: As this study involves case reports on the application of a new technique, rather than a clinical trial, it is not subject to clinical trial registration requirements. The technique employed in these cases is a novel approach, and its application was thoroughly reviewed and approved by the Ethics Committee of the Affiliated Hospital of Guangdong Medical University with the approval number YLXJSHL2023-073. According to the Medical Quality Management Measures of the National Health Commission, the Declaration of Helsinki of the World Medical Association and the requirements of relevant laws and regulations, the ethical review and approval process was not influenced by any organization or individual. Before the study began, participants were given a detailed understanding of the study’s purpose, procedures, possible risks and benefits, and provided their written informed consent through signing consent forms.

: We have obtained written consent from the guardians of all patients for the publication of these case reports. Due to the patients’ advanced age and limited understanding of the publication-related issues, they requested that their guardians participate in the discussions and provide signed consent on their behalf. Prior to signing the consent form, both the patient and their guardian were thoroughly informed about the purpose, procedures, potential risks, and benefits of the study. After fully understanding this information, the patients were able to repeat the content of the consent form, demonstrating their comprehension of the study and related matters. Based on this understanding, the patients requested their guardians to sign the publication consent on their behalf. After confirming the patients’ wishes and fully understanding the relevant information, the guardians voluntarily signed the informed consent form, ensuring that all procedures adhered to ethical and legal requirements.
