This study was conducted to investigate changes of airway size, tongue and hyoid position following orthognathic surgery in mandibular prognathism, and how they are adapted to new environment in tine dependent manner. 37 patients, who had recieved orthognathic surgery, were selected for this study. lateral cephalogram of each patient was taken at preoperation, immediate postoperation, and over 6 month after operation, and were traced and analyzed. The findings of this study were as follows: 1. The size of airway was not changed at PNS and Epiglottis level after operation, but it was changed slightly at 2nd cervical vertebra level. 2. The hyoid was moved inferoposteriorly at immediate postoperation, and then it shifted toward preoperative position, but it remained slightly inferoposterior position. The distance from hyoid to genial tubercle decreased continuously. 3. The position of tongue was moved inferoposteriorly at immediate postoperation, and then it shifted toward preoperation position, but the root of the tongue remained inferoposteriorly. 4. The distance between tongue and hyoid was increased at immediate postoperation and slightly decreased during follow-up period. 5. The change of the mandibular position was not significantly correlated with changes of airway size, hyoid position, tongue morphology and tongue position.

OBJECTIVE: To evaluate the effect of the coblation under endoscopy on epiglottis cyst. METHOD: One hundred and ninety-three patients with epiglottis cyst were treated with coblation under endoscopy. Follow-up study was performed from 1 month to 6 months after treatments. RESULT: All 193 cases with epiglottis cyst were primary cured without serious complication and the cure rate was 100%. Moreover, the minor hemorrhage (1-5 ml) was observed. CONCLUSION The coblation under endoscopy on epiglottis cyst was safe, effective and minimally invasive.

In order to evaluate the availability of the lateral horizontal laryngectomy and anaplasty of epiglottis to treat some patients with specific supraglottic carcinomas and hypopharyngeal carcinomas, 17 cases of laryngeal and hypopharyngeal carcinomas were retrospectively analyzed, whose tumors were located at the lateral margin of epiglottis, aryepiglottic fold, medial wall of piriform fossa and were treated by the lateral horizontal laryngectomy and anaplasty of epiglottis. The results showed that all cases took food by mouth in postoperative 9-14 days and subjected to decannulation in postoperative 9-15 days. Three cases had postoperative hoarse voice. The free-disease survival rate of 3 years was 71.4% in 14 cases followed up after the first surgical therapy, and the overall free-disease survival rate of 3 years was 85.7% after the second surgical therapy. It was concluded that the manipulations of the lateral horizontal laryngectomy and epiglottiplasty were simple. It could alleviate the postoperative symptoms of aspiration and bucking remarkably and shorten their postoperative recovery time, yet does not lower the survival rate of patients if laryngocarcinoma or hypopharyngeal carcinoma cases were properly selected.

OBJECTIVE: To investigate the therapeutic effects of coblation treatment via endoscopy in epiglottic benign tumors. METHOD: Retrospective analysis was carried out in 128 patients with epiglottic benign tumors who underwent coblation treatment via endoscopy. The complications and therapeutic effect were analyzed. RESULT: The effective rate of treatment was 100% in cyst of epiglottis and in papillary epithelioma, and was 96.36% in hypertrophy of lingual tonsils. The pseudomembrane 1 w after operation. Postoperative pain is slight. There were no complications such as dyspnea, bleeding and infection. CONCLUSION Radio frequency coblation via endoscopy will be applicable in the therapy of epiglottic benign tumors.

OBJECTIVETo present the efficacy of minimally invasive technology of coblation in the treatment of infant epiglottic cyst.

METHODSThe clinical data of 30 infants with epiglottic cyst treated between January 2008 and January 2011 were reviewed retrospectively. All infants with epiglottic cyst were treated with the ArthroCare ENT Coblator II Surgery System after being checked completely.

RESULTSAll 30 patients were successfully operated. The blood loss was less than 2 ml during the surgery. The infants recovered without any complications and were discharged from hospital in 10 days after surgery. The clinical symptoms improved significantly or disappeared. No patients showed recurrence during followed-up over 6 months.

CONCLUSIONThe advantage of the minimally invasive technology of coblation in infant epiglottic cyst was less bleeding, little injury and postoperative organization reaction.

OBJECTIVE: To investigate an individualized operative modality of partial laryngectomy for suprahyoid epiglottis centered epiglottic carcinoma. METHOD: Eleven cases of epiglottic squamous carcinoma which primarily focused in the suprahyoid region were included. Preoperative CT indicated that obvious margin with low density existed in the pre-epiglottic space in 3 cases, and pre-epiglottic space were involved in 8 cases, among which the arytenoid region were involved in 2 cases. An individualized partial laryngectomy was manipulated beyond the safe margin, an arytenoid epiglottic fold-plasty was performed and the remaining epiglottis was fixed to the tongue base. Adjuvant postoperative radiotherapy and chemotherapy were applied to all patients and the follow-up time lasted from 1 to 6 years with mean time of 3 years and 6 months. RESULT: One patient died of recurrence in the tongue base after one year postoperatively, one was lost to follow-up 2 years after surgery. The overall 3-year survival rate was 81.8%. Nine patients were free from tracheal cannulation within one year postoperatively and the other two patients went on with tracheal tube assisted respiration. Aspiration gradually disappeared within 1-3 months. CONCLUSION Individualized partial laryngectomy in treatment of epiglottic carcinoma could preserve more laryngeal tissue and result in better laryngeal function preservation.
