Laryngoscopy combined with microwave treatment of 65 cases of vocal cord polyp
Jie (Danyang City People's Hospital of Otorhinolaryngology. Danyang 212300) [Key words] electronic laryngoscope; microwave; vocal cord polyps. [CLC] R767.4 [Document code] B [Article ID] 1671-7783 (2005) 02-0167-0l video laryngoscope combined with microwave treatment of vocal cord polyps,[link widoczny dla zalogowanych], operating under direct vision,[link widoczny dla zalogowanych], positioning accuracy, time is short, our department from January 2000 to 2003 with the treatment of l2 months 65 cases of vocal cord polyps, and the early adoption of e-laryngoscopic vocal cord polyp biopsy forceps were 74 cases, satisfactory results are reported as follows. 1.1 Case 1 and method of the object under video laryngoscope combined with microwave treatment of vocal cord polyp is A group of 65 patients, 21 males and 44 cases female, aged l9 ~ 76 years, mean 28.6l years. Lesions: 21 cases left and right cases with 28 cases, bilateral l6 cases. Randomly select 1999 年 1 January 2002 under the l2 month electronic laryngoscope vocal cord polyp biopsy forceps cases 74 cases for the B group, 74 patients, male 26, female 48 cases, aged l7 ~ 75 years old, average 29 .36 years old. 24 cases of lesions on the left and right cases 31 cases, bilateral l9 cases. The main symptoms are all patients were hoarseness, sore throat, foreign body sensation and speech difficulty, all cases were confirmed by pathology. 1.2 A set of instruments used storzkaRL electronic laryngoscope,[link widoczny dla zalogowanych], ENDSkope light source and camera system, biopsy system. Justl03 endoscopic computer image processing system (Jiangsu Jetstar University Technology Development Company) and Nanjing Kia Microwave Technologies MTC-4-type microwave therapeutic instrument. 1.3 All surgical patients are under local anesthesia, 1% tetracaine pharyngeal spraying, intratracheal instillation of 1% ropivacaine, total no more than 2ml, anesthesia successful take seats at the mouth into the video laryngoscope The pharynx to the larynx, glottic visualization shows the lesion site to biopsy forceps after removal of DU patients microwave probe needle biopsy in electronic laryngoscope into the opening, to be dressing on the wound, time 1 ~ 2S, power is 50W, broad-based polyps, first burning and then removal of lesions. Tissue were removed for inspection. Images collected before and after operation, printing reports, gag patients after two weeks, the conventional aerosol inhalation. B: In addition to not using microwave, the other dealing with the A group. 2 Results All patients were followed up for 1 to 3 years. Healing: normal vocal cords, larynx local lesion disappeared. Markedly: normal vocal cords, larynx local lesions disappeared. Effective: sound was better, but throat local lesions is not fully disappear. Invalid: no change in hoarseness and throat local lesions did not disappear. A group and B group effect in Table 1. Table 1 Comparison of patients in two groups of fish in the whole plastic plastic check Sook Sook A group 65421751B group 743,418,175 total effective rate (%) 98.593.2 seen from Table 1, A total effective rate 98.5%,[link widoczny dla zalogowanych], B group 93.2%. Two sets of data are statistically significant difference (P <0.05) 3 to discuss a variety of noxious stimuli can cause vocal cord blood expansion, enhanced permeability, local edema, fibrosis, and to the further degeneration, the occurrence of nodules, polyps and other diseases. Surgical treatment of medical therapy feasible, there is indirect support laryngoscope laryngoscope under general anesthesia surgery surgery surgery under video laryngoscope. The latter has outpatient surgery, zoom out, as the low cost advantages. Electronic laryngoscopic vocal cord polyps, full anesthesia,[link widoczny dla zalogowanych], patients with good, clear view under the lesions enlarge, accurate resection of the lesions, the patient less pain. In practice, sometimes vocal cord lesions wider base, less light, after removing the focus of the whole, then cut the edge sometimes, such as vocal cord muscle fiber damage normal tissue, some vocal cord polyps hard texture, difficult forceps biopsy forceps, affecting operating time. So I Section microwave ablation needle probe to be wound dressing, and sometimes also in the first microwave ablation lesion base, or to reduce the base lesion rough, re-excision biopsy forceps. A group and B group by comparing the difference was statistically significant efficacy. But special attention is based on microwave properties, that tissue to absorb microwave energy tissue damage caused by heat, when operated under the strict control laryngoscope series of energy and time, we realized the power 50W, time should not exceed 2S. While only a short exposure to burning the edge of the lesion, needle-shaped probe can not be inserted to prevent the normal vocal cord tissue damage. [
