A new transnasal approach of Nd:YAG laser treating nasolabial cysts.

This paper is to explore the effectiveness of a new modified transnasal endoscopic marsupialization through Nd:YAG (neodymium: yttrium-aluminum-garnet) laser in treating nasolabial cysts in office. A prospective study was undertaken. Patients who suffered from nasolabial cysts from April 2016 to May 2017 at our hospital were involved. They were all treated with Nd:YAG laser transnasal endoscopic marsupialization. All patients were treated in the outpatient treatment room under local anesthesia. The patients ranged in age from 27 to 82 years, with an average age of 45 years. We made the diagnosis by the anatomical site, radiological imagings, and histopathology of the cyst. A total of 12 consecutive patients (men, n = 2; women, n = 10) with nasolabial cysts were involved in this study. Of the 12 patients, 6 were on the left and 8 were on the right side, and 2 had bilateral nasolabial cysts. All patients returned to clinic at 1, 6, and 36 months after treatment. At the follow-up time, none of the patients has mucus accumulation in the sinus or cyst recurrence, except for one patient who received treatment twice. No complications and recurrence during follow-up. In this study, we find that transnasal endoscopic marsupialization through Nd:YAG laser in treating nasolabial cysts is relatively effective, especially for patients who do not want to be hospitalized or treated under general anesthesia.
