Modified nasopharyngeal tube for upper airway obstruction. (1/46)
A modified nasopharyngeal tube is described that does not add airway dead space and resistance, is well tolerated, highly successful, and allows simultaneous use of oxygen prongs. This potentially reduces the need for surgical intervention to relieve high upper airway obstruction from Pierre-Robin syndrome and other causes. (+info)Late presentation of upper airway obstruction in Pierre Robin sequence. (2/46)
A retrospective review was carried out of 11 consecutive patients with the Pierre Robin sequence referred to a tertiary paediatric referral centre over a five year period from 1993 to 1998. Ten patients were diagnosed with significant upper airway obstruction; seven of these presented late at between 24 and 51 days of age. Failure to thrive occurred in six of these seven infants at the time of presentation, and was a strong indicator of the severity of upper airway obstruction. Growth normalised on treatment of the upper airway obstruction with nasopharyngeal tube placement. All children had been reviewed by either an experienced general paediatrician or a neonatologist in the first week of life, suggesting that clinical signs alone are insufficient to alert the physician to the degree of upper airway obstruction or that obstruction developed gradually after discharge home. The use of polysomnography greatly improved the diagnostic accuracy in assessing the severity of upper airway obstruction and monitoring the response to treatment. This report highlights the prevalence of late presentation of upper airway obstruction in the Pierre Robin sequence and emphasises the need for close prospective respiratory monitoring in this condition. Objective measures such as polysomnography should be used, as clinical signs alone may be an inadequate guide to the degree of upper airway obstruction. (+info)The fetal mandible: a 2D and 3D sonographic approach to the diagnosis of retrognathia and micrognathia. (3/46)
OBJECTIVE: To define parameters that enable the objective diagnosis of anomalies of the position and/or size of the fetal mandible in utero. DESIGN: Fetuses at 18-28 gestational weeks were examined by two- and three-dimensional ultrasound. The study included normal fetuses and fetuses with syndromes associated with known mandible pathology: Pierre Robin sequence or complex (n = 8); hemifacial microsomia (Treacher-Collins syndrome, n = 3); postaxial acrofacial dysostosis (n = 1). Fetuses with Down syndrome (n = 8) and cleft lip and palate without Pierre Robin sequence or complex (n = 18) were also studied. Retrognathia was assessed through the measurement of the inferior facial angle, defined on a mid-sagittal view, by the crossing of: 1) the line orthogonal to the vertical part of the forehead at the level of the synostosis of the nasal bones (reference line); 2) the line joining the tip of the mentum and the anterior border of the more protruding lip (profile line). Micrognathia was assessed through the calculation of the mandible width/maxilla width ratio on axial views obtained at the alveolar level. Mandible and maxilla widths were measured 10 mm posteriorly to the anterior osteous border. RESULTS: In normal fetuses, the inferior facial angle was constant over the time span studied. The mean (standard deviation) value of the inferior facial angle was 65.5 (8.13) degree. Consequently, an inferior facial angle value below 49.2 degree (mean - 2 standard deviations) defined retrognathism. All the fetuses with syndromes associated with mandible pathology had inferior facial angle values below the cut-off value. Using 49.2 degree or the rounded-up value of 50 degree as a cut-off point, the inferior facial angle had a sensitivity of 1.0, a specificity of 0.989, a positive predictive value of 0.750 and a negative predictive value of 1.0 to predict retrognathia. In normal fetuses, the mandible width/maxilla width ratio was constant over the time interval studied. The mean (standard deviation) value was 1.017 (0.116). Consequently, a mandible width/maxilla width ratio < 0.785 defined micrognathism. Mandible width/maxilla width ratio values were below this cut-off point in eight and in the normal range in four fetuses with syndromes associated with mandible pathology. CONCLUSIONS: Retrognathia and micrognathia are conditions that can be separately assessed. The use of inferior facial angle and mandible width/maxilla width ratio should help sonographic recognition and characterization of fetal retrognathic and micrognathic mandibles in utero. (+info)Analysis of response covariationamong multiple topographies of food refusal. (4/46)
This study examined the effects of sequentially introducing treatment across multiple topographies of food refusal. Treatment with nonremoval of the spoon produced an increase in food acceptance and a decrease in disruption, but expulsion of food increased. When expulsion was treated, packing of food increased. Finally, when packing was treated, all refusal behaviors remained low, and acceptance continued to occur at high and stable levels. (+info)Rigid nasendoscope with video camera system for intubation in infants with Pierre-Robin sequence. (5/46)
We describe an alternative intubation technique using a rigid nasendoscope and a video camera monitor system in two infants with Pierre-Robin sequence presenting for palatoplasty. After induction with an inhalational anaesthetic technique, the tracheas of the infants could not be intubated with direct laryngoscopy using a Wisconsin blade. In the absence of a flexible paediatric fibrescope, a rigid endoscope (2.7 mm, 70 degrees lateral illumination) was passed orally to provide a view of the glottis on the monitor screen. A tracheal tube, bent into a J-shape using a stylet, was inserted orally and manipulated into the trachea, under video guidance. This technique proved to be simple, permitting a favourable view of the glottis. It should be considered for passing a tracheal tube through the vocal cords in infants who present with a difficult airway. (+info)The Stickler syndrome presenting as a dominantly inherited cleft palate and blindness. (6/46)
The Stickler syndrome is a newly recognized, but probably relatively frequent inherited generalized connective tissue disorder involving skeleton, eye, and oro-facial structures. A family with three affected generations is discussed. Severe myopia leading to blindness, cleft palate, or subnucous cleft, Pierre Robin anomaly, premature degenerative arthritis, or a family history of any of these indicates further evaluation. (+info)Fetal hydrocolpos leading to Pierre Robin sequence: an unreported effect of oligohydramnios sequence. (7/46)
The presence of distal atretic vagina causing accumulation of fluid and mucus secretions in the proximal vaginal cavity resulted in fetal hydrocolpos. Obstructive uropathy developed gradually because of direct compression of hydrocolpos on bilateral lower ureters, resulting in oligohydramnios from decreased urine formation. Oligohydramnios inhibited normal mandibular development with resulting cleft palate and glossoptosis (Pierre Robin Sequence). The development of sequence of events in this case indicates Pierre Robin Sequence as another effect of Oligohydramnios Sequence arising out of deformational forces acting on cranio-facial structures. (+info)Collagen XI sequence variations in nonsyndromic cleft palate, Robin sequence and micrognathia. (8/46)
Cleft palate is a common birth defect, but its etiopathogenesis is mostly unknown. Several studies have shown that cleft palate has a strong genetic component. Robin sequence consists of three of the following four findings: micrognathia, glossoptosis, obstructive apnea, and cleft palate. While cleft palate is mainly nonsyndromic, about 80 percent of Robin sequence cases are associated with syndromes. Mutations in genes coding for cartilage collagens II and XI, COL2A1, COL11A1 and COL11A2, have been shown to cause chondrodysplasias that are commonly associated with Robin sequence, micrognathia or cleft palate. We therefore analyzed a cohort of 24 patients with nonsyndromic Robin sequence, 17 with nonsyndromic cleft palate and 21 with nonsyndromic micrognathia for mutations in COL11A2. A total of 23 Robin sequence patients were also analyzed for mutations in COL2A1 and COL11A1. We detected two disease-associated mutations in patients with Robin sequence, an Arg to stop codon mutation in COL11A2 and a splicing mutation in COL11A1. Two putatively disease-associated sequence variations were found in COL11A1 in Robin sequence patients, one in COL11A2 in a patient with micrognathia and one in COL2A1 in two patients with Robin sequence. The results showed that sequence variations in these genes can play a role in the etiology of Robin sequence, cleft palate and micrognathia but are not common causes of these phenotypes. (+info)Pierre Robin Syndrome is a congenital condition characterized by a set of distinctive features including:
1. Micrognathia: This is the term for an abnormally small lower jaw (mandible). In Pierre Robin Syndrome, this feature is present at birth and can lead to breathing difficulties due to the tongue falling back and obstructing the airway.
2. Glossoptosis: This refers to the displacement of the tongue towards the back of the mouth. Because of the small jaw, the tongue has limited space and tends to fall back and block the airway, especially during sleep.
3. Cleft Palate: A cleft palate is a birth defect where there is an opening in the roof of the mouth (palate). This occurs because the two sides of the palate do not fuse together properly during fetal development.
The syndrome can vary in severity among individuals, and some may also have other associated conditions such as hearing problems, heart defects, or learning disabilities. The exact cause of Pierre Robin Syndrome is unknown, but it's often associated with genetic syndromes like Stickler syndrome and velocardiofacial syndrome. Treatment typically involves addressing the airway issues first, often through positioning, prone sleeping, or in severe cases, a surgical procedure to bring the jaw forward (distraction osteogenesis). The cleft palate is usually repaired with surgery within the first year of life.
Micrognathism is a medical term that refers to a condition where the lower jaw (mandible) is abnormally small or underdeveloped. This can result in various dental and skeletal problems, including an improper bite (malocclusion), difficulty speaking, chewing, or swallowing, and sleep apnea. Micrognathism may be congenital or acquired later in life due to trauma, disease, or surgical removal of part of the jaw. Treatment options depend on the severity of the condition and can include orthodontic treatment, surgery, or a combination of both.
A palatal obturator is a type of dental prosthesis that is used to close or block a hole or opening in the roof of the mouth, also known as the hard palate. This condition can occur due to various reasons such as cleft palate, cancer, trauma, or surgery. The obturator is designed to fit securely in the patient's mouth and restore normal speech, swallowing, and chewing functions.
The palatal obturator typically consists of a custom-made plate made of acrylic resin or other materials that are compatible with the oral tissues. The plate has an extension that fills the opening in the palate and creates a barrier between the oral and nasal cavities. This helps to prevent food and liquids from entering the nasal cavity during eating and speaking, which can cause discomfort, irritation, and infection.
Palatal obturators may be temporary or permanent, depending on the patient's needs and condition. They are usually fabricated based on an impression of the patient's mouth and fitted by a dental professional to ensure proper function and comfort. Proper care and maintenance of the obturator, including regular cleaning and adjustments, are essential to maintain its effectiveness and prevent complications.
Mandibulofacial dysostosis is a genetic disorder that affects the development of the face and jaw. It is characterized by underdevelopment of the lower jaw (mandible) and facial bones, which can result in distinctive facial features such as a small chin, cleft palate, hearing loss, and dental abnormalities. This condition is often associated with other health issues, including respiratory problems and developmental delays. Mandibulofacial dysostosis is typically inherited in an autosomal dominant pattern, which means that only one copy of the altered gene is necessary to cause the disorder. It can also occur spontaneously due to a new genetic mutation. The specific symptoms and severity of mandibulofacial dysostosis can vary widely from person to person.
In dental terminology, "space maintenance" refers to the use of a device or appliance to maintain the proper space between teeth following the loss of a primary (baby) tooth. This is especially important when the lost tooth is a molar, as it plays a crucial role in maintaining the alignment and spacing of the remaining teeth and the eruption path for the developing permanent tooth.
Space maintainers can be fixed or removable and are typically made from materials such as stainless steel, plastic, or acrylic. They help prevent dental issues like crowding, misalignment, and impaction of adjacent and/or succeeding teeth, which may lead to more complex orthodontic treatments in the future. It is essential that space maintainers are custom-made and properly fitted by a dentist or an orthodontist to ensure their effectiveness and avoid potential damage to surrounding tissues.
The "chin" is the lower, prominent part of the front portion of the jaw in humans and other animals. In medical terms, it is often referred to as the mentum or the symphysis of the mandible. The chin helps in protecting the soft tissues of the mouth and throat during activities such as eating, speaking, and swallowing. It also plays a role in shaping the overall appearance of the face. Anatomically, the chin is formed by the fusion of the two halves of the mandible (lower jawbone) at the symphysis menti.
Airway obstruction is a medical condition that occurs when the normal flow of air into and out of the lungs is partially or completely blocked. This blockage can be caused by a variety of factors, including swelling of the tissues in the airway, the presence of foreign objects or substances, or abnormal growths such as tumors.
When the airway becomes obstructed, it can make it difficult for a person to breathe normally. They may experience symptoms such as shortness of breath, wheezing, coughing, and chest tightness. In severe cases, airway obstruction can lead to respiratory failure and other life-threatening complications.
There are several types of airway obstruction, including:
1. Upper airway obstruction: This occurs when the blockage is located in the upper part of the airway, such as the nose, throat, or voice box.
2. Lower airway obstruction: This occurs when the blockage is located in the lower part of the airway, such as the trachea or bronchi.
3. Partial airway obstruction: This occurs when the airway is partially blocked, allowing some air to flow in and out of the lungs.
4. Complete airway obstruction: This occurs when the airway is completely blocked, preventing any air from flowing into or out of the lungs.
Treatment for airway obstruction depends on the underlying cause of the condition. In some cases, removing the obstruction may be as simple as clearing the airway of foreign objects or mucus. In other cases, more invasive treatments such as surgery may be necessary.
