Anatomia cirúrgica do acesso nasal transesfenoidal para tumores da hipófise

Surgical anatomy of the nasal transphenoidal approach for pituitary tumors

Resumos

Foram analisadas diferentes medidas relacionadas ao acesso nasal transesfenoidal em 18 hemicabeças de cadáveres com o objetivo de estudar os limites e vantagens dessa via. Foram obtidos os seguintes valores médios (mm) para as principais medidas: diâmetro maior da narina 15,18; altura da cavidade nasal 44,11; distância narina - sela turca 71,71. Esses valores demonstram ser o acesso nasal uma via ampla e direta à sela turca. O presente estudo demonstrou também ser possível nesse acesso preservar o septo cartilágino e outras estruturas que são usualmente lesadas no acesso sublabial.

Different distances related to the nasal transphenoidal approach were measured on the hemiheads of eighteen cadavers in order to study its limits and advantages. The main mean measures obtained (mm) were: major diameter of the nostril 15.18; height of the nasal cavity 44.11; nostril-sella turcica distance 71.71. These results show that the nasal approach is wide and direct to the sella turcica. The present study demonstrate the possibility of preservation of the cartilaginous septum and other structures which are usually damaged when the sublabial approach is employed.

ABSTRACT

Different distances related to the nasal transphenoidal approach were measured on the hemiheads of eighteen cadavers in order to study its limits and advantages. The main mean measures obtained (mm) were: major diameter of the nostril 15.18; height of the nasal cavity 44.11; nostril-sella turcica distance 71.71. These results show that the nasal approach is wide and direct to the sella turcica. The present study demonstrate the possibility of preservation of the cartilaginous septum and other structures which are usually damaged when the sublabial approach is employed.

Key words: surgical anatomy, nasal transphenoidal approach, pituitary gland.
