A comparison of audiometric performance and complications of T tubes and Shepard grommets.
Since T tubes were introduced in 1972 their use in cases of chronic Eustachian-tubal insufficiency has been reported on several occasions, (Goode, 1973, 1983; Rothera and Grant, 1985). T tubes remain in-situ for longer than grommets, and they are frequently used in cases where multiple grommet insertions have failed to provide adequate middle ear ventilation. They have also been used when prolonged Eustachian-tubal insufficiency is anticipated, for instance in children with cleft palate. Shepard grommets continue to be the most commonly used type of ventilating tube for short-term use and a significant proportion of children with glue ear require repeated insertions. In an attempt to reduce the need for repeated myringotomy, and also to reduce the need for adenoidectomy in children with glue ear, it has been the recent practice of one Consultant (K.S.M.) to use T tubes routinely in all cases of glue ear. This study analyses the audiometric performance and complications of 32 children (60 ears) who underwent myringotomy and insertion of T tubes for glue ear. In all cases no previous treatment for glue ear had been undertaken. The results are compared with those of a control group who underwent myringotomy with insertion of Shepard grommets and adenoidectomy as a first-line treatment.
