“…The frontal sinus is the most frequently involved, followed by the ethmoidal and maxillary sinuses. Most cases are asymptomatic [25], explaining why they are generally found as incidental findings in imaging studies [26,27]. Symptoms are reported only in cases where the lesion presses and occupies spaces of adjacent structures [26].…”

The aim of this study was to report a rare case of an asymptomatic calcification of unusual size and shape, inside the maxillary sinus identified on a cone beam computed tomography exam and to discuss the importance of knowledge of the anatomy of maxillary sinus and its changes carefully evaluating the entire volume of the images, regardless of the region of interest. An 83-year-old female patient underwent a cone beam computed tomography exam for other diagnostic purposes in the maxillofacial region. When analyzing the entire volume, an image of unusual limits, hyperdense and calcified was found in the right maxillary sinus, close to the anterior and medial wall, with a rounded and homogeneous shape, occupying approximately one third of the maxillary sinus. There was no lytic or erosive lesions on the maxillary sinus wall. The main diagnostic hypotheses raised were giant anthrolith, mucous retention phenomenon and osteoma. Due to the anatomical complexity of the maxillary sinus, diagnosis in this region becomes a challenge. Considering the limitations of 2D exams, the cone beam computed tomography exam can be used to evaluate these structures. Knowledge of differential hypotheses is extremely important for the case to be conducted correctly, but it does not replace biopsy and histopathological examination.

Maxillary Sinus Osteoma as a Support for Dental Implant Associated to Sinus Augmentation Procedure: A Case Report and Literature Review

et al. 2022

Background: Maxillary sinus augmentation is a method extensively used to restore sufficient bone volume in the posterior maxilla to allow for the placement of fixtures. The purpose of the present case report was to describe a rare case of sinus osteoma used for implant support and to review the relevant literature. Materials and Methods: A 58-year-old man with a radiopaque intrasinusal lesion was referred for rehabilitation of the maxilla. The lesion was probably an osteoma and involved the nasal wall of the maxillary sinus. After discussing the options with the patient, he agreed to maintain the lesion and a sinus augmentation with a bone graft. A part of the osteoma was partially removed for histological analysis while avoiding perforation or tearing of the schneiderian membrane. After six months, 6 implants (Bone System Implant, Milano, Italy) were placed in the maxilla, two of which were inserted in the osteoma. Results: The two implants placed in the osteoma were perfectly osseointegrated. The graft material appeared well-integrated with no local signs of inflammation. No postoperative events or symptoms were reported after the surgery stages and at a 6-month follow-up. Regarding the two implants placed in the osteoma: article selection identified 9 case reports, 2 case series, and 1 retrospective study for a total of 58 subjects, 35 males and 25 females. The patients’ ages were heterogeneous and ranged between 12 and 79 years old. Conclusions: In the present case, we decided to leave the osteoma because it was asymptomatic and used as dental implant support. The effectiveness of the present investigation can provide useful guidance for surgeons and dentists in the management of similar clinical situations.
