Tumores de nariz y senos paranasales en pacientes pediátricos: experiencia de un hospital pediátrico de cuarto nivel en Bogotá, Colombia, 2013-2018 / Nasal and Paranasal Sinus Tumours in the Pediatric Population: Experience from a Pediatric Hospital in Bogotá, Colombia, 2013 ­ 2018

Introducción: los tumores en la cavidad nasal y los senos paranasales son un problema serio en la población pediátrica, principalmente por la inespecificidad de los síntomas que lleva a que pasen de meses a años antes de la sospecha de una patología neoplásica, con un impacto en la calidad de vida del paciente y su entorno. Al sospechar de la presencia de un tumor nasosinusal se requiere la realización de imágenes diagnósticas como la resonancia magnética y la tomografía computarizada de los senos paranasales. Cuando se tiene un diagnóstico etiológico, siempre se debe realizar un abordaje multidisciplinario. Materiales y métodos: realizamos un estudio retrospectivo de corte transversal de la cohorte de pacientes con tumores de nariz y senos paranasales atendidos en un hospital pediátrico de cuarto nivel en Bogotá, Colombia, entre 2013-2018. Resultados: se incluyeron un total de 54 pacientes con tumores malignos y benignos de nariz y senos paranasales, la mayoría fueron hombres con un promedio de edad de ocho años. Generalmente se presentaron con síntomas nasosinusales, el principal fue obstrucción nasal en el 80 % de los pacientes. El diagnóstico mas común fue craneofaringioma en un tercio de los pacientes, seguido por angiofibroma nasofaríngeo y linfoma de Burkitt. Conclusión: es importante conocer los síntomas y características clínicas de los pacientes pediátricos con tumores nasofaríngeos. Por esta razón, se considera importante presentar la casuística y características de los tumores de nariz y senos paranasales recogida durante 5 años, en un hospital pediátrico de cuarto nivel en la ciudad de Bogotá, Colombia

Introduction: Tumors in the nasal cavity and paranasal sinuses in children is a serious problem in the pediatric population, mainly due to the non-specificity of the symptoms that leads to years or months passing before the suspicion of a neoplastic pathology. With an important impact in quality of life not only in the patient but also in its family environment. When suspecting a sinonasal tumor, diagnostic images such as magnetic resonance and computed tomography of the paranasal sinuses are required. When you have an etiological diagnosis always do a multidisciplinary approach. Methods: We conducted a cross-sectional study of the cohort of patients that had been diagnose with tumors of the nasal cavity or paranasal sinuses in a fourth level pediatric hospital in Bogota, Colombia between 2013 - 2018. Results: 54 patients were included, the majority of them were men, with an average age of eight years. They mainly presented with nasal symptoms, the main one being nasal obstruction in 80% of patients. The most common diagnosis was cranipharyngioma in one third of the patients, followed by nasopharyngeal angiofibroma and Burkitt lymphoma. Conclusion: We present this article with the objective of presenting the tumors of nose and paranasal sinuses casuistry collected during 5 years in a fourth level pediatric hospital in the city of Bogotá and the imaging characteristics for the diagnosis of these are reviewed with some clinical cases as examples.

A Case of Schwannoma Originated from the Posterior Nasal Septum / 대한이비인후과학회지

Schwannomas are slow-growing, benign neurogenic tumors arising from the sheath of myelinated nerve fibers. They usually occur in the head and neck region. Only 4% of schwannomas found in the head and neck region originate in the sinonasal tract. Schwannoma of the nasal septum is rarer, and only few cases have been previously reported in the literature. We experienced a rare case of the schwannoma of the posterior nasal septum in a 71-year-old woman. She was treated successfully by transnasal endoscopic surgery. No recurrence was detected within 18 months follow-up period.

Cranially-based nasolabial flaps for the reconstruction of nasal surgical defects

BACKGROUND: Cranially-based nasolabial flaps are a good alternative for the reconstruction of nasal defects. METHODS: A cranially-based nasolabial flap was used in 18 patients to reconstruct defects of the nose from 2010 to 2016, and the long-term results are presented in this report. RESULTS: Fifteen of the flaps completely survived. All the patients had a bulky appearance, but they did not want to undergo a second operation for cosmesis. The dissection of the flap took approximately 20 minutes, and the total operation lasted for 1 hour. The patients were hospitalized for 1–7 days, and the postoperative follow-up period was 1–28 months (mean, 17 months). CONCLUSIONS: The cranially-based nasolabial flap possesses all the advantages of the traditional forehead flap, and can safely be used in selected cases.

A Case of Chondro-Osseous Respiratory Epithelial Adenomatoid Hamartoma Originated from Nasal Cavity

Hamartoma is a non-malignant malformation or developmental anomaly of tissue development that may occur anywhere in the body but is rarely reported in the nasal cavity, paranasal sinuses, or nasopharynx. Chondro-osseous respiratory epithelial adenomatoid hamartoma (CO-REAH) of the nasal cavity is exceedingly rare, and can be confused both grossly and microscopically with more serious sinonasal tumors. We present the case of a 58-year-old man with a nasal cavity mass, which was removed by an endonasal approach. Radiographic and histological studies permitted a diagnosis of CO-REAH in this case.

A Case of Fibro-Osseous Hamartoma Originated from Nasal Cavity / 대한이비인후과학회지

Hamartoma occurs in all areas of the body, especially in the liver, spleen, kidney and lung. However, it was rarely reported in the nasal cavity, paranasal sinuses, or nasopharynx. The histopathological and clinical differential diagnosis of fibro-osseous hamartoma of the sinonasal tract includes ossifying fibroma, fibrous dysplasia and osteoma. We present the case of a 57-year-old man with nasal obstruction in right side, which was treated with complete resection by endoscopic approach. A combination of clinical, radiographic and histological information permitted a diagnosis of a benign fibro-osseous hamartoma in this case.

Nasal Chondromesenchymal Hamartoma: A Case Report

We report a case of nasal chondromesenchymal hamartoma. A 14-year-old boy presented with a 5 cm sized mass in the left maxillary sinus, facial swelling and a loose tooth. A subtotal left maxillectomy with a bone graft was performed. The excised mass was composed of partly encapsulated, solid and cystic fragments of soft tissues. The mass contained chondroid and myxoid areas consisting of mesenchymal tissues including hyaline cartilage, osteoid and spindle cells in various proportions. The hyaline cartilage component was the most prominent. The spindle cell component had a fibrous matrix with variable myxoid or sclerotic changes. Thick hyalinized eosinophilic osteoid-like trabeculae were focally present. Immunohistochemically, all the mesenchymal cells tested positive for vimentin. The chondrocytes tested positive for the S-100 protein, and the spindle cell component showed focal immunoreactivity for smooth muscle actin and desmin. However, the cells were negative to pan-cytokeratin and p63.

Reconstruction of Nasal Defects with Local Flap: Analysis of 7 Cases / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Reconstruction of the nasal defect caused by resection of nose neoplasm or trauma represents a particular challenge to reconstructive surgeons. Each tissue defect has to be evaluated individually in terms of the best possible substitution or alteration from both aesthetic and functional points of view. The method of reconstruction varies according to the location, size, and depth of the defect. Of various methods, local Rap is frequently used because the nasal contours are variable with convex and concave surfaces in close proximity, and there is little lax skin from which to borrow tissue for closure, and the skin of the nose has a texture and color not easily matched by skin elsewhere. Of various local flaps, transposition flap and forehead flap are most frequently used for reconstruction of the nasal defect. The authors carried out retrospectively a clinical study on seven cases of nasal reconstruction that used local flaps after resection of malignant tumors of the nose with a brief review of the literature. MATERIALS AND METHODS: A single surgeon's results in seven consecutive patients were clinically analyzed retrospectively. RESULTS: There were no significant complications. Good aesthetic and functional outcomes were observed with nasal defects reconstructed with the local flaps. CONCLUSION: Local flaps were the most useful choice for reconstructive rhinoplasty. Transposition flaps and forehead flaps, in particular, were particularly useful for each cosmetic unit of the nose.
