Summary
Velar palsy, or abnormal velar movement, is common in microtia patients, affecting 43% of those with isolated microtia and 80% with Oculo-Auriculo-Vertebral Spectrum (OAVS). This highlights the need for palate examination in all microtia cases.
Area of Science:
- Medical research
- Pediatric medicine
- Genetics and developmental biology
Background:
- Microtia, a congenital ear malformation, can be isolated or part of craniofacial anomalies, often associated with the Oculo-Auriculo-Vertebral Spectrum (OAVS).
- Velar abnormalities are known in OAVS, but their incidence in isolated microtia is understudied.
- Velopharyngeal insufficiency (VPI) resulting from velar palsy can impact speech development.
Purpose of the Study:
- To determine the prevalence of velar palsy in patients with isolated microtia versus those with microtia and OAVS signs.
- To identify potential risk factors for velar palsy in microtia patients.
Main Methods:
- Retrospective review of microtia patients presenting between January 2015 and March 2017.
- Extraction of medical images, palatal information, and demographic data from patient records.
Main Results:
- Velar palsy was observed in 43% of isolated microtia patients (18/42) and 80% of patients with microtia and OAVS signs (33/41).
- OAVS signs were independently associated with a significantly higher prevalence of velar palsy (OR: 4.8; 95% CI: 1.7-13).
Conclusions:
- A strong link exists between abnormal velar movement and microtia.
- Isolated microtia may represent a spectrum of OAVS, necessitating broader diagnostic considerations.
- Palate examination is crucial for all microtia patients to detect velar palsy and prevent speech development issues.

02:23Abnormal Proliferation
5.2K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

16.2K
Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist,...

Respiratory system abnormalities are a significant concern in healthcare due to their potential to indicate underlying severe conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, and pneumonia. These abnormalities can often be detected through physical examination methods like inspection and percussion.
Inspection Findings
During an inspection, several findings may suggest the presence of respiratory distress or disease. Pursed-lip breathing, where exhalation is slowed by...

01:43The Movement of Organelles and Vesicles
6.5K
In eukaryotic cells, cytoskeletal filaments such as actin, microtubules, and intermediate filaments form a mesh-like cytoskeletal network. These filaments serve as tracks for transporting cellular cargo. Specialized motor proteins use the chemical energy stored in adenosine triphosphate (ATP) for this transport. During interphase, microtubules are polarized, with the plus-end towards the cell periphery and the minus-end towards the cell center. Two microtubule-associated motor proteins,...

Auscultation, an essential part of a heart examination, is done using a stethoscope. It provides crucial information about heart function and possible heart problems. Due to heart problems, abnormal sounds can be heard during systole or diastole. These sounds include S3 and S4 gallops, opening snaps, systolic clicks, and murmurs.
