Challenges in the diagnostics and treatment of ectopic ameloblastic carcinoma: a case report.

Ameloblastic carcinoma (AC) is a rare and aggressive malignant epithelial odontogenic tumor, most commonly located in the mandible or maxilla. An extremely rare extragnathic localization of AC with no connection to the jaws, ectopic ameloblastic carcinoma (EAC), has so far been described only three times. This report presents a 64-year-old male with skull base ameloblastic carcinoma and offers a review of diagnostic and treatment challenges related to EAC.

Evaluation of sensitivity of teeth after mandibular fractures.

The sensitivity of teeth anterior to a fracture between the mental and mandibular foramina has been tested and followed up until reinnervation or 3 years has passed. This study assessed the reinnervation period, the number of denervated teeth, and their clinical importance. Fifty patients and 459 teeth were examined.

[Surgical treatment of lower jaw pseudoarthrosis as a result of fracture non-treatment following tooth extraction].

The pectoralis major flap in head and neck reconstruction: first 500 patients.

Aim: The aim of this study was to evaluate almost 20 years of using the pectoralis major flap in head and neck reconstruction at the Department of Maxillofacial Surgery, Zagreb.

Patients: In the period from 1981 to 1999, a total of 506 pectoralis major flaps were used for head and neck reconstruction in 500 patients. In all cases the flap was used after surgical resection of an advanced malignant tumour of the head and neck.

Calcified leiomyoma of the lateral pterygoid muscle in an 8-year-old boy.

Deep soft tissue leiomyomas are extremely rare benign tumors in childhood. An unusual case of benign calcified leiomyoma of the pterygoid muscle in an 8-year old boy is presented. Clinical manifestations and radiographic and histologicpathologic findings, as well as the differential diagnosis and possible histogenesis of this rare tumor, are discussed.
