Endoscope‐assisted intraoral resection of external dermoid cyst

Abstract

Resection of the submental type dermoid cyst can be performed by an intraoral endoscope-assisted approach through the floor of the mouth. We describe the procedure of the endoscope-assisted intraoral resection.

Intraoral Removal of a Thyroglossal Duct Cyst Using a Frenotomy Incision

“…On the other hand, in our case, the risk of damage was relatively low because we used anatomical dehiscence through frenotomy incision. Previously, Kim et al published a paper about the safe excision of a dermoid cyst in the mouth floor through the frenotomy incision and discussed the potential application of this method to TGDC (13).…”

“…Depending on the location of the TGDC, various surgical resection methods have been reported. There have been several reports of a TGDC located in the base of the tongue or larynx, which have been treated through transoral endoscopic surgery (13). However, these methods have a possibility of damage of the mouth floor structure.…”

“…This technique became technically feasible with the advancements in endoscope system and ultrasonic scissors (harmonic scalpel) (9). This approach passes through the midline incision in the floor of the mouth and uses the natural midline dehiscence present between the genioglossus muscles (13). This area has been shown to be a relatively avascular dissection plane.…”

“…However, this operation requires a transcervical approach, which results in an external neck scar (13). Depending on the location of the TGDC, various surgical resection methods have been reported.…”

“…The transoral approach is relatively easy and it also has the advantage of minimizing trauma associated with access and seems to allow improved preservation of adjacent structures (13). The surgery is made feasible by the development of the endoscope and other medical instrument technologies.…”
