CT scanning in "second look" combined approach tympanoplasty.

One of the main disadvantages of intact canal wall mastoid surgery for cholesteatoma is the necessity of the "second look". The morbidity of a second procedure can be reduced, however, with the aid of a rigid endoscope. Fifty-five consecutive patients undergoing a re-exploration were included in this study. Prior to surgery computerized tomography (CT) was performed in order to assess both the anatomy and degree of pneumatisation of the middle ear cavity and mastoid bowl. The operative findings at the time of the "second look" were correlated with the pre-operative scans. An otoendoscopic approach was possible in all cases. In the diagnosis of residual or recurrent disease, the CT scan had a sensitivity of 43.8%. The specificity of the CT scan was 51.3%. The explanation for these findings is that it is impossible to differentiate between recurrence, scar tissue or inflammation on CT images in patients who have undergone previous mastoid surgery.

Canal-wall-down tympanoplasty with mastoidectomy for advanced cholesteatoma.

OBJECTIVE: The objective of this study was to review 8.5 years of the senior author's experience with canal-wall-down mastoid surgery for extensive cholesteatoma with high-grade atelectasis and severely destructed ossicles. DESIGN: A retrospective review was conducted. SETTING: The setting was a tertiary care medical centre. METHODS: Available records consulted included 104 canal-wall-down mastoidectomy for advanced-stage cholesteatomas between July 1984 and December 1992. MAIN OUTCOME MEASURES: Recurrence, hearing results, and dry ear rate were analyzed. RESULTS: The recurrence rate was 4 of 104 (3.8%), and 9.6% of subjects suffered from recurrent otorrhea. Thirty-seven of 104 (35.6%) achieved the closure of air-bone gap within 20 dB. The availability of stapes suprastructure influenced the postoperative hearing level significantly (p < .001). CONCLUSION: Even in treating advanced cholesteatoma, canal-wall-down mastoidectomy provides a low recurrence rate, establishes a high dry ear rate, and preserves adequate hearing when the stapes suprastructure is available for reconstruction.

Formaldehyde-formed autogenous fascia graft tympanoplasty.

The formaldehyde-formed autogenous fascia graft represents another step toward more reliable functional restoration of the diseased tympanic membrane. It combines the advantages of the availability and high nonperforation rate of autogenous fascia with the more normal anatomic restoration experienced with homograft tympanic membrane grafts. Its primary indication is in total membrane perforations with intact malleus although the concept can be employed in conjunction with various types of ossicular reconstruction.

[The concept of endaural tympanoplasty for severe congenital atresia auris (author's transl)].

The recommendation of a strictly endaural approach to the tympanic cavity in congenital atresia is based on a series of 26 cases of severe malformations (grade II and III). Two bony ridges at the lower edge of the atresial plate and the deep auricular artery served as landmarks. A bony posterior canal wall was always conserved or reconstructed. There was no collision with the facial nerve. The reobliteration of the new external auditory canal was avoided by four means: sufficient resection of both overlying soft tissue and the parotid gland, insertion of auto- or homologous cartilage into the anterior canal wall, Z-plasty of the buccal skin, and delayed implantation of split skin. The average gain of air conduction was 19 dB IN 14 controlled ears.

[Tympanoplasty of today (author's transl)].

The author explains why he developed the access to the meso-hypotympanum via the angle between the facial nerve and the chorda tympani in 1953 which he then demonstrated at many occasions. The value of this access--later used by other ear surgeons and named mastoidectomy with intact canal wall technique or posterior tympanotomy--for chronic otitis media was always denied by the author. These methods do not give sufficient way to the main focus of pathology in the epitympanum mainly to the pretympanic recess in front of the head of the malleus; The danger of deep penetrating cholesteatoma in the petrous bone is too great. Only complete opening combined with complete reconstruction serves really eradicating the pathology completely as well as full reconstruction of the middle ear and the external canal; this means osteoplastic epitympanotomy. With the help of this operation it is possible to continue in the same stage with complete mastoidectomy and complete sinus operation.
