About this study
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.
Read the detailed description
First Stage:
Upon admission of patients to the Spine Surgery Service with a prior diagnosis of cervical spinal stenosis, each patient will be informed about the surgical procedure, the type of approach, as well as the surgical risks and possible complications.
Second Phase:
Once patients agree to participate in the protocol, they will be given two scales. The first will be a vocal disability index, consisting of a 30-item questionnaire designed to assess the impact of speech dysfunction on the patient's daily life. The higher the score, the greater the disability. The second questionnaire is the EAT-10, a verbal, unidimensional, direct-scoring analog self-assessment scale designed to evaluate specific symptoms of dysphagia. It is a five-point scale (0-4 points), where zero (0) indicates the absence of the problem and four (4) indicates that the subject considers it a serious problem; higher scores will indicate a greater perception of dysphagia.
Third Phase:
This will take place during the postoperative period, approximately on the second or third day of recovery and before the patient begins eating solid foods. The questionnaires will be administered again to identify any differences and/or possible postoperative complications. Afterward, the patient will undergo a swallowing test, which involves inserting an endoscope (similar to a probe) through the nasal passage to the glottis, allowing visualization of the vocal cords. Subsequently, patients will swallow various food consistencies-liquid (water), semisolid (baby food), and solid (1/4 of a cookie)-viewed through a camera, reveal the state of the anatomical structures involved before and after swallowing. Prior to swallowing, the endoscope must be positioned on the soft palate, between the soft palate and the epiglottis, to visualize the base of the tongue and assess the passage of the food bolus into the pharynx; all of this is performed by a speech-language pathologist.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Fiberoptic Endoscopic Evaluation of SwallowingProcedure or surgery
Involves inserting an endoscope (similar to a probe) through the nasal passage to the glottis, allowing visualization of the vocal cords. Subsequently, patients will swallow various food consistencies-liquid (water), semisolid (baby food), and solid (1/4 of a cookie)-viewed through a camera, reveal the state of the anatomical structures involved before and after swallowing. Prior to swallowing, the endoscope must be positioned on the soft palate, between the soft palate and the epiglottis, to visualize the base of the tongue and assess the passage of the food bolus into the pharynx; all of this is performed by a speech-language pathologist.

The higher the score, the greater the disability.
EAT-10 questionnaireDiagnostic test
It is a five-point scale (0-4 points), where zero (0) indicates the absence of the problem and four (4) indicates that the subject considers it a serious problem; higher scores will indicate a greater perception of dysphagia.
What is being measured
The primary outcome is the main question the study is designed to answer.
Prevalence of dysphagia and dysphonia following anterior cervical spine surgery.
Number and percentage of participants presenting postoperative dysphagia after anterior cervical spine surgery, assessed using the Eating Assessment Tool-10, Bazaz Dysphagia Score, Dysphagia Short Questionnaire, and Flexible Endoscopic Evaluation of Swallowing when applicable.
Measured: 24 hours after surgery, 3 months after surgery, and 12 months after surgery
Secondary outcomes (8)
Postoperative pain assessed using the Visual Analog Scale
Postoperative pain intensity measured using the Visual Analog Scale. Scores range from 0 to 10, with higher scores indicating greater pain intensity.
Measured: 24 hours after surgery, 3 months after surgery, and 12 months after surgery
Cervical disability assessed using the Neck Disability Index
Cervical disability measured using the Neck Disability Index. Scores range from 0 to 50, with higher scores indicating greater disability.
Measured: Preoperative baseline, 3 months after surgery, and 12 months after surgery
Myelopathy severity assessed using the modified Japanese Orthopaedic Association score
Scale used to determine the degree of cervical spine disability according to upper-limb, lower-limb, and sphincter function. Scores range from 0 to 18, with lower scores indicating greater neurologic impairment.
Measured: Preoperative baseline, 3 months after surgery, and 12 months after surgery
Voice handicap assessed using the Voice Handicap Index
Thirty-item questionnaire with a 0 to 4 scale for each item. It evaluates the impact of voice dysfunction on daily life; higher scores indicate greater disability
Measured: Preoperative baseline, 3 months after surgery, and 12 months after surgery.
Dysphagia-related handicap assessed using the Eating Assessment Tool-10
Dysphagia-related symptoms measured using the Eating Assessment Tool-10. Scores range from 0 to 40, with higher scores indicating greater swallowing-related symptom burden.
Measured: Preoperative baseline, 24 hours after surgery, 3 months after surgery, and 12 months after surgery.
Length of hospital stay
Number of days from surgery to hospital discharge.
Measured: From date of surgery to date of hospital discharge, up to 30 days
Postoperative complications
Number and percentage of participants with postoperative complications after anterior cervical spine surgery.
Measured: From surgery to 12 months after surgery.
Quality of life assessed using the Short Form-36 Health Survey
Health-related quality of life measured using the Short Form-36 Health Survey. Higher scores indicate better health-related quality of life.
Measured: Preoperative baseline, 3 months after surgery, and 12 months after surgery.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Prevalence of dysphagia and dysphonia following anterior cervical spine surgery. (time frame: 24 hours after surgery, 3 months after surgery, and 12 months after surgery). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07713693, which also lists 18 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Nov 2026.
