Combined endoscope and low-temperature plasma knife for bilateral nasal vestibular cyst with sinus tract formation.

Compared to unilateral lesions, bilateral nasal vestibular cysts are more likely to be underdiagnosed due to the deceptive nature of the bilateral anatomy observed from the radiological findings. With this rare clinical case reported in this study, we hope our experience in diagnosis and treatment will provide a reference for otolaryngologist surgeons managing similar patients.
