“…A wide range of studies has reported the different indications for immediate cystectomy and cystostomy, as well as their respective advantages and disadvantages [3,7,19,20]. Data on bone healing after surgery and the shrinkage behaviour of bone lesions after a cystostomy is, however, still limited [12,[21][22][23]]. Yet, these shrinkage rates are needed to predict complete bone healing and to determine reasonable follow-up intervals during treatments.…”

Objectives There is a long history of studies into cystic lesions of the jaws. However, there is little data on postoperative bone regeneration. The aim of the study was to calculate the size of the residual bone lesions after cystostomies and cystectomies to predict the postoperative bone healing. Material and methods This retrospective study focused on patients undergoing cystectomy (n = 114) or cystostomy (n = 86), who were treated for cystic lesions between 2010 and 2015. New formulas were developed to measure the decrease in lesion sizes using the craniocaudal and mesiodistal diameters from preoperative as well as postoperative radiographs (panoramic radiographs, CT scans, CBCT). With these predictive models (calculated by linear regression analyses), it is possible to calculate how the lesions would shrink using initial size of the cyst and time after surgery for both dimensions. Results After cystostomy, the mesiodistal size was initial size 6.0 + 0.7 × initial size − 9.4 × time. The craniocaudal size was 5.1 + 0.7 × initial size − 7.3 × time. After cystectomy, the mesiodistal size was 0.4 + 0.7 × initial size − 8.4 × time. The craniocaudal size was 0.4 + 0.5 × initial size − 6.4 × time (R 2 = 0.59 and 0.67, respectively). Conclusion These formulas are suggested to be used to calculate residual size of bone lesion after cystostomy and cystectomy to predict postoperative bone healing. Clinical relevance The formulas are based on deliberately simple measurement using only panoramic radiographs to encourage their application in daily clinical practice.

“…Previous studies on the 3-D volumetric analysis of the effect of decompression surgery for odontogenic cystic lesions including ameloblastoma have reported that the volume reduction was related to the duration of decompression and the original size of the lesion 7,8,10) . In particular, Jeong et al reported that decompression was more effective when performed for more than 6 months 8) .…”

“…Although marsupialization and decompression are different procedures, they share the principle aim of reducing the size of cystic lesions by lowering the pressure of cystic fluid and inducing bony apposition to the cystic walls 7,8) . Marsupialization and decompression were suggested by Partsch and are referred to as the Partsch I procedure 9) .…”

“…The Partsch II procedure comprises enucleation and primary closure 9) . Decompression involves making a small opening in the cyst and keeping it open by using a rigid drainage tube that facilitates the irrigation of the cavity and prevents food impaction or microorganism accumulation 8,9) . In contrast, marsupialization, which is considered the more definitive treatment, involves converting the cyst into a pouch by creating a large window in the bone, and then connecting the inner cystic wall to the oral mucosa, with exposure of the cyst lining to the oral environment 7,9) .…”

The aim of this study was to evaluate the effect of marsupialization therapy for unicystic ameloblastoma by using three-dimensional (3-D) volumetric analysis with OsiriX software. This retrospective study assessed patients with unicystic ameloblastoma treated using marsupialization. Four patients (age, 29.00 ± 21.65 years) were included in this study, all of whom had mandibular ameloblastoma. The period between computed tomography before and after marsupialization was 5.75 ± 1.71 (4-8) months. In 3-D volumetric analysis using OsiriX software, the mean volume of the lesions before marsupialization was 22.91 ± 28.74 (6.23-65.86) cm 3 , and that after marsupialization was 11.28 ± 15.60 (2.19-34.62) cm 3. The mean reduction in volume was 11.63 ± 13.16 (4.03-31.24) cm 3 , and the volumetric reduction ratio was 56.42 ± 7.60 (47.43-64.76)%. Additional conservative treatments were performed after marsupialization; however, radical resection with surgical margins was avoided because of the reduction in the volume of the ameloblastoma, owing to marsupialization, in all cases. In conclusion, marsupialization contributed to reducing the volume of unicystic ameloblastoma and avoiding radical resection, which reduces patients' quality of life. The results suggested that marsupialization should be favored over other methods in the treatment of unicystic ameloblastoma.

A volumetric prediction model for postoperative cyst shrinkage

Objectives With only limited information available on dimensional changes after jaw cyst surgery, postoperative cyst shrinkage remains largely unpredictable. We aimed to propose a model for volumetric shrinkage based on time elapsed since cyst surgery. Material and methods We used data from patients that underwent cyst enucleation or decompression between 2007 and 2017 and had at least three computed tomography (CT) scans per patient. We fitted one simple exponential decay model [V(t) = V0 · e−ɑt] and one model with a patient-specific decay rate [Vk(t) = V0 · e−βt + γkt]. Results Based on 108 CT scans from 36 patients (median age at surgery: 45.5 years, IQR: 32.3–55.3, 44% female), our simple exponential decay model is V(t) = V0· e−0.0035t where V(t) is the residual cyst volume after time t elapsed since surgery, V0 is the initial cyst volume, and e is the base of the natural logarithm. Considering a patient-specific decay rate, the model is Vk(t) = V0· e−0.0049t + γkt where γk is normally distributed, with expectation 0 and standard deviation 0.0041. Conclusions Using an exponential regression model, we were able to reliably estimate volumetric shrinkage after jaw cyst surgery. The patient-specific decay rate substantially improved the fit of the model, whereas adding specific covariates as interaction effects to model the decay rate did not provide any significant improvement. Clinical relevance Estimating postoperative cyst shrinkage is relevant for both treatment planning of jaw cyst surgery as well as evaluating the clinical success of the surgical approach.
