The aim of this study was to assess the NPC enlargement resulting from fusion with a PRL and its relationship with the surrounding anatomical structures.<\/jats:p><\/jats:sec><jats:sec><jats:title>Material and methods<\/jats:title><jats:p>A total of 100 patients was retrospectively recruited and divided into two groups: case group and control group. The case group consisted of 50 cone\u2010beam computed tomography scans of the maxilla of patients (32 males, 18 females; age range: 11\u201083\u00a0years) with a known history of dentoalveolar trauma in the maxillary anterior region and the presence of an undiagnosed and\/or asymptomatic NPC and PRL fusion. An age\u2010 and gender\u2010matched control group of 50 patients (32 males, 18 females; age range: 11\u201082\u00a0years) without trauma history to the upper anterior teeth, demonstrating normal maxillary scans, was recruited. A subjective scoring criterion was established for assessing the characteristics of the fused lesion and its relationship with the buccal\/palatal alveolar cortex, nasal cavity cortex, NPC cortical border, and maxillary sinus floor.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The fused NPC and PRL was mainly lobular in appearance (88%) with non\u2010corticated well\u2010defined margins (80%). Male patients showed larger (68%) dimensions compared with female patients (32%). The NPC cortical bone was the most commonly perforated structure in relation to fusion (72%), whereas maxillary sinus cortical bone was the least effected (2%). A statistically significant difference was observed between the NPC dimensions in the control and test groups, with fused lesions having larger mesiolateral, craniocaudal, and buccopalatal dimensions (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a0.001).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Periapical radiolucencies should be treated as soon as possible before they fuse with NPC.
