1, grumpy type: after surgery must be calm, and then can not be arbitrary, capricious temper, otherwise the polyp will definitely recur. 2, too much speech type: after a long time speech, or too much speech, feel throat fatigue, to appropriate sound rest; after drinking, menstruation and cold, must be sound rest; otherwise polyps will definitely recur. 3, tired type: usually do not lose temper, speech is also the same as usual, and not much. The main reason is that after working too hard or too strenuous (working overtime or staying up late), the body is in poor condition and the vocal cords are poorly tolerated, so they are easily congested with fatigue and cause hoarseness. Don’t stay up too much after surgery, don’t overwork, and rest well so as not to relapse easily. 4, subhealth type: white-collar workers (office work), mothers with children, teachers, menopausal women, etc., usually do not speak too much, work is not strenuous, but often feel fatigue, the reason is not good rest, or lack of exercise. The same as the exertion type, the physical state is very poor, the vocal cords are poorly tolerated, easily fatigued and congested, causing hoarseness. It is necessary to rest well, exercise properly and overcome subhealth. With a strong physique and physical fitness, in order to speak more without hoarseness. 5, comprehensive type: impatient temper, too much speech, overwork, long-term excessive smoking and alcohol, etc. Only by finding the cause of long vocal cord polyps and paying high attention to it (etiological treatment) can we prevent recurrence after surgery.
