Abstract
Ameloblastoma is a benign epithelial tumor that has aggressive, destructive and unlimited growth potential, having the capacity for recurrence and malignant transformation. Regarding the symptoms and clinical signs, the presentation of ameloblastoma is poor. In children and young people, ameloblastoma can be difficult to diagnose, because it mimics other benign lesions. Its diagnosis requires a combination of imaging data, histopathological analysis and molecular tests. The methods of treatment consist of radical surgery (segmental resection) and conservative treatments (enucleation with bone curettage). The particularity of the presented case is represented by the late request for medical consultation, a direct consequence of the measures implemented to prevent and control the spread of COVID-19.

Abstract
Ameloblastoma is a locally aggressive tumor derived from odontogenic epithelium. Although benign, its clinical behavior can often exhibit malignant characteristics. It is marked by slow and persistent growth with infiltration of adjacent tissues. Almost 70% occur in the mandible in patients older than 30 years. Recurrence of ameloblastoma from inadequate treatment is frequent. Because of its slow growth, recurrences can present decades after primary surgery. A primary ameloblastoma in an area outside the mandibular, maxillary, and infratemporal fossa regions has not been described in detail to date, with only 1 possible case mentioned in the literature. The authors present a case of primary temporal bone ameloblastoma in a 17-year-old boy. The tumor originated in the left mastoid, infiltrated the lateral semicircular canal, facial nerve, and cochlea, and adhered to the sigmoid sinus and posterior cranial fossa dura. Although invasion of multiple structures in the infratemporal fossa and temporal bone leads to variable disease presentation, this case is unique because the first symptom of disease was sudden and recurring unilateral sensorineural hearing loss. Surgery required transection of the facial nerve. Histopathology confirmed primary temporal bone ameloblastoma. The difficulties in achieving wide surgical margins, diagnostics, and further management are addressed.

Abstract
OBJECTIVE To investigate the application of submandibular gland flap with facial artery and vein pedicle, for repairing defects following tumor resection in the infratemporal region. PATIENTS AND METHODS Fifteen patients, including eight males and seven females ranging in age from 21 to 73 years, underwent surgical resection of tumors in the infratemporal region. Tumors were exposed using the submandibular incision approach and completely resected after pulling and rotating the mandible laterally. Mandibular osteotomy was performed for larger tumors or those that were not completely exposed. After tumor resection, the submandibular gland flap was used to fill up the residual defect following tumor resection. RESULTS The incisions healed well without exudation or infection (primary healing) postoperatively in all the patients. Long-term follow-up showed no tumor recurrence in all cases. Seven of the patients who underwent mandibular ramus osteotomy had numbness of the lower lip due to inferior alveolar nerve injury. No other complications were observed postoperatively. CONCLUSION The submandibular gland flap with facial artery and vein pedicle is a reliable, effective, and easy approach for repairing the defects caused by tumor resection in the infratemporal region, and has great potential for application in the clinical setting.

Abstract
The human otic ganglion (OG) is not readily accessible during ordinary anatomical teaching courses because of insufficient time and severe difficulties encountered in dissection. Accordingly, most anatomical descriptions of its location, relation to neighbouring structures, size and shape are supported only by drawings, but not by photographs. The aim of this study has been to present the OG with associated roots and branches in dissected anatomic specimens. Following cumbersome dissection and precise photo-documentation, a detailed analysis of location, syntopy and morphology was performed. We carried out this study in 21 infratemporal fossae of 18 cadavers and were able to identify the OG, the mandibular-, the inferior alveolar- and the lingual nerve in all of them. We found no significant variation regarding the location of the GO in the infratemporal fossa and its syntopy to the adjacent structures. An OG resembling the classic description was found only in 90.50% of the cases. All 3 roots (parasympathetic, sympathetic and sensory) could be identified only in 82.3% of the specimens. The established presence of ganglionic branches varied from 0% (communicating rami to the meningeal branch of the mandibular nerve, to the greater petrosal nerve and to the lingual nerve) to 90% (r. communicans to n. canalis pterygoideus). We conclude that precise knowledge of this enormous variety might be very helpful not only to students of medicine and dentistry during anatomical dissection courses, but also to head and neck surgeons, ear-nose-throat specialists and neurosurgeons when treating pathology of pre- and postganglionic fibres.

Abstract
Ameloblastoma is a unique, histologically benign but aggressive neoplasm of the jaws, arising from odontogenic epithelium with potency to cause extensive destruction of jaw bones and infiltration into the surrounding tissues. Recurrences are common after incomplete treatment. Recurrences can occur at difficult sites such as temporal and infratemporal fossa, orbit, anterior cranial base, paranasal sinuses etc. Fine needle aspiration cytology or core biopsy of these recurrent lesions may be misleading. Clinical course and radiological features help immensely in these situations. Good communication between surgeon, radiologist, and pathologist is of paramount importance.

Abstract
Ameloblastoma is a rare odontogenic tumor with characteristics of epithelial tissue that produces enamel for the developing tooth. This lesion is generally considered benign, but has malignant forms that invade locally and metastasize. We present a 60-year-old man with maxillary ameloblastoma that after multiple recurrences developed intracranial extension with dural involvement of the middle cranial fossa and was treated by endoscopic transnasal resection followed by radiation therapy. Our technique and intraoperative findings are described with a review of the literature on intracranial ameloblastoma. This patient represents a unique account of endoscopic transnasal resection being utilized in the treatment of intracranial extension of ameloblastoma and demonstrates potential for application in similar cases.

Abstract
Ameloblastic carcinoma is a very rare malignant odontogenic tumour with characteristic histopathological and clinical features, which requires aggressive surgical treatment and surveillance and, therefore, differs from ameloblastoma. Metastasis typically occurs in the lung. Only one patient with metastasis to the skull has previously been described and no prior case reports have presented MRI and positron emission tomography-CT (PET-CT) imaging findings. We describe a case of ameloblastic carcinoma with metastasis to the skull and lung with emphasis on imaging features including MRI and PET-CT.

Abstract
Ameloblastomas are benign odontogenic tumors but are locally aggressive, most commonly occurring in the mandible and in the third to fifth decade of life. The male-to-female ratio is approximately equal. Recurrence of ameloblastoma due to inadequate treatment is often described. Recurrences in the temporal area are very rare and are related to the type of primary treatment. The authors describe a case of ameloblastoma recurrence in the temporal area and review the literature regarding recurrence and treatment.
