“…The consistency of the AB measurements evaluated in the dissection and tomography analyses confirms the hypothesis of a regular distance between the posterior wall of the maxillary sinus and the skull base observed in surgical practice and in two studies performed on cadavers 12 and CT scans, however with a difference of 0.5 cm between them. The new research with the same measurements on CT scans and on cadavers showed that they were > 1.5 cm in all cases evaluated.…”

“…11 Knowing the anatomical references and fixed measurements with almost no variation in terms of gender, race, age, weight, and height might provide surgeons more reliability, minimizing complications and optimizing interventions in the nasal sinuses. 12 The hypothesis of a regular distance, greater than 1.5 cm, between the posterior wall of the maxillary sinus and the skull base has been presented in a research with 120 nasal cavities of cadavers. 12 The purpose of the present research was to measure and compare the distance from the posterior wall of the maxillary sinus to the anterior skull base in cadavers and on CT scans to determine a measurement as an anatomical reference in imaging exams to assist the surgeon in endoscopic nasal surgeries.…”

Introduction Diseases of the paranasal sinuses, nasal cavities, and those related to the skull base can be treated with nasal endoscopic surgery. Anatomical references are essential to safely perform these surgeries. Objective To measure and compare the distance from the posterior wall of the maxillary sinus to the anterior skull base in cadavers and on computed tomography (CT) scans to determine a measurement as an anatomical reference in imaging exams for sinus and anterior skull base surgery. Methods In dissections and CT scans, we took measurements from the most upper and medial point of the posterior wall of the maxillary sinus (point A) to the point where the skull base deflects and the anterior sphenoid wall is formed (Δ 90°; point B), in the right and left nasal cavities. We used 51 cadavers aged ≥ 18 years in the present research. Results The measurements obtained from CT scans and dissections were greater than 1.5 cm in all cadavers, and they were positively correlated. The 1-cm increase in the AB-tomography measurement corresponded to the 1.08-cm increase to the right and 1.07-cm to the left in the AB-dissection measurement. Conclusion The CT measurements may be considered a reliable tool to promote safe and effective access to the paranasal sinuses, matching the distance that should be dissected until the anterior base of the skull.

“…Examination of this area of the body is particularly important in the case of death due to sepsis or inflammation of unknown origin, so it cannot be omitted in the case of post-mortem diagnostics [ 69 , 70 ]. The cranial sinuses may also be subject to post-mortem endoscopic evaluation, which has an important diagnostic value in the case of drownings [ 71 , 72 ]. Moreover, penetration of the endoscope into the sinuses also allows for indirect assessment of damage to the skull base [ 71 ].…”

The noticeable decline in the number of autopsies performed in recent years requires investigation into the causes of the phenomenon and attempts to prevent it. One potential cause of this trend is fear of disfiguring the body. Carrying out autopsies using a minimally invasive method may reduce the decrease in the number of autopsies performed. The first work on the development of the method and its continuation gave promising results. This allows us to start a discussion on attempts to introduce the method. The solution seems especially justified when the alternative is to completely abandon post-mortem examinations using the traditional method. Laparoscopy and thoracoscopy are tools that allow for accurate imaging and analysis of organ changes. Enriching them with additional tests using endoscopic techniques may have a positive impact on the accuracy of autopsy diagnoses. The development of a clear protocol for minimally invasive post-mortem diagnosis requires further research to determine the accuracy of the method.

In light of falling global autopsy rates, one of the causes of which is the resulting body disfigurement, it has become crucial to search for new, minimally invasive post-mortem diagnostic tools. One of these methods is videoautopsy, a minimally invasive autopsy technique using endoscopic methods. In the years 2020–2023, 15 videoautopsies were conducted at the Department of Forensic Medicine of the Poznan University of Medical Sciences in order to determine the usefulness of the method in forensic approaches. Each post-mortem examination included laparoscopy and thoracoscopy, followed by a classic autopsy to assess the effectiveness of the method. In total, the endoscopic examination allowed for determining the cause of death in 53.3% of cases, and when the cause of death was located in the abdominal cavity or chest, the percentage increased to 80%. Traumatic lesions had good recognition efficiency. In addition, it was also possible to collect material for histopathological and toxicological tests. Retroperitoneal organs were difficult to assess. The main limitation of the method is the inability to assess the inside of the skull and the structures of the central nervous system. Videoautopsy may become an important tool in post-mortem diagnostics and in forensic cases, especially when the alternative is to not perform an autopsy. Further research is necessary to standardise the examination protocol, optimise the instrumentation, and assess the potential synergistic effect with other methods of minimally and non-invasive post-mortem examination.
