The Profile of Sinonasal Tumors with Orbital Involvement in Dr. M. Djamil General Hospital, Padang, Indonesia: A 10-Year Overview

Background: Sinonasal tumors are rare tumors, either malignant or benign, that vary greatly based on the origin and primary tumor location in the sinonasal tract. The close anatomical relationship between the sinonasal tract and the orbital cavity makes orbital involvement very common (50%-80%) in sinonasal tumors, and this indicates a negative prognostic factor in sinonasal malignancy. The purpose of this study is to demonstrate the profile of sinonasal tumors with orbital involvement in our center.
 Methods: Retrospective study from oncology subdivision files and medical records from January 2011 – December 2020. Collected data including age, gender, the clinical manifestations of orbital involvement, primary location, histopathology, and management of sinonasal tumors.
 Results: There were 35 patients examined by the oncology subdivision either directly came or consulted from the ENT department, consisting of 18 (51.4%) males and 17 (48.6%) females. The age of patients ranged from 11 to 83 years old. with the most common age groups being 41-50 and 51-60 (25.7% in each age group). The majority of the patients (77.1%) had presented with proptosis. Maxillary sinus was the most common (45.7%) primary site of tumors, and squamous cell carcinoma was the most common (51.4%) histopathology found. Most of the patients (37.1%) were treated with a combination of chemotherapy and radiotherapy.
 Conclusion: Orbital involvement commonly occurs in malignant sinonasal tumors with proptosis as a major clinical presentation. A combination of chemotherapy and radiotherapy was the most common practice management because the tumors were unresectable at the time of presentation.

Imaging Recommendations for Diagnosis, Staging, and Management of Sinonasal Tumors

AbstractSinonasal tumors are a relatively rare and heterogeneous group of tumors. Owing to their nonspecific presentation and rarity, they can be potentially overlooked resulting in delayed diagnosis and management, and increased patient morbidity. Imaging is crucial for the detection, staging, surgical planning, follow-up as well as surveillance of sinonasal masses, wherein computed tomography (CT) and magnetic resonance imaging (MRI) play complementary roles. CT is better at depicting bony changes, while MRI is useful for delineating the extent of soft tissue lesion, detect perineural, intracranial, or intraorbital spread as well as differentiate trapped sinus secretions from tumor tissue. Other modalities like fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) and arteriography can be selectively employed. FDG-PET is useful for metastatic workup and detection of residual/ recurrent disease. Arteriography and endovascular image-guided interventions are useful to delineate supply of vascular tumors and perform preoperative embolization. A systematic evidence-based approach to a possible case of sinonasal tumor can go a long way in streamlining the detection and management of these tumors, while optimizing the use of available healthcare resources.

Maxillectomy: Indications and outcome at a tertiary hospital in Nigeria – A review of 113 cases

Background: Maxillectomy is the surgical procedure often indicated for the management of tumours and some non-neoplastic conditions arising from or involving the maxilla. This procedure is associated with significant functional and aesthetic deficits with concomitant psychological effect. The aim of this study is to evaluate maxillectomies carried out in our facility over a 16-year period. Patients and Methods: This is a retrospective study of cases of maxillectomy carried out in the Departments of Oral and Maxillofacial Surgery and the Ear, Nose and Throat (ENT) of our hospital from 2000–2016. The clinical data retrieved from the records of patients included age, gender, presentation, site of lesion, surgical intervention and rehabilitation options. Results: A total of 113 maxillectomies were performed in 52 males and 61 females. The age range was 13–82 years with a mean age of 37.4 ± 16.1 years. Majority of participants are of a low-socioeconomic status. The mean duration of symptoms before presentation was 12.4 months. Malignant lesion (59/113) accounted for the majority of cases seen. Total maxillectomy was the most frequent procedure (53.1%). Recurrence was seen in 20.4% of all cases. Major limitations to therapeutic intervention were lack of fund and late presentation. Conclusion: Delay in presentation and lack of fund remains the main challenges in the management of sinonasal tumours. Management of the maxillectomy defect remains largely limited to rehabilitation with an obturator in our environment.

Management of Sinonasal Tumors: Prognostic Factors and Outcomes: A 10 Year Experience at a Tertiary Care Hospital

Sinonasal malignancies are said to be a highly heterogeneous group of cancers, accounting for less than 1% of all cancers and less than 3% of all upper aerodigestive tract tumors. Originating from any histologic components of the sinonasal cavity, the histopathology of these tumors is diverse. Accordingly, treatment options vary, surgery being the mainstay in most of them. Recurrence rates differs with each histological type of tumor, dependent on various factors. In this article, we have tried to identify the prevalent characteristics of sinonasal malignancies and to outline the prognostic factors affecting the outcome. It is a retrospective study design with a total number of 102 patients. Patients diagnosed with sinonasal malignancies were included and any patient previously operated outside our institute or having received prior radiation or chemotherapy were excluded. The patients were selected over a period of 10years, from 2000 to 2010. Data was analyzed using SPSS 17. Majority of the sinonasal tumors were squamous cell carcinomas involving the maxillary sinus. Locoregional recurrence was found to be more frequent in patients with positive neck nodes on final histopathology. Sinonasal malignancies are mostly squamous cell in variety and recurrence of these rare entities is dependent on the histological variety and the presence of positive neck nodes.

Endoscopic Medial Maxillectomy Breaking New Frontiers

Endoscopy has changed the perspective of rhinologist towards the nose. It has revolutionised the surgical management of sinonasal disorders. Sinus surgeries were the first to get the benefit of endoscope. Gradually the domain of endoscopic surgery extended to the management of sino nasal tumours. Traditionally medial maxillectomy was performed through lateral rhinotomy or mid facial degloving approach. Endoscopic medial maxillectomy has been advocated by a number of authors in the management of benign sino-nasal tumours. We present our experience of endoscopic medial maxillectomy in the management of sinonasal pathologies.
