Recently, we have been requested to prepare ‘Author’s reply to the letter, to the editor of Journal of the Korean Association of Oral and Maxillofacial Surgeons (JKAOMS)’ for the reply article ‘Reply to the brief communication “Essential review points on the retrospective study of osteoradionecrosis in the jaws”’, by Manzano and da Silva Santos ¹ . The main seven points of views of mine from the original article by Manzano et al. ² , entitled, ‘Retrospective study of osteoradionecrosis in the jaws of patients with head and neck cancer’ were already published ³ . Thus, I would like to respond to reply as below.

Regarding our seven points of brief communications ³ , authors replied accurately and edited under the better information. They emphasized again that less invasive treatment options were the first choice for osteoradionecrosis (ORN) management, clear standards of ORN stages in their retrospective clinical studies, beginning and clinical progress of ORN, multimodal management of ORN, additional explanation of studied patients’ numbers by corrections of Tables, and their protocol of using cobalt and intensity-modulated radiation therapy (IMRT) for reducing ORN risks, were easier explained to understand. I am very grateful for these good reply and correct expressions. In addition, my family name is Kim, not Kin. And our previous published article ⁴ , entitled as ‘The effects of pentoxifylline and tocopherol in jaw osteomyelitis’, was to investigate the effect of pentoxifylline and tocopherol in patients diagnosed with ORN, bisphosphonate-related osteonecrosis of jaw, and chronic osteomyelitis using digital panoramic radiographs, not for the ORN only.

Through these processes, I hope that this will serve as an opportunity to identify more important review points in retrospective research on ORN, and to become a JKAOMS journal that delivers more accurate and high-level clinical scientific knowledge to the international readers.
