ABSTRACT
OBJECTIVE:
To report the efficacy and safety of electromyography-guided percutaneous botulinum toxin injection into the cricopharyngeus muscle in an office setting for treatment of the inability to belch and associated symptoms caused by retrograde cricopharyngeus dysfunction (R-CPD). STUDYDESIGN:
Retrospective case series of treated patients.SETTING:
Tertiary care laryngology clinic.METHODS:
A retrospective review was performed on 18 consecutive patients who were diagnosed syndromically with R-CPD. The combined diagnostic test and treatment-specifically, botulinum toxin injection into the cricopharyngeus muscle-was accomplished in an office setting by a single surgeon using electromyography guidance. Items assessed are efficacy, safety, complications, and duration of benefit.RESULTS:
All 18 patients (100%) treated in the in-office setting gained the ability to burp with improvement in the associated symptoms of R-CPD at initial follow-up. Of those who had the in-office procedure performed initially, 80% maintained the ability to burp at 6 months with relief of all the associated symptoms of R-CPD. No patients experienced permanent complications from the injection, but 7 patients experienced varying degrees of noisy breathing within 1 week after the procedure, which was managed with breathing techniques and resolved.CONCLUSION:
In a case series of 18 patients with R-CPD, all patients gained the ability to burp with improvement in the majority of their symptoms of R-CPD at the time of their initial follow-up at 1 week. None experienced severe complications, and 7 experienced transient noisy breathing, which resolved.
