Background

•The midfacial defects

reconstructions for oncologic

resections are a surgical challenge

Mc Carthy C, Cordeiro P et al. Plast. Reconstr. Surg. 2010; 126:1947-59

IPRAS 2013

Background

•The maxillar provide the structural support between skull base and maxillary arches.

•To separate oral and nasal cavities.

•To participate in swallowing, phonation, mastication, vision and aesthetic appearance.

IPRAS 2013

Background•Generally we need to realize the

maxillectomy associated with soft tissue resection.

•This results in different functional impairments

•The maxillary reconstruction going from obturator prosthesis, local flaps to free flaps.Algorithm and Outcomes: 15-year Review of Midface Reconstruction. Plast. Reconstr.

Aim

•To present the different

reconstructives alternatives

used after a maxillectomy for

oncologic disease in our

hospital.

Method

•Retrospective analysis of all patients that was submitted to a maxillectomy for oncologic disease between 2008 and 2011 in our center

•Medical record review.

•Clinical control

Method

•Complications

•Perioperative < 30 days after

surgery

•Late > 30 days after surgery

Results•In all patients we achieve a

satisfactory functional outcome

•Complications

•Aspirative pneumonia in two patients.

•Partial necrosis of latissimus dorsi flap

•venous thrombosis

IPRAS 2013

Discussion•Is recommended to adjust the

reconstructive choice to

•Maxillectomy realized

•Age

•TNM

•Comorbidities

•Functional outcomes

IPRAS 2013

Discussion

•The obturator prosthesis can

be reserve for selected

patients with limited palatal

defects.

IPRAS 2013

Discussion

•The unilateral or bilateral

temporalis muscle flap is

recommended and presents

adequate functional outcome in

patients with advanced disease

and poor prognosis.

IPRAS 2013

Discussion•The microsurgical reconstruction

is the surgical alternative of

choice, with the best funcional

and aesthetics outcomes in

patients with type II - III - IV

maxillectomies
