Otosclerosis surgery: reassessment of its value in 1978.

Today, surgical correction is the treatment of choice for the hearing loss associated with footplate otosclerosis. Experience with stapes surgery reveals this to be functionally and economically superior to the long-term use of hearing aids. There is, however, a predictable rate of surgical complications. Sensorineural hearing loss, dizziness and/or facial nerve palsy have an immense social and economic impact upon the patient, the family and the surgeon. Otosclerosis surgery will be presented in the perspective of benefits, untoward results, and alternate forms of treatment. A cost analysis of the foregoing will shed light on the future of otosclerosis surgery.

Failures in surgery for stapedial otosclerosis.

The causes for failure in surgery for stapedial otosclerosis are many. Most of these occur in the early postoperative period. Failures occurring later are due to either a breakdown of the reconstructed transformer system or to a labyrinthitis due to failure of the vestibular seal. The role of cochlear otospongiosis in producing late failures has not been sufficiently emphasized. This clinical review of 105 surgical failures examined consecutively during the years of 1975 through 1979 will demonstrate the importance of cochlear otospongiosis in this consideration. The fate of the unoperated-on ear in unilateral surgical failures will be demonstrated. Control of the progressive sensorineural hearing loss in these instances can be gained by the use of sodium fluoride therapy.

Cooling induces a decrease in middle ear compliance.

The effects of cooling rats from 37 degrees C to 27 degrees C and rewarming to 37 degrees C on the conductive mechanism of the middle ear was studied by means of acoustic impedance measurements. Cooling reduced middle ear compliance reversibly, without an effect on external canal volume and middle ear pressure. These results provide evidence for an increase in the stiffness of the tympanic membrane and/or of the ossicular chain and/or a decrease in stapes mobility. Thus a small part of the decrease in the magnitude of otoacoustic emissions during cooling is due to an effect on the conductive mechanism of the middle ear.

Management and prevention of primary perilymph fistula in otosclerosis surgery.

Management of 10 cases of primary perilymph fistula is described. The modified technique of stapedectomy described in this article, seems to prevent primary perilymph fistula; time will tell if it will prevent secondary fistula. The hearing gain obtained with this technique is slightly inferior to the gain obtained with Gelfoam-wire prosthesis, but most significant is the fact that discrimination score is excellent in all cases. The author is convinced that the extra time and dexterity required to perform this procedure are well justified by the safety provided and the results obtained.

[Otosclerosis in children (author's transl.)].

11 children (13 ears) have been operated upon for otosclerosis. In ten cases the stapes footplate was found totally fixed, with histological verification of the diagnosis of otosclerosis. Conservative surgery of the oval window was possible in only four cases. All other patients required total removal of staples or footplate. Findings indicate that clinical otosclerosis occurring in childhood results in an otosclerotic process in the oval window region with total fixation of the footplate. Thus, correction usually requires removal of at least the entire footplate.

[The choice of the stapes surgical style in treatments of the otosclerosis].

OBJECTIVE: To investigate the effects of the stapes surgery on treatment of the otosclerosis to find out the more suitable surgical style. METHOD: 71 cases including 31 cases with stapes lifting surgery, 34 cases with partial stapcdectomy, 6 cases with total stapedectomy were summed. RESULT: Both the stapes lifting surgery and partial stapedectomy have steady effects on hearing level for a short or long time. CONCLUSION: The stapes lifting surgery should be adopted as the first surgical style for it is easier and the vestibular reaction is slighter. It will not affect the following surgical process even the two crura are broken.

[Long-term results of stapedectomy and stapedotomy].

We have followed up 91 patients for 3 or more years after stapes surgery for otosclerosis, 59 by stapedectomy and 32 by stapedotomy. The surgical technique was chosen randomly. Both surgical techniques achieved significant hearing improvement, but in the higher frequencies (3 kHz) the results of stapedotomy are better and more stable than those after stapedectomy. Surgical revision was necessary in 5 patients--1 after stapedotomy, 4 after stapedectomy.

Stapedectomy--past and present.

Surgical technics for bypassing ankylosis of the stapes in the management of otosclerosis gradually evolved; modifications were prompted by problems which were revealed by the ongoing audits carried out by earlier surgeons. Auditing of performance must remain an integral part of any otologist's work. The natural history of otosclerosis should be taken into account so that a patient may be fully informed of treatment alternatives available. Stapedectomy will remain a most effective operation which can be recommended with confidence, provided the surgeon has acquired the skill to perform it properly. It is now accepted that many ear, nose and throat surgeons are neither physically nor temperamentally capable of this task and should not perform stapedectomy.

[Cochlear damage caused by middle ear surgeries].

A prospective study was set up to study the reaction of the cochlea after the trauma of middle-ear surgery. For this purpose, the bone conduction of 50 patients was tested every day, beginning on the first post-operative day. To collect information on possible damaging mechanisms, three surgical techniques were studied: Stapes surgery with the opening of the inner ear; mastoidectomy with drill-generated noise; tympanoplasty with manipulations at the stapes. The comparison of the bone conduction thresholds with audiometry results after completed healing of the ear, disclosed that even under the ear-packing, bone conduction can give reliable information on cochlea function, if a 10-15 dB variance due to methodological causes is taken into account. Excessive drilling may result in a temporary threshold shift, which has already resolved at the time of unpacking the ear. No signs of hydraulic damage after manipulation at the stapes could be discovered.
