HERNANDEZ CORTES, Katherine; QUERALTA MARZAN, Vivian  y  HERNANDEZ CORTES, Nelsa. Anatomical variations of frontal sinuses in skull radiographs of patients with brachycephalic skulls. Rev Cubana Invest Bioméd [online]. 2020, vol.39, n.1, e374.  Epub 01-Mar-2020. ISSN 0864-0300.

Introduction:

The bone anatomy of paranasal cavities presents a large number of variants which may be the cause of or predisposing factor for rhinosinus disease, among which are asymmetry and agenesis. These may be very important hurdles in nasal endoscopic surgery and often require medical care.

Objective:

Determine the anatomical variations in the frontal sinuses of patients with brachycephalic skulls not diagnosed with rhinosinus disease.

Methods:

A cross-sectional observational descriptive study was conducted of frontal sinus longitudinal and transverse diameters of frontal sinuses based on AP skull radiographs of 28 patients with brachycephalic skulls attending the imaging service of Juan Bruno Zayas Alfonso Hospital from January to February 2019.

Result:

Identification was made of the main frontal sinus variations in skull radiographs and their behavior according to epidemiological variables.

Conclusions:

The 19-29 years age group prevailed, with 9 patients (32.1%). There was a slight predominance of men versus women. Ten (35.7%) patients had bilateral agenesis and 3 (10.7%) had unilateral left agenesis. The magnitudes for right cavities were greater than those for left cavities. The frontal sinuses studied were asymmetrical in terms of size and position.

Palabras clave : frontal sinuses; anatomical variants; agenesis; asymmetry; radiographs.
