Abstract
Background: Bisphosphonates may cause serious adverse events, including osteonecrosis of the jaw. This article describes a case of successful application of radiofrequency thermocoagulation for pain caused by osteonecrosis of the jaw.
Case presentation: An 86-year-old woman who had received alendronate sodium hydrate for osteoporosis was diagnosed with osteonecrosis of the right mandible after dental treatment. Despite repeated conservative and debridement treatments, the patient could not eat due to intractable pain; accordingly, her condition was debilitated. The patient was referred to our pain management clinic for radiofrequency thermocoagulation of the right mandibular nerve. Immediately after the procedure, her pain drastically improved and she could eat; moreover, the pain has not recurred for 3 years.
Conclusion: Our findings demonstrate that minimally invasive radiofrequency thermocoagulation may have long-term effects in patients with chronic pain caused by osteonecrosis of the jaw that is refractory to conservative treatment.
期刊介绍:
JA Clinical Reports is a companion journal to the Journal of Anesthesia (JA), the official journal of the Japanese Society of Anesthesiologists (JSA). This journal is an open access, peer-reviewed, online journal related to clinical anesthesia practices such as anesthesia management, pain management and intensive care. Case reports are very important articles from the viewpoint of education and the cultivation of scientific thinking in the field of anesthesia. However, submissions of anesthesia research and clinical reports from Japan are notably decreasing in major anesthesia journals. Therefore, the JSA has decided to launch a new journal, JA Clinical Reports, to encourage JSA members, particularly junior Japanese anesthesiologists, to publish papers in English language.
