Odontogenic Sinusitis

We report the case of a 38-year old male patient with sinusitis caused by an infected follicular cyst due to an ectopic impacted third molar in the right maxillary sinus. A 10-day antibiotherapy regimen was administered; subsequently, the cyst and the third molar were removed achieving complete recovery. Fibrous dysplasia was diagnosed at follow-up examination (occupation of the maxillary sinus by bone tissue was observed in a radiographic examination) and confirmed by biopsy. In cases of odontogenic sinusitis, thorough examination is crucial, as evidenced by the case reported in this study. A Literature review was performed in order to identify the diagnostic methods currently available and the clinical features, complications and treatment for both, odontogenic maxillary sinusitis and fibrous dysplasia.

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.

Purpose of the study: To describe the management of orosinusal pathology by combined transnasal endoscopy and oral combined. Methods: The 54-year-old patient underwent a dental and otolaryngological evaluation for left odontogenic maxillary sinusitis in relation to plausible dental follicular cyst of ectopic element 2.8. The symptoms reported at the time of access to the hospital were nasal obstruction and nocturnal rhonchopathy. To the ENT evaluation in videorinoscopy with rigid optics, complex deviation of the nasal septum was relevated with not any evident formations or pathological secretions. While on inspection of the oral cavity the mucous membranes appeared unscathed. Alveolus of 1.6 previosuly extracted was evident. The radiological examination, facial CT, revealed the left maxillary sinus almost completely occupied by a cystic appearance, with thin calcified walls and homogeneous content that has a dental element, probably the 2.8, which fenestrates the vestibular cortex of the lateral wall of the maxillary sinus. This lesion erodes the medial wall of the sinus, obliterating the ostio-meatal complex and imprinting the ipsilateral ethmoidal cells. Biohumoral tests showed normal coagulation parameters, indices of renal function, liver and ionemia. The patient under general anesthesia and oral intubation with a combined intervention of the left anterior FESS, intrasulcular flap from dental elements 2.7 to 2.3 with mesial releasing incision, moderate osteotomy, ectopic 2.8 extraction and enucleation of the cystic lesion with simultaneous closure of the orosinusal communication with advancement of the Bichat adipose bolla and closure by first intention. In the same session, the ENT moment is carried out trans nasally for total left uncinectomy, medium antrostomy with the union of the natural ostium and the accessory ostium. Bilateral lower turbinoplasty with bipolar forceps. The patient was then controlled after 15 days and six months, showing good healing and no signs of recurrence at the rhinoscopic check on the physical examination of the oral cavity. Results: based on the clinical and radiological aspect, the diagnosis of a follicular dentigerous cyst (WHO 2017) covered by a multi-layered non-keratinized paving epithelium, with moderate chronic inflammation, including gigantocellular and cholesteric crystals, is reached from the microbiological and histological examination. Necrotic amorphous material coexists including rare hyphae and fungal spores, with therefore mycotic and actinomycotic super infection. Conclusions: The combined oral and nasal intervention, allowed by the collaboration between the oral surgeon and ENT, has made it possible to shorten the healing time and to resolve the pathology without any sign of recurrence.

Ectopic development of teeth in nondental areas is uncommon, especially in the maxillary sinus. A panoramic radiograph is the routine diagnostic radiographic examination performed for this type of eruption, although cone beam computed tomography (CBCT) is highly recommended for further localization of the ectopic tooth and assessment of the characteristics of any associated lesion before a surgical procedure. We report a case of a 13-year-old female student who presented with purulent discharge posterior to the upper right second molar with a bad taste and foul odour. Radiographic examination revealed a maxillary third molar tooth located at the posterosuperior aspect of the right maxillary sinus with a hyperdense lesion surrounding the crown, obliterating the sinus cavity. Both the tooth and dentigerous cyst were surgically removed under general anaesthesia through Caldwell-Luc antrostomy. After a three-month follow-up, the patient was symptom free and had an uneventful recovery. The rare and critical location of the reported third molar along with the infected dentigerous cyst indicates its complete enucleation to avoid complications as recurrence or malignant transformation.

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.

Compound Odontoma

Introduction: The dentigerous cyst, also called a follicular cyst is an odontogenic cyst that develops in association with crown of an impacted tooth, predominantly in mandibular third molars of young patients. The Odontoma is a ectomesenquimal tumor of unknown origin that are more considered developmental malformations (harmatomas) than benign neoplasms. Occasionally, the dentigerous cyst is associated with odontoma. Objective: The article aims to report a case of surgical treatment of dentigerous cyst associated with compound odontoma and unerupted tooth in anterior region of the mandible. Case report: A male patient, 17 years of age, without systemic changes, was sent to the Center for Dental Specialties of Horizonte, Ceará, Brazil, specialty of Oral and Maxillofacial Surgery, for diagnosis and treatment of oral lesions visualized after periapical radiographic examination to determine failed eruption of element 42. Observing the periapical radiograph it was possible to visualize radiopaque lesion suggestive of a compound odontoma and a cystic capsule in association with the element 42. A panoramic radiographwas requested and it was planned a surgical removal of odontoma with curettage of bone cavity and removing the cystic capsule and element 42. There were no significant postoperative complications, the suture removal was performed 7 days after surgery where it was possible to observe a good healing, no swelling and no paresthesia. Conclusion: The treatment of choice is surgical excision of the lesions with the tooth associated to the cyst, it should be performed with proper planning, avoiding injury to vital structures and should not be delayed in order to avoid possible occlusion sequelae.

During the surgical removal of maxillary molars, tooth or fragment displacement into the maxillary sinus may occur. The presence of foreign bodies inside these cavities leads to complications such as mucoceles, cellulitis, oroantral fistulae and maxillary sinusitis, to prevent the arise and worsening of complications, these events must be addressed in an early stage. This article aims to report the removal of a tooth root from the maxillary sinus, through the modified Caldwell-Luc (CLM) approach and describe the current indications for the Caldwell Luc technique. It reports an upper third molar surgery in which a patient had the distal root of the left superior third molar displaced into the maxillary sinus, later showing signs of sinus opacification and loss of patency of the maxillary ostium obstructed by the root. After antibiotic treatment, the root was recovered through the CLM technique by local anesthesia, without complications. Foreign bodies in the maxillary sinuses must be urgently addressed, avoiding the development of infectious conditions, the CLM approach is the choice approach to manage these complications by a simple and safe way.

Objectives: To characterize the radiographic features of maxillary ameloblastoma (AM), odontogenic keratocyst (OKC) and dentigerous cyst (DC) comparatively by using spiral CT and cone beam CT (CBCT). Methods: Clinical records, histopathological reports, and nonenhanced spiral CT or CBCT images of 191 consecutive patients with primary maxillary AMs, OKCs, or DCs were retrospectively acquired, and radiographic features were analyzed. Results: The study included 118 males and 73 females (age: 5–84 years). 72.0% of AMs and 84.3% of OKCs originated from the posterior maxilla, while 69.6% of DCs occurred in the anterior maxilla. Among 25 AMs, 44.0% were of desmoplastic type, with honey-combed appearance. 84.0% of AMs were circular or oval in shape, 84.0% expanded buccally, and 36.0% invade the nasal floor. Among 89 OKCs of 88 patients, 61.8% were circular or oval, 58.4% expanded buccally, 49.4% were dentigerous, 41.6% nearly filled the maxillary sinus, and 13.5% invaded the nasal floor. 93.7% (74/79) of DCs enveloped a single tooth, and the tooth–cyst relationship was centripetal in 35, eccentric in 30, and circumferential in 9. Moreover, 98.2% (55/56) of the cysts enveloping a supernumerary tooth were DCs, while 80.9% (38/47) of the cysts enveloping the third molar were OKCs. Conclusions: Maxillary AMs tend to grow with buccal expansion and invade the nasal floor, and DAs with honey-combed lobularity are common. Maxillary OKCs have variant shapes and tend to invaginate the maxillary sinus. The tooth–cyst relationship of dentigerous OKCs and DCs can be centripetal, eccentric, or circumferential.
