AbstractObjectives The so-called globulomaxillary cyst, described as a fissural cyst, caused by entrapped epithelium between the nasal and maxillary process, is no longer considered for its own entity. Nevertheless, cystic lesions, which correspond to the previous image of globulomaxillary cysts, do still occur in daily practice. This raises the question to which entities pathological processes in this particular region actually belong to.
Materials and methods In a retrospective study, 17 cases (12 men and 5 women, 1259 years old) of primarily diagnosed globulomaxillary cysts are analysed according to clinical, radiological and histological aspects, catamnestic processed and assigned to a new entity. The results are compared with the international literature and draws conclusions on the diagnostic and therapeutic procedure.
Results Seven lateral periodontal cysts, four radicular cysts, two keratocystic odontogenic tumours, one adenomatoid odontogenic tumour, one periapical granuloma, one residual cyst and one undefined jaw cyst were determined.
Conclusions According to the results of our study and the data from the international literature, the entity globulomaxillary cyst is no longer justified.

Introduction
The globulomaxillary cyst was first described in 1937 as being a truly fissural cyst forming at the junction of the globular process and the maxillary process [1]. This theory of origin was disputed at an early stage [24]. Consequently, it was also increasingly doubted whether the globulomaxillary cyst qualified for being considered an entity of its own [510]. Following Hring et al. (2006), the notion of globulomaxillary is no longer used for an entity of its own, but rather for the anatomical localisation of a lesion that appears between the maxillary lateral incisor and the adjacent canine and that may be definitely diagnosed only after a thorough clinical, radiological and histopathological examination [9]. Nevertheless, cystic lesions corresponding to the previous image of the globulomaxillary cyst are comparatively common in daily practice, as we can show in our study, too. The...
