ow does a perforation of the eardrum occur? There are many ways an eardrum perforation can occur. An infection behind the eardrum in the middle ear may cause a rupture of the eardrum. Trauma to the ear may result from an object entering the ear canal and puncturing the eardrum. A traumatic blow to the ear with a cupped hand can rupture the eardrum. Hot welding slag can burn a hole through the eardrum. After a ventilation tube has been extruded or is removed, the opening usually closes; in some cases a permanent opening of the eardrum may occur. Chronic ear problems such as deep retraction pockets and cholesteatoma can weaken and erode the eardrum, resulting in a defect or perforation.

What is Laparoscopic Surgery:
Laparoscopic surgery describes procedures performed using one or multiple small incisions in the abdominal wall in contrast to the larger, normally singular incision of laparotomy. The technique is based around principles of minimally invasive surgery (or minimal access surgery): a large group of modern surgical procedures carried out by entering the body with the smallest possible damage to tissues. In abdominopelvic surgery, minimally invasive surgery is generally treated as synonymous with laparoscopic surgery as are procedures not technically within the peritoneal cavity, such as totally extraperitoneal hernia repair, or extending beyond the abdomen, such as thoraco-laparoscopic esophagectomy. The term laparoscopy is sometimes used interchangeably, although this is often reserved to describe a visual examination of the peritoneal cavity or the purely scopic component of a laparoscopic procedure. The colloquial keyhole surgery is common in non-medical usage.
Surgical Objective of Laparoscopic Surgery:
The objective of a laparoscopic approach is to minimize surgical trauma when operating on abdominal or pelvic structures. When correctly indicated and performed, this can result in smaller scars, reduced postoperative morbidity, shorter inpatient durations, and a faster return to normal activity. For a number of abdominopelvic procedures, a laparoscopic approach is now generally considered to be the gold-standard treatment option.

Developments of Laparoscopic Surgery:
Following a number of smaller-scale applications of minimally invasive techniques to abdominopelvic surgery, laparoscopic surgery became a major part of general surgical practice with the introduction of laparoscopic cholecystectomy in the 1980s and the subsequent pioneering of endoscopic camera technology. This led to the widespread adoption of the technique by the early- to mid-1990s. The portfolio of procedures that can be performed laparoscopically has rapidly expanded with improvements in instruments, imaging, techniques and training — forming a central component of modern surgical practice and cross-specialty curricula [2]. Techniques such as laparoscopically assisted surgery and hand-assisted laparoscopic surgery have allowed the application of laparoscopic techniques to a greater variety of pathology. Single-incision laparoscopic surgery, natural orifice transluminal endoscopic surgery, and minilaparoscopy-assisted natural orifice surgery continue to push forward the applications of minimally invasive abdominopelvic techniques; however, the widespread practice and specific indications for these remain to be fully established. More recently, robotic surgery has been able to build on laparoscopic principles through developments in visualization, ergonomics, and instrumentation.

When foreign organisms such as bacteria enter the body, the immune system sends white blood cells to fight the infection. This causes swelling (inflammation) at the site of infection and the death of nearby tissue, creating a hole called a cavity, which fills with pus to form an abscess.
A cervical biopsy is a procedure that is sometimes done on women during an exam called a colposcopy to remove cervical tissue for examination. It is also called a punch biopsy. It is usually performed when a Pap smear result is either inconclusive or abnormal and a doctor wants to screen further for any cervical dysplasia or cervical cancer.

results in less pain, fewer complications, earlier recovery, and a smaller scar. Colorectal cancer is the second leading cause of cancer death in the United States. For more information please visit our website: www.csamd.com or call (713)-790-0600.
aser treatment for scars reduces the appearance of scars. It uses focused light therapy to either remove the outer layer of the skin’s surface or stimulate the production of new skin cells to cover damaged skin cells. Laser treatment for scars can reduce the appearance of warts, skin wrinkles, age spots, scars, and keloids. It doesn’t completely remove a scar.
Peripheral arterial disease (P.A.D.) occurs when plaque (plak) builds up in the arteries that carry blood to your head, organs, and limbs. Plaque is made up of fat, cholesterol, calcium, fibrous tissue, and other substances in the blood. When plaque builds up in arteries, the condition is called atherosclerosis (ATH-er-o-skler-O-sis). Over time, plaque can harden and narrow the arteries. This limits the flow of oxygen-rich blood to your organs and other parts of your body. P.A.D. usually affects the legs, but also can affect the arteries that carry blood from your heart to your head, arms, kidneys, and stomach. This article focuses on P.A.D. that affects blood flow to the legs.
If you're pregnant, you're likely paying extra close attention to your body. If you happen to feel a cramp you may worry that it is a sign of a miscarriage. While the first trimester is the most common time for miscarriages, there are other reasons for cramps. Whether it signals a miscarriage depends on when it occurs, the severity of the cramping, and whether you're experiencing other symptoms alongside it.
