Plain X-ray for locations of intracochlear electrode arrays during cochlear implantation / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To evaluate the position and shape of inserted electrode arrays by plain X-ray during cochlear implantation.@*METHOD@#Cochlear view of implanted electrode arrays by plain X-ray were observed during operation in 54 patients received cochlear implant.@*RESULT@#The image in cochlear view could provide the information about position and shape of inserted electrode arrays. The spiral-shape electrode arrays without distortion and folding were found in 52 cases. The complete insertion of intracochlear electrode in these patients were confirmed by surgery. Of 54 cases, the other 2 cases showed improper position and C-shape of intracochlear electrodes, one was partial insertion and the other was bending inside the cochlea. The bending electrode array was reinserted immediately during operation.@*CONCLUSION@#Routine plain X-ray after inserted electrode during operation was a best way of knowing the shape and depth of the electrode array, especial for the difficult cochlear implantation, and also could avoided anesthetization again.

Analysis of the reason for the adhesion of vocal cord after CO_2 Laser laryngeal surgery / 临床耳鼻咽喉头颈外科杂志

Objective:To investigate the reason for the adhesion of vocal cord after CO_2 Laser laryngeal surgery.Method:One hundred and nineteen patients who were untaken CO_2 Laser laryngeal microsurgery.Result: Among 119 cases,9 cases of bilateral vocal cord paralysis, 42 cases of vocal cord polyps and 3 cases of precancerous laryngeal lesions did not show vocal cord adhesion after CO_2 Laser laryngeal microsurgery.Contrarily, one of 5 cases with laryngeal stenosis, 5 of 41 cases with laryngeal papilloma and 6 of 19 cases with laryngeal carcinoma shew the adhesion of vocal cord after CO_2 Laser laryngeal microsurgery.Conclusion:Through selecting the appropriate patient and surgery spot, processing correctly during and after surgery, using the suitable dosage of laser and reducing the heat radiation, the adhesion of vocal cord can be avoided after CO_2 Laser laryngeal surgery.
