The usage of normal saline (NS), 5% dextrose water (D5W), platelet\u2010rich plasma (PRP), and hyaluronic acid (HA) as primary injectates for hydrodissection without an anesthetic can limit anesthetic\u2010related toxicity and preserve the motor functions of the median nerve. Here, we describe a novel motor\u2010sparing neural injection and compare the effect of these four injectates for severe CTS. We retrospectively reviewed the outcomes of 61 severe CTS cases after a single neural injection with NS, D5W, PRP, or HA. Outcomes were evaluated on the 1<jats:sup>st<\/jats:sup> and 6<jats:sup>th<\/jats:sup> months postinjection, including the Boston Carpal Tunnel Questionnaire (BCTQ) scores and the nerve cross\u2010sectional area (CSA). The results revealed that PRP, D5W, and HA were more efficient than NS at all measured time points (<jats:italic>p<\/jats:italic> &lt; 0.05), except for CSA at the 1<jats:sup>st<\/jats:sup> month between the NS and D5W groups. Single\u2010injections of PRP and D5W seemed more effective than that of HA within 6 months postinjection for symptom and functional improvement (6<jats:sup>th<\/jats:sup>\u2010month BCTQ\u2010symptom, D5W vs. HA, <jats:italic>p<\/jats:italic> = 0.047; 1<jats:sup>st<\/jats:sup>\u2010month BCTQ\u2010symptom, PRP vs. HA, <jats:italic>p<\/jats:italic> = 0.018; 1<jats:sup>st<\/jats:sup>\u2010 and 6<jats:sup>th<\/jats:sup>\u2010month BCTQ\u2010function, D5W vs. HA, <jats:italic>p<\/jats:italic> = 0.002 and 0.016, respectively; 1<jats:sup>st<\/jats:sup>\u2010month BCTQ\u2010function, PRP vs. HA, <jats:italic>p<\/jats:italic> &lt; 0.001).
