The anatomy research of expanding vision of endoscopic maxillary sinus operation / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To get the anatomical method of expanding vision of endoscopic maxillary sinus operation to providing guidance for the satisfactory surgical vision by measurement of nasal cavity and maxillary sinus relative structure.@*METHOD@#By anatomical measurement from 30 human cranium preparations (21 male, 9 female), which were marinated by 10% formaldehyde solution, we tried to find out anatomical factors that influence expanding vision of endoscopic maxillary sinus operation.@*RESULT@#Measurement of cranium preparations respective distance between bone nasolacrimal canal anterior wall superior extremity, central extremity, bottom extremity and borderline of maxillary sinus anterior wall and medial wall were 0 mm, (1.90 +/- l.03) mm, (3.29 +/- 1.04) mm. Distance between anterior inferior part of bone nasolacrimal canal and anterior edge of inferior concha was (5.13 +/- 0.62) mm, and vertical distance between anterior inferior part of bone nasolacrimal canal and nasal bottom was (16.89 +/- 0.97) mm. The difference between right and left side had no significant statistic sense (P > 0.05). Removal of the bone area the upper and lower diameter of part of the inferior turbinate attachment was (9.43 +/- 1.72) mm, anteroposterior diameter from top to bottom was (9.76 +/- 0.83) mm, (11.39 +/- 0.50) mm, (12.85 +/- 0.66) mm, the upper and lower diameter of the following part of the inferior turbinate attachment was (13.52 +/- 0.83) mm, anteroposterior diameter from top to bottom was (19.89 +/- 1.37) mm, (16.59 +/- 0.77) mm, (12.48 +/- 0.91) mm.@*CONCLUSION@#Dissection from inferior turbinate anterior part approach to maxillary sinus could expand the endoscopic operation vision.
