Abstract
Large-bore myringotomy tubes are usually reserved for the treatment of refractory middle ear effusion. Theoretically, they have an extended intubation time and a higher complication rate. There is, however, scant support of this in the literature. The duration of intubation, efficacy, and complication rates of the large-bore Paparella type II tube were compared with Paparella type I, Shepard, and Armstrong tubes. The study included 242 patients with 600 intubations. In addition, a subpopulation of patients receiving their initial intubation during this study was reviewed. Findings were similar for both groups. Paparella type II tubes had a prolonged period of intubation and a decreased reintubation rate when compared with the smaller bore tubes. Larger bore tubes had an increased complication rate when compared with the smaller bore tubes. Complications included occasional or frequent otorrhea and an increased rate of permanent perforation of the tympanic membrane. There was no instance of cholesteatoma formation secondary to intubation. Guidelines are presented for the use of the Paparella type II tube.
