Lingual thyroid

DIAGNOSIS-:LINGUAL THYROID-;-USG neck- no thyriod gland in neck::Tc99-isotope uptake in base of toungue area::Cause-faliure of migration of thyroid tissue as endodermal pouch through foramen of caecum and sequestration within the tongue substance::HYPERTROPHY of the gland occurs when requirement increases as in puberty,metabollic stress,pregnacy,infection,trauma,menopause:: In 70% of lingual thyriod cases absence of normal thyriod gland::Histologicaly resembles normal thyroid::Goiterogenous stimulus can cause colloidal changes::Conservative treatment to suppress TSH::Surgery-midline splitting dorsal tongue(per oral approach)::

ROBOTIC SURGERY IN ENT


There has been increasing interest in using robots to help the surgeon perform complex surgical procedures within small spaces thereby saving the patient more invasive incisions. Especially in the world of ENT, surgery that may have required large incisions to the face and/or neck can now be accomplished without any incisions by using robotics to perform the same surgery, but entirely through the mouth
Such robotic surgery performed through the mouth is called Trans-Oral Robotic Surgery, or simply TORS. The DaVinci system is the robotics platform that is most commonly used in TORS....
Using TORS and other approaches, head and neck surgeons have been able to remove the thyroid gland through the armpit, perform base of tongue cancer surgical excision (same cancer that Michael Douglas had), voicebox removal (laryngectomy), vocal cord surgery
In many of these and other surgeries, any procedure performed through the mouth traditionally was limited to two hands. With the DaVinci system, one technically can fit as many as FOUR "hands" inside the mouth enabling greater surgical flexibility and ease in performing fine dissections that otherwise would be impossible
There are some downsides however... namely, use of robotic surgery is not compensated by insurance and as such, major medical centers are the only locations where such high-tech equipment is available....

contraption designed to correct nasal deformity


A remarkable contraption designed to correct nasal deformity or septal deviation. It was completely ineffective and had only a brief window of popularity in France in the early 20th century. The metal device was held in position over the he...ad and nose with an elasticated band and the screws were then tightened so as, in theory, to correct any deviation from the midline. A rather beautifully engraved and and attractive little folly from medical history...

Cancer Patient Gets World's First Artificial Trachea


The patient, Andemarian Telesenbet Beyene, a 36-year-old geology student from Eritrea, had been suffering from late-stage tracheal cancer. A rare, aggressive tumor was blocking his windpipe making it hard for him to breath. Diagnosed in 200...8, Beyene had failed every conventional treatment including chemotherapy, radiation and surgery. He was running out of time, so rather than wait for a donor trachea for transplantation, his doctors suggested growing his own in the lab
This is not the first time a lab-engineered trachea has been used for transplantation. But in previous cases, the tracheas were built with donor organs. The donated tracheas were stripped of the donors' cells — leaving only the cartilage sc...affold — and then reseeded with stem cells derived from the recipients' own bone marrow. Once the stem cells took hold and grew on the scaffold, the tracheas could be transplanted into the patient without fear of rejection
Scientists created a Y-shaped framework for the new trachea, modeling it after the specific shape of the patient's windpipe. The form was made of polymers that had a spongy and flexible texture. Stiff rings around the tube mimicked the stru...cture of a human trachea.

The form was then bathed in a solution containing the patient's stem cells "to get the cells to grow on the sponge material," said David Green, president of Harvard Bioscience. Stem cells can divide and turn into a range of cell types, including those in organs
Polymer scaffold was made by Alexander Seifalian at University College London. The bioreactor that would hold the trachea and incubate it with Beyene's stem cells was created by Harvard Bioscience, near Boston. The scaffold and bioreact...or were then shipped to Stockholm, where the solution containing the patient's stem cells was added. The final product was days in the making, versus the months it could have taken to locate a donor organ
The artificial trachea was transplanted on June 9 in a 12-hour surgery led by Dr. Paolo Macchiarini, a pioneer in engineered trachea transplantation, at the Karolinska University Hospital in Stockholm. The patient appears to have accepted t...he new organ well, doctors said.

"It's working like a normal windpipe," Macchiarini told NPR's Shots blog. "He's able to cough. He's able to expel his secretions. He's breathing normally. He has the sensation he's breathing...
The cricoid cartilage, or simply cricoid (from the Greek krikoeides meaning "ring-shaped"), is the only complete ring of cartilage around the trachea...
The posterior part of the cricoid is slightly broader than the anterior and lateral parts, and is called the lamina, while the anterior part is the band; this may be the reason for the common comparison made between the cricoid and a signet ring
Cricoid is made up of hyaline cartilage..height of anterior lamina is 3-7mm and posterior lamina is about 20-30mm height..post surface of cricoid the post cricoarytenoid muscles are attached.When intubating a patient under general anesthes...ia prior to surgery, the anesthesiologist will press on the cricoid cartilage to compress the esophagus behind it so as to prevent gastric reflux from occurring: this is known as the Sellick manoeuvre
During Sellick manoeuvre cricoid pressure should not be more than 30N ...or can lead to fracture of cricoid cartilage..even linear fracture of the cricoid cartilage causes some resorption of cartilage and reduction of caliber of airway at t...he same level..resorption of cricoid cartilage can also be occured,if tracheostomy tube placed between cricoid and 1st ring...AS A GENERAL RULE INJURY TO CRICOID CARTILAGE HAS HIGEST INCIDENCE OF AIRWAY COMPROMISE...LEVEL OF CRICOID IS BETWEEN 5TH & 6TH CERVICAL VETEBRAL...
The Science of Nose-Picking:-Most everybody does it whether they admit it or not, both in kids and adults. In fact, according to one research survey, people do it about 4 times a day. In 7.6%, they do it >20 times a day! Nose-picking, also known as rhinotillexomania in medical-speak, generally is a benign, sedentary (and private) solo activity, but when excessive, can lead to a number of medical problems including nosebleeds (25% of nose-pickers), septal perforation, staph infections, etc. In one extreme case, it even led to a self-inflicted ethmoidectomy (sinus surgery)!!!!!!!!
