[Stapedotomy, stapedectomy and revision surgery performed with laser techniques. Revision of literature].

The usefulness of laser in otologic surgery, and specifically the suitability of its use in stapes surgery, is still under discussion. We intend to support the use of this method in the surgical treatment of otosclerosis, as well as to elucidate which type of laser is the most advisable one, establishing also in which stages of surgery it should be used. For this, we carry out a revision of the main opinions published in this regard in the international literature, commenting on the results and observations gathered in it. We end by setting out a number of conclusions which are the result of the analysis of the criteria put forward in the bibliography.

Immunobiological peculiarities of cholesteatoma in children: quantification of epithelial proliferation by MIB1.

Cholesteatoma in children is characterized by a more extensive and rapid growth in the middle ear and mastoid cavities. The growth characteristics of the cholesteatoma in 20 children were studied using the monoclonal antibody MIB 1, which recognizes a nuclear antigen expressed by cells in the G1, S, and G2/M phases. Specimens of normal adult auditory meatal skin (n = 15) and adult cholesteatoma (n = 15) served as controls. The tissue specimens were prepared for immunohistochemical examination using the alkaline phosphatase-antialkaline phosphatase method and an automatic image analyzer. Specimens of normal skin revealed an average MIB 1 score of 9.2 +/- 3.10%. Child and adult cholesteatomas showed higher values. The average MIB 1 score was higher in child cholesteatoma (42 +/- 9.4%) than in adult cholesteatoma (28.2 +/- 6%). This difference was statistically significant (P<.01). Our results confirm a significant increase of the proliferative rate of cholesteatoma keratinocytes in children, giving an explanation for the more aggressive clinical behavior observed in these patients.
