Endonasal endoscopic scalpel-forceps dacryocystorhinostomy vs endocanalicular diode laser dacryocystorhinostomy.

Purpose. To compare the efficacy of endonasal endoscopic dacryocystorhinostomy and endocanalicular diode laser dacryocystorhinostomy. Materials and methods. A total of 126 dacryocystorhinostomies were performed in 111 patients with epiphora. In 55% of cases (69/126) we performed an endonasal endoscopic dacryocystorhinostomy and in 45% (57/126) we carried out an endocanalicular dacryocystorhinostomy using diode laser. The mean age at diagnosis was 63 years. The mean age was higher in the endocanalicular group than in the endonasal endoscopic group: 64 versus 62 years. There were 25 men (23%) and 86 women (77%). Results. Successful results were achieved in 73% of patients (92/126). In the endonasal endoscopic group, 83% of patients (57/69) were symptom free compared to 62% of patients (35/57) in the laser diode group. A bicanalicular nasal silicone tube was left in place for a mean of 2.32 months in the endoscopic endonasal group and for 2.82 months in the laser diode group (p=0.164). Median time of recurrence after removal of the tube was 3.56 months (range 0-9.6): 2.84 months in the laser diode group and 4.87 months in the endonasal endoscopic group (p=0.069). Conclusions. The endonasal endoscopic approach achieved better results for nasolacrimal obstruction than the endocanalicular laser diode technique.

[Unilateral benign choanal polyp: review of 51 patients]. / Pólipo coanal unilateral benigno: revisión de 51 pacientes.

INTRODUCTION: Choanal polyps are a benign pathology arising in the sinusal mucosa and entering the nasal fossa heading for the choana. It is a unilateral condition mainly affecting young people. It must be surgically removed, with exeresis of both the nasal and the sinusal lesions. MATERIAL AND METHOD: A retrospective review has been made of 51 patients treated for choanal polyp at our centre. They were diagnosed through physical examination, nasal endoscopy, nasosinusal CT, and histological examination of biopsy from the mass in selected cases. RESULTS: The choanal polyps originated in the maxillary sinus in 46 cases, in the ethmoidal sinus of 5 patients, and only 1 in the sphenoid sinus. Antrochoanal and ethmoidochoanal polyps were simultaneously found in 1 patient. Unilateral nasal obstruction was the main clinical presentation in our series. Nasal discharge, epistaxis, and snoring were other initial clinical findings. Eighty-five per cent (39/46) of antrochoanal polyps (ACP) emerged into the nasal fossa through Giraldés's accessory orifice, and 15% (7/46) through the natural ostium of the sinus. The origin in the maxillary sinus was adequately documented in 18 cases. The endoscopic approach was used in 46 patients. Other options employed were the Caldwell-Luc approach and a combination of limited antrostomy and endoscopic nasal surgery; these were among the first cases seen and therefore the oldest. Two of them relapsed and were treated again with an endoscopic nasosinusal approach. CONCLUSIONS: Endoscopic nasosinusal surgery is a safe and effective option and represents the approach of choice for the treatment of this pathology.

Pólipo coanal unilateral benigno: revisión de 51 pacientes / Unilateral benign choanal polyp: review of 51 patients

Introducción: El pólipo coanal es una lesión benigna que nace en la mucosa sinusal y se desplaza hacia la fosa nasal en dirección a la coana. Es una enfermedad unilateral que afecta principalmente a pacientes jóvenes. Su tratamiento es quirúrgico, y se debe extirpar tanto la lesión endonasal como la endosinusal. Material y método: Se realizó una revisión de 51 pacientes afectados de pólipo coanal tratados en nuestro centro. Su diagnóstico se llevó a cabo mediante exploración clínica, endoscopia nasal, tomografía computarizada nasosinusal y, eventualmente, un estudio histológico de la masa polipoide. Resultados: La localización lesional endosinusal fue en 46 casos maxilar; en 5 casos, etmoidal, y un caso, esfenoidal. Un paciente presentó 2 pólipos coanales de forma simultánea, uno de tipo antrocoanal y otro etmoidocoanal. En la serie el síntoma principal de consulta fue la obstrucción nasal unilateral. Otros síntomas de presentación fueron rinorrea, epistaxis y roncopatía. El 85 % (39/46) de los pólipos antrocoanales emergían a la fosa nasal por un orificio accesorio de Giraldés, mientras que el 15 % (7/46), por el ostium natural del seno. La zona de implantación en el seno maxilar se documentó adecuadamente en 18 pacientes. El tratamiento quirúrgico utilizado fue la cirugía endoscópica nasosinusal en 46 casos. Otras opciones empleadas fueron el abordaje tipo Caldwell-Luc y la vía combinada antral y endonasal bajo control endoscópico, que se corresponden a los primeros casos tratados y, por tanto, a los más antiguos. Se apreciaron dos recidivas que fueron tratadas con éxito con cirugía endoscópica nasosinusal. Conclusiones: El abordaje por cirugía endoscópica nasosinusal es una opción segura y eficaz; constituye la maniobra de elección en su tratamiento (AU)
