儿童声带小结发病率不详,据调查小学生患慢性声嘶的,占6％(Seaturia等,1968)至17.4％(Silverman等,1975),而慢性声嘶患声带小结者占38％至78％(Bhme,1969;Shearer,1972;Deal等,1976),由此估计美国学龄儿童患声带小结者,将在百万以上。据查,男为女的2至3倍,独生子女或长子少见。作者与Moore(1956)以超高速电影证实声音是声带前2/3膜部振动所产生,后1/3软骨部在发声中起稳定声带作用。前中1/3交点是振幅最大部位, The prevalence of vocal cord nodules in children is unknown, with chronic hoarseness of primary school pupils accounting for 6% (Seaturia et al., 1968) to 17.4% (Silverman et al., 1975), while chronic hoarseness of vocal nodules accounts for 38% to 78% Bhme, 1969; Shearer, 1972; Deal et al., 1976), which estimates the number of school-age children in the United States suffering from vocal nodules will be more than 1 million. It is found that men and women of 2 to 3 times the only child or eldest son rare. The authors and Moore (1956) demonstrated in ultra-high-speed movies that the sound was generated by the vibration of the first two thirds of the vocal cords, and the latter 1/3 of the cartilaginous parts acted as a stable vocal cords in the vocalization.
