Cartilage tympanoplasty combined with eustachian tube balloon dilatation in the treatment of adhesive otitis media

Endoscopic cartilage underlay myringoplasty with or without balloon Eustachian tuboplasty for chronic perforation with Eustachian tube dysfunction

OBJECTIVE

The objective of this study was to compare the outcomes of endoscopic cartilage underlay myringoplasty(CNM) with or without balloon Eustachian tuboplasty (BET) for the treatment of chronic perforation with Eustachian tube dysfunction (ETD).

MATERIALS AND METHODS

A total of 50 ears diagnosed with chronic perforation and ETD were randomly divided into receiving alone CNM and CNM + BET. During the 12 months follow-up, the Eustachian tube score (ETS), Eustachian Tube Dysfunction Questionnaire-7 (ETDQ-7), ET inflammation scale, hearing results and graft success rate of the patients were recorded and analyzed.

RESULTS

The improvement in the ETDQ-7 score was 6.23 ± 2.51 in the CNM + BET group, which was significantly higher than that in the CNM group (4.22 ± 3.85, P < 0.01) at postoperative 3 months, however, no significant between-group difference was found at post-12 months.The graft success rate was 88.0 % in the CNM group and 92.0 % in the CNM + BET group at postoperative 3 months (P > 0.05). Also, no significant difference was found among two groups (84.0 % vs 88.0 %, P > 0.05).The ABG improvement was 13.16 ± 3.19 dB in the CNM + BET group and 9.74 ± 2.56 dB in the CNM group, with a statistically significant between-group difference (P < 0.01)at postoperative 3 months. However, no significant between-group difference was found at postoperative 12 months. During followup process, neither complications nor patulous symptoms were noted. No patients developted atelectasis or otitis media with effusion. However, myringitis was seen in 8 % patients in the CNM group and 12 % patients in the CNM + BET group.

CONCLUSIONS

Although BET combined with endoscopic cartilage myringoplasty had better short-term improvement of hearing and ETDQ-7 scores compared with endoscopic cartilage myringoplasty for the treatment of chronic large perforation with ETD, the long-term outcomes was not satisfactory. Also, BET did not improve the 3-and 12 months graft success rate.

Combined balloon Eustachian tuboplasty/endoscopic sinus surgery for patients with chronic rhinosinusitis and Eustachian tube dysfunction

BACKGROUND

To elucidate the role of balloon Eustachian tuboplasty (BET) in the management of chronic rhinosinusitis with obstructive Eustachian tube dysfunction (ETD), we evaluated the results of endoscopic sinus surgery (ESS) with and without BET in patients with chronic rhinosinusitis with obstructive ETD.

METHODS

This randomized controlled trial conducted in a single-institution tertiary care center setting included 50 patients diagnosed with primary chronic rhinosinusitis and obstructive ETD between July 2018 and June 2022. Twenty-five patients were prospectively enrolled for combined ESS/BET. The control group (25 patients) underwent ESS alone. Outcome measurements of the Sinonasal Outcome Test 22, modified Lund-Kennedy score, Eustachian Tube Dysfunction Questionnaire-7 (ETDQ-7), and serial Eustachian tube function test results were analyzed 3 months postoperatively.

RESULTS

The improvement (12.60 ± 6.50) in the ETDQ-7 score in the BET group was significantly higher than that in the control group (6.60 ± 5.58). The ratio of improvement in the ETDQ-7 score was also significantly higher in the BET than in the control group (92% vs. 68%, p = 0.034). Logistic regression analysis showed that performing BET (odds ratio [OR]: 5.41, 95% confidence interval [CI]: 1.02-28.79, p = 0.048) and a low post-modified Lund-Kennedy score (OR: 0.15, 95% CI: 0.04-0.54, p = 0.004) were significantly associated with ETDQ-7 score improvement.

CONCLUSION

Combined BET/ESS could decrease otologic symptoms and improve Eustachian tube function. BET may be an appropriate adjunctive procedure for treating chronic rhinosinusitis with obstructive ETD.

Balloon dilation of the eustachian tube using endovascular balloon under local anesthesia-a case series and systematic literature review

Objective

To report a novel technique in Balloon Dilation of Eustachian Tube (BDET) using an endovascular balloon (EVB), in a prospective cohort. The results are compared with reported outcomes using standard balloons.

Methods

Demographic information and clinical parameters were collected prospectively fora series of patients with obstructive eustachian tube dysfunction (OETD). Balloon dilation Eustachian tuboplasty was performed under local anesthesia in a tertiary referral center, using the EVB. Systematic literature review was used for comparison, using Medline via "PubMed", "Embase", and "Web of Science".

Results

Eight OETD candidates (12 ears) were enrolled; 5 males and 3 females. Average age was 48 (range -23 to 63) years. The most common presenting symptom was aural fullness (9/12), followed by ear pressure (7/12), hearing loss (5/12) and tinnitus (4/12). Otoscopically, tympanic membrane retraction was evident in 10/12 ears, the majority of which was class II-Sade classification. Pre-operative tympanogram was type B and C in 7 and 5 ears, respectively. All BDETs were performed without complications. Post-operative tympanometry was A in 8/12 ears. Post-operatively, Eustachian Tube Dysfunction Questionnaire-7 results reduced to within normal limits (average score ≤3) in 11/12 ears (p = 0.0014). The systematic literature review included 6 papers (193 patients, 262 ETs) with comparable results, most also with little adverse effects.

Conclusion

BDET using an EVB is a safe and effective option for OETD. It is well tolerated under local anesthesia in properly selected individuals. The reduced procedural cost may be an important factor in certain healthcare jurisdictions.

Evaluation on the possibility of sound conduction independent of tympanic air cavity for severe tympanic adhesion patients by finite element analysis

Background: For patients with severe tympanic adhesion, reconstructing the tympanic air cavity is often challenging, resulting in poor hearing reconstruction outcomes. Therefore, establishing a sound conduction pathway independent of the tympanic air cavity may be a viable method for reconstructing hearing in these patients. Purpose: The objective of this study was to evaluate the feasibility of sound conduction independent of the tympanic air cavity (i.e., replacing the original cavity with a tympanic vibrating material) using finite element analysis. Methods: We established a sound-structure coupling finite element model of the tympanum vibration conduction system, which included the tympanic membrane (TM), ossicular prosthesis, and tympanic vibrating material. This model was used to simulate middle ear vibrations under sound pressure, and we extracted the frequency response curve of the ossicular prosthesis' vibration displacement amplitude to evaluate the sound conduction effect of the middle ear. Next, we adjusted the structural and mechanical parameters of the tympanic vibrating material to analyze its impact on the sound conduction effect of the middle ear. Finally, we compared the frequency response curve of the stapes footplate in normal subjects to evaluate the feasibility of sound conduction independent of the tympanic air cavity. Results: The Shell tympanic vibrating material had a better vibration conduction effect compared to solid or porous tympanic vibrating material. The vibration amplitude decreases with the increasing elastic modulus of the tympanic vibrating material. Implantation of 40 kPa-shell tympanic vibrating material had the lowest hearing loss less than 5 dB, and the hearing loss with 1 MPa-porous tympanic vibrating material was largest and less than 25 dB. Conclusion: Our study suggests that replacing the tympanic air cavity with a tympanic vibrating material is feasible. The establishment of a sound conduction pathway independent of the tympanic air cavity could potentially provide a method for hearing reconstruction in patients with severe tympanic adhesion.

Balloon Eustachian tuboplasty for obstructive Eustachian tube dysfunction: retrospective multicentre cohort study of 248 patients

OBJECTIVE

To present the results after balloon eustachian tuboplasty (BET) in patients with obstructive Eustachian tube dysfunction (OETD) grouped up into: baro-challenge, chronic serous otitis media and adhaesive otitis media.

METHODS

A retrospective study was carried out on patients who underwent BET surgery. As outcome measures, otoscopy, tympanometry, Eustachian tube dysfunction questionnaire-7 (ETDQ-7) and ability to perform the Valsalva manoeuvre were recorded at baseline and at 3, 12 and 24 months after BET. A p value of 0.05 was used to indicate a statistically significant difference for all statistical tests.

RESULTS

Three hundred and nineteen ears (248 patients) were included with a 3-month follow-up, 272 ears had a 12-month follow-up, and 171 ears had 24-month follow-up. Globally, a statistical significance improvement in all groups in all outcome measures was found. According to BET indication, in the baro-challenge group, there was no improvement in otoscopy, but ETDQ-7, Valsalva manoeuvre and tympanogram improved significantly. In the chronic serous otitis media group, otoscopy, ETDQ-7 and Valsalva manoeuvre were significantly improved in all the three timelines, including the avoidance of a new transtympanic tube after the BET in over 80% of cases. In the adhaesive otitis media group, Valsalva manoeuvre improved significantly, ETDQ-7 decreased and tympanogram improved but not significantly. Few mild complications were reported.

CONCLUSIONS

BET is an effective method for the treatment of OETD in all etiologic groups. The greatest benefit was observed in patients with baro-challenge. A long-term follow-up is recommended since the benefit seems to increase over time.

Quality of Life after Surgical Treatment for Chronic Otitis Media: A Systematic Review of the Literature

This systematic review aims to (a) define what instruments are available to measure quality of life (QoL) in patients undergoing tympanoplasty for chronic otitis media (COM) and what is the most commonly selected timing to do so; (b) compare outcomes from different surgical techniques; and (c) describe any reported correlation between subjective and functional results. This review was conducted following the PRISMA statement recommendations. Of the 151 articles screened, 24 were included. Most studies had a prospective design. The mean age at surgery was 44.5 years. A microscopic retroauricular approach was the most common surgical technique. Most articles included both primary and revision surgeries. The most commonly used questionnaire was the Glasgow Benefit Inventory (GBI), followed by the Chronic Ear Survey (CES), the Chronic Otitis Media Outcome Test 15 (COMOT-15) and the Zurich Chronic Middle Ear Inventory (ZCMEI-21). Questionnaires were administered about 12 months after surgery in most studies. Ten studies reported possible associations between hearing results and QoL. QoL assessment after COM surgery variably relies on disease-specific and non-specific questionnaires. Patients are usually evaluated 12 months after surgery, and this appears to be a suitable timing to contrast the possible bias effect of different tympanoplasty techniques associated with different healing times. A comparison between QoL outcomes in different surgical approaches cannot be made, as several influencing factors have not been detailed in the included studies. Few studies have investigated the correlation between subjective and objective outcomes of tympanoplasty for COM so far.

Balloon Eustachian Tuboplasty and Grommet Insertion: A Combined Surgical Treatment for Chronic Suppurative Otitis Media with Eustachian Tube Dysfunction

Objectives. This study aims to evaluate the effectiveness of Balloon Eustachian tuboplasty (BET) and grommet insertion in patients having chronic suppurative otitis media combined with eustachian tube dysfunction (CSOM-ETD). Methods. We evaluated the data of CSOM-ETD patients (n = 96) from January 2019 to January 2021, who were divided into the following groups: 48 cases underwent BET (BET group) and 48 cases underwent BET plus Grommet insertion (BET + Grommet group). The air-bone gap (ABG), Eustachian Tube Dysfunction Questionnaire (ETDQ‐7) score, Eustachian tube inflammation scale, Chronic Otitis Media Outcome Test 15 (COMOT-15), Valsalva maneuver, and patient satisfaction were evaluated after surgery. Results. The postoperative ABG in the BET + Grommet group was better than that in the BET. In addition, the ABG was improved obviously in the BET + Grommet group at 6 and 12 months after the corresponding surgery. Moreover, the Eustachian tube inflammation scale, ETDQ-7, and COMOT-15 scores were reduced after the treatment with the combination of BET and Grommet insertion at 6 and 12 months. The postoperative ETDQ-7 score, Eustachian tube inflammation scale, and COMOT-15 score were lower in the BET + Grommet group than that in the BET group. The percentage of patients who could perform a positive Valsalva maneuver was significantly higher in the BET + Grommet group than that in the BET group at 6 months and 12 months after surgery with increased patient satisfaction. Conclusion. Our results demonstrate that BET plus Grommet insertion showed better treatment efficacy for patients with CSOM-ETD than BET alone via improving the Eustachian tube function hearing outcome and quality of life with less Eustachian tube inflammation.

Clinical Analysis of Ear Congestion after Balloon Eustachian Tuboplasty (BET) with or without Tympanostomy Tube Insertion

Objective

To explore the clinical analysis of ear congestion after balloon Eustachian tuboplasty (BET) with or without tympanostomy tube insertion.

Methods

A total of 35patients (49 affected ears) with ear congestion following BET with or without tympanostomy tube insertion were recruited from the hospitalized patients from January 2015 to December 2017. The score of Eustachian Tube Dysfunction Questionnaire-7 (ETDQ-7) 15, visual analogue scale (VAS), and Valsalva scores were recorded before and after operation, and the influencing factors of prognosis were analyzed. The duration of follow-up was 1-4 years.

Results

All patients showed significantly decreased average preoperative ETDQ-7 score, VAS, and Valsalva score after operation (p < 0.05). The significance of the surgery types, course of disease, severity of tympanic membrane retraction, and tympanogram tracings classification as influencing factors of prognosis did not come up to the statistical standard (p > 0.05).

Conclusion

The patients showed relatively stable postoperative conditions after 3 years, and there were variations in the range of ETDQ-7 scores at 5 years postoperatively. Patients with levels I and II tympanic membrane retraction showed more favorable surgical effects. Surgical interventions are required for patients diagnosed with obstructive Eustachian tube dysfunction (ETD) after three months of conservative treatment without satisfactory results.

Cartilage tympanoplasty in the treatment of adhesive otitis media with and without Eustachian tube balloon dilatation

Purpose

To compare cartilage tympanoplasty (CT) combined with eustachian tube balloon dilatation (ETBD) and cartilage tympanoplasty alone as a surgical treatment modality for adhesive otitis media (AdOM) in terms of graft healing, audiological outcomes, and impact on life style, using Chronic Otitis Media Outcome Test 15 (COMOT-15).

Methods

50 patients with AdOM were randomly classified into 2 groups: 25 patients for cartilage tympanoplasty only (CT group) and 25 patients for cartilage tympanoplasty combined with eustachian tube balloon dilatation (CT + ETBD group). Clinical outcomes in both groups were compared at 3 and 6 months of follow up.

Results

There was no significant difference in graft healing between the two groups. Postoperative COMOT-15 scores significantly decreased in both groups with a significant difference between the groups with regard to the decrease in COMOT-15 scores at 3 and 6 months of follow-up (P < 0.05). Hearing improvement was achieved, as the mean preoperative ABG was 26.5 ± 5.4 and 27.1 ± 4.6 dB, and the mean postoperative ABG at 6 months was 19.4 ± 4.4 and 14.6 ± 3.9 dB in the CT and the CT + ETBD groups, respectively. The difference in the magnitude of ABG reduction in the two groups was significant at 3 and 6 months of postoperative follow-up (P < 0.05) in favour of the CT + ETBD group.

Conclusion

ETBD can increase the success rate of cartilage tympanoplasty in patients with AdOM by enhancing the audiological outcome and quality of life.

Radiological dimensions of the Eustachian tube in patients with adhesive otitis media

OBJECTIVE

This study aimed to analyse the computed tomography parameters for effective ventilation in patients with adhesive otitis media.

METHODS

Twenty-six patients with unilateral adhesive otitis media were included in the study. The patients' temporal bone computed tomography images were retrospectively reviewed. Eustachian tube length and diameter were measured. Mastoid pneumatisation and middle-ear size were evaluated by measuring petroclival and Eustachian tube-tympanic cavity ventilation angles.

RESULTS

The average Eustachian tube length was 38.4 mm and 38.9 mm in adhesive otitis media and healthy ears, respectively. The Eustachian tube diameter of the adhesive otitis media ears (1.47 mm) was significantly narrower than that of the healthy ears (1.83 mm). There were no significant differences in the angles between adhesive otitis media and healthy ears.

CONCLUSION

A narrow Eustachian tube diameter was associated with developing adhesive otitis media. Measuring Eustachian tube diameter is simple and can be routinely performed when examining temporal bone computed tomography images for Eustachian tube function evaluation.

The Role of Cartilage-perichondrium Tympanoplasty in the Treatment of Tympanic Membrane Retractions: Systematic Review of the Literature

Introduction  Tympanic retraction is a condition characterized by the displacement of the tympanic membrane toward the structures of the middle ear. Clinically, tympanic retractions can lead to hearing loss, ear discharge and/or ear pain. In most of the cases, however, tympanic retractions are asymptomatic and are found accidentally during an ear, nose, and throat (ENT) examination. This condition has created numerous debates regarding the optimal choice of treatment, especially in the asymptomatic forms. The main controversy is regarding the relationship between retraction and the development of cholesteatoma, which would justify a surgical intervention performed for preventive purposes.

Objectives  To study the effectiveness of cartilage tympanoplasty in the management of tympanic membrane retractions by analyzing the results of the studies conducted on the use of cartilage as a reconstruction material.

Data Synthesis  A literature review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses group (PRISMA). Study selection, data extraction, and quality assessment were conducted independently by two reviewers. Our initial literature search yielded 2,258 references. Applying the PRISMA flow chart, 1,415 duplicates were excluded, and the remaining 843 abstracts were examined. Afterwards, 794 articles were excluded based on the research protocol criteria. Only 8 papers were included in the review by applying the inclusion and exclusion criteria.

Conclusions  Despite the limitations of the studies taken into consideration, we can conclude that cartilage tympanoplasty may successfully rehabilitate the atelectatic ear especially in the more advanced stages of retraction, unlike the conservative strategies.

Balloon dilation eustachian tuboplasty for dilatory dysfunction: Safety and efficacy analysis in an Australian cohort

BACKGROUND

Eustachian tube dysfunction (ETD) is a common clinical condition encountered by otolaryngologists. The severity and duration of symptoms range from the mild and transient to the chronic and severe along with secondary pathologies. Balloon dilation eustachian tuboplasty (BDET) as a treatment, was first described in 2010 and has been studied extensively. This study evaluates the efficacy and safety of BDET in an Australian cohort.

METHODS

Retrospective chart review on all patients who underwent BDET from September 2016 to March 2020 was performed. The Eustachian Tube Dysfunction Patient Questionnaire (ETDQ-7) was chosen as the primary outcome measure. Secondary outcome measures included subjective global assessment of presenting symptoms, ability to perform Valsalva maneuver and tympanometry. Any complications related to the procedures were reported.

RESULTS

One hundred and nineteen eustachian tube operations were included in this study. The patient cohort showed statistically significant improvement of mean EDTQ-7 score from 0.7 to 2.9. Improvement in EDTQ-7 was achieved in 83.9% of the cases. All patients in the baro-challenge-induced subgroup achieved improvement in ETDQ-7 score. Complete resolution of symptoms with an ETDQ <2.1 was achieved in 37.1% of the cohort. There were no adverse safety events associated with the procedures.

CONCLUSION

BDET resulted in improvement of the EDTQ-7 score in most of patients in this Australian cohort with no reported complications. BDET was most successful in baro-challenge-induced subgroup with universal improvement. Lower success rates were seen in patients with secondary pathology from their ETD.

Endoscopic full-thickness cartilage-perichondrium double graft myringoplasty in adhesive perforation: retrospective case series

BACKGROUND

The adhesive perforation could be the sequela of adhesive otitis media, that partial tympanic membrane remnant is bound completely to the medial wall of the middle ear by fibrous adhesions. However, few studies have reported on the repairing of adhesive perforation.

OBJECTIVES

To evaluate the long-term outcome of endoscopic full-thickness cartilage-perichondrium double graft myringoplasty for adhesive perforation.

MATERIALS AND METHODS

In total, 26 patients with unilateral adhesive perforation associated with chronic otitis media who underwent full-thickness cartilage-perichondrium double graft myringoplasty were included. Outcomes were evaluated in terms of the hearing gain and graft success rate at 12 and 24 months.

RESULTS

The graft success rate was 96.15% (25/26) at 12 months and 88.46% (23/26) at 24 months. The neovascularization and epithelium covering the lateral surface of the cartilage graft were seen at preoperative 4 weeks, the superficial cartilage graft got complete epithelialization within 4-6 months. CT revealed the well-pneumatized middle ear and mastoid cells at postoperative 24th months in all the patients, no middle ear cholesteatoma formation and keratin pearls were found during the period of follow up.

CONCLUSIONS

Endoscopic full-thickness cartilage-perichondrium double graft myringoplasty without the tympanomeatal flap elevation is a feasible method for repairing adhesive perforations, with a higher graft success rate and satisfactory hearing results.

Panel 5: Impact of otitis media on quality of life and development

OBJECTIVE

To summarize recent advances in knowledge on otitis media (OM) and quality of life (QoL) and development by synthesizing relevant research in this field published between June 1., 2015 until June 1., 2019.

DATA SOURCES

Systematic searches of PubMed, Embase and the Cochrane Library using predefined database-specific syntaxes.

REVIEW METHODS

Articles selected were randomized controlled trials and observational studies with an adequate control group estimating treatment effects of OM including acute OM (AOM), recurrent AOM (RAOM), OM with effusion (OME), chronic OM (COM) and chronic suppurative OM (CSOM). Items included were Health Status, Health Status Indicators, Quality of Life, Functional Status, Specific Learning Disorder, Developmental Disabilities, Language Development Disorders, and Problem Behavior.

RESULTS

The electronic database searches yielded a total of 699 records. After screening titles and abstracts, we identified 34 potentially eligible articles. Of these, 18 were excluded. This left 15 articles suitable for inclusion.

CONCLUSIONS

Although evidence is accumulating that OM may significantly impair children's QoL and development as well as caregiver's QoL, studies on this topic are relatively scarce and vary substantially in terms of methodological quality and outcome measurement instruments (OMI) used. In this review, studies have used 10 different OMIs capturing a wide range of OM symptoms as well as generic and disease-specific QoL outcomes. OM was associated with negative effects on auditory processing, language and speech development, school readiness, social competence, psychosocial wellbeing, and sleep. We found only four relevant randomized controlled trials, which mostly failed to demonstrate superiority of interventions in terms of QoL improvement and reports on reversibility are lacking. This underpins the urgent need for high quality studies in this field using validated and uniform OMIs. To facilitate interpretation and harmonization of study findings, we suggest and support the development of a core outcome set for the various OM entities that should include the most reliable and meaningful QoL and developmental OMIs.
