RESUMO
As sinéquias constituem a complicação pós-operatória mais frequente das cirurgias endoscópicas sinusais, chegando a 36% dos casos. Na tentativa de diminuir esse índice, inúmeros materiais têm sido utilizados, dentre eles a Mitomicina-C (MMC).

OBJETIVO:

Avaliar a eficácia da MMC tópica na prevenção de sinéquias após cirurgias sinusais em humanos.

MÉTODO:

Ao final das cirurgias, colocava-se cotonoide com MMC (1,0 mg/ml) em um dos meatos médios (grupo MMC) e outro embebido em solução salina, no meato médio contralateral (grupo controle), por 5 minutos, de forma randomizada e com o avaliador cego em relação aos lados. As sinéquias foram classificadas em parciais, quando não fechavam totalmente os meatos médios, e totais, quando a oclusão era completa.

Desenho:

prospectivo.

RESULTADOS:

No grupo MMC, ocorreram três sinéquias (21,43%) versus nove (64,29%) no grupo controle (p = 0,054). No grupo MMC, todas as três (21,43%) foram parciais, enquanto no grupo controle houve quatro (28,57%) parciais e cinco (35,71%) totais (p = 0,025).

CONCLUSÃO:

A MMC não foi eficaz na prevenção sinéquias como um todo, porém, preveniu a formação de sinéquias totais.
ABSTRACT
Synechia is the most frequent complication after sinus surgery and has been reported in up to 36% of cases. Several types of materials have been used to reduce the incidence of synechia, including Mitomycin C (MMC).

OBJECTIVE:

This prospective study aimed to assess the effectiveness of topical MMC in the prevention of synechia after sinus surgery in humans.

METHODS:

At the end of surgery, MMC solution (1.0 mg/ml) was topically applied randomly to one of the middle meatuses (MMC group) of 14 patients while saline solution was applied to the contralateral meatus (control group). The author remained blind to the medicated side. Synechiae were classified as partial or total.

RESULTS:

Three patients had middle meatus synechia in the MMC group (21.43%) versus nine (64.29%) in the control group (p = 0.054). In the MMC group, all three middle meatus synechia were partial, while in the control group there were four partial (28.57%) and five total (35.71%) cases of synechia (p = 0.025).

CONCLUSIONS:

Mitomycin C was not effective in preventing middle meatus synechia, but reduced the probability of total synechia formation.
