Summary
A modified local infiltration (MMLI) method for endoscopic stapes surgery significantly reduces operative time, bleeding, and complications. This technique allows surgeons to observe vasoconstriction directly, improving surgical outcomes and patient safety.
Area of Science:
- Otolaryngology
- Surgical Innovation
- Minimally Invasive Surgery
Background:
- Stapes surgery is a common procedure for otosclerosis.
- Traditional methods may involve longer operative times and increased bleeding.
- Endoscopic approaches offer potential advantages but require optimized techniques.
Purpose of the Study:
- To introduce and evaluate a modified local infiltration (MMLI) technique for endoscopic stapes surgery.
- To assess the efficacy of MMLI in reducing surgical time, intraoperative blood loss, and complications.
- To compare outcomes between endoscopic and microscopic stapes surgery using MMLI.
Main Methods:
- A prospective study involving 70 patients undergoing stapes surgery for otosclerosis.
- Application of MMLI with simultaneous endoscopic visualization of vasoconstriction.
- Evaluation of operative time, blood loss, anatomical structure preservation, hearing outcomes, and complications.
Main Results:
- MMLI facilitated rapid bleeding control and a clear operative field.
- Endoscopic stapes surgery with MMLI showed significant reductions in operative time and blood loss compared to the microscopic approach.
- Less frequent scutum removal and reduced chorda tympani manipulation were observed in the endoscopic group.
Conclusions:
- This study reports the novel use of MMLI for endoscopic stapes surgery.
- The MMLI technique streamlines infiltration and visualization, eliminating the need for microscopes or frontal lamps.
- MMLI offers significant benefits, including reduced operative time and fewer complications in endoscopic stapes surgery.

2.0K
Depending on the target organ, local anesthetics (LAs) can be administered via various routes. In surface anesthesia, LAs are applied directly to the surface of the skin or mucous membranes. It is widely used for topical skin numbing before venipuncture or minor surgical procedures. Commonly used surface local anesthetics are lidocaine or benzocaine sprays or creams. Surface anesthesia occurs within 5 minutes and lasts for about 60 minutes. One of the main disadvantages of topical anesthesia is...

1.4K
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

A standard box and whisker plot informs us about the spread of the data in a given sample. One can identify the minimum value, maximum value, first quartile value, second quartile or median value, and third quartile.
However, the box plot does not tell the reader about outliers - values that lie far from the center of the data. We can modify the standard box and whisker plot to identify the outliers and visualize the actual spread of the data in a sample.
Initially, we calculate the adjusted...
