Diagnosis and Surgical Treatment of Idiopathic Primary Sino-Nasal Obstruction in Miniature Horse Breeds: Long-Term Follow-Up of Seven Cases.
Abstract: Idiopathic sino-nasal obstruction resulting in retention of large amounts of liquid in the paranasal sinus compartments was diagnosed in seven young (2. 2 ± 0.7 years) miniature-breed horses based on clinical, endoscopic, radiographic, and CT scan examinations. The most prevalent clinical signs included decreased or no airflow from the nostril(s) (7/7) and nasal discharge (6/7). The problem presented bilaterally in six of seven cases. An alternative sino-nasal communication was created through bone flap osteotomy surgery and perforation of the ventromedial floor of the dorsal conchae in all cases, followed by fixation of silicone irrigation tubes/Foley catheters in six of seven cases to keep the newly created ostium patent. This resulted in long-term resolution of the problem with good cosmetic appearance in all animals following a median period of 19 months. Premature loss of fixed tubes was reported in three cases.

This research discusses the diagnostic process and surgical treatment for a condition causing sinus obstruction in young miniature-breed horses, including a long-term follow up on seven such cases.
Overview of the Research
- The research paper looks at a specific veterinary condition called idiopathic sino-nasal obstruction that affects young miniature horse breeds.
- The term “idiopathic” refers to a disorder or condition with no known cause. In this case, the obstruction is causing large amounts of liquid to be retained in the horses’ paranasal sinus compartments, which are the air spaces within the bones around the nasal passages.
Diagnosis and Clinical Signs
- The diagnosis of this condition was made in seven young miniature-breed horses (around 2.2 years old), through a combination of clinical, endoscopic, radiographic, and CT scan examinations.
- The prevalent clinical manifestations included a decrease or lack of airflow from the horses’ nostrils and nasal discharge. The sinus blockage was present in both nostrils in six out of the seven cases.
Surgical Treatment
- An alternative communication between the sinus and the nasal passage was created via bone flap osteotomy surgery. The procedure involved removing a piece of bone to allow the fluid to drain. Additionally, a hole was perforated in the ventromedial floor of the dorsal conchae, which is a specific part of the nasal structure.
- In six out of the seven cases, silicone irrigation tubes or Foley catheters were inserted to keep the newly created opening clear. The insertion of these tubes helps prevent the opening from becoming obstructed again.
Outcomes and Follow-Up
- According to the research, the surgical treatment resulted in a long-term resolution of the problem in all seven horses, which was monitored over a median period of 19 months. Additionally, the cosmetic appearance of the horses was satisfactory after the procedure.
- However, the report noted that in three cases, the tubes became dislodged prematurely. This indicates that there could be some complications with the procedure relating to the durability of the inserted tubes.
