular prognathism after bimaxillary surgery involving maxillary posterior impaction. METHODS: Patients requiring orthognathic surgery from 2012 to 2014 were recruited for this study. CBCT scans were obtained at three points: preoperatively (T0), immediate postoperatively (T1), and after 6 months postoperatively (T2). The nasopharynx, oropharynx, and hypopharynx were measured on the CBCT scan for each patient in a repeatable manner. With the midsagittal plane, linear measurements in the middle of each were obtained. For the CBCT, volumetric measurements of each and total airway were obtained. RESULTS: A total of 22 consecutive patients (11 men and 11 women) were included in the present study. The total volume was significantly reduced (p < .001). However, the change of the diameter and volume of the nasopharynx was not statistically significant (p = .160, p = .137, respectively). In the oropharynx, the change of both the diameter and volume showed statistical significance between preoperatively and immediate postoperatively (p < .001, p = .001, respectively) and also preoperatively and after 6 months postoperatively (p = .001, p = .010, respectively). In the hypopharynx, the change of both the diameter and volume showed statistical significance between preoperatively and immediate postoperatively (p = .001, p < .001, respectively) and also preoperatively and after 6 months postoperatively (p = .001, p < .001, respectively). CONCLUSIONS: The bimaxillary surgery involving maxillary posterior impaction can reduce the volume of airway in the patients of mandibular prognathism. Although total airway volume was reduced significantly, the changes in the volume and diameter of the nasopharynx were not statistically significant. The maxillary posterior impaction affects on the nasopharyngeal airway minimally.

OBJECTIVE: To evaluate the clinical effect of acellular dermal matrix (ADM) on the repair of different tissue defects in pharyngeal and laryngeal cancer. METHOD: Twenty-three cases of pharyngeal and laryngeal cancer were analyzed retrospectively, including 16 patients with pharyngeal cancer, and 7 patients with laryngeal cancer. After surgery, the patients appeared two types of tissue defects respectively: hypopharynx tissue defect and neck skin tissue defect. These defects were repaired with ADM, and the clinical effects were observed. RESULT: Sixteen cases of hypopharynx tissue defect and 7 cases of neck skin tissue defect were repaired with ADM. One case in hypopharynx tissue defect group and 2 cases in neck skin tissue defect group undergone pharyngeal fistula postoperatively. CONCLUSION The repair of tissue defects in pharyngeal and laryngeal cancer with ADM had some advantages, such as good histocompatibility, low immune rejection, wide material sources and simple method. There were some differences in clinical effects between hypopharynx cavity defect and neck skin tissue defects, so the emphasis of the need to pay attention to is different in the clinical.

OBJECTIVE: Study the clinical characteristics, treatment results and prognostic factors of hypopharyngeal carcinoma. MMETHOD: A retrospective analysis was performed of 97 hypopharyngeal cases that were treated in Department of Dtolaryngology of our hospital from January 2008 to December 2012. 93 cases of them are male patients, and 4 cases are female patients. The tumors are originated from pyriform sinus(75 cases), posterior pharyngeal wall (16 cases) and post-cricoid area (6 cases). Of the 97 patients,21 patients were treated with partial hypopharynx resection (21. 6%), 7 were treated with partial laryngectomy+ partial hypopharynx resection (7. 2%), 53 were treated with total laryngectomy+partial hypopharynx resection (54. 6%), 12 were treated with total laryngectomy and total hypopharynx resection, gastric-pharyngeal anastomosis (12. 4%) and 4 were treated with total laryngectomy and total hypopharynx resection, enteric-pharyngeal anastomosis (4. 1%). Sixty-one cases undergo postoperative radiotherapy in Oncology. Use Chi-square test to do enumeration data analysis, the survival rate is calculated with the life table method, survival analysis with Kaplan-Meier method, parallel Log-rank test. Cox regression multivariate analysis model is used to find the factors affecting prognosis. RESULT: The follow-up rate of this group was 90. 7%. All patients' 1-year survival rate is 76. 0% , 3-year survival rate is 56. 0%, pathological lymph node metastasis rate is 71. 1%, occult lymph node metastasis rate is 19. 6%. Local recurrence rate is 21. 6%. The main reasons of death in patients include : cervical lymph node metastasis in 7 patients (21. 9%), local recurrence in 12 cases (37. 5%), distant metastases in 10 patients (31. 3%) and so on. Univariate analysis showed that tumor size (P<0. 01) and tumor T stage (P<0. 05) have impact on survival prognosis, no risk factors was found with Cox regression multivariate analysis. CONCLUSION Hypopharyngeal carcinoma is difficult to be found early, prone to recurrence and metastasis after operation, carefully chosen surgical excision and neck dissection, adjuvant postoperative radiation therapy is the main treatment strategy. Posterior pharyngeal wall carcinoma tend to have higer recurrence and metastasis rate than the other two types of hypopharyngeal caocinom, and treatment would cause much larger injury, so more attention should be paid to this type of hypopharyngeal caocinom.

Because of minimal donor site morbidity, adequate tissue, excellent clinical and functional results, the anterolateral thigh flap has become one of the most important tissue flaps which are used to repair the defects of head and neck. Generally, anterolateral thigh flap is mainly used to repair the maxillofacial defects in head and neck surgery. However, the anterolateral thigh flap is a better tissue flap for reconstruction of hypopharyngeal and cervical esophageal defects.
