The first stage provides adequate soft tissue coverage medicine definition effective 25mg meclizine, both extranasally through the forehead flap and intranasally with local mucosal flaps treatment xeroderma pigmentosum discount meclizine 25mg. Free mucosal flaps harvested from the buccal mucosa may be necessary to provide a physiologic intranasal covering and prevent cicatrization of the raw flap under the surface symptoms your period is coming purchase 25 mg meclizine with amex. Intranasal stents and bolsters are necessary to maintain nasal patency and function symptoms emphysema buy meclizine visa. Once adequate soft tissue is in place, cartilaginous struts and framework harvested from the nasal septum, conchal bowl and crestal regions can be undertaken. Overgrafting is usually necessary as cicatrization and retraction generally ensue over the next several months after graft placement. Final stage reconstruction involves soft tissue adjustments to the nasal base (dermabrasion or excision of scar), tip (thinning thickened transplanted forehead skin) and alar rim areas (selective thinning of cartilage or skin). Great care should be exercised to avoid compromise of the lining mucosa and nasal vestibular area. The major guiding principle is excision of the cancer with negative margins usually regarded as 5 mm or more of histologically normal tissue around the tumour for oral cavity squamous cell carcinomas. In order to achieve this, the surgeon will usually make his excision 1+ cm around the palpable defined margin of the cancer. In lesions less than one-third of the lip, the natural elasticity of the lip, especially in elderly patients, will allow primary closure. The lower lip is held tightly and compressed between finger and thumb by the assistant who everts the lip. The excision is continued with a needle tipped cautery through the obicularis muscle on both sides, taking care to identify the labial artery superiorly as the mucosal surface is approached. In oral squamous cell carcinoma in smokers and drinkers, pan-endoscopy is undertaken first. The incision is closed in layers with 4/0 vicryl to mucosa, 3/0 vicryl through muscle and 5/0 nylon to skin with the vermilion border suture being placed first. Actinic damage affects the whole lip and in actinic keratosis or multifocal dysplasia/superficially invasive cancer vermilionectomy is indicated. This procedure can be combined with any of the other excisional techniques described in this section. The entire vermilion from the wet line to the skin is marked out with a surgical marking pen. The lower lip is stretched between skin hooks placed in the commissures and starting at one end, an 11-blade is used to transfix the width of the vermilion. Using a sawing motion, the blade is advanced across the lip to excise the entire vemilion (Figure 4. The depth of excision will depend upon the depth of the lesion(s) being removed and local control of tumours with up to 3 mm maximum depth of invasion is reported. Closure is usually by an advancement flap of the labial mucosa which is mobilized with sharp scissors or fine mosquitoes dissecting submucosally in the layer between the mucosa and obicularis (Figure 4. This simple reconstruction may cause thinning of the vermilion and eversion of beard bristles. A variety of designs are available, but the bipedicled flap will resurface the entire vermillion (Figure 4. Two parallel incisions, approximately 1 cm apart, are made with a needle point cautery transversely across the dorsum of the tongue. The bases of the flap at the lateral sides of the tongue diverge to increase blood supply. The flap is passed forward and under the tongue tip and the tongue closed primarily. In the office for superficial lesions and dysplasias, vermilionectomy with the carbon dioxide laser is an alternative. The sutured incision should lie in the submental fold and the obicularis fibres maintain their natural orientation to maximize function. When cancers involve the commissure and up to half the lip, the author prefers the geometric design of the McGregor variation of the fan flap. The two other squares are raised as one large full thickness rectangle, the dotted line between B and C being purely for design purposes. The isthmus at the commissure, point X, must be carefully preserved as the pedicle with the superior labial artery is contained within this narrow strip of tissue. Square B is now rotated to reconstruct the lip and square C fills the defect from B (Figure 4. The resultant defect is closed by the natural laxity of the cheek in the line of the nasolabial fold (Figure 4. The vermilion is reconstructed by advancing the mucosa on the oral side of the flap. In lesions requiring two-thirds to total lip excision, there are a number of options. The tumour is excised as a rectangle and the flaps are designed as shown (Figure 4. The full thickness flaps marked X and Y from the cheeks will be advanced to reconstruct the lip.

Extensive bone grafting is recommended to create adequate bone volume for placement of endosseous implants to restore the severely resorbed or resected maxilla with a fixed prosthesis treatment quadriceps tendonitis order meclizine overnight delivery. Bone grafting procedures include onlay grafts medications given during dialysis cheap 25 mg meclizine with mastercard, inlay grafts into the floor of the maxillary antrum and Le Fort I maxillary osteotomy with advancement and downgrafting techniques symptoms ear infection purchase meclizine cheap online. Newly grafted bone has to remain load-free to allow consolidation and revascularization for four months natural pet medicine order meclizine 25mg visa. Staged bone graft techniques increase treatment time, which is tedious and socially unacceptable for the patient. Diagnostic radiology Radiological assessment for the zygomatic implant protocol is used to detect the presence of pathology within the maxillary sinuses and to evaluate the volume of bone available in the maxillary alveolus and zygomatic body. The zygomatic implant has provided the clinician with an alternative to grafting procedures in the reconstruction of the severely resorbed maxilla. Branemark originally designed the technique in 1989 and has a reported success rate of 97 per cent. This implant traverses the posterior maxillary alveolus and lateral sinus wall into the body of the zygoma. The restorative interface requires angular correction from the long axis to allow for appropriate tooth position. Occipito-mental views to assess the extent of the maxillary sinus and presence of sinus pathology. In oncology and trauma surgery, a threedimensional spiral reconstruction is useful. Optimal implant placement is dictated by the position of three distinct anatomical sites: 1 the position of the incisura between the zygomatic arch and the frontal process of the zygomatic bone (Figure 2. For optimal implant placement, the position of the incisura is fixed and provides the superior pivot point of the zygoma implant (Figure 2. Occasionally, the surgeon can place the exit point of the implant more medially towards the infero-lateral orbital margin and great care should be taken to avoid perforation into the infero-lateral aspect of the orbit. This puts the implant into an upright position and brings the restorative head into the first molar site instead of the second premolar site. The head of the implant in the maxillary alveolus is placed as close to the mid-alveolar position of the ridge as possible (Figure 2. A crestal incision is made extending from 1 cm in front of the maxillary tuberosity to the same position on the contralateral side. Periosteal elevation results in the exposure of the entire maxilla, around the base of the piriform rim, up to the inferior aspect of the infraorbital nerves and finally exposing the inferior aspect of the body of the zygoma bilaterally (Figure 2. A round bur is then used to create a lateral window in the superior-lateral aspect of the wall of the maxillary antrum, with sinus mucosa reflection. Using a round burr, the proposed point of entry of the fixture into the zygomatic bone is demarcated through the sinus window (Figure 2. Care should be taken not to perforate the bony orbit with subsequent disruption of the orbital contents (Figure 2. Final placement of the fixture is accomplished by ensuring proper angulation of the implant platform by placement of a guide pin into the implant and the fixture rotation to ensure optimal position (Figure 2. Standard protocol is two zygomatic implants placed posteriorly with four paranasal implants and a fixed porcelain fused to the titanium prosthesis (Figure 2. Treatment options include a unilateral sinus graft or the utilization of a hemi-zygomatic protocol with the placement of one standard endosseous fixture and a zygomatic in the posterior maxillary region (Figure 2. An autogenous bone graft can be avoided and is advantageous as the patient is saved the morbidity and possible complications of a bone graft. Restoration of standard zygomatic protocol with full cross arch permanent prosthesis (b). The surgical technique is as for standard zygomatic fixture placement and a more palatal mucosal incision is made to include an adequate band of attached mucosa (Figure 2. Care should be taken not to perforate into the inferolateral aspect of the orbit with the more anterior fixture and post-operative radiographs are obligatory. It is possible to immediately load these implants with a fixed hybrid acrylic strengthened prosthesis, which remains in place while healing takes place (Figure 2. This avoids a second procedure to expose the implants four months after placement. This has cost implications since hospital stay, theatre time and recovery time are all reduced, allowing the patient to be integrated back into society more quickly. After healing has taken place, the temporary prostheses are replaced with fixed porcelain fused to a titanium prosthesis (Figure 2. Zygoma, zygomatic implants and oncology reconstruction 123 (a) (b) (c) prosthesis in the left maxilla. The surgery is complex and involves sealing of the oral cavity from the nasal cavity, reestablishment of the paranasal sinuses and restoration of the facial contour. Dental rehabilitation is also a massive functional and aesthetic consideration that should be considered when planning the proposed reconstruction. Reconstruction depends on the extent of the resultant bony and soft tissue defect and obturation requires a working relationship between the surgical and prosthetic teams.

Progression of the disease continues to about 30 years of age treatment bladder infection buy meclizine toronto, and according to Sun and Streib treatment for pneumonia purchase meclizine online now, the course of the illness thereafter remains unchanged treatment 3 nail fungus generic meclizine 25 mg line. In paramyotonia congenita there is also In contrast myotonia of early onset symptoms xanax is prescribed for cheap meclizine 25 mg otc, but, again, it tends to be mild, involving mainly the orbicularis oculi, levator palpebrae, and tongue; the diagnosis of paramyotonia is seldom in doubt because of the worsening with continued activity and prominent cold-induced episodes of myotonia and paralysis. In patients with very large muscles, one must con sider not only myotonia congenita but also familial hyperdevelopment, hypothyroid myopathy, the Bruck-de Lange syndrome (congenital hypertrophy of muscles, mental retardation, and extrapyramidal movement dis order), Becker myotonia (see later), Duchenne dystrophy, and most of all, hypertrophic myopathy (hypertrophia musculorum vera); this last disease is of interest because the aberrant protein (myostatin) and gene defect have been characterized. Testicular atrophy, cardiac abnormality, frontal baldness, and cataracts-the features that characterize myotonic dystrophy-are conspicuously absent. The derivative disorders normokalemic periodic paralysis, acetazolamide responsive myotonia, myotonia fluctuans, and myotonia per manens are variants of hyperkalemic periodic paralysis. All of them are caused by mutations in the gene encoding the alpha subunit of the membrane-bound voltage-gated Hyperka lemic Periodic Pa ra lysis the essential features of this disease are episodic general ized weakness of fairly rapid onset and a rise in serum potassium during attacks. Weakness appearing after a period of rest that follows exercise is particularly charac teristic. This type of periodic paralysis was first described and distinguished from the more common (hypokalemic) form by Tyler and colleagues in 195 1. Five years later, Gamstorp described two additional families with the dis order and named it Tre atm e n t Quinine i s effective in reducing myotonia but i s now used infrequently because of the (low) risk of causing torsade de pointes. As fur ther examples were reported, it was noted that in many of them there were minor degrees of myotonia, which brought the condition into relation with paramyotonia congenita (see further on). Hyperkalemic periodic paraly sis is associated with a defect in the alpha subunit of the sodium channel gene (Fontaine et al, 1990). It is now appreciated that there are distinct variants of hyperka lernic periodic paralysis that are genetically distinct. All are associated with membrane hyperexcitability because of delays in sodium channel inactivation following mem brane depolarization, as discussed later. The cardiac antiarrhythmic drug tocainide (1,200 mg daily) has also proved effective, but it sometimes causes agranu locytosis and is no longer recommended. General ized Myotonia (Becker Disease) this is a second form of myotonia congenita, inherited as an autosomal recessive trait. Like the dominant Thomsen form, it is caused by an allelic mutation of the gene encoding the chloride ion channel of the muscle fiber membrane. The clinical features of the dominant and recessive types are similar except that myotonia in the recessive type does not become manifest until 10 to 14 years of age, or even later, and tends to be more severe in the dominantly inherited variety. There may be associated mild distal weakness and atrophy; this C l i n i c a l M a n ifestati o n s the pattern o f inheritance is autosomal dominant as noted, with an onset usually in infancy and childhood. Characteristically, attacks of weakness occur before break fast and later in the day, particularly when resting follow ing exercise. In the latter case, the weakness appears after trunk, arms, 20 to 30 min of becoming sedentary. The patient notes dif ficulty that begins in the legs, thighs, and lower back and spreads to the hands, forearms, and shoulders over min utes or more. According to Haass and colleagues, myotonia that is constantly present in a warm environment diminishes with repeated contrac tion, whereas myotonia induced by cold increases with repeated contraction (paradoxical myotonia). Like hyperkalemic periodic paralysis, paramyoto nia congenita is transmitted in an autosomal dominant manner and both diseases have been linked to the same gene late adolescence and the adult years, when the patient becomes more sedentary, the attacks may diminish and even cease entirely. In certain muscle groups, if myotonia coexists, it is difficult to separate the effects of weakness from those of myotonia. Indeed, when an attack of pare sis is prevented by continuous movement, firm, painful lumps may form in the calf muscles. Usually, however, the presence of myotonia can only be detected electromyo graphically. Some patients with repeated attacks may be left with a permanent weakness and wasting of the proxi mal limb muscles. During the attack of weakness serum K rises, often, but not always, up to 5 to 6 mmol /L. With increased urinary excre tion of K, the serum K falls and the attack terminates. La bo rato ry F i n d i n g s In both hyperkalemic periodic paralysis and paramyotonia congenita, the serum K is usually above the normal range during bouts of weakness, but paralysis has been observed at levels of have a critical level of serum K, which, if exceeded, will virtually alike in all clini In the paramyotonic form dis cussed below, the attacks are associated with paradoxical myotonia (myotonia induced by exercise and also by cold). Each patient appears to provocative test, undertaken under careful super be associated with weakness. The weakness typically has a latency of to term the periodic paralysis as potassium dependent. The test should never be undertaken in the presence of an attack of weak ness, or when there is reduced renal function, or in those with diabetes requiring insulin. In vitro studies of muscle from patients with cold induced stiffness and weakness have shown that as temperature is reduced, the muscle membrane is pro gressively depolarized to the point where the fibers are inexcitable (Lehmann-Horn et al, 1987). In patients with paramyotonia, but not in those with hyperkalemic periodic paralysis, Subramony and colleagues observed a diminution of the compound muscle action potential in response to the cooling of mus cle, largely settling the argument as to whether the two syndromes (hyperkalemic paralysis and paramyotonia) are the same or different. Some patients with paramyotonia, like those with certain other forms of periodic paralysis, may in later life slowly develop a myopathy that causes persistent weakness. In some cases this is sufficiently severe that it mimics the pattern of late-onset limb-girdle muscular dystrophy. However, in the case of paramyotonia there are relatively few histologic changes, primarily vacuoles in some of the muscle fibers and minimal evidence of myofiber degeneration. Normokalemic Periodic Paralysis sodic paralysis resembles the hyperkalemic form in prac tically all respects except that serum potassium does not increase out of the normal range, even during the most severe attacks.

A flat board should be advanced just in front of the dermatome to ensure a flat surface is presented to the blade. A slow even progression of the dermatome prevents folding of the skin ahead of the blade producing a more even cut. Meshing of the graft can increase the size of the graft by about 30 per cent but in most cases the meshing is merely to create small perforations to prevent haematoma formation. Topical cleaning prior to and after surgery may be helpful, but the routine use of antibiotics is not indicated. Meticulous haemostasis is needed to ensure good contact between the graft and the nutritional wound bed. Firm pressure to stabilize the graft and prevent a haematoma forming beneath the graft. Again, stab perforations or meshing of the graft helps to prevent haematoma formation. The donor site can be extremely painful and this must be anticipated and prevented. A commonly used technique is to apply an alginate dressing impregnated with long acting local anaesthetic, such as buvicaine, or the non-steroidal volterol in an i. It is essential to keep the wound under observation to check for haematoma formation or infection as the wound may need to be exposed and cleaned up. The skin can be harvested with a conventional hand held blade, but it is very difficult to get an even thickness. The standard traditional skin grafting knife has more or less been replaced by a powered dermatome. This produces a very even thickness graft, but more importantly the width of the graft can be more easily predicted. The success of the Resorbable materials are in theory highly desirable, since it avoids another procedure for the patient. Unfortunately, these materials have a number of problems: the resorption process is equivalent to a foreign body reaction, producing significant inflammation. The use of subcutaneous resorbable sutures may mask these problems somewhat (see Figures 3. The use of a resorbable material, such as vicryl rapide, has the shortest resorption time of around 14 days but is a textured material leading to more tissue reaction. For a successful outcome: Excessive tension will reduce blood supply and lead to dehiscence and infection. The only non-muscle flap with a true vascular pedicle is based on the greater palatine vessels, the rest are random pattern flaps. Unlike skin, the local anatomical variations of the mucosa do demand special attention. It is most important that attached mucosa is attached to the gingiva of the teeth. In some cases this is not possible and free full thickness attached mucosa, normally harvested from the palate, may have to be used. If, however, the patient is young or the defect is small and easily and quickly becomes re-vascularized, a free non-vascularized graft may be indicated. Dotted line denotes incision when no radical neck dissection is necessary and dashed line denotes incision if radical neck dissection if performed. This process takes time and it is essential that the graft is placed in a highly vascularized environment free from any infection. In practical terms, the graft in the mouth needs to be a sealed vascularized environment with good vascularized mucosa covering the graft. This may be to an orbital floor or nasal graft; secondary jaw reconstruction of small continuity defects, in which the fragments have been stabilized by bone plates. Again only small defects in patients with wellhealed soft tissues with excessive scarring will be successful; it has very little value because of the predictable poor outcome in reconstruction after oral cancer ablation. Site Cranium, outer cortical plate Rib with or without costal cartilage Indications and disadvantages Hard stable bone, scar normally hidden in the hair. With the cartilage in 30 per cent of cases harvested in young children it will continue to grow. Small risk of chest complications especially in the elderly, pneumothorax and chest infection. Can be painful In young females, the harvesting may, if too high, damage breast development Ilium anterior approach One of the commonest sites yields large volumes of bone (especially with the posterior approach), it has an unobtrusive scar. While it is very painful, unless a trephine is used, it has few significant side effects. Damage to the lateral cutaneous nerve of the thigh should be easy to avoid, but it does happen and is a significant problem. The posterior approach is much less frequently used as it is necessary to rotate the patient prevent synchronous surgery to the mouth and bone harvest Tibia this is a trephine approach which yields small volumes but ideal for alveolar defects. Little visible bone implantology where small defect, haematoma may produce swelling volumes of particulate Cortical bone scarification. It produces a bone are required good volume of particulate bone, ideal in implantology, but no value for continuity defects, unless very small Surgical technique 181 Common donor sites Clearly any part of the bony skeleton can be used, but in reality only a few are regularly used (see Table 3.
