Editorial Policies for Authors
As stated in the Uniform Requirements, credit for authorship requires substantial contributions to (a) the conception and design or analysis and interpretation of the data, and (b) the drafting of the article or critical revision for important intellectual content. Any change in authorship after submission must be approved in writing by all authors.
Conflict of interest
A conflict of interest may exist when an author (or the author’s institution or employer) has financial or personal relationships that could inappropriately influence (or bias) the author’s decisions, work, or manuscript.
Corresponding author of an article is asked to let the Editor-in-Chief know potential conflict of interest possibly influencing their interpretation of data. Potential conflict of interest is applied even when the authors are confident that their judgments have not been influenced in the manuscript. Such conflicts may be financial supports or connections to pharmaceutical companies, political pressure from interest groups, or academic problems.
The Editor-in-Chief will decide whether the information of the conflict should be included in the published paper. Before publishing such information, the Editor-in-Chief will consult with the corresponding author.
In particular, all sources of funding for a research should be explicitly stated. CEO asks referees to let its Editor-in-Chief know of any conflict of interest before reviewing a particular manuscript.
For clinical trials, details of ethical committee approval and the type of informed consent should be stated. Patients’ and volunteers’ names, initials, and hospital numbers should not be used. We endorse the principles embodied in the Declaration of Helsinki and expect that all investigations involving human materials have been performed in accordance with these principles. For animal experiment, “the Guiding Principles in the Care and Use of Animals” approved by the American Physiological Society have to be observed.
No substantial part of the manuscript may have been or may be published elsewhere. This restriction does not apply to abstracts or press reports published in connection with scientific meetings. For advice on previous or simultaneous publication, contact the Editorial Office.
Articles published in CEO are open-access, distributed under the terms of the Creative Commons Attribution Non-Commercial License (http://creativecommons.org/licenses/by-nc/4.0), which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited.
Upon acceptance of an article, authors will be asked to transfer copyright. This transfer will ensure the widest possible dissemination of information. A letter will be sent to the corresponding author confirming receipt of the manuscript. A form facilitating transfer of copyright will be provided.
If excerpts from other copyrighted works are included, the author(s) must obtain written permission from the copyright owners and credit the source(s) in the article.
Requests may also be completed online: http://www.e-ceo.org
Alteration in proof
CEO provides the corresponding author with galley proofs for their correction. Corrections should be kept to minimum. The Editor retains the prerogative to question minor stylistic alterations and major alterations that might affect the scientific content of the paper. Fault found after the publication is a responsibility of the authors. We urge our contributors to proofread and their accepted manuscript very carefully. The corresponding author may be contacted by the Editorial Office, depending on the nature of correction in proof. If the proof is not returned to the Editorial Office within 48 hours, it may be necessary to reschedule the paper for a subsequent issue.
For the policies on the research and publication ethics not stated in this instructions, ‘Good Publication Practice Guidelines for Medical Journals (http://kamje.or.kr/publishing_ethics.html)’ or ‘Guidelines on good publication (http://www.publicationethics.org.uk/guidelines)’ can be applied.
CEO will consider manuscripts prepared in accordance with the “Uniform Requirements for Manuscripts Submitted to Biomedical Journals.” Authors are advised to read these guidelines, especially when deciding on who qualifies as an author.
- Format: Write in English with double line-spacing on one side of single A4 sheets with a margin of at least 2.5 cm on every side.
- Page Number: Number pages consecutively in the upper righthand corner, beginning with the title page.

Figures and tables should use conventional units, with conversion factors given in legends or footnotes. In accordance with the Uniform Requirements, however, manuscripts containing only SI units will not be returned for that reason.
- Drug Names: Generic names should be used. When proprietary brands are used in research, include the brand name and the name of the manufacturer in parentheses after the first mention of the generic name in the Methods section.
- Abbreviations: Except for units of measurement, abbreviations are strongly discouraged. Except for units of measurement, the first time an abbreviation appears, it should be preceded by the words for which it stands. Manuscripts containing research data, generally follow the order: Title page, Abstract, Text, Conflict of Interest, Acknowledgments, References, Tables, and Figure legends. Start each section at the top of a new page, and number all the pages.
- Highlight: All papers include 3-5 short highlights presenting short summary or findings in the next of title page: each highlight includes less than 90 characters including space.
This should contain the title of an article, full names of authors and institutional affiliation(s). If several authors, and institutions are listed, they should be clearly indicated with which department and institution each author is affiliated. In a separate paragraph, address for correspondence, including the name of corresponding author, degree, address (institutional affiliation, city, zip-code and country), telephone and fax numbers, and e-mail address) should be given.

Structured abstract & keywords
The abstract should be concise, less than 300 words, and describe concisely, in a paragraph. Use the following subheads: Objectives: State the objective or question addressed by the research. Any hypothesis should also be stated. Methods: Describe the basic experimental design of the study. The number of subjects and how they were selected should be provided. Results: State the main results of the study. Conclusions: State the conclusions of the study that are directly supported by the data, along with the clinical implications or applicability.
Abbreviations, if needed, should be kept to absolute minimum with proper identifications. But Abstracts for case report carry the same restrictions of word count. Abstract is not required for editorials or for correspondence.

Brief background, references to the most pertinent papers generally enough to inform readers, and relevant findings of others are described. The specific question to which the authors’ particular investigation is studied should be also described.
Materials and Methods
Explanation of the experimental methods should be concise and sufficient for repetition by other qualified investigators. Procedures that have been published previously should not be described in detail. However, new or significant modifications of previously published procedures need full descriptions. The sources of special chemicals or preparations should be given along with their location (name of company, city and state, and country). Method of statistical analyses and criteria of significance level should be described.
This part should be presented logically using text, table and illustrations. Excessive repetition of table or figure contents should be avoided.

Article Submission & Processing Charge
There is no submission fee. But article charges are required for publication in the Clinical & Experimental Otorhinolaryngology. These cover some of the costs of publication as well as open access online editions in the journal website (http://www.e-ceo.org) or in the PubMed Central (http://www.ncbi.nlm.nih.gov/pmc/journals/880/). Invoice will be sent to the corresponding author when the submitted article is finally accepted. The charge is USD 300 per article.
Editorial and Peer Review Process
If the manuscript does not fit the aims and scope of the Journal or does not adhere to the Instructions to authors, it may be returned to the author immediately after receipt and without a review. Before reviewing, all submitted manuscripts are inspected by Similarity Check powered by iThenticate (https://www.crossref.org/services/similarity-check/), a plagiarism-screening tool. If a too high a degree of similarity score is found, the Editorial Board will do a more profound content screening. The criterion for similarity rate for further screening is usually 15%; however, the excess amount of similarity in specific sentences may be also checked in every manuscript. The settings for Similarity Check screening are as follows: It excludes quotes, bibliography, small matches of 6 words, small sources of 1%, and the Methods section.
For peer-reviewing, one copy of the manuscript is reviewed for English. The remaining two manuscripts are sent to two most relevant investigators for review of the contents. The editor selects peer referees by recommendation of the Editorial Board members or from the specialist database owned by the Editorial Board.
If decided necessary, review for statistics may be additionally requested. For review, names and their affiliations of the authors are blinded.
Acceptance of the manuscript is decided, based on the critiques and recommended decision of the referees. A referee’s decision is made as “acceptance without revision”, “acceptance after minor revision”, “review after revision” and “rejection”. If there is marked discrepancy in the decisions between two referees or in opinions between the author and referee(s), the Editor may send the manuscript to another referee for additional comments and recommended decision. Three repeated decisions of “review after revision” are regarded as “rejection”. The reviewed manuscripts are returned back to the corresponding author with comments and recommended revisions. Names and decisions of the referees are masked. A final decision on acceptance or rejection for publication is forwarded to the corresponding author from the Editorial Office.
The usual reasons of rejection are insufficient originality, serious scientific flaws, poor quality of illustrations, or absence of a message that might be important to readers. The peer review process takes usually four to eight weeks after the manuscript submission.
Revisions are usually requested to take account of criticism and comments made by referees.
Failure to resubmit the revised manuscript within two months is regarded as a withdrawal. The corresponding author must indicate clearly what alterations have been made in response to the referees’ comments point by point. Acceptable reasons should be given for noncompliance with any recommendation of the referees.
