Equine paranasal sinus disease: A long‐term study of 200 cases (1997–2009): Ancillary diagnostic findings and involvement of the various sinus compartments

Abstract

Nasal endoscopy, sinoscopy and skull radiography are of great value in diagnosing the presence and causes of equine sinus disease.

A Single Caudally Based Frontonasal Bone Flap for Treatment of Bilateral Mucocele in the Paranasal Sinuses of an American Miniature Horse

“…Although mucocele is rarely diagnosed in horses, [9][10][11][12][13] a unilateral mucocele in the paranasal sinuses was reported in a 2-year-old Thoroughbred filly that was successfully treated with sinus trephination and lavage. 18 The most likely cause of this condition is congenital or acquired occlusion of the nasomaxillary aperture.…”

“…9,10 In a more recent report of 200 horses with paranasal sinus disease, 9 horses had bilateral disease (3 primary sinusitis, 1 progressive ethmoid hematoma, 1 sinus cyst that eroded the nasal septum, 2 sinus neoplasia, and 2 traumatic sinusitis). [11][12][13] Although rare, bilateral sinonasal disease has been described in case reports [9][10][11][12][13][14][15][16][17] and may require bilateral paranasal sinus surgery for complete resolution of the disease. Severe cases of bilateral sinonasal disease causing deformation of the conchal sinuses or extension into the nasal cavity can obstruct air flow sufficiently to necessitate placement of a tracheotomy tube.…”

Clinical pharmacology of the respiratory system

“…Care must be taken to ensure that the cribriform plate is intact before performing chemical ablation to avoid accidental migration of formalin to the brain, as has been reported [68,69]. It is often necessary to repeat the injection every 3-4 weeks for two to four repetitions.…”

Peripheral nerve sheath tumour of the equine maxillary sinus

“…In one study the incidence of paranasal sinus tumours in horses suffering from sinonasal disorders was 5–7.9% (Tremaine and Dixon, ; Dixon et al . ). The majority of these tumours have been reported in mature horses (Head and Dixon ) and neither a breed nor sex predisposition has been observed (Tremaine and Dixon, ).…”
