Their mean (SD) age at symptom onset was 13.6 (7.7) years, and at diagnosis, 30.4 (6.4) years. Sixty-eight patients (64.2%) had potential congenital R-CPD, according to the parents\u2019 testimonies. A family history was reported in 18 of 62 cases (29.0%). In 105 cases (99.1%), patients made the diagnosis themselves despite medical consultations (n\u2009=\u2009162), empirical treatments (n\u2009=\u2009113), and additional examinations (n\u2009=\u200992). The cumulative success rate of BTI was 90.6% (96 of 106 patients). In 26 cases (24.5%), additional injections were administered to address the symptoms. Family history of R-CPD was a negative predictor of single-BTI success. Dysphagia was the primary adverse effect occurring after 89 of 126 BTIs (70.6%) and lasted a mean (SD) of 16.3 (12.0) days. In 10 cases, operating-room BTI was administered after primary in-office BTI.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"ab-obr240006-10\">\n                    <jats:title>Conclusions and Relevance<\/jats:title>\n                    <jats:p>R-CPD is an emerging and poorly known disorder associated with high rates of ineffective consultations, additional examinations, and self-diagnosis by patients.
