Foreign bodies in maxillary sinus (FBMS), whatever their origin or nature, are an unusual clinical condition. Diagnosis is based on the radiological findings in a clinical context of unilateral chronic rhinosinusitis. Treatment is the surgical removal of the intrasinusal foreign body.
To identify FBMS, the records of 68 patients with unilateral chronic rhinosinusitis operated on from 2000 to 2007 were reviewed.
From 68 records reviewed, we found 11 (16 %) FBMS. Ten (91 %) of these 11 foreign bodies were thought to come from the teeth and the last 1 (9 %) had a non odontogenic origin. Eight of the 11 (73 %) patients with FBMS presented with chronic maxillary sinusitis symptoms and all patients showed radiological findings. Treatment was the surgical removal of the foreign body, in 9 (82 %) patients through endonasal approach by functional endoscopic sinus surgery (FEES) and in the other 2 (18 %) patients a mixed surgical procedure by endonasal meatotomy and oral antrotomy was required.
Chronic maxillary sinusitis showing FBMS is rare and it must be suspected with a prior history of dental procedures. The most frequent source of FBMS is material of odontogenic origin, and non-odontogenic origin secondary to an external injury in an accident or assault is much more unusual. We also review the nature of these foreign bodies, their clinical implications and treatment options.

    ABSTRACT: Metallic foreign bodies are rarely found in the maxillary sinus, and usually they have a dental origin. Two main surgical app­roaches are currently used for the removal of foreign bodies in the maxillary sinus: the bone flap and the endoscopic sinus tech­niques. However, the treatment is not only surgical removal. We are reporting one case of foreign body like a hand sewing needle entered into the maxillary sinus through an unusual route— carious deciduous molar tooth. It was diagnosed by three-dimensional images from cone-beam computed tomography (CBCT) and removed by a simple procedure, with magnetic iron, thereby avoiding the risk of damage to a large portion of the alveolar bone near the maxillary sinus.

    ABSTRACT: Accidental displacement of endosseous implants into the maxillary sinus is an unusual but potential complication in implantology procedures due to the special features of the posterior aspect of the maxillary bone; there is also a possibility of migration throughout the upper paranasal sinuses and adjacent structures. The aim of this paper is to review the published literature about accidental displacement and migration of dental implants into the maxillary sinus and other adjacent structures. A review has been done based on a search in the main on-line medical databases looking for papers about migration of dental implants published in major oral surgery, periodontal, dental implant and ear-nose-throat journals, using the keywords "implant," "migration," "complication," "foreign body" and "sinus." 24 articles showing displacement or migration to maxillary, ethmoid and sphenoid sinuses, orbit and cranial fossae, with different degrees of associated symptoms, were identified. Techniques found to solve these clinical issues include Cadwell-Luc approach, transoral endoscopy approach via canine fossae and transnasal functional endoscopy surgery. Before removing the foreign body, a correct diagnosis should be done in order to evaluate the functional status of the ostiomeatal complex and the degree of affectation of paranasal sinuses and other involved structures, determining the size and the exact location of the foreign body. After a complete diagnosis, an indicated procedure for every case would be decided.

    ABSTRACT: Chronic maxillary rhinosinusitis of dental origin represents approximately 5 % of chronic maxillary rhinosinusitis. The diagnosis of this pathology is often delayed and mainly based on endoscopy and medical imaging. Its treatment is complex and requires the involvement of several teams. This article discusses two cases of chronic maxillary rhinosinusitis secondary to dental treatment. A literature review on the epidemiology, diagnosis, treatment and complications are also introduced.
