Surgical Treatment of Maxillary Antrum Neoplasms

Abstract

Paranasal sinus cancers comprise about 0.3% of all cancers and 80% of these lesions arise in the maxillary sinus. A masquerading primary sinus tumour represents a therapeutic challenge as most patients with maxillary antrum cancer are diagnosed with advanced disease. However, distant metastases rarely occur. We examined the clinical outcome of patients with antrum neoplasms. Medical records were obtained for all patients diagnosed with a sinus malignancy between July 2009 and January 2014. During this period, 41 patients with maxillary tumours were treated, among which 9 patients received a maxillectomy. There were 21 male and 20 female patients. All patients underwent computed tomography or magnetic resonance imaging. The most common complications were postoperative epistaxis and swallowing difficulty. The treatment of maxillary antrum tumours is complicated and needs advancements to improve early presentation, timely diagnosis, and better management outcomes.

A retrospective cross-sectional analysis of swallowing and tongue functions in maxillectomy patients

“…Twenty patients had experienced radiotherapy and 14 patients had undergone partial soft palate resection. The number of remaining teeth was 15 [IQR: [9][10][11][12][13][14][15][16][17][18][19][20][21]. All of the patients could use their maxillofacial prostheses without any speci c problems such as poor retention and remarkable nasal leakage.…”

“…Several comparative studies have revealed that prosthetic intervention with maxillofacial prostheses or obturators [17,18], and surgical reconstruction with or without prostheses [13][14][15][16] had positive effects on swallowing function. On the other hand, the evidence for an association between swallowing function and several factors in maxillectomy patients including tongue functions with maxillofacial prostheses and cancer treatment-related factors has been lacking.…”

“…Swallowing is equally important for well-nutrition, whereas it must be an extremely complex neuromuscular process [11,12]. In maxillectomy patients, swallowing is often impaired by resection and radiotherapy [13][14][15][16] and previous studies evaluated the effect of maxillofacial prostheses on swallowing after maxillectomy [16][17][18][19][20][21][22], although functional impacts of maxillofacial prostheses remain controversial because multiple variables are related to swallowing. However, it is obvious that tongue functions play a crucial role in swallowing, especially during oral and pharyngeal phase [23][24][25][26].…”
