Nasal Septal Deviation: A Comprehensive Narrative Review.

The nasal septum is an osteocartilaginous wall that divides the nose into two nasal cavities. Asymptomatic minor deviation of the septum is considered a normal developmental variation found in the majority of the population. The reported global prevalence rates had great variation due to the extent of deviation considered in the reporting studies. Previous classification systems have been proposed to classify the nasal septal deviation according to the characteristics of the nasal septum seen horizontally and vertically. For some patients, the degree of the deviation may affect the nasal airflow causing obstruction or impairing the olfactory function. Headache, rhinosinusitis, high blood pressure, obstructive sleep apnea, and breathing sounds are also among the clinical presentations of nasal septal deviation. Clinical assessment is sufficient to make the diagnosis while imaging techniques are required for decision-making. Radiological imaging techniques such as computed tomography (CT) are used to classify and assess the severity of the deviated septum. Surgical correction is the treatment option for nasal septal deviation. Septoplasty is the most common procedure used for nasal correction with high satisfaction levels and low complication rates. In this review, we present a comprehensive summary of the concept, presentation, diagnosis, management options, and quality of life of patients with nasal septal deviation.

Lymphangioma: A Rare Benign Cystic Pancreatic Lesion.

Pancreatic lesions are more commonly identified nowadays with the widespread use of imaging investigations. Pancreatic lesions are heterogeneous groups of pathologies with different behavior and prognosis. It is quite difficult to differentiate these lesions because of the shared clinical manifestation and the overlapping imaging features of these lesions. We report the case of a 38-year-old woman who presented with a complaint of a 3-month history of epigastric abdominal pain radiating to her back. She reported a gradual increase in the severity of the pain. She described it as sharp in quality and was exacerbated with food intake and was alleviated by oral paracetamol. There was no history of abdominal distension, weight loss, or change in appetite. Apart from asthma, she had no other comorbid conditions or previous surgeries. She was referred to have an abdominal computed tomography scan which showed a large lesion that appears to arise from the head of the pancreas and was cystic with no soft tissue component. The radiological impression was a lymphoepithelial cyst, duplication cyst, pseudocyst from previous acute pancreatitis, lymphangioma, or intraductal papillary mucinous neoplasm. The decision for open surgical removal was decided. The patient underwent laparotomy and the cystic lesion was identified as arising from the pancreatic head. Complete resection of the mass was carried out with no complications. Histopathological examination revealed cystic lesions with the presence of lymphoid cells aggregates peripherally. The lining of the channels was positive for CD31 and was negative for CD34. Such findings conferred the diagnosis of lymphangioma. Lymphangioma is a very rare tumor of the pancreas with non-specific clinical and imaging features. Complete surgical resection of the lesion is the treatment of choice and the prognosis of the tumor is favorable if the tumor was resected completely.
