Q: Is the goal explicitly stated in the Introduction? Is its formulation clear and unambiguous?
Comments: The goal is not explicitly stated in the Introduction, but it can be inferred from the context. The Introduction briefly discusses the challenges of nerve reconstruction in cases of mandibular tumorectomy and the potential benefits of using a nerve conduit, like the polyglycolic acid-collagen (PGA) tube, in these cases.
However, the formulation could be improved by clearly stating the goal of the study. For example, the authors could add a sentence like, "The goal of this case report is to demonstrate the potential benefits of using NERBRIDGE®, a polyglycolic acid-collagen (PGA) tube, for nerve regeneration following tumor resection in the inferior alveolar nerve." This would make the goal clear and unambiguous for the readers.
Q: Is the paper's structure coherent? Is it in coherence with the goal of the paper?
Comments: Yes, the paper's structure is coherent and is in coherence with the goal of the paper. The paper follows a clear structure that is commonly used in case reports:
Introduction: The Introduction provides a background on the challenges of nerve reconstruction following mandibular tumorectomy and the potential use of a nerve conduit, like the polyglycolic acid-collagen (PGA) tube, in these cases.
Case report: This section describes the case of a 35-year-old female patient with a peripheral nerve tumor in the inferior alveolar nerve, the surgical procedure followed, and the use of the PGA tube (NERBRIDGE®) for nerve reconstruction.
Discussion: In the Discussion section, the authors compare their findings with previous studies, discuss the advantages of using NERBRIDGE® over traditional autologous nerve grafting, and highlight the sensory recovery observed in their patient.
The structure of the paper effectively supports the goal of demonstrating the potential benefits of using NERBRIDGE® for nerve regeneration following tumor resection in the inferior alveolar nerve.
Tools and Methods
Q: Are methods the author uses adequate and well used?
Comments: Yes, the methods used by the author are adequate and well used for a case report. The author provides a detailed description of the clinical presentation, diagnostic process, surgical procedure, and postoperative follow-up for the patient:
Diagnostic process: The author outlines the initial examination, panoramic radiography, computed tomography, and magnetic resonance imaging used to diagnose the patient and plan the surgical procedure.

Q: Is the length of the paper adequate to the significance of the topic? Do you suggest shortening the paper without losing its value?
Comments: The length of the paper seems to be adequate for a case report on this topic. The paper provides sufficient information on the background, clinical presentation, surgical procedure, and follow-up of the patient. It also includes a discussion on the advantages of using NERBRIDGE® over traditional nerve grafting methods and the significance of the findings in the context of existing literature.
As a case report, the paper's primary goal is to present a unique case and its implications for future research or clinical practice. The current length of the paper allows for a clear and comprehensive presentation of the case without being overly long or repetitive.
It is not recommended to shorten the paper, as the current length and structure provide the necessary details to effectively convey the case and its significance. Reducing the length could potentially remove important information and compromise the value of the case report.
Figures & Tables
Q: Does the author use them suitably? Are legend and notations clear?
A: The author includes seven figures in the case report to visually illustrate the surgical procedure and the use of NERBRIDGE® for nerve reconstruction. These figures are suitably used to complement the text and help the reader better understand the surgical technique and the intraoperative findings.
The legends and notations for the figures are mostly clear and provide adequate descriptions of the images. However, some minor improvements could be made to enhance their clarity:
1. Ensure that all terms used in the legends are defined in the main text or the legend itself, such as "target sign" in the Introduction.
2. In the legends, consider using complete sentences for consistency and better readability.
