Responses to Reviewer 1

Reviewer point #1: Authors should report ethical committee approval with code and date of approval.

Author response #1: We added ethics committee approval with code 2023YX134 and an approval date of November 29, 2023. (Line 86-87)

Reviewer point #2: Why authors did not compare the lateral approach with the standard one? Please clarify.

Author response #2: When compared with the standard approach, the lateral approach undoubtedly results in longer procedural time and superior aesthetic outcomes. Therefore, the inclusion of such a comparison might make the study too broad, making it challenging to emphasize key points. The focus of this research is to highlight three pathways that progressively lengthen, step by step, gradually accumulating anatomical experience, with a short learning curve for clinicians. We chose to concentrate on a specific aspect to provide a more in-depth analysis.

Reviewer point #3:  "Of the 52 patients, 8 were male and 44 were female, with an age range of 31-50 years and a mean age of (41.75±9.27) years." This information should be provided in the results section.

Author response #3: This information is provided in the results section. (Line 120-126、Line 183-184)

Reviewer point #4: Where is Weifang People's Hospital located? Please specify.

Author response #4: The location of Weifang People's Hospital is provided in the Correspondence section of the manuscript. (Line 11-13)

Reviewer point #5: Please include the outcomes studied under the subparagraph "outcomes" in the methods section.

Author response #5: The results section contains the full study results, and the methods section contains the observational Indicators related to the results.

Reviewer point #6: In all the tables provided, rows and columns must be inverted, to increase readability.

Author response #6: We have inversion is made for the rows and columns.

Reviewer point #7: In table 3, 4 and 5 there are some characters in chinese. please remove them.

Author response #7: We remove the Chinese characters.

Reviewer point #8: Please report a paragraph with the limitations of the study.

Author response #8: We add the content about the limitations of this study. (Line 388-395)

- Describe surgical techniques in more granular steps rather than just approach name. Identify key steps like nerve monitoring, hemostasis methods.

- Specify equipment/instruments used like endoscopic system, energy devices, monitoring systems, operation table configuration.

- Explain outcome measures and how they were assessed - define variables clearly like blood loss (intra-op vs total), complications (grading system), satisfaction scales.

- Describe statistical analysis in more detail - what tests were used for which outcomes based on data type/distribution. Specify significance level.

Results:

- Provide summary stats for sample characteristics like mean/median values for age, tumor size rather than just ranges.

- Use tables to present results clearly for easy comparison between groups.

- Consider graphical displays like boxplots for non-normally distributed data.

Revision 2

Dear Editor and Reviewers,

Thank you very much for taking the time to review this manuscript amid your busy schedule. I sincerely appreciate all your comments and suggestions. Below, you will find my itemized responses, and in the resubmitted files, you can locate my revisions/corrections. We have submitted two versions of the manuscript, one with marked changes and the other without markings. Thanks again!

Responses to Reviewer 1

Reviewer point #1: The authors successfully addressed all the comments provided. I believe the manuscript is now ready for acceptance in its present form.

Author response #1: Appreciate your time and valuable input.

Responses to Reviewer 2

Methods:

Reviewer point #1: Provide more details on patient selection criteria, such as inclusion/exclusion criteria related to tumor stage, disease status, other medical conditions, etc.

Author response #1: The inclusion standards remain unchanged, while exclusion criteria have been added.(Line99-104)

Reviewer point #2: Describe surgical techniques in more granular steps rather than just approach name. Identify key steps like nerve monitoring, hemostasis methods.

Author response #2: Detailed steps for three lateral approach surgical procedures are described.(Line119-152)

Reviewer point #3: Specify equipment/instruments used like endoscopic system, energy devices, monitoring systems, operation table configuration.

Author response #3: The models and manufacturers of the instruments and equipment have been provided. (Line108-117)

Reviewer point #4: Explain outcome measures and how they were assessed - define variables clearly like blood loss (intra-op vs total), complications (grading system), satisfaction scales.

Author response #4: We have explicitly defined variables in the original text. For example, intraoperative blood loss is defined as the volume of bleeding during surgery, and postoperative drainage is defined as the amount of drainage following the operation. All observed complications were transient, and no severe complications occurred; therefore, no grading was performed. The transient nature is explicitly stated in the original text. Satisfaction comparison was assessed through postoperative follow-up scoring on a 5-point scale.(In the results section)

Reviewer point #5: Describe statistical analysis in more detail - what tests were used for which outcomes based on data type/distribution. Specify significance level.

Author response #5: Continuous data were presented as mean ± standard deviation (x±s). Analysis of variance (ANOVA) was used for normally distributed data, and non-parametric tests were used for data with non-uniform variances. Categorical data were presented as frequency (n) and percentage (%), and the chi-square test was used for intergroup comparisons. A p-value of less than 0.05 was considered statistically significant.(Line175-181)

Results:

Reviewer point #1: Provide summary stats for sample characteristics like mean/median values for age, tumor size rather than just ranges.

Author response #1: In Section 2.1.(Line186-196)

Reviewer point #2: Use tables to present results clearly for easy comparison between groups.

Author response #2: See Results section.

Reviewer point #3: Consider graphical displays like boxplots for non-normally distributed data.

Author response #3: The box plots have been added to the manuscript. (Line208-212、216-217)

Reviewer point #4: Conduct subgroup/stratified analysis where appropriate to identify effect modifiers.

Author response #4: Considering our research objectives, we believe that subgroup/stratified analysis would not be meaningful.

Reviewer point #5: Report both numerical values and percentages for categorical variables like complications.

Author response #5: Refer to Sections 2.3 and 2.5.

Reviewer point #6: Interpret statistically significant vs non-significant findings in the discussion.

Author response #6: Refer to the discussion section 3.1-3.4 for the analysis of the results section.

Reviewer point #7: Highlight key findings and discuss implications for clinical practice and further research.

Author response #7: Refer to lines 391-408.

Responses to Reviewer 3

Reviewer point #1: I think authors have addressed the questions raised by the previous reviewers. I have no further comments.

Author response #1: Appreciate your time and valuable input.

Open letter on the publication of peer review reports

PLOS recognizes the benefits of transparency in the peer review process. Therefore, we enable the publication of all of the content of peer review and author responses alongside final, published articles. Reviewers remain anonymous, unless they choose to reveal their names.

We encourage other journals to join us in this initiative. We hope that our action inspires the community, including researchers, research funders, and research institutions, to recognize the benefits of published peer review reports for all parts of the research system.
