212 of 242 patients (88%) treated for chronic secretory otitis media in 1972 were re-examined 5 years later. A total of 668 otological procedures has been performed, 99 patients being treated only once, while one patient received 12 procedures. The pure tone threshold was 20 dB or less in 88% of the ears in 1977, whilst only 57% had a type A tympanogram. Normal otoscopy was found in 40.5% of the ears, persisting secretory otitis in 11%, atelectasis in 2.8% and chronic suppurative otitis in 2.6%; the remaining 42.9% showed varying degrees of scarring and myringosclerosis.
