目的探讨环状气管切除术对成年女性嗓音的影响。方法对14例因慢性呼吸道阻塞并特发性喉气管狭窄而行环状气管切除术的女性患者进行手术前后的语音记录，年龄35~69岁，平均53岁。用语音分析软件对录音进行分析。测量方法包括：一个元音在舒适的音调下的平均基频和响度(F0)、连接语音的平均F0(即说话时的F0)、音高范围(F0范围)和最大发声时间。采用语音残障指数的自我评估方法。结果平均发音F0由186赫兹降至165赫兹，平均下降21赫兹(p=0.04)。7例患者术后说话频率F0<160 Hz。平均持续元音频率也下降了32赫兹(p=0.03)。F0音域平均减少了5.9个半音，从21.5降至15.6(p=0.05)。最大发声时间无明显变化。术后平均语音残疾指数为21.9分。结论环状气管切除术对成年女性嗓音有明显影响。它通常将说话声音的音调降低到男性音域，并缩小声音的音调范围。在术前咨询时，应与患者讨论可能伴随这一过程而来的声音变化。
Objectives We measured the effects of cricotracheal resection on the adult female voice. Methods Voice recordings of 14 women (mean age, 53 years; range, 35 to 69 years) who underwent cricotracheal resection for chronic airway obstruction associated with idiopathic laryngotracheal stenosis were acquired before and after surgery. The recordings were analyzed with voice analysis software. The measures included the mean fundamental frequency of a sustained vowel at a comfortable pitch and loudness (F0), the mean F0 of connected speech (ie, speaking F0), the pitch range (F0 range), and the maximum phonation time. Self-assessment measures of the Voice Handicap Index were taken. Results The mean speaking F0 lowered significantly, by 21 Hz, from 186 Hz to 165 Hz (p = .04). In 7 patients, the speaking F0 was below 160 Hz after the operation. The mean sustained vowel frequency also dropped by 32 Hz (p = .03). The F0 range was reduced by an average of 5.9 semitones, from 21.5 to 15.6 (p = .05). The maximum phonation time did not change significantly. The postoperative mean Voice Handicap Index score was 21.9. Conclusions Cricotracheal resection can significantly impact the adult female voice. It often lowers the pitch of the speaking voice into the male range and reduces the pitch range of the voice. The change in voice that potentially accompanies this procedure should be discussed with patients in preoperative counseling.
