To the Editor: We thank Dr. Finerty for his comments. We have reviewed the 29 study cards of those patients who were termed "treatment failures," in none of whom was myringotomy performed because of the continuation of bulging tympanic membranes. Of those who had subsequent audiograms, one patient had a hearing loss of 15 to 20 decibels at a frequency of 4,000 and another had losses of 15 and 20 decibel in his left and right ear, respectively. The remaining children had either normal audiograms or were too young to be tested.
The 5-year-old boy who had a 30 decibel hearing loss had originally presented with a draining left ear; two weeks later, the tympanic membrane appeared somewhat dull. At this time, his hearing was thought to be normal clinically, but five days later and again one month later a hearing deficit was present, though inconsistently, as shown by audiogram.
