All the patients were followed up more than 12 months. The patients\u2019 medical data, as well as pre- and postoperative radiologic findings were thoroughly investigated. The visual analogue score (VAS), Japanese Orthopaedic Association (JOA) score, cervical dysfunction index (Neck disability index, NDI), and modified MacNab criteria were used to assess the surgical efficacy.Results : All the patients were successfully treated with PECF using ultrasonic osteotome. The pre- and postoperative VAS, NDI, and JOA scores were significantly improved (p&lt;0.05). According to the modified MacNab criteria, 17 patients were assessed as \u201cexcellent\u201d, two patients were assessed as \u201cgood\u201d at the last follow-up. There was no dura tear, nerve root damage, incision infection, neck deformity, or other complications.Conclusion : Adequate nerve root decompression can be accomplished successfully with the help of ultrasonic osteotome in PECF, which has the advantage of reducing the probability of damage to the nerve root and dura mater, in addition to the original merits of endoscopic surgery.<\/jats:p>","DOI":"10.3340\/jkns.2022.0233","type":"journal-article","created":{"date-parts":[[2022,12,12]],"date-time":"2022-12-12T02:35:00Z","timestamp":1670812500000},"page":"426-437","update-policy":"https:\/\/doi.org\/10.3340\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Ultrasonic
