Applicatio Of Posterolateral Approach In Resection Of Maxilla

BackgroundAt present, there are disadvantages and advantages of all kinds of approaches during themaxilla resection, most of which have different problems after surgery, such as impediment inmastication, speaking and deglutition, in particular the bad influence of appearance. Besides,during the radiotherapy of traditional interior incision perioperation, holes appear. In order todecrease the scar of skin tissue left after surgery and the possible occurrence of disfigured holesemerged during the radiotherapy of traditional interior incision perioperative period and promotepatient's life quality, it is inevitable and necessary to develop and initiate a new kind of approachthat is more suitable for the maxillectomy.ObjectiveAccording to the anatomy characteristics of maxilla and skin tissue, posterior lateral approachof maxilla resection is designed and set forth. From the clinical experience, premiercomprehensive evaluation will be made to this approach.MethodOn the basis of the analysis and comments of the current approach in accordance withdesigning principles of the head and neck's surgery approach, a new approach of maxillaresection is developed, which starts from angulus oculi medialis, then inferior lower eyelidinferior,anterior ansa capitis, hair boundary, anterior antilobium, lower earlobe, posteriorinferior angulus mandibulae, then ends in the lower limb of mandibula. In this article, the clinical materials of 8 patients who have come through the maxillectomy of malignancy in this approachwill be reviewed and analyzed and a premier clinical conclusion will be made.ResultNone of the patients die in the perioperation. The surgery incision heals up quite well in thefirst period, the scar left on the face after operation is apparently lessened; the situation of facialsubsiding remains and the eyesight of those with eyeballs are good. In one case, a hole of about1*0.5cm connected with the nasal cavity appears in the right palate after one month of thesurgery. In another case, the right eye of the patient has slight diplopia problem after 3 months,which, though, has been cure after conservative treatment. In another case, it recrudesces after 7months.ConclusionPosterior lateral approach of maxilla resection works with its clinical operation values.Compared with the current approaches, it distinguished itself from the others from several aspect,such as larger view of surgery operation, lessened scars left on the face for its hidden surgeryposition, easier reconstruction of maxilla and optional radical neck dissection in the sameoperation view when the lower-part incision approach is changed a bit and theoretical decreaseof the disfigured holes'appearance in the central facial part of the interior incision inperioperation. However, it has disadvantages like significant wound left. This approach enrichesand develops the approachs of the maxillectomy, providing various operational choice forpatients that need maxilla resection more personally.
