[Otoacoustic emission evaluation in patients with tinnitus]. / Badanie otoemisji akustycznych u chorych z szumami usznymi.

Analysis of otoacoustic emission is highly objective, noninvasive and sensitive method representing cochlear function. In The Centre of ENT Rehabilitation in Poznan more than 900 patients were evaluated because of tinnitus. Standard tests were broaden by otoacoustic emission (SOAE, TEOAE, DPOAE) and results are discussed. Our results suggest that otoacoustic emission is possible to record in normally or with moderate hearing loss patients. 18 patients had SOAE. Only 2 patients had the same frequency of SOAE and tinnitus.

[Value of intraoral ultrasonography in diagnosis of tonsillar tumors]. / Wartosc endoskopowego badania ultrasonograficznego w diagnostyce guzów migdalka podniebiennego.

UNLABELLED: Aim of the study was to establish clinical utility of intraoral ultrasonography in diagnosis of tonsillar tumours in respect to its magnitude, location, histological structure, presence of satellite lesions and furthermore compare results obtained by endoral to transcutaneous ultrasonography. 64 patients with tonsillar tumour entered the study. Endoral ultrasonography was performed by probe UST-937 Convex 5 MHz. CONCLUSION: Endoral ultrasonography is very efficient in exact tumour localisation and correlation between endoral ultrasonography and intraoperative assessment of T tumor is statistically significant. Ultrasonography is sensitive in recognition of satellite lesions. In the case of planoepithelial cancer, malignant lymphoma and inflammatory process very characteristic features of tumor can be described. Endoral ultrasonography is better then transcutaneous in tonsillar tumours diagnosis.

[Diagnostic difficulties in nasopharyngeal tumors]. / Trudnosci diagnostyczne w rozpoznawaniu guzów czesci nosowej gardla.

Diagnostic possibilities in lethal midline granuloma (Wegener's granulomatosis, angiocentric lymphoma) based on the literature were presented. Results of diagnostic examinations in a case of 34 years old man admitted to the Dept. of Otolaryngology in Poznan were described.

[Tracheoesophageal fistula after the removal of esophageal foreign body]. / Przetoka tchawiczo-przelykowa po usunieciu ciala obcego przelyku.

A case of 18 years old male with tracheoesophageal fistula as a result of esophageal foreign body (chestnut) is described. Foreign body was removed using esophagoscopy. Bronchofiberoscopy performed because of difficulties with swallowing and frequent airway infections revealed tracheoesophageal fistula. Fistula was closed from intratracheal access. Symptoms of dysfagia disappeared after surgery.

[Liposarcoma of the neck]. / Tluszczakomiesak szyi.

Liposarcoma is a malignant neoplasm of soft tissue. Its occurrence in the head and neck region is extremely rare. The case of a 26-year-old woman with neck liposarcoma is presented. The clinical manifestation, histopathology, possibility and results of the tumor treatment are described according to the literature.

[Endoscopic ultrasound probe applications for diagnosis of the oral cavity and throat tumors]. / Zastosowanie glowicy endoskopowej w diagnostyce ultrasonograficznej Guzów jamy ustnej i gardla.

Assessment of neoplastic lesions situated inside palatinal tonsils and tongue may cause a lot of difficulties. Bringing into practice diagnostic tools such as: transcutaneous ultrasound, CT, MRI have met numerous limitations and obstacles. Apart from restrictions set by anatomical borders, other drawbacks of methods mentioned above are: high cost of single examination, expensive equipment and difficulties of access. In this paper the results of examination of 20 tongue tumors and 23 tonsil tumors carried out by means of endoral ultrasound are presented. Endoral ultrasound provided evaluation of size, localisation, extension and delimitation of and detect small nodules satellite to the predominant tumor mass. Evaluation of lesion echostructure enables to differentiate the tumor nature and advises to plan other diagnostic procedures.
