Summary
This study highlights the safe resection of a rare right-sided Zenker's diverticulum using intraoperative neuromonitoring to prevent recurrent laryngeal nerve injury. This technique aids in identifying nerve variations during surgery.
Area of Science:
- Gastroenterology
- Otolaryngology
- Surgical Neurology
Background:
- Right-sided Zenker's diverticulum is a rare condition.
- Transcervical diverticulectomy carries a high risk of recurrent laryngeal nerve injury due to anatomical variations.
Observation:
- A 55-year-old male presented with chronic cough and regurgitation.
- Diagnosis was right-sided Zenker's diverticulum requiring open transcervical diverticulectomy and cricopharyngeal myotomy.
Findings:
- Intraoperative neuromonitoring successfully identified the right recurrent laryngeal nerve's location.
- The nerve's position was confirmed via intermittent stimulation during dissection, preventing injury.
Implications:
- Intraoperative neuromonitoring is a beneficial tool for transcervical diverticulectomy of right-sided Zenker's diverticulum.
- This technique can mitigate the risk of vocal cord paralysis by avoiding recurrent laryngeal nerve damage.
