INTRODUCTION: Sutural bones or intersutural bones commonly known as Wormian bones are extra bone pieces that occur commonly within the sutures or at the fontanelles of the cranium. MATERIAL AND METHODS: The present study was conducted at the All India Institute of Medical Sciences, Patna. Thirty complete, dry adult human skulls were studied and examined for the presence or absence of sutural bones. Their number and the location along the cranial sutures and at the fontanelles were noted. To take cranial measurements for the cranial index, the skulls were oriented on a Frankfurt plane. RESULTS: The most common site where sutural bones were observed was at the lambdoid suture with the incidence of 61.2% of the sutural bones, while the second most common site was at the coronal sutures with 10.6% of the total sutural bones found. The dominant shape of the head in the present study population was dolichocephalic, observed in 46.6%. The mean number of sutural bones was found to be highest in the most common skull type (dolichocephalic) with values of 5.43 ± 5.1. CONCLUSIONS: Though the current study reports fewer sutural bones than in previous literature, given the high population density of the East Indian states, these presented mean values require special attention.

WSTĘP: Kostki szwów (kości wstawne lub śródszwowe), zwane kośćmi Worma, często występują w obrębie szwów lub ciemiączek czaszki, w obrębie desmocranium. MATERIAŁ I METODY: Badania przeprowadzono w Instytucie Nauk Medycznych w Patnie w Indiach. Zbadano 30 wysuszonych ludzkich dorosłych czaszek w celu stwierdzenia występowania lub braku kostek szwów. Określono ich liczbę oraz lokalizację w obrębie szwów i ciemiączek. Pomiarów czaszek dokonano w płaszczyźnie frankfurckiej (tj. płaszczyźnie poziomej przechodzącej przez dolny brzeg oczodołu i górny brzeg otworu słuchowego). WYNIKI: Najczęstszą lokalizacją kości szwów był szew węgłowy (sutura lambdoidea) – w 61,2% badanych czaszek, oraz szew wieńcowy (sutura coronalis) – w 10,6% badanych czaszek. Dominujący był typ długogłowy (długoczaszkowy – dolichocephalic, dolichocranium), występujący w 46,6% badanych czaszek. Średnia liczba kości szwów była największa w typie dolichocefalicznym – 5,43 ± 5,1. WNIOSKI: Obecne badania dotyczące kości szwów są niewielkie w porównaniu z badaniami we wcześniejszych publikacjach. Ze względu na dużą gęstość zaludnienia wschodnich stanów Indii prezentowane wyniki zasługują na uwagę.
