Endoscopically Assisted Modified Caldwell-Luc Approach to Enucleation of Dentigerous Cyst With Ectopic Tooth From the Maxillary Sinus

Abstract

Dentigerous cysts in the craniomaxillofacial complex are a benign pathology commonly associated with ectopically placed teeth. Owing to slow and asymptomatic growth, they often attain considerable size before diagnosis that may compromise adjacent anatomical structures. Various techniques for removal of dentigerous cysts from the maxillary sinus have been described. This case report demonstrates a hybrid endoscopically assisted modification of the Caldwell-Luc approach to provide the technical advantages of both techniques.

Process of ectopic tooth formation in the maxillary sinus: follow-up observation of one case

“…9 Unfortunately, all previous studies in the literature are cross-sectional observations or case reports, and no studies have focused on the process of ectopic tooth formation. [2][3][4][5]9,10,16 Fortunately, in the present study, the dynamic process of the formation of an ETm in a young person was observed for the first time through follow-up examinations (Figure 2). An obvious ectopic tooth appeared at the age of 19 years in the posterior wall of the maxillary sinus; this tooth had been observed as only an area of soft tissue density and a small bone wall defect at the age of 16 years.…”

“…The literature indicates that ectopic teeth are found mostly in adults. 9,10,16 However, ectopic teeth might also form after permanent teeth have developed. 9 Unfortunately, all previous studies in the literature are cross-sectional observations or case reports, and no studies have focused on the process of ectopic tooth formation.…”

“…Endoscopic methods have been widely used in the management of ectopic teeth in the nasal cavity or sinuses. 2,8,10 Currently, nasal cavity ventilation expansion surgery and ETn extraction can be performed at the same time (Figure 3). However, the etiology of ectopic teeth remains unclear.…”

“…7 In most cases, ectopic teeth cause secondary conditions such as odontogenic cysts or nasal and maxillofacial symptoms. [8][9][10] However, with technological advances in imaging examinations, asymptomatic patients with ectopic teeth have also been reported. 7,11 Ectopic teeth affect a wide range of patients from children to advanced-age individuals.…”

Ectopic Tooth in the Roof of the Left Maxillary Sinus

“…The treatment of ectopic teeth usually comprises removal of the previous, taking into account its location and possible risks [ 4 ]. The traditional surgical approaches to maxillary sinus pathology are transoral Caldwell-Luc approaches or transnasal endoscopic surgery [ 5 , 12 ]. In recent literature, there is shift towards transnasal, endoscopic management of this pathology through a middle meatal antrostomy.…”
