Anatomic and Radiographic Studies on the Parana- sal Sinuses of the Buffalo in Egypt (Bos bubalis, L.)

This survey was applied on the pa- ranasal sinuses of the Buffalo in Egypt (Bos bubalis L.) and its surgi- cal approach. Ten adult buffaloe heads of ages ranging between 2 -7 years were used. Six of these heads were used for dry skull preparation while the other four were used for radiography and cross sections. The study concluded that, in addition to sinuses conchales, four paranasal sinuses have been found to occur in adult buffalo comprising the sinus frontalis, sinus maxillaris, sinus palatinus and sinus lacrimalis. The anatomical and radiographic description of these paranasal sinuses as well as its dimensions and communications has been mentioned. Two sites for trephination of the frontal sinus could be indicated.Trephining the rostral frontal sinus through was indicated at the middle of a transverse line extending between the caudal margins of the orbital rim to the median plane while trephination site to gain the caudal frontal sinus was indicated at the middle of another transverse line extending from the middle of the base the horn to the median plane. Surgical approach of the maxillary sinus for trephining could be indicated on a vertical line extending upward from the caudal margin of the 2nd premolar for about 4.0-4.5 cm.
