Swallow apnoea

Christian Guilleminault, Shehlanoor Huseni, Lauren Lo
A short lingual frenulum has been associated with difficulties in sucking, swallowing and speech. The oral dysfunction induced by a short lingual frenulum can lead to oral-facial dysmorphosis, which decreases the size of upper airway support. Such progressive change increases the risk of upper airway collapsibility during sleep. Clinical investigation of the oral cavity was conducted as a part of a clinical evaluation of children suspected of having sleep disordered breathing (SDB) based on complaints, symptoms and signs...

Mandibular distraction osteogenesis (MDO) is increasingly used for neonates and infants with upper airway obstruction secondary to micrognathia. This systematic review was conducted to determine the effectiveness of MDO in the treatment of airway obstruction. The databases searched included PubMed, Embase, Scopus, and grey literature sources. The inclusion criteria were applied to identify studies in children with clinical evidence of micrognathia/Pierre Robin sequence (PRS) who had failed conservative treatments, including both syndromic and non-syndromic patients...

A 22-year-old man presented to our department with a mass on the base of his tongue. He had a cavernous voice causing a moderate speech disorder, and he had some difficulty in swallowing. He had severe problems with sleep, associated with apnoea. In a fibreoptic laryngoscopic examination, a large 4×5 cm vascular mass was detected extending from the base of the patient's tongue to his epiglottis. It covered the epiglottis. Thyroid scintigraphy showed only thyroid tissue on the base of the tongue. Surgery was initiated transorally under the guidance of a rigid endoscope, but as the mass continued extended to the epiglottis, a transhyoid approach was taken...

Renal denervation is increasingly being adopted as a treatment option in patients with resistant hypertension. The long-term safety of this procedure is unknown. Though the procedure interrupts the sympathetic nerves at the renal level, it also has effects on other organ beds, notably the heart and vasculature. These effects have been purported to be clinically beneficial and thus formed a rationale for examining the role of renal denervation in other conditions, including heart failure, arrhythmia, obstructive sleep apnoea and the metabolic syndrome...

Tongue pressure data taken from healthy subjects during normal oral activities such as mastication, speech and swallowing are providing us with new ways of understanding the role of the tongue in craniofacial growth and function. It has long been recognized that the sequential contact between the tongue and the palate plays a crucial role in the oropharyngeal phase of swallowing. However, because the focus of most research on intraoral pressure has been on the generation of positive pressure by the tongue on the hard palate and teeth, generation and coordination of absolute intraoral pressures and regional pressure gradients has remained unexplored...

OBJECTIVE: To investigate the postoperative analgesic effects of parecoxib for uvulopalatopharyngoplasty (UPPP). METHODS: Patients with obstructive sleep apnoea syndrome who underwent UPPP were randomly divided into two groups. In group A, the incision-local block was performed with 5 ml of 0.5% ropivacaine injected subcutaneously before the end of surgery, then 20 ml of physiological saline was injected intravenously every 12 h for 2 days. In group B, in addition to the incision-local block, 40 mg parecoxib was injected intravenously 30 min before the end of UPPP and 40 mg parecoxib was injected intravenously every 12 h for 2 days...

BACKGROUND: With the idea of "replacing lost tissure with similar tissure in kind", vessel-pedicled palate mucosal flap, pedicled buccal musculomucosal flap and adjacent tongue musculomucosal flap could be the ideal approaches to soft palate reconstruction. AIM: To assess the adjacent tongue musculomucosal flap for soft palate reconstruction. PATIENTS AND METHODS: From August 2010 to July 2011, we applied tongue musculomucosal flap for soft palate reconstruction in three patients with Obstructive Sleep Apnoea/Hypopnoes Syndrome (OSAHS) in order to release OSAHS symptom by glossal volume reduction...

BACKGROUND: Many small, sick and premature infants are unable to coordinate sucking, swallowing and breathing, and therefore, require gavage feeding. In gavage feeding, milk feeds are delivered through a tube passed via the nose or mouth into the stomach. Intermittent bolus milk feeds may be administered using a syringe to gently push milk into the infant's stomach (push feed). Alternatively, milk can be poured into a syringe attached to the tube and allowed to drip in by gravity (gravity feed)...

OBJECTIVES: Short-term outcome and side effects after Uvulopalatopharyngoplasty (UPPP) are well recognized. However, there is a lack of knowledge of the long-term outcome and side effects after this surgery. This study was completed to investigate the outcome and side effects 20 years after UPPP for snoring and obstructive sleep apnoea. METHODS: Medical records of patients who underwent UPPP surgery for sleep apnoea and snoring between 1985 and 1991 were investigated retrospectively...

Obstructive sleep apnoea (OSA) is a disease that is characterised by recurrent pharyngeal obstruction during sleep. The pharynx is a hollow muscular tube lined with epithelium that performs the competing functions of breathing, where it is required to be open and swallowing where it is required to close. The mechanical process by which these large changes in luminal dimensions occur have not been considered, however in other biological tubes such as the oesophagus and the bronchial airways narrowing and closure occurs via folding of the mucosal surface...

Antrochoanal polyps are hyperplasias of the nasal mucosa, which have their origin in the maxillary sinus and extend through the nasal cavity and the choanae into the naso- and oropharynx. In children antrochoanal polyps represent one of the more frequent manifestations of paediatric nasal polyposis. Most studies on antrochoanal polyps in children report only on nasal obstruction, hyponasal speech and snoring, which are also encountered in the most common cause of obstructive sleep apnoea syndrome; i.e. adenoid or tonsillar hyperplasia...

A striking effect of stimulating the superior laryngeal nerve (SLN) is its ability to inhibit central inspiratory activity (cause ‘phrenic apnoea'), but the mechanism underlying this inhibition remains unclear. Here we demonstrate, by stimulating the SLN at varying frequencies, that the evoked non-respiratory burst activity recorded from expiratory laryngeal motoneurons (ELMs) has an intimate temporal relationship with phrenic apnoea. During 1–5 Hz SLN stimulation, occasional absences of phrenic nerve discharge (PND) occurred such that every absent PND was preceded by an ELM burst activity...

The coordination between nasal breathing and non-nutritive swallowing serves as a protective reflex against potentially asphyxiating material, i.e. saliva and secretions, entering the respiratory tract. Although this protective reflex is influenced by positional changes in the head and body, the effect of mandible position on this reflex is not fully understood. We examined the effect of mandible advancement associated with mouth opening on the coordination between nasal breathing and non-nutritive swallowing induced by continuous infusion of distilled water into the pharyngeal cavity...

New Zealand White (NZW) rabbits (n = 34) received intravenous propofol (16 +/- 5 mg/kg) for induction of anaesthesia followed by maintenance with sevoflurane (4.0 +/- 0.5%) in oxygen. All animals underwent ovariohysterectomy. Heart rate, respiratory rate, haemoglobin oxygen saturation, end-tidal carbon dioxide concentration, end-tidal sevoflurane concentration and oesophageal temperature were monitored every 5 min. Time from induction of anaesthesia to tracheal extubation and sternal recumbency were recorded as was the quality of recovery...

Vomiting involves the simultaneous violent contraction of abdominal and diaphragm muscles to produce a high pressure on the stomach. The heart right atrium forms a through path from IVC to SVC, so the high intra-abdominal pressure will drive blood from abdominal contents into the head. Normally internal viscous drags in organs will limit the volume leaving them during a single vomiting event. However, repetitive vomiting such as occurs in cyclic vomiting syndrome (CVS) may drive sufficient blood into head veins to produce extreme venous hypertension...

The coordination of swallowing and respiration is essential for a safe swallow. Swallowing consists of several subsecond events. To study this, it is important to use modalities with high temporal resolution. In this study, we have examined young healthy individuals with simultaneous videofluoroscopy, videomanometry and respiratory recording, all with high temporal resolution. The onset of 13 predetermined swallowing and respiratory events and the surrounding respiratory phase pattern were studied in different body positions and during different respiratory drives...
