    Author: Daudia A, Yelavich S, Dawes PJ.
    Journal: J Laryngol Otol; 2010 Sep; 124(9):945-9. PubMed ID: 20403228.
    Abstract:
    OBJECTIVE: Long-term tympanostomy tubes are associated with a significant rate of complications, particularly persistent perforation. We describe the outcomes of 57 subannular ventilation tube insertions in 45 consecutive patients. DESIGN: Retrospective case series. SUBJECTS: We studied 45 consecutive patients with chronic otitis media with effusion and hearing loss (n = 54 cases), associated with adhesive otitis media (n = 7), tympanic membrane retraction (n = 17) and tympanic membrane perforation (n = 3). The mean follow up was 48 months (range, nine to 95 months). RESULTS: The mean duration of ventilation for tubes still in situ was 22 months (range, one to 76 months; n = 29), and for tubes which extruded or were removed 23 months (range, one to 85 months; n = 28). The mean improvement in air-bone gap was 14 dB (range, -14 to 35 dB). Complications included blockage (16 per cent), perforation after extrusion (9 per cent), granulation (5 per cent) and infection (4 per cent). CONCLUSION: Subannular ventilation tubes provide an effective option for management of intractable middle-ear effusion and eustachian tube dysfunction.
