Value of controlled synechiae technique on maintaining stability of middle turbinate in endoscopy surgery / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To explore the method of the controlled synechiae technique to maintain the stability of middle turbinate (MT), reduce the incidence of middle meatus synechia formation and improve the treatment effect of endoscopy surgery.@*METHOD@#Eighty-six patients with chronic sinusitis were randomly divided into control group and treatment group in this study. In control group, the patients received extended nasal packing in middle meatus until 1 week after surgery. In treatment group, the patients received the controlled synechiae technique.@*RESULT@#The MT position was described as stable, slight drifting laterally and synechia formation. And the incidence of synechia between MT and the nasal lateral wall was 29.4% and 14.9% in control group and treatment group,respectively. The differences were significant (P < 0.05).@*CONCLUSION@#For those patients with anatomic variation, destruction or weak supporting structures resulted from previous surgery, the controlled synechiae technique is very useful in preventing lateralization of the middle turbinate after endoscopy surgery.

Compare the value of video laryngoscope in localization diagnosis of upper airway stricture in obstructive sleep apnea-hypopnea syndrome between awake and drug-induced sleep / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To compare the value of video laryngoscope in localization diagnosis of upper airway stricture in obstructive sleep apnea-hypopnea syndrome (OSAHS) between awake and drug-induced sleep.@*METHOD@#Ninety-eight patients of OSAHS were examined with video laryngoscope to locate the upper airway stricture under awake and Midazolam-induced sleep.@*RESULT@#The several stricture levels under awake was 58.2% and it was 77.5% under drug induced sleep.@*CONCLUSION@#Several stricture levels of upper airway were founded in most of the patients of OSAHS. The upper airway stricture levels was more in the sleep than in the wake.

The value of video laryngoscope in localization diagnosis of upper airway stricture in obstructive sleep apnea-hypopnea syndrome during drug-induced sleep / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate the value of video laryngoscope in localization diagnosis of upper airway stricture in obstructive sleep apnea-hypopnea syndrome (OSAHS) during drug-induced sleep.@*METHOD@#One hundred and thirty two patients with OSAHS were randomly divided into group A and B in this study. In group A, the patients were examined with video laryngoscope to locate the upper airway stricture under midazolam-induced sleep. In group B, the patients had conventional physical examination and video laryngoscope when awake. And the operation plans of both groups were made based on the localization diagnosis results.@*RESULT@#In group A, 72.1% patients have several stricture levels and in group B only 33.8%. The patients was followed up time more than 6 months, and the cure rate, the excellent effective rate, and the total effective rate of group A were significantly higher than those in group B respectively (P<0.05).@*CONCLUSION@#Most patients of OSAHS have several stricture levels of upper airway under Midazolam- induced sleep. Localization diagnosis of upper airway stricture in patients with OSAHS with video laryngoscope before operation can improve the cure efficiency significantly.
