| Popis: | We examined the postoperative masticatory and articulatory function of 21 cases who underwent surgical treatment for malignant tumors of maxillary sinuses at Kobe University Hospital. Ten of these cases underwent maxillectomy or extended maxillectomy without reconstruction except for the orbital floor (non-reconstruction group), three were treated with maxillary reconstruction using rectus abdominis myocutaneous flaps after maxillectomy or extended maxillectomy (reconstruction group), and eight were given irradiation, intraarterial infusion chemotherapy and curettage of the necrotic tumor (combined therapy group). The masticatory and articulatory function were examined by means of questionnaires. The masticatory function was further assessed with the low-adhesive, color-developing, chewing-gum method (chewing gum test), and the articulatory function was also evaluated with the intelligibility for 100 monosyllables (intelligibility test). The responses to the questionnaires demonstrated that all of them could take a normal diet, and that none of them needed writing as an aid to conversation. The chewing gum test showed that mastication was less satisfactory for the non-reconstruction and combined therapy groups than for the reconstruction group. The intelligibility score of 100 monosyllables was 75% for the reconctruction group, 69.9% for the combined therapy group, and 49 .5% for the nonreconstruction group. Although the superior masticatory and articulatory functions of the reconstruction group were demonstrated in this study, recurrences are hard to assess because the musculocutaneous flap is filled up in this modality. As the postoperative masticatory and articulatory functions were better than we expected, we conclude that patients with malignant tumors in maxillary sinuses should undergo en-bloc resection without reconstruction. |
