Summary

Introduction: The merging of medicine with information technology facilitates the retrieval of stored data, aiding the conduct of research with greater scientific rigor. Studies in the field of otorhinolaryngology, specifically in the area of laryngology and voice, are of fundamental importance, since 70% of the economically active need their voice to work.

Objective: To create a computerized protocol of the diseases of the larynx, apply and validate it, and use it to evaluate patients undergoing laryngoscopic microsurgery of the larynx.

Method: We created a database of ENT diseases through a literature review of textbooks and scientific articles. Next, we computerized the data and incorporated it into the SINPE©, creating a master protocol (ENT diseases) and a specific protocol (laryngeal diseases). Data were collected prospectively from patients undergoing laryngeal microsurgery in the ENT Hospital of Paraná. The collected data were analyzed with graphs through the SINPE© Analyzer module.

Results: We evaluated 245 patients aged 9–79 years, and determined that 36.61% (93 patients) underwent surgery for the presence of polyps on the vocal folds, 12.6% (32) underwent surgery for papillomatosis, and 11.83% (29) underwent surgery for intracordal cysts.

Conclusions: The creation of an electronic database of clinical ENT diseases was feasible. We were also able to implement and validate the protocol. The database may be released to physicians involved in clinical data collection and retrieval of information to conduct scientific research in an organized manner. The most common laryngeal disorders identified were polyps, papilloma, and intracordal cysts.
