[Glomus caroticum, jugulare and vagale--problems in diagnosis and treatment].

INTRODUCTION: The paraganglia tissue in 80% is located in suprarenal glands. The rest (20%) are with close association with autonomic nerves and some cranial nerves. Paraganglioma, being tumors arising from the paraganglion cells of the parasympathetic system, were first reported in man in 1935. Although histologically these tumors have been shown to contain neurosecretory granules, they are rarely functional. There are four kinds of paragangliomas: deriving from carotid artery baroreceptors (glomus caroticum), internal jugular vein (glomus jugulare); placed along vagal nerve (glomus vagale) and paragangliomas of tympanic cavity (glomus tympanicum). The first three of them are clinically recognized as tumor of the neck. MATERIAL AND METHODS: Authors present group of 7 patients with paragangliomas treated in ENT Department in Poznań in the years 1994-2004. There were treated 4 patients with glomus caroticum, two with glomus vagale and one patient with glomus jugulare. RESULTS: All patients were treated surgically. In one case in group with glomus caroticum in histological examination tendency to infiltration of internal carotid artery was stated (chemodectoma malignum). The tumor was removed totally with partial excision of communis, external and internal carotid artery. The internal carotid artery was closed by the tumor. CONCLUSION: Authors underline three aspects of process of treatment in whole group of patients: diagnostic problems, way of treatment and long term results.

[Deep lobe of parotid gland tumors].

INTRODUCTION: Surgery of the parotid gland tumors can be difficult because of the presence of the facial nerve branches in the parotid tissue. The aim of the surgical treatment is complete removal of the tumor without damaging the facial nerve. There are several surgical techniques to expose the main trunk and the branches of the facial nerve. On the other hand during the surgery the nerve function is continuously observed by using facial nerve monitor. MATERIAL AND METHODS: In the years of 2002-2004 208 patients with the parotid gland tumors were treated. There were 177 benign and 31 malignant tumors. 159 tumors were located in the superficial lobe of the parotid gland, 35 in the superficial and the deep lobe, and 14 only in the deep lobe. All patients were treated surgically. RESULTS: In cases concerning the operations of the tumors located in the deep lobe, the facial nerve branches had to be exposed with help of the microscopic operating techniques. All tumors were removed totally. A paralysis of the facial nerve was observed in two cases of the pleomorhic adenoma with a diameter over 6 cm, and in 9 cases of malignant tumors of the superficial and the deep lobe, where the main trunk or the branches of the facial nerve were integrated with the tumor mass. CONCLUSION: Surgical treatment of the parotid gland tumors presented in our study demonstrates good results. The risk of facial nerve paresis is higher in malignant tumors and big pleomorphic adenomas.

[Rare case of the Recklinghausen disease in the head and neck region].

INTRODUCTION: Neurofibromatosis type I (Recklinghausen disease) is one of the most common genetic disorders. Symptoms in head and neck region are present in nearly 30% of cases, but the most frequent are skin café-au-lait lesions or lesions localized in craniofacial region. Neurinomas of the last four cranial nerves are also described. MATERIAL AND METHODS: We discuss a case of a 50-year woman admitted to our department because of chronic pain symptoms localized in the head and neck region. A rare case of neurinoma of the X and XII nerves in the neck region was stated. This patient was successfully treated surgically with removing tumors, which involved vagal and hypoglossal nerve on the right side. CONCLUSIONS: The causal treatment is until now unknown and patients are carefully observed and scan with MRI. The possible treatment for patients are surgery when the lesion become painful or for cosmetic reasons. Also surgery with radiotherapy is require for tumors with malignant transformation which is possible in 5% of cases. The genetic guidance should be proposed to NF1 patients.

[The assessment of intravital staining of parotic gland using methylene blue in the surgery of benign gland tumors--preliminary report].

INTRODUCTION: The operation of parotic gland tumors are challenge for the surgeon. The main aim of these operations is tumor removal and facial nerve preservation. Despite of imaging examinations, showing the localization of the tumor, it's important for surgeon to have the opportunity to discriminate between tumor and normal parotic gland tissue during the operation, e.g. in color difference. Methylene blue (MB) has been used in intravital staining of various tissues for a long time. MATERIAL AND METHODS: The aim of the study was an attempt of intravital staining of parotic gland, using MB during the surgery of five benign gland tumors. RESULTS: In all cases parenchyma of the parotic gland was dark-blue stained and in all cases, while the tumor didn't show any staining. CONCLUSIONS: Using of MB may be useful in the surgery of parotic gland.

[Functional endoscopic sinus surgery assisted by navigation system--own experience].

Functional endoscopic sinus surgery is nowadays a gold standard in case of chronic sinusitis. Microscopes and endoscopes are routinely used and the plan of the operation is based on physical examination and high resolution computed tomography of paranasal sinuses done in the bone frame. In the last few years trials were done with intraoperative navigation systems. This kind of system was tested in the ENT department of Karol Marcinkowski University in Poznań. Surgery was performed using electromagnetic and optical one. Thirteen patients with chronic sinusitis underwent surgery. A high resolution computed tomography was done in three planes. Then the data were transferred to the computer system. Those data were used to plan the surgery (determination of the "safe corridor") and in the intraoperative monitoring of the position of surgical instruments. We can state an improvement of the comfort for the surgeon and safety for the patient. We did not state disturbances in system work due to patient displacement during surgery. Accuracy and rapidity of the computer system allowed to perform safe surgery. Authors accentuate the usability of this system in case of reoperation, extensive pathological changes and in congenital malformations.
