Our electronic laryngoscopic vocal cord surgery has more than 10,000 patients each year, the following issues should be concerned after surgery in order to help voice recovery: 1, the time of vocal abstinence: according to the traditional custom, the patient is asked to abstain from voice for 1 to 2 weeks after surgery, and some people propose to abstain from voice for half a month. However, scholars found in practice, the time of the prohibition is too long, and then let the patient vocalize, often the patient can only make a whispering sound, and some even lose their voice, and then correct the vocalization is quite difficult. The reason for this may be due to the prolonged vocal abstinence period, resulting in the inhibition of brain function, is an “artificial factor” caused by the psychological disorder of vocalization. Therefore, it is now advocated that except for cases with extensive vocal fold surgery trauma, the regular postoperative vocal prescription is “three, four, seven”, that is, three days postoperative vocal abstinence, four days to start gradually practicing voice, seven days to start normal vocalization, two weeks later can be engaged in normal work, including full-time voice workers such as actors, announcers, teachers, etc. 2, vocal tone: when you start to let patients vocalize, doctors are always used to let patients “whisper” or “low tone”, but practice has proved that when the tone is too low, it requires additional muscle tension to maintain the necessary vocal cord length and volume to adjust the tone, so This will increase the burden on the vocal cords and is not conducive to the healing and loosening of the wound. Based on the above principle, when starting to vocalize, patients are required to maintain normal tone and intensity, but the vocal time should not be too long, and should be gradual. 3, vocal correction: after surgery, about 20% of patients still have vocal disorders, manifested as persistent mute, dull tone, some actors can not go up the tone, some teachers feel vocal fatigue when lecturing, etc.. The laryngological examination shows that the primary lesion has been completely removed, the vocal folds have returned to normal form, and the vocal folds are well closed or slightly cleft. In the face of the patient’s desire doctors will take a variety of treatment measures, such as endless vocal rest, laryngeal seal, nebulization, massage, massage and Chinese medicine, but with little success, the doctor has felt powerless, helpless, the only correct choice is to carry out vocal correction.
