Surgical excision can be done with diathermy knife, cryosurgery, or laser surgery. During surgery, cauterization of the base of the pedicle is advocated.
Recurrence rate is high. During surgical excision, utmost care of asepsis must be taken as the spores can give rise to new seedling to the patient and as well as operating staff.
Surgical removal by FESS:
FESS helps in minimizing the recurrence rate, as the pedicle is removed and cauterized under direct vision. Recent advances suggest usage of coblation to excise the rhinosporidiosis.
