This study presents a novel conservative technique to increase oral opening and overcome rigor mortis during medicolegal autopsy (MLA). The method proposes a myotomy of the temporalis and masseter muscles, taking advantage of the incisions of the cranial opening procedures, to achieve a significant oral opening (≥ 30 mm) in fresh cadavers with established rigor mortis without altering facial aesthetics. The study was performed on 48 individuals aged between 18 and 66 years (20 males and 28 females) who were autopsied at the Instituto Nacional de Patología Forense Dr. Sergio Sarita Valdez (Santo Domingo, Dominican Republic). The proposed technique not only allowed the oral access to all autopsied cadavers but also complied with current ethical standards for preserving facial aesthetics, taking into account the concerns of family members by allowing respectful viewing of the cadaver. This advancement not only contributes to the efficiency of oral autopsies but also influences public perception of forensic procedures and highlights the importance of ethical and aesthetic considerations in the context of MLAs. The proposed technique represents a significant step towards more respectful and ethical forensic practices, and offers practical advantages for a more complete and accurate assessment during MLA.

这项研究提出了一种新颖的保守技术，可在法医学尸检（MLA）过程中增加口腔张开度并克服尸僵。该方法提出对颞肌和咬肌进行肌切开术，利用开颅手术的切口，在尸僵的新鲜尸体上实现显着的口腔开口（≥30毫米），而不改变面部美观。该研究对 48 名年龄在 18 岁至 66 岁之间的个体（20 名男性和 28 名女性）进行了尸检，这些人在国家病理研究所 Sergio Sarita Valdez 博士（多米尼加共和国圣多明各）进行了尸检。所提出的技术不仅允许对所有尸检尸体进行口腔接触，而且还符合当前保存面部美观的道德标准，通过允许尊重地观看尸体来考虑到家庭成员的担忧。这一进步不仅有助于提高口腔尸检的效率，而且还影响公众对法医程序的看法，并强调了在司法鉴定领域伦理和美学考虑的重要性。所提出的技术代表了朝着更加尊重和道德的法医实践迈出的重要一步，并为 MLA 期间更完整和准确的评估提供了实际优势。
