Abstract

Marsupialization is the conservative treatment for cystic lesion in children. This technique requires maintaining the patency between the cyst and oral cavity to allow spontaneous healing of cystic lesion. There have been various fixation methods for securing the patency. However, the previous fixation methods have limitation of being invasive and inability to retain catheter firmly during the treatment. In this technical note, we adopted a novel and easy fixation method to obtain firm stability of catheter without damage to intraoral tissues during marsupialization technique.

Introduction

Marsupialization is a type of conservative treatment for odontogenic cysts in growing children. This technique consists of opening the cystic cavity and maintaining the patency between the cyst and oral environment to allow spontaneous healing of cystic lesion [1], [2], [3], [4], [5]. This procedure can also promote eruption of cyst-involved teeth without harming vital structures around the cyst [3], [6], [7], [8].

To maintain patency through the bony window, secure fixation of catheter is the essential step during the treatment. Thus, several methods, such as suture or screw fixation, have been introduced. However, secure fixation still remains a challenge, since previous methods have limitation of being invasive or stability [9].

In this technical note, we represent a simple method to secure catheter easily in case of having difficulty in firm fixation due to anatomical reasons.

Case 1

A 9-year-boy was referred to our clinic with a chief complaint of swelling around the premaxilla. He had no systemic disease or relevant familial history. Clinically, bony swelling ranging from maxillary labial vestibule to hard palate and severe displacement of maxillary incisors were observed (Fig. 1). The panoramic radiograph and cone-beam CT images revealed a well-defined and heart-shaped radiolucent lesion around anterior region of maxilla (Fig. 1). The lesion was initially diagnosed as

Discussion

For the decrease in cystic pressure and periodic irrigation of cystic cavity, continuous drainage by keeping the patency through window is important in marsupialization. An ideal marsupialization catheter requires following requirements. It should allow firm attachment of catheter in position, easy fixation and easy daily cleansing. And it should not make any interference with daily mastication and should be hygienic [10].

In the present cases, we adopted new devices composed of a tooth-borne
