| Abstract | ||
| • Anatomical variations of PNS are numerous and confusing. Careful examination by MDCT is required to avoid intraoperative complications. The development of maxillary sinus is completed at the age of puberty, before which we can’t comment on the sinus size. • In our thesis we studied types of small maxillary sinus; silent sinus syndrome and hypoplastic maxillary sinus. Both are mostly discovered incidentally and not necessarily associated with sinusitis especially SSS. The radiological features of SSS are collapse of the sinus walls due to chronic outflow obstruction with resultant increased orbit size and middle meatus with laterally bent uncinate process. Radiologically MSH was defined as small sinus didn’t develop its alveolar recess with thick sinus walls. The position of UP and the orbit size were not significantly changed. AIM OF THE WORK • This study aimed to study of the role of MDCT in the assessment of the effect of different anatomical types of frontal air cells on the occurrence and severity of frontal sinusitis. | ||
