This document provides information about diagnostic nasal endoscopy including its indications, techniques, and complications. It is used to diagnose diseases of the nose, paranasal sinuses, and nasopharynx by examining all areas with an endoscope. Topical anesthesia is applied before inserting different sized endoscopes to visualize the nasal cavities, nasopharynx, sinuses and related structures. The endoscope is passed in multiple ways to thoroughly examine the nasal passages and related areas. Potential complications include bleeding that can be controlled with vasoconstrictor drops.
This document discusses various instruments used in otolaryngology. It describes instruments used in outpatient and operating room settings, and classifies them based on Spaulding classification as critical, semi-critical, or non-critical. It provides details on sterilization and disinfection methods for different instrument categories. Examples of specific instruments are given for examining ears, nose and throat, along with their uses and important features.
This document provides information about different laryngoscopy techniques. It begins with a brief history of laryngoscopy and then describes techniques such as indirect laryngoscopy using a mirror, direct laryngoscopy using a laryngoscope, and flexible and rigid fiber-optic laryngoscopy. Indirect laryngoscopy is described as the simplest examination method for visualizing the larynx and vocal cords. Flexible fiber-optic laryngoscopy allows for examination of the entire hypopharynx and larynx and is well-tolerated by patients. The document also covers laryngoscopy equipment, techniques, common mistakes, advantages and limitations of the different methods.
Coblation is a non-thermal tissue ablation technique that uses radiofrequency energy and saline to generate a precise plasma field. This plasma field breaks down tissue molecules with minimal damage to surrounding structures. Coblation was developed in the 1990s and is commonly used in ENT procedures like tonsillectomy, adenoid removal, and turbinate reduction due to benefits like bloodless dissection, precision, and reduced pain. The coblation system includes a wand, RF generator, foot pedal, and saline irrigation. The wand's electrodes and saline generate a localized plasma field for tissue removal in ablation mode or hemostasis in coagulation mode.

The document discusses Functional Endoscopic Sinus Surgery (FESS). FESS is a minimally invasive procedure that uses an endoscope to access and treat the paranasal sinuses. It aims to restore sinus function by re-establishing ventilation and mucociliary clearance. Key steps in FESS include uncinectomy to remove the uncinate process, maxillary antrostomy to access the maxillary sinus, and ethmoidectomy to access the ethmoid sinuses. Proper identification of anatomical landmarks like the middle turbinate, uncinate process, and bulla ethmoidalis is important for successful FESS.
Tympanoplasty is a surgical procedure to reconstruct the tympanic membrane and/or ossicles that have been damaged. It is classified based on the status of the ossicles and middle ear, such as the Wullstein and Austin-Kartush classifications, which help determine the surgical approach and predict success rates. Factors like the presence of otorrhea, perforation, cholesteatoma, and ossicular chain status are used to calculate a Middle Ear Risk Index that provides a prognosis for tympanoplasty outcomes.
1. Adenoidectomy is a surgical procedure to remove enlarged adenoids from the nasopharynx. It is often performed to treat conditions like snoring, sleep apnea, and recurrent ear infections.
2. The procedure is done under general anesthesia with the patient in the Rose's position. The adenoids are removed using curettes and forceps either through the mouth or using an endoscope. Hemostasis is achieved before closing.
3. Potential complications include bleeding, injury to nearby structures like the eustachian tube, and nasopharyngeal stenosis. The patient is monitored post-operatively for bleeding and discomfort before being discharged after 24 hours typically.
Boyle-Davis mouth gag and Doyen mouth's gag are used to keep the mouth open for various ENT surgeries. Denis Browne's tonsil holding forceps are used to hold and pull the tonsils during tonsillectomy. Thudicum nasal speculums are used in anterior rhinoscopy and nasal procedures to open the nasal cavity. Luc's forceps have sharp, cup-shaped blades and are useful for nasal and throat operations including submucous resection of the nasal septum.
Septoplasty is a surgical procedure to correct a deviated nasal septum. The nasal septum divides the nose into two cavities and provides structural support. Techniques for septoplasty have evolved over time from early excisions of entire septal segments to today's emphasis on preservation and realignment. A standard modern procedure recognizes mucosal preservation as a primary goal and uses a submucosal approach. Septoplasty is indicated when a deviated septum causes nasal obstruction or recurrent infections. Pre-operative testing such as acoustic rhinometry or rhinomanometry can evaluate the airway before septoplasty.

2. Common symptoms include choking, coughing, dysphagia, and respiratory distress. Diagnosis involves x-rays and endoscopy to locate and visualize the foreign body.
3. Treatment depends on the location and type of foreign body but typically involves rigid bronchoscopy or esophagoscopy to safely remove the object under general anesthesia. Observation may be adequate for blunt objects lodged in the esophagus.
This document provides an overview of the steps involved in primary sinus surgery via an endoscopic approach. It begins with a brief history of sinus surgery and then discusses preoperative assessment, including CT scans to evaluate sinus anatomy and disease patterns. The basic techniques of Messerklinger and Wigand are described. The key steps of the surgery are then outlined in detail, including uncinectomy, antrostomy of the maxillary sinus, anterior and posterior ethmoidectomy, sphenoid sinusotomy, and frontal sinusotomy when necessary. Throughout, anatomical landmarks and variations are discussed to guide safe dissection and avoid complications.
1) Nasal endoscopy is used to examine the nasal passages and paranasal sinuses using specialized equipment like rigid or flexible endoscopes and a light source.
2) The examination involves inserting the endoscope into the nasal cavity to visually inspect different areas like the inferior meatus, nasopharynx, sphenoethmoidal recess, and middle meatus.
3) Nasal endoscopy is useful for evaluating and treating inflammatory diseases of the sinuses, detecting tumors, locating the source of epistaxis, and assisting with other procedures like sinus surgery or skull base repairs. It provides information that CT scans cannot by allowing direct visualization of mucosal changes.
This document discusses various endoscopic procedures including laryngoscopy, bronchoscopy, and esophagoscopy. It provides indications for direct laryngoscopy including diagnostic examination and biopsy of suspected laryngeal malignancies as well as therapeutic procedures like foreign body removal. Micro-laryngoscopy is described as providing better illumination and precision compared to direct laryngoscopy but with some tradeoffs. Rigid and flexible bronchoscopy techniques are outlined noting rigid bronchoscopy allows procedures like foreign body removal but is more risky while flexible bronchoscopy can reach further into the lungs but not remove foreign bodies. Similarly, advantages and disadvantages of rigid versus flexible esophagoscopy are compared. Specific endoscopy positions, anatomy visualized, instruments used and potential complications are described
Direct laryngoscopy allows visualization of the larynx and hypopharynx. It is used diagnostically to examine these areas for lesions, growths, or foreign bodies and therapeutically to remove benign lesions, foreign bodies, or dilate laryngeal strictures. The patient is placed in a supine position with their head extended and neck flexed. A laryngoscope is lubricated and inserted past the tongue to lift the epiglottis and provide a view of the laryngeal structures. Potential complications include injury to the lips, tongue, or teeth as well as bleeding or laryngeal edema.
Total laryngectomy involves removal of the entire larynx. It has historically been performed since 1866, with improvements over time such as the two-stage procedure developed by Gluck to reduce mortality rates. Today it is generally reserved for advanced laryngeal cancers with extensive spread. The procedure involves mobilizing neck structures like the strap muscles and thyroid gland, dissecting and removing the larynx, and closing the resulting pharyngeal defect. Complications can include issues with the skin flap, pharyngocutaneous fistula, tracheal stenosis, and endocrine abnormalities.
The document discusses various laser and cryosurgery techniques used in ENT. It describes how lasers like CO2, KTP, and Nd:YAG use light amplification to cut, coagulate, and ablate tissue. Cryosurgery uses rapid freezing to below -30°C followed by slow thawing to destroy tissues. Both techniques are used to treat lesions, tumors, and other ENT conditions. Safety precautions are important as these techniques can damage surrounding normal tissues if not properly administered.
The document discusses various ear procedures including myringotomy, mastoidectomy, and tympanoplasty. Myringotomy involves incising the tympanic membrane to drain fluid from the middle ear, often used to treat acute otitis media. Mastoidectomy clears disease from the middle ear, epitympanum, and mastoid bone, creating a single cavity for drainage. Tympanoplasty aims to reconstruct the hearing mechanism after clearing chronic ear disease, and there are five types involving repair or reconstruction of different parts of the ear.
Mastoidectomy is a surgical procedure to access and treat infections of the mastoid air cells behind the ear. Over time, the procedure has evolved from simple cortical mastoidectomies described in the 17th century to more advanced techniques using an operating microscope and drill. Modern mastoidectomies are typically classified as canal wall up or canal wall down depending on whether the bony ear canal wall is preserved. Indications include treatment of cholesteatoma, refractory ear infections, and approaches for other inner ear procedures. The surgery involves an incision behind the ear to access and clean out the infected mastoid air cells.

Oropharyngeal airways are used to maintain the airway in unconscious patients and protect endotracheal tubes from being bitten. Nasopharyngeal airways are used for airway maintenance when oral airway placement is difficult. Endotracheal tubes are inserted into the trachea to provide a clear airway and facilitate mechanical ventilation. Tracheostomy tubes are inserted through an opening in the neck to provide a direct airway to the trachea.
This document discusses face masks, airways, laryngoscopes, endotracheal tubes, and extubation. Face masks are used for non-intubated ventilation and come in different sizes. Airways are inserted to prevent the tongue from falling back. Laryngoscopes are used to visualize the glottis and facilitate intubation, and come in different blade shapes like Macintosh and Miller. Endotracheal tubes are inserted into the trachea and come in different types and sizes. Extubation should be performed when respiration is adequate and during inspiration.
Storyboard on Acne-Innovative Learning-M. pharm. (2nd sem.) CosmeticsMuskanShingari
Â
Acne is a common skin condition that occurs when hair follicles become clogged with oil and dead skin cells. It typically manifests as pimples, blackheads, or whiteheads, often on the face, chest, shoulders, or back. Acne can range from mild to severe and may cause emotional distress and scarring in some cases.
**Causes:**
1. **Excess Oil Production:** Hormonal changes during adolescence or certain times in adulthood can increase sebum (oil) production, leading to clogged pores.
2. **Clogged Pores:** When dead skin cells and oil block hair follicles, bacteria (usually Propionibacterium acnes) can thrive, causing inflammation and acne lesions.
3. **Hormonal Factors:** Fluctuations in hormone levels, such as during puberty, menstrual cycles, pregnancy, or certain medical conditions, can contribute to acne.
4. **Genetics:** A family history of acne can increase the likelihood of developing the condition.
**Types of Acne:**
- **Whiteheads:** Closed plugged pores.
- **Blackheads:** Open plugged pores with a dark surface.
- **Papules:** Small red, tender bumps.
- **Pustules:** Pimples with pus at their tips.
- **Nodules:** Large, solid, painful lumps beneath the surface.
- **Cysts:** Painful, pus-filled lumps beneath the surface that can cause scarring.
**Treatment:**
Treatment depends on the severity and type of acne but may include:
- **Topical Treatments:** Such as benzoyl peroxide, salicylic acid, or retinoids to reduce bacteria and unclog pores.
- **Oral Medications:** Antibiotics or oral contraceptives for hormonal acne.
- **Procedures:** Such as chemical peels, extraction of comedones, or light therapy for more severe cases.
**Prevention and Management:**
- **Cleanse:** Regularly wash skin with a gentle cleanser.
- **Moisturize:** Use non-comedogenic moisturizers to keep skin hydrated without clogging pores.
- **Avoid Irritants:** Such as harsh cosmetics or excessive scrubbing.
- **Sun Protection:** Use sunscreen to prevent exacerbation of acne scars and inflammation.
Acne treatment can take time, and consistency in skincare routines and treatments is crucial. Consulting a dermatologist can help tailor a treatment plan that suits individual needs and reduces the risk of scarring or long-term skin damage.

Spontaneous Bacterial Peritonitis - Pathogenesis , Clinical Features & Manage...Jim Jacob Roy
Â
In this presentation , SBP ( spontaneous bacterial peritonitis ) , which is a common complication in patients with cirrhosis and ascites is described in detail.
The reference for this presentation is Sleisenger and Fordtran's Gastrointestinal and Liver Disease Textbook ( 11th edition ).
This presentation gives information on the pharmacology of Prostaglandins, Thromboxanes and Leukotrienes i.e. Eicosanoids. Eicosanoids are signaling molecules derived from polyunsaturated fatty acids like arachidonic acid. They are involved in complex control over inflammation, immunity, and the central nervous system. Eicosanoids are synthesized through the enzymatic oxidation of fatty acids by cyclooxygenase and lipoxygenase enzymes. They have short half-lives and act locally through autocrine and paracrine signaling.
Congestive Heart failure is caused by low cardiac output and high sympathetic discharge. Diuretics reduce preload, ACE inhibitors lower afterload, beta blockers reduce sympathetic activity, and digitalis has inotropic effects. Newer medications target vasodilation and myosin activation to improve heart efficiency while lowering energy requirements. Combination therapy, following an assessment of cardiac function and volume status, is the most effective strategy to heart failure care.
