“…Lai et al postulated that there may be a higher incidence of maxillary sinus ectopic teeth in men than in women (14). In our study, 6/10 (60%) were men, this male predominance among our patients is consistent with Lai et al results.…”

“…A coexisting dentigerous cyst accompanying the ectopic tooth in the maxillary sinus was reported in several articles (3,11,14,17,(19)(20)(21). This cystic correlation is consistent with our experience, where a dentigerous cyst associated with the ectopic tooth was found in 7/11 (63.6%) of the ectopic teeth.…”

“…Due to its rarity, the literature on tooth impaction in the maxillary sinus is limited to case reports. Three previous studies reviewed the cases published in English literature and reported on only 35 cases e231 of ectopic teeth in the maxillary sinus from 1927-2011, and more recently on 65 cases from 1966-2012 (13)(14).…”

Background: Ectopic teeth in maxillary sinus is rare and are usually removed via sub-labial trans-canine fossa approach (SLCFA). The aim of our study was to present our experience with extraction of ectopic teeth in the maxillary sinus via transnasal endoscopic approach (TEA). Material and Methods: Rhinologists were asked to share their experience in the management of ectopic teeth in the maxillary sinus. Data were reviewed retrospectively. Results: Eleven cases were reported in 10 patients from 2010 to 2019, six males and four females with a mean age of 33.5 +/-17 years (range 16 to 61). Seven patients complained of sinonasal symptoms, two were diagnosed incidentally during routine dental work-up, and one had oro-antral fistula. In eight patients, a cyst coexisted within the maxillary sinus. Teeth were located arbitrarily within the sinus. All cases were operated by TEA. One patient had self-limited periorbital emphysema, one had transient cheek numbness, and one had early post-operative bleeding that stopped after endoscopic cauterization. Long-term follow-up revealed good clinical outcomes. Conclusions: Transnasal endoscopic removal of ectopic teeth from the maxillary sinus is a feasible and rational approach when SLCFA is contraindicated.

“…Cone beam CT scan was performed in the region, inasmuch as it allows a larger area detailing, thus optimizing surgical planning, once it is possible to visualize the tooth structure morphology, and root inclination and position in relation to the underlying structures. Thus, it is possible to predict eventual transoperative intercurrences, postoperative complications, and prognosis 181617. In this case, the CT scan allowed the observation of the exact location of both ectopic structures, which were inserted into the roof of the maxillary sinus and the medial wall, closely related to the orbital floor and nasal cavity, respectively.…”

This article presents a case report of an adult patient with chronic sinusitis related to the presence of two erupted ectopic teeth located atypically in the maxillary sinus roof/orbital floor after a long latency period associated with childhood facial trauma. This article aims to show the treatment of chronic sinusitis of odontogenic origin by surgical removal of ectopic teeth in an unusual position by direct visualization. This case report discusses the signs and symptoms of chronic sinusitis linked to the presence of ectopic elements and associated with an inflammatory cyst, the choice of complementary tests for diagnosis and surgical treatment through the Caldwell-Luc procedure. After a 2-year follow-up period, the patient presently shows clinical improvement, thus demonstrating the success of the chosen treatment.

“…Any interruption of the tooth development process, developmental anomalies, crowding of dentition, trauma, or iatrogenic predispositions can cause the impaction in the maxillary sinus. In some cases, the impaction has an idiopathic etiology [ 18 ].…”

Patient: Male, 48-year-old Final Diagnosis: Inverted impaction within the maxillary sinus Symptoms: Asymptomatic Clinical Procedure: — Specialty: Dentistry Objective: Unusual clinical course Background: The maxillary third molar is considered one of the most impacted teeth and can present in different types based on the direction and depth of the impaction. However, the inverted type of maxillary third molar impaction is a rare condition, with few reported cases in the current literature. Case Report: We report an extremely rare case of a 48-year-old man with an inverted maxillary third molar situated in the maxillary sinus in direct contact with the posterior wall of the sinus, with a portion of the coronal part perforating the infratemporal fossa. Because of the anatomical and structural complexity of the impaction and because the tooth has never been symptomatic, the case was conservatively managed after weighing the risks and benefits of surgical intervention. A 2-year follow-up was made to ensure no changes in the impaction location, confirming the validity of the conservative approach. Conclusions: This case is the first reported inverted maxillary third molar impacted in such an anatomical location. This reported case contributes to existing knowledge regarding this rare type of impaction and that this rare impaction location can present congenitally with a non-iatrogenic origin. A thorough dental history and clinical and radiographical examinations will aid dental professionals in their clinical decision making for patients with similar presentations.

Anomalous Morphology of an Ectopic Tooth in the Maxillary Sinus on Three-Dimensional Computed Tomography Images

Abstract: We describe a case of an incidentally-diagnosed ectopic tooth showing anomalous morphology in the maxillary antrum, using three-dimensional reconstruction of computed tomography images of the tooth obtained by multi-detector computed tomography.
