A modified intranasal endoscopic excision for nasal vestibular cyst in China

This study aimed to improve the surgical removal procedure for nasal vestibular cysts. Twenty-three patients with nasal vestibular cysts underwent surgical removal of the cyst via a transoral sublabial approach and another 30 patients via a modified intranasal endoscopic excision method. The 30 patients were treated with local anesthesia and the roof of the cyst, which was firmly attached to the mucous membrane of the anterior floor of the nasal cavity, was removed transnasally with microdebrider. Bleeding of the opening was stopped by electric coagulation without nasal packing. Among the 30 consecutive patients who underwent the modified surgical procedure, all patients were successfully treated. The mean duration of surgery was 5.7 ± 2.6 min. The mean estimated blood loss was 3.5 ± 2.1 ml. All patients were outpatients. The mean hospital stay was 1 h. The mean total cost was €140. The visual analog scale scores of postoperative pain, pressure and nasal obstruction were 1, 0 and 1, respectively. The incidence rate of postoperative lip swelling or numbness was 0 %. Postoperative endoscopic findings revealed that the cyst was replaced by an air-containing sinus with a persistent opening at the anterolateral nasal floor. There was no recurrence during a mean follow-up of 18 months. The modified intranasal endoscopic excision is a simple, less invasive, low-cost and effective surgical procedure for the treatment of nasal vestibular cysts. It might change the pattern of treatment for nasal vestibular cysts in China.
