Lower Eyelid Malposition & Ectropion Lower eyelid malposition is the most common complication of lower blepharoplasty medicine reminder app buy 200ml liv 52. It occurs after excessive skin removal or other weakening maneuver on the lower lid medicine 2632 buy genuine liv 52 line. Mild malposition preferentially occurs laterally treatment 02 bournemouth discount 100ml liv 52 fast delivery, resulting in inferior bowing of the lateral lid acute treatment generic 200 ml liv 52, called "rounding. It usually requires surgical correction either with horizontal lid shortening, muscle suspension, or full-thickness skin grafting. The upper lateral cartilages are not only juxtaposed to the nasal bones here, but there is actual overlap among them. Unlike the nasion and rhinion, which correspond to exact anatomic landmarks, the radix or the root of the nose refers to a general location. Upper Cartilaginous Vault the upper cartilaginous vault comprises the upper lateral cartilages. The cephalic border is relatively immobile because of the fusion of the upper lateral cartilages to the fixed quadrangular cartilage of the septum and the overlap with bone at the keystone area. Laterally, the upper lateral cartilages are fused to the pyriform aperture by dense fibroareolar tissue and are attached to the alar cartilages caudally. The caudal edge of the upper lateral cartilage curves in the same direction as the overlapping cephalic edge of the alar cartilage, creating the scroll. In many ways, the bony pyramid and the upper lateral cartilage act as a single osseocartilaginous unit. The thickened caudal border of the upper lateral cartilage acts as the internal nasal valve and moves with the respiratory cycle in a paradoxical fashion. With inspiration, the respiratory muscles create negative pressure within the entire upper respiratory tract. This causes the internal nasal valve to narrow and increases air resistance and modifies currents to maximize exposure to nasal mucosa. At the same time in the lower cartilaginous vault, the nostrils flare, increasing the diameter of the external nasal valve. Bony Vault the bony vault is made up of the nasal bones and the nasal processes of the maxilla. The nasal bones are widest at the nasofrontal suture, become narrowest at the nasofrontal groove, and then become wide again at the rhinion. The dorsal border of the septum fuses with the caudal end of the nasal bones so that the septum acts like a rigid and fixed beam on which the cartilaginous structures are suspended. The nasion refers to the nasofrontal suture, where the nasal bones fuse with the frontal process. The rhinion is where the caudal border of the nasal bones meets 910 Lower Cartilaginous Vault the lower lateral cartilages or alar cartilages are responsible for the support and configuration of lower third of the nose. They are connected laterally to the sesamoid (accessory) cartilages, the pyriform aperture, and to the upper lateral cartilages. They run along the caudal septum to the apex of the nostril and diverge anteriorly. The most posterior portion, called the medial crural footplates, extends toward but not to the nasal spine. They do, however, tightly sandwich the caudal septum, a relationship that is important for tip support. The intermediate or middle crura form the bridge between the medial and lateral crura. The point at which the medial crura diverge is most commonly considered the start of the intermediate crura. This bend in the alar cartilage is called the point of divergence or the medial genu.

Root Conditioning A primary goal of periodontal therapy is to treat the diseased root surface making it biologically compatible with a healthy periodontium medicine x protein powder order liv 52 60 ml with visa. This includes removing the endotoxins, bacteria, and other antigens found in the cementum of the root surface. Another form of root conditioning used to help achieve this goal and facilitate new attachment is root surface demineralization. In a review article, Holden and Smith (1983) state that root conditioning was performed as early as 1883 when Marshall placed aromatic sulfuric acid on root surfaces, Younger used lactic acid in 1897, and in 1899 when Stewart decalcified the root surface with pure hydrochloric or sulfuric acid. It was determined that citric acid at pH 1 for 2 to 3 minutes would be the best agent. They later showed the formation of cementum pins (perpendicularly extending fiber bundles seen in the tubules at 3 weeks, which appear continuous with and inseparable from the induced cementum at 6 weeks) extending into dentin tubules widened by demineralization when denuded root surfaces in dogs were treated by citric acid pH 1 for 2 minutes. Scanning microscopy showed acid decreased the surface characteristics of non-root planed teeth. Acid-etched root planed surfaces were flat with frequent depressions and numerous fiber-like structures. Transmission microscopy revealed root planed and acid-etched surfaces produced a zone of demineralization of 4 um wide. When these surfaces were treated by citric acid (pH 1 for 3 minutes) this smear layer was removed. The result was a fibrous matlike structure with a fibrillar texture having numerous funnel-shaped depressions corresponding to open dentinal tubules. They examined the dentinal surfaces for root roughness and maximal exposure of the collagen surface. The burnished specimens were found to have patent dentinal tubules and an intertubular area with a very distinct "shag carpet" appearance of deeply tufted collagen fibrils. The passively placed citric acid specimen exhibited open dentinal tubules with a matted collagen surface. They proposed that the burnishing application removed more inorganic material through a combined mechanical/chemical process while fluffing and separating the entangled fixed dentin collagen. They showed that acid-treated teeth had a fibrillar zone 3 to 8 um thick consisting of collagenous fibrils of the dentin exposed during acid treatment. There appeared to be a layer of cells in dynamic activity and distinct attachment to dentin with cells migrating over the root surface. In the controls, there were large areas devoid of cells and other connective tissue components. This suggests that citric acid treatment may result in fibrin clot stabilization and initiate wound healing that results in new connective tissue attachment. They found that: 1) root planing improves diseased roots and that root planing followed by citric acid demineralization improves diseased roots to a level comparable to non-diseased roots; 2) citric acid demineralization alone improves diseased roots to a level comparable to root planed diseased roots; and 3) acid demineralization results in both collagen fiber exposure and a more hospitable environment. They found that passive applications for 5 minutes and burnished applications for 3 minutes both produced seemingly optimal surface characteristics consisting of a fine, fibrillar network of exposed collagen and a reduced or eliminated smear layer. Citric acid pH 1 was applied to dentin surfaces prepared from extracted teeth by 1) immersion; 2) placement of saturated cotton pellets; 3) burnishing with cotton pellets; or 4) camel hair brush. Immersion demonstrated tufting of intertubular dentin fibrils and wide open dentinal orifices. Pellet placement revealed a more matted surface and some debris inside the orifices. Two of 8 slabs showed tufting with widened tubular openings, while 6 of 8 showed surface smearing with complete obturation of the tubules. The camel hair brush resulted in surface characteristics close to those treated by immersion (tufting with widened tubules). Immersion resulted in the greatest number of openings followed by cotton pellet placement and camel hair brush. The measurements of calcium parts per million released for citric acid concentrations of 0, 10, 20, 25, 30, 35, 40, and 65% were determined at 1, 2, and 3 minutes. Denuded root surfaces healed with cementogenesis with a secure fiber attachment at 6 weeks.

Although infection may ensue medicine 44334 discount liv 52 online amex, primary closure is still recommended for these wounds after thorough irrigation and with concomitant antibiotic administration medicine 513 safe liv 52 120 ml. The antibiotic coverage should be directed at a polymicrobial spectrum including hemolytic streptococci medications peripheral neuropathy cheap liv 52 uk, Staphylococcus aureus medicine 123 generic liv 52 100ml fast delivery, and anaerobes such as Bacteroides. Typically, injectable 1% lidocaine with epinephrine mixed 1:100,000 is adequate to obtain anesthesia for closure. This preparation can be injected with a fine, 27-gauge needle and a control-type syringe. During the procedure, it is often possible to keep the patient comfortable with a small amount of sedation if no contraindication exists. Wound Irrigation Once anesthesia takes effect, the wound should be irrigated to help prevent future infection. If glass, gravel, or other foreign material is suspected to be in the wound, a finger can be used to probe the wound and remove the foreign material. Sometimes the skin is abraded so badly that the area needing to be anesthetized would be too large to safely administer lidocaine to the patient without causing lidocaine toxicity. In some wounds contaminated by tar, as sometimes occurs in motorcycle accidents or other road injuries, administering general anesthesia is the best recommended option for wound manipulation that is comfortable for the patient. Once the wound is thoroughly clean, povidone-iodine, commonly known as Betadine, can be used to create a sterile environment for wound closure. Any small bleeding areas can be handled with a disposable electric cautery or by using individual clamps and suture ties. A severe laceration may sometimes require general anesthesia to properly identify cut nerves and provide a stable condition for operative closure. It is likely that the result will be no worse if an attempt at closure is made, even if the wound eventually becomes infected compared with leaving the wound open to heal by second intention. Special attention must be directed to evaluation of the airway because airway obstruction may develop rapidly after inhalation injury. Specific risk factors for airway compromise include a history of burn injury within a confined space, evidence of soot in the oral cavity, production of carbonaceous sputum, and concomitant facial and body burns. Laboratory evidence, including arterial blood gases and carboxyhemoglobin levels, may further suggest potential airway impairment. If time permits, serial flexible fiberoptic nasolaryngoscopy exams allow for diagnosis of oropharyngeal, true and false vocal fold edema. In management of burn patients, there should be a low threshold for early intubation. First-degree burns involve the epidermis only (eg, sunburn), and clinical findings include erythema. Second-degree or partial-thickness burns involve the epidermis and a portion of the dermis. These burns are extremely painful and present with blistering and open, weeping surfaces of skin. As such, they are characterized as insensate, swollen, and white or gray in color. Extent of burn injury is estimated by the "rule of nines," whereby the head and neck region represents approximately 9% of total body surface area. Inpatient management is universally required for second- or third-degree burns of the face. Early treatment goals involve the prevention of infection via sterile dressings, burn excision, and wound closure if permissible. To attenuate contracture and scar formation, temporary wound cover may be accomplished with cadaver grafts, porcine grafts, and a variety of synthetic skin substitutes. Permanent wound coverage is obtained by split-thickness skin grafts, local flaps, or microvascular free tissue transfer. Microstomia commonly results from perioral facial burns, or thermal burns that occur when small children chew electric cords. Oral splints are available for prevention of microstomia, but the efficacy of these appliances is controversial.

There appears to be no significant difference in perioperative complications or pain after surgery in these patients symptoms rheumatoid arthritis order liv 52 in india. Deep neck infections-Deep neck infections as a complication of bacterial tonsillitis or pharyngitis continue to occur at a significant rate in most regions medicine for depression purchase liv 52 200ml with visa. In decades past medicine etodolac purchase 60 ml liv 52 with amex, the most common cause of parapharyngeal abscesses was bacterial pharyngitis or tonsillitis medicine woman strain buy generic liv 52 120 ml line. With the widespread use of antibiotics, the incidence of these complications has dramatically decreased. However, patients who present with severe symptoms of odynophagia, trismus, and shortness of breath need careful evaluation to rule out this serious complication. Examination may reveal asymmetric pharyngeal swelling, including the palate, but this swelling extends more inferiorly than the tonsil into the hypopharynx. Classically, these patients also have "woody," diffuse neck swelling, but in some cases this phenomenon appears only as the infection progresses. In most cases, management includes control of the airway, intravenous antibiotics, and surgical drainage of the abscess. Chronic adenotonsillar hypertrophy-Lymphoid tissue of the Waldeyer ring is very small in infants. It increases in size by the time the child is 4 years of age in association with immunologic activity, since tonsils and adenoids are the first lymphoid organs in the body to encounter ingested and inhaled pathogens. Tonsillar and adenoid tissue has many specialized immunologic compartments responsible for humoral and cellular immune response, such as crypt epithelium, lymphoid follicles, and extrafollicular regions. Therefore, hypertrophy of the lymphoid tissue as a whole occurs in response to colonization with normal flora as well as with pathogenic microorganisms. Second-hand smoke exposure in the home environment has also been linked to adenotonsillar hypertrophy. Nasal obstruction, rhinorrhea, and a hyponasal voice are the usual presenting symptoms of adenoid hypertrophy, whereas tonsillar enlargement can cause snoring, dysphagia, and either a hypernasal or a muffled voice. Upper airway obstruction can manifest as loud snoring, chronic mouth breathing, and secondary enuresis. A history of witnessed apneic episodes, hypersomnolence or hyperactivity, frequent nighttime awakenings, poor school performance, and a general failure to thrive are common manifestations of obstructive sleep apnea. Adenotonsillar hypertrophy and chronic mouth breathing due to nasal obstruction are associated with craniofacial growth abnormalities in children and can lead to the development of an increased anterior facial height and a retrognathic mandible, with subsequent malocclusion. The diagnosis of adenotonsillar hypertrophy is based on the clinical history and physical examination. Craniofacial abnormalities, other causes of nasal obstruction, and the degree and symmetry of tonsillar hypertrophy should be assessed. The hard and soft palates should be examined carefully to rule out a submucous cleft palate, which would predispose the patient to the postoperative development of velopharyngeal insufficiency. Lateral neck soft tissue radiography can be helpful in documenting hypertrophic adenoids if endoscopy is not performed. Because of the difficulties in performing sleep studies in young children, the use of polysomnography to document obstructive sleep apnea in these patients remains controversial. This test is usually reserved for patients without a clear history whose examination is consistent with obstruction or for patients with craniofacial anomalies and neurologic disorders. Craniofacial morphology in preschool children with sleep-related breathing disorder and hypertrophy of tonsils. Pediatric autoimmune neuropsychiatric disorders and streptococcal infections: role of otolaryngologist. When this finding is accompanied by a suspicious clinical course or history, a tonsillectomy should be performed for biopsy. Many primary malignant neoplasms (eg, melanoma and renal cell, lung, breast, gastric, and colon carcinomas) have been reported to metastasize to the tonsil. Benign tumors of the tonsil are rare and they include lipomas, fibromas, and schwannomas. Parapharyngeal space tumors are important to consider as a diagnosis, since they may present with signs and symptoms mimicking an asymmetric tonsillar hypertrophy or a tonsillar abscess. The predictive value of a malignant process is increased when tonsillar asymmetry is associated with rapid enlargement, constitutional symptoms, atypical tonsillar appearance, ipsilateral cervical lymphadenopathy, and a history of previous malignant growths. In the absence of these risk factors, the likelihood of a malignant neoplasm is small.

Periodontal Surgery: Any surgical procedure used to treat periodontal disease or to modify the morphology of the periodontium. The bony crest on the lateral surface of the maxilla is termed the zygomaticoalveolar crest. Palatal tori may be present at the midline of the hard palate while smaller exostoses are frequently observed over the palatal roots of the molars (Clarke and Bueltman, 1971). The mandible is a horseshoe-shaped bone which is grossly characterized by the mental protuberance, body, and ramus. It contains paired foramina (F) per side (inferior alveolar F; mental F) which transmit neural/vascular structures, bearing the same names. Other important landmarks include the mylohyoid ridge, genial tubercles, temporal crests, alveolar processes, and external oblique ridges (Clarke and Bueltman, 1971). Vascular Supply the vascular supply of the periodontium originates from branches of the external carotid artery. The main branches which supply structures in the oral cavity are the lingual, facial, and maxillary arteries. The inferior alveolar and greater palatine arteries are branches of the maxillary artery (Clarke and Bueltman, 1971). The blood supply of the gingiva is derived primarily from supraperiosteal vessels which represent terminal afferent branches of the following arteries: 1) sublingual; 2) mental; 3) buccal; 4) facial; 5) greater palatine; 6) infraorbital; and 7) the posterior superior dental. These vessels anastomose with those supplying the alveolar bone and periodontal ligament. Prior to entering the apical foramina respective dental arteries (branches of superior or inferior alveolar dental artery) are the originating sites of the intraseptal arteries. A plexus of vessels with numerous venules (dento-gingival plexus) is located beneath the junctional epithelium; in health, capillary loops are not found in this plexus. In contrast, the subepithelial plexus of the free and attached gingiva manifest capillary loops (7 (im) which supply individual connective tissue papilla.
