Variant petrotympanic fissure as possible cause of an otologic complication during TMJ arthroscopy. A case report.

In this reported case, a variant petrotympanic fissure--opening at the height of the orifice of the Eustachian tube into the hypotympanon--was identified by high resolution computed tomography (CT) as the possible cause of a tympanic membrane perforation. Inner ear function was preserved by an otosclerotic stapes which prevented destruction of the labyrinth. The perforation was closed by a myringoplasty and was to be followed by a stapedectomy after six months to restore normal hearing. Surgeons performing temporomandibular joint arthroscopy should be aware that in a small percentage of patients a variant anatomy of the tympanic plate exists and, therefore, great care must be exercised in the manipulation of instruments near this structure. A preoperative high resolution CT with thin slices of the temporal bone might allow identification of these high risk patients.

A clinical comparison of the results of two different methods of closing tympanic membrane perforations.

A series of myringoplasties is presented and those cases that did not heal perfect are discussed. In order to evaluate whether some changes in the technique could further improve the results, another series incorporating these changes was operated after and the results are presented. Differences in healing and post-operative hearing between the two groups of patients are evaluated.

Iatrogenic epidermoid cyst of the parotid region following ear surgery.

Iatrogenic implantation of squamous epithelium may result in formation of an epidermoid cyst. These cysts have been described in various sites around the head and neck following otological procedures. A case of iatrogenic epidermal cyst in the parotid region following repeated myringoplasty is reported. The clinical features and differential diagnosis are discussed.

A five year follow up of incus transposition in relation to the first stage tympanoplasty technique.

This study was set up, prospectively, to determine factors affecting the long-term hearing results of patients undergoing incus transposition as a second stage in ossicular reconstruction, following a successful drumhead repair in non-cholesteatoma ears. Seventy-one patients were entered into the study over five years from 1980-1985, 66 were available to be studied throughout the five year follow-up period. Nine weeks post-operatively, 74 per cent of all patients has an air-bone gap of less than 15 dB (48/66). The type of first stage procedure had a significant effect on the hearing levels in the final five year assessment. The most successful sub-group were those patients who had a cortical mastoidectomy and silastic sheeting inserted in the first staging procedure. The air-bone gap, of less than 15 dB, was maintained in 71 per cent of this group (17/24). The sub-group who had a simple myringoplasty as the primary procedure had a good initial hearing level. By five years, however, only 30 per cent of the patients had maintained the air-bone gap of less than 30 dB (3/11).

Iatrogenic pulsatile tinnitus.

We present an unusual case of iatrogenic arteriovenous malformation following a myringoplasty and its treatment by embolization. Thorough examination and investigation of patients with pulsatile tinnitus is stressed. Angiography is essential to diagnose life-threatening and treatable lesions in the presence of normal otoscopy, audiologic assessment and enhanced computed tomography.

Unusual anterior course of the sigmoid sinus: report of a case and review of the literature.

The position and dimensions of the jugular bulb and the venous dural sinuses vary considerably. While the anatomical variations of the jugular bulb have been extensively reported in the literature, that of the sigmoid sinus have been reported only rarely. We report a case of unusual anterior course of the vertical segment of the sigmoid sinus which was encountered during an attempted myringoplasty. Anomalies of the jugular bulb in general are also described.

Cochlear implantation in the presence of chronic suppurative otitis media.

Nine patients are presented who underwent cochlear implantation in the presence of chronic suppurative otitis media. Four had a simple tympanic membrane perforation, four had a pre-existing mastoid cavity and one had cholesteatoma in the ear chosen for implantation. Patients with a simple perforation had a staged procedure with myringoplasty followed by cochlear implantation after an interval of three months. Patients with cholesteatoma or with an unstable mastoid cavity were also staged. A mastoidectomy or revision mastoidectomy was performed with obliteration of the middle ear and mastoid using a superiorly pedicled temporalis muscle flap and blind sac closure of the external meatal skin. After a further six months a second stage procedure was performed to confirm that the middle-ear cleft was healthy and to insert the implant. Patients presenting with a stable mastoid cavity underwent obliteration of the cavity and implantation of the electrode as a one-staged procedure. To date there have been no serious problems such as graft breakdown, recurrence of disease or implant extrusion, and all patients are performing well.

Temporalis fascia grafts shrink.

Temporalis fascia, placed as an underlay graft, is commonly used to repair tympanic membrane perforations. Graft failure, however, is a well recognized complication. Grafts are often allowed to dry out during the procedure and, therefore, are often positioned in a dry or partially dehydrated state and only become fully rehydrated after placement. This study looked at how the size of the temporalis fascia alters with its state of hydration. The size of 20 temporalis fascia grafts was measured when fresh, after flattening and allowing them to dry, and finally after rehydrating the grafts with 0.9 per cent saline solution. Significant shrinkage was demonstrated. It is therefore proposed that a cause of increased failure rates, particularly in anterior myringoplasties, is loss of underlay due to graft rehydration and shrinkage. Thus graft shrinkage should be considered when positioning the graft.

Paediatric tympanoplasty.

Much debate exists over the management of mucosal chronic suppurative otitis media in children, with the majority of it centred around the correct timing to perform either a myringoplasty (an operative repair of the tympanic membrane) or type I tympanoplasty (reconstruction of the tympanic membrane when there is an intact and mobile ossicular chain). Further discussion will use the term tympanoplasty to mean both of the above definitions. We present the findings of a recent survey of UK ENT consultants questioning their opinions on various management aspects of mucosal CSOM in the paediatric population. We also present an extensive review of the literature to provide us with published evidence in order to analyse the results of the questionnaire.

Surgical management of only hearing ears with positive indications.

Positive surgical indications for an only hearing ear were evaluated in order to improve patients' quality of life. Fifteen cases of surgery involving an only hearing ear over the past eight years were retrospectively reviewed. Of eight perforated chronic otitis media cases, seven underwent type one tympanoplasty and one underwent simple underlay myringoplasty regardless of otorrhoea at the time of surgery. Of six cholesteatoma cases, two received the canal wall up method and four received the canal wall down method. Ossiculoplasty was carefully performed in six cases. Hearing was improved in seven cases, whereas it remained unchanged in seven cases and deteriorated in one case. Of nine patients, two did not need a hearing aid after surgery. Five patients with severe combined hearing loss (>90 dB) were able to communicate with a hearing aid, alleviating their anxiety regarding hearing loss. Only hearing ears with chronic otitis media and cholesteatoma can be successfully treated by tympanoplasty with or without ossiculoplasty.

Local anaesthesia in middle ear surgery: survey of patients and surgeons.

The use of local anaesthesia for middle ear surgery is long established and has many advantages. However, it is only performed by a small number of UK otolaryngologists (20%). This lack of enthusiasm is due to concerns that patients may not tolerate the discomfort during the operation. Therefore, a survey was conducted on patients who had middle ear operations: stapedotomy, myringoplasty, ossiculoplasty and mastoidectomy. The intense sensation of noise during the operation (29.6% of patients) and anxiety (24%) were the most common discomforts, followed by dizziness (14.8%), backache (13.9%), claustrophobia (9.3%) and earache (1.9%). In spite of these discomforts, 89% of patients still preferred local anaesthesia to general anaesthesia for a similar procedure. The author suggests that good patient selection, pre-operative explanation and the use of appropriate sedation are the important factors for local anaesthesia ear procedures to be acceptable to patients.

Histology of the perforated tympanic membrane and its muco-epithelial junction.

A histological study was performed on total human tympanic membranes with a central perforation. The specimens originated from 30 consecutive and unselected operations in which a total myringectomy was performed prior to reconstruction by means of a tympanic allograft. Beside excessive thickening of the tympanic membrane in 73%, all membranes showed other histological abnormalities: inflammation (97%), excessive fibrosis (97%), tympanosclerosis (80%), hyperkeratosis (83%), rete riges (43%) and epithelial inclusions (6%). Histological localisation of the muco-epithelial junction showed a medial position in 30%, with extensive middle ear invasion by squamous epithelium in 7%. The surgeon performing myringoplasty should keep these findings in mind and he should closely examine the medial side of the perforated tympanic membrane in order to remove any ingrowing epithelium that otherwise would be trapped.

The results of chronic ear surgery in a training programme.

A retrospective study was undertaken of the results of surgery in a series of 782 patients with chronic otitis media. The recurrence rate of cholesteatoma was 20% of patients operated on by trainees and 12% operated on by the faculty. In ears with granulating otitis media, control of infection was achieved by trainees as often as by the faculty. The tympanic membrane healing rate of myringoplasty and tympanoplasty operations was 78% for trainees and 95% for the faculty (P < 0.001). Major surgical complications were relatively rare. It is concluded that the performance of trainees was fairly safe and better than expected, but some failures might have been prevented by closer supervision. Because of the decline in available patients for chronic ear surgery, it is suggested that the training programme should be restructured so that only those trainees who wish to pursue otological surgery as a career are trained in this field.

["Crown-cork tympanoplasty"--a method for complete reconstruction of the tympanic membrane].

The crowncorktympanoplasty is a technique for the total reconstruction of the tympanic membrane, recommended in cases of ear malformation, blunting-phenomena and total deficiency of the membrane caused by chronic otitis media. Autologous tragal composite graft is used for the myringoplasty. While the cartilage faces to the middle ear cavity, the overflapping perichondrium is layed on the bony meatal wall in the manner of a crowncork. 10 cases performed in the last two years are reported. In each one an intact tympanic membrane could be reached. In average, the ear bone gap could be reduced for 18.5, 17.5, 16.5 and 13.5 dB in the frequencies of 500, 1000, 2000 and 4000 Hz.

[Modern aspects of tympanoplasty. An overview].

The cholesteatoma should be removed with a canal wall down-technique in small mastoids. In patients with well or highly pneumatized temporal bones the reconstruction of the posterior canal wall is recommended after complete removal of the matrix. Myringoplasty is mainly performed using perichondrium. In highly damaged middle ears the cartilage palisade technique is indicated. The reconstruction of the ossicular chain performed using modern artificial materials.

Tympanic membrane perforation repair using AlloDerm.

BACKGROUND: Some patients lack quality autologous tissue for tympanic membrane (TM) grafting. AlloDerm (LifeCell Corp, The Woodlands, TX) is a preserved allograft that has been effective in nonotologic applications. OBJECTIVE: The goal of this study was to investigate AlloDerm in the repair of chronic TM perforations. METHODS: Ten adult chinchillas underwent a controlled, 2-stage procedure for creation and repair of bilateral TM perforations. Myringoplasties were performed. The control side (left) was repaired with autologous fascia; AlloDerm was used in all right ears. Grafts were assessed at 3 to 8 weeks. RESULTS: Complete TM perforation closure was noted in 9 of 10 (90%) control ears and 8 of 10 (80%) AlloDerm-treated ears. Fascia and AlloDerm integrated consistently with host tissues. No variables demonstrated statistical significance. CONCLUSIONS: AlloDerm appeared to be an ideal substitute for grafting of the TM. It was equally effective as fascia. Clinical trials in human beings appear warranted. Potential health care savings are discussed.

Inlay butterfly cartilage tympanoplasty (Eavey technique) modified for adults.

INTRODUCTION: Popular myringoplasty techniques include either an underlay or an onlay approach using tissues such as temporalis fascia or perichondrium as grafts. In 1998, Eavey described an inlay tympanoplasty technique in children using a cartilage graft which resembled butterfly wings. This technique was effective for closure of tympanic membrane perforations, while being more rapid for the surgeon and more comfortable for the patient. The aim of this study was to describe our results with modification of this technique in adults under local anesthesia. METHODS AND MATERIAL: Cartilage butterfly inlay tympanoplasty was carried out in 20 adult patients to close small-to-medium tympanic membrane perforations over a period of 11 months. Compared with the original description, 3 modifications are noted: (1) adult patients, (2) local anesthesia, and (3) no skin graft over the cartilage. We evaluated the success rate and postoperative hearing results. RESULTS: Two patients were not evaluated in terms of hearing gain because they had profound preoperative hearing loss. Fourteen patients had a postoperative 4 pure-tone average between 0 and 9 dB, 3 patients between 10 and 20 dB, and 1 patient greater than 20 dB. The graft "take rate" was 90% (18/20) at the end of the follow-up period (mean follow-up 7.25 months). Seventeen of 18 successful cases had cartilage grafts that were intact and dry at the last visit. CONCLUSIONS: The tympanoplasty technique described by Eavey is effective to close tympanic membrane perforation in adults as well as children. The technique modifications introduced here (abandonment of the skin graft and local anesthesia) reduced surgery time and postoperative morbidity. Postoperative results compared with those of the original technique were good.

Chronic tympanic membrane perforation: middle ear pressure and tubal function.

OBJECTIVE: To monitor the middle ear (ME) pressure continuously, day and night, in subjects with chronic central perforation (CCP) whose ears were temporarily sealed off from ambient air. MATERIAL AND METHODS: Twenty-three consecutive patients at our outpatient clinic, considered for myringoplasty, were studied. RESULTS: The measurements revealed slow pressure changes with a similar pattern in 21/23 subjects. The pattern could be divided into four periods: coupling; erect body position; sleep; and the period after getting up in the morning. The coupling period was characterized by an immediate fall in pressure in 19/23 subjects and the negative pressure trend continued during most of the time in the erect position. During sleep the ME pressure initially rose and then stabilized. When the subjects got up in the morning, the ME pressure declined again. CONCLUSION: The different pressure periods observed in this study confirm that ME pressure regulation is a dynamic process. There is clearly a difference in the ME pressure of ears with CCP compared to previous results obtained from continuous measurements in 20 healthy ears.
