The evaluation of frontal sinus similarity is one way to detect biological relationships, especially in small groups, including families of historically known personalities. However, possibilities for studying this issue are currently limited. This contribution deals with the frontal sinuses of a rare osteological sample with known genealogical data, members of the noble Swéerts-Sporck family from the 17th to 20th centuries. The aim is to verify whether the frontal sinuses reflect documented family relationships. Basic dimensions of the frontal sinus such as total surface area and volume, and maximum height and width, and also morphology and anatomical features were evaluated using computed tomography scans. The portions of the frontal sinus above the "external supraorbital line" were analyzed. The degree of similarity between biologically related individuals was determined for each variable and compared with their known biological distance. The degree of similarity based on dimensions was evaluated using both the unadjusted measured data and standardized data adjusted to size. For the unadjusted dimensions, a positive correlation between morphological similarity and biological relatedness was apparent. On the other hand, no positive correlation was apparent for most of the standardized data. Only total volume showed a very weak indication of a positive trend in the standardized data, but this was weaker than in the original values. A positive quantifiable relationship between morphological patterns and biological distance is not clearly indicated. However, nonmetric features do support the documented relationships of the individuals.

OBJECTIVE: To determine the degree of similarity of biologically related individuals according to the occurrence of skeletal developmental anomalies (SDA), to see whether these anomalies reflect documented biological relationships. MATERIAL AND METHODS: The sample consists of the skeletal remains of seven members of the noble Swéerts-Sporck family from the 17th-20th centuries. Eighty-nine SDA were examined using morphological assessment, X-ray and CT. The degree of similarity was calculated using a similarity coefficient (Cvrček et al., 2018). RESULTS: There were three shared SDA in the sample (cranial shift at the C-T border, cervical ribs, hypoplasia of rib 12), and another fifteen individual SDA were reported. The degree of similarity between individuals supports their documented relationships. The greatest similarity was found in closely related individuals such as father/son or siblings, and the least between unrelated individuals. CONCLUSIONS: SDA can be used as a supportive tool for detecting family relationships. The results correspond to the conclusions of earlier analyses of non-metric traits and frontal sinuses in the same sample: the smaller the biological distance between individuals, the greater the degree of their similarity. SIGNIFICANCE: Using unique human skeletal collections, this communication contributes to the expansion of knowledge about the familial occurrence of SDA. LIMITATIONS: The small number of individuals limits the use of statistical approaches. SUGGESTIONS FOR FURTHER RESEARCH: The results call for research on this topic using a larger sample with known genealogical data and the same approaches, to confirm our conclusions.

Frontal sinus analysis has potential utility for detecting biologically related individuals. However, the methodological approach to its evaluation, as well as its informative value, have been questioned. The aim of this work is to introduce a new approach to evaluating the frontal sinus using the 'external supraorbital line' (ESOL) and to determine whether there are sex differences within families in frontal sinus measurements and whether frontal sinus similarity reflects known genetic relationships in both measurements and morphology. We examined the skeletal remains of 41 adult individuals (25 males, 16 females), all members of one family over four generations (19th to 20th centuries), including individuals with very close consanguinity. CT images of skulls were acquired, and both the dimensions and morphology of the frontal sinuses were analyzed using their portions above the ESOL. No significant sex differences were found within families based on frontal sinus dimensions. Significant relationships were found between biological distance and the maximum height and morphology of the frontal sinuses. The greatest degree of similarity was found among closely related individuals. Additionally, in several cases, there was a greater degree of similarity between first cousins or grandparents and their grandchildren than among siblings or parents and their children. Total surface, volume and width are not significant indicators of relatedness. Known genetic relationships are also supported by individual morphological features. Variability within families with very close consanguineous relationships was lower than within families with common degrees of consanguinity, although differences are significant only for some variables.

Poúrazovou deformaci přední stěny frontální sinu můžeme řešit různými způsoby. Běžnou metodou je využití některého typu implantátu. V našem případě jsme provedli osteotomii a následnou repozici fragmentů do anatomického postavení. K fixaci jsme použili titanové minidlahy a šrouby. Uvedená kazuistika ukazuje na možné využití této metody u pacientů s rozsáhlejší čelní dutinou a výraznou poúrazovou deformací. V literatuře jsme nenalezli obdobný případ řešený popsaným způsobem.

Post-traumatic deformity of frontal sinus anterior table can be treated in various ways. Usage of a certain type of an implant is a common method. We performed an osteotomy and subsequent reduction of the fragments to reconstruct their anatomical position. Titanium miniplates and screws were used for fixation. This case report suggests a possible use of this method in patients with more extensive frontal sinus and distinct post-traumatic deformity. No similar case manages as described in our case report was found in the literature.

OBJECTIVE: Visualization by Draf I-III endoscopic access to the frontal sinus via drainage pathways is sometimes inadequate. We compare lateral frontal sinus exposures by Draf approaches versus our modification of removing the medial-superior wall of the orbit while preserving the periorbita. METHODS: Twenty cadaveric heads dissected using Draf IIB, III, and modified Draf III with medial and superior orbital decompression (MSOD) underwent thin-cut computed tomography (CT) scanning. Under image guidance, measurements extended from the midline crista gali to the most lateral point of the frontal sinus. A case report shows the modified Draf III improved frontal sinus access. RESULTS: Comparing Draf IIB and III with Draf III with MSOD, respectively, distances between midline and most lateral point averaged 19.1 mm, 23.7 mm, and 30.4 mm (left) and 18.7 mm, 25.1 mm, and 32.2 mm (right). Differences between Draf III with/without MSOD were 6.65 mm (left) and 7.09 mm (right); 12 heads were excluded because of under-pneumatization of the sinuses. CONCLUSIONS: Draf III with MSOD extended surgical access to lateral regions of the frontal sinus. This extension achieved better visualization and instrumentation with minimal removal of the frontal bone's orbital segment anterior and superior to the anterior ethmoidal artery while preserving the periorbita.

Oncocytic Schneiderian papilloma (OSP) is one of the three morphologically distinct tumors that arise from Schneiderian membrane (the others include exophytic papilloma and inverted papilloma). OSP almost always occurs unilaterally in the paranasal sinuses, usually in the maxillary sinus, ethmoid cells or sphenoid sinus. We report a case of a 64-year-old woman with OSP arising from the left frontal sinus. In the report herein, we describe an OSP originating in the region of frontal sinus, which, to the best of our knowledge, represents the first documented example in English literature of OSP developing in this anatomical site.
