Journal Title: Journal of Evidence Based Medicine and Healthcare - Year 2014, Vol 1, Issue 7
Abstract
Maxillary sinus develops during late fetal life as a diverticulum in the lateral nasal wall, the opening of the diverticulum present as the orifice of the sinus called primary maxillary sinus ostium (PMO). OBJECTIVES: To find out the position of Primary maxillary sinus ostium in the hiatus semilunaris. MATERIALS AND METHODS: Total of fifty cadaver specimens (32 male & 18 female) in which primary maxillary sinus ostium is identified and location is noted. RESULTS: Primary maxillary sinus ostium is present in the posterior 1/3 of hiatus semilunaris in 60% of specimens, which is the commonest type of presentation, middle 1/3 of hiatus semilunaris in 22% of specimens, anterior 1/3 of hiatus semilunaris in 14% of specimens and absent in 4% of specimens. CONCLUSION: The knowledge about the position of primary maxillary sinus ostium is important for the surgeons to prevent complications when doing endoscopic sinus surgery.
