Surgery for acquired cholesteatoma in children: long-term results and recurrence of cholesteatoma.

The aim of the study was to evaluate the long-term results after surgery for acquired cholesteatoma in children and to contribute to the search for predictors of recurrence. During a 15-year period, 114 children underwent surgery. The patients were re-evaluated with a median observation time of 5.8 years. At the last re-evaluation 85 per cent of the ears were dry with an intact drum. Recurrence of cholesteatoma developed in 27 ears. The cumulated total recurrence rate was 24 per cent using the incidence rate calculation, applying Kaplan-Meier survival analysis the corresponding recurrence was 33 per cent. Recurrent disease occurred significantly more frequently in children younger than eight years, with a negative pre-operative Valsalva, with ossicular resorption and with large cholesteatomas. In conclusion, young children with poor Eustachian tube function and a large cholesteatoma with erosion of the ossicular chain, are at special risk of recurrence and should be observed for several years after surgery.

Prognostic factors in tympanoplasty.

OBJECTIVE: To assess the prognostic value of pathologic and technical variables influencing the functional outcome of tympanoplasty. PATIENTS AND STUDY DESIGN: Retrospective review of the records of 544 patients affected by chronic otitis with or without cholesteatoma, operated on by the senior author in a city hospital ENT department. Follow-up was provided systematically by the same institution. INTERVENTIONS: These included tympanoplasty without mastoidectomy in 339 cases, canal wall up technique in 134 cases, and canal wall down in 71 cases. Three hundred twenty-six (60%) were primary, and 218 (40%) were revision procedures. Myringoplasty was performed with autologous temporalis fascia, ossiculoplasty with incus interposition, or partial or total ossicular prostheses. Mean follow-up was 14 months (range, 12-50 months). MAIN OUTCOME MEASURES: Hearing results were defined according to the Committee on Hearing and Equilibrium Guidelines. A one-way analysis of variance was used to determine group differences. Multiple logistic regression analysis was subsequently carried out on the different pathology groups via the hierarchical log linear model. A probability value of p < 0.05 was the level of significance. RESULTS: The status of the mucosal lining, the mastoidectomy, the availability of the malleus handle, and the tympanic membrane perforation were all significantly predictive of the hearing outcome but with differing weight according to the pathologic condition. CONCLUSIONS: Anatomic and technical factors diversely affect the functional outcome of tympanoplasty. A better knowledge of their predictive roles and weights may be useful in both the surgeon's judgment and in the information given to the patient.

[Problems in cochlear implant surgery].

In cochlear implant surgery, major complications, requiring revision procedures, do not exceed 5% of cases reported. Less frequent are problems that call for specific technical solutions. In 44 multichannel implantations (out of 54 cases) adverse conditions occurred and were successfully resolved in 6 patients: 1) delayed wound breakdown (one case); 2) chronic otitis media (three cases); 3) cochlear obliteration (two cases). Problem 1 was managed with the excision of an ellipse of skin including the devitalized areas under local anesthesia. The electronic package was left untouched, and the freshly cutaneous edges were mobilized and layer-sutured. Problem 2 was solved through a two-stage procedure. The chronic ear was dealt with as usual (myringoplasty, tympanoplasty, revision of a radical mastoidectomy). In the second stage the cochleotomy and device implantation were carried out. Problem 3 is a major issue for the surgeon. Following the Lehnhardt technique we drilled along the basal cochlear turn using the sharp line between the yellowish otic bone and the white newly formed bone as a landmark, until a patent s.tympani was found at the ascending part of the 1st or at the beginning of the 2nd turn.

[Selective vestibular neurectomy: a comparison of techniques].

The surgical treatment of patients suffering from incapacitating peripheral vertigo is still controversial. In the ENT Department of the Civil Hospital of Venice 43 patients with disabling menieric vertigo spells underwent a selective vestibular nerve section employing either a retrosigmoid (25 cases) or a retrolabyrinthine approach (18 cases) between 1991 and 1993. The two approaches are compared with regard to surgical technique, pre- and postoperative complications and i.e. functional results, i.e. vertigo control and hearing preservation. Functional results, classified according to the guidelines reported by the Committee on Hearing and Equilibrium of the AAO-HNS in 1985 did not show substantial differences. We obtained complete vertigo control in 95% of the patients and hearing was conserved at the preoperative level in almost all of the cases. The retrosigmoid approach demonstrated distinct advantages with regard to the surgical technique employed; it was faster, offered a wider surgical field in the cerebello-pontine angle and brought about fewer peri- and postoperative complications.
