Introduction Over the past decade, periradicular surgery has continued to evolve into a precise, biologically based adjunct to nonsurgical root canal therapy. Although nonsurgical endodontic treatment gives good results in most cases, surgery may be indicated for teeth with persistent periradicular pathoses that have not responded to nonsurgical approaches Indications : As an alternative to the cold lateral compaction technique. When the fitting of a conventional master cone to the apical portion of the canal is impossible, as when there is a ledge formation, perforation, or unusual canal curvatures, internal resorptions, or large lateral canals World's Best PowerPoint Templates - CrystalGraphics offers more PowerPoint templates than anyone else in the world, with over 4 million to choose from.

When the latter technique was used, almost no late post-operative complications were seen, but with the conventional technique various complications, local infections, increased pocket depth. Two-hole trephination was planned to remove the osteoma using nasal endoscope and a drill in each hole. Results: The osteoma was drilled and removed transnasally. Two months later, two small fragments of osteoma were detected remaining in the lateral aspect of the sinus. The fragments were removed successfully with the same technique. The patien

The purpose was often the procurement of the bone itself as a fetish object, but in other cases was performed medically to relieve pain or pressure, as therapy for skull fractures, or to cure.

Lateral hip pain associated with trochanteric bursitis is a common orthopedic condition, and can be debilitating in chronic or recalcitrant situations. Conservative management is the most common initial treatment and often results in resolution of symptoms and improved patient outcomes. These modalities include rest, activity modification, physical therapy, anti-inflammatory medication, or. Caldwell-Luc surgery, as it became known, was the primary workhorse for maxillary sinus disease until the 1920s, when intranasal procedures gained in popularity.

  1. Pericardiocentesis is the most useful therapeutic procedure for the early management or diagnosis of large, symptomatic pericardial effusion and cardiac tamponade. [1] The first description of cardiac decompression was in 1653, when Riolanus suggested sternal trephination to relieve pericardial pressure
  2. A craniotomy is the surgical removal of part of the bone from the skull to expose the brain. Specialized tools are used to remove the section of bone called the bone flap. The bone flap is temporarily removed, then replaced after the brain surgery has been done. Some craniotomy procedures may use the guidance of computers and imaging (magnetic.
  3. The incidence of lateral meniscus posterior root tears was 4 times higher than medial in both primary and revision subsets. The authors also assessed the healing of meniscal tears when repaired during 2-stage ACL revision reconstruction, finding a healing rate of 82.3% for root tears repaired with a transtibial technique
  4. Temporary trephination and non-invasive infusion. Alternative techniques aimed to avoid prolonged hospitalisation and potential complications. Frontal sinus trephination for temporary catheterisation (Fig 8) was the first of these to be described (Davidson and others 1992)
  5. Using an outside-in technique, the anterior horn of the meniscus (white arrow) is fixed with an 18-gauge spinal needle and a metal suture shuttling device. Fig 8 Left knee viewing from medial portal. An arthroscopic probe is used to test the fixation of the medial meniscus transplant
  6. Anesthetics. Currently, several techniques are used in clinical practice, mainly divided into 2 groups: (1) Asleep-awake-asleep. The patient will have GA with laryngeal mask airway/endotracheal tube (LMA/ETT) for the craniotomy and closure but awakened and extubated for mapping and resection. (2) Awake-awake-awake

The dorsal and ventral rhinocenteses are indicated by a white and black circle, respectively

Treatment options for meniscal tears fall into three broad categories; non-operative, meniscectomy or meniscal repair. Selecting the most appropriate treatment for a given patient involves both patient factors (e.g., age, co-morbidities and compliance) and tear characteristics (e.g., location of tear/age/reducibility of tear).There is evidence suggesting that degenerative tears in older. The laser level device should be in line with the patient's Foramen of Monro (FOM). If the patient is supine with their head neutral, level the EVD system to the tragus of the ear. If the patient is lateral, level the EVD to the mid sagittal line (between the eyebrows). Every time the patient moves the EVD must be re-levelled trephination because primitive trephination techniques are dangerous in this area due the proximity of the middle meningeal arteries. An alternative cause for the defect is that the hole could have been made by a probe long after the individual was buried.

Patella tendinopathy is defined as pain and dysfunction in the patella tendon. Clinically, patella tendinopathy presents with localised anterior knee pain and pain with loading tasks such as stairs, jumping, squats, sit to stand, and prolonged sitting (Rudavsky & Cook., 2014). The following clinical features help support our clinical reasoning. Simple augmentation techniques including trephination, rasping, and abrasion of the synovium have been shown to improve healing in repaired meniscal tears. Techniques such as fibrin clots sutured at the meniscus repair site, and PRP used either alone or with a variety of scaffolds, have given equivocal evidence in clinical studies Nail trephination is the process of making a hole in a nail to drain a subungual hematoma. Nail trephination is most likely to be successful if performed within 48 hours of injury. Acrylic nails (flammable!) The most common methods of trephination are with electrocautery or using a needle to bore through the nail

Burr holes are used to help relieve pressure on the brain when fluid, such as blood, builds up and starts to compress brain tissue. A layer of thin tissues called meninges surround and help protect the brain. These meninges contain blood vessels that carry blood to and from the brain. The dura is the outermost of these meninges technique. Recent evidence suggests that prophylactic antibiotics are not necessary unless the nail plate is removed.2 There has been controversy of late as to whether patients who present with subungual hematomas can be treated simply with trephination or whether complete removal of the nail plate with repair of the nail bed necessary A nice looking fingernail is an important cosmetic goal when dealing with traumatic lacerations and crush injuries to the fingertip. But there's more to these injuries than just cosmetics. An intact fingernail allows us to more finely grasp small objects; it improves tactile sensation; it even helps regulate circulation to the distal fingertip

Acute frontal sinusitis is considered a more serious type of acute sinus infection because of its complications, with the frontal sinus being the one that is most commonly associated with intracranial infection. Frontal sinus surgery is performed to prevent potentially life-threatening complications when the infection is unresponsive to maxim.. from the bone surface. Corneal trephination is carried out (5mm diameter) to form a central opening in the eye, removing the iris lens and the anterior vitreous. Incision is made to relieve and there is a complete removal of the iris. Posterior of the lamina is placed through the central hole. The lamina is sutured onto the cornea and sclera • After trephination: - Lavage until no more exudate - 3-5 days 2 x daily with 1 L of warmed saline through foley catheter placed at trephination. • Antibiotics - The use of systemic antibiotic therapy depends on the primary disease and should be based on bacterial cultures and antibiotic sensitivity results.

Academia.edu is a platform for academics to share research papers Surgeons can use various techniques to treat subdural hematomas: Burr hole trephination. A hole is drilled in the skull over the area of the subdural hematoma, and the blood is suctioned out. Over 600,000 people undergo knee replacement surgery every year in the United States. Severe complications, such as an infection, are rare. They occur in fewer than 2 percent of cases. Relatively. The frontal sinus is irregularly shaped and scalloped at its margins. Asymmetry of the sinus is the rule rather the exception (10% of individuals have a unilateral sinus, 9% of individuals have a rudimentary or absent sinus).
