    This study reports on primary cricopharyngeal achalasia treatment using muscle division and diverticulum inversion. This approach effectively restores normal swallowing in patients with this sphincter dysfunction.

    Area of Science:

    • Gastroenterology
    • Otolaryngology
    • Surgical Innovation

    Background:

    • Cricopharyngeal achalasia is a rare swallowing disorder.
    • Pharyngoesophageal diverticula can occur secondary to sphincter dysfunction.
    • Traditional treatments may involve more invasive procedures.

    Purpose of the Study:

    • To report new cases of primary cricopharyngeal achalasia.
    • To evaluate the efficacy of posterior cricopharyngeus muscle division and diverticulum inversion for sphincter dysfunction.
    • To highlight the benefits of this surgical approach.

    Main Methods:

    • Retrospective review of six new cases of primary cricopharyngeal achalasia.
    • Analysis of eight additional cases of secondary pharyngoesophageal diverticulum.

  • Surgical treatment involved posterior cricopharyngeus muscle division and diverticulum inversion.
  • Clinical and cineradiographic assessments of swallowing function.

    • Main Results:

    • Restoration of normal or near-normal swallowing was observed in treated patients.
    • Surgical intervention effectively addressed sphincter dysfunction.
    • Cineradiographic evidence supported improved pharyngoesophageal function.

    Conclusions:

    • Posterior cricopharyngeus muscle division and diverticulum inversion is a valid and effective treatment for cricopharyngeal achalasia and secondary pharyngoesophageal diverticulum.
    • Local anesthesia allows direct observation of swallowing pathophysiology and precise muscle division.
    • This technique enables immediate functional recovery in older patients.
