The introduction of minimally invasive surgical procedures has significantly reduced the rate of major salivary gland removal due to sialolithiasis. The aim of this study is to assess the effectiveness of sialoendoscopy, rate of salivary fistula or natural ostium stenosis in parotid sialolithiasis treatment. The endpoint was to analyse the efficiency of a(More)
Head and neck paragangliomas are tumors arising from specialized neural crest cells. Prominent locations are the carotid body along with the vagal, jugular, and tympanic glomus. Head and neck paragangliomas are slowly growing tumors, with some carotid body tumors being reported to exist for many years as a painless lateral mass on the neck. Symptoms depend(More)
INTRODUCTION The purpose of the study was to evaluate salivary gland dysfunction after a high-dose radioiodine therapy administered to patients with differentiated thyroid carcinoma. MATERIAL AND METHODS The study group consisted of 60 patients (age range 20-78 years). Detailed history about complaints from the oral cavity were taken, followed by the(More)
BACKGROUND The aim of the study was to evaluate the treatment outcomes in the group of 108 T1b glottic cancer patients with the anterior commissure involvement treated with open horizontal glottectomy and to compare them with transoral laser microsurgery (TLM) or primary radiotherapy (XRT) results from the literature review. METHODS Status of surgical(More)
Our aim was to analyse the nature of a sialendoscopy-based classification and present its use in the treatment of stenoses of Wharton's and Stensen's ducts. The classification of stenoses of Wharton's duct has not been published before. We did 133 sialendoscopies in 114 patients who presented with possible obstruction of the ducts to the tertiary centre for(More)
Neoplasm of salivary gland constitutes about 3% of all tumours of head and neck. Within the category we can differentiate tumours of a very different histological structure. What lies behind such great differences in the changes within the salivary glands is complex embryogenesis of the glands. This work aims at the assessment of the frequency of occurrence(More)
OBJECTIVES PRAME (Preferentially Expressed Antigen in Melanoma) is a tumor-associated antigen recognized by immunocytes, and it induces cytotoxic T cell-mediated responses in melanoma. PRAME expression in tumors interferes with retinoic acid receptor (RAR) signaling thus promoting tumor progression. Here, we study PRAME expression in head and neck squamous(More)
The aim of the study was to assess salivary gland parenchyma by means of sonoelastography in patients irradiated for head and neck squamous cell carcinoma (HNSCC). The studied group consisted of 52 patients after radiotherapy (RT) and 54 healthy volunteers. All of the former were treated for advanced larynx (40), oropharynx (9), or maxilla (3) squamous(More)
The objectives of this article are to assess the frequency and significance of facial paralysis and undiagnosed nerve infiltration in patients with parotid malignancies. 103 patients with parotid gland malignancies were treated in a single institution, the tertiary center for ENT at the University Department in Poznan between 1996 and 2006. Facial palsy at(More)
Our research was conducted to determine the algorithm changes during the treatment of submandibular sialolithiasis. Two time periods were compared between 2004–2008 and 2009–2012. The turning point was December 2008, when sialendoscopy procedure was introduced. In the first period, 48 patients were treated: 31 outpatient duct incisions with stone evacuation(More)
