Address   for   Correspondence:    Dr.   Tallapaneni   Sreekanth,   Associate   Professor,   Department   of   Anatomy,   Shadan   Institute   of   Medical   Sciences,   Teaching Hospital   &   Research   Center,   Peerancheeruvu,   Near   Arramaisamma   Temple,   Hyderabad,   Telangana,   India.   Mobile   No:   70934   49309,   91006   83056.   E-Mail: anatomysreekanth18@yahoo.com ABSTRACT Aims    and    Objective:    The    Wormian    bones/Sutural    bones    are    defined    as    those    accidental    or    intercalated    bones    found    among    the    sutures    of    the      neurocranium   having   no   regular   relation   to   their   normal   ossific   centers.   The   present   study   mainly   aims   at   the   number,   location   of   these   wormian   bones   in the   adult human skulls of Telangana. The knowledge of Sutural bones is essential for the radiologists and neuro surgeons in there clinical practice. Materials   and   Methods:   About   40   dry   human   skulls   were   collected   from   the         department   of   Anatomy.   71   dry   human   skulls   were   collected   from   the      MBBS Students.   Total   of   111   dry   adult   human   skulls   were   examined   meticulously   for   the   presence   of   wormian   bones.   In         respect   to   their      location   and   number. After the collection of the data it was tabulated and statistically analysed. Results:    According   to   the   present   study   the   incidence   of   wormian   bones   was   59   out   of   111   adult   skulls.   The   maximum   number      of   wormian   bones   at lambdoid   suture   59   [25   right,   34   left;   53.15%].   The   wormian   bones   were   also   seen   at   lambda   9   [8.10%],   Pterion   2[2   right,   0   left;   1.80%   ],   Asterion   3   [1   right, 2   left;   2.7.%],   Parieto   Temporal   suture   5[3   right,   2      left;   4.5%],   Occipitomastoid   suture   1   [0   right,   1   left;   0.90%],      sagittal   suture   1   [0.90%],   bregma   1   [0.90%].     In the present study  we could not find any wormian bones near Coronal suture. Conclusion:   The   present   study   proves   the   occurrence   of   wormian   bones      in   the   human   skulls   is   common   at   the   lambdoid   suture.   Also   they   may   occur   in combination   at   different   sites   and   at   different   sutures.   The   knowledge   of   their         existence      is   essential   to   the   radiologists   during   the   reporting   radiographs   in head injuries of skull  involving fractures  and neuro surgeons while performing craniotomies.
