A bilateral complete cleft lip, which has been previously treated with nasoalvoelar molding, is repaired with the Millard-Mulliken technique, which employs reconstruction of the orbicularis oris muscle by advancing bilateral muscular segments. This tutorial for medical professionals was developed to supplement learning of a common surgical technique and is not intended to replace formal surgical training. This slideshow is primarily intended for use on tablets or larger screens. Some detail might be lost on mobile screens.
A unique video confirming the reality of the introduction of a large amount of irrigant or drug solution into unoperated paranasal sinuses. How is the process of filling the paranasal sinuses in real time during the YAMIK procedure! The use of the YAMIK Nasal Catheter opens up incredible possibilities for the treatment of sinusitis in both children and adults.
Heart sounds are the noises generated by the beating heart and the resultant flow of blood through it. Specifically, the sounds reflect the turbulence created when the heart valves snap shut. In cardiac auscultation, an examiner may use a stethoscope to listen for these unique and distinct sounds that provide important auditory data regarding the condition of the heart. In healthy adults, there are two normal heart sounds often described as a lub and a dub (or dup), that occur in sequence with each heartbeat. These are the first heart sound (S1) and second heart sound (S2), produced by the closing of the atrioventricular valves and semilunar valves, respectively. In addition to these normal sounds, a variety of other sounds may be present including heart murmurs, adventitious sounds, and gallop rhythms S3 and S4. Heart murmurs are generated by turbulent flow of blood, which may occur inside or outside the heart. Murmurs may be physiological (benign) or pathological (abnormal). Abnormal murmurs can be caused by stenosis restricting the opening of a heart valve, resulting in turbulence as blood flows through it. Abnormal murmurs may also occur with valvular insufficiency (regurgitation), which allows backflow of blood when the incompetent valve closes with only partial effectiveness. Different murmurs are audible in different parts of the cardiac cycle, depending on the cause of the murmur.
Aortic valve replacement is a procedure in which a patient's failing aortic valve is replaced with an artificial heart valve. The aortic valve can be affected by a range of diseases; the valve can either become leaky (aortic insufficiency / regurgitation) or partially blocked (aortic stenosis).
During root canal treatment, the inflamed or infected pulp is removed and the inside of the tooth is carefully cleaned and disinfected, then filled and sealed with a rubber-like material called gutta-percha. Afterwards, the tooth is restored with a crown or filling for protection.
Both selegiline and rasagiline can improve the symptoms of Parkinson's disease, although their effects are small compared with levodopa. They can be used alongside levodopa or dopamine agonists. MAO-B inhibitors are generally very well tolerated, but can occasionally cause side effects, including: nausea.

By 5 weeks' gestational age, the wolffian (ie, mesonephric) and the müllerian (ie, paramesonephric) ducts have formed from intermediate mesoderm. In the absence of testosterone and müllerian inhibitory substance, the mesonephric ducts regress and the paramesonephric ducts continue to form the female reproductive structures with fusion of the distal portions of the paramesonephric ducts to give rise to the uterine fundus, the cervix, and the upper vagina. These developmental changes are genetically controlled in large part by a series of complex transcriptional signaling pathways including Wnt signaling, Hox genes, and many others. In a female fetus, the wolffian duct disappears except for nonfunctional vestiges. The müllerian duct is lined by a columnar epithelium. This includes the entire cervix and upper vagina to the vaginal plate (ie, sinovaginal bulb). Through a process of squamous metaplasia, the vagina and a variable portion of the ectocervix become covered with squamous epithelium. This process is complete by the fifth month of pregnancy.

Director of the Penn Orthopaedics Robotics and Navigation Program, Dr. Christopher Travers, discusses robotic joint replacement surgery, which is one of the multiple options that Penn Orthopaedics offers for joint replacement surgery. He walks through a robotic knee replacement surgery, discussing what the procedure is, how it differs from traditional joint replacement surgery, and the benefits.

Cerebral palsy is a disorder of movement, muscle tone or posture that is caused by damage that occurs to the immature, developing brain, most often before birth. Signs and symptoms appear during infancy or preschool years. In general, cerebral palsy causes impaired movement associated with abnormal reflexes, floppiness or rigidity of the limbs and trunk, abnormal posture, involuntary movements, unsteady walking, or some combination of these. People with cerebral palsy may have problems swallowing and commonly have eye muscle imbalance, in which the eyes don't focus on the same object. People with cerebral palsy also may suffer reduced range of motion at various joints of their bodies due to muscle stiffness. Cerebral palsy's effect on functional abilities varies greatly. Some affected people can walk while others can't. Some people show normal or near-normal intellectual capacity, but others may have intellectual disabilities. Epilepsy, blindness or deafness also may be present.
This video demonstrates how bronchoscopy and vocal cord mass injections can be performed under endoscopic guidance in a patient without any sedation. Only topical and local anesthesia is used for patient comfort.
Most scoliosis surgeons agree that children who have very severe curves (45-50° and higher) will need surgery to lessen the curve and prevent it from getting worse. The operation for scoliosis is a spinal fusion. The basic idea is to realign and fuse together the curved vertebrae so that they heal into a single, solid bone. With the tools and technology available today, scoliosis surgeons are able to improve curves significantly.
Cartilage is a slippery tissue that provides a smooth surface for joint motion and acts as a cushion between the bones. Synovium is soft, and it lines the joints. It produces fluid, called synovial fluid, for lubrication, and it supplies nutrients and oxygen to the cartilage. As these functions break down, they no longer protect the bones of the knee joint, and bone damage occurs. OA of the knee can cause pain and stiffness. The symptoms worsen over time
