ABSTRACT
During the period from 1989 to 1999 at Cho Ray hospital we have a series of 27 patients with unilateral paranasal sinus malignancies who were underwent the maxillectomy. The ipsilateral temporal muscle was used for one-stage primary reconstruction of the hard palate or orbital floor or both after the ablation of the tumor. Results: in this series, there are 8 T3 tumors and 19 T4 tumors. 22 temporal muscle flaps have been used for reconstruction of the hard palate and orbital floor have been reconstructed simultaneously. All flaps were good. We have neither flap related complication nor partial or total flap loss. The new hard palate flaps separated well the oral cavity and the nasal fossa and could maintain the eye ball in a good position. The patients could eat and drink by mouth just after the surgery. The flaps resist well to the following radiation therapy. No flap demonstrated any degree of radionecrosis.
