Ethmoidal hematoma in nine horses.

The research conducted a study on nine horses diagnosed with ethmoidal hematoma. This condition was diagnosed through physical examination, endoscopy, radiography, and histologic examination of tissues. After surgical treatment, there were some cases of recurrence observed over an average period of 61 months.

Diagnosis of Ethmoidal Hematoma

• The study focused on horses that were diagnosed with an ethmoidal hematoma.
• These diagnoses resulted from a combination of physical examinations, endoscopy procedures, radiography, and the histologic evaluation of tissue samples.
• The symptoms exhibited by these horses included stertorous (labored or noisy) breathing or intermittent nasal discharge that was sanguineous (mixed with blood).

Surgical Treatment

• All the diagnosed horses underwent surgical treatment: sinusotomy (an operation on the sinus) and extirpation (removal) of the lesion caused by the hematoma.

Post-Surgical Observation

• After surgery, the horses were reexamined over a span of 15 to 104 months, with the mean period being 61 months.
• Three of the horses were found to have a recurrence of the ethmoidal hematoma.
• In addition, one horse developed an ethmoidal hematoma on the ethmoturbinates located on the side opposite (contralateral) to the original hematoma.
• Moreover, one horse not only experienced a recurrence of the original hematoma but also developed a new contralateral lesion.
• Seeing these recurrences and new lesions, additional surgeries had to be performed.

Conclusion

• This study highlights the challenges in treating ethmoidal hematoma in horses, specifically the possibilities of recurrence and the formation of new lesions post-surgery.
