Voice rehabilitation with voice prosthesis: Long term results, complications and risk factors.

OBJECTIVES: Despite the advances in surgical and non-surgical organ preservation treatments, total laryngectomy (TL) remains the most effective treatment in advanced larynx cancer and as salvage procedure in chemoradiation failure. One of the most devastating sequel after TL is loss of voice. Voice prosthesis (VP) is currently the preferred choice for voice rehabilitation. The purpose of this study is to identify VP complications, its lifespan and factors that influence the longevity of the VP. METHODS: We performed a retrospective study at a Tertiary University Hospital. Medical records of patients that underwent total laryngectomy, between January 1st of 2008 and 31st of December of 2017 were analyzed. RESULTS: Of the 84 patients that underwent laryngectomy, 60 had VP. The average age at the time of surgery 60.2 years old and there was a male preponderance (57:3). The mean lifespan of the prosthesis was 7.53 months. Leakage through the prosthesis was the most common reason for replacement of the prosthesis, followed by leakage around the prosthesis. Follow up time and manual suture were associated with prosthesis replacement. There was no significant relationship between the staging, tumor location or adjuvant radiotherapy and number of prosthesis replacement or its lifespan. CONCLUSIONS: Rehabilitation after TL is of major importance to improve quality of life after surgery. Tracheoesophageal puncture with voice prosthesis is a safe procedure for vocal rehabilitation and was performed in the majority of patients in our study. Follow-up time and type of suture were the main determinants of the lifespan of the prosthesis.

Objetivos: A pesar de los avances en los tratamientos quirúrgicos y no quirúrgicos para la preservación de órganos, la laringectomía total (LT) sigue siendo el tratamiento más efectivo en el cáncer avanzado de laringe, y como procedimiento de rescate en caso de fallo de la radioquimioterapia.Una de las secuelas más devastadoras tras la LT es la pérdida de la voz. Las prótesis de voz (PV) son actualmente la elección preferida para la rehabilitación de la voz. El objetivo de este estudio es identificar las complicaciones de las PV, su vida útil y los factores que influyen en la longevidad de dichas prótesis.MétodosRealizamos un estudio retrospectivo en un hospital universitario terciario, en el que se analizaron los registros médicos de los pacientes sometidos a laringectomía total entre el 1 de enero de 2008 y el 31 de diciembre de 2017.ResultadosDe los 84 pacientes sometidos a laringectomía, 60 tenían PV. La edad media en el momento de la cirugía fue de 60,2 años, y hubo una preponderancia de varones (57:3).La vida útil media de las prótesis fue de 7,53 meses. La fuga a través de la prótesis fue el motivo más común de su sustitución, seguida de la fuga alrededor del dispositivo.El tiempo de seguimiento y la sutura manual estuvieron asociados a la sustitución de la prótesis. No existió una relación significativa entre la estadificación, la localización del tumor o la radioterapia adyuvante y el número de sustituciones de prótesis o su vida útil.ConclusionesLa rehabilitación tras la LT es de gran importancia para mejorar la calidad de vida tras la cirugía. La punción traqueoesofágica con prótesis de voz es un procedimiento seguro para la rehabilitación de la voz, habiéndose realizado en la mayoría de los pacientes de nuestro estudio.El tiempo de seguimiento y el tipo de sutura fueron los principales determinantes de la vida útil de las prótesis.

Voice parameters in children with Down syndrome.

Down syndrome (DS) is the most frequent chromosomal disorder. Commonly, individuals with DS have difficulties with speech and show an unusual quality in the voice. Their phenotypic characteristics include general hypotonia and maxillary hypoplasia with relative macroglossia, and these contribute to particular acoustic alterations. Subjective perceptual and acoustic assessments of the voice (Praat-4.1 software) were performed in 66 children with DS, 36 boys and 30 girls, aged 3 to 8 years. These data were compared with those of an age-matched group of children from the general population. Perceptual evaluations showed significant differences in the group of children with DS. The voice of children with DS presented a lower fundamental frequency (F(0)) with elevated dispersion. The conjunction of frequencies for formants (F(1) and F(2)) revealed a decreased distinction between the vowels, reflecting the loss of articulatory processing. The DS vocalic anatomical functional ratio represents the main distinctive parameter between the two groups studied, and it may be useful in conducting assessments.
