Introduction: The anterior cervical approach is used to treat a variety of spinal disorders; among these, the Smith-Robinson approach is the most commonly used, as it allows access to discs, bony structures, and anterior lesions without directly affecting the spinal cord. Its use has increased as anterior discectomies and fusions are performed more frequently. Among the complications, dysphonia and dysphagia are the most common. Objectives: To describe the prevalence of dysphagia and dysphonia in patients with narrow cervical canal who were treated using an anterior cervical approach at the National Institute of Rehabilitation Materials and Methods: This study will consecutively enroll patients diagnosed with a narrow cervical canal who are treated using an anterior cervical approach at the INRLGII. The presence of dysphagia and dysphonia will be assessed in the postoperative period, at three months, and one year after surgery. Patients will be given rating scales to assess the presence and severity of symptoms during these three time periods. Study design: A prospective, longitudinal, observational, descriptive cohort study. Proposed statistical analysis: Clinical and demographic data will be described using summary measures (mean and median) for quantitative data and measures of dispersion (standard deviation, maximum, and minimum). The normality of the data will be tested using the Shapiro-Wilk test. The t-test will be applied to compare quantitative variables, and Pearson's chi-square test will be used for qualitative variables.
