Abstract:
Precise bimanual microsurgical excision of sessile, thin benign epithelial lesions of the vocal folds can be difficult. During microlaryngeal surgery, the potential risks of over-excision and under-excision are of major concern. We introduce a microsurgical technique using horizontally-opening curved microforceps and microscissors, instead of the conventional vertically-opening microinstruments, to remove vocal nodules and simple epithelial hyperplasia. The treatment results were satisfactory, with 208 (90.8 per cent) of patients retaining a satisfactory/normal (G(0)) voice. No patient had a worsened voice after the procedure. This microsurgical pressing excision technique is an alternative precise method for microlaryngosurgery.
