OBJECTIVE To investigate a better surgical treatment for chronic otitis media.METHODS 106 patients with chronic otitis media were collected from hospital. We assessed effectss of ossicular chain reconstruction without incision of mastoid (method 1) and ossicular chain reconstruction with incision of mastoid (method 2).We compared therapeutic effect, complication, and surgical treatment between these two groups. Furthermore, we performed stratification analysis by normal or abnormal function of stapes, Eustachian and tendon of tensor tympani, using logistic regression model. RESULTS The improvement of hearing by method 1 and 2 were 85.71%, 68.00% (P=0.0296). The recovery rate of drying ear were 92.86%, 88.00% (P=0.3931). The proportion of continued tinnitus were 10.71%, 18.00% (P=2827). There were 85.71% and 36.00% samples with numeric pain score from 1 to 3 (P<0.0001). There were 89.29%, 24.00% samples with operation hour <2.0 hour (P<0.0001). For those patients with normal function of stapes, Eustachian and tendon of tensor tympani, the OR of method 1 were 2.91, 3.08 and 3.33 For those patients with abnormal function, the OR was 3.27, 2.89 and 1.33. CONCLUSION Ossicular chain reconstruction without incision of mastoid is a suitable surgical treatment for chronic chronic otitis media,it could improve hearing more effectively with entire debridement of the focus and shorter operation time.

Objective To research the influence of ulinastatin on body inflammatory factor levels in patients with severe burns, and provide the basis treatment of patients with severe burns. Methods A total of 94 patients from Jan 2010 to June 2013 were studied in this test. The control group was treated with basic therapy including fluid infusion, antishock, cutting scab surgery and early nutrition support while the treatment group was received ulinastatin on the basic of control. Routine blood, body inflammatory factors level change and APACHE II score were compared between the two groups, Results The number of WBC and neutrophil in treatment group was higher than control 1group (P <0.05), while the PLT was lower than control group (P<0.05). The APACHE II score was in the same level between the two groups before treatment, while the score of treatment group was obvious lower than control control group after 72hr (P<0.05). The TNF-α and IL-6 in treatment group was lower than control wihle the IL-2 and IL-10 was higher than control(P<0.05). Conclusion Ulinastatin played an important role in improving the patient's body state of inflammation, the patient's symptom and preventing complications.

Objective: To study the more safe and accurate guidance scheme of cone beam computed tomography (CBCT) in nasopharyngeal carcinoma. Methods: CBCT was regularly performed on 87 patients with nasopharyngeal carcinoma in Meizhou People's Hospital from November 2014 to August 2015. For each patient, 10 times CBCT scans were obtained pre-treatment. All the setup errors were obtained and analysed on the orientation X (left and right), Y (head and foot) and Z (vertical) axis. Results: With the increase of the number of CBCT scans, there was no statistically significant difference among the mean setup errors of the 10 times scans in X (left and right) and Y (head and foot) directions (all P > 0.05). And there was no statistically significant difference among the mean setup errors of 6 times scans in Z (vertical) direction, but from the beginning of the 7th, the systematic error in Z direction was increasing, the system error of the 7th, 8th, 9th, 10th time was 0.140, 0.292, 0.461, and 0.640 mm. Moreover, the difference of the mean systematic errors among the first 7 times was statistically significant (H = 15.232, P = 0.019), and the differences of the mean systematic errors among the first 8, 9 and 10 times were statistically significant (all P < 0.05). Conclusions Non-consecutive scans of CBCT could reduce the systematic and random errors. The appropriate frequency of application of CBCT based on the change law of setup errors is an ideal CBCT guidance scheme for nasopharyngeal carcinoma.

OBJECTIVE To analyze the varieties,causes and preventions of severe complications in OSAHS patients with delayed extubation after surgery.METHODS The clinical dates of 548 OSAHS patients with delayed extubation after surgery were retrospectively analyzed,in order to explore the incidence,reasons,and the prevention and control of severe complications.RESULTS There were 14 cases with severe complications in 548 OSAHS patients,including 1 case of septicemia,one case of nasal alar scar formation,one case of cerebral infarction,2 cases of massive hemorrhage,2 cases of tube dislocation,2 cases of ventilator resistance,2 cases of apnea,3 cases of ventilator-associated pneumonia.All of the14 cases recovered after dealing with the corresponding measures.No dead happened.CONCLUSION The incidence of complications in OSAHS patients with delayed extubation is relatively high.In order to improve the prognosis,more attentions should be paid to the airway care and manipulation in the course of treatment.When the complications happened,corresponding treatments should be done in time.If the patients' respiratory function and airway patency were normal,extubation as early as possible could reduce the incidence of complications.

OBJECTIVE: To determine the clinical value of transoral endoscopic adenoidectomy for the pediatric sinusitis. METHOD: Patients with chronic sinusitis and adenoid hypertrophy were divided into two group by undertaken with or without adenoidectomy, the operation group with 43 cases and the control group with 40 cases. Evaluation was performed in pretherapy and after 3 months therapy. Evaluation index included symptom scale for nasal obstruction and rhinorrhea, endoscopy score and CT score for chronic sinusitis. RESULT: There was a positive correlation (0.38) between the adenoid size and the symptom of nasal obstruction (P < 0.01). But there were no correlation between the adenoid size and the other index scores (P > 0.05). Whether in the operation group or the control group, all index scores in pretherapy were higher than in post-therapy (P < 0.05). After 3 month therapy, all index scores in the operation group were lower than the control group (P < 0.01). The decreased amplitude of all index scores in the the operation group were higher than the control group (P < 0.01). CONCLUSION Adenoidectomy combined with topical nasal treatment is one effective method for the pediatric sinusitis. Adenoidectomy play an important role in the treatment of pediatric rhinosinusitis.

Objective To analyze set-up errors for irradiation of nasopharyngeal carcinoma by using kilo-voltage cone beam computed tomography (kV-KBCT) scanning, and to calculate the external margin from planning target volume (PTV) of nasopharyngeal carcinoma. Methods A total of 150 nasopharyngeal carcinoma patients in Meizhou People's Hospital from December 2014 to November 2016 were treated by image-guided radiation therapy (IGRT), kV-KBCT, CT image scanning matcthed by bone and grey alignment. PTV of nasopharyngeal carcinoma was also calculated. Results According to PTV formula, the external distance before radiotherapy guided by grey alignment was 0.5 mm in X-axis, 0.4 mm in Y-axis, 0.8 mm in Z-axis. While the distance was 0.1 mm in X-axis, 0.5 mm in Y-axis, 1.7 mm in Z-axis guided by bone alignment. After radiotherapy, the external distance guided by grey alignment was 0.4 mm in X-axis, 0.5 mm in Y-axis, 0.9 mm in Z-axis. While the distance was 0.1 mm in X-axis, 0.9 mm in Y-axis, 2.0 mm in Z-axis guided by bone alignment. There was no significant difference in set-up errors of 3 directions and 2 aligned ways before and after treatment.Conclusions The PTV within 3 mm is safe when IGRT is used for directing radiotherapy of nasopharyngeal carcinoma,and kV-KBCT is an effective image equipment.
