Cadaver Studies of the Anatomy of Arterial Supply to the Inferior Turbinates

Abstract

The anatomy of the arterial supply of the inferior turbinate was studied by dissection and serial histological sections. The arrangement was found to be constant, with a single main descending branch of the sphenopalatine artery entering its substance from above, 1–1.5 cm from its posterior border. This artery branches as it passes forwards within the turbinate, remaining close to the bone. As these pass anteriorly they give rise to arterial arcades which remain close to or within the bone, with the main artery increasing in diameter. The implications of these findings are discussed in a surgical context.

The posterior pedicled inferior turbinate–nasoseptal flap: a potential combined flap for skull base reconstruction

“…Our findings regarding the network distribution of anastomosing branches of the ITAs and NSAs were in accord with previous reports [2,5,9,13,18,22]. (The PNSA originated from sphenopalatine artery, which passed under the mucoperiosteum between the sphenopalatine foramen and the nasal septum below sphenoidal ostium.…”

“…If the two flaps could be harvested as a combination flap, it definitely would overcome the deficiencies of the small covering area of a single flap. The vascularization of the inferior turbinate and the nasal septum were clearly clarified [2,5,9,13,18,22], but it is unclear if there exists consistent anastomosis between the inferior turbinate artery and the nasoseptal artery. This report provides the first English-language descriptions of the existence of these AAs and developed an endonasal flap-the PPITNF.…”

A Comparative Study of Different Methods of Treatment for Inferior Turbinate Hypertrophy

“…Three locations along the medial surface are generally used. 8 Partial turbinectomy: The clamp is placed over the anterior inferior two-thirds or less of the turbinate. The clamp is left there for 2 to 3 minutes and then released.…”

“…This will decrease the incidence of postoperative bleeding and obviate the need for the packing the nose. 8 Turbinoplasty: After medialization of the turbinate, an L-shaped incision is made at its lateral-inferior margin. A mucosal flap is elevated and part of the turbinate bone and parenchyma is resected as required.…”

The clinical value of the novel cauterization procedure for the inferior turbinate artery during turbinate surgery

“…We have not encountered such a complication in our study group. As we know from the previous studies, there are contributions to the blood supply of the inferior turbinate from the other arteries such as facial artery [2,7]. In addition, recanalization of the cauterized inferior turbinate artery or sustained blood supply might be the other contributing factors.…”
