Rhinopharynx endoscopy in the diagnosis of chronic otitis media with effusion in infancy.
Chronic otitis media with effusion is an inflammatory process of the mucosa of the middle ear persisting for more than 3 months, being most frequent in infancy, and is correlated with marked tube obstruction. In infancy, the most frequent cause of this obstruction is adenoid hypertrophy and diagnosis, clinical or radiological, is often not confirmed by rhinopharynx fiberendoscopy. Since, in these cases, treatment is often surgical, it is possible that small patients may be submitted, unnecessarily, to adenoidectomy. In collaboration with the Paediatric Clinic, the present study on an infant outpatient population with nasal respiratory difficulty, associated with chronic otitis media with effusion, was, therefore, aimed at standardizing the endoscopic diagnosis of patients with suspected adenoid hypertrophy. Between October and December 2002, 32 consecutive patients, aged between 4 and 11 years, all oral breathers with OME, were sent to our attention from the Paediatric Clinic. All those patients, with indication for adenoidectomy, have been enrolled in the study and submitted to fiberendoscopic examination of the external ear and nose. Nasal respiration was confirmed with active anterior rhinomanometry. Endoscopic evaluation of the rhinopharynx, aimed at assessing adenoid dimensions and their relationship with the auditory tube, has been expressed in four degrees of increasing severity and adenoidectomy was indicated in those cases, classified, by us, as third and fourth degree. In our experience, endoscopic examination of the rhinopharynx has, however, shown that only 9 children (28.2%) presented an absolute need to undergo adenoidectomy since they were carriers of massive adenoid hypertrophy with tubal obstruction and consequent bilateral glue ear (3rd and 4th degree) while, in all other cases (71.8%), the clinical and radiological findings did not correspond to endoscopic data. Diagnostic accuracy that characterizes rhinopharyngeal fiberendoscopy is, therefore, in our opinion, of fundamental importance to avoid these errors, as far as possible, and in establishing an appropriate therapeutic programme.
