Abstract

Background: Osteomas are the most common benign tumors of the sinonasal region. Often asymptomatic, they are frequently discovered incidentally during imaging studies conducted for unrelated conditions. Osteomas typically range in size from 2 to 30 mm; those larger than 30 mm or weighing more than 110 g are classified as "big" or "giant" osteomas. Giant osteomas of the paranasal sinuses are extremely rare and can extend into the intraorbital or cerebral space, leading to significant complications. When osteomas become symptomatic, the standard treatment is surgical intervention to alleviate associated issues and prevent further progression.

Case presentation: This report discusses a case of a giant fronto-ethmoidal osteoma (45 × 42 mm) with intracranial and orbital extension, focusing on the clinical presentation, diagnostic process, and surgical management. We present the case of a 30-year-old Black female patient from Addis Ababa, Ethiopia, with a fronto-ethmoidal osteoma causing compression of the ocular globe and the left frontal lobe. Given the intracranial extension, a combined surgical team consisting of an ENT surgeon and a neurosurgeon was assembled to address the case. The surgery was performed via an external and lateral rhinotomy with a Lynch extension approach, aiming for complete resection of the osteoma originating from the frontal sinus and extending into the orbit and intracranial space.

Conclusion: Giant sinonasal osteomas are rare tumors. The primary goal of treatment is to completely remove the tumor using a combined endoscopic and external approach. Postoperative morbidity varies depending on the surgical technique used, and there is a risk of recurrence if the tumor is not entirely excised.

巨大额筛骨瘤(45 × 42 mm)伴颅内眶部扩张1例。
背景:骨瘤是鼻窦区最常见的良性肿瘤。通常无症状,它们经常在为不相关的疾病进行影像学检查时偶然发现。骨瘤的大小通常在2到30毫米之间;大于30毫米或重量超过110克的骨瘤被归类为“大”或“巨型”骨瘤。巨大的鼻窦骨瘤是极为罕见的,可扩展到眶内或大脑空间,导致严重的并发症。当骨瘤出现症状时,标准的治疗方法是手术干预以减轻相关问题并防止进一步进展。病例报告:本报告讨论一例巨大额筛骨瘤(45 × 42 mm)伴颅内及眼眶扩张,并着重于临床表现、诊断过程及手术处理。我们报告一名来自埃塞俄比亚亚的斯亚贝巴的30岁黑人女性患者,患有额筛骨瘤,导致眼球和左额叶受压。考虑到颅内延伸,一个由耳鼻喉外科医生和神经外科医生组成的联合手术小组被召集来处理这个病例。手术通过外外侧鼻切开术和Lynch延伸入路进行,目的是完全切除起源于额窦并延伸到眼眶和颅内间隙的骨瘤。结论:巨大鼻窦骨瘤是一种罕见的肿瘤。治疗的主要目标是使用内窥镜和外部联合入路完全切除肿瘤。术后发病率取决于所使用的手术技术,如果肿瘤未完全切除,则有复发的风险。

期刊介绍: JMCR is an open access, peer-reviewed online journal that will consider any original case report that expands the field of general medical knowledge. Reports should show one of the following: 1. Unreported or unusual side effects or adverse interactions involving medications 2. Unexpected or unusual presentations of a disease 3. New associations or variations in disease processes 4. Presentations, diagnoses and/or management of new and emerging diseases 5. An unexpected association between diseases or symptoms 6. An unexpected event in the course of observing or treating a patient 7. Findings that shed new light on the possible pathogenesis of a disease or an adverse effect
