ABSTRACT
Resumen La insuficiencia velofaríngea (IVF) es una de las principales secuelas estructurales tras la palatoplastía primaria en casos de fisura de paladar. La IVF se caracteriza por la ausencia de tejido suficiente para lograr un cierre adecuado del mecanismo velofaríngeo durante el habla, lo que conlleva a una resonancia hipernasal y la emisión nasal de aire durante la producción de sonidos orales. Al respecto, el tratamiento ideal para corregir la IVF es quirúrgico, dentro de los cuales el colgajo faríngeo de pedículo superior es uno de los procedimientos más utilizados en nuestro país. Para su realización es fundamental determinar el ancho necesario, lo cual puede ser determinado mediante una videofluoroscopía multiplano (VFMP). Por esto, con el objetivo de potenciar el trabajo multidisciplinario en la corrección quirúrgica de la IVF, a continuación, se presentan los procedimientos de evaluación fonoaudiológica, videonasofaríngoscopía flexible y videofluoroscopía multiplano utilizados para la planificación quirúrgica de un colgajo faríngeo en un adolescente chileno diagnosticado con IVF secundaria a fisura palatina operada. Además, se describe el uso de la VFMP en la planificación quirúrgica del colgajo faríngeo mediante una revisión de literatura.
Abstract Velopharyngeal insufficiency (VPI) is one of the main structural sequelae after primary palatoplasty in cases of cleft palate. VPI is characterized by the absence of sufficient tissue to achieve adequate closure of the velopharyngeal mechanism (VFM) generating hyper-nasal resonance and nasal emission during the production of oral sounds. In cases of cleft palate, the ideal treatment to correct VPI is surgery. The upper pedicle pharyngeal flap is one of the most widely used procedures. To plan it, is essential to determine the appropriate width, which can be determined by means of multiplane videofluoroscopy (MPVF). For this reason, and with the aim of promoting multidisciplinary approach in the surgical correction of VPI, the following procedures such as speech and language evaluation, flexible videonasopharyngoscopy and multiplane videofluoroscopy used for the surgical planning of a pharyngeal flap, in a Chilean adolescent diagnosed with VPI secondary to operated cleft palate, will be presented. In addition, the use of MPVF in pharyngeal flap surgical planning is described through a literature review.

OBJECTIVES@#This study aims to investigate the incidence and severity of obstructive sleep apnea (OSA) in cleft patients with velopharyngeal insufficiency (VPI) after pharyngeal flap surgery (PFS) and explore the influence of operation age.@*METHODS@#A retrospective study was conducted in 82 cleft patients after PFS. The patients were divided into two groups according to their age at the time of surgery. The incidence and severity of OSA were assessed at least 1.2 years (mean 6.0 years) postoperatively by polysomnography (PSG).@*RESULTS@#The incidence rates of OSA were 20% in the adult group and 31% in the child group. No significant difference was found between the two groups (@*CONCLUSIONS@#Some patients still have OSA average of 6.0 years after PFS, and operation ageis unrelated to the incidence and severity of OSA.

RESUMEN La estenosis faríngea es una complicación muy poco frecuente de la adenoamigdalectomía. Consiste en un estrechamiento de la vía aerodigestiva superior secundaria a la adhesión parcial o total de las estructuras que componen la orofaringe producto de una disección extensa al realizar amigdalectomía. El objetivo de este trabajo es presentar tres casos clínicos tratamiento y correspondiente técnica quirúrgica. Se describen tres pacientes operados durante la edad preescolar de adenoamigdalectomía, que cursaron en el posoperatorio con estenosis faríngea. Todos presentaron roncopatía severa, respiración oral y resonancia hiponasal. La nasofibroscopía evidenció estrechez faríngea en distintos grados. A todos se les realizó resección del tejido cicatricial y faringoplastía con colgajo miomucoso y posterior rehabilitación con bulbo faríngeo. El uso de colgajos faríngeos posterior a la liberación de adherencias posadenoamigdalectomía permite aportar tejido sano a zonas cruentas, evitando la formación de nuevas adherencias y restituyendo la permeabilidad oronasal. El bulbo faríngeo es fundamental para mantener un apropiado lumen y manejo de la cicatrización en el posoperatorio. La técnica de colgajo faríngeo lateral, que interpone mucosa faríngea sana para la cobertura del lecho cruento, constituye una alternativa quirúrgica eficaz para resolver la estenosis faríngea posquirúrgica.
ABSTRACT Pharyngeal stenosis is a very rare complication of adenotonsillectomy. It is caused by a narrowing of the upper aerodigestive pathway secondary to the total or partial adhesion of the retropharyngeal structures as a result of extensive dissection during tonsillectomy. Our aim is to present three consecutive clinical cases of pharyngeal stenosis after adenotonsillectomy, discuss its treatment and corresponding surgical technique. We present three infants with adenotonsillectomy with postoperative pharyngeal stenosis. All had severe snoring, oral breathing and hyponasal resonance. The nasofibroscopy showed pharyngeal obliteration in several degrees. All patients underwent scar tissue resection and pharyngoplasty with myomucosal flap and subsequent use of pharyngeal bulb. The use of pharyngeal flaps after release of pharyngeal adhesions allows to provide healthy tissue to row areas, avoiding new postoperative adhesions and providing adequate oronasal permeability. The pharyngeal bulb is essential to maintain permeability and management of scarring in the postoperative period. The technique of lateral pharyngeal flap, which aims to interpose healthy pharyngeal mucosa to cover the bloody bed, is an effective therapeutic alternative to solve post-surgical pharyngeal stenosis.

BACKGROUND: Velopharyngeal insufficiency that accompanies speech resonance and articulation disorders can be managed through several intervention methods such as speech-language therapy, prosthetic aids, and surgery. However, for patients with severe hypernasality, surgical interventions are highly recommended. Among available surgical techniques, the posterior pharyngeal flap is most common. CASE PRESENTATION: Two adult males with high nasalance scores underwent superiorly based posterior pharyngeal flap surgery, followed by speech testing by an expert speech-language therapist. Nasalance scores and articulation accuracy were assessed up until 1 year after the surgery. Nasalance scores were measured five times using a nasometer, after which the average value was calculated. CONCLUSIONS: Consistent declines in hypernasality over time are not easy to explain since the pedicled pharyngeal flap narrowed over time, secondary to cicatrization. However, scar tethering of the soft palate in a posterior direction could reduce the velopharyngeal port size over time. Therefore, long-term follow-up with intensive speech therapy is suggested for patients with severe hypernasality.

PURPOSE: Kabuki syndrome is a multiple malformation syndrome that was first reported in Japan. It is characterized by distinctive Kabuki-like facial features, skeletal anomalies, dermatoglyphic abnormalities, short stature, and mental retardation. We report two cases of Kabuki syndrome with the surgical intervention and speech evaluation. METHODS: Both patients had velopharyngeal insufficiency and had a superior based pharyngeal flap operation. The preoperative and postoperative speech evaluations were performed by a speech language pathologist. RESULTS: In case 1, hypernasality was reduced in spontaneous speech, and the nasalance scores in syllable repetitions were reduced to be within normal ranges. In case 2, hypernasality in spontaneous speech was reduced from severe level to moderate level and the nasalance scores in syllable repetitions were also reduced to be within normal ranges. CONCLUSION: The goal of this article is to raise awareness among plastic surgeons who may encounter such patients with unique facial features. This study shows that pharyngeal flap operation can successfully correct the velopharyngeal insufficiency in Kabuki syndrome and post operative speech therapy plays a role in reinforcing surgical result.

PURPOSE: The pharyngeal flap is one of the popular surgical methods to treat the problem of velopharyngeal dysfunction. This study evaluated speech outcome of patients who underwent superiorly based pharyngeal flap surgery based on timing of surgery. METHODS: A restrospective review of 50 patients who underwent pharyngeal flap surgery for velopharyngeal insufficiency from September 1996 to January 2008 was undertaken. Thirty patients with an available preoprative and postoperative speech assessments with at least 6 months of follow-up were included in this study. We checked out the significance of speech improvement after surgery analysing preoperative and postoperative scoring of speech assessment. We also investigated the direct relationship between the age at surgery and the degree of speech improvement, and the improvement score in different age groups. RESULTS: The mean score of preoperative speech was 52.6 +/- 7.4 points and postoperative speech was 58.6 +/- 6.5 points, which presented significant postoperative speech improvement with an average of 5.9 points (p<0.01). There was a significant inverse relationship between the age at operation and speech improvement degree (p<0.01, r=-0.54). Comparing the age groups, the age group of 4 to 5 years presented statistically significant speech improvement (p<0.01). CONCLUSION: we propose that all patients indicated should take pharyngeal flap irrespective of age. In this study, the younger the age at surgery, the higher degree of speech improvement, for which we suggest that surgical approach should be undertaken as early as possible, especially younger than 5 years of age.

ABSTRACT
The purpose of this study was to determine the efficacy of the CO2-laser energy in the operation of cleft palate and pharyngeal fiap compared with the traditional scalpel surgery. This investigation involved a series of 34 patients who underwent CO2-laser assisted palatoplasty and pharyngeal flap between 1995 and 1997. The 19 males and 15 females ranged from 13 months to 36 years in age (mean age of 5.6 years) at the time of surgery. The postoperative clinical follow-up ranged from 6 to 24 months (mean 12 months). The CO??-laser provided the surgeon with bloodless operative field with reduction in blood loss giving greater visibility. It also offered an advantage in deep surgical cavity in Ro-pharynx through an operative arm, reaching areas that would otherwise have been difficult to access by traditional means. There was less bleeding during the surgery using, and therefore, complication. associated with bleeding was minimalized. There were no significant differences in their wound healing between the traditional scapel method and the laser method. The mean hospitalization in the group using the laser was approximately one day less than the group using the scapel. Preliminary findings suggest that the laser assisted palatoplasty and pharyngeal flap has a definitive advantage in providing the surgeon with bloodless operative field, reduction of blood loss, early recovery. Disadvantages of the laser surgery is a learning curve, the expenses of equipment, and safety precaution.
