Objective: Velopharyngeal insufficiency (VPI) can be caused by a variety of disorders. The most common cause of VPI is the association with cleft palate. The aim of this study was to evaluate the effectiveness of different surgical techniques for cleft palate patients with VPI: (1) velopharyngoplasty with an inferiorly based posterior pharyngeal flap (VPP posterior, Schönborn-Rosenthal), and (2) combination of VPP posterior and push-back operation (Dorrance).
Patients And Methods: 41 subjects (26 females, 15 males) with VPI were analysed. Hypernasality was judged subjectively and nasalance data were assessed objectively using the NasalView system preoperative and 6 months postoperative.
Results: Subjective analysis showed improved speech results regarding hypernasality for all OP-techniques with good results for VPP posterior and VPP posterior combined with push-back with success rates of 94.4% and 87.7%, respectively. Objective analysis showed a statistically significant reduction of nasalance for both VPP posterior and VPP posterior combined with push-back (p < 0.01). However, there were no statistically significant differences concerning measured nasalance values postoperatively between the VPP posterior and VPP posterior combined with push-back.
Conclusion: Based on our findings, both VPP posterior and VPP posterior combined with push-back showed good results in correction of hypernasality in cleft patients with velopharyngeal insufficiency.

Science is starting to unravel the neural basis of romantic love. The goal of this literature review was to identify and interpret the electrophysiological correlates of romantic love. Electroencephalography (EEG) and event-related potential (ERP) studies with a design that elicits romantic love feelings were included.

Purpose: To assess the efficacy of posterior pharyngeal wall augmentation using septal or conchal cartilages with other bulks-according to the persistent gap and the individual anatomy of each patient-in improving velopharyngeal function in patients who acquired persistent velopharyngeal insufficiency (VPI) post-adenoidectomy.
Methods: Observational descriptive prospective case series of 24 patients (their ages ranged between 3 and 26 years) who developed persistent VPI post-adenoidectomy (more than 3 months) although they had normal speech resonance before adenoidectomy.
Results: The present study demonstrated that statistically significant improvement in auditory perceptual assessment (APA) was found regarding all obligatory speech disorders and unintelligibility of speech.
Oxytocin-like receptor expression in evolutionarily conserved nodes of a vocal network associated with male courtship in a teleost fish.

Neuropeptides, including oxytocin-like peptides, are a conserved group of hormones that regulate a wide range of social behaviors, including vocal communication. In the current study, we evaluate whether putative brain sites for the actions of isotocin (IT), the oxytocin (OT) homolog of teleost fishes are associated with vocal courtship and circuitry in the plainfin midshipman fish (Porichthys notatus). During the breeding season, nesting males produce advertisement calls known as "hums" to acoustically court females at night and attract them to nests.

Purpose This study predicts and simulates the function and relative contributions of the intravelar and extravelar portions of the levator veli palatini (LVP) and palatoglossus (PG) muscles in velic constrictions. Method A finite element-based model of the 3-dimensional upper airway structures (palate, pharynx, tongue, jaw, maxilla) was implemented, with LVP and PG divided into intravelar and extravelar portions. Simulations were run to investigate the contributions of these muscles in velopharyngeal port (VPP) closure and constriction of the oropharyngeal isthmus (OPI).
