phenylephrine-hydrochloride and Ameloblastoma

Ameloblastoma (AM) is a slow growing and aggressive benign tumor with an odontogenic epithelial origin arising from the mandible or maxilla. The odontogenic neoplasm invades local tissues asymptomatically and accounts for 1% of oral tumors and over 10% of odontogenic tumors. A 64-year-old man with a history of allergic fungal rhinosinusitis (AFRS) undergoing a revision image-guided endoscopic sinus surgery was found to have a fibrous mass suspicious of malignancy projecting inferolaterally and attached to the floor of the left maxillary sinus. Diagnostic biopsies were taken, and additional surgery was required to successfully resect the tumor via a transnasal endoscopic dissection. Multiple permanent pathology samples concluded the diagnosis of an AM. Endoscopic investigations led to the incidental discovery and ultimate complete endoscopic resection of the AM. The utilization of an endoscopic resection compared to the traditional maxillectomy with reconstruction results in significant less short and long-term morbidity for the patient.

Superiorly based nasolabial flap is an interesting solution for reconstruction of moderate size maxillary defects. The operative technique and its results are described. Advantages (reliability in flap vascularity, versatility, easiness of elevation) and limits of this procedure for closure maxillary defects are mentioned. Then they are compared to the other reconstructive maxillary techniques.

A clinical study was made of three cases of Ameloblastoma (Adamantinoma) of the maxilla. One case presented with oro-antral fistula following extraction of a molar tooth. Extensive bone destruction and involvement of ethmoidal air sinuses and nasal cavity was seen in one of the patients. At times histological diagnosis can be difficult; therefore, accurate diagnosis should be obtained by an experienced histopathologist. Partial maxillectomy with a wide margin of healthy bone should be the choice of treatment in the majority of cases. There tumours are sensitive to deep-X-ray to a varying degree. One should consider radiotherapy post-operatively if growth has been excised inadequately. Radiotherapy may be helpful when surgery is contraindicated.
