作者在过去5年中,用冷冻手术治疗21例喉乳头状瘤,以往均经手术切除,不久复发。共进行55次直接喉镜及冷冻外科,16例乳头状瘤已消失。用同法治疗喉癌17例,13例肿瘤已消失。进行儿童喉部冷冻手术,必先作气管切开术,因术后1小时内,均有呼吸困难。成人接受此种手术者,应留院观察1天,但很少超过2天。如乳头状瘤较多、较大,可先用喉钳切除,仔细止血后,用液氮直接喷入,每次一分钟,进行2或3次,每次待其完全融化后,再行二次,一般2次1分钟,1次30秒钟即可,如气管内亦有病变,先用凡士林纱条填于肿瘤之下,然后用同法喷治其中的乳头状瘤。作者认为如喉乳头状瘤经冷冻手术后,有2或3处新病变复发,虽然为时只有3—4个月,
In the past 5 years, the authors used cryosurgery to treat 21 cases of laryngeal papilloma. All patients were surgically removed and relapsed soon. A total of 55 direct laryngoscopy and cryosurgery were performed, and 16 papillomas had disappeared. With the same method in 17 cases of laryngeal cancer, 13 cases have disappeared. For cryosurgery of children, tracheotomy must be performed first, and dyspnea is difficult within 1 hour after surgery. Adults who undergo this type of surgery should stay in the hospital for observation for 1 day but rarely exceed 2 days. If the papilloma is large and large, it can be removed with a pliers first. After the hemostasis is carefully stopped, spray it directly with liquid nitrogen, one minute at a time, 2 or 3 times, and wait for it to completely melt. Times, usually 2 times 1 minute, 1 time 30 seconds can be, such as lesions in the trachea, first filled with Vaseline gauze under the tumor, and then use the same method to treat the papilloma. The authors believe that if a laryngeal papilloma undergoes cryosurgery, there are 2 or 3 new lesions that recur, although it lasts only 3-4 months.
