tion to the osteomeatal area was made with the endin-view of using the data for clinical application in TURBINATES + L E N'G T H doing cannulation of the maxillary ostium and with the use of a modified cannula specifically designed 1. Inferior for Filipinos in a future study. 2. Middle 3. Superior 4. Supreme MATERIALS AND METHODS Filipino adult cadavers from the Department of Anatomy, UP College of Medicine were studied paying INFERIOR MEATUS: particular attention to the lateral nasal wall. Sagittal skull sections were clone as well as coronal sections Distance of the nasolacrimal duct ostium to the when needed. Actual measurements were made using anterior portion of the inferior concha: ram. a Vernier caliper and recorded on the prepared observation sheets (see Appendix I). Anatomic Diameteroftheostium: ram. variations observed were likewise noted. Data were recorded and analyzed using a microstat computer Variations in the size, shape and position of the program (IBM). Measurements on the left side were opening of the nasolacrimal duct: compared with the eight to note any significant difference. RESULTS Table 1 shows the measurements of the different anatomic structures in the lateral nasal wall in this study (Figures 1, 2, and 3). ....'...... .: .....', ."/i, ': '_ ....'
