Efficacy Of Minimally Invasive Surgery For Early Glottic Carcinoma And Precancerous Lesions

Objection: The retrospective analysis of the treatment effect of theminimally invasive surgery and traditional hand treatment for earlylaryngeal cancer （glottic）and precancerous lesions.Methods: Earlylaryngeal cancer （glottic） and precancerous lesions of OtolaryngologyHead and Neck Surgery, admitted123cases of October2011-2012inDecember, the Second Clinical Medical College of Jilin University. Lineof coblation ablation in28patients, CO₂laser resection of50patients,traditional the throat cracked resection in45patients. All patients withpostoperative outpatient to review electronic laryngoscope and telephonefollow-up.Result: In this study, patients with early laryngeal mean operativetime was8.72±1.53in the operative time aspects of coblation. CO₂laser group were14.93±1.71. Surgery operative time was121.18±5.29.And other ions were excellent in the CO₂laser group, minimallyinvasive group better than the surgery group. The VSA rated: coblationcoblation group is equal to the CO₂laser group（P=0.49P＞0.05）,while the minimally invasive group better than the surgery group （P=0P<0.05）. Average length of stay minimally invasive group were excellent with the surgery group （P=0.00P<0.05）. The mucosalrecovery: coblation group with the CO₂laser between the two groupswas statistically significant （P=0.00P <0.05）, the minimally invasivegroup and the surgery group difference was statistically significant （P=0.00P <0.05）. Early laryngeal cancer recurrence, minimally invasivesurgery and conventional surgery （recurrence within2years） was notstatistically significant. Conclusion: The coblation ablation and CO₂laser for the treatment of early laryngeal （glottic Tis T1T1b） andprecancerous lesions compared to the traditional open surgerypostoperative survival and recurrence rate are basically similar.Therefore, both of which is also an effective means. Advantages ofminimally invasive surgery:（1） under the microscope surgical cuttingaccurate, less trauma, less bleeding, the operative field clear;②surgerycaused local edema and mild, with little risk of postoperative laryngealedema asphyxiation without tracheotomy; verbal communication.③after surgery you can eat by mouth, does not require nasogastric feedingand postoperative can-verbal communication, is conducive to thepsychological rehabilitation of patients;④Shorter operative time, lessinvasive,less painful, faster postoperative recovery;⑤fewerpost-operative complications, compared with conventional open surgery,not the neck wound infection pharyngeal fistula, scarring and othercomplications, postoperative breathing, swallowing and phonation recovery and higher quality of life. In addition, the RF Knife front endcan freely bending angle can be self-regulation, compared to the CO₂laser cutting can be completely hidden lesions, it is more suitable for thelesion infiltrating into the lesions of the anterior commissure.
