RESUMO
Objective To study the clinical effects of different surgical treatments for laryngotracheal steno-sis .Methods The clinical data of 56 patients with laryngotracheal stenosis from July 2006 to July 2014 were ana-lyzed .Of all 56 cases ,7 cases were children ,49 cases were aducts ;9 cases underwent CO2 laser resection ,5 cases underwent temperature controlled radiofrequency ablation and 5 cases received laryngeal mold under self -retaining laryngoscope ,6 cases received Keel placement after laryngofissure ,23 cases received T -shape tube implantation af-ter laryngoplasty or tracheoplasty and 8 cases underwent end-to -end tracheal anastomosis after cervical tracheoto-my .Results All the patients had been followed up for 6 months to 2 years postoperatively .Thirty nine cases of 56 were cured after single-operation ,and 10 of 56 were cured after repeated operations .No one suffered from laryn-gotracheal stenosis again .Five cases failed and survived with tracheal tube .2 cases lost to follow -up .No people die or had complications .Among all cases ,5 cases with laryngeal mold and 8 cases with tracheal anastomosis were cured after single-operation .Among 9 cases with lasere scar removal surgery ,5 cases were cured after an operation ,3 cases were cured after two operations ,1 case failed because of laryngeal cancer recurrence .Among 5 case with tem-perature controlled radiofrequency ablation ,3 cases were cured afrter an operation ,1 case was cured after two opera-tions ,1 case had no effect .Among 6 cases with keel place -ment ,4 cases were cured after one operation ,1 case was cured after two operations ,1 case had no effect .Among 23 cases with T -shape tube implantation ,14 cases were cured after an operstion ,5 cases were cured after two and more operations ,2 cases had no effects and 2 cases were lost .Conclusion In order to improve the therapeutic effects of laryngotracheal stenosis ,the treatment strategy should be personalized according to the degree of stenosis ,the position of stemtis ,and the impairment of laryngotra-cheal framework .
RESUMO
Objective To investigate the clinical efficacy of microlaryngoscopy radiofrequency in treatment of patients with tongue base cysts. Methods 42 patients with tongue base cysts from January 2013 to December 2014 were randomly divided into treatment group and control group, the treatment group underwent microlaryngoscopy radiofrequency treatment, the control group underwent direct laryngoscopy under the tongue cystectomy, then the operation time, blood loss and postoperative recurrence rate were observed and recorded, and self-evaluation method using visual analog (VAS) to evaluate the effect of surgery. Results The operative time of treatment group was significantly shorter, and the blood loss was significantly less than the control group, the difference between the two groups was statistically significant (P 0.05); 12 months, the recurrence rate was 28.57% in the control group, the treatment group, the recurrence rate was 4.76%, the difference between the two groups was statistically significant (P < 0.05); Preoperative VAS score of the two groups have no significant difference, while after surgery, the VAS scores' difference was statistically significant, even treatment group compared with the control group VAS scores after surgery was statistically significant (P < 0.01). Conclusion Microlaryngoscopy radiofrequency in treatment of tongue base cysts have advantages of significant efficacy, safe and reliable, It's worthy of clinical promoting.
RESUMO
Objective To explore the clinical effect of temperature-controlled radiofrequency ablation of tonsil in the treatment of children obstructive sleep apnea hypopnea syndrome(OSAHS).Methods From January 2003 to January 2006,30 patients,confirmed OSAHS by polysomnography(PSG),aging from 3 to 10 years(mean:5.8 years)were treated by temperature-controlled radiofrequency ablation of tonsil,in which 21 cases with adenoidal hypertrophy were treated with adenoidectomy,and 3 of the 21 cases with secretory otitis media received auripuncture.Results Six months after the operation,the symptom of snoring and mouth breathing in all patients disappeared,tonsillar hypertrophy was kept in Ⅰ or Ⅱ grade,no pharynx stenosis was detected,and hearing was recovered to normal.After 1 year,20 cases were monitored with PSG,of which 10 cases were cured,8 cases showed apparent efficacy and 2 cases showed efficacy.Conclusions The temperature-controlled radiofrequency ablation of tonsil is an effective and safe technique in the treatment of children OSAHS.
RESUMO
Objective To evaluate the efficacy of tonsils and adenoid ablation by plasma-mediated temperature-controlled radiofrequency for obstructive sleep apnea hypopnea syndrome (OSAHS) in children. Methods From August 2005 to May 2007,43 cases with OSAHS received tonsillectomy and adenoid radical resection with Evac70 tool bit using a plasma-mediated temperature-controlled system. The clinical data of the patients were reviewed. Results The mean operation time was 16 minutes,ranged from 10 to 20 minutes. During the operation,the patients had a mean of 3 ml hemorrhage (1 to 10 ml). Compared with the preoperative examination,the patients showed significantly lowered AHI [(14.6?4.6) times/h vs (4.2?2.7) times/h,t=8.563,P=0.000] and OAI [(6.9?3.5) times/h vs (3.3?1.4) times/h,t=5.443,P=0.000] and increased minimum blood oxygen saturation [(85.7?4.4)% vs (99.7?0.2)%,t=-6.687,P=0.000]. Conclusions The ablation of the tonsil and adenoid using plasma-mediated temperature-controlled radiofrequency is effective and safe for children with OSAHS.
