Comparison of type I tympanoplasty with acellular dermal allograft and cartilage perichondrium

Abstract

Background: Acellular dermal allograft (AlloDerm) and cartilage perichondrium are two common materials used for repair of tympanic membrane perforations (TMPs). To date, comparative evaluations of their efficacy have rarely been reported.

Aim/objectives: To compare anatomical and audiological outcomes between AlloDerm and cartilage perichondrium in type I tympanoplasty.

Methods: A total of 61 patients of TMP were studied. In total, 27 patients (Group 1) underwent AlloDerm myringoplasty, and the remaining 34 patients (Group 2) underwent perichondrium myringoplasty. Operating time, closure rate and hearing gain were compared between Groups 1 and 2.

Results: Successful closure rates at 6-month follow-up were 88.9% (Group 1) and 82.4% (group 2). The average improvement of air-bone gap (ABG) was 13.5?±?11.8?dB for Group 1 and 13.1?±?13.1?dB for Group 2. The difference in between preoperative and 6 months postoperative ABG values was statistically significant (p?<?.001).

Conclusions and significance: Success rates and improvement of hearing level were similar for the AlloDerm (Group 1) and the cartilage perichondrium (Group 2) groups. However, AlloDerm requires shorter operative time and avoids the incisions in the harvest of allografts. Our results suggest that AlloDerm can be recommended as an attractive alternative to cartilage grafts.     

Hearing results after type III tympanoplasty: incus transposition versus PORP. A systematic review

Objective: The objective of this study is to compare hearing improvements in the air-bone gap (ABG) after type III tympanoplasties, comparing between incus transposition (IT) and partial ossicular replacement prosthesis (PORP).

Materials and methods: Publications in English were searched in PUBMED database and were systematically reviewed. A total of 14 articles were included, obtaining 1055 patients, 614 for the IT group and 441 for the PORP group. Preoperative ABG, postoperative ABG, dB gain and ABG closure rate were compared.

Results: IT group: preoperative ABG of 31.74?dB (SD 10.51); postoperative ABG of 18.97?dB (SD 10.6); dB gain of 12.76?dB (SD 14.97); and ABG closure rate of 64.48%. PORP group: preoperative ABG of 28.02?dB (SD 10.47); postoperative ABG of 16.27?dB (SD 10.45); dB gain of 11.75 (SD 15.02); and ABG closure rate of 71.32%. No significant statistical difference was found in dB mean gain between groups (p?>?.05), although a difference was found in the ABG closure rate between groups favouring PORP series (p?Conclusion: An improvement in hearing results was observed within both groups after type III tympanoplasty. There is no difference in decibels gained between both ossiculoplasty materials, but a better closure rate (%) was observed in the PORP group.     

Is type 1 tympanoplasty effective in elderly patients? Comparison of fascia and perichondrium grafts

Abstract

Background: Tympanoplasty is regularly performed in various ages but data about the procedure in elderly is insufficient.

Objectives: To compare the success rates and hearing outcomes of fascia and perichondrium grafts used for tympanoplasty in patients >65 years and to evaluate the prognostic factors affecting the success of tympanoplasty.

Methods: Reviewing records of 49 elderly patients underwent tympanoplasty, two groups were constituted: perichondrium (25 patients) and fascia (24 patients) groups. Ages, genders, perforation sides, type and location of perforation, graft success rates, functional success rates and air–bone gap (ABG) gains were compared.

Results: Overall graft success rate was 85.7%. After a mean follow-up of 23.3?±?8.32 months, overall mean ABG gain was 11.33?±?8.42?dB. Overall median postoperative ABG value (9?dB) was significantly lower compared to the median preoperative value (24?dB) (p?<?.001). Graft success rate was higher in perichondrium group (96%) compared to fascia group (75%) (p?=?.04). Functional success rate did not significantly differ between perichondrium (68%) and fascia groups (62.5%) (p?=?.68).

Conclusion and significance: Tympanoplasty is an effective procedure with a graft success rate of 85.7% in elderly. Both fascia and perichondrium are suitable materials; however, perichondrium had higher success rate.

Microdrill stapedotomy for otosclerosis with small and large preoperative air-bone gap: a retrospective comparison of results

Abstract

Background: In otosclerosis mixed hearing loss is the most frequent symptom and arises when the focus involves the stapes footplate. Surgeons usually prefer to wait a minimum air-bone gap of 25 – 35?dB before surgery.

Objectives: To evaluate the outcome of microdrill stapedotomy for otosclerosis in patients with a preoperative air-bone gap (ABG) <25?dB versus patients with a preoperative gap ≥ 25?dB.

Material and methods: For this retrospective study, the outcomes and complications after microdrill stapedotomy were compared between adult patients with a preoperative small ABG (n?=?127, ABG <25?dB) and those with a large ABG (n?=?254, ABG ≥25?dB).

Results: The postoperative ABG was significantly smaller than the preoperative ABG (p?<?.05) in both groups; there were no differences in complications rates (severe sensorineural hearing loss, footplate fracture or early postoperative vertigo) between the two groups.

Conclusions: Our findings show that microdrill stapedotomy is safe and can be performed even in patients with a preoperative small ABG without increasing the risk of sensorineural hearing loss due to inner ear damage.     

Comparison of various bone cement ossiculoplasty techniques and functional results

Objective: In this study, functional results of different bone cement ossiculoplasty techniques are compared.

Methods: Retrospective case review at a tertiary referral center. Patients who underwent middle ear surgery and bone cement ossiculoplasty between 2006–2012 were included. A total of 52 patients, including 30 patients with ‘Incus to stapes’ (Group 1) and 13 patients with ‘malleus to stapes’ (Group 2), five patients with ‘incudoplasty?+?stapedotomy’ (Group 3), and four patients with ‘malleus to incus’ (Group 4) ossiculoplasty were enrolled in the study. Pre-operative and post-operative audiological findings of each group were evaluated.

Results: The mean hearing gain (the difference between pre-operative and post-operative air bone gap (ABG)) was 13?dB for Group 1, 30?dB for Group 2, 24?dB for Group 3, and 9?dB for Group 4. The pre-operative air pure tone averages (PTA) of groups 1, 2, and 3 improved significantly in the post-operative period (p?Conclusions: The results showed that glass ionomer cement is a simple and effective method for reconstruction of ossicular discontinuity in various ossicular chain pathologies and can be an alternative to conventional rebridging techniques such as sculpted incus interposition or partial ossicular replacement prosthesis (PORP).     

Results of endoscopic cartilage tympanoplasty procedure with limited tympanomeatal flap incision

Objective: The aim of this study was to evaluate the outcomes of this minimally invasive tympanomeatal incision technique performed during endoscopic transcanal cartilage tympanoplasty.

Study design: Prospective clinical study.

Methods: Eighty-seven patients (87 ears) who had TM perforation with noncomplicated COM were included. All of the patients were operated with the endoscopic transcanal cartilage tympanoplasty technique. All of the data were prospectively collected. These included demographic data, date of the surgery, preoperative and postoperative pure-tone audiometry (PTA), localization of TM perforation and graft healing success.

Results: Mean follow-up time was 14.76?±?4.32 months. Graft-healing rate was 100%. Mean air bone gap level improvement (dB HL) at 0.5, 1, 2 and 4?kHz were 13.87?±?7.30?dB HL, 9.09?±?7.59?dB HL, 9.74?±?6.40?dB HL and 7.46?±?6.37?dB HL, respectively. At all frequencies, there was significant difference between pre and postoperative mean air bone gap levels (p?p?>?.05).

Conclusions: Endoscopic ear surgery has successful surgical outcomes with low complication rates. In this study, the outcomes of limited tympanomeatal flap incision was discussed. It is suggested that this technique is reliable with good hearing results with low postoperative complications rates.     

Utilization of incus with bone cement for total ossicular reconstruction

Abstract

Background: Total ossicular chain reconstructions are performed to connect mobile stapes footplate and tympanic membrane. Data on the use of incus for total ossicular reconstruction is quite limited in the literature.

Objective: The main objective of this study is to describe a novel surgical method that utilizes incus with bone cement to stabilize the ossicular chain for total ossicular reconstruction.

Materials and methods: 16 patients who underwent total ossicular reconstruction using our method were included in this study. We evaluated hearing by comparing preoperative and postoperative air-bone gap (ABG), air conduction (AC) and bone conduction (BC). The percentage of patients achieving ABG ≤20?dB was determined.

Results: The mean preoperative ABG was 35.3?±?8.2 and postoperative ABG decreased significantly to 23.7?±?7.6 (p?<?.001). The mean preoperative AC (57.5?±?10) decreased significantly postoperatively to (46.5?±?13.3)(p?=?.014). There was not any difference between pre- and post-operative BC. We achieved successful hearing results (ABG ≤ 20dB) in 44% of patients.

Conclusion: The use of incus with bone cement stabilization for total ossicular reconstruction seems a feasible option. Good hearing outcomes, and low cost, complication, and extrusion rate may be the main reasons to prefer this method.     

Surgical results of modified canal wall down tympanoplasty

Conclusion: Patients with mastoiditis and chronic suppurative otitis media which has small mastoids that make them ideal candidates for modified canal wall down mastoidectomy (MCWD) which contributes to a dry and spacious ear and the maintaining and improving hearing.

Objectives: To evaluate surgical outcomes for chronic otitis media underwent MCWD.

Methods: A clinical retrospective study was performed on 47 ears with chronic otitis media which has relatively limited attic lesions have the small, sclerotic and hypocellular mastoids according to the preoperative high-resolution CT scan of the temporal bone that underwent MCWD and 32 ears with typical canal wall down operation form January 2010 to January 2016.

Results: In the MCWD group, the mean preoperative air conduction (AC) threshold of 38.2?±?1.1?dB was lowered to 31.0?±?0.8?dB postoperatively (p?p?p?p?相似文献   

Analysis on the correlation between Eustachian tube function and outcomes of type I tympanoplasty for chronic suppurative otitis media

Abstract

Background: The potential influence of Eustachian tube dysfunction (ETD) on the efficacy of tympanoplasty is controversial.

Objective: This study aims to investigate the correlation between Eustachian tube function (ETF) and outcomes of type I tympanoplasty for chronic suppurative otitis media (CSOM).

Materials and Methods: 53 patients with CSOM and receiving type I tympanoplasty were divided into a dysfunction group (Eustachian tube score; ETS ≤ 5points) and a normal group (ETS > 5 points) according to their preoperative ETS. During the one-year follow-up, the ETS, hearing results, and eardrum condition of the patients were recorded and analyzed.

Results: The ETS improved significantly from 2.57 (±1.73SD) to 4.68 (±2.00SD), while the mean air–bone gap (ABG) decreased significantly from 20.94 (±9.04SD) dB to 16.43 (±9.06SD) dB in the dysfunction group (p?<?.05). The postoperative ABG showed no significant difference in the two groups. The healing rate of the tympanic membrane was 96.43% in the dysfunction group, and 100% in the normal group.

Conclusions and significance: The ETF was significantly improved after type I tympanoplasty for CSOM combined with ETD, and the postoperative efficacy was not adversely affected. The ETD may not influence the outcomes of type I tympanoplasty for CSOM.     

Review of a single surgeon’s stapedotomy cases performed with a nickel titanium prosthesis over a 14-year period

Abstract

Conclusion: Stapes surgery with a nickel titanium prosthesis is a safe and well-tolerated procedure that leads to a significant improvement in hearing outcomes.

Objective: To identify the efficacy and safety of stapedotomy procedures performed with a nickel titanium prosthesis for patients with otosclerosis.

Methods: A review of 431 unique stapedotomies performed over 14 years by a single surgeon at an academic tertiary care center yielded 312 cases with nickel titanium prosthesis that met inclusion criteria of otosclerosis diagnosis, initial surgery in operative ear, and presence of pre-operative and post-operative audiograms. Pure-tone averages (PTA) at baseline and 8 weeks after surgery were calculated over four frequencies; 0.5, 1, 2, and 4?kHz. Average air–bone gaps (ABG) were calculated from pre-operative and post-operative audiograms.

Results: Average pre-operative baseline PTA was 56.7?dB in the affected ear. Post-operative PTA was 30.1?dB, a 26.6?dB improvement. Initial average ABG was 29.7?dB, while post-operative ABG averaged 5.4?dB, a 24.2?dB improvement. Surgical success (closure of ABG within 10?dB) was achieved in 263 (84%) patients. Rate of surgical success was not correlated with age, gender, race, or affected ear. Complications included recurrent conductive hearing loss (14), progressive SNHL (4), and post-operative BPPV (3).     

The effect of inlay butterfly cartilage tympanoplasty technique on compliance

Conclusion: IBCT technique should be preferred owing to its high graft survival rate and ABG gain. While no significant difference was found in middle ear pressures between ears that underwent IBCT and normal ears, compliance values were found to be decreased in patients undergoing IBCT. However, the lack of correlation between ABG gain and compliance values indicated that compliance increase had no effect on post-operative ABG results. Objective: The aim of the present study was to compare tympanometric and audiological parameters in patients undergoing inlay butterfly cartilage tympanoplasty (IBCT) with their normal ears and to determine their difference with normal ear tympanometric parameters. Methods: Overall, 25 patients that underwent an operation between August 2010–May 2014 were included in the present study. In 13 of these patients, the ear that did not undergo operation was normal. 0.5, 1, 2, 4?kHz pure sound average values, tympanometric measurements and compliance values of normal and operated ears were compared. Results: The graft survival rate in patients was found to be 92%. Mean pre-operative air–bone gap (ABG) was 16.4?±?5.4 in patients, while mean post-operative ABG was 10.9?±?5.8, with a statistically significant difference (p?=?0.001) While there was no significant difference between operated and normal ears of patients in terms of middle ear pressure (0.441), compliance values were significantly higher in normal ears than those in operated ears (0.032). When post-operative ABG gain was compared with compliance values, no significant correlation was found between ABG gain and compliance measurements (r?=??0.025 and p?=?0.936).     

Endoscopic butterfly inlay myringoplasty: new technique extended perichondrium butterfly

Abstract

Background: Various graft materials and surgical methods are used in the treatment of tympanic membrane perforations.

Aims/Objectives: The aim of this study was to evaluate the operation method and graft success of extended perichondrial butterfly myringoplasty performed by an endoscopic method and the hearing gain of patients.

Material and Method: This was a retrospective study evaluating the hearing tests of 54 ears of 48 patients (28 male, 20 female) who underwent surgery between February 2017 and March 2019. Pure-tone audiometric results were analyzed preoperatively and six months postoperatively by recording the perforation size, the duration of surgery, and graft success.

Results: The graft success rate was 98.1% (53/54 ears). The perforations were most frequently located in the anterior quadrant and were small-sized. The mean preoperative air-bone gap (ABG) was 17.4?±?5.24?dB. The mean ABG was 9.2?±?2.13?dB 1 month postoperatively and 8.5?±?2.26?dB 6 months postoperatively (p?<?.005).

Conclusions: The endoscopic inlay extended perichondrial butterfly myringoplasty method is safe and doesn’t require tympanomeatal flap elevation. Moreover, it shortens hospitalization time, facilitates anatomical closure of the membrane, and sometimes closes perforations in the anterior part, which cannot be clearly evaluated after graft placement.     

Sealing of the round and oval window niches with triamcinolone-soaked fascia as salvage surgical therapy in sudden sensorineural hearing loss

Conclusions: Triamcinolone-soaked fascia seems to show better hearing improvement when added to tympanotomy for sudden idiopathic sensorineural hearing loss (SSHL), compared to fascia round window occlusion without triamcinolone.

Objectives: To analyse if adding triamcinolone to sealing the round and oval window niches with fascia results in improved audiological outcome for acute SNHL.

Methods: Fifty-three patients (27m:43?±?12 years, 26f:45?±?14 years) with acute SSHL ≥50dB over 3 frequencies, who failed primary therapy, underwent transcanal tympanotomy. Twenty-five patients (Group A;cortisone:14m, 11f:46?±?9 years) received sealing of the round and oval window with fascia soaked in triamcinolone (1ml; 40mg/ml) and 28 controls (Group B;no-cortisone:13m, 15f, 42?±?12 years) without triamcinolone. Frequency specific and pure tone average (PTA =500–1000–2000–3000Hz) results were compared between Group A and B pre- and postoperatively.

Results: In Group A the PTA improved by ≥10dB in 21/25(83%) cases; in Group B 18/28(63%). Group A showed a statistically significantly better improvement across all frequencies, while linear regression revealed a significant decrease of posttherapeutic PTA to 94.96% of the initial PTA (p?=?.037). The overall PTA improved by 24dB. Group A improved from 73dB to 41dB(-32dB) PTA, Group B improved from 76dB to 56dB PTA (-20dB) (p?p?相似文献   

Cartilage graft or fascia in tympanoplasty in patients with low middle ear risk index (anatomical and audological results)

The aim of this study was to compare anatomic and audiological results of cartilage graft with temporal fascia graft in type 1 tympanoplasty patients with low middle ear risk index (MERI). In this retrospective study, 63 patients that underwent type 1 tympanoplasty with chondroperichondrial island graft between July 2009 and November 2010 were compared with 45 patients in whom temporal muscle fascia was used. Patients in both groups had low MERI values varying between 1 and 3. Five and nine patients underwent masteidectomy in cartilage and fascia group, respectively. Mean duration of follow-up was 11.9 ± 3.7 (5–17) months. Mean value was calculated at pre-operative and post-operative hearing threshold 0.5, 1, 2, 4 kHz, and air bone gap (ABG) gain was compared in both cartilage and fascia groups. when pre-operative and post-operative ABG gain were compared, significant decrease was seen in ABG levels (p < 0.001). However, no significant difference was seen in ABG gain values (p = 0.608), which was 10.1 ± 7.00 dB in cartilage group and 10.8 ± 5.38 dB in fascia group. In both groups, age, sex, and the addition of mastoidectomy procedure had no significant effect on ABG gain and success. Cartilage is a graft material that may be preferred without concern about the effects on hearing results, especially, in patients with low MERI values. The addition of mastoidectomy had no impact on the outcome of operation and audiological results. However, further studies with larger case series may be carried out to further clarify the issue.     

Tympanoplasty – reporting hearing results and ‘hearing objective’

When reporting the results of tympanoplasty, the postoperative air–bone gap (ABG) presented in 10 dB bins, ABG closure and air conduction threshold gain are commonly reported indicators of tympanoplasty outcome. When tympanoplasty is performed, the reconstruction aims either to improve hearing threshold or to maintain satisfactory thresholds, that is, the surgical intention is either for ‘hearing gain’ or for ‘hearing preservation’. This review of the early results of tympanoplasty examines whether classifying surgery as either for hearing gain or for hearing preservation influences the reported results. Closure of the ABG to within 20 dB was achieved in 72–94% of cases, the average postoperative ABG was between 13.1 and 17.1 dB with the postoperative air conduction threshold being between 27.4 and 33.5 dB. These figures were similar for both hearing preservation and hearing gain procedures. However air conduction threshold gain was significantly greater for the ‘hearing gain’ group (17 dB versus 0 dB) and was reduced to 8 dB by combining the two groups. Overall, indicating whether surgery attempted hearing preservation or hearing gain did not significantly alter the parameters used for reporting tympanoplasty outcome.     

Prognostic roles of preoperative CT findings and air-bone gaps in type 1 tympanoplasty

Background: Although CT has been used widely, the role of preoperative CT findings including other factors in tympanoplasty has not been elucidated comprehensively.

Aims/objectives: To evaluate relationship of CT findings with other factors and audiological results in type 1 tympanoplasty.

Material and methods: A cohort of consecutive 175 patients with type 1 tympanoplasty was enrolled. Addition of mastoidectomy was based on the presence of soft tissue in antrum on CT. Postoperative air–bone gap (ABG) and reperforation rate were analyzed.

Results: Positive soft tissue in antrum on CT was found in 52 (29.7%) patients and showed larger preoperative ABG than the negative group. Successful ABG closure (≤20?dB) was obtained in 97% when preoperative ABG ≤20?dB, but it decreased as the preoperative ABG increased (83% with preoperative ABG of 21–30?dB, and 0% with preoperative ABG >30?dB). Postoperative reperforation rate was positively related to the preoperative ABG, but not the presence of soft tissue in the antrum, the size, or locations of preoperative perforations.

Conclusions and significance: Our findings showed that temporal bone CT was helpful in determining addition of mastoidectomy and the presence of soft tissue in the antrum was associated with large ABG.     

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

PurposeTo 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).Methods50 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.ResultsThere 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.ConclusionETBD can increase the success rate of cartilage tympanoplasty in patients with AdOM by enhancing the audiological outcome and quality of life.     

Closed tympanoplasty in cholesteatoma surgery: long-term (10 years) hearing results using cartilage ossiculoplasty

The aim of this retrospective study was to evaluate the long-term hearing results of using costal cartilage prostheses in ossicular chain reconstruction procedures in subjects operated on for a middle ear cholesteatoma with an intact canal wall tympanoplasty. Thirty-six patients (four with bilateral disease) followed up for 10 years who underwent an ossiculoplasty with a cartilage prostheses between January 1987 and December 1989 constituted the population studied. All the subjects underwent a staged intact canal wall tympanoplasty with mastoidectomy. Ossiculoplasty with total or partial chondroprosthesis was performed during the second stage. The long-term outcome was evaluated in terms of hearing according to the guidelines of the Committee on Hearing and Equilibrium (1995), and in terms of complications (anatomical and functional). In 18 patients a partial cartilage ossicular replacement prosthesis (PORP) was used, while in 22 a total cartilage ossicular replacement prosthesis (TORP) was used. In the PORP group the mean preoperative air–bone gap (ABG) was 22.4 dB hearing level (HL); before the second stage the ABG was 37.9 dB HL, at 2 years it was 12.1 dB HL, at 5 years 15.3 dB HL and at 10 years 15.8 dB HL. In the TORP group the mean preoperative ABG was 31.6 dB HL; before the second stage the ABG was 41.1 dB HL, at 2 years it was 14.4 dB HL, at 5 years 17 dB HL and at 10 years 18.5 dB HL. In both groups the number of cases with a postoperative ABG of < 20 dB HL remained stable (P > 0.05) over time. The failure rate was 17.5%, but only in 5% of cases was a functional revision needed. No cases of extrusion of the prostheses were encountered. The use of a chondroprosthesis is associated with functional results similar to those obtained by other authors. The efficacy of the prostheses remains stable over time and is associated with a very low rate of complications and failures. In this series no extrusion occurred and in no case did an infectious disease develop after cartilage transplantation. Received: 7 August 2000 / Accepted: 2 November 2000     

Bilateral same-day endoscopic tympanoplasty

PurposeAlthough bilateral same-day tympanoplasty is a faster and more comfortable procedure for patients, it is rarely performed due to its theoretical risks. The present study aims to evaluate the results of patients who underwent bilateral same-day endoscopic tympanoplasty.Materials and methodsIn this study, 26 patients and 52 ears were evaluated. Postoperative anatomic success rate, pre- and postoperative hearing test results, hearing gains and postoperative complications were recorded.ResultsPostoperative anatomic success rate was 92.3% (48/52). Audiological tests revealed the preoperative air-bone gap (ABG) as 19.1 ± 8.8 (7–35) dB and postoperative ABG as 9.8 ± 5.7 (5–25) dB. Postoperative ABG decreased significantly (p: <0.001) and 9.2 ± 4.6 (2−23) dB hearing gain was obtained. We did not observe any significant complications.ConclusionBilateral same-day endoscopic tympanoplasty is a feasible surgical procedure with good anatomic and functional outcomes, low complication rate and good postoperative patient comfort.
