Squamous cell carcinoma of the maxillary sinus and the oral part of the upper jaw. Comparison of treatment results.

The treatment results were compared in 77 patients with maxillary sinus squamous cell carcinoma (MC) and 53 patients with squamous cell carcinoma arising from the oral part of the upper jaw (OC). Both sets of patients received radiotherapy alone, or radiotherapy combined with surgery and/or chemotherapy. Computerized tomography was useful for the definition of the treatment volume. Intraarterial chemotherapy was given in 89 of 130 patients and in these patients the total radiation dose was reduced by about 10 Gy. No difference was found in the 5-year survival rate between the MC (65%) and the OC (66%) groups. The cumulative incidence of local failure was higher in MC (36%) than in OC (26%), whereas the ultimate incidence of neck node metastasis was higher in OC (43%) than in MC patients (18%). Half of the inoperable patients (9/18) were older than 80 years and had contraindications to anaesthesia and major surgery. The local recurrence rate was high in the inoperable MC patients (6/8). Contralateral sinus cancers occurred in 4 patients in the MC group.

Oronasal squamous cell carcinoma in an African hedgehog (Erinaceidae albiventris).

Oronasal squamous cell carcinoma was diagnosed in an adult African hedgehog (Erinaceidae albiventris). Clinically, the carcinoma presented as a firm right maxillary swelling with deviation of the nose to the left. The carcinoma was attached to the hard palate and protruded into the oral cavity. At necropsy, the carcinoma appeared centered in the right maxillary sinus, and had replaced the maxilla and extended into the nasal cavity. Metastatic foci were not found.

[Neurosurgical problems in craniofacial surgery for maxillofacial and ENT diseases].

From June 1978 to June 1990, 48 patients (34 patients with skull base tumors and 14 with congenital hyperterolism) were treated by combined craniofacial surgery. Cranial approaches were performed through the anterior fossa in 7 patients, middle fossa in 19, posterior fossa in 1, both anterior and middle fossa in 6, middle and posterior fossae in 1 and bilateral anterior fossae in 14. Neurosurgical problems were discussed.

Recurrent desmoplastic ameloblastoma of the maxilla: a case report.

A case of desmoplastic ameloblastoma recurring within 2 months of curettage is presented. This tumour appeared in the premolar region of the left maxilla with involvement of the antrum. The 24-year-old female patient was initially treated by curettage with wide surgical margins. Later, partial maxillectomy was carried out followed immediately by iliac bone graft. The case was followed with periodic plain radiography and computed tomography. The presence of a pulpally infected premolar and the atypical radiographic appearance obscured the disease. The biologic profile of this tumour is not fully understood because of the limited number of reported cases, coupled with inadequate long-term follow-up. A review of the lesion with emphasis on the pathogenesis of recurrence is discussed.

Complex odontoma of unusual size involving the maxillary sinus: report of a case and review of CT and histopathologic features.

An unusually large complex odontoma of the maxilla, occupying the entire maxillary sinus with expansion into the floor of the orbit and left nasal fossa, is reported. Although occurrences of complex odontomas are not considered rare, odontomas attaining extremely large sizes, especially involving the entire maxillary sinus with extension to the orbital floor and nasal fossae, are indeed, rare. In this article, the literature is reviewed to identify the common clinical, radiographic, and histologic characteristics of such lesions, and the outcome of treatment is discussed. Complex odontomas occasionally have significant growth potential, especially in the first two decades of life. Early recognition and consideration for surgical excision are key to successful management of this common odontogenic lesion. When odontomas extend beyond the alveolar process into the fascial planes, nasal fossae, paranasal sinuses, and orbits, computed tomography can readily demonstrate the extent and boundaries of the lesion.

Mucoepidermoid carcinoma in a young adult: recognition, diagnosis, and treatment and responsibility.

Recognizing an abnormality is the first and most essential step when diagnosing a pathosis. All health care providers are responsible for evaluating suspicious symptoms and clinical and laboratory findings. Without a baseline evaluation, dentists cannot guarantee that patients are free of potentially serious disease. This article documents how the prognosis for and morbidity of cancer therapy may have been affected by the failure to recognize abnormal signs. Professional responsibility and liability for recognition of abnormality and subsequent diagnosis is emphasized.

[Carcinoma in a 40-year chronic oro-antral communication].

A squamous cell carcinoma developed in a 66 year old patient in the region of a traumatically caused oro-antral fistula that has persisted for 40 years. The clinical course and histological findings are presented. Based on the few case reports in the literature the occurrence of malignancies in chronic traumatic fistulae is discussed. Reference is also made to causal relationships between such a fistula and malignancy under the aspect of forensic medical consultations.

[Maxillary ameloblastoma. Apropos of a case and review of the literature].

Although ameloblastoma is one of the benign odontogenic tumors, the maxillary localisations often grow more infiltratively and show higher recurrency than the mandibular localisations. The authors report a case of ameloblastoma in maxillary sinus and sketch out the operative methods with a literature review.
