Primary intraosseous odontogenic squamous cell carcinoma (PIOSCC) is a rare tumor. The incidence is low, and approximately 200 cases are reported in literature. The etiology is associated with the malignant degeneration of embryological remains. Differential diagnosis includes alveolar carcinomas, jaw metastases from other locations, odontogenic tumors, and tumors of the maxillary sinus. However, the diagnosis could be delayed due to the absence of symptoms in early stages. Surgery represents the first choice treatment...

Painful trigeminal neuropathy attributed to a space-occupying lesion (code 13.1.2.5 in the International Classification of Headache Disorders, 3rd edition [beta version]) is an orofacial pain condition that has characteristics of classical trigeminal neuralgia but is caused by a space-occupying lesion. We present 4 cases of intracranial lesions mimicking odontogenic pain as follows: case 1, a 61-year-old woman presented with a chief complaint of aching soreness in the right mandibular molar area for 1 year; case 2, a 59-year-old man presented with severe pain in the left maxillary and mandibular molars; case 3, a 72-year-old man presented with a chief complaint of facial shock-like pain on the left side; and case 4, a 75-year-old man presented with a chief complaint of paroxysmal pain and numbness in the buccal gingiva of the right mandibular molar region...

Dentigerous or follicular cysts of odontogenic origin are innocuous benign cysts that are often linked with the crowns of permanent teeth. A dentigerous cyst circumventing permanent teeth fails to erupt and is often displaced into ectopic positions in the upper and lower jaw in the maxillofacial region. In the maxilla or upper jaw region, the impacted teeth are often displaced and/or shift into the maxillary sinus and apart from the nasal septum, mandibular condyle, coronoid process and the palate, to harbour such ectopic eruptions of teeth...

BACKGROUND: Ameloblastoma is a benign epithelial odontogenic tumor. It is often aggressive and destructive, with the capacity to attain great size, erode bone and invade adjacent structures. Unicystic ameloblastoma is a rare odontogenic lesion, with clinical, radiographic and gross features of jaw cysts. The lesion histologically shows typical ameloblastomatous epithelium lining part of the cyst cavity with or without and/or mural tumor growth. Unicystic ameloblastoma usually presents in posterior mandibular ramus region, while it is rare and atypical in posterior maxillary region...

INTRODUCTION: The ectopic ciliated cyst is a rare non-odontogenic cyst which occurs as a delayed complication after maxillary sinus radical surgery; this lesion emerges due to the destruction of the sinus mucosa during the surgery and entrapment of the respiratory epithelium in the region. This lesion has been observed in very rare cases following genioplasty and bimaxillary orthognathic surgery. CASE REPORT: We reported a case of the ectopic ciliated cyst in in the mandible of a 37-year-old Iranian woman following genioplasty and Lefort 1 surgery after 2 years...

INTRODUCTION: The maxillary sinus can be affected by dental infections because of its close relationship with upper teeth. This study aimed to assess the most common types of maxillary sinus alterations and to associate them with odontogenic conditions using cone-beam computed tomographic (CBCT) images. METHODS: CBCT scans of 400 patients showing sinus disease in 1 or both maxillary sinuses were evaluated. Sinus alteration was considered as follows: generalized or localized mucosal thickening (MT), maxillary sinusitis (MS), and retention cysts (RCs)...

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...

Dentigerous cyst (DC), also known as follicular cyst, is an odontogenic cyst with fluid accumulation between the crown and enamel organ of an unerupted tooth, pushing the crown away from the alveolar bone. The patients with DC in the maxillary sinus should be evaluated thoroughly by extraoral and intraoral examinations, proper diagnostic imaging procedures, and pathologic examination to avoid misdiagnosis of maxillary sinusitis. The standard treatment for DC in the maxillary sinus is often removed by Caldwell-Luc approach...

Haemophilic pseudotumour is a rare disease that occurs most often in femur, tibia, ilium or pelvic bone of a patient with haemophilia. Thus far, there have been only 31 reported cases in jaw bones and paranasal sinuses. Among them, the mandible is a more common site than the maxilla or paranasal sinuses. Here, we report a case of haemophilic pseudotumour in two parts of the maxilla. Contrast-enhanced CT showed an expansive and thinly corticated lesion with fluid attenuation at the left anterior maxilla which seemed like a post-operative maxillary cyst, ameloblastoma or odontogenic cyst...

Primary intraosseous squamous cell carcinoma (PIOSCC) is a rare type of odontogenic carcinoma that arises within the jaws. PIOSCC has no initial connection with oral mucosa and possibly develops from the residues of the odontogenic epithelium or from an odontogenic cyst or tumor. The diagnosis of PIOSCC can be difficult as it must be differentiated from other odontogenic carcinomas, such as malignant ameloblastoma, from SCCs arising from the overlying oral mucosa, from the primary tumors of the maxillary sinus or nasal mucosa, and from the tumors that have metastasized to the jaws from other primary sites...

OBJECTIVES/HYPOTHESIS: To evaluate the increase in access to the maxillary sinus (MS) with transnasal endoscopic medial maxillary sinus wall transposition (TEMMT), while preserving major structures of the nasal cavity. STUDY DESIGN: The study was divided into three parts: anatomical, radiographic, and case series. METHODS: Three cadaveric dissections (total of six sides) confirmed the feasibility of the TEMMT approach. Radiographic measurements using maxillofacial computed tomography scans were taken to assess the maximal antrostomy...

Keratocystic odontogenic tumor (KCOT) is one of the benign developmental odontogenic cystic lesions arising from impacted teeth. In comparison to other odontogenic cysts, such as radicular cysts and dentigerous cysts, KCOT is known to be more aggressive and is associated with a relatively high recurrence rate. Traditionally, KCOT has been treated with total resection through sublabial incision. Marsupialization is advocated to reduce surgical invasion. However in all the cases, marsupialization was performed in the oral cavity...

BACKGROUND: Cutaneous odontogenic fistulas or sinus tracts are frequently misdiagnosed and incorrectly treated, leading to unnecessary procedures and patient suffering. An understanding of the draining of cutaneous sinus tracts will lead to more appropriate treatment. Most cases respond to conservative, nonsurgical root canal therapy. Our objective is to report 2 cases of cutaneous sinus tract secondary to chronic periapical dental infection that were recently observed at our hospital...

INTRODUCTION: Odontogenic cutaneous sinus tract is a relatively rare occurrence that can be complicated to diagnose. The presence of a cutaneous lesion is often not even partly associated with a dental etiology because of the less frequency of occurrence in the case of dental symptoms. Consequently, the underlying dental cause is often missed leading to inappropriate diagnosis and treatment. CASE PRESENTATION: Here, we report the case of a 45-year-old man who presented with a persistent lesion of the cervical region...

IMPORTANCE: Pediatric jaw cysts represent a rarely symptomatic clinical entity and are not well addressed in the otolaryngology literature. It is important that otolaryngologists should be familiar with these lesions, which can manifest as jaw swelling or as paranasal sinus abnormalities. OBJECTIVE: To review the clinical presentation, radiologic features, management, and outcomes of jaw cysts in children treated at a single academic institution. DESIGN, SETTING, AND PARTICIPANTS: Retrospective medical record review at a tertiary care children's hospital among patients 16 years and younger who were seen with a cystic jaw lesion...

INTRODUCTION: Odontogenic cutaneous sinus tracts are often misdiagnosed as lesions of non-odontogenic origin, leading to the treatment of patients with unnecessary and ineffective therapies. Sinus tracts of endodontic origin usually respond well to endodontic therapy. However, root canal treatment of mandibular molars with aberrant canal anatomy can be diagnostically and technically challenging. Herein we present a patient with a cutaneous odontogenic sinus tract in the right submandibular area...

CONTEXT: The calcifying odontogenic cyst (COC), also referred to as calcifying ghost cell odontogenic cyst (CGCOC) is a heterogeneous lesion existing either as cystic or solid variant. Due to the fact that all CGCOC lesions are not cystic, and the biological behavior is often not consistent with a cyst, there has always been a controversy as to whether COC is a cyst or a tumor. The dentinogenic ghost-cell tumor (DGCT), a solid variant of the COC, is an uncommon odontogenic neoplasm occurring predominantly in later life...

In the oral cavity, lymphoproliferative disorders can manifest in various ways, often as an extranodal externalization. In the case presented here, it was a B cell lymphoma originating in the periapical bone of the anterior maxilla. X-ray revealed a periapical radiolucency associated with an intact tooth with no decay, fillings or history of trauma. The tooth tested non-vital. After root canal treatment, an apicoectomy was performed with a biopsy. The most common diagnosis would be of dental etiology. The pathology report revealed a non-Hodgkin's B cell lymphoma...

Extra oral sinus of odontogenic origin occurs when the purulent by-products of dental pulp necrosis spread along the path of least resistance from the root apex to the skin on the face. Patients presenting with cutaneous sinus usually visit a general physician or dermatologist first, as the lesion can mimic various dermatologic pathologies, ranging from an infected sebaceous cysts to a basal cell carcinoma. Despite systemic antibiotics, symptoms often persist causing further confusion, and at times leading to unnecessary surgical interventions...
