Endoscopic Perichondrium-Cartilage Myringoplasty With Preserving of Anterior Margins and Tuck Grafts for Repairing Anterior Perforation With 3 year Followup

OBJECTIVE

The objective of this study was to evaluate the graft outcomes of endoscopic perichondrium-cartilage myringoplasty with preserving of anterior margins for repairing anterior perforation with 3 year followup.

STUDY DESIGN

Prospective case series.

SETTING

Tertiary university hospital.

MATERIALS AND METHODS

We performed a prospective study in 47 patients with anterior perforation who underwent perichondrium-cartilage myringoplasty with preserving of anterior margins and tuck grafts. The operation time, graft success rate, hearing outcome, and complications were evaluated at 6 months and 3 years after surgery.

RESULTS

A total of 47 ears with anterior marginal perforation were included in the study. The perforation size was subtotal in 2 (4.3%) eras, large in 11 (23.4%) ears, medium in 27 (57.4%) ears, and small in 7 (14.9%). The mean operation time was 41.2 ± 5.4 minutes. All patients completed 6 months of follow-up. Residual perforation was observed in 2 patients with medium perforations, the graft success rate was 95.7% (45/47). The mean preoperative and postoperative AC PTAs were 38.1 ± 7.3 dB and 25.4 ± 4.6 dB (P < .05), while the mean preoperative and postoperative BC PTAs were 9.0 ± 4.6 dB and 9.6 ± 1.9 dB (P = .672). The functional success was 91.5% (43/47). None of the patients reported sensorineural hearing loss, altered taste, facial nerve palsy, vertigo, or tinnitus during the follow-up period. In addition, 34 (72.3%) patients completed 3 years followup and performed temporal bone CT examination, the mean followup time was 39.1 ± 2.7 months, CT revealed the well pneumatization of mastoids and middle ear.

CONCLUSIONS

Endoscopic perichondrium-cartilage myringoplasty with preserving of anterior margins and tuck grafts is a safe, suitable, and reliable method for repair of anterior perforation with few risk of anterior blunting and lateralization.

Comparison of perichondrium-cartilage double and single underlay myringoplasty for subtotal perforations: a randomized controlled trial

OBJECTIVE

The objective of this study was to compare graft outcome, operation time and surgical complications of the double and single perichondrium-cartilage underlay techniques for repairing subtotal tympanic membrane (TM) perforations.

MATERIALS AND METHODS

Patients with unilateral subtotal perforations undergoing myringoplasty were prospectively randomized to undergo DPCN or SPCN. The operation time, graft success rate, audiometric outcomes, and complications were compared between these groups.

RESULTS

In total, 53 patients with unilateral subtotal perforations were included (DPCN group, 27; SPCN group, 26).All patients completed 6 months of follow-up. The mean operation time was 41.2 ± 1.8 min in the DPCN group and 37.2 ± 5.4 min in the SPCN group, the difference was not significant (p = 0.613).The graft success rates were 96.3% (26/27) in the DPCN group and 73.1% (19/26) in the SPCN group, the difference was significant (p = 0.048). During the period of follow-up, residual perforation was found at postoperative in one (3.7%) in the DPCN group, while cartilage graft slipped (graft lateralization) in 2 (7.7%) and residual perforation in 5 (19.2%) were found in the SPCN group, the difference of residual perforation was not significant among two group (p = 0.177).In addition, no significant between-group differences were observed pre- (p = 0.741) or post- (p = 0.687) operative ABG values or mean ABG gain (p = 0.659) (Table 2).The functional success rates (postoperative ABG ≤ 20 dB) were 85.2% (23/27) in the DPCN group and 73.1% (19/26) in the SPCN group (p = 0.454).

CONCLUSION

Although similar functional result and operation time can be obtained with double perichondrium-cartilage underlay technique compared to the single perichondrium-cartilage underlay technique for endoscopic closure of subtotal perforations, double unerlay technique offers better anatomical result with minimum complications.

Otologic use of porcine small intestinal submucosal graft (biodesign): A MAUDE database review

OBJECTIVE

To review and summarize reported adverse events related to the use of porcine small intestine submucosal grafts (Biodesign™) in otologic procedures.

STUDY DESIGN

Retrospective cross-sectional analysis.

SETTING

Food and Drug Administration's Manufacturer and User Facility Device Experience (MAUDE) database.

MATERIAL AND METHODS

The MAUDE database was queried for all medical device reports (MDR) related to otologic use of Biodesign™ (Cook Medical, Bloomington, IN) from January 2016 to November 2022. Adverse events (AEs) were identified by reviewing all reports with the basic search term "Biodesign" and "Biodesign, Otologic". Reports were individually reviewed and categorized with special attention to AEs.

RESULTS

A total of 500 reports were reviewed. Since FDA approval of Biodesign™ in 2016, there have been 5 adverse events reported for use of Biodesign™ during otologic surgery (tympanoplasty, n = 3; stapes surgery, n = 2). All reported events described patient injury, and all cases required at least one revision surgery. Four cases described significant foreign body inflammatory reactions. Complications included hearing loss (n = 3), severe otalgia (n = 2), persistent perforation (n = 2), vertigo (n = 2), and facial paralysis (n = 1).

CONCLUSION

The use of porcine small intestinal submucosal graft has been thought to be a safe and effective option for otologic surgery, with the advantage of availability without graft harvest in minimally invasive endoscopic surgery. However, foreign body or granulomatous reactions have been documented and should be considered prior to its use in otologic surgery.

Comparison of Cartilage Reinforcement and Push-Through Techniques for the Treatment of Large Perforations

Objective: To compare the graft success rate and hearing outcomes of endoscopic cartilage reinforcement perichondrium-cartilage composite graft and push-through techniques for the treatment of large marginal perforations. Study Design: Randomized controlled trial. Materials and Methods: A total of 57 large marginal perforations were prospectively randomized to cartilage reinforcement (n = 29) and cartilage push-through technique (n = 28) groups. The graft success rate, audiometric outcomes, and complications were compared between the 2 groups at 6 months. Results: All patients completed 6 months of follow-up. The graft success rate in the cartilage reinforcement group was significantly higher compared to that in the push-through group (100.0% vs 78.6%, P < .01). Residual perforation was observed in 5 (17.9%) patients, and re-perforation in 1 (3.6%) patient, in the push-through group. The preoperative air-bone gap (ABG) was 17.6 ± 3.5 dB in the cartilage reinforcement group and 16.8 ± 8.4 dB in the push-through group (P > .05). Postoperatively, although the postoperative ABG in the cartilage reinforcement group was higher than that in the push-through group, no significant difference was observed (11.8 ± 4.3 dB vs 8.9 ± 2.5 dB, P > .05). Additionally, no significant difference was found in ABG closure between the 2 groups (6.6 ± 1.9 dB vs 7.9 ± 4.7 dB, P > .05). Conclusion: Cartilage reinforcement myringoplasty is a simpler and more useful technique to achieve graft success compared to cartilage-perichondrium push-through for the treatment of large marginal perforations, and it does not affect hearing levels.

A Prospective Randomised Comparative Study Between Cartilage and Fascia Tympanoplasty in a Tertiary Care Hospital to Look for Better Alternative in High Risk Cases

Introduction

CSOM patients are most commonly managed surgically by type I tympanoplasty using either cartilage shield technique or underlay grafting technique. In our study, we have compared the graft uptake and hearing results of type I tympanoplasty using temporalis fascia and cartilage shield, and also reviewed the literature regarding the results of these two methods.

Materials and Methods

160 patients aged between 15 and 60 years were randomized into two groups of 80 patients each, with odd numbers subjected to conchal or tragal cartilage shield grafting in group I, while in group II with even numbers, the patients underwent temporalis fascia grafting by underlay technique.

Results

Three months post-surgery, the graft uptake was seen in 76 patients (95%) in the cartilage shield group as compared to 58 patients (72.5%) in the temporalis fascia group, which was statistically significant between the two groups [Fisher's exact value = 0.000]. The uptake rate was much higher in cartilage shield graft as compared to fascia graft even in complicated cases like revision tympanoplasty (TP), discharging ear, subtotal perforation and retracted/adhered TP. Also, the hearing improvement in fascia and cartilage shield group was not statistically significant comparing pre- and post-operative patients, indicating that there was not much difference in audiological outcomes between the two groups.

Conclusion

We advocate the use of cartilage shield graft as a substitute for fascia graft in all feasible cases as well as in complicated situations to improve the success rate of type I tympanoplasty, without compromising on the hearing improvement, as seen in our study.

Racial Disparities in Tympanoplasty Surgery: A 30-Day Morbidity and Mortality National Cohort Study

OBJECTIVES

To assess the impact of race and ethnicity on 30-day complications after tympanoplasty surgery.

METHODS

The National Surgical Quality Improvement Program database was queried for tympanoplasty procedures from 2005 to 2019. Demographic, comorbidity, and postoperative complication data were compared according to race using univariate and binary logistic regression analyses.

RESULTS

A total of 11,701 patients were included, consisting of 80.3% White, 3.0% Black, 7.7% Asian, 5.7% Hispanic, 2.5% American Indian/Alaska Native, and 0.8% other. Binary logistic regression model indicated that Black patients had increased odds of unplanned readmittance (p = 0.033; odds ratio [OR], 3.110) and deep surgical site infections (p = 0.008; OR, 6.292). American Indian/Alaska Native patients had increased odds of reoperation (p = 0.022; OR, 6.343), superficial surgical site infections (p < 0.001; OR, 5.503), urinary tract infections (p < 0.001; OR, 18.559), surgical complications (p < 0.001; OR, 3.820), medical complications (p = 0.001; OR, 10.126), and overall complications (p < 0.001; OR, 4.545).

CONCLUSION

Although Black and American Indian/Alaskan Native patients were more likely to have complications after tympanoplasty surgery after adjusting for comorbidities, age, and sex, these results are tempered by an overall low rate of complications. Future studies should be devoted to understanding the drivers of these health inequities in access to otologic care and surgical treatment to improve outcomes and achieve equitable care.

An Exposition on Endoscopic Broad Palisade Cartilage Tympanoplasty: Procedural Illustrations and Connotations in Context of Audiological and Morphological Outcomes

The objective of this study was to evaluate graft take up rate and hearing improvement in type I and type III endoscopic tympanoplasty using broad palisade cartilage graft and to compare the results with other studies who have used single piece cartilage as graft. This retrospective observational descriptive study was done in a tertiary care hospital. This study included 64 cases, who met the inclusion criteria, which were operated over 2 years and were followed for 3 years. The results were evaluated using graft uptake rates and hearing improvement comparing the preoperative and postoperative air conduction threshold (ACT) and air bone gap closure (ABG). The graft take rate was 92.1% and 87.5% at the end of 1 year and 3 years respectively. The preoperative and post-operative air conduction threshold were 35 ± 6.0 dB HL and 17.5 ± 2.7 dB HL in type I tympanoplasty respectively (p value <0.0001) while in type III tympanoplasty, preoperative and post-operative air conduction threshold (ACT) were 43.3 ± 8.6 dB HL and 23.1 ± 4.2 dB HL respectively (p value <0.0001). The preoperative and postoperative air bone gap (ABG) were 29.0 ± 5.6 dB HL and 14.4 ± 4.20 dB HL in type I tympanoplasty respectively (p value <0.0001). In type III preoperative and post-operative air bone gap were 36. 1 ± 7.5 dB HL and 16.4 ± 3.3 dB HL respectively (p value < 0.0001). Endoscopic broad palisade cartilage tympanoplasty has similar outcomes in morphological and audio logical perspectives as single piece cartilage tympanoplasty. Further studies with long term follow up period are required to corroborate the result of this study.

Paediatric Cartilage Tympanoplasty: A Two Handed Technique with Our Endoscope Holder

The aim of the study is to evaluate the functional and anatomical results of paediatric sliced cartilage type 1 tympanoplasty using our endoscope holder. It is Retrospective Non Randomized Clinical Study. A total of consecutive 81 children operated from January 2016 to December 2017 for endoscopic type I sliced cartilage tympanoplasty with endoscope holder were included in the study. The study included 44 males and 37 females. The patients ranged from 8 to 18 years. In early follow up period ranging from 24 to 48 months, the graft take up was seen in 76 follow up giving a success rate of 93.82 percent. The pre-operative air-bone gap was 32.34 ± 2.71 dB and the post-operative mean 4 tone air-bone gap at 1 and 2 years was 9.12 ± 2.37 dB and 9.42 ± 1.38 dB respectively. The study reports the good air bone closure and anatomical closure of perforation with sliced cartilage in paediatric tympanoplasty.

Type 1 Revision Tympanoplasty Using Tragal Cartilage in a Tertiary Care Centre: A Prospective Observational Study

To evaluate graft success rate and hearing outcome in type 1 revision tympanoplasty using tragal cartilage graft. It is a prospective observational study conducted at Department of ENT, Bangalore Medical College and Research Institute from July 2017 to June 2019. Forty four patients between the age group 18-60 years undergoing type 1 revision tympanoplasty, with conductive hearing loss were enrolled.There were 27 males and 17 female patients in the study group. Cartilage tympanoplasty was done using thin tragal cartilage graft . Postoperative hearing gain and graft uptake was assessed at third month. Graft uptake and hearing improvement was assessed 3 months postoperatively in 44 patients. Forty patients had graft uptake (90.90%). The postoperative hearing gain was 7.12 ± 2.99 dB (p = 0.001) which was statistically significant. Tragal cartilage is a good option as graft material in revision cases in terms of ease of graft placement, better graft uptake and audiological outcome with no complications like lateralization of graft, medialization of graft, epithelial pearl formation and anterior blunting.

Reconstruction of the external auditory canal: The tragal flap revisited and review of contemporary reconstructive techniques

BACKGROUND

Primary malignancies arising in the external auditory canal (EAC) are rare and usually are treated surgically. We review techniques to reconstruct the EAC following ablative surgery, and introduce a rarely utilized tragal skin flap which has particular advantages for reconstruction of limited anterior EAC defects.

METHODS

The terms "tragal flap", "external auditory canal", "preauricular tragal flap", "reconstructive techniques" were searched on PubMed and Google Scholar.

RESULTS

Our review identified one description of a tragal flap to reconstruct the EAC following resection of a malignancy. We add an additional case of a preauricular tragal flap to reconstruct the anterior EAC following resection of a recurrent basal cell carcinoma located in the EAC that led to a circumferential defect.

CONCLUSION

There are several surgical techniques that can be utilized to reconstruct the EAC. We describe a novel tragal flap used to reconstruct the anterior EAC following resection of a recurrent tumor.

[Clinical study on repairing subtotal perforation of tympanic membrane with cartilage island technique combined with palisade technique under otoscope]

Objective:To investigate the healing rate of subtotal perforation of tympanic membrane repaired by cartilage island technique combined with palisade cartilage technique under otoscope. Methods:A retrospective analysis was performed on 189 patients with chronic suppurative otitis media who were admitted to the Department of Otolaryngology and Head and Neck Surgery of Hunan Provincial People's Hospital from January 2018 to January 2020. The patients were divided into twogroups, in group onethere were 100 patients treated by senior surgeon, which were divided into two subgroups, Group A （68 cases） were treated with cartilage island technique alone, and Group B （32 cases） were treated with cartilage island technique combined with palisade cartilage technique. In group two there were 89 patients treated by junior surgeons, which were divided into two subgroups. In group C, 50 cases were treated with cartilage island technique alone, and in group D, 39 cases were treated with cartilage island technique combined with palisade cartilage technique. Results:The healing rate of tympanic membrane in group 1 was 96.0% （96/100）, and in group 2 was 87.6%（78/89）.There was statistically significant in group 1 and group 2（χ²=4.504, P=0.034）.The healing rate of tympanic membrane was 94.1% （64/68） in group A, 100%（32/32）in group B, 80.0%（40/50） in group C, and 97.4% （38/39） in group D. There was no statistically significant difference between group A and group B （χ²=1.961, P=0.161）, there was statistically significant difference between group C and group D （χ²=6.149, P=0.013）, and there was statistically significant difference between group A and group C（χ²=5.492, P=0.019）There was no statistical difference between group B and group D（χ²=0.832, P=0.362）. Conclusion:For beginners of tympanoplasty, the use of cartilage island technique combined with palisade cartilage technique in otoscope can significantly improve the success rate of tympanoplasty with subtotal tympanic perforation.

Butterfly Cartilage Tympanoplasty as an Alternative to Conventional Surgery for Tympanic Membrane Perforations: A Systematic Review and Meta-Analysis

OBJECTIVE

To compare the effectiveness of butterfly cartilage tympanoplasty (BCT) with that of conventional surgical approaches in the treatment of tympanic membrane perforations.

METHODS

A systematic search was performed by screening the PubMed, Embase, and Cochrane Library databases up to October 31, 2020. Two coauthors independently identified studies in accordance with the selection criteria. Data were pooled and analyzed via Review Manager version 5.3 and Stata version 12.0 software. The postoperative outcomes were measured and expressed as odds ratios (ORs) and standardized mean differences (SMDs). Additionally, heterogeneity was assessed through the I² statistic.

RESULTS

A total of 15 articles were eligible for final inclusion. The OR values for the graft uptake rate, compared to conventional tympanoplasty, were 1.12 (95%CI: 0.56-2.22, I² = 52%, P = .75) and 1.22 (95%CI: 0.58-2.59, I² = 0%, P = .60), and the OR compared to fat plug myringoplasty was 3.02 (95%CI: 1.04-8.77, I² = 0%, P = .04). The qualitative analysis of the hearing results reflected significant postoperative auditory gains with no significant differences between the BCT and control groups, indicating satisfactory and similar postoperative hearing improvement. Moreover, the operation time was shortened (SMD = -2.19, 95%CI: -2.79 to -1.59, I² = 82%, P < .05), and the postoperative pain was less with the BCT approach.

CONCLUSION

Butterfly cartilage tympanoplasty has satisfactory efficacy in terms of anatomical and functional results in small to medium perforations. It reduces operation time and postoperative pain. However, the effectiveness on large perforation requires further assessment by well-designed studies.

Rare case of ballooning herniation of the tympanic membrane

Herniation of the tympanic membrane is a rare benign malformation of the tympanic membrane into the external auditory canal. It may be asymptomatic or associated with symptoms such as aural fullness, tinnitus, otalgia or hearing loss. We present a case of a symptomatic herniation of the tympanic membrane and its surgical therapy with hernia excision and tympanoplasty. An internal review board exemption was obtained.

Is Ossiculoplasty Necessary in Canal Wall Down Mastoidectomy? Comparison of Clinical Outcomes Between Type 0 Tympanoplasty and Ossiculoplasty

BACKGROUND AND OBJECTIVES

To assess whether the audiological and clinical outcomes of type 0 tympanoplasty (T0) performed using cartilage were comparable with those of ossiculoplasty in patients who underwent canal wall down mastoidectomy (CWDM).

SUBJECTS AND METHODS

This study included patients who had chronic otitis media with cholesteatoma and underwent CWDM with ossiculoplasty involving partial ossicular replacement prosthesis (PORP), total ossicular replacement prosthesis (TORP), or T0. Anatomical success rates and hearing outcomes were analyzed.

RESULTS

Seventy-two patients were included in this study; 29 of them underwent CWDM with T0, 27 underwent CWDM with PORP, while 16 underwent CWDM with TORP. The difference in mean improvement in the air-bone gap (ABG) between the groups was not significant. The differences in the rates of ABG closure to ≤10 dB HL (p=0.030) and ≤20 dB HL (p=0.029) were significant. There were significant differences in improvements in the ABG at 3 kHz among the PORP, TORP, and T0 groups.

CONCLUSIONS

The audiological outcomes of CWDM with ossiculoplasty seemed to be better than those of CWDM with T0 with no significant difference in the incidence of complications following ossiculoplasty and T0.

Endoscopic type 1 tympanoplasty; a composite graft technique for subtotal and total perforations

OBJECTIVE

Demonstrate feasibility of performing endoscopic transcanal type 1 tympanoplasty in total and subtotal perforations, using an underlay technique that minimizes the risk of anterior medialization of the graft. Compare audiometric and clinical outcomes of this technique with our series of endoscopic tympanoplasty with classical underlay grafts, and with previously reported outcomes of microscopic post-auricular lateral graft tympanoplasty and other transcanal techniques.

METHODS

We describe a surgical technique using an L-shaped cartilage and its perichondrium, with exclusive transcanal endoscopic approach. A retrospective review of patients undergoing this technique at the Centenario University Hospital of Rosario, Argentina between January 2017 and December 2019 was performed, and it was compared with a group of patients who underwent endoscopic tympanoplasty with classical underlay technique in a previous period of time. Patients with smaller perforations and other middle ear pathologies that required other techniques were not included in this study. Minimum follow up was 6 months. The main outcome measures were membrane closure rates and hearing results.

RESULTS

73 patients with total or subtotal perforations undergoing endoscopic transcanal tympanoplasty between 2015 and 2019 were included. The group of patients that underwent the technique described showed no anterior medialization of the graft, and better graft take rates. The hearing outcomes were similar in all successful graft patients, with postoperative average air-bone gap of 10db (+  - 10 dB).

CONCLUSION

Transcanal endoscopic tympanoplasty with the technique described is an excellent option for closure of total and subtotal tympanic perforations. The rate of perforation closure is better than endoscopic tympanoplasty with classical underlay graft with similar audiometric outcome.

Intraoperative tragal and conchal cartilage thickness: Comparative study for cartilage tympanoplasty

INTRODUCTION

In conditions like recurrent perforations, atelectatic tympanic membrane and poor eustachian tube function, temporalis fascia graft fails to give the desired result. In such cases cartilage is used for tympanoplasty. It was demonstrated that if the thickness of cartilage is reduced to around 0.5 mm, the sound conduction is comparable to that of normal tympanic membrane with excellent mechanical stability.

AIM

To intra-operatively measure the mean thickness of tragal and conchal cartilage and compare it for age and sex variations.

MATERIAL & METHODS

A total of 114 tragal and conchal cartilage samples of 86 patients were included in the study. Thickness of cartilages was measured intra-operatively after removing the perichondrium from both sides.

RESULTS

Out of 58 tragal cartilages, 32 were from males and 26 from females. Mean thickness was 1.18 ± 0.11 mm among males and 1.12 ± 0.14 mm among females. Out of 56 conchal cartilage taken, 29 were from males and 27 females. Mean thickness among males were 1.38 ± 0.13 mm and 1.35 ± 0.08 mm in females. In 28 patients both tragal and conchal cartilage was taken. Mean thickness of both tragal (1.22 mm) and conchal cartilage (1.36 mm) increased with increase in age. Among 16 males in whom both cartilages were taken, mean thickness of tragal cartilage was 1.25 ± 0.11 mm and conchal cartilage was 1.41 ± 0.12 mm. Similarly among 12 females where both cartilages were taken, mean thickness of tragal cartilage was 1.20 ± 0.13 mm and conchal cartilage was 1.35 ± 0.07 mm.

CONCLUSION

Sliced cartilage tympanoplasty is a relatively better technique. When using cartilage splitter to get sliced cartilage, ideally thickness of every graft should be known. As it is difficult to measure the exact thickness in every case, so knowing the mean for age and sex for cartilage thickness is important to have an idea of which plates to use for a successful outcome of slicing. We concluded that thickness of tragal cartilage is significantly less than the thickness of conchal cartilage. Also there is significant age related difference between mean thickness of cartilages, both for tragal and conchal cartilage. Surprisingly the difference between thickness in male and female is not statistically different.

En Hamac tympanoplasty and canalplasty for optimal type 1 tympanoplasty outcomes

OBJECTIVE

Multiple tympanoplasty techniques have been developed with numerous differences in grafting and approach. This study aimed to improve type 1 tympanoplasty outcomes by using the 'en hamac' technique as well as performing a complete canalplasty for anterior perforations.

METHOD

A retrospective review was performed using the prospective Otology-Neurotology Database tool for otological surgery. All primary type 1 tympanoplasty cases performed for tympanic membrane perforations from 2010 to 2016 were selected for analysis, all performed by one author. Minimal clinical and audiometric follow up was 18 months.

RESULTS

Tympanic membrane perforation closure was achieved in 62 of the patients (96.88 per cent). None of the en hamac cases had residual or recurrent perforation (p = 0.02). The mean remaining air-bone gap was 8.50 dB. The remaining air-bone gap was less than 10 dB in 72.55 per cent, 10-20 dB in 25.49 per cent and more than 20 dB in 1.96 per cent.

CONCLUSION

Using the en hamac technique for anterior perforations as well as systematically performing a complete canalplasty provides multiple surgical advantages with excellent post-operative results.

Long-term results of type I tympanoplasty with perichondrium reinforced cartilage palisade vs temporalis fascia for large perforations: A retrospective study

Objective

To compare the rate of graft uptake and postoperative hearing outcomes of Type I tympanoplasty with perichondrium reinforced cartilage palisade to temporalis fascia for large tympanic membrane (TM) perforations over 5 years follow-up period.

Materials and methods

This was a retrospective comparative study involving patients with chronic otitis media with large TM perforations. The patients underwent type I tympanoplasty using either perichondrium reinforced cartilage palisade (CP group) or temporalis fascia (TF group) as the graft via a transmeatal approach and under local anesthesia. Morphological and functional results were recorded at three- and five years follow-up. Demographic profiles including age and sex, surgery side, contralateral disease and graft uptake rate, as well as hearing outcomes, were compared between the two groups.

Results

At three years follow-up, graft uptake was 94.87% for perichondrium reinforced cartilage palisade and 80.7% for fascia, respectively, (p = 0.67). At five years follow-up, the uptake rate dropped to 87.17% in the CP group, but to 66.6% in the TF group (p=0.019). Hearing improved after surgery in both groups, and showed no significant difference between the two groups.

Conclusion

Over long-term, perichondrium reinforced palisade showed a statistically significant better outcome regarding graft uptake than temporalis fascia in type Itympanoplasty for large TM perforations with comparable audiometric results

Double-Layered (Cartilage Island + Extra Perichondrium) Graft for Type 1 Tympanoplasty

OBJECTIVE

To compare the graft success rates and hearing results of single-layered (composite island) grafting (SLG) vs double-layered (composite plus second layer of perichondrium) grafting (DLG) for over-under type 1 tympanoplasty techniques.

STUDY DESIGN

Retrospective chart review.

SETTINGS

Tertiary center otorhinolaryngology clinic.

SUBJECTS AND METHODS

Medical charts of the patients who underwent type 1 tympanoplasty via the microscopic technique by a single surgeon between 2015 and 2019 were analyzed.

RESULTS

A total of 48 patients were included. The DLG (n = 26) group had higher graft take rates as compared to the SLG group (n = 22) for all patients (P = .038) and for moderate- to high-risk patients according to Middle Ear Risk Index (MERI) scores (P = .029) but not for patients with mild disease (P = .429) or myringosclerotic patients (P = .242). The DLG group exhibited higher air-bone gap closure (C-ABG) values as compared to the SLG group for all patients (P = .018). However, there was no noticeable difference in C-ABG values within the patients with successful grafting (P = .217). Only graft success status had a significant effect on C-ABG values when the multivariate linear regression was performed. (P = .016). Higher MERI scores and presence of myringosclerosis were related to the unsuccessful grafting (P < .01).

CONCLUSION

DLG tympanoplasty is encouraged, especially for patients with higher MERI scores, to increase the graft success rates. Better hearing outcomes of DLG tympanoplasty were related to the higher graft success status of this technique; DLG had no additional hearing effect for patients with successful grafting. Higher MERI scores and presence of myringosclerosis were related to graft failure.

Palisade cartilage tympanoplasty compared to one-piece composite cartilage-perichondrium grafts for transcanal endoscopic treatment of subtotal tympanic membrane perforations: a retrospective study

PURPOSE

The endoscopic approach to tympanoplasty is gaining popularity, but its adoption for the palisade tympanoplasty technique is unstudied. The aim of the present study was to evaluate the effectiveness of endoscopic cartilage palisade tympanoplasty compared to one-piece composite cartilage-perichondrium grafts for tympanic membrane closure in adult patients with subtotal perforations.

METHODS

Retrospective study of 42 adult patients who underwent endoscopic tympanoplasty for a subtotal perforation in a university tertiary referral center from January 2018 to June 2019. Patients underwent transcanal tympanoplasty either with cartilage palisade grafts or with one-piece composite cartilage-perichondrium grafts. Both techniques were compared for graft take rate and audiometric results.

RESULTS

Twenty palisade and 22 single-piece tympanoplasties were analyzed. No statistically significant differences between groups were found in terms of tympanic membrane closure (85% vs. 86.3%, p = 0.5) or hearing improvement.

CONCLUSION

The results of the present study suggest that similar results can be obtained with palisade cartilage grafts compared to the one-piece composite cartilage-perichondrium technique for endoscopic tympanic membrane closure. Further studies with long-term results will be needed to confirm these findings.

Endoscopic Cartilage Myringoplasty with Inside Out Elevation of a Tympanomeatal Flap for Repairing Anterior Tympanic Membrane Perforations

Objective:

We evaluated the graft take rate and hearing gain of endoscopic cartilage myringoplasty with inside out elevation of a tympanomeatal flap for repairing an anterior tympanic membrane perforation.

Study design:

A retrospective case series

Setting:

Tertiary university hospital

Materials and Methods:

The study population consisted of patients with an anterior perforation undergoing endoscopic cartilage myringoplasty with inside out elevation of a tympanomeatal flap. The primary outcome was the graft take rate at 6 months. The secondary outcomes were the air–bone gap (ABG) gain at 3 months and complications.

Results:

A total of 51 patients with a unilateral anterior marginal perforation were included in this study. The mean operation time was 62.2 ± 8.3 minutes. The graft success rate was 92.2% (47/51) at 6 months. The mean preoperative ABG was 28.07 ± 5.13 dB, while the mean postoperative ABG was 12.24 ± 4.89 dB ( P < .05). No patients reported sensorineural hearing loss, altered taste, facial nerve palsy, vertigo, or tinnitus. Two patients with a middle perforation developed postoperative purulent otorrhea that resulted in residual perforations. The cartilage graft was extruded into the anterior annulus in two patients with large perforations that resulted in graft lateralization in one patient and residual perforation in the other.

Conclusions:

Endoscopic cartilage myringoplasty with inside out elevation of a tympanomeatal flap is a useful procedure with a low reperforation rate for repairing anterior perforation.

Success rates for various graft materials in tympanoplasty - A review

Objectives

The aim of this paper is to review how successful each type of grafts is in tympanoplasty.

Methods

Pubmed, Google and the Proquest Central Database at Kırıkkale University were queried using the keywords “graft”, “success” “tympanoplasty”, “success rate” with the search limited to the period 1955 to 2017.

Results

Various types of graft materials including temporalis fascia, cartilage, perichondrium, periosteum, vein, fat or skin have been used in the reconstruction of tympanic membrane (TM) perforation. Although temporalis fascia ensures good hearing is restored, there are significant concerns that its dimensional stability characteristics may lead to residual perforation, especially where large TM perforations are involved. The “palisade cartilage” and “cartilage island” techniques have been stated to increase the strength and stability of a tympanic graft, but they may result in a less functional outcome in terms of restoring hearing. Smoking habits, the size and site of a perforation, the expertise level of the operating surgeon, age, gender, the status of the middle ear mucosa and the presence of myringosclerosis or tympanosclerosis are all important in determining how successful a graft is.

Conclusion

Although temporal fascia is the most commonly used graft material for tympanoplasty, poor graft stability may cause failure. This failure is due to the inclusion of connective fibrous tissue containing irregular elastic fibers present in the grafted fascia. Cartilage grafts offer better ability to resist infection, pressure, and cope with insufficient vascular supply. This means that cartilage grafts are suitable for use in revision cases.

To Compare Short and Long-Term Graft Uptake and Hearing Outcome of Type I Cartilage Tympanoplasty Between Small, Medium and Large Perforations Using Reinforced Sliced Conchal Cartilage

To compare short and long-term graft uptake and hearing outcome of type I cartilage tympanoplasty between small, medium and large perforations using reinforced sliced conchal cartilage. A retrospective study conducted in a tertiary center. Fifty patients who under went type I tympanoplasty were enrolled. Their mean age was 29.30 years and follow-up time was 6 and 18 months. The preoperative, postoperative short-term and long-term hearing and graft uptake results were analyzed. Graft uptake rate was 96% in short-term and 98% in long-term with one residual perforation in medium size, but 100% in small and large perforations (P < 0.01). Short and long-term ABG closure was identical in small and medium size perforation (P = 0.978) (P = 0.734), but, large perforation showed significant improvement in long-term (P = 0.012). Sliced conchal cartilage reinforced with temporalis fascia is a reliable technique for tympanoplasty. In long-term, large perforations have better graft uptake rate and continuous hearing improvement and ABG closure than small and medium perforations.

A Study of Use of Autologous Cartilage in Ossicular Reconstruction

Ossiculoplasty is one of the commonly done and challenging surgery in otology and has been done using various graft materials. Materials such as autologous cartilage (tragal or conchal) or allograft (homograft) of the same tissue and synthetic materials like polyethylene TORP, ceramic and hydroxyapatite PORP or Titanium prosthesis have been used. But the latter synthetic materials are expensive and have high extrusion rates. Autologous cartilage grafts are selected for Ossiculoplasty as they are easy to harvest at the same site of operation, non-toxic, has less extrusion rate, minimum shrinkage and lateralization. The aim of this study is to know the efficacy of cartilage in ossicular reconstruction and to evaluate hearing outcome. It is a prospective study done on patients attending ENT outpatient department at hospitals attached to J.J.M Medical College, Davanagere. 50 patients were included in the study who underwent ossicular reconstruction either with canal wall up or down mastoidectomy with tympanoplasty. Pre-operative mean ABG was 39.3 db whereas 6 months post-operative mean ABG was 31.6 db with mean ABG improvement of 7.7 db which was statistically significant. Hearing improvement is better in cases where stapes suprastructure was present and also in canal wall up mastoidectomy procedures. This study suggests that cartilage graft (tragal and conchal) is effective in cases of ossicular reconstruction in patients of chronic otitis media and gives good hearing gain. It is also a economical option in developing countries.

Rates of success in hearing and grafting in the perichondrium-preserved palisade island graft technique

INTRODUCTION

Various graft materials have been used in the tympanoplasty technique. Cartilage grafts are being used increasingly in recent years.

OBJECTIVE

The aim of this study was to present the comparative outcomes of the perichondrium-preserved palisade island graft technique previously defined by ourselves.

METHODS

We retrospectively compared the hearing and graft success rates in 108 patients with chronic otitis media, who had undergone cartilage tympanoplasty, where both island and perichondrium-preserved palisade graft techniques were used.

RESULTS

The success rates among the study and the control groups with regard to graft take were 97% and 93%, respectively. No significant difference was observed between the groups with regard to the postoperative mean pure tone values, improvement in air-bone gaps and reduction in air-bone gaps to under 20dB. However, better results were observed in the study group.

CONCLUSION

The perichondrium-preserved palisade island graft technique is an easy method with high graft success rates and hearing outcomes.

The Impact of Canalplasty on Outcomes of Medial Graft Tympanoplasty

OBJECTIVE

Both medial and lateral graft techniques are commonly employed in tympanoplasty with acceptable closure rates. Canalplasty is routinely performed to obtain adequate exposure in the lateral graft technique; this usually entails removal of the anterior canal wall skin with subsequent replacement as a free graft. While formal canalplasty can also be performed in conjunction with medial graft technique to improve exposure, it is not commonly described. The current study seeks to examine the impact of canalplasty on outcomes of medial graft tympanoplasty.

METHODS

A retrospective chart review was performed for patients undergoing tympanoplasty for chronic otitis media with the senior author. Audiometric data were recorded both preoperatively and postoperatively. Primary outcome measure was perforation closure with audiometric outcomes examined as secondary outcome measures.

RESULTS

One hundred seventy tympanoplasties without ossiculoplasty were included in our study. The overall rate of perforation closure postoperatively was 77%. Cartilage use portended a higher closure rate (100%) when compared with nonuse (75%) (p = 0.04). The success rates with lateral grafts (94%) and medial grafts with canalplasty (92%) were considerably higher than obtained with medial grafts without canalplasty (69%) (p = 0.005 and 0.02, respectively). In cases with anterior perforations greater than 25% of the tympanic membrane, our results demonstrated a significant advantage in performing canalplasty (p = 0.04).

CONCLUSIONS

Data from the current study suggest that canalplasty offers benefit regarding closure rate in medial graft tympanoplasty. Use of cartilage also portended a higher rate of perforation closure. Canalplasty should be considered when using medial graft techniques if exposure is limited due to bony canal anatomy.

New Cartilage Slicer for Slicing Techniques in Tympanoplasty: Design and Applications

ABSTRACT

Cartilage-perichondrium composite graft is used in middle ear surgery for tympanic membrane, ossicular and for soft wall reconstruction. The thickness of the cartilage is thought to interfere with the sound conduction. In our otology practice for tympanic membrane reconstruction, we prefer the sliced cartilage graft to achieve acoustic benefit. At times in the process of slicing, the cartilage gets wasted if not sliced with a precision slicing instrument. We have designed and developed a multi-purpose cartilage slicer for precise reduction of the thickness of the cartilage. To describe the design of our cartilage slicer and to report our preliminary experience with the cartilage slicer. Descriptive study. The technique of slicing with our new cartilage slicer and its usage has been described in detail. A total number of 689 cartilages in tympanoplasty and mastoidectomy have been sliced with it from 2013 to 2017. Our study reports the technique of slicing the tragal cartilage for tympanoplasty, highlighting its advantages and precision of the cartilages slices obtained. Our cartilage slicer is a good option for cartilage slicing in tympanoplasty.

Long-term outcomes of cartilage-buttressed T-tube tympanoplasty for prolonged middle ear ventilation

OBJECTIVES/HYPOTHESIS

To report on the safety and efficacy of cartilage-buttressed T-tube tympanoplasty for long-term middle ear ventilation, specifically by examining duration of tube survival, as well as adverse events associated with prolonged middle ear intubation, including persistent tympanic membrane perforation.

STUDY DESIGN

Retrospective case series of patients undergoing cartilage-buttressed T-tube tympanoplasty between January 2005 and December 2016 in a tertiary-care neurotology private practice.

METHODS

Patients who underwent cartilage T-tube tympanoplasty with complete pre- and postoperative audiometric data and a minimum follow-up duration of 12 months were analyzed. T-tube survival and adverse events including persistent tympanic membrane perforation were recorded and compared to published data for other long-term middle ear ventilation techniques.

RESULTS

The study cohort included 72 cartilage-buttressed T-tube tympanoplasties in 68 patients. Median tube survival was 34 months (range, 2-131 months). Incidence of persistent tympanic membrane perforation (n = 1) was 1.4% CONCLUSIONS: Cartilage-buttressed T-tube tympanoplasty is a safe and effective means of accomplishing long-term middle ear ventilation with a considerably lower rate of persistent tympanic membrane perforation as compared to alternative methods of prolonged middle ear ventilation.

Boomerang-shaped vs. shield-shaped chondroperichondrial cartilage grafts for type 1 tympanoplasty in children: A study of 121 patients

Many techniques and graft materials have been used for the reconstruction of the tympanic membrane. We conducted a retrospective study to compare anatomic and functional outcomes of type 1 tympanoplasty that we performed with boomerang-shaped chondroperichondrial cartilage grafts (BSGs) and shield-shaped chondroperichondrial cartilage grafts (SSGs) in pediatric patients. Our study population was made up 121 patients-61 boys and 60 girls, aged 7 to 16 years (mean: 12.4)-who had undergone a type 1 tympanoplasty. Patients were divided into two groups according to the grafting technique used; there were 59 patients in the BSG group and 62 patients in the SSG group. Ear examinations were performed at postoperative months 3, 6, 12, and 24, and pure-tone average (PTA) for air-conduction threshold values and air-bone gaps (ABGs) were evaluated at 0.5, 1.0, 2.0, and 4.0 kHz at the same visits. We also investigated the impact of the graft material on functional graft success and intergroup differences (if any) in surgical success. Mean postoperative follow-up periods were 30.5 and 30.2 months in the BSG and SSG groups, respectively. We found that the success rates for tympanic membrane reconstruction were not significantly different in the two groups (91.5 and 88.7%). Postoperatively, the mean PTA and ABG values in both groups at 3, 6, 12, and 24 months were significantly lower than the preoperative values (p < 0.05). There were no significant differences in mean PTA values between the two groups at 3, 6, 12, and 24 months. However, the extent of the decrease in PTA values in the BSG group at 3 months was significantly greater than that of the SSG group (p < 0.05). There were no significant differences in mean ABG values between the two groups at 3, 6, and 12 months, but at 24 months, the value was significantly higher in the BSG group (p < 0.05). Finally, the extent of the decrease in ABG in the BSG group at both 3 and 6 months was significantly greater than that of the SSG group (p < 0.05). We conclude that the BSG procedure is a reliable and safe method of performing pediatric tympanoplasty.

Retraction pocket excision with cartilage grafting as a preventive surgery for cholesteatoma

Aims

The goal of the present study is to summarize our experience on surgical management of retraction pockets (RP) as a preventive tool against cholesteatomas.

Methods

Twenty-five ears have been followed up for a mean period of 6.16 ± 4.35 years (from 1 to 17 years). The sample presented a mean age of 47.56 ± 19.11 years (from 16 to 73 years). All patients underwent cartilage graft surgery. Furthermore 10 (40%) underwent tympanoplasty (TPL) type I, 14 (56%) TPL type II and 1 (4%) TPL type V.

Results

Eleven ears (44%) showed cholesteatoma: all these cases were stage III according to Charachon staging, and stage IV or V according to Gersdorff classification. Twelve patients (48%) showed erosion of the ossicular chain. Of these, five were associated with cholesteatoma and seven only with retraction. The recurrence rate of cholesteatoma was 12%. None of the patients with a stage II or III RP (according to Gersdorff classification) developed cholesteatoma. The recurrence of RP was 0%.

In regards to literature review, seven references were selected. These studies showed a success rate ranging from 79.1% to 88%, while recurrences of RP varied from 6.4% to 13%. Only one study specified a recurrence rate of cholesteatoma of 28%.

Conclusions

Surgical treatment of stages II and III RP is an effective tool to prevent cholesteatoma formation. The presence of keratin accumulation and cholesteatoma at the RP (stages IV and V, according to Gersdorff) are the real predictors of poor prognosis.

Surgical Success of Tympanoplasty Using Composite Tragal Cartilage in Chronic Otitis Media

This study aims to investigate the preoperative, postoperative airway hearing threshold levels, and perforation closure rates in patients who underwent primary tragal cartilage tympanoplasty. One hundred seventy-one patients who had chronic otitis media without cholesteatoma underwent primary tragal cartilage tympanoplasty with endaural approach by using underlay technique. Preoperative and postoperative airway hearing threshold levels at 500, 1000, 2000, 4000 Hz frequencies in 8 to 99 months' follow-up were found and compared with each other. Postoperative perforation closure rates were also investigated. At 500 Hz in 112 patients, at 1000 Hz in 106 patients, at 2000 Hz in 96 patients, and at 4000 Hz in 80 patients, more than 9.5 dB airway hearing gain was determined. The authors found their postoperative perforation closure rate as 84.8%. In conclusion, tragal cartilage tympanoplasty may be chosen as the primary operation technique in primary chronic otitis media patients and by this technique perforation closure rates are also acceptable in addition to satisfactory hearing gain.

Long-term Outcomes After Secondary Mastoid Obliteration

OBJECTIVES

To assess long-term outcomes after secondary mastoid obliteration.

STUDY DESIGN

Case series with chart review.

SETTING

Tertiary care center.

PATIENTS

Adult patients (20-80 yr of age) undergoing secondary mastoid obliteration.

OUTCOME MEASURES

Hearing results (improvement in pure-tone average air-bone gap [PTA-ABG] from baseline) at the time of postoperative audiometry and at least 5 years after surgery, anatomic outcomes (rate of successful tympanic membrane graft healing), and the incidences of observed complications.

RESULTS

An average improvement in PTA-ABG by 16.9 dB (p = 1.8 × 10) was noted. Postoperatively, the PTA-ABG was successfully closed to ≤20 dB in 39.5% (17/43) of patients. The average final PTA-ABG (obtained at least 5 years after surgery) was 25.3 dB, which was also a significant improvement over the preoperative baseline PTA-ABG (p <<< 0.01). Significant complications were observed in 14.0% (6/43) of patients, with 9.3% (4/43) requiring a subsequent surgery. Although 69.8% (30/43) of patients experienced otorrhea preoperatively, otorrhea was only observed in 4.7% (2/43) at any point in time postoperatively.

CONCLUSION

Secondary mastoid obliteration with reconstruction of a more natural posterior canal wall, cartilage tympanoplasty, and ossicular chain reconstruction is a hybrid technique that allows for creation of a safe, dry ear with significant, long-term improvement in hearing and functional outcomes in patients with unstable mastoid cavities.

The palisade cartilage tympanoplasty technique: a systematic review and meta-analysis

Background

Tympanoplasty is a common procedure performed by Otolaryngologists. Many types of autologous grafts have been used with variations of techniques with varying results. This is the first systematic review of the literature and meta-analysis with the aim to evaluate the effectiveness of one of the techniques which is gaining popularity, the palisade cartilage tympanoplasty. PubMed, EMBASE, and Cochrane databases were searched for "palisade", “cartilage”, “tympanoplasty”, "perforation" and their synonyms.

Main body of abstract

In total, 199 articles reporting results of palisade cartilage tympanoplasty were identified. Five articles satisfied the following inclusion criteria: adult patients, minimum 6 months follow-up, hearing and surgical outcomes reported. Studies with patients undergoing combined mastoidectomy, ossicular chain reconstruction, and/or other middle ear surgery were excluded. Perforation closure, rate of complications, and post-operative pure-tone average change were extracted for pooled analysis. Study failure and complication proportions that were used to generate odds ratios were pooled. Fixed effects and random effects weightings were generated. The resulting pooled odds ratios are reported. Palisade cartilage tympanoplasty has an overall take rate of 96% at beyond 6 months and has similar odds of complications compared to temporalis fascia (OR 0.89, 95% CI 0.62, 1.30). The air-bone gap closure is statistically similar to reported results from temporalis fascia tympanoplasty.

Conclusions

Cartilage palisade tympanoplasty offers excellent graft take rates and good postoperative hearing outcomes for perforations of various sizes and for both primary and revision cases. This technique has predictable, long-term results with low complication rates, similar to temporalis fascia tympanoplasty.

Type 1 Tympanoplasty by Cartilage Palisade and Temporalis Fascia Technique: A Comparison

(1) To compare graft take up of type-1 tympanoplasty with cartilage palisade technique with those of type-1 tympanoplasty using autotemporalis fascia. (2) To compare hearing results of type 1 tympanoplasty with cartilage palisade technique with those of type-1 tympanoplasty using autotemporalis fascia. A prospective clinical study. It consisted of 60 patients divided into two groups of 30 patients each. After randomization 30 patients underwent type 1 tympanoplasty using cartilage palisade technique and 30 underwent type 1 tympanoplasty using autotemporalis fascia. In follow up, pure tone audiogram were carried out at 2nd, 4th and 6th month. Clinical assessment was done at 2nd 4th and 6th month. The graft uptake rate between the group 1 and group 2 are 93.33 and 90% respectively. As p value was greater than 0.05 so statistically there is no significant difference between the two group. The post operative air bone gap of the two groups were compared using student t test. The pre op mean of group 1 was 32.5 db and pre op mean of group 2 was 30.66 db. The post op mean of group 1 was 21.33, with standard deviation of 3.6984 and standard error of 0.67523. The post op mean of group 2 was 21.09 with standard deviation of 3.29 and standard error of 0.58261. t value was 0.1357. Analysis was done using student t test and p value was found to be greater than 0.05. p value is greater than 0.05 which shows that there is no statistical difference between the two groups. This study establishes the fact that hearing results after performing type 1 tympanoplasty by autotemporalis fascia when compared with type 1 tympanoplasty performed by cartilage palisade technique showed similar hearing gain and post operatively graft take up rate was also similar in two groups. The disadvantage of reducing the mechanical vibration of the tympanic membrane was overcome by the palisade reconstruction of the tympanic membrane. This study definitely emphasizes upon usage of new grafting materials in reconstruction of tympanic membrane, with similar, if not better functional results, without compromising the acoustic transfer characteristics.

Endoscopy-Assisted Ear Surgery for Treatment of Chronic Otitis Media With Cholesteatoma, Adhesion, or Retraction Pockets

The objective of this study was to analyze the results of endoscopy-assisted ear surgery for the treatment of chronic otitis media with cholesteatoma, adhesion, or retraction pockets.Fifty-one patients who underwent oto-endoscopy-assisted canal wall up tympanomastoid surgery and/or limited anterior atticotomy with tympanoplasty for chronic otitis media with cholesteatoma, adhesion, or retraction pocket from 2006 to 2013 have been included in this study. Eradication of the disease from the middle ear and mastoid air cells was achieved by combination of the oto-microscobic and oto-endoscopic approaches. Second look surgery was performed 18 months later from the initial surgery in selected patients. Age, gender, pre-/postoperative otoscopy findings/audiograms, type of the used prostheses, and follow-up time were obtained from the patient's file. Anatomic integrity rates of the tympanic membrane, the mean gains of air bone gap, on pure-tone audiogram at 4 frequencies and existence of the residual disease were reviewed parameters. Functional evaluation was made in patients with intact tympanic membrane.Of the 51 patients, the ratios of the chronic otitis media with cholesteatoma and isolated adhesive otitis or retraction pocket cases were 74.5% (38/51) and 25.5% (13/51), respectively. Ossicular chain reconstruction was made with PORP in 27 patients and TORP in 20 patients, whereas the ossicular chain was intact in 4 patients. Anatomic integrity rates of the tympanic membrane were 90.2% (46/51). The overall (n = 46) pre-/postoperative mean ABG obtained at 4 frequencies were 28.3 ± 12.26 and 9.18 ± 5.68 dB (P < 0.0001) respectively. Residual cholesteatoma rate was 10.5% (34/38) for chronic otitis media with cholesteatoma patients. However, there was no recurrence or new cholesteatoma formation in isolated retraction pockets or adhesive otitis patients.Oto-endoscopic eradication of the cholesteatoma or epithelial tissue from hidden area after the all visible cholesteatoma removal by oto-microscope improves the quality of surgery, significantly decreases the frequency of the canal wall-down procedure and posterior tympanotomy requirements with acceptable residual cholesteatoma rates.

Inlay Butterfly Cartilage Tympanoplasty: Anatomic and Functional Results

To evaluate anatomic/functional results of inlay butterfly cartilage tympanoplasty and compare those with the results of over-underlay perichondrium-cartilage island or temporalis fascia tympanoplasties. Patients who operated for primary type 1 tympanoplasty (n = 78) with inlay butterfly cartilage (n = 25), over-underlay perichondrium-cartilage island (n = 36) or over-underlay temporalis fascia (n = 17) graft from January 2005 to January 2015 were included in the study. Age, gender, pre-/postoperative otoscopy findings/audiograms, and follow-up time were obtained from the patient's file. Anatomic integrity rates of the tympanic membrane, the mean gains of air bone gap on pure tone audiogram at four frequencies (0.5, 1, 2, 4 kHz) and complications were reviewed parameters. Functional evaluation was made in patients with intact tympanic membrane. Anatomic integrity rates of the tympanic membrane was 92.00% for inlay butterfly cartilage tympanoplasty, 91.67% over-underlay perichondrium cartilage island tympanoplasty and 88.2% over-underlay fascia tympanoplasty. The mean gains of air bone gap on pure tone audiogram for the inlay butterfly cartilage, over-underlay perichondrium cartilage island and over-underlay fascia graft group were 11.28, 12.84 and 12.66 dB respectively. Inlay butterfly cartilage tympanoplasty is a reliable and simple technique with satisfactory outcomes in selected cases. The anatomic and functional results after inlay butterfly cartilage tympanoplasty are parallel to the results of over-underlay perichondrium-cartilage island or temporalis fascia tympanoplasties.

Outcomes of type I tympanoplasty using a cartilage shield graft in patients with poor prognostic factors

OBJECTIVE

Although fascia is widely used as the grafting material in tympanoplasty (TP), unsatisfactory outcomes can result in patients with poor prognostic factors. Recently, cartilage has emerged as a graft material in TP. This study examined the operative outcomes of type I TP using a cartilage shield graft (CSG) in patients with poor prognostic factors.

METHODS

This study reviewed the medical records of patients who underwent type I TP using CSG performed by the same surgeon, with over 24 months of follow-up.

RESULTS

There were 94 patients (mean age 46 years). Preoperatively, 39 patients had near-total perforation, 29 had a previous TP or myringoplasty, 14 had adhesive otitis media, and 12 had a marginal perforation covering ≥50% of the tympanic membrane area. The mean postoperative air-bone gap was significantly (p<0.0001) reduced compared to preoperative measurements. Postoperatively, tympanic membrane perforation occurred in 2.1% and otorrhea in 6.4%. There were no cases of retraction, adhesion, or lateralization. One subject complained of autophonia and ear fullness.

CONCLUSION

Type I TP using CSG has excellent surgical results and minimal complications, even in patients with poor prognostic factors, and should thus be considered in those patients.

Use of tragal cartilage grafts in rhinoplasty: An anatomic study and review of the literature

We conducted a cadaveric study to determine the size of cartilage grafts that can be taken from the tragus without distorting tragal anatomy. Our subjects included 7 fresh cadavers-3 male and 4 female (age at death: 61 to 87 yr). Tragal cartilage grafts were harvested while leaving the lateral 3 mm of the tragal cartilage in situ to preserve the anatomic shape of the tragus. The grafts were measured and their dimensions recorded. The craniocaudal dimensions of the tragal cartilages ranged from 15 to 30 mm (mean: 21.6), and the width of each specimen ranged from 10 to 23 mm (mean: 15.3). The thickness of the cartilage was approximately 1 mm. The grafts were slightly curved along their long axis. We also review the literature regarding the dimensions of different grafts used in rhinoplasty, knowledge of which can help in preoperative planning. Tragal cartilage grafts have been used as shield, alar contour, alar batten, lateral crural onlay, dorsal onlay, and infratip lobule grafts. When a straight and/or thick graft is needed, two strips of tragal cartilage can be sutured in a mirror-image configuration.

Therapeutic Mastoidectomy in the Management of Noncholesteatomatous Chronic Otitis Media

Objective

Despite evidence that therapeutic mastoidectomy does not improve outcomes in noncholesteatomatous chronic otitis media, it remains widely performed. An up-to-date systematic review is undertaken and conclusions drawn regarding the best evidence-based practice of its management.

Data Sources

PubMed, Google Scholar, Medline Embase, Cochrane, and Web of Science.

Review Method

A combination of the following words was used: chronic otitis media, chronic suppurative otitis media, COM, CSOM, mastoidectomy, tympanoplasty, atelectasis, retraction, tympanic perforation, and therapeutic.

Results

From 1742 studies, 7 were selected for full analysis with respect to the benefit of mastoidectomy in the management of active and inactive mucosal chronic otitis media. Most were retrospective studies, with 1 prospective randomized controlled trial available. Overall, there was no evidence to support routine mastoidectomy in conjunction with tympanoplasty in chronic otitis media. For ears with sclerotic mastoids, the evidence suggested that there may be some benefit as a staged procedure. Two studies were analyzed for the benefit of mastoidectomy in addition to tympanoplasty for the management of the atelectatic ear (inactive squamous chronic otitis media). The conclusion was also that mastoidectomy added no benefit.

Conclusions

Examination of the available literature supports the notion that therapeutic mastoidectomy does not lend any additional benefit to the management of noncholesteatomatous chronic otitis media. This has implications for patient care, both clinically and financially. Further research, ideally in the form of a prospective, multi-institutional, geographically wide, ethnically diverse, randomized controlled trial, is needed to further support this notion.

Comparison of results of graft uptake using tragal cartilage perichondrium composite graft versus temporalis fascia in patients undergoing surgery for chronic otitis media - squamous type

BACKGROUND

To assess, analyze and compare the results of graft uptake using Tragal Cartilage-Perichondrium Composite (TCPC) graft with Temporalis Fascia (TF) graft in patients who undergoing surgery for chronic otitis media - squamous type.

METHODS

Patients aged 13 years and above with diagnosis of chronic otitis media - squamous type undergoing modified radical mastoidectomy, either primary or revision surgery with grafting of tympanic membrane (TM) and patients undergoing excision of postero-superior retraction pocket (PSRP) were included in this study. Patients were divided in two groups: Group A-patients undergoing TCPC graft and Group B -patients undergoing TF graft. Graft uptake results were assessed between 8-12 weeks of surgery.

RESULTS

In both Groups there were 30 patients each. In Group A successful graft uptake was seen in 27 patients (90 %) and failure of graft uptake was seen in 3 patients(10 %). In Group B successful graft uptake was seen in 28 patients (93.3 %) and failure in 2 patients (6.67 %).Out of the total 60 patients, 11 patients had PSRP. All 6 patients with PSRP in Group A had successful graft uptake and no retraction. Among the 5 patients with PSRP in Group B all patients had sucessful graft uptake, however, in 2 patients retraction of the tympanic membrane was seen similar to the preoperative findings.

CONCLUSIONS

There was no statistical difference (p = 0.433) between the use of temporalis fascia or tragal cartilage perichondrium in patients undergoing surgery for chronic otitis media - squamous type.

The role of tympanostomy tubes in surgery for acquired retraction pocket cholesteatoma

OBJECTIVE

1. To determine whether intraoperative tympanostomy tubes (TT) during surgery for acquired retraction pocket cholesteatoma (ARPC) can decrease recurrence of ARPC and retraction pockets (RP). 2. To determine the need for subsequent TT in children that did not initially receive TT.

STUDY DESIGN

Retrospective review of children who underwent primary surgery for ARPC.

SETTING

Tertiary care children's hospital.

SUBJECTS AND METHODS

Audiometry, operative reports, office findings, and recurrence of ARPC and RP were analyzed. Univariate analysis with Fisher's exact test, Wilcoxon rank-sum and t test, as well as multivariate analysis with logistical regression, were used for statistical analyses.

RESULTS

21 patients had TT at initial surgery and 34 patients did not. The recurrence of ARPC was 24% for the TT Group versus 44% for the no TT group (p=0.09). The incidence of RP was 33% in the TT group versus 41% in the no TT groups (p=0.35). 35% of the no TT group subsequently required TT. Audiometric outcomes were not different between groups. TT placement did not significantly affect the odds of recurrent ARPC and RP (95% CI 0.12-1.83, p=0.28 for ARPC and 95% CI 0.30-4.60, p=0.82 for RP). However, the odds of recurrent ARPC and RP were significantly increased in children with stapes and malleus erosion by cholesteatoma. Children with stapes and malleus involvement had 5.28 and 11.8 times higher odds of recurrent ARPC compared to those without ossicular erosion (95% CI 1.09-25.6, p=0.04 stapes and 95% CI 1.58-88.3, p=0.02 malleus). Similarly, children with malleus involvement had an 18.6 times higher odds of recurrent RP (95% CI 1.62-214, p=0.02) compared to those who did not. Incus erosion was not a significant predictor for recurrent ARPC and RP.

CONCLUSION

There was no statistical difference in recurrence or audiometric outcomes between patients who underwent TT versus those who did not during initial surgery for ARPC. However malleus and stapes erosion were significantly associated with recurrent ARPC and RP. These findings suggest that TT at initial ARPC surgery did not play a role in preventing recurrence, but malleus and incus erosion, was predictive of recurrent disease. A larger, prospective study of TT at initial surgery for ARPC is needed.

Fascia compared to one-piece composite cartilage-perichondrium grafting for tympanoplasty

OBJECTIVE

To evaluate the effectiveness of type 1 tympanoplasty with one-piece composite cartilage-perichondrium (CCP) grafts compared to temporalis fascia (TF) grafts for tympanic membrane (TM) closure and hearing improvement in adult patients with a subtotal TM perforation and chronic otitis media (COM).

DATA SOURCES

PubMed, Embase, Cochrane Library.

REVIEW METHODS

A systematic search was conducted. Relevance and validity of selected articles were assessed. Studies that scored moderate or high on relevance were included, and relevant data for both outcomes were extracted. For the outcome of TM closure, absolute risk differences (RD), relative risks, and number needed to treat with their respective 95% confidence intervals were calculated when possible.

RESULTS

We retrieved 3,783 unique studies. Ten studies satisfied the eligibility criteria. Four studies of moderate validity showed RD ranging from 0.08 to 0.13 in favor of the CCP graft compared to the TF graft for TM closure 1 year or more postoperatively, but this was not statistically significant. Five studies of moderate to high validity showed no clinically relevant difference in hearing improvement between both intervention groups at a minimum follow-up of 3 months. The relative air-bone gap closure ranged from 5.7 to 11.5 dB in the TF group and from 8.9 to 12.7 dB in the CCP group.

CONCLUSIONS

There is no evidence of superiority of one-piece CCP grafting over TF grafting in type 1 tympanoplasty regarding complete closure of a subtotal perforated TM 1 year or more postoperatively or hearing improvement at a minimum of 3 months follow-up. Laryngoscope, 126:1662-1670, 2016.

Endoscopic "Push-Trough" Technique Cartilage Myringoplasty in Anterior Tympanic Membrane Perforations

OBJECTIVES

To evaluate endoscopic push-through technique cartilage myringoplasty results.

METHODS

This prospective study was performed on patients with anterior tympanic membrane perforations and endoscopic push-through technique cartilage myringoplasty was performed between 2011 and 2013. The patients who did not have any cholesteatoma or otorrhea in the previous 3 months, and had an air bone gap ≤25 dB in their preoperative audiograms were included in the study. They were followed up with endoscopic examination and audiograms at 2nd, 6th, 12th, and 24th postoperative months. Pure tone averages were calculated at 0.5, 1, 2, and 4 kHz frequencies.

RESULTS

Of 32 patients, 19 were females and 13 were males. The mean age was 40.3 years (range, 16 to 62 years), and the mean follow-up period was 12.4 months (range, 6 to 24 months). Graft success rate was 87.5% in this study. Preoperative mean air conduction hearing threshold was 25.9 dB, and the mean air-bone gap was 11.9 dB while these values improved to 19.5 dB and 5.3 dB respectively in the postoperative period. The mean hearing gain was 6.4 dB. The analysis of preoperative and postoperative mean air conduction thresholds and air bone gap values of the patients revealed statistically significant differences.

CONCLUSION

Underlay cartilage myringoplasty with endoscopic push-through technique in anterior quadrant tympanic membrane perforations is an effective, minimally invasive and feasible method.

Average thickness of tragal cartilage for slicing techniques in tympanoplasty

BACKGROUND

Cartilage-perichondrial grafts are often used for tympanic membrane and middle-ear reconstructions. Tragal and conchal cartilages are most frequently used for this purpose. Studies have shown that slicing the cartilage to less than 0.5 mm thickness improves acoustic benefit. However, the thickness of the cartilage in a given population may not be uniform.

OBJECTIVE

This descriptive cross-sectional study aimed to determine the average thickness of tragal cartilage (in terms of age and sex) in an Indian population.

METHOD

A prospective study of 61 tragal cartilages harvested during serial tympanoplasty and modified radical mastoidectomy were analysed according to thickness.

RESULTS

The total average thickness of tragal cartilage was 1.228 ± 0.204 mm in males and 1.090 ± 0.162 mm in females. The overall thickness was 1.018 ± 0.139 mm in those aged less than 15 years, 1.139 ± 0.238 mm in those aged 15-30, and 1.189 ± 0.155 mm in those aged over 30 years.

CONCLUSION

The findings help us to determine age-related cartilage thickness for slicing techniques in tympanoplasty.

Comparative study of sliced tragal cartilage and temporalis fascia in type I tympanoplasty

OBJECTIVE

To compare anatomical and audiological results using sliced tragal cartilage and temporalis fascia in type I tympanoplasty.

METHOD

A retrospective review was undertaken of primary tympanoplasties using sliced tragal cartilage and temporalis fascia from May 2005 to January 2008. In total, 223 ears were operated on using sliced tragal cartilage graft and 167 using temporalis fascia. Statistical analysis of the outcome data was performed.

RESULTS

At the two-year and four-year follow ups, successful closure of the tympanic membrane was achieved in 98.20 per cent and 97.75 per cent, respectively, of the cartilage group compared with 87.42 per cent and 82.63 per cent, respectively, of the temporalis fascia group. At the four-year follow up, the average air-bone gap was 7.10 ± 3.01 dB in the cartilage group and 8.05 ± 3.22 dB in the temporalis fascia group.

CONCLUSION

The overall success rate for primary cartilage tympanoplasty is higher when using sliced cartilage than with temporalis fascia grafting.

Diseases of the middle ear in childhood

Middle ear diseases in childhood play an important role in daily ENT practice due to their high incidence. Some of these like acute otitis media or otitis media with effusion have been studied extensively within the last decades. In this article, we present a selection of important childhood middle ear diseases and discuss the actual literature concerning their treatment, management of complications and outcome. Another main topic of this paper deals with the possibilities of surgical hearing rehabilitation in childhood. The bone-anchored hearing aid BAHA(®) and the active partially implantable device Vibrant Soundbridge(®) could successfully be applied for children. In this manuscript, we discuss the actual literature concerning clinical outcomes of these implantable hearing aids.
