Acoustic analysis of cry in with cleft palate patients / Análisis acústico del llanto en pacientes con hendidura palatina

INTRODUCTION: Crying in newborns and infants is a functional expression of biological interest. Through, acoustic analysis of crying, results of a primary palatoplasty can be evaluated in patients with cleft palate before development of speech, is objective, non-invasive, quick and simple tool for vocal exploration. The objective is to determine Fundamental Frequency (F0) of spontaneous crying in patients with pre and postoperative cleft palate, and compare with healthy control group through PRAAT software, in period between 2017 and 2019. MATERIALS AND METHODS: A sample of 16 patients from 18 to 30 months of age with cleft palate was obtained. Recordings were made of spontaneous pre and postoperative crying, and healthy control group; later were digitally recorded, and analyzed through PRAAT Software. RESULTS: 56.2 % were female and 43.7 % were male, witn average age of 25.8 months. Primary palatoplasty was performed using Veau Wadrill technique and Furlow technique. F0 of crying was Pitch average value 349.125 Hz preoperative and Pitch average postoperative control 369.775 Hz. More acute crying emissions were observed in postoperative period (p < 0.000), presenting similar values with control group (p < 0.000). CONCLUSION: Fundamental frequency (F0) was determined in patients with cleft palate, they presented a significant increase of 15,5 % in postoperative controls of primary palatoplasty, similar to healthy control group

INTRODUCCIÓN: El llanto de los recién nacidos y lactantes es una expresión funcional de interés biológico, por lo cual, a través del análisis acústico del llanto se pueden evaluar los resultados de una palatoplastia primaria en pacientes con hendidura palatina antes del desarrollo del habla, por ser una herramienta objetiva, no invasiva, rápida y sencilla de exploración vocal. El objetivo es determinar la frecuencia fundamental (F0) del llanto espontáneo en los pacientes con hendidura palatina pre y posoperatorio, y comparar con el grupo control sano a través del software PRAAT, en el periodo entre el año 2017 y 2019. MATERIALES Y MÉTODOS: Se obtuvo una muestra de 16 pacientes de 18 a 30 meses de edad con hendidura palatina. Se realizaron grabaciones del llanto espontáneo pre y posoperatorio, y del grupo control sano; posteriormente fueron grabadas digitalmente, y analizadas a través del software PRAAT. RESULTADOS: El 56,2 % fue del género femenino y el 43,7 % del género masculino, con edad promedio de 25,8 meses. Se realizó palatoplastia primaria mediante técnica de Veau Wadrill y técnica Furlow. La F0 del llanto fue de valor promedio Pitch 349.125 Hz preoperatorio y un control posoperatorio promedio Pitch 369.775 Hz. Se evidenció emisiones del llanto más agudas en el posoperatorio (p < 0,000), presentando valores similares con el grupo control (p < 0,000). CONCLUSIÓN: Se determinó frecuencia fundamental (F0) en los pacientes con hendidura palatina, presentaron un incremento significativo de 15,5 % en los controles posoperatorio de palatoplastia primaria, similares al grupo control sano

Surgical ciliated cyst after maxillary orthognathic surgery: a literature review and case report.

PURPOSE: Surgical ciliated cyst of the maxilla is a rare complication following surgical procedures or trauma involving the maxillary sinus. The surgical ciliated cyst of the maxilla is a rare lesion and appears as a delayed complication after surgery in the maxillary sinus, midface osteotomies, traumatic tooth extraction and maxillary fractures. CASE REPORT AND LITERATURE REVIEW: We report a case that occurred 5 years after a maxillary sinus surgery in a Caucasian Female. A well-defined unilocular radiolucency in the right anterior maxilla was noted in cone beam image associated to osteosynthesis material. The lesion was completely excised, and upon histological examination, findings were consistent with Ciliated cyst. The PubMed database was searched for PMC within the last 15 years. RESULTS: Together with the current case, we found 18 reports including 21 patients describing PMC. It wasdiagnosed at a mean time of 22 years after causal surgery at a mean age of 47 years. The main radiologicalsign was a unilocular radiolucency. DISCUSSION: This lesion may present histologically different epithelial linings, but respiratory epithelium was the most frequent. The most important clinical and pathological features of these conditions are also discussed. CONCLUSION: Although surgical ciliated cysts have only rarely been reported after orthognathic surgery, anincreased awareness of this possibility is necessary to avoid delays in diagnosis.

Modified basal osteotomy combined with osteogenic distraction (Hemi-Wing distraction) for correction of facial asymmetry: A new technique.

Complete restoration of facial asymmetry is always difficult to achieve. Facial asymmetry due to growth disturbances of the jaws almost requires orthognathic surgical correction, followed, in many cases, by soft tissue corrections. Mandibular hypoplasia is the earliest skeletal manifestation of Hemifacial microsomy and the clinical defect becomes worse with the time, due to asymmetric growth and secondary midface deformity accompanying. Despite correction of the occlusal plane, facial asymmetry can persist if the mandibular body differs in height. We designed a new technique for skeletal correction of the mandibular basal plane combined with orthognatic surgery that avoided the disadvantages and limitations of other techniques. A 20-year-old male patient with facial asymmetry due to Hemifacial microsomy Type I also requires preoperative orthodontic treatment to align and level their teeth. He showed a 2mm midline shift to the left in combination with a cross bite of the left side. We decide to do a vertical enlargement of the mandibular left border by mandibular Hemiwing osteotomy and unilateral split ramus osteotomy for dental lines alignment with 8 mm of advancement of the hemi - wing genioplasty. Modificated basal osteotomy combined with osteogenic distraction works better than the classic total basal osteotomy with autologous bone graft, if used for the correct indications. We advocate this technique for its efficacy, simplicity, and safety. This technique can be apply for correction of vertical and transverse discrepancies of the mandibular border and combined with sagittal ramus osteotomies for correction of asymmetrical dental lines and oclusal plane.
