"There can be malposition or a functional problem, and there's risk of infection or breakdown of the skin," he explains.

Canthoplasty refers to a plastic surgery of the medial and/or lateral canthus. This technique is common in cosmetic procedures, as well as procedures that address eyelid function or malposition. A canthotomy involves cutting the canthus, often performed to release excessive orbital pressure (i.e., from orbital hemorrhage or infection).

However a skin graft is esthetically inferior and will always look like a shiny, irregularly pigmented, mismatched piece of skin. Alternatively, secondary placement of a tissue expander in the forehead can be used to correct the eyebrow malposition and to excise the skin graft and primarily close the forehead defect.

Hyperlysinemia is an autosomal recessive metabolic disorder characterized by an abnormal increase of lysine in the blood, but appears to be benign. It is caused by mutations in AASS, which encodes α-aminoadipic semialdehyde synthase. Hyperlysinemia is associated with ectopia lentis (a displacement or malposition of the eye's crystalline lens) in humans.

Anterior lens luxation in a dog Anterior lens luxation with cataract formation in a cat Ectopia lentis is a displacement or malposition of the eye's crystalline lens from its normal location. A partial dislocation of a lens is termed lens subluxation or subluxated lens; a complete dislocation of a lens is termed lens luxation or luxated lens.

As a result of a large initial defect, the flap has to be larger and the bigger the forehead defect will be. When there is a large resultant forehead defect it logically lies closer to the eyebrow. That is why there is a significant risk of superior eyebrow malposition, especially if a horizontal or oblique oriented forehead flap is used. Then the solution is to close the remaining defect with a skin graft.

The complication rate associated with ureterostomy procedures is less than 5–10%. Risks during surgery include heart problems, pulmonary (lung) complications, development of blood clots (thrombosis), blocking of arteries (embolism), and injury to adjacent structures, such as bowel or vascular entities. Inadequate ureteral length may also be encountered, leading to ureteral kinking and subsequent obstruction. If plastic tubes need inserting, their malposition can lead to obstruction and eventual breakdown of the opening (anastomosis).

A cyanotic heart defect is any congenital heart defect (CHD) that occurs due to deoxygenated blood bypassing the lungs and entering the systemic circulation, or a mixture of oxygenated and unoxygenated blood entering the systemic circulation. It is caused by structural defects of the heart such as right-to-left or bidirectional shunting, malposition of the great arteries, or any condition which increases pulmonary vascular resistance. The result may be the development of collateral circulation.

Floppy eyelid syndrome is a disease whose most prominent features often include floppy upper eyelids that can be easily everted, as well as papillary conjunctivitis. It is often associated with patients with high body mass index and obstructive sleep apnea. Floppy eyelid syndrome is thought to revolve around the upregulation of elastin-degrading enzymes, as well as mechanical factors. These can cause instability of the eyelid scaffold, resulting in the malposition of the eyelid.

Sensor types which are observing the molten pool are restricted in their applicability range by the fact that molten pool size and arc radiation are dependent on geometrical factors, e.g. material density or composition (alloying constituents). The optical observation of the molten pool region determines changes of the molten pool contour. The deflection from a contour which is defined as “ideal” is interpreted as malposition or as a change of the process behaviour and is compensated subsequently.

Treatment may involve surgery to correct the malposition of the eyelid(s). Punctal plugs may be used to increase the amount of lubrication on the surface of the eyeball by blocking some of the tear-drainage ducts. Eye drops may also be used to provide additional lubrication or to stimulate the eyes to increase tear production. The condition is not widely understood; in one instance, a passenger was removed from a US Airways flight because of it.

Women who have undergone breast augmentation also are susceptible to breast ptosis; which incidence might be induced by the physical and mechanical stresses exerted by the breast implants upon the internal tissues and the skin envelope; such overstretching thins the skin and atrophies its elastic qualities. Statistically, breast augmentation and mastopexy are plastic surgery operations with low incidence rates of medical complications; yet, when performed as a combined breast-repair procedure (mastopexy–augmentation), the physiologic stresses upon the health of the woman increase the risks of incision-wound infection, breast-implant exposure, damage to the breast and nipple nerves leading to sensation changes, malposition of the nipple-areola complex, and malposition of the breast implant in the implant pocket. Therefore, a mastopexy–augmentation procedure features increased surgical complication rates, when compared to the lesser complication rates of breast augmentation and mastopexy as discrete surgical operations; likewise, the individual incidence rates of surgical revision and complications, when compared to the revision and complication rates for the combined mastopexy–augmentation procedure. Recent studies of a newer technique for simultaneous augmentation mastopexy (SAM) indicate that it is a safe surgical procedure with minimal medical complications.

Handicapping malocclusion assessment record (HMAR) was created by Salzmann JA in 1968. It was created to establish needs for treatment of handicapping malocclusion according to severity presented by magnitude of the score when assessing the malocclusion. The assessment can be made either directly from the oral cavity or from available casts. To make the assessment more accurate an additional record form is made for direct mouth assessment which allows the recording and scoring of mandibular function, facial asymmetry, lower lip malposition in relation to the maxillary incisor teeth and desirability of treatment.

One study's definition is a total range of motion (ROM) <90 degrees constitutes AF, another definition is flexion contracture >10 degrees, or inability to flex the knee >100 degrees. AF is a diagnosis of exclusion; before making a final diagnosis of arthrofibrosis, other causes of stiffness following knee replacement should be excluded (ex: infection, malposition of the implants, or mechanical block to motion). In the case of AF after total knee arthroplasty (TKA) management typically consists of attempt at aggressive physical therapy, and in the case that fails manipulation under anesthesia (MUA). The rates of MUA after TKA vary widely.

The term 'pachygyria' does not directly relate to a specific malformation but rather is used to generally describe physical characteristics of the brain in association with several neuronal migration disorders; most commonly disorders relating to varied degrees of lissencephaly. Lissencephaly is present in 1 of 85,470 births and the life span of those affected is short as only a few survive past the age of 20. Pachygyria is a condition identified by a type of cortical genetic malformation. Clinicians will subjectively determine the malformation based on the degree of malposition and the extent of thickened abnormal grey differentiation present.

Along with these general signs and side effects, patients can have trouble healing. Women who are pregnant should be warned about things such as pre-labor rupture of membranes, drop in blood pressure with anesthesia, precipitate birth (very fast active labor), malposition of bleeding, and more. New mothers with hEDS should pay extra attention to taking care of their new baby. Mothers may have trouble taking care of the baby because of the risk of dropping the baby due to weak connective tissue in arms and legs, falling, postpartum depression (more than the general population), and healing from the birthing process.

For growing subjects, symptoms can also be varied as different growth aspects of teeth including the vertical, sagittal and transverse growth are different in children and adolescents. Generally, symptoms are more severe for earlier occurrence of the disease. Most ankyloses occurring in children are trauma-induced, which can lead to malposition of the affected teeth as the major symptom. For moderate and severe conditions in growing subjects, symptoms such as functional impairment due to loss of occlusal contacts which results from the reduced vertical distance of the ankylosed teeth, and shift in dental midline associated with tipping of adjacent teeth towards the affected tooth, are likely to be developed.

Fetal malpresentations are irregular positions of the crown of the fetal head in relation to the mother's pelvis (the fetus is in an abnormal position). Some important ways to manage fetal malpresentation are making rapid evaluations of the condition of the women pertaining to vital signs as well as the heart rate of the fetus. If fetal heart rate is abnormal, and if membranes have ruptured and amniotic fluid is atypical, it is important for medical professionals to determine the presenting part of the fetus and the position of the fetal head. Possible delivery methods, if this is the case, are compound presentation, Vaginal breech delivery, or caesarean section for breech presentation depending upon the severity of the malposition.

In addition, the longer the leads have been implanted starting from a year or two, the more likely that they will have attachments to the patient's body at various places in the pathway from device to heart muscle, since the human body tends to incorporate foreign devices into tissue. In some cases, for a lead that has been inserted for a short amount of time, removal may involve simple traction to pull the lead from the body. Removal in other cases is typically done with a laser or cutting device which threads like a cannula with a cutting edge over the lead and is moved down the lead to remove any organic attachments with tiny cutting lasers or similar device. Pacemaker lead malposition in various locations has been described in the literature.

Umbilical cord prolapse, an obstetric emergency that imminently endangers the life of the fetus. Obstructed labor due to malposition and malpresentation of fetus In response to the recent growth in interest over unassisted childbirth, several national medical societies, including the Society of Obstetricians and Gynaecologists of Canada, the American College of Obstetricians and Gynecologists, and the Royal Australian and New Zealand College of Obstetricians and Gynaecologists, have issued strongly worded public statements warning against the practice. Professional midwives' associations, including the Royal College of Midwives and the American College of Nurse-Midwives also caution against UC. Unassisted childbirth has been linked to substantially elevated rates of both maternal and neonatal mortality. One of the few, and perhaps the only, formal investigation of the mortality rates associated with the practice was conducted by the Indiana State Board of Health in 1984, among members of a religious community in Indiana.

However, the cosmetic effects of surgery are not necessarily stable. For spinal fusion surgery on AIS cases, with instrumentation attached using pedicle screws, complication rates were reported in 2011 as transient neurological injuries between 0% to 1.5%, a pedicle fracture rate of 0.24%, screw malposition assessed by radiography at 1.5%, 6% when assessed by CT scans though these patients were asymptomatic not requiring screw revision, and screw loosening noted in 0.76% of patients. For surgery without fusion in growing children, substantial percentage of patients undergoing SHILLA technique experience loss of correction via crankshafting or adding-on (eg, distal migration). In addition, the need for osteotomies on the concave side has the potential of severe complications. For MAGEC rods, higher distraction magnitude resulted in the generation of higher distraction forces, and this in combination with off-axis loading (exemplified by “growth marks”) result in wear and breakage of MAGEC rod’s components.

Incision lines for blepharoplastyThe thorough pre-operative medical and surgical histories, and the physical examination of the patient's periorbital area (eyebrow-to-cheek-to-nose), determine if the patient can safely undergo a blepharoplasty procedure to feasibly resolve (correct or modify, or both) the functional and aesthetic indications presented by the patient. Sequentially, lower eyelid blepharoplasty can successfully address the anatomic matters of excess eyelid skin, slackness of the eye-muscles and of the orbital septum (palpebral ligament), excess orbital fat, malposition of the lower eyelid, and prominence of the nasojugal groove, where the orbit (eye socket) meets the slope of the nose. Concerning the upper eyelid, a blepharoplasty procedure can resolve the loss of peripheral vision, caused by the slackness of the upper- eyelid skin draping over the eyelashes; the outer and the upper portions of the field of vision of the patient are affected and cause him or her difficulty in performing mundane activities such as driving an automobile and reading a book.

In surgical praxis, the abdomen is the primary donor-site for harvesting the tissues to create the free flap, because that region of the woman's body usually contain's sufficient (redundant) adipocyte fat and skin -tissues that are biologically compatible and aesthetically adequate for the construction of a substitute breast. The secondary donor-sites for harvesting adipocyte and skin tissues to create a free flap are the regions of: (i) the gluteus maximus muscles, (ii) the medial thigh, (iii) the buttocks, and (iv) the waist of the woman's body. The clinical advantage of the free-flap breast reconstruction procedure is avoidance of the medical complications—infection, malposition of the breast implant(s), capsular contracture—which occasionally occur consequent to breast-reconstruction surgery procedures that emplace breast prostheses to the mastectomy wounds. In which cases, the correction of such medical complications might surgically require either the revision (rearrangement) or the explantation (removal) of the breast implants.
