Repair of subtotal tympanic membrane perforations with Seprafilm.

OBJECTIVES: We studied the experimental use of Seprafilm, a sheet-like film form of hyaluronic acid, in the repair of subtotal perforations of the tympanic membrane (TM), and the durability of such repairs. METHOD: The research was conducted on 42 Sprague-Dawley rats. Right TMs of all rats were subtotally and thermally perforated in the same fashion. Seprafilm was applied to the perforated TMs of the 21 rats comprising the experiment group. The perforated TMs of the remaining 21 rats, the control group, were left to heal spontaneously. RESULTS: The mean healing times were recorded as 7.8 +/- 0.6 days for the Seprafilm group and 14.9 +/- 1.1 days for the control group (p < 0.001). CONCLUSIONS: These results suggest that Seprafilm may be a possible first choice (before the decision to operate) in subtotal perforations, considering its easy application and patient follow-up.

Comparison of computed tomography and magnetic resonance imaging in the diagnosis of parotid tumors.

OBJECTIVE: The role of computed tomography (CT) and magnetic resonance imaging (MRI) in the diagnosis of parotid tumors was investigated. METHODS: Forty patients with the clinical suspicion of a parotid mass underwent both CT and MRI of the parotid region. Two radiologists independently assessed the CT and MRI results with respect to tumor localization, tumor margin characteristics, and infiltration of surrounding tissue. Histopathologic specimens were obtained in all cases and correlated with the radiologic findings. RESULTS: The sensitivity and specificity of CT and MRI were nearly the same for tumor location, tumor margin, and tumor infiltration. CONCLUSION: The 2 imaging techniques provided the same information with respect to the presurgical planning and contribute to the diagnosis and therapy planning of parotid tumors.

Proboscis lateralis: radiological evaluation.

Proboscis lateralis is a rare craniofacial anomaly. It consists of a soft, trunk-like process that originates from the medial portion of the orbital roof and it may be accompanied by a number of facial and cerebral anomalies. The characteristics and relationship of the lesion to adjacent structures should be known, and associated anomalies should be detected before surgical correction. The patient should undergo neuroimaging studies besides clinical evaluation to obtain this information in detail. The neuroimaging findings of only one previous case are available in the literature. We report two cases of proboscis lateralis evaluated by CT and MRI before corrective surgery.
