Investigations on human subjects should conform to accepted ethical standards. Fully informed consent should be obtained and noted in the manuscript. For all manuscripts dealing with experimental work involving human subjects, specify that informed consent was obtained following a full explanation of the procedure (s) undertaken, and if requested by the journal’s editorial board, the authors should produce the copy of ethical clearance. Patients should be referred to by number; do not use real names or initials. Also, the design of special scientific research in human diseases or of animal experiments should be approved by the ethical committee of the institution or conform to guidelines on animal care and use currently applied in the country of origin. It is the author's responsibility to ensure patient's anonymity. In images or illustrations, patient’s eyes should be masked. However, if the eye area is the focus of illustration, patient's nose and mouth should be masked and written consent must be obtained from the patients/legal guardian. Patients' names should be removed from the figures, radiographs, and CT scans, unless written consent is obtained.
