[Myringoplasty using formaldehyde formed fascia (Perkins' foot) in 188 cases: anatomical and functional results at 5 years].

Herein we explain the experiences we have had, in the ORL department of the HCU of Valencia, al along a period of seven years, by using the formaldehyde formed fascia graft, exposing the anatomical and functional results obtained after a minimum pursuit of five years on a sequence of 188 myringoplasties. With such method we got to close the tympanic membrane, and that they remain entire after five years, on the 72.87% of the cases, getting improvement of audition determined by a reduction of the air-bone gap greater than 15 dB, in the 62.77% of the cases. Such results are obtained with a very slight number of complications. This all makes us to consider this technique as the proper one in cases where perforation is greater than 50% of tympanic membrane.

[The butterfly-like type of myringoplasty. Our experience].

The attempts for closing tympanic perforations has been a matter of concern between the otologists since past times. BANZER, in 1640, tried to seal them with pork bladder; YEARSLEY, in 1850, was the first to use a fragment of cotton wool to patch them up; BERTHOLD, in 1878, used skin grafts; and BLAKE, in 1887, did the same with papier patches. From 1950 onwards, owing to the spreading of optical devices, the utilization of several materials become generalized. Although independently of the followed technique high rates of closures were recorded, it seems advisable to stablish a procedure joining good results and the easiness of placement of the piece and, specially, to avoid the general anesthesia. In our Department the butterfly-like method of myringoplasties is practised in certain cases. The procedure is based in that of STROUD. The results are not better as those gained through classics but it is worth because of the advantages of application and the accuracy of placement.

Success and pitfalls in myringoplasty: follow-up study of 404 cases.

Results of 404 primary myringoplasty operations were critically analyzed. Patients who underwent tympanic membrane repair as the only procedure were included. In all cases, temporal muscle fascia was used as graft material. Mean follow-up period was 5.5 years. Overall success rate was found to be 88 percent. Welding injuries did not heal as well as other traumatic perforations or perforations caused by otitis media. Age of the patient, size or site of perforation, or surgical technique (underlay or overlay) did not affect success rate. Twenty-five percent of the failures were considered to be attributable to eustachian tube insufficiency. One percent (5 cases) failed as a result of chronic mastoiditis overlooked by the surgeon. Postoperative cholesteatoma developed in three ears (0.7%). Postoperative air-bone gap within 10 dB was achieved in 61 percent and within 20 dB in 87 percent of patients. In 11 of the audiologic failures, the cause of persistent conductive hearing loss was found to be fixation or erosion of the ossicles overlooked by the surgeon. The most decisive factor influencing results appeared to be the surgeon's experience.

[Myringoplasty: onlay vs. underlay. Review of 460 cases].

A retrospective review was made of 460 myringoplasties performed in our department from 1984 to 1990. In 80%, the perforation closed successfully. There were no differences in site, size, cause, or previous operations. Results were statistically better with the onlay technique than with the underlay technique, particularly in large perforations. Poorer results were obtained in younger patients, a difference that almost reached statistical significance. Hearing improved in 64% of patients with closed perforations and hearing deteriorated in 29% (2.1% complete hearing loss).

Homograft myringoplasty-controlled button technique: a preliminary report.

The successful outcome of homograft myringoplasty in small and medium perforation of the tympanic membrane was only 44.12 per cent. A better result was obtained in the small perforations (59.10%) compared with the medium ones (16.77%). We conclude that the procedure should be appropriate for repairing the incomplete healing of the tympanic membrane following standard tympanoplasty and removal of the tympanostomy tube. Furthermore this procedure is simple, safe, cost-effective and can be done in the out-patient department.

[Hammock myringoplasty (technique, results)].

Since 1985, we have been using the so-called "hammock" technique in myringoplasty through the retro-auricular approach, with a temporal fascia graft positioned under what is left of the tympanum. The main feature of this technique lies in the creation of a cephaled tympano-meatal flap by a partial disinsertion of 4 to 5 millimetres of the cephalad part of the Gerlach annular labrurm, taking care to leave 2 millimetres of the labrum attached above the junction of the ephalad wall and the lower wall of the external auditory canal (anterior lower anchoring point). At the end of the operation, the graft is fixed both to the cephalad and to the caudad wall of the bony-external auditory canal like a hammock. This technique makes it possible to verify systematically the tympanic opening of the Eustachian tube. The use of biological glue is desirable, but not essential. The graft is stable enough for the implantation of Politzer's manoeuvre as from the seventh day and for Valsalva's manoeuvre from then on. Out of 213 operation, including all kinds of pathologies, 98% of good results were obtained as from the end of the first month, and 94.6% after three months.

[Annular wedge tympanoplasty: a variation of overlay myringoplasty].

Myringoplasty has been increasingly refined in recent years and today the most frequently employed are the "overlay", the "underlay" and the "interlay". Of these the overlay technique appears to best guarantee graft stability. However, with this technique there is the risk of blunting and neotympanum lateralization which can compromise functional recovery. To obviate these drawbacks, the authors propose a modification of the classical overlay technique. This modification consists of detachment of the anterior portion of the Gerlach annulus and the adjacent protympanum mucosa in order to insert the graft between the bony and fibrous portions of the annulus. This technique is defined as the "Annular Wedge Tympanoplasty" (AWT). From January 1993 to July 1994 a total of 74 tympanoplasties were performed using the AWT technique to reconstruct the tympanic membrane. In 71 (96%) of these, the opening closed completely. As regards incomplete healing, 2 cases showed signs of blunting, 3 showed posterior lateralization and 1 full lateralization with a reduction in the hearing level recovery. The work is not conclusive although it does present a technique which is easy to perform and which provides good functional recovery.

[The dynamics of two-layer graft acoustic properties at different times after myringoplasty].

A two-year follow-up tympanometric results have been analysed for 40 patients subjected to myringoplasty. Ultrathin allocartilage was used as one of the transplant components. The static compliance of the neotympanic membrane seemed to change in a wide range, but the changes did not affect hearing. The formation of an adequate neotympanic membrane takes place by the end of the second year after the operation.

Repair of tympanic membrane perforations using hyaluronic acid: an alternative to myringoplasty.

Fifteen dry, small or medium-sized tympanic membrane perforations were treated by local application of 1 per cent hyaluronic acid after excision of the perforation rim. The duration of the perforations ranged from two months to ten years. Fourteen of the perforations were covered within 15 +/- 7.4 (S.D.) days and 5 +/- 2.4 (S.D.) applications were needed to achieve closure. Hyaluronic acid treatment of dry tympanic membrane perforations not exceeding one quadrant seems to be an alternative to surgical myringoplasty.

[Medial or lateral placement of the graft in myringoplasty comparative studies of both operation techniques using electronic data processing (author's transl)].

After medial placement of the graft in myringoplasty the remaining air-bone gap within the speech range is on an average approximately 10,- dB. This remaining air-bone gap is, according to secured statistics, on an average approximately 10 dB lower than in a lateral placement of the graft. The bone conduction does usually not change in either operation method. The additional support of meatal skin graft on the underlayed fascia does not have any influence on the audiologic finding. The percentage of the reperforations is in type I with a rate of 18% rather high; both operation methods do not significantly differ.
