OBJECTIVE: To explore the clinical efficacy of functional endoscopic sinus surgery (FESS) associated with radiofrequency ablation on chronic sinusitis. METHOD: Fifty-four patients with chronic sinusitis were divided randomly into two groups: the study group and the control group, The study group received FESS associated with inferior turbinate lateral fracture and radiofrequency ablation treatment, while the control group received FESS associated with inferior turbinate lateral fracture treatment. RESULT: The SNOT-20 score, Lund-Kennedy score, mucociliary clearance time and nasal airway resistance of the patients in the two groups after treatment were significantly improved than those before treatment (P < 0.05), and the sense of nasal congestion, headache and face pain, purulent rhinorrhea, postnasal drip, and other symptoms were also relieved. After treatment, the scores of SNOT-20 and the scores of Lund-Kennedy in the study group were significantly lower than those in the control group (P < 0.05), but no significant difference was found in mucociliary clearance time between the two groups after treatment. CONCLUSION FESS associated with radiofrequency ablation surgery is safe and effective for chronic sinusitis.

OBJECTIVE In order to explore the site of the nasal valve.METHODS The distribution of nasal airway resistance were studied in normal adults, and patients with chronic rhinitis,patients underwent partial inferior turbinectomy,patients with the deviation of nasal septum and the patients underwent correction of the nasal septum.RESULTS Before the nasal mucosa decongested,the site of the most effect on the NAR was located in pyriform fossa in normal adults. After the nasal mucosa decongested,the site of the most effect on the NAR was located in the ostium internum.The most significantly site which effect on the NAR were pyriform fossa and the ostium internum before and after operation in the patients who suffer from chronic rhinitis.The site of the most effect on the NAR was in the place of deviation of the nasal septum before operation and in the pyriform fossa after operation.CONCLUTION The result suggested that the site of the nasal valve is changeable and related to the condition of contraction and relaxation of the nasal mucosa and the extent of nasal patency.

Objective To determine whether or not the bacterial DNA which was detected by PCR comes from viable bacteria.Methods Observe the effection of middle ear effusion(MEE) on DNA viscosity and enzymatic digestion of DNA.Results The middle ear effusion and DNA are stable and DNase 1 rapidly digests DNA,The effusion does not seem to degrade DNA.The middle ear effusion signifcantly inhibits DNase 1.Conclusions Middle ear effusion provides an inhibition of the enzymatic digestion of purified DNA.Thus any DNA found in effusion by PCR techniques could well be fossilized remains and chronic otitis media with effusion may not be the bacterial infection that recent studies have suggested.

OBJECTIVE: To compare the effects of bupivacaine, lidocaine and saline injections in alleviating post tonsillectomy pain. METHOD: We recruited 60 patients into the study. All subjects were randomly allocated into 3 groups. Group 1 received 0.9% sodium chloride (saline group), group 2 received 0.25% bupivacaine (bupivacaine group) and group 3 received 2% lidocaine (lidocaine group), infiltrated around each tonsil. Pain was evaluated with McGrath's face scale. RESULT: The postoperative pain scores at 2 and 6 hours were similar among the groups (P>0.05). The pain scores in the bupivacaine group were lower than those in the saline group at 12 h (P<0.05). The pain scores in the bupivacaine and lidocaine groups were significantly lower than those in the saline group from 18 to 24 hours until day 7 (P<0.05). There was no difference between the bupivacaine and lidocaine groups (P> 0.05). CONCLUSION Local infiltration of bupivacaine is a relatively and safe effective method and is equivalent to use of lidocaine for post tonsillectomy pain.

Objective:To study the distribution of allergens in our district and the correlation between skin prick test with antigen and nasal provoking test in patients with allergic rhinitis.Method:A total of 1 400 cases with allergic symptoms and signs underwent skin prick test with standardized aeroantigens provoking by AllergoPhamar Company. The patients allergic to Dermatophagoides with different scale of the skin prick test were taken nasal provoking test in order to evaluate the correlation between skin prick test and nasal provoking test.Result:One thousand and eighty-eight(78%) cases showed a positive result in skin prick test.The percent of patients with positive skin prick test were as follows: 462 cases of Dermatophagoides pleronyssinus, 428 cases of Dermatophagoides farinae. Positive perennial aeroantigens were 52.2%(568),positive seasonal aeroantigens were 35.7%(388). All the patients of the scale of skin prick test was +++ and ++++ were positive. There are 29 patients were positive with nasal provoking test which the scale of skin prick test was ++. There are 21 patients were positive with nasal provoking test,which the scale of skin prick test was +.Conclusion:The correlation between skin test with antigens and nasal provoking test in patients whose positive scale were +++ and ++++. There are false positive in the patients whose positive scale were + and ++. The specific immunotherapy should consider the scale of the skin prick test and eliminate the false positive before the therpy.
