decompression for jaw cystic lesions is an effective treatment , especially when the size of the lesion is large , such that complete removal may be difficult , or when it would be proximal to vital structures such as the inferior alveolar neurovascular bundle , maxillary sinus , or inferior border of the mandible[14 ] . this technique minimizes the size of the cystic lesions by reducing its osmotic pressure , favors the formation of new bone tissue , and causes fewer complications than enucleation , curettage , and resection . for successful decompression treatment , maintenance of a surgical opening between the cavity of the lesion and the oral environment is required[1,68 ] . numerous devices and adaptation methods were suggested and successfully used for maintaining the opening during decompression . the common materials used for making decompression devices are acrylic stents , nasopharyngeal airways , polyethylene tubes , nasal cannula , luer syringes , and polyethylene intravenous tubes . however , most techniques are associated with some problems and complications including long - term follow - up , soft tissue trauma , malpositioning of the tube , inappropriate tube size , loosening of sutures , mastication interference , and difficult oral hygiene . the aim of this technical report is to present a new effective decompression tube and securing method for treatment of cystic lesions in the jaw . we use a stainless tube and a 0.25 mm orthodontic ligature wire for our decompression device . the tube has an outer diameter of 3.0 mm and an inner diameter of 2.5 mm . the ideal tube length is determined by radiographic examination such as cone beam computed tomography and panoramic radiography . we make a loop from one end of a stainless steel wire on the top part of the tube that will be exposed in the oral cavity , and coil the other part of the wire around the tube . the wire is soldered to the tube using a torch and silver solder for adaptation of the loop and a funnel - like shape of this part of the device . the soldered part is trimmed , smoothed , and polished to a shape that impedes displacement of the device into the lumen of the cystic lesion ( fig . is performed at decompression , and the device is inserted into the cyst cavity for continuity between the cavity and the oral environment and daily irrigation of the cyst during decompression . a ligature wire is passed through the loop on the upper part of the device , and the tube is secured with the wire around the cemento - enamel junctions of the adjacent tooth in the pathologic area ( fig . we instruct patients about how to irrigate the cavity with a syringe during the long treatment period . when necessary , the tube length can be adjusted if the bone cavity decreases in size . several decompression devices and securing methods of the devices for cystic lesions in the jaw are described in the literature . tolstunov suggested five ideal characteristics for decompression devices : a design that prevents the device from falling into the bone cavity or dropping out at the end of the procedure ; does not interfere with daily mastication ; easily fixed to the soft tissue through sutures ; easy to clean the cystic cavity daily by the patient or staff ; and hygienic , not accumulating food particles over the time of its function . catunda et al . described some additional criteria including a shape for retention , easy adaptation and removal , smooth surface to impede food and allow easy cleaning , low cost , easy irrigation of cavity , and easy visualization during radiographic examination . the decompression tube using a stainless steel tube and wire fulfills these characteristics and possesses the following advantages : 1 ) radiopacity of the device allows estimation of the length , size , and position within the cavity . thus , clinicians can determine easily the timing of length adjustment , reposition , or removal of the device ; 2 ) because of smooth surface and texture , accumulation of food and plaque is impeded and cleaning is easy ; 3 ) a funnel shape of the upper part positioned above the gingiva prevents the device from falling into the cavity ; 4 ) when secured by wiring through a loop , the device allows some mobility so clinic staff can control a degree of device mobility as required from rigid to movable state . when the device is inserted into the cystic lesion , clinicians can not always center it in the cavity ( fig . if the device is firmly anchored , it may be obstructed by the regenerated tissues in the margin of the cavity as the bone regenerates during decompression ( fig . also , patients can carry out daily self - irrigation more easily due to the mobility ; 5 ) because it is secured with an 0.25 mm orthodontic ligature wire , the device can be installed under local anesthesia and eliminated or adjusted without any anesthesia . also , due to the thinness of orthodontic ligature wire , with a proper tooth brush instrument , an anchor tooth can avoid gingivitis . furthermore , this device can be easily set or detached from the tooth for adjustment or repositioning or cleansing ; 6 ) this decompression technique is not traumatic to surrounding soft tissue from sutures ; 7 ) it is relatively cheap and does not interfere with mastication and occlusion ; and 8) it can be universally fabricated in advance and commoditized . because the prefabricated device can be used immediately after adjusting of the length of the tube , clinicians may reduce cost , time , and effort required for this treatment . it is thought that the device can be commoditized in three types , including a universal standard type , a flat entrance type for posterior teeth , and a small diameter type for anterior teeth . this device will be quite useful , simple , hygienic , and effective for odontogenic cystic lesions during the long treatment period ( fig .
decompression is considered an effective treatment for odontogenic cystic lesions in the jaw . 
 a variety of decompression devices are successfully used for the treatment of keratocystic odontogenic tumors , radicular cysts , dentigerous cysts , and ameloblastoma . 
 the purpose of these devices is to keep an opening between the cystic lesion and the oral environment during treatment . 
 the aim of this report is to describe an effective decompression tube using a stainless steel tube and wire for treatment of jaw cystic lesions .
