To examine the postoperative complaints and complications of microlaryngoscopic surgery (MLS) performed at a facility specializing in voice disorders.
The subjects were 550 patients who underwent MLS over a period of 2 years and 6 months starting in 2014; they were investigated retrospectively based on surgical and medical records.
Postoperatively, some complaints and complications were identified in 66.0% of the subjects; sore throat was reported by 40.0%, which was the highest rate of complaints among all subjects. Tongue-related complications (numbness of the tongue, taste disorder, tongue pain, and hypoglossal nerve palsy) were observed in 16.9% of all cases, which was a relatively high rate. A median duration of 4 days was required to recover from tongue numbness (1.0 and 11.0 days for the 25th and 75th percentiles, respectively), while recovery from a taste disorder involved 4 days (4.0 and 14.3 days); a relatively long period was required for healing. However, 25% of taste disorders and 21% of tongue numbness cases required more than 2 weeks to recover; all cases recovered eventually. Almost all complaints and complications were temporary. Moreover, only three cases (0.55%) of tooth damage were irreversible. No other serious complications were observed.
In previous reports, we examined the complications of MLS conducted by phonosurgery specialists at our hospital, which is a facility that specializes in voice disorders. An unexpectedly large number of patients complained of some symptoms after the operation. Because tongue-related complications tended to have a long healing duration, we think that preoperative explanations are important. We believe that the results of this study provide new insights into the incidence of complications and complaints after MLS and the healing duration.
研究在专门从事嗓音疾病的机构中进行的显微镜声带手术（MLS）的术后并发症和投诉。
回顾性分析 2014 年 6 月至 2 年 6 个月期间在我院接受 MLS 的 550 例患者的手术和病历记录。
术后，66.0%的患者出现了一些投诉和并发症；所有患者中，咽痛发生率最高，为 40.0%。所有病例中，舌相关并发症（舌麻木、味觉障碍、舌痛和舌下神经麻痹）发生率为 16.9%，相对较高。舌麻木的中位恢复时间为 4 天（第 25 和 75 百分位数分别为 1.0 和 11.0 天），味觉障碍的恢复时间为 4 天（4.0 和 14.3 天），需要较长的时间才能愈合。然而，25%的味觉障碍和 21%的舌麻木需要超过 2 周才能恢复，所有病例最终都恢复了。几乎所有的投诉和并发症都是暂时的。此外，只有 3 例（0.55%）的牙齿损伤是不可逆的。没有观察到其他严重并发症。
既往我们研究了我院嗓音疾病专门机构的嗓音外科医生开展的 MLS 并发症，发现术后有大量患者抱怨出现一些症状，出乎意料。由于舌相关并发症的愈合时间较长，我们认为术前解释很重要。我们认为本研究的结果为 MLS 术后并发症和投诉的发生率以及愈合时间提供了新的认识。
