Cricopharyngeal myotomy: indications and technique

Area of Science:

• Otolaryngology
• Gastroenterology
• Surgical Innovation

Background:

• Current diagnostic tests for cricopharyngeal dysmotility are costly, invasive, and lack predictive accuracy for surgical outcomes.
• Block dysphagia, localized to the cricoid level without evidence of malignancy on esophagram, indicates potential benefit from cricopharyngeal myotomy.

Purpose of the Study:

• To present an effective surgical technique for cricopharyngeal myotomy.
• To highlight the diagnostic utility of cricopharyngeal myotomy in specific dysphagia cases.
• To report outcomes from a series of 54 cricopharyngeal myotomies.

Main Methods:

• Utilizing muscular distention via an inflated endotracheal tube cuff to delineate muscle fibers.
• Performing a posterior midline incision of the cricopharyngeus, hypopharynx, and upper esophagus.
• Employing a "peanut" sponge in a Kelly clamp to precisely divide remaining muscle fibers, minimizing perforation risk.

Main Results:

• The described technique ensures adequate muscle fiber distention and precise division.
• Risks of esophageal perforation and incomplete muscle transection are minimized.
• Experience with 54 successful cricopharyngeal myotomies is detailed.

Conclusions:

• Cricopharyngeal myotomy serves as a valuable diagnostic and therapeutic intervention for specific types of dysphagia.
• The presented surgical method offers improved accuracy and safety compared to existing diagnostic approaches.
• This technique effectively addresses cricopharyngeal muscle dysfunction, leading to improved patient outcomes.
