Effects of combination of balloon Eustachian tuboplasty with methylprednisolone irrigation on treatment of chronic otitis media with effusion in adults.

PURPOSE: Adult chronic otitis media with effusion (COME) is characterized by Eustachian tube dysfunction and mucosal inflammation, which management has long been a challenge because of high recurrence. This study was to investigate the pathological changes of Eustachian tube mucosa and optimized treatment. MATERIALS AND METHODS: Retrospective study of four groups: I: tympanic paracentesis, II: balloon Eustachian tuboplasty (BET), III: BET plus tympanic paracentesis, IV: BET and tympanic paracentesis with methylprednisolone irrigation. Biopsy of Eustachian tube mucosa was obtained preoperative and 1 month post. Recurrence ratio and Eustachian tube scores (ETS) were used to evaluate the effect of treatments. RESULTS: All patients showed narrowed with edematous and thickened Eustachian tube mucosa. At 1 month post-treatment, BET with methylprednisolone irrigation significantly decreased intraepithelial inflammation and restored the quality of epithelium and cilia. For group II to IV, The recurrence rate was significantly lower in group IV compared with the other two, but only significantly lower in group IV VS group II at 3 months and 6 months, no significant difference at 12 months. The recurrence rate was significantly higher in group I during follow-up. The ETS were improved in group II, III and IV after treatment. At 1 month and 3 months posttreatment, group IV had significant higher ETS compared with other groups (P < 0.05). There was no serious complications occurred. CONCLUSION: Methylprednisolone irrigation could help to recover mucosal function. BET and tympanic paracentesis with methylprednisolone irrigation could be regarded as a good choice for COME in adults, which has less recurrence rate and prompt recovery of ET function.

Round Window Niche Drilling with Intratympanic Steroid Is a Salvage Therapy of Sudden Hearing Loss.

OBJECTIVE: To explore the effectiveness and safety of round window niche drilling combined with intratympanic methylprednisolone injection for the salvage treatment of sudden sensorineural hearing loss (SSNHL) and its associated tinnitus after failed primary treatment. METHOD: SSNHL patients who showed a less than 10-dB improvement of pure-tone average after receiving standard systemic treatment and intratympanic steroid injection were enrolled. All included patients were randomly divided into two groups (control and study). Patients in the study group received round window niche drilling combined with daily intratympanic methylprednisolone for 7 times; the control group received only daily intratympanic methylprednisolone for 7 times. One month after treatment, the improvements of PTA, speech discrimination score (SDS), tinnitus and the incidence of adverse events were analyzed. RESULTS: 20 patients (10 for each group) were included in this study. The baseline between two groups showed no statistical significance. Patients in the study group experienced an average hearing improvement of 20.38 dB, SDS 19.3 compared with 2.1 dB and SDS 2.0 in the control group. None (0%) in the control group and 4 patients (40%) showed marked recovery, 5 patients (50%) showed slight improvement of hearing in the study group after 1 month. All patients in the study group showed significant recovery of tinnitus. Both tinnitus handicap inventory and a symptom visual analogue scale between two groups revealed statistical differences (p < 0.001, p = 0.002, respectively). None in the control and study groups experienced vertigo, infection and facial paralysis. CONCLUSION: Round window niche drilling increases the contact area and time of methylprednisolone. It is an effective and safe salvage therapy of idiopathic SSNHL and its induced tinnitus.
