Position statement of the Brazilian Academy of Rhinology on the use of antihistamines, antileukotrienes, and oral corticosteroids in the treatment of inflammatory sinonasal diseases.

Introduction: Inflammatory conditions of the nose and paranasal sinuses are very prevalent in the general population, resulting in marked loss of quality of life in affected patients, as well as significant work, leisure, and social activity losses. These patients require specific and specialized treatment. A wide range of oral medications are available.

Setting of an endoscopic nasal reference point for surgical access to the anterior base through an anatomical study on cadavers.

Introduction: Diseases of paranasal sinuses, nasal cavity, and skull base can be treated by endonasal operations using a nasal rigid endoscope. When conducting this kind of surgery, anatomical references are critical for safety.

Objective: To measure the distance from the posterior wall of the maxillary sinus to the skull base, according to socio-demographic characteristics, and to detail an anatomical reference point for paranasal sinus operations and for an access to the anterior skull base, comparing anatomical variations between right and left sides, gender, height, weight, age, and ethnicity in cadavers.

Reproducibility of the three-dimensional endoscopic staging system for nasal polyposis.

Unlabelled: Nasal polyposis is a chronic inflammatory process of the nasal mucosa, characterized by multiple and bilateral nasal polyps. Different drugs have been used in its treatment. In order to study the results of different treatment modalities it is necessary to have some kind of staging.

Absence of nasal air flow and maxillary sinus development.

Unlabelled: Paranasal sinuses development mechanisms are not well known. Nasal air flow, according to one of the proposed theories, would be fundamental to the growth and healthy development of paranasal sinuses.

Aim: The aim of this study was to evaluate the maxillary sinus growth and health in the presence and absence of postnasal air flow through a unique model.
