Efficacy of balloon Eustachian tuboplasty plus tympanostomy tube insertion in postirradiation otitis media with effusion

OBJECTIVE

This study aimed to compare the efficacy of balloon Eustachian tuboplasty (BET) plus tympanostomy tube insertion (TTI) and simple TTI for postirradiation otitis media with effusion (OME) in patients with nasopharyngeal carcinoma.

METHOD

This study included 36 patients (51 ears) with OME after the first radiotherapy course for nasopharyngeal carcinoma and categorized them into the BET + TTI and simple TTI groups. Effective rates, pure tone hearing threshold, Eustachian tube function score, and complication incidences were compared.

RESULTS

The effective rates of the BET+TTI and TTI groups were 93.75 % and 75 %, respectively, with no statistically significant difference (P = 0.29). The pure tone hearing threshold examination at 9 months postoperatively revealed significantly lower mean air-pure tone and air-bone gap in both the BET + TTI and TTI groups than preoperatively. Eustachian Tube Dysfunction Questionnaire-7 (ETDQ-7) scores at every postoperative visit were significantly higher than preoperative scores in the two groups (all P < 0.05); ETDQ-7 score reduction in the BET + TTI group at 3, 9, and 12 months postoperatively was significantly higher than that in the TTI group. Otorrhea and recurrence both occurred in the BET+TTI and TTI groups, but the BET+TTI group demonstrated a lower incidence.

CONCLUSION

BET + TTI is an effective treatment method for postirradiation OME.

Diagnostic value of computed tomography in Eustachian tube dysfunction

OBJECTIVE

Investigate radiological findings on temporal bone computed tomography, which are associated with obstructive Eustachian tube dysfunction and determine its diagnostic validity.

METHODS

The present study was conducted as a prospective, cross-sectional case series study in a tertiary referral center. Forty patients with clinically diagnosed unilateral Eustachian tube dysfunction and older than 16 years old underwent pre interventional radiological assessment by temporal bone computed tomography while performing a Valsalva-maneuvre to enhance visualization of Eustachian tube lumen. The Eustachian tubes were assessed for intersite morphological differences, presence of mucus in the lumen or middle ear cleft and secretion retention or mucosal swelling in the adjacent sinuses. Image analyses and radiological statements about the side of pathology were delivered blinded to the clinical diagnoses.

RESULTS

The radiologic detection of mucus/mucosal edema in Eustachian tube or adjacent middle ear cleft structures was associated with the pathological side (t (1, N = 40) = 3.60, p = 0.001 < 0.05). On the contrary, there is no association between radiological findings of sinonasal disease and side of Eustachian tube dysfunction (x² (1, N = 40) = .00, p = 1.00 > 0.05). The diagnostic value of radiologic assessment in Eustachian tube dysfunction has a sensitivity and specificity of 52,5 and 97,5% respectively.

CONCLUSION

The sensitivity of radiologic assessment is rather low, and hence it is inappropriate as a screening tool for Eustachian tube dysfunction in routine clinical practice. In the case of present CT-scans of the temporal bone, the focus should be laid on the detection of mucus in the Eustachian tube or adjacent structures, as a predictor of disease.

Consensus on treatment of obstructive Eustachian tube dysfunction with balloon Eustachian tuboplasty

OBJECTIVE

There is a great variability in diagnosis of obstructive Eustachian tube dysfunction and its treatment by balloon Eustachian tuboplasty (BET). The aim of this paper was to present a consensus on indications, contraindications, methodology, complications and results after BET.

MATERIAL AND METHODS

We obtained a consensus on BET, after a systematic review of the literature on BET from 1966 to November 2018, using MESH terms «Eustachian tube and (dilation or dysfunction)», including a total of 1.943 papers in Spanish, English, German and French. We selected 139 papers with a relevant abstract, including two international consensuses, seven systematic revisions, and two randomised control trials on BET.

RESULTS

The indications for BET are barotrauma, serous otitis media, adhesive otitis, atelectatic middle ear and failure after tympanoplasty, once obstructive Eustachian tube dysfunction is confirmed. BET is more effective in barotrauma and serous otitis media. There are high- evidence reports on BET showing good results that persist long-term, as compared to conservative medical treatment.

CONCLUSIONS

BET is a surgical, minimally invasive treatment that has shown its effectiveness and safety in obstructive Eustachian tube dysfunction in adults and children. It is most effective in barotrauma and serous otitis media.

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.
