AN ANATOMICAL STUDY ON LOCATION OF MAXILLARY SINUS OSTIUM AND IT' S SURGICAL IMPORTANCE
Author: Jyothi N. Nayak, Varalakshmi K. L., Sangeetha M., Shilpa Naik
Background: A clear knowledge of exact location of maxillary sinus openings is essential for the endoscopic sinus surgeons as it is related to important structures like orbital floor, ethmoidal infundibulum and the nasolacrimal duct. Aim: The principle maxillary ostium is opened in the hiatus semilunaris which is located on the upper part of medial wall of maxillary inus. Materials and Methods: This study was carried in 52 sagitally cut head and neck specimens from the Department of anatomy,
MVJ Medical College and Research Hospital. RESULT: In the present study, maxillary sinus ostium was more commonly opened in to the posterior third of the hiatus semilunaris in 33(63.46%) specimens, middle third of hiatus semilunaris in 13(25%) specimens, anterior third in 5(9.61%) and absent in 1 (1.9%)specimens. Accessory maxillary ostium was found in 6(18.75%) specimens, which opened into the membranous meatus inferior to the uncinate process. Conclusion: This study will be helpful for surgeons to prevent the complications while performing endoscopic sinus surgery.
