Abstract: In one aspect, a method of redesigning a laryngoscope, a pharyngoscope, or an oral cavity retractor is disclosed, which includes generating a computerized 3-D model of a laryngoscope, pharyngoscope, or an oral cavity retractor, adjusting one or more parameters of the 3-D model to obtain a 3-D design of a laryngoscope, pharyngoscope, or oral cavity retractor that can provide a desired visual access to the upper aerodigestive tract of a patient or a group of patients, and fabricating a laryngoscope, pharyngoscope, or an oral cavity retractor based on said 3-D design using an additive manufacturing technique, such as 3-D printing.
