Preparation and placement of cartilage island graft in tympanoplasty

To Study the Outcome of Cartilage Tympanoplasty Type I in Patients with Medium and Large Perforations Using 0.5 mm Sliced Conchal Cartilage Reinforced with Temporalis Fascia Grafts with 5 Years Follow-up

Aims

To study the outcome of cartilage tympanoplasty type I in patients with medium and large perforations using 0.5 mm sliced conchal cartilage reinforced with temporalis fascia grafts with 5 years follow-up.

Study Design

Retrospective clinical study.

Patients and Method

120 patients with dry tympanic membrane perforation medium and large size and intact ossicular chain, and with no history of previous ear surgery were selected. An underlay type one tympanoplasty, using 0.5 mm sliced conchal cartilage reinforced with temporalis fascia, was performed during 2018-19. A successful anatomical outcome was considered to comprise full, intact healing of the graft without perforation these patients were evaluated for at least 5 years post-operatively till 2023.

Results

In this study graft uptake rate was 95.33% for medium size and 93.66% for large perforations at 3 months and after 5 years of follow-up 92.77% medium size and large size perforations were 89.67.66% (P < 0.001). Residual perforations were there in about 7.29% in medium and 10.33% in large size perfrations.

Conclusion

Sliced conchal cartilage reinforced with temporalis fascia is a reliable technique for tympanoplasty, with improved graft uptake results in medium and large perforations in the long-term, also the residual perforations is significantly lower.

Tympanoplasty in the Setting of Complex Middle Ear Pathology: A Systematic Review

OBJECTIVE

To assess the prognostic factors for anatomic and hearing success after tympanoplasty in the setting of complex middle ear pathology.

METHODS

A systematic review was performed in January 2022. English-language articles describing outcome data for tympanoplasty repair variables including underlying pathology, perforation location, smoking status, graft technique, reconstruction material, anatomic success, and hearing success were extracted. Articles were included when tympanosclerosis, retraction pockets, adhesions, cholesteatoma, chronic suppurative otitis media, anterior perforations, and smoking were included. Underlying pathology, perforation location, smoking status, graft technique, reconstruction material, anatomic success, and hearing success were extracted. Any factors analyzed as potential indicators of success were sought out.

RESULTS

Data sources included PubMed, OVID, Cochrane, Web of Science, Scopus, and manual search of bibliographies. Ninety-three articles met final criteria, which accounted for 6685 patients. Fifty articles presented data on both anatomic and hearing outcomes, 32 articles presented data on anatomic outcomes only, and 11 articles presented data on hearing outcomes only. This systematic review found that adhesions and tympanosclerosis were prognostic factors for poorer hearing. Additionally, smoking and tympanosclerosis may be predictive of anatomic failure; however, the significance of this finding was mixed in included studies. This analysis is significantly limited by both the heterogeneity within the patients and the lack of controls.

CONCLUSION

Adhesions and tympanosclerosis were prognostic factors for poorer hearing. Clearly documented methods and outcomes for the included pathologies could lead to more definitive conclusions regarding prognostic factors for success.

Cartilaginous Myringoplasty: Anatomical and Functional Results

INTRODUCTION

 Myringoplasty remains a topical subject. Our study aims at analyzing the anatomical and functional results of cartilaginous myringoplasty, and also determining the main factors that could influence its results.

MATERIALS AND METHODS

 A retrospective study of 51 cases of tympanic perforations operated at the ENT department of the Hassan II University Hospital of Fez between January 2018 and November 2021. Only the patients with exclusive cartilage myringoplasty were included. The anatomical and functional results of cartilage myringoplasty were evaluated and analyzed according to several variables. The statistical analysis was performed using SPSS Statistics software.

RESULTS

 The average age of our patients was 35, with a sex ratio of 2.45. The perforation was anterior in 58%, posterior in 12%, and central in 30% of the cases. The average pre-operative audiometric air bone gap (ABG) was 29.3 dB. The most commonly used graft was the conchal cartilage in 89% of cases. A complete cicatrization has been noticed in 92%, and at six months after surgery, a complete closure of the ABG has been observed in 43% of cases, a significant hearing improvement with an ABG between 11 and 20 dB in 24%, a hearing recovery with an ABG between 21 and 30 dB in 21%, and an ABG > 30 dB in 12% of the cases. A statically significant relationship (p<0.05) has been found between the functional or anatomical failure of the myringoplasty; the different predictive factors were: the young age (less than 16 years), the inflammatory state of the tympanic cavity, the anterior location, and large size of the perforation.

CONCLUSION

Cartilaginous myringoplasty provides good anatomical and auditory results. The pre-operative predictive factors, such as age, complete and sufficient drying of the ear, the size and location of the perforation, and the size of the used cartilage, should all be considered for a better anatomical and functional outcome.

Healthcare consumption among subjects with otitis media undergoing middle ear surgery-analysis of cost drivers

PURPOSE

To map healthcare utilized by subjects with chronic otitis media, with or without cholesteatoma and perform a cost analysis to determine key drivers of healthcare expenditure.

METHODS

A registry study of 656 adult subjects with chronic otitis media that underwent a middle ear surgery between 2014 and 2018. Healthcare contacts related to all publicly funded specialist ENT care, audiological care and primary care for a disease of the ear and mastoid process were extracted. The data are extracted from the Swedish National Patient Registry on subjects that reside in western Sweden.

RESULTS

Subjects made 13,782 healthcare contacts at a total cost 61.1 million SEK (6.0 million EUR) between 2014 and 2018. The mean cost per subject was 93,075 SEK (9071 EUR) and ranged between 3971 SEK (387 EUR) and 468,711 SEK (45,683 EUR) per individual. In the most expensive quartile of subjects, mean cost was 192,353 SEK (18,747 EUR) over the 5-year period. These subjects made 3227 ENT contacts (roughly four each year) and 60% of total costs were associated with in-patient ENT care.

CONCLUSION

Patients with chronic otitis media are associated with high ENT resource utilization that does not diminish after surgical intervention and the disease places a long-term burden on healthcare systems. Significant costs are attributed to revision surgeries, indicating that these patients could be managed more effectively. In many such cases, reoperation cannot be avoided, especially due to recurrence of cholesteatoma. However, in some patients, when the indication for subsequent surgery is only hearing improvement, alternative options, such as hearing aids or implants, should also be considered. This is especially true in difficult cases, where revision ossiculoplasty is likely.

Revision of cartilage tympanoplasty with endoscopic butterfly inlay myringoplasty

PURPOSE

While the use of cartilage graft for revision tympanoplasty is quite common, the data on the revision of cartilage tympanoplasty are limited. Our study aims to present the results of our patients who underwent endoscopic butterfly inlay myringoplasty for the revision of cartilage tympanoplasty.

METHODS

Demographic data, ear sides, perforation locations, graft success rates and hearing results of the patients who underwent endoscopic butterfly inlay myringoplasty for revision of cartilage tympanoplasty between Sep 2017 and Jan 2020 were evaluated.

RESULTS

A total of 17 patients with 7 (41%) females and 10 (59%) males were included in our study. Eight of the ears (47%) were right and nine (53%) were left. Perforation locations included ten (59%) anterior, six (35%) inferior, and one (6%) posterior. The graft success rate of our study was 100%. No changes were observed in post-operative air conduction, bone conduction and air-bone gap values compared to the pre-operative period (p > 0.05).

CONCLUSIONS

Endoscopic butterfly inlay myringoplasty for the revision of cartilage tympanoplasty is considered to be a safe surgical technique with satisfactory anatomical and hearing results.

Over-under cartilage tympanoplasty: technique, results and a call for improved reporting

OBJECTIVE

This study aimed to describe the microscopic over-under cartilage tympanoplasty technique, provide hearing results and detail clinically significant complications.

METHOD

This was a retrospective case series chart review study of over-under cartilage tympanoplasty procedures performed by the senior author between January 2015 and January 2019 at three tertiary care centres. Cases were excluded for previous or intra-operative cholesteatoma, if a mastoidectomy was performed during the procedure or if ossiculoplasty was performed. Hearing results and complications were obtained.

RESULTS

Sixty-eight tympanoplasty procedures met the inclusion criteria. The median age was 13 years (range, 3-71 years). The mean improvement in pure tone average was 6 dB (95 per cent confidence interval 4-9 dB; p < 0.0001). The overall perforation closure rate was 97 per cent (n = 66). Revision surgery was recommended for a total of 6 cases (9 per cent) including 2 post-operative perforations, 1 case of middle-ear cholesteatoma and 3 cases of external auditory canal scarring.

CONCLUSION

Over-under cartilage tympanoplasty is effective at improving clinically meaningful hearing with a low rate of post-operative complications.

Comparative Analysis of Fascia Lata and Cartilage Graft in Revision Type 1 Tympanoplasty

To evaluate graft epithelialization and hearing outcome in type 1 revision tympanoplasty using fascia lata and cartilage as graft material. In this study 33 revision cases of dry central perforations were divided into two groups, group 1 (n = 21) in which cartilage was used as a graft and group 2 (n = 12) in which fascia lata was used. Group 1 patients were divided according to the technique used as group 1a (n = 16) cartilage perichondrium composite island graft and group 1b (n = 5) cartilage butterfly inlay graft. Patients were followed up for at least 12 months postoperatively, mean 15.63 (± 4.21) months. Outcome among the two groups were measured and compared in terms of graft epithelization and hearing improvement measured as the difference between pre and post operative mean air bone gap (ABG) at 1 year. The graft epithelialization of group 1 was 85.72% (87.5% group 1a/80% group 1b) and of group 2, 83.34%. Statistically no significant difference was found in the success rate between the two groups (p = 0.6). No significant difference was found in the hearing outcome as well (p = 0.44). The overall hearing improvement was significant in both groups (p = < 0.001) including the sub groups 1a and 1b separately. 21 out of 33 patients (63.63%) operated had a mean postoperative ABG of 20 db or less. The results of cartilage and fascia lata as graft are comparable in terms of graft epithelialization and hearing outcome in revision tympanoplasty.
