The authors modified a Hardy nasal speculum to improve the access to surgical fields and the handling of various instruments during transsphenoidal surgery. A section of the inferior edge of the speculum was cut out 2 cm from its orifice on both sides. The thickness of the tip of the speculum was also reduced. The authors are prepared to operate using a variety of speculum lengths (the distance between the tip and the cutting level), and this length is selected depending on the distance between the anterior wall of the sphenoid sinus and the surface of the gingiva in the individual patient. A modified nasal speculum was used in transsphenoidal surgery for a pituitary adenoma. With use of this device, the protrusion of the speculum above the gingiva was markedly decreased.
