ABSTRACT
Introducción: Las metástasis a distancia de tumores primarios a cuerdas vocales son poco frecuentes. Las metástasis a laringe con mayor frecuencia corresponden a melanomas y carcinomas, afectando principalmente a la región supraglótica. Las metástasis a cabeza y cuello de los carcinomas de células renales (CCR) tienen una incidencia de 14-16%. Se presenta el caso de un paciente con metástasis de carcinoma de células claras renal a cuerdas vocales, cuya importancia recae en que es un caso poco frecuente y no existen reportes similares en el país. Paciente masculino, 57 años, con disfonía de 3 meses de evolución. Nasofibroscopía evidencia lesión polipoídea en cuerda vocal y ventrículo izquierdo. Se realiza microcirugía laríngea, enviando muestra a biopsia diferida, resultando lesión metastásica de CCR células claras. Evaluado por nefrología, se pesquisa tumor renal izquierdo sugerente de CCR. Las metástasis de neoplasias remotas a laringe son infrecuentes. Se considera al CCR el tercero en frecuencia respecto a neoplasias infraclaviculares. Éstas se pueden presentar hasta 10 años después del tratamiento del primario. Se recomienda seguimiento a largo plazo y énfasis a nuevos síntomas en región de cabeza y cuello, teniendo en consideración antecedente de CCR en pacientes con disfonía y lesiones polipoídeas en cuerdas vocales.
Introduction: The metastasis of distant site primary tumors to the vocal cords is infrequent. The most frequent source of metastasis to the larynx is melanomas and carcinomas, mainly affecting the supraglottic region. The metastasis to the head and neck of renal cell carcinomas (RCC) has an incidence of 14-16%. To present a case of metastasis of clear renal cell carcinoma to the vocal cords, since it is very infrequent, and there are no similar reports in the country. A male patient, 57 years old, presenting dysphonia for a duration of 3 months. Nasofibroscopy showed a polypoid lesion in the left vocal cord and ventricle. Larynx microsurgery was performed, and a sample was sent for biopsy, which reported a metastatic lesion of RCC clear cells. When assessed by nephrology, a left renal tumor is found, suggesting RCC. The metastasis of distant site neoplasias are infrequent. RCC is considered the third in frequency concerning to infraclavicular neoplasias. These can present up to 10 years after the treatment of the primary. Long term follow-up is recommended, and an emphasis on new symptoms in the head and neck region, considering the history of RCC in patients with dysphonia and polypoid lesions in vocal cords.

Objective:To explore the characteristics of vocal cord polyps and to study the application value of high-frequency ultrasound in the diagnosis of vocal cord polyps.Methods:A total of 169 patients diagnosed with vocal cord polyps ( 176 polyps in total ) by pathology in the Second Affiliated Hospital of Xi′an Jiaotong University from December 2016 to September 2021 were collected, the ultrasonic image characteristics of vocal cord polyps were summarized, and the characteristics of thyroid cartilage calcification at glottic level and the influence of the calcification range of thyroid cartilage at glottic level on the display of vocal cord polyps were observed.Results:The sonogram images of all vocal cord polyps showed the localized uniform low echo between the upper cortex and the ligament layer, the morphology could be circular and flat, and all polyps could be divided into high tension type and low tension type, no blood flow signal was found in 96.8% of the polyps. Round polyps were more easier to be detected by ultrasound than flat polyps, but there was no significant difference( P>0.05). The incidence of thyroid cartilage calcification at glottis level was higher in men than in women, and the difference was statistically significant( P<0.05). The range of thyroid cartilage calcification at the glottic level affects the display rate of vocal cord polyps.With the increase of calcification range, the display rate of vocal cord polyps gradually decreased. There was significant difference in the display rate of vocal cord polyps between non calcification group and moderate calcification group, non calcification group and severe calcification group(all P<0.05). Conclusions:Vocal cord polyps have typical sonographic appearance. High-frequency ultrasound can identify the morphology, location and size of vocal cord polyps. Especially for patients with no or mild calcification of thyroid cartilage at glottic level, ultrasound can meet the requirements of accurate diagnosis. It is expected to become an effective supplement to laryngoscopy, and apply for to the preliminary screening of vocal cord polyps and postoperative review.
ABSTRACT
Objective:To explore the effect of vocal training based on International Classification of Functioning, Disability and Health (ICF) and International Classification of Health Interventions (ICHI) on vocal function after vocal cord polyps. Methods:A framework of rehabilitation was developed with joint use of ICF and ICHI. From January, 2017 to December, 2018, 30 patients with vocal cord polyps and vocal dysfunction post operation were sampled. They accepted the therapy for a month, and assessed with Grade, Roughness, Breathiness, Asthenia and Strain scale (GRBAS), and measured acoustic parameters before and after operation, and after training, respectively. Results:The scores of GRBAS decreased after training, compared with those both before and after operation (F > 6.214, P < 0.05), as well as the acoustic parameters of fundamental frequency, fundamental frequency perturbation, normalized noise energy and amplitude perturbation (F > 9.655, P < 0.05). Conclusion:Vocal training based on ICF and ICHI is effective on vocal function after operation for vocal cord polyps.
ABSTRACT
OBJECTIVES@#To evaluate the therapeutic effect on the voice recovery of patients with vocal cord polyps undergoing the microsurgery of preoperative voice therapy.@*METHODS@#Twenty-six patients diagnosed with unilateral vocal cord polyp under stroboscope, who needed to undergo vocal cord loss resection under supportive laryngoscope, were randomly divided into control group (non-voice training) and treatment group (voice training), with each group of 13 patients. Patients in control group were just treated with surgical operation. Apart from surgical treatment, patients in treatment group received 6 hours intensive vocal therapy one week before the surgery. The therapy courses consist of the propaganda and education of voice care, postoperative vocal instruction and the patients' self-training under the guidance of voice therapists. The acoustic parameters (irregularity, breathiness, grade, jitter and shimmer) of the same patient were collected 24 to 48 hours before the surgery and 14 days after the surgery with Ling WAVES. The results were analyzed with SPSS 19.0.@*RESULTS@#The differences of all the five preoperative voice parameters between control group and treatment group are not significant; but postoperative breathiness and jitter in treatment group were significantly lower than that in control group, while the differences of irregularity, overall severity and shimmer were not significant between control group and treatment group. In control group, breathiness and jitter were significantly improved after surgery, while the differences of irregularity, breathiness and shimmer were not significant between preoperation and postoperation. In treatment group, all the five voice parameters were significantly improved after surgery. According to the laryngostroboscopic examination, the vocal fold polyps were excised completely in both groups.@*CONCLUSIONS@#Preoperative voice therapy contributes to the recovery of voice quality of the patients with vocal cord polyps. Combined intervention of surgery and voice therapy is an effective method to treat the patients with vocal cord polyps.

Esta investigación tiene por propósito describir las indicaciones terapéuticas, prescritas por médicos otorrinolaringólogos a pacientes diagnosticados con pólipo cordal. Se describen las etapas de evaluación, reposo vocal e indicaciones terapéuticas. El estudio intenta develar la presencia de una sistematización en el proceso anterior. Dicha información es recabada a partir de una encuesta vía mail aplicada a 29 médicos pertenecientes a la Sociedad Chilena de Otorrinolaringología (N=205). Los datos obtenidos permiten concluir que no existe un estándar en las indicaciones que se preguntan en la encuesta. Sin embargo, el total de médicos consultados manifiesta que sería útil la elaboración de protocolos para la evaluación y tratamiento de los pacientes con alteración vocal.
