Decompression of Odontogenic Cysts Using an Appliance Fabricated With a Fully Digital Workflow

Summary

The aim of this prospective case series is to present clinical results with cystostomy, decompression and final enucleation of odontogenic cysts using a decompression device fabricated with a full digital workflow and delivered on the day of cystostomy. The secondary purpose of our study is to present the volumetric changes of the odontogenic cysts treated by decompression.

Conditions

• Odontogenic Cysts

Interventions

DIAGNOSTIC_TEST

Preoperative Cone Beam Computed Tomography (CBCT) scan

CBCT scans (Green X, Vatech, Hwaseong, Korea) are carried out prior to cystostomies. The scanning conditions are constant at 200 µm isotropic voxel size with 360° rotation, 94 kV tube voltage, 7.2 mA tube current and 9 s exposure time with a 15 × 8 cm field of view field of view (FOV).

PROCEDURE

tooth removal and cystostomy

Surgical interventions are carried out in local anaesthesia. If it is deemed that a tooth or teeth included in the odontogenic cyst is of hopeless prognosis, it is removed at the time of cystostomy procedure. During cystostomy a bony window is created to accessthe cyst. The lining of the cyst is opened to accomodate the tube of the decompression appliance. A sample from the lining of the cyst is sent for histologic evaluation to confirm the diagnosis of odontogenic cyst.

PROCEDURE

Decompression

The decompression appliances is delivered in the same sitting as the cystostomy. Patients are instructed on how to wear and clean their decompression device and are recalled for clinical examinations.

DIAGNOSTIC_TEST

Postoperative Cone Beam Computed Tomography (CBCT) scan

Postoperative CBCT examination is performed six months into the decompression period using the same scanning conditions as those used for the preoperative CBCT scan.

PROCEDURE

Cyst Enucleation

Following the decompression period enucleation of the remaining cyst is carried out in local anaesthesia.
