Investigation of clinical application of the self-made curved laryngoscope / 中国耳鼻咽喉头颈外科

ABSTRACT

OBJECTIVE To discuss the clinical utility of the self-made curved laryngoscope.METHODS Clinical data of 198 patients with vocal cord polyps from September 2012 to October 2014 was analyzed retrospectively in which 99 cases were treated under the self-made curved larngoscopic surgeries (curved laryngoscope group) and 99 cases were treated by microlaryngoscopic surgeries (microlaryngoscope group).The duration of follow-up was 3 months in all patients.The clinical efficacy, times of inserting laryngoscope, glottic exposure and operation complications of two kinds of operations were observed and compared.RESULTS The total clinical efficacy in curved laryngoscope group showed no significant difference as compared with that in microlaryngoscope group. But for patients with difficult laryngeal exposure,the efficacy of curved laryngoscopic surgery was significantly better compared with that in the microlaryngoscopic surgery group. The results of times of inserting laryngoscope, glottic exposure and operation complications in the self-made curved larngoscope group were all better than those in microlaryngoscope group (P <0.05). CONCLUSION The operation under the self-made curved laryngoscope is a minimal invasive procedure to the laryngeal mucosa, with such more advantages like clear view of operation field and accurate management to the lesion tissue.Furthermore, the self-made curved laryngoscopic surgery is the first choice for the treatment of patients with difficult laryngeal exposure.
