syndrome such as Apert syndrome, Crouzon syndrome
which can affect your baby’s skull development.

25. Craniosynostosis
• Types of Craniosynostosis
Metopic Synostosis: It occurs when there is a fusion
between sagittal strucrure and nose. Metopic synostosis
results in triangular development of scalp.
Lamdoid Synostosis: It is the rarest types of
craniosynostosis and affects the back portion of the
head.Lamdoid synostosis results in twisted shape of skull.

26. Craniosynostosis
Coronal craniosynostosis: It occurs when there is an
early fusion between the coronal structures of the skull,
which affects the higher eye socket and results in the flat
development of the forehead.

27. Metopic
craniosynostosis

30. Craniosynostosis
Etiology

injuries especially when associated with retention of
intraorbital foreign body and following operations like
orbitotomy, dacryocystectomy.
Extension of Infection: It occurs from neighbouring
structures which include paranasal sinuses, teeth,face,lid
intracranial cavity and intraorbital structures.

55. Orbital Cellulitis

Appear as a firm, round,localised lesion in the upper
temporal or upper nasal aspect of the orbit
These are located anterior to the orbital septum.

78. Developmental tumors
(b)Complicated Dermoid: These are present in adoloscence
with proptosis or a mass lesion.They may be associated
with bony defects.
Epidermoid: It is composed of epidermis without any
epidermal appendages in the wall of the cyst.the cyst
wall contain Keratin debris.
Lipodermoids: These are solid tumors usually seen
beneath the conjuctivaThese are mostly located adjacent
to the superior temporal quadrant of the globe.

79. Developmental tumors
• Teratomas: These are composed of ectoderm,mesoderm
• And endoderm.
• These may be solid,cystic or a mixture of both
• Most of these are benign but some solid tumors in
newborns are malignant
• Cystic tumors may b e excised without removing the eye
ball.

84. Cavernous Haemangioma: Also called as Cerebral
cavernous malformaton (CCM).It is a type of blood vessel
malformation where a collection of dialated blood
vessels form a benign tumor.
Because of these malformations blood
flow through the cavities or caverns is slow.
