OBJECTIVE: To investigate the clinical and pathological features of solitary pterygoid benign lesions, as well as the treatment and outcome of endoscopic surgery. METHOD: We retrospectively analyzed clinical data of 4 patients with pterygoid benign lesions in our department. High resolution CT and enhanced MRI were performed before the operations, then endoscopic surgeries were carried out under the circumstance of general anesthesia. After a follow-up in 12 months to 48 months, nasal endoscopy and MRI examination were performed. Therefore we are able to understand the situation of operations and postoperative recurrences, and to inquire about the changes of symptoms and the relief of symptoms before and after surgery. RESULT: From the Pathological diagnosis, it showed 2 cases of cystic lesions, 1 case of spindle cell lipoma, 1 case of inflammatory lesion. Postoperative follow up showed scar formation, smooth surface, no recurrence, and no new symptom. Nasal obstruction is relieved after the surgery, and no changes in the sympotoms of headache were observed. CONCLUSION The combination of high resolution CT with enhanced MRI isimportant for ascertaining the location, extent and nature of the pterygoid lesions. Endoscopic surgery is a minimally invasive, safe, and effective method for the treatment of solitary pterygoid benign lesions.

OBJECTIVE: To investigate the long term clinical effect of budesonide treatment in middle meatus for chronic rhinosinusitis(CRS) following endoscopic sinus surgery (ESS). METHOD: A total number of 53 patients with CRS received ESS were divided into two groups according to budesonide treatment: budesonide-treated group with 21 cases (39.6%) and control group with 32 cases (60.4%). Gelatin sponges soaked with 1 ml budesonide suspension were put in middle meatus in budesonide-treated group, while only gelatin sponges were put in middle meatus in control group. Visual analogy score (VAS), sino-nasal outcome test-22 (SNOT-22) and Lund-Kennedy endoscopic scale were carried out before ESS and two years after ESS. RESULT: In budesonide-treated group, there were a statistical difference before and after ESS in the VAS, SNOT-20 and Lund-Kennedy score (P<. 05). In control group, difference was also significant in VAS, SNOT-20 and Lund-Kennedy score before and after ESS (P < 0.05). The VAS gap of post-operative and pre-operative in two groups are significantly different (P<. 05). However, there was no significant difference in the SNOT-20 and Lund-Kennedy endoscopic scale gap before or after the operation between two groups. CONCLUSION It is safe, convenient and practicable to perform budesonide treatment in middle meatus following ESS, which can significantly ease the post-operative discomfort of nose.

BACKGROUND: A retrospective review of the surgical treatment of refractory chest tumors involving the heart or large vessels with cardiopulmonary bypass (CPB). METHODS: To summarize 11 cases of chest tumor patients who had undergone cardiopulmonary bypass surgery from January 2008 to May 2017 in our hospital, and analyze the general condition, clinical characteristics, treatment methods, postoperative hospitalization time, complications and follow-up results of all patients. RESULTS: All 11 patients were operated with cardiopulmonary bypass. Total resection of tumors in 8 cases and most of the excision in 3 cases. 1 case of left atrial metastatic leiomyosarcoma were excised in the left atrium, and then the right lung resection was performed. 1 case of left lung central lung cancer resection through the median sternum incision. 2 cases underwent pulmonary artery repair at the same time, 3 cases underwent partial pericardiectomy and 3 cases underwent pulmonary wedge resection at the same time. All the patients were effectively relieved after the operation. No death rate in hospital and 30 days after operation. 3 cases of postoperative pulmonary infection were recovered after the treatment of antibiotics. 1 case of lymphoma relapsed 6 months after surgery and died one year later. 1 case of pericardial fibrosarcoma had local recurrence and extensive metastasis at 13 months after operation, and died after 15 months. 1 case of pulmonary leiomyosarcoma were found to have local recurrence 15 months after the operation and were relieved after chemotherapy. The remaining 8 patients survived, and no obvious recurrence and distant metastasis were found in the computed tomography (CT) examination. CONCLUSIONS The CPB assisted surgical treatment can be performed for patient of refractory chest tumors involving the heart or large vessels. It can improve the surgical resection rate of refractory chest tumors, effectively alleviate the effects on respiratory and circulatory functions, and significantly prolong the survival period of these patients.

OBJECTIVETo investigate the clinical effect of nasal packing with or without Merocel after endoscopic sinus surgery (ESS) in short and long term.

METHODA total of 112 patients with chronic rhinosinusitis who received endoscopic sinus surgery were randomly divided into two groups: packed group and non-packed group. In packed group, there were 37 cases, of which 10 cases were combined with allergic rhinitis and 11 cases received correction of nasal septum at the same time. In non-packed group, there were 75 cases, of which 15 cases were combined with allergic rhinitis and 26 cases received correction of nasal septum at the same time.Visual analogue score (VAS), Nasal bleeding and sinonasal outcome Test-22 (SNOT-22) were used to evaluate the clinical effect between two groups in short and long term respectively.

RESULTThe VAS of nasal obstruction, rhinodynia, dysphoria, epiphora, itching, sneeze, headache and facial pain in non-packed group were significantly lower than those in packed group (P < 0.05). Within 48 hours after ESS, the amounts of nasal bleeding were 0-45 ml (median 3 ml) in packing group and 0-18 ml (median 2 ml) in non-packing group. There were significant difference between two groups (Z = -3.54, P = 0.00). The difference value of postoperative and preoperative SNOT-22 of the packed group was 38.47 ± 20.25 and the non-packed is 41.03 ± 22.73 six months after ESS (t = 0.58, P = 0.56). Each group had one case of nasal adhesion. And as for middle turbinate dislodgement, there was one case in the packed group and two cases in the unpacked group. There was no case of nasal septum hematoma in the packed group, but two cases in the un-packed group. The results showed that there was no significant difference of clinical effect between the postoperative packing and unpacking groups.

CONCLUSIONSIt is safe and practicable to manage chronic rhinosinusitis without nasal packing after ESS, which in short term not only decrease discomfort, but also reduce nasal bleeding. Also, there is no significant difference of clinical effect between the postoperative packing and unpacking groups in long the term.
