Precise targeting of the infraorbital nerve is essential for successful intervention, yet anatomical variability often limits the consistency of conventional radiofrequency ablation (RFA). This report describes a medial-to-lateral ultrasound- and computed tomography-guided approach, intended to align with the natural orientation of the infraorbital canal and potentially enhance electrode\u2013nerve contact. A 48-year-old woman with refractory maxillary incisor pain underwent RFA after only transient benefit from a diagnostic nerve block. Ultrasound enabled accurate identification of the infraorbital foramen and confirmed the canal\u2019s medial-to-lateral course, which then guided CT-assisted needle advancement into the orbitomaxillary segment. The patient experienced immediate analgesia. Pain reduction was maintained at the one-month follow-up. At the two-month assessment, although a mild symptom rebound was observed, no procedure-related complications were noted. This trajectory-based medial-to-lateral technique offers an anatomically grounded alternative for infraorbital nerve RFA and may represent a valuable option for refractory PIDAP.<\/jats:p>","DOI":"10.3390\/diagnostics16020254","type":"journal-article","created":{"date-parts":[[2026,1,13]],"date-time":"2026-01-13T15:52:57Z","timestamp":1768319577000},"page":"254","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Ultrasound- and CT-Guided Medial-to-Lateral Radiofrequency Ablation of the Infraorbital Nerve for Persistent Idiopathic Dentoalveolar Pain: A Trajectory-Based Approach"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3679-2698","authenticated-orcid":false,"given":"Sz-Tsan","family":"Wang","sequence":"first","affiliation":[{"name":"Center for Multidisciplinary Pain Management, Dalin Tzu Chi Hospital Buddhist Tzu Chi Medical Foundation, Chiayi 622, Taiwan"},{"name":"Division of Allergy and Immunology and Rheumatology, Dalin Tzu Chi Hospital Buddhist Tzu Chi Medical Foundation, Chiayi 622, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7558-5651","authenticated-orcid":false,"given":"Ke-Vin","family":"Chang","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, National Taiwan University Hospital, Bei-Hu Branch, No. 87, Nei-Jiang Rd., Wan-Hwa District, Taipei 108, Taiwan"},{"name":"Department of Physical Medicine and Rehabilitation, National Taiwan University College of Medicine, Taipei 100, Taiwan"},{"name":"Center for Regional Anesthesia and Pain Medicine, Wang-Fang Hospital, Taipei Medical University, Taipei 116, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7511-9629","authenticated-orcid":false,"given":"Wei-Ting","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Physical Medicine and Rehabilitation, National Taiwan University Hospital, Bei-Hu Branch, No. 87, Nei-Jiang Rd., Wan-Hwa District, Taipei 108, Taiwan"},{"name":"Department of Physical Medicine and Rehabilitation, National Taiwan University College of Medicine, Taipei 100, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2713-4071","authenticated-orcid":false,"given":"Levent","family":"\u00d6z\u00e7akar","sequence":"additional","affiliation":[{"name":"Department of Physical and Rehabilitation Medicine, Hacettepe University Medical School, Ankara 06100, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"129","DOI":"10.1177\/0333102419893823","article-title":"International classification of orofacial pain, (ICOP)","volume":"40","author":"Benoliel","year":"2020","journal-title":"Cephalalgia"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"518548","DOI":"10.1155\/2012\/518548","article-title":"Current evidence on atypical odontalgia: Diagnosis and clinical management","volume":"2012","author":"Abiko","year":"2012","journal-title":"Int.
