Lasers in surgery for chronic ear disease.

This article describes specific situations in which the laser has been found to be useful in surgery for chronic ear disease. In the opinion of the authors, the most important application is the atraumatic removal of cholesteatoma from a mobile stapes. Additional uses include precise and hemostatic removal of diseased tissue (polyps, granulations, adhesions) and manipulations upon an intact ossicular chain without induction of vibrational trauma. Potential complications such as facial nerve and inner ear injury are considered.

[Cochlear implant in inner ear abnormalities and footplate malformation].

BACKGROUND: Malformations of the cochlea can cause deafness and otogenic meningitis. Cochlear implantation in children with such malformations, which are sometimes quite complex, require special attention before, during and after surgery. PATIENT: The concept developed for these patients at Hannover Medical School is illustrated in a patient with severe bilateral inner ear malformation and bilateral stapes defect. Implantation of a cochlear implant was performed in this 2-year-old girl. A large endostal sack originating from the inner ear, which had caused meningitis twice, was observed in the right middle ear. Both ears had to be obliterated to prevent recurrent meningitis. RESULTS: The child had no post-operative problems and the initial rehabilitation efforts have been successful. The immediate and differentiated reactions to stimulation are very encouraging. This article briefly summaries all diagnostic and therapeutic procedures established over the last three years at Hannover Medical School in cases of implantation into a malformated cochlea. In particular, we describe perioperative radiology (CT scans, MRI and plain radiographs), facial nerve monitoring and intraoperative screening for "hearing sensations", details of surgical technique, and possible postoperative complications. CONCLUSIONS: Based on experience with 13 of these cases, we discuss the different aspects of implantation into a malformated cochlea. Given certain preconditions implantation into a malformated cochlea may be recommended.

A confidential comparative audit of stapedectomies: results of the Royal College of Surgeons of England Comparative Audit of ENT surgery 1994.

This paper presents the results of a national confidential comparative audit of stapedectomy: 185 operations by 28 consultants over a two-year period were retrospectively analysed. This included 10 revision procedures. Small fenestra stapedectomies accounted for 63 per cent of the total. Thirty-nine per cent of consultants operated on the second ear. Of the 168 stapedectomies in which the hearing change was known at six months, 87 per cent achieved improved hearing, eight per cent had no change and five per cent were worse. The overall complication rate was 30 per cent with a 'dead ear' rate of two per cent.

Incudostapedial rebridging ossiculoplasty with bone cement.

OBJECTIVE: This study reports the authors' technique and hearing results with bone cement reconstruction of the incudostapedial chain. The technique is called incudostapedial rebridging ossiculoplasty. STUDY DESIGN: A retrospective analysis of the hearing results of the incudostapedial rebridging ossiculoplasty was performed on 15 patients. BACKGROUND: Recently, bone cements have been available commercially, and their use in otologic surgery is increasing. Polymaleinate glass ionomer cement is a commercially available bone cement that can be used to reconstruct a discontinuity between the incus and the stapes. SETTING: Tertiary referral center. PATIENTS: Disease-free or cleansed middle ear and mastoid and intact ossicular chain except for discontinuity between the long process of the incus and the head of the stapes. INTERVENTIONS: Therapeutic. MAIN OUTCOMES MEASURES: Functional results of incudostapedial rebridging ossiculoplasty. RESULTS: Of 15 patients, 9 achieved a successful hearing result (an air-bone gap within 20 dB) with incudostapedial rebridging ossiculoplasty after 1 year. The mean preoperative and postoperative air-bone gaps were 32.9 and 14.3 dB, respectively. CONCLUSIONS: Incudostapedial rebridging ossiculoplasty with bone cement is a cost-effective and safe procedure that yields good hearing results in selected patients.

Classification of congenital middle ear anomalies. Report on 144 ears.

The surgical findings in 144 successive ears operated on for congenital conductive hearing loss were analyzed, and the results were evaluated in terms of hearing gain. All the patients underwent middle ear surgery at the University Hospital Nijmegen between 1964 and 1990. A classification system was developed to analyze the findings. Class 1 comprises ears with congenital isolated stapes ankylosis. Class 2 comprises ears with congenital stapes ankylosis in combination with a congenital anomaly of the ossicular chain. Class 3 comprises ears with congenital anomalies of the ossicular chain and at least a mobile stapes footplate. Class 4 comprises ears with aplasia or severe dysplasia of the oval window or round window.

Stapedectomy - a 10 year review at Sunnybrook Hospital.

The authors wonder if the success rate with stapedectomy performed by a group of surgeons in a local general hospital can be expected to equal the results published from certain major centres. A 10 year review at Sunnybrook where 12 surgeons performed 160 operations showed a 78 per cent favorable result and an eight per cent unfavorable result in primary stapedectomy. In general older patients with more extensively affected footplates did worse. There were only minor differences between the results achieved with different prostheses, and virtually none between the various surgeons. Revision stapedectomy showed considerably worse results with 21 per cent achieving a favorable result against 42 per cent whose hearing became worse. A conservative approach to revision surgery is advised.
