The so-called gummy smile is a smile with an excessive gingival exposure of the labial maxillary region.
The newly devised method described by Miskinyar was applied in the case of a girl aged 12. This method is a myectomy and partial resection of the levators labii superioris. It seems that the cause of gummy smile was the hyperactivity of the levators labii superioris in this case. 1 year and 5 months after the operation, her smile was very attractive and pleasing to her and the surgeon.
We concluded that the method described by Miskinyar was useful and safe.
