An alternative technique for removal of an epidermal inclusion cyst (i.e. atheroma or epidermoid cyst) that does not require meticulous dissection or daily treatment to sclerose the cyst lining is reviewed. The technique is performed after anaesthesia of the infraorbital nerve and surgical preparation of the false nostril. A 1-cm stab incision is made into the ventral aspect of the cyst and its contents are expressed into the cavity of the false nostril. A laryngeal burr is inserted into the lumen of the cyst and rotated to engage the cyst lining in the tines of the burr. The burr is retracted, everting the cyst lining, which is then excised. This technique was used to remove epidermal inclusion cysts of the false nostril of 8 horses.
