Ectopic Third Molar

This case series describes an alternative approach for removing ectopically erupted tooth in the maxillary sinus using an improved endoscopic approach known as modified endoscopic-assisted sinus surgery (MESS). We reviewed medical charts and radiographs of patients who underwent surgical removal of an ectopic tooth in the maxillary sinus using MESS. The surgical technique consisted of creating a bony window in the maxillary sinus wall with a pre-adapted microplate, which was repositioned after the tooth was removed. For all the patients included in this study, there were no postoperative complications clinically and radiographically. At the time of microplate removal, satisfactory bone regeneration was observed around the bony window margins of the maxillary sinus wall. MESS is an effective technique that modifies and integrates the techniques of the conventional Caldwell-Luc procedure (CLP) and functional endoscopic sinus surgery (FESS) and can be used to remove ectopic tooth in the maxillary sinus by avoiding the risk of postoperative sinus-related complications.

Ectopic Third Molar

The maxillary sinus is a pneumatic space that, when inside it contains foreign bodies, can trigger infections or inflammations of different severities, causing the appearance of cysts, tumors or the development of chronic sinusitis. Imaging is essential for the correct diagnosis of the case, as well as surgical planning for the removal of the foreign body. The present work aims to describe a clinical-surgical case of a patient with an ectopic third molar in the maxillary sinus, emphasizing the clinical, radiographic characteristics, therapeutic conduct and surgical technique, as well as showing the importance of theoretical and practical knowledge regarding the subject. A 49-year-old female patient attended the university’s dental clinic for surgical removal using the Caldwell-Luc technique of the ectopic upper third molar in the left maxillary sinus. The surgical removal of the ectopic element in the maxillary sinus was effective in the case presented, preventing the patient from future pathologies that could affect the sinus, as well as the symptomatological reduction of sinusitis.

Ectopic Third Molar

A dentigerous cyst or follicular cyst is a form of odontogenic cyst. It is believed that it forms during the development of the tooth and is associated with pressure exerted by the crown of an unerupted (or partially erupted) tooth on the fluid within the follicular space. Typically, dentigerous cysts are painless and discovered during routine radiographic examination. However, they may be large and result in a palpable mass. Additionally, as they grow they displace adjacent teeth. They almost exclusively occur in permanent dentition. The cyst is lined by stratified squamous non-keratinizing epithelium. About 70% of dentigerous cysts occur in the mandible and 30% in the maxilla. Dentigerous cysts associated with ectopic teeth within the maxillary sinus are very rare. We report radiologic and pathologic features in a rare case of infected dentigerous cyst of maxillary sinus arising from an ectopic third molar in a 21-year-old female patient.

Ameloblastoma (AM) in the maxillary sinus is rare. This benign entity shows locally invasive, destructive and aggressive behaviour and a high rate of recurrence. Therefore, the course of treatment is radical resection. We report the case of a 38-year-old man presenting with signs of recurrent sinusitis in the Ear, Nose and Throat Department. Transnasal flexible endoscopy revealed a cystic mass in the right inferior and middle nasal passage. CT scan showed an obliterated right maxillary sinus with a ballooning effect and pressure atrophy of the lateral sinus wall, without possible differentiation of the middle and low nasal turbinate. The patient was treated with transnasal functional sinus surgery; pathology stated AM. AM in the maxillary sinus is rare, locally destructive and therefore as a gold standard is resected radically to prevent recurrence. We demonstrate a conservative approach; explicitly, we combined a transvestibular and functional endoscopic sinus surgery resection of the AM to maintain function and reduce the possibility of postoperative impairments. Whether the strategy of treatment for AM is conservative, it nonetheless can result in a recurrence-free status. Nevertheless, inclusion into an oncological follow-up-programme with regularly performed MRI and CT is recommended.

ABSTRACT Ectopic eruption of teeth into a region other than the oral cavity is rare although there have been reports of teeth in the nasal septum, mandibular condyle, coronoid process, palate, chin and maxillary sinus. Eruption of ectopic teeth in maxillary sinus usually is found incidentally on routine radiological investigations. We present a case of an ectopic maxillary third molar tooth with dentigerous cyst that caused chronic purulent sinusitis in left maxillary sinus.

Importance: Safe entry into sphenoid sinus is critical in endoscopic sinus and skull base surgery. A number of surgical landmarks have been used to identify the sphenoid sinus ostium during endoscopic endonasal surgery with variable reliability and intraoperative feasibility. Objective: To determine if the posterior wall of the maxillary sinus is a reliable landmark to determine the depth of the sphenoid sinus ostium during anterior to posterior dissection. Design, Setting, and Participants: Prospective study of adult patients undergoing endoscopic sinus surgery between August 2016 and September 2017. Measurements were made intraoperatively between the depth of the posterior maxillary sinus wall and sphenoid sinus ostium. Main Outcomes and Measures: The primary measurement is the distance between the depth of the posterior maxillary sinus wall and sphenoid sinus ostium. Additional data points included age, gender, surgical indication, and primary versus revision endoscopic sinus surgery. Results: Forty-five patients (38% male, 62% female) with an average age of 56 were enrolled, resulting in 88 operated sides. The average distance between the depth of the posterior wall of the maxillary sinus and the sphenoid ostium was 1.5 mm ± 1.4 mm. The most common position of the sphenoid sinus ostium was posterior to the level of the posterior maxillary sinus wall (54%), followed by same level (23%) and anterior (23%). There was no significant difference between different disease states ( P = .75) and between primary and revision cases ( P = .13). Conclusions and Relevance: The posterior wall of the maxillary sinus serves as an adjunctive intraoperative landmark to determine the depth of the sphenoid sinus ostium. While the posterior wall of the maxillary sinus approximates the depth of the sphenoid sinus ostium, the relative position is variable and can be anterior or posterior.
