Patient presents with epistaxis (thin blood-stained nasal discharge) antibiotics for sinus infection ceftin quality colcout 0.5 mg, puffy eyelids and lips infection 24 discount colcout 0.5 mg on-line, fever antibiotics for uti for male order colcout with a visa, toxemia and cellulitis of nose and face. Maggots lead to destruction of nose and paranasal sinuses, soft tissue of face, palate (perforation) and even eyeball. Maggots, which are larvae of flies (Genus Chrysomya), can infest nose, nasopharynx and paranasal sinuses and cause extensive destruction. Foul smelling nasal discharge attracts flies, which lay their eggs (about 200) that hatch in to larvae within 24 hours and secondary infection follows. Topical liquid paraffin, diluted chloroform or ether and turpentine oil nasal drops: They are used to irritate and stupefy the maggots so they come out of the nose. Patient will have inability to close the mouth, bloodstained saliva from mouth, intense pain in the ipsilateral jaw, and anesthesia of chin or ipsilateral lower lip (laceration of the inferior alveolar nerve of mandibular division of trigeminal nerve). Cerebrospinal fluid rhinorrhea: endoscopic repair based on a combined diagnostic approach: Indian J Otolaryngol Head Neck Surg. Give up that hateful malice, that dog-like bickering and barking at one another, and take your stand on good purpose, right means, righteous courage, and be brave. The separation of nasal tumors from tumors of paranasal sinuses is difficult except in early stages. Endoscopy: Endoscopy of the nose provides not only the detailed examination but also facilitates an accurate biopsy. Limitations: Poor delineation in areas of dental filling, orbital floor and intracranial extension in isodense avascular lesions. Biopsy: Biopsy from the tumor presenting in nose or extending to oral cavity is usually taken with biting punch forceps under local anesthesia. Nose and Paranasal Sinuses Section 3 w Benign tumors are usually smooth, localized and covered with mucous membrane while malignant masses are usually friable, have a granular surface and tend to bleed easily. Osteogenic sarcoma, chondrosarcoma, rhabdomyosarcoma, angiosarcoma, malignant histiocytoma are rare sarcomas. Biopsy: Generous tissue sample is usually taken for biopsy because special stains and electron microscopy may be required. Treatment: Tumors are usually treated surgically and not with irradiation because- Most tumors are not radiosensitive. Expansion of soft and cystic mass after coughing or valsalva maneuver indicates intracranial connection or major venous connection. Aspiration cytology: It is helpful in cases of intra-antral tumor and tumors that cause proptosis and present along medial aspect of the orbit. Disfigurement of face due to the fullness on the right side of nose SquamouS PaPilloma this verrucous growth is similar to skin warts. PleomorPhic adeNoma this rare tumor, which usually arises from the nasal septum, needs wide surgical excision. NaSal dermoid There occurs widening of upper part of nasal septum with splaying of nasal bones and hypertelorism. Treatment: Wide removal (surgical resculpturing) provides good cosmetic and functional results. Capillary hemangioma: this bleeding polyp of the anteroinferior part of nasal septum is a soft, dark red and pedunculated/sessile tumor. Origin: these locally aggressive tumors arise from the odontogenic tissue and usually involve maxillary sinus. It presents as red or grey masses, which may be translucent, edematous or simulate nasal polyps. Section 3 w PlaSmacyToma Solitary plasmacytoma of nose without generalized osseous disease predominantly affects males over 40 years. Extracranial meningioma: It arises from ectopic arachnoid tissue and needs electron microscopy for identification. Industrial workers: Workers of hardwood furniture industry, nickel refining, leather work and mustard gas manufacturing have higher incidence of sinonasal cancer. Adenocarcinoma of the ethmoids and upper nasal cavity is more common in workers of furniture industry. Workers of nickel refining are more prone to develop squamous cell and anaplastic carcinoma. Geographical: Bantus of South Africa who use locally made snuff, which is rich in nickel and chromium, have higher incidence of sinonasal cancer.

The saphenous nerve and superior genicular artecy emerge through the roof of 1he adductor canal and cross the edge of the adductor magnus muscle to reach the cleft between the sartorius and gracilis muscles antibiotic resistance debate discount colcout 0.5 mg on line. Fascial connections between the adductor magnus tendon and the medial intermuscular septum anterior to it may require division to expose the anterior surface of the adductor hiatus antibiotic 250mg cheap colcout online american express. Care should be taken to preserve the highest genicular artery and the saphenous branch of the femoral nerve antibiotics for uti during first trimester buy 0.5 mg colcout mastercard. The artery is situated medial to the vein at this level and therefore is encountered first on opening the sheath. Grafts to the supmgeniculate popliteal artery are best brought through the adductor canal with a blunt tunneling instrument. Deep fascia MeclallntermusctJiar septum Cut end of adductor mag nus tendon Semimembranosus m. There is a fascial connection between the distal adductor tendon and the medial intramuscular septum that must be divided to obtain 1he exposure shown. Mobilization must be adequate for safe exposure and may be aided by the use of soft vessel tapes. The fascia lata is incised posterior to the junction of iliotibial tract and lateral intermuscular septum. An incision that is too anterior leads in to the vastus lateralis muscle in front ofthe lateral intermuscular septum. They are retracted posteriorly wi1h the muscles in the lateral approach to the vessels. I 465 the popliteal vein (which may be paired) is encomtered first in the vascular sheath. The preferred conduit is ipsilateral saphenous vein, which has superior longterm patency compared with prosthetic graft. A longitudinal incision is made approximately 1 em behind the posterior border of the tibia, extending a third of the way down the calf from the lower posterior edge of the medial tibial condyle. The great saphenous vein is found 1 to 2 em posterior to the medial border of Flg. Anterior perfOiating branches from the saphenous vein may require ligation to ensure safe retraction. The crural fascia is incised 1 em posterior to the tibia, and the fascial incision is extended proximally to the level of the semitendinosus tendon. The underlying medial head of the gastrocnemius muscle is retracted posteriorly, exposing the neurovascular bundle in the proximal aspect of the incision. More proximal exposure can be obtained by dividing the tendons of the semitendinosus, gracilis, and sartorius muscles. Exposure of the artery is facilitated by the use of vessel tapes to elevate the artery above the vein in to the incision. Because the tunnel is created blindly, the actual pathway through the musculature of the thigh can only be estimated. Care should be taken to ensure that the graft is brought between the heads of the gastrocnemius muscle at the level of the knee joint; grafts routed through this muscle tissue may be compressed during muscle co:nt:Iaction. A vertical incision is made over the fibular head and extended distally over the proximal third of the fibula. On deepening the incision, one notes the tendon ofthe biceps femoris muscle inserting on the superior aspect of the fibular head. The biceps tendon is divided, and the common peroneal nerve with its deep and superficial branches is carefully dissected and retracted anteriorly. The biceps tendon and fibular collateralligameut are divided to begin mobilization of the head of the fibula. The fibular shaft can then be transected with no shears and the bone removed from its bed. Tmnssection of the fibular shaft with rib shears is aided by elevation of the proximal fibula. To prevent kinking, grafts should be routed such that they cross the knee at the midpoint ofthe lateral femoral condyle. These disorders include popliteal entrapment syndrome, cystic adventitial disease, and traumatic intimal flaps:from posterior knee dislocations. An S-shaped incision is preferred to avoid the deforming scar contractures associated with simple vertical incisions across the posterior knee.

The placement of these muscles follows from the above considerations of actions and reference plane for abduction and adduction antibiotic resistance threats in the united states cdc discount colcout online visa. A dorsal interosseous muscle lies on either side of the third metacarpal infection of the brain purchase colcout us, since any movement of the third digit away from its plane of reference is abduction bacteria botulism order colcout 0.5 mg with mastercard. The other two dorsal interosseous muscles occupy the space between the first second metacarpals for the first dorsal muscle and between the fourth and fifth metacarpals for the fourth dorsal muscle. The bipennate dorsal interosseous muscles arise by two heads from the adjacent sides of the metacarpals between which they Extensor digitorum, extensor digiti minimi, and extensor indicis tendons (cut) Superficial branch of radial nerve Lateral antebrachial cutaneous nerve (terminal part of musculocutaneous nerve) Posterior (dorsal) view lie. The first dorsal interosseous muscle is considerably larger than the others; the radial artery also passes in to the palm between its heads. The smaller palmar interosseous muscles adduct the same digit from whose metacarpal bone they arise and thus take origin from the palmar surfaces of the second, fourth, and fifth metacarpals. The tendons of both the dorsal and the palmar interosseous muscles pass dorsal to the deep transverse metacarpal ligaments between the heads of the metacarpals, and they have two insertions. The first insertion is to the base of the proximal phalanx; it is concerned with the abduction-adduction function. All the interosseous muscles are innervated by the deep branch of the ulnar nerve. Free movement of the thumb is most important in the more precise activities of the hand. The flexor pollicis longus muscle flexes the thumb, and the extensor pollicis longus and extensor pollicis brevis muscles extend it. The abductor pollicis longus muscle is an accessory flexor of the wrist; it abducts and extends its metacarpal. The short muscles of the thumb provide flexion, abduction, adduction, and opposition. Abduction of the thumb carries it anteriorly out of the plane of the palm because of the rotated position of the first metacarpal, which directs its palmar surface medially. The opponens pollicis muscle acts solely on the metacarpal of the thumb, drawing the digit across the palm and rotating it medially. The components of opposition are abduction, flexion, and medial rotation, the tip of the thumb reaching contact with the pads of the other slightly flexed digits. The motor, or recurrent, branch of the median nerve innervates the three muscles involved. The abductor digiti minimi and the flexor digiti minimi brevis muscles produce their characteristic movements. The opponens digiti minimi muscle rotates the fifth metacarpal medially and deepens the hollow of the hand. The intrinsic muscles of the hand are palmar and are therefore innervated by either the median or the ulnar nerve. Specific sets of muscles of the thumb and little finger, respectively, occupy the thenar and hypothenar compartments. Each compartment contains an abductor, an opponens, and a flexor muscle for its specific digit (abductor pollicis brevis, flexor pollicis brevis, opponens pollicis, abductor digiti minimi, flexor digiti minimi brevis, and opponens digiti minimi muscles). The flexor retinaculum and the bones to which it attaches (the scaphoid and trapezium radially and the hamate and pisiform on the ulnar side) provide the sites of origin for these muscles. The insertions of comparable muscles on the two sides are also the same: the base of the proximal phalanx for the abductor and flexor muscles and the shaft of the metacarpal for the opponens muscles. The central compartment contains four slender lumbrical muscles associated with the flexor digitorum profundus tendon. The interosseous muscles located in the intervals between the metacarpals occupy, with the adductor pollicis muscle, a deeply placed interosseousadductor compartment that is bound by the dorsal and palmar interosseous fasciae. To complete these generalizations, the rule of nervous innervation may also be stated: the median nerve supplies the abductor pollicis brevis, opponens pollicis, flexor pollicis brevis, and the most radial two lumbrical muscles; the ulnar nerve supplies all the other intrinsic muscles of the hand. The adductor pollicis muscle has two heads of origin, separated by a gap through which the radial artery enters the palm. The oblique head arises from the capitate and from the bases of the second and third metacarpals. The two heads insert together by a tendon that ends in the ulnar side of the base of the proximal phalanx of the thumb.

Topical nasal decongestant: the solution of cocaine or xylocaine with adrenaline brings about vasoconstriction (shrinkage of mucous membrane) and local anesthesia and facilitates the proper nasal examination antibiotic resistance understanding and responding to an emerging crisis purchase colcout 0.5 mg without a prescription. Probing of an ulcer in the floor of nose can exclude or confirm its oral cavity communication antibiotics immune system order 0.5mg colcout fast delivery. Posture test: Drainage of purulent discharge from various sinuses depends upon the posture of patient antibiotic vs antibacterial cream buy 0.5 mg colcout fast delivery. Persistent snuffles indicate trauma and infection from difficult delivery and need swab for culture. Nasal obstruction: Infants do not know mouth breathing and severe or complete nasal obstruction (bilateral choanal atresia) can be life-threatening. Moderate nasal obstruction may interfere with feeding and baby becomes restless after a few sucks. Diagnosis is confirmed with contrast (radiopaque solution in to each nostril) X-ray under general anesthesia. Ammonia, which stimulates the fibers of trigeminal nerve, is not used for testing smell. The reflected light from the head mirror illuminates the area of nasopharynx and the examiner sees the reflected image of the postnasal space in the postnasal mirror. If the patient is quiet and relaxed, then usually soft palate does not contract and hide the view. The anterior group of sinuses (maxillary, frontal and anterior ethmoid) drains in middle meatus. Frontal sinus: Anterior and inferior walls above the medial part of eyebrow and above the medial canthus. Normally, a crescent of light in the inferior fornix and glow in the pupil, which are equally bright on either side can be seen. Injury to olfactory nerves and olfactory bulb: Fractures of anterior cranial fossa. Any lesion anywhere in the olfactory pathway (olfactory mucosa, olfactory nerves, olfactory bulbs and tract and the cortical center of olfaction) will affect smelling power of the person. Unilateral choanal atresia, which is usually asymptomatic, may be missed in children. Electro-olfactogram: Electrode, which is placed on the olfactory epithelium, records a slow, negative and monophasic potential in response to odorants. The time lag between the perception of sweet taste and appearance of blue dye in the pharynx is noted. Acoustic rhinometry: It is an easy, minimally invasive, accurate and expeditious method of measuring dimensions of nasal airway. The measurement of nasal airflow is a sort of an inverse measurement of nasal obstruction. The rhinometry measurement of airflow poorly correlates with subjective perception of nasal stuffiness and obstruction. Infectious: Bilateral vestibulitis, rhinosinusitis (infectious, allergic and others), nasal polyps, atrophic rhinitis, septal abscess and large choanal polyp. The reasons of external valve compromise includes rhinoplasty, aging and caudal septal dislocation or trauma. If there is subjective improvement in nasal airway, the test is positive, which indicates nasal valve compromise. Acoustic rhinometry: a study of transient and continuous noise techniques with nasal models. Minor abrasions and hair follicles are common sites of both acute and chronic infections. Treatment: Medical treatment includes warm compresses, analgesic and topical and systemic antibiotics. Predisposing factors: They are: Nasal discharge due to rhinitis or sinusitis or nasal allergy. Burst open and discharging pus DeformitieS of external noSe the appearance of the external nose is frequently the subject of concern. Treatment: Surgery consists of splitting of the nasal bones and removal of cyst along with its extension in the upper part of the nasal septum. For intranasal meningoencephalocele, see chapter Tumors of Nose, Paranasal Sinuses and Jaws. Treatment: Augmentation rhinoplasty, which fills the dorsum with cartilage, bone or a synthetic implant.
