本研究的目的是确定由于鼓膜置管引起的鼓膜穿孔所造成的听力损害的程度。在1977年至1978年期间，我们治疗了146名患有双侧分泌性中耳炎的儿童，采用腺样体切除术，右侧插入通气管，左侧鼓膜切开术。术后2 - 3年和6 - 7年再次复查儿童，并在250、1000和4000 Hz下评估听力。鼓室压在59%的儿童中表现出对侧的耳朵相比，13%。鼓室积液耳听力稍差于无鼓室积液耳，但差异无显著性。鼓膜穿孔引起的听力损害小于0.5 dB，这是无关紧要的，不能作为反对使用通气管的论据。然而，需要更长观察期的进一步研究。
The aim of the present study was to determine the degree of hearing impairment caused by tympanosclerosis of the eardrum as a result of grommet insertion. During the period 1977 to 1978 we treated 146 children who had bilateral secretory otitis with adenoidectomy, insertion of a ventilation tube on the right side, and myringotomy on the left. The children were reexamined 2 to 3 years and again 6 to 7 years postoperatively, and hearing was evaluated at 250, 1000, and 4000 Hz. Tympanosclerosis was demonstrated in 59% of the children on the side with grommet insertion compared with 13% in the contralateral ear. Hearing was slightly inferior in ears with tympanosclerosis compared with ears without tympanosclerosis, but the difference was small and nonsignificant. The hearing impairment caused by tympanosclerosis was less than 0.5 dB, which is inconsequential and cannot serve as an argument against the use of ventilation tubes. However, further studies with longer observation periods are warranted.
