A volumetric prediction model for postoperative cyst shrinkage.

ABSTRACT:

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 [V_k(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 mod
