Video otoscopy-assisted Holmium: yttrium-aluminum- garnet laser excision of aural masses in four dogs.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: This case series reports the outcomes of four dogs that underwent video otoscopy-assisted laser excision (VALE) of aural masses using a Holmium: yttrium-aluminum-garnet (Ho:YAG) laser. Case Description: All cases underwent excision of aural masses by snare polypectomy and laser ablation of the stalk or direct excision of the mass with a Ho:YAG laser. The first three cases underwent VALE and were free of clinical signs at follow-up times ranging from 197 to 403 days post procedure. In one case, the direct application of the laser on the mass resulted in thermal necrosis of the submitted tissue and an open histopathological diagnosis. In the fourth case, VALE was unsuccessful due to an intimate adhesion of the mass with the tympanic bulla. This patient underwent total ear canal ablation and lateral bulla osteotomy (TECALBO), which subsequently developed a deep surgical site infection and was revised. The patient experienced complete recovery at 232 days post TECALBO. Conclusion: VALE of aural masses using a Ho:YAG laser is a minimally invasive and effective treatment for aural masses in dogs in the medium term, providing an alternative to TECALBO in three out of four of our cases. Direct excision of the mass using a laser can cause thermal necrosis of the tissue, making histopathologic diagnosis more challenging. More studies are required to determine the contraindications of this technique and to better quantify the outcomes and complications.
