1. Chronic suppurative otitis media (CSOM) can lead to both cranial (intratemporal) and extra-cranial complications. Cranial complications include mastoiditis, petrositis, labyrinthitis, facial paralysis, and perilymphatic fistula.
2. Intra-cranial complications occur when infections penetrate bony barriers and spread to the dura mater, arachnoid, or pia mater, causing epidural abscesses, subdural abscesses, meningitis, or brain abscesses. Lateral sinus thrombosis is a serious complication resulting from direct extension or via the mastoid emissary vein.

Granulomatous conditions in ENT are rare conditions that we come in contact with, we tend to overlook them because they are so rare, however some of the conditions like TB and syphillis and Mucormycosis of the Nose and PNS are seen in our clinics
this is a good summary from scotts brown chapter

Diseases of the external ear are common conditions to be encountered in ENT practice. This presentation is about the major conditions of pinna and EAC including pinna defects, pseudocyst of pinna, perichondritis, hematoma, pseudocyst of pinna, otitis externa, otomycosis, malignant otitis externa, keratosis obturans etc.
CSOM may lead to different complications. Although less common in developed countries, CSOM is common in developing and underdeveloped countries.
This presentation explains the complications of CSOM in details.

7. Pre-disposing factors
• Age
• Virulent organisms
• Cholesteatoma or Bone erosion
• Presence of a congenital dehiscence
• Obstruction of drainage e.g polyp
• Low resistance of the patient
• Poor socio-economic status
9. Pathways of infections
• The commonest way for extension of
infection is by bone erosion due to a
cholesteatoma.
• Vascular extension (retrograde
thrombophlebitis).
• Extension along preformed pathways as
– Congenital dehiscences, fracture lines, round
window membrane, the labyrinth,
– Dehiscences due to previous surgery.
28. Lateral Sinus Thrombosis (sigmoid sinus)
Spread of infection by direct extension or
via mastoid emissary vein

31. LST ……Treatment
• Empiric broad coverage until C&S
• antibiotic with good CSF penetration
• Surgery
– Mastoidectomy
– Decompression
– Thrombus evacuation
32. Intracranial Epidural Abscess
• Localized between dura
and bone
• dural adherence to bone
at suture lines
• Focal osteomyelitis
• Management and
etiology same as
subdural empyema
33. Subdural Abscess
• Between the dura and
the arachnoid.
• Potential space
• Lack of anatomical
boundaries
→ spread rapidly
• Ear 14%
• (paranasal sinusitis
75%)
