Background/Aim. Secretory otitis media (SOM) is a chronic, nonpurulent inflammation of the middle ear, characterized by a long-term presence of liquids of different density in the middle ear for at least three consecutive months, different degrees of hearing loss and the absence of perforation of the eardrum. The aim of this study was to estimate the early postoperative complications after insertion of tympanostomy tube (TT) in children with secretory otitis media (SOM) in an 18-month period after TT insertion. Methods. This retrospective study included children with SOM (n = 478), aged from 2.5 to 16 years, operated from 2000 to 2009. During these ten years 365 children had TT in both ears, 131 children had TT in one ear and 55 children were operated two or more times. Totally 843 ears were operated on. Date were obtained by regular fallow up in Out-patient clinic concerning symptoms reported by children and parents, otomicroscopy findings and hearing measurements (audiometry and tympanometry). Results. Transient otorrhea was the most common early postoperative complication (16.5%), then obstruction (9.5%), premature extrusion of TT (3.9%), chronic otorrhea (3.1%), granulation tissue (1.1%) and medial displacement (0.5%). According to our experience gold and silicone TT were shown less successful than others. The incidence of premature extrusion of TT was significantly higher with gold TT, comparing to others (6/33, 18%; p < 0.001). We also found significantly more frequent medial displacement with silicone TT than with other ones (2/4, 50%; p < 0.001). Conclusion. There are many early postoperative complications of TT insertion, but they depend on the meticulous surgery techniques, regular postoperative examinations and the type of TT. The type of TT should be determined according to own experience.
