The aim of this research was to analyze the influence of epidemiological factors in patients with laryngeal carcinoma treated by surgery, radiotherapy or therapeutic associations.

Objective: To correlate sleep quality with the severity of the patients effort to polysomnography. Methods: A random sample of 15 adult patients of both genders, aged 29-68 years, who were referred for polysomnography examination at a hospital in the city of Porto Alegre / RS, Brazil, were randomly selected.

Cystic cervical lymph nodes are a rare anatomo-clinical form. They are a typical presentation of metastasis of cancers of the waldeyer ring in particular those of the palatine tonsil. Nevertheless, they may reveal a papillary carcinoma of the thyroid even though the thyroid gland is clinically normal. In this case the combination of ultrasound and fine needle aspiration cytology (FNAC) with intranodal thyroglobulin dosage allows to differentiate lymphadenopathies of thyroid origin from other causes. We report the case of a 40-year-old patient received in December 2015 in our hospital for cystic cervical lymph nodes without clinical thyroid mass. FNAC was for a metastasis of an adenocarcinoma.

Osteoma is a rare benign lesion of the skull, with an incidence of 0.6% of all benign tumours of paranasal sinuses. It is commonly asymptomatic, and mostly diagnosed incidentally at the imaging. The most frequent disturbs are: headache, nasal discharge and symptoms of inflammation.

Importance: The cartilagineous nasal septum remains a difficult structure to straighten and to stabilize as it tends to bend. Recurrence of an asymmetric and bent septum is a frequent complain in patients as it may lead to asymmetric nasal breathing and/or aesthetic asymmetries of the shape of the nose.

Objectives: An unusual left parapharyngeal ganglioneuroma case was discussed in the context of diagnostic difficulties, surgical tricks and Horner syndrome as a main surgical complication.
