Answer 26

YES: SMITH 1995

Question 27

what is the major artery to take care during a total mandibulectomy?

Answer 27

inferior alveolar artery if caudal mandibulectomy is performed

inferior alveolar artery has to be ligated if rostral mandibulactomy is performed in the mandibular canal

Question 28

major artery to take care during caudal maxillectomies

Answer 28

major palatine artery

Question 28

major artery to take care during caudal maxillectomies

Answer 28

major palatine artery

Question 29

what muscle need to be incised to provide exposure of the rostral part of the sublingual salivary gland?

Answer 29

milohyoideus muscle.

Question 30

Name muscle under wich remnant mandibular-sublingual salivary complex gland need to go

Answer 30

digastricus muscle

Question 31

what nerve usually delimitate the cranial exposure necessary for complete removal of mandibular-sublingual salivary gland complex? in what cases is necessary to go even more rostrally?

Answer 31

lingual nerve.

If a ranula is present, however, dissection should continue rostral to the lingual nerve under the mylohyoideus to remove all of the glandular tissue up to the sublingual caruncle
