[Survey of 80 myringoplasty].

We report a retrospective study about 80 myringoplasties performed on 75 patients. The single occlusive myringoplasty technique was undergone in 33.7 percent of cases, while the tympanomeatal flap procedure was used in 66,2 percent. The grafted material was temporal muscle fascia (63.7%) or tragus perichondrium (36.2%). In 30 percent of instances some retouches were achieved on the ossicular chain. The anatomic success rate accounted for 67.5% and a good functional issues for 59.7% of cases.

[Extrameatal myringoplasty in the treatment of tympanic membrane perforations].

The clinical analysis of the patients after tympanic membrane reconstruction with the temporal muscle fascia has been conducted. The total number of 145 patients, operated at the Otosurgery Department Medical University of Lodz, was divided into 2 Groups. Group 1 (n = 75) patients with chronic otitis media (central perforation and mobile ossicular chain). The preoperative mean conductive hearing deficit of 20 dB was observed in all evaluated patients. After surgery a satisfactory hearing improvement was observed in 90% of the patients. Group 2 (n = 70) patients with the reconstructed postero-superior part of the tympanic membrance and if necessary external auditory canal wall reconstruction. The mean conductive hearing deficit of up to 30 dB was observed before the surgery. Postoperatively in 75% of patients the hearing improvement was observed as well as the satisfactory healing of fascia implant. The postoperative evaluation indicates a better hearing improvement after the myringoplasties with the prefascial lamina than in the myringoplasties performed in the traditional ways.

Heterograft Myringoplasty.

Heterograft myringoplasty on dogs was performed. Serosa of the cecum of the calf was used in eight middle ears and cadaver tympanic membrane of the calf with the malleus attached in four. All canine eardrums were healed 10 to 12 weeks postoperatively. The heterografts were then unidentifiable. In only two middle ears did a mild inflammatory reaction occur with serosa grafts, but in three of the four middle ears with cadaver eardrum grafts, severe inflammation and scarring appeared. The attached denatured calf malleus was being remodeled into a canine ossicle by new bone deposits. The results with calf serosa graft indicate that tolerance and survival might be expected using it in the human ear. However, the experiences with the calf cadaver tympanic membrane suggest a need for great caution in expanding the present information to surgical use in the human.

Homograft tympanic membrane myringoplasty.

During a six-year period, homograft tympanic membranes have been used successfully for myringoplasty or tympanoplasty in 85% of 175 cases. This percentage is not as high as might be expected with fascia, and the homografts have not been as dependable in the wet, draining ear. However, the results do show that the homograft is an acceptable grafting material. The eardrums are not suggested as substitutes for fascia, but should be available for difficult cases. Their use is indicated in large or total defects to restore the natural anatomical conical shape of the eardrum, particularly in congenital atresia. The prime indication for their use is a missing malleus, and the malleus handle can be included within the transplant. The eardrum's rigid properties and the possibility of inclusion of ossicles make the homografts valuable in reconstruction of the old mastoid cavity.

Myringoplasty as an office procedure: a new technique.

An office technique uses preserved dry temporalis fascia homograft to close eardrum perforations smaller than subtotal. A follow-up on 36 patients who under-went this technique revealed a 64% success rate and 11% partial success rate. If the patients whose eardrum remnants were atrophic or scarred with or without calcareous deposits (11 cases) were excluded, the success rate becomes 76% and the partial success rate 8%. This technique is therefore recommended for patients whose eardrum remnants are healthy because it is simple and it saves time and money. In case of failure, the situation does not become worse and a regular myringoplasty may then be performed.

Failures in myringoplasty.

We analyzed those failures occurring in 417 myringoplasties. Forty-four drum re-perforations were found (10.6%), half of which occurred immediately after operation. Causes of these early failures included necrosis in the middle of the graft without infection (10 ears) and blunting of the anterior margins of the graft (7 ears). Infection was the most common cause of re-perforations in the later failures. Re-perforations also occurred more frequently when larger perforations were closed in contrast to repair of small ones. We found that other pre-operative factors ("dry" or "wet" ear, site of the perforation) or grafting technique ("underlay" or "overlay") did not affect the graft take-rate. Adhesive eardrums were found in 23 ears (5.5%). These were more common when ears were infected pre-operatively, when middle ear mucosa was removed during the primary operation, or when squamous epithelium was present on the tympanic mucosa. Lateralization of the grafted eardrum was found in two cases (0.5%), both of which had been operated on using the sandwich technique.

Myringoplasty for anterior and subtotal perforations using KTP-532 laser.

A retrospective study was performed on patients who underwent myringoplasty for either anterior or subtotal perforations over an 8-year period (from 1994 till 2004). We used the KTP-laser assisted anterior anchoring technique combining with anterior "pull-back" method. Patients' ages ranged from 6-62 years (median 36.5). The mean follow-up period was 2.8 years (minimum 6 months). The audiological results were analysed with the "Pytel software", which was developed in our department. As for the procedure, the drum remnant was freed from the malleus handle with the use of the laser and elevated out of it's sulcus anterior-superiorly. Large fascia graft was fashioned with a split of 4-5 mm in the middle of one edge. The graft was placed using the underlay technique medial to the handle of the malleus. A pull-back tunnel was created at the border of the anterior quadrants to further facilitate the survival of the graft. In this series the graft taking rate was 100%. Reperforation due to an undersized fascia was observed in one case. Post-operative audiological results indicated no bone conduction threshold elevation in any frequencies. Using the laser, cochlear trauma can be prevented, double fixation of the drum prevents lateralisation and blunting. Wide canalplasty makes both the approach and the follow-up very easy. Thorough soft tissue and bone work is advantageous from the fascia taking rate point of view.

Transtympanic myringoplasty in children.

Our experience with myringoplasty by the transtympanic "push through' technique in paediatric patients is described. We have used this method in 40 children utilizing autologous temporalis fascia as the graft material. The procedures were all performed as day cases under general anaesthesia. The overall success rate for perforation closure was 77.5% at 6 months which is comparable to conventional methods. We conclude that the "push-through' technique is a safe, simple, reliable and cost-effective procedure that can be performed as a day case in paediatric patients. It avoids the necessity for pressure bandaging or formal ear packing. To our knowledge this is the first paper evaluating this technique in children.

Paediatric myringoplasty in India.

In comparison to chronic non-suppurative otitis media, the incidence of chronic suppurative otitis media is no less in developing countries. This is due to lack of consciousness, low socioeconomic condition, and increased susceptibility to upper respiratory tract infection. Thirty-two ears of 20 patients between the ages of 5 and 12 years are included in this study who underwent myringoplasty, and were followed up for 3 months to 1 year postoperatively. Successful take of the graft was 60% in patients of 5 to 8 year age group, and 72.7% in 9 to 12 year age group. Postoperative air conduction was elevated up to 10 dB level in all the successful ears. In paediatric patients, the tympanic membrane perforation should be repaired to reduce the enormous degree of morbidity, and economic and social disability which afflict so many hundred thousands of people.

Simple in-office closure of small intractable tympanic membrane perforations after myringoplasty.

Perforations produced following myringoplasty are very difficult to close by ordinary cautery or patching even if they are small. Therefore we decided to close these intractable perforations with a skin graft from the cartilaginous ear canal. Our method is an in-office operation under local anesthesia. After the removal of epithelium from around the perforation a skin graft was placed by the over-lay method. A total of 11 patients were treated, of which 81.8% (9/11) demonstrated successful closure in the initial surgery and two re-perforations were successfully closed by a second and third operation, respectively. The technique used in this surgery is relatively easy and appropriate for in-office operations. The method's advantages include decreased invasiveness with minimal anesthesia and no requirement for ear canal packing or fixatives, and cosmetic benefit. This method also can be applied to perforations caused by chronic otitis media, traumatic perforations, and perforations after inserting tubes.

Healing and hearing in uncomplicated myringoplasty.

In closing an uncomplicated central drum defect the technique known as an 'underlay' is widely used. This method has certain advantages and yields good results as far as both healing and hearing are concerned. In an attempt further to improve results the authors give an account of a series of myringoplasties and specifically discuss the unsuccessful cases. By a slight alteration in the operative technique used in the series presented, the authors believe that some failures can be avoided.

Myringoplasty with three meatal flaps.

A preliminary report on a technique of myringoplasty is presented with the idea of minimizing graft rejection, and to combat anterior blunting and lateralization of the graft. The grafts were generally stable and mobile. Out of 200 cases there was only a 2 per cent rate of graft rejection, with no evidence of anterior blunting or lateralization. The hearing improved considerably. The technique is simple and relatively quick.

An evaluation of myringoplasty in war injured people.

Perforation of the tympanic membrane is a common war injury, especially after explosions. Such perforations will normally heal spontaneously under favourable conditions. A small number in whom the defect persists will benefit from closure by myringoplasty. Thirty-four such cases underwent operative repair and were compared with an equal number due to other causes.

Myringoplasty.

There is marked diversity in the reported success rates for achieving an intact tympanic membrane following myringoplasty. Controversy exists about the factors thought to influence surgical outcome. Both of these facts have important implications for obtaining informed consent prior to surgery. This study reviews the factors thought to determine the likelihood of achieving complete closure of the tympanic membrane following surgical closure.

Myringoplasty.

Myringoplasty is a deceptively difficult procedure in which surgical finesse and experience dictate success in terms of hearing improvement as well as closure rate. In essence, it is the complete removal of epidermal ingrowth followed by the placement of a non-epithelialized graft on the medial surface of the tympanic membrane which has withstood the test of time.

The predictive value of eustachian tube function (measured with sonotubometry) in the successful outcome of myringoplasty.

Sonotubometry, as a technique for assessing Eustachian tube function, does not rely on an intact tympanic membrane. This device has been used to study 25 patients having myringoplasty who all had preoperative testing and post-operative testing at 4 months. The overall success rate for grafting was 76%. In those who had normal preoperative tubal function the success rate was 86%, as opposed to 67% in those whose preoperative tubal function was poor. This difference was not statistically significant. In all those patients where poor preoperative function ended with successful grafting, post-operative tubal function reverted to normal. Other factors also taken into account, such as the patient's age, size of the perforation and the operative difficulty, had no bearing on the outcome of surgery.
