Myringoplasty. A conventional and extended high-frequency, air- and bone-conduction audiometric study.

Comparison of the pre- and postoperative air- and bone-conduction thresholds in 22 subjects in whom successful myringoplasty was performed has been made in the conventional and extended high-frequency ranges. Air-conduction thresholds improved through 4 kHz, but were elevated postoperatively for the frequencies 6 through 18 kHz. Postoperative bone-conduction thresholds were elevated at 0.25 and 0.5 kHz, were lower by 2-8 dB for 1 through 3 kHz and not significantly altered in the extended high-frequency range of 8 through 16 kHz. The extended high-frequency air-conduction threshold loss following myringoplasty in this study is, therefore, due to changes in middle ear transmission and is not indicative of iatrogenic cochlear damage.

[Prognostic factors in pediatric myringoplasty. A review of 90 cases].

Although tympanic membrane perforations continue to be a significant source of otologic morbidity in the pediatric population, myringoplasty in children still elicits debate. The records of 76 patients under 18 who underwent 90 myringoplasties at the 12 de Octubre University Hospital (Madrid, Spain) over a recent 8-year period were reviewed. The overall short-term surgical success rate was 64.8%. The overall success rate evaluated at least one year after surgery was 58%. The audiological threshold improved in 68% per cent of successful cases. Surprisingly, females had lower graft take rates than males. The outcome of surgery was unrelated to age at operation, duration, mechanism, size, and location of the perforation, or condition of the opposite ear.

Myringoplasty: a simple procedure for out-patients.

The standard treatment of tympanic membrane perforation is myringoplasty. We describe a new myringoplasty technique requiring only a partial removal of skin on the ear drum remnant followed by lateral placing of fascia and free skin graft. The overall cure rate in our series is 97 per cent. The hearing gains for the overall cases are 13.9 dB (p < 0.001) for the AC, 13.6 dB (p < 0.001) for the air bone gap closure, 13.1 dB (p < 0.001) for the SRT and 4.2 per cent (p = 0.005) for the SDS. Minor complications are observed in only 14 per cent. Our technique is simple, effective and can be performed on an out-patient basis.

[Myringoplasty in chronic simple otitis media. Comparative analysis of underlay and overlay techniques].

Myringoplasty is a surgical procedure that has been routinely performed by otological surgeons for more than 40 years. Underlay and overlay are the most commonly used tympanoplastic techniques. A comparison was made of anatomic and functional results, and the year of intervention, for 97 myringoplasties, 54 using the underlay technique and 43 using the overlay technique. Selection of the overlay or underlay technique was guided by specific indications. Results were evaluated at least 1 year after surgery. No significant differences were found in anatomic success (88.8% for underlay and 97.6% for overlay). Favorable functional results (average gap of 0 to 20 dB for frequencies of 500, 1000, 2000, and 4000 Hz) were obtained in 88.4% of patients treated with the overlay technique and in 83% of those treated with the overlay technique, with no significant difference. We believe that the high percentage of good results was due to careful preoperative selection.

Myringoplasty with a single flap.

This article describes a myringoplasty technique that involves the use of a single flap of meatal skin and tympanic membrane epithelium. The procedure was performed on 148 patients. A success rate of 90.5% was achieved, with early epithelialization of the grafted tympanic membrane and the avoidance of various problems encountered in the performance of other forms of myringoplasty.

[Transmeatal direct myringoplasty].

A surgical method of transmeatal direct myringoplasty (TDM) was performed in 30 patients. Out of those, 21 patients were previously treated for chronic otitis media, 4 patients were with dry perforations of neomembrane following myringoplasty, and 5 patients were with blasttraumatic ruptures of the eardrum. Fascia of the temporal muscle was used in the defect reconstruction. Graft healing and closure of the eardrum defect were observed in all patients 3 months after the surgery. Postoperative improvement of hearing in an interval of 15-20 dB was found in 21 patients. Milder sensorineural hearing damage was found in 1 patient, while in the others the hearing was on the preoperative level. Simplicity of the method, minimal surgical procedure and favorable postoperative results were the reason why the authors recommended TDM as the method of choice in the reconstruction of the eardrum defects caused by an inflammation or blasttraumatic damages of the eardrum.

[Report of myringoplasty with interlay method in 53 ears perforation of tympani].

OBJECTIVE: To probe into an eutherapeutic method for the healing tympanic membrane aperture. METHOD: Fifty-three cases of tympamic membrane aperture were treated with myringoplasty of interlay method. The results were compared with that of underlay method of 168 ears in same period. RESULT: The rate of closure of perforation of tympani was 96.2% in interlay method group and 85.7% in underlay method. The hearing recovery of interlay method group was better than underlay method group. Function of Eustachian tube kept good condition in interlay method group. There was no blunting of anterior tympanomeatal angle in the interlay group. CONCLUSION: The interlay method of myringoplasty is an ideal method for healing perforation of tympani.

[Myringoplasty. A prospective study of 238 cases].

It has been made a review of 238 myringoplasties done in the last three years (1988-90) at the Santa Creu i Sant Pau Hospital. In this work are only contemplated the plain myringoplasties. Tympanoplasties because cholesteatoma and ossiculoplasties are excluded. Some characteristics are studied: age, sex, ear state, kind of perforation, ossicular chain state and others. Anatomical and functional results are analyzed as also the relationship between the type of perforation with the audiometric loose and anatomic success.

[Myringoplasty].

In the course of eight years the authors made several types of myringoplasties. In 97% a fascial graft was used with a premyringeal or retromyringeal approach. In small central perforations stepp plasty proved useful, in major defects a combination of stepp plasty and placement of the graft beneath the tympanomeatal lobe or beneath the skin of the auditory meatus resp. Anatomical healing was achieved in a total of 90%. Eight per cent of the patients were re-operated with satisfactory results. After simple myringoplasties the auditory gain was 15-20 dB in 90%, after reconstruction of the entire conduction system hearing improved markedly in 64%. Hearing did not deteriorate after operation in any of the patients.

Myringoplasty: long-term followup.

A long-term follow-up was performed of 540 myringoplasties that were considered to be successful 3 months after operation. The ears were observed to 12 years, and it was found that 70.8% of the eardrums were intact, fully epithelialized, and without retraction. In 22.4% success was only partial, because there was a small reperforation, a slight retraction of the eardrum, or an epithelial defect. In 7.6% of the eardrums deterioration occurred over the years, for the above three reasons, to a degree that turned an initial successful outcome of the operation into a failure. Of the various factors that characterized and accompanied the initial perforation before the operation, or the various operative technical aspects, none was found to influence the late outcome of myringoplasty. An exception was the anterior perforation, in which prognosis was less favorable than in any other perforation. During our continuous follow-up about a fourth of the reperforations perforated spontaneously and silently, some doing so several times over and over. This particular phenomenon could bear on the etiology of the group of tympanic membrane perforations that has no obvious inflammatory or traumatic history.

Myringoplasty in children.

The fact that myringoplasty in children is relatively less satisfactory than in adults, motivated us to perform a retrospective study, gathering material on 53 children aged 4-12 years who underwent 68 operations to determine if any pre-operative or intra-operative parameters might predict the outcome of surgery. Results show that the overall success rate of Type I tympanoplasty was 78%, and that the majority of failures occurred later in the follow-up course. Furthermore, age and technique of operations played the most important roles in the results. The status of the non-operated ear did not influence the surgical outcome. Finally, revision myringoplasty was equally as successful as the primary operations.

[Personal experience and results in the treatment of hearing loss with myringoplasty].

Within the period of eight years (1973-1981) at the Clinic for ORL Diseases of the Military Medical Academy 150 myringoplasties were performed. The authors have presented the method, choice of grafts for reconstruction, functional success and immediate complications. Improved hearing was achieved in 89,34% of patients while hearing impairment was found in 10,66% of patients. The authors consider that myringoplasty, together with good microsurgical technique choice of grafts and correct indications, presents one of most successful otological operations.

Experimental myringoplasty.

Different materials were compared as implants in performing a myringoplasty on rats immediately after making a total perforation, (autologous fascia, homologous tympanic membrane, homologous collagen, heterologous collagen, heterologous amnion and proplast). As a reference one group of rats had no myringoplasty done after perforating their drums. The animals were examined regularly, then killed after 40 and 64 weeks. Macroscopically and microscopically proplast and homologous collagen were very inferior to homograft tympanic membrane and autologous fascia. The best results were obtained both macroscopically and histologically with heterologous collagen and heterologous amnion.

Myringoplasty: the lateral graft technique with fascia.

Grafting the tympanic membrane can be successfully accomplished by a number of techniques. The otologic literature is replete with descriptions of methods, materials, and results in myringoplasty. It is generally agreed that whatever method and materials are used to graft the tympanic membrane, the graft take-rate should be at least 90%. The key to obtaining a 90% take rate is not the technique employed, but how well the surgeon performs the technique. This article describes the lateral graft technique with fascia. This is the author's preferred myringoplasty procedure. When properly implicated, the lateral graft technique provides reproducible results in any pathologic condition. Excellent hearing and morphologic results can be obtained with few complications.

Myringoplasty in the outpatient clinic.

In 1990, the authors first started performing myringoplasty with temporal fascia homografts and fibrin glue in the outpatient clinic with consequent reduction in expenditure, time and patient physical stress. Of primary consideration in homogeneous transplantation is the possibility of infection by HIV or other pathogens from donors. The fascial grafts were submitted to treatment with 99% ethyl alcohol and pasteurization resulting in the inactivation of pathogenic viruses. This paper discusses methods, eardrum perforation closing rates, hearing improvement and future application of myringoplasty.

Findings in revision myringoplasty.

Findings in 38 revision myringoplasty operations were studied. Fascial grafts were used in all operations. The majority of immediate failures after primary procedures were found to be consequences of technical faults, i.e. poor anterior adaptation of the graft. Most of the late re-perforations were caused by atrophy of the graft without infection. The success rate for revision myringoplasty did not differ significantly from that for primary operations. It was concluded that better surgical techniques and better graft materials should be developed.

Myringoplasty: is molded collagen xenograft a valid alternative for fresh temporalis fascia?

Seventy four simple myringoplasties, 53 with xenograft and 21 with fresh temporalis fascia were reviewed. Closure rate for all cases was 90.5%. There were 3 surgical failures in xenografts and none in the fascia graft. Fifty two myringoplasties, 37 using xenograft and 15 using fascia graft, had a mean follow-up of 20 months and late perforations were seen in 4 of these cases. Three of the late reperforations occurred in xenografts, one in the fascia graft. Postoperative air bone gap was within 15 dB in 83.3% of the xenografts and in 66.7% of the fascia grafts. Recurring bouts of granular myringitis after 6 months were seen in 4 xenografts and in one fascia graft. Based on these results xenograft can be considered as an alternative for fresh fascia in easy to reach perforations operated "in speculo" when there is no need for an external incision.
