AIM: The present study purpose was to investigate the nasal polyposis endonasal microsurgery efficacy, evaluating the number of disease recurrence according to sex, age, stage and patients' professions examined at the Otholaryngology Department and Head and Neck Surgery, Medical School, São José do Rio Preto-FAMERP. STUDY DESIGN: Clinical study with cohort longitudinal. MATERIAL AND METHOD: Thirty patients were submitted to endonasal microscopic surgery in the period of 1991 to 1996, 16 females and 14 males in a post-operative follow-up from one to five years. RESULTS: Recurrence frequency was 40 %, and the predominance was statistically significant (chi-square and Fisher tests, values p=0.03 and 0.024, respectively) in males (75%). Synechia complication could be observed in four (13,3 %) cases. CONCLUSION: It was concluded that endonasal microsurgery in nasal polyposis has permitted 60 % of the patients to be free from recurrence of disease in the follow-up period, with greater frequency among males. This technique showed to be effective in the nasal polyposis treatment, just presenting synechia complication in 13.3 % of the cases.
