Ingrowing horn

• Cause: ingrowing horn is a condition which may result either from damage to the horn corium or can occur in otherwise “normally” grown horns.
• Signs: horn is abnormally deviated towards the animal's soft tissues.  Left untreated, this results in the penetration of the horn into skin, underlying dermis and occasionally temporal bone damage. Areas involved are above the eye or on the temporal plate on the affected side.
• Diagnosis: visual examination.
• Treatment: surgical treatment is required.
• Prognosis: generally good.

Cost considerations

• Surgery cost is usually moderate, but further costs might derive from miasis prevention and antibiotic treatment. 

Special risks

• Frontal sinus empyema and sinusitis may occur - as a result of "opening" the sinus, when horn is amputated.
