While some other operations may claim difficult anatomical access, requisition of excessive physical strength, or significant operating time causing surgeon fatigue, the operation of rhinoplasty demands a thorough understanding of an art and science. Each case has its own challenges and requires a careful estimation of the deformity preoperatively, a clear understanding of the techniques available for correction, a proposed plan of action and sequence, and a meticulous, uncompromising execution of the surgical technique. Every surgical operation has a tendency to complications, and only the surgeon who does not operate has no complications. A knowledge of relevant complications and sequelae is essential to enlighten the patient so that an informed decision can be made, for reducing the incidence of such complications, for minimizing the gravity of an impending complication, and for treating a complication once it has occurred. Some complications of rhinoplasty relate to anesthesia and do not fall within the bounds of this discussion. Anaphylactic reactions to general and local anesthetics may well tax the knowledge and skill of the anesthesiologist, surgeon, and attending staff. Complications of rhinoplasty may be divided into 4 basic categories as follows:
ProblemA complication may be defined as an unexpected occurrence of an adverse medical or surgical condition requiring separate attention during or following an operation. While recognizing obvious medical and surgical complications should present no difficulty, finer aesthetic complications are harder to define and are based on value judgments related to the aesthetic sense of the surgeon and the body-image demands of the patient. A patient's body-image demands may be categorized as follows:
Aesthetic sense is difficult to define, and it is much harder to agree on results. Aesthetics depend on variables, including the current fashion taste, the media, the public relations industry, and cultural and ethnic differences. A practical approach to aesthetics in the nose begins with an accurate assessment. Frontal views define x-axis (width) and y-axis (height) deformities, lateral views define z-axis (depth/projection) and y-axis deformities, and basal views define x-axis and z-axis deformities. Based on these views, a 3-dimensional concept of the nose is made available for manipulation. The goal of rhinoplasty is to improve the existing harmony without causing functional impairment. FrequencyAccording to the literature, the complication rate for nasal surgery varies from 4-18.8%. In individual hands, this rate generally falls as surgical experience accumulates. Skin and associated soft tissue complications occur in up to 10% of cases. According to estimates, severe systemic or life-threatening complications occur in 1.7-5% of rhinoplasty cases. Intracranial complications are rare. ClinicalThe clinical manifestations of rhinoplasty complications may broadly be classified as follows:
COMPLICATIONSIntraoperative complicationsExcessive bleeding This may relate to a genetic or acquired coagulopathy. The former should be investigated before surgery. If it has not been investigated, urgent consultation with a hematologist at the time of surgery is advised. Acquired coagulopathy is usually drug induced, and aspirin is usually a culprit. This drug should be stopped at least 2 weeks before surgery. Primary fibrinolysis causing excessive bleeding during rhinoplasty has been reported. This disorder is due to an abnormal activation of the fibrinolytic system leading to rapid clot dissolution. Blood tests for fibrinogen, fibrinogen degradation products, and euglobulin lysis time aid in making the diagnosis. In one particular case, it was treated with aminocaproic acid to good response. Consultation with a hematologist is advised when excessive bleeding occurs. Management may involve use of blood products, epsilon aminocaproic acid, and tranexamic acid. These agents may also cause problems such as deep vein thrombosis and pulmonary embolism. Inadequate local hemostasis may cause excessive intraoperative bleeding, contributing to operative difficulty and increased operating time. Excessive intraoperative hemorrhage reportedly occurs in 0.3-1% of cases. Tears of mucoperichondrial flaps A patient and meticulous technique usually prevent this complication, but it is difficult to avoid in noses that have been traumatized or that have had previous operations. Unilateral tears usually heal without incident, but bilateral aligned tears of the septal mucous membrane may result in a septal perforation and accompanying symptoms. Suturing these bilateral tears at the time of surgery with an intervening cartilage graft is best. Opposing tears of the septum and lateral wall may lead to synechiae formation and nasal obstruction. Symptomatic synechiae may need subsequent release. Buttonholing of skin This complication can occur during undermining of skin, particularly over the dome region; it is best avoided by careful attention to technique. Buttonholing may lead to scarring. If buttonholing occurs, attempt accurate nontension suturing to minimize scarring. Further treatment may be necessary if a scar results. Cautery burns Complications of this nature may be related to mechanical failure or to surgical error. Exercise appropriate caution when using cautery. Depending on the situation, relevant measures must be instituted if a burn occurs. Skin necrosis may result in a scar. Collapse of bony pyramid Collapse of the bony pyramid may occur during removal of a bony hump with an osteotome, particularly when the patient has had previous nasal trauma or if the vomer or ethmoid have been weakened as a result of previous surgery. Rasping may be advisable in these circumstances. Rectification requires careful approximation of the segments and provision of adequate internal and external splint support during healing. Disarticulation of upper lateral cartilage This complication may occur during rasping. Bilateral disarticulation produces an inverted-V deformity, and unilateral disarticulation produces asymmetry in the middle third of the nose. Spreader grafts may improve airway symptoms and aesthetics. Osteotomy complications
Perinasal trauma During osteotomy, particularly in noses that have previously been traumatized, there is a tendency to recreate preexisting fractures. The proximity of the orbit and cranium renders these structures most susceptible to such occurrences. Malfunction can result directly or can manifest subsequent to infection. Orbital hemorrhage and orbital cellulitis threatening vision need immediate attention in consultation with an ophthalmologist. Nasolacrimal apparatus injuries also may occur, and persistent symptoms may require fistulization of the sac into the nasal cavity. Infraorbital nerve injury has been reported. Cranial complications are discussed below. Immediate postoperative complicationsAirway obstruction Postextubation aspiration of blood may cause laryngospasm. This may require treatment with a muscle relaxant and reintubation or positive pressure ventilation. Nasal packing or intranasal splint aspiration also may cause airway obstruction. When these are in place, they must be adequately secured. Anaphylaxis This is a distinct possibility when intraoperative antibiotic medication is used. Anaphylactic shock subsequent to bacitracin nasal packing has been reported, and latex anaphylaxis is well documented.1 Visual impairment Transient and permanent deterioration of vision has been described subsequent to local anesthetic and vasoconstrictor injection. This may relate to vasospasm or thromboembolism causing ophthalmic ischemia. If symptoms persist, relevant consultation is advised. Early postoperative complicationsHemorrhage Reported prevalence of hemorrhage varies from 2-4%. Attempt to localize the source of bleeding after appropriate vasoconstrictor application. Endoscopic cauterization of the offending vessel may be possible. The nose may require packing and antibiotic cover. Major artery ligation for persistent bleeding has been reported. Septal hematoma This may need daily aspiration until the return is free of blood. Some authors advocate a larger incision to aid drainage and subsequent packing for 48 hours. Antibiotic coverage is indicated to guard against formation of a septal abscess. Infection
Dehiscence of incisions Dehiscence of internal incisions usually goes unnoticed. Unless predicted to cause synechiae, this is usually not a problem, as these incisions will gradually heal. The transcolumellar incision must be attended to immediately, or a scar will form, contributing to a poor result. Persistent edema Initial edema and periorbital ecchymosis may last 10 days. Severity may be determined by difficult osteotomies, use of guarded instruments, long operating times, excessive nasal packing, postoperative vomiting, or raised blood pressure. Apart from avoidance of the foregoing, performance of the osteotomies just before application of the dressing, intraoperative intravenous dexamethasone, postoperative head elevation, cold compresses to the nose, and blood pressure monitoring can minimize edema. Persistent edema and numbness over the nasal tip region may occur following external rhinoplasty and may last several months. This is not a problem if the patient has been forewarned. Skin necrosis Excessive undermining, injudicious cautery use, and overzealous skin thinning may lead to skin necrosis. This may cause an impaired blood supply and infection. Similarly, a tight dressing may cause vascular impediment and skin necrosis. Debridement and secondary healing is encouraged if necrosis occurs. Later, local steroid injection, dermabrasion, laser modification, and/or flap reconstruction may be necessary to aid scar aesthetics. Skin necrosis may also result from dorsal augmentation, in which case removal of the augmenting material may be necessary. Sequestra formation Sequestration of bone or cartilage may occur with subsequent infection, extrusion, and attendant deformity (which may be aesthetic or functional). In such circumstances, the infection is first controlled with antibiotics and/or surgical debridement. Reconstructive measures may be necessary at a further stage. Cardiovascular insufficiency In the elderly and those with cardiac disease, nasal packing can lead to hypoxia and associated problems. Simultaneous oxygen therapy is advisable under these circumstances. Cerebrospinal fluid rhinorrhea The prevalence of this complication is not high.3 A history of previous trauma may provoke its occurrence, as may the presence of congenital osseous defects. Identification of beta-2 transferrin in the draining fluid constitutes a definitive diagnosis. Most leaks heal spontaneously. Persisting leaks need localization and repair by extracranial and/or intracranial techniques. Contact dermatitis The dressing may contribute to this complication in sensitive individuals. Initial treatment involves removal of the dressing and administration of indicated antihistamines and/or steroids. Nasal blockage Postoperative trauma with the resultant edema and swelling can cause transient nasal blockage. Reassurance is all that is needed initially. Persisting nasal blockage may be related to vasomotor rhinopathy or unmasked allergic rhinitis. Patients who fail to respond to medical measures may require surgical turbinate debulking if causative. Numbness and pain Transient numbness and pain behind the upper incisors may be attributable to neurapraxia of the nasopalatine nerve. Olfactory disturbances Transient hyposmia is expected following nasal surgery and is related to several factors, including edema, direct trauma to the neuroepithelium, and use of certain pharmacologic agents. Patients with past facial trauma may be predisposed to injury of the olfactory apparatus during osteotomy. Postoperative neurotrophic viral infection may indicate an operative cause. Psychogenic factors also may be responsible. Anosmia occurs in 1% of surgeries.4 Carotid-cavernous fistula This is a rare complication and may be related to past trauma.5 Disturbed pressure gradients in the sinus cause orbital pain, proptosis, ophthalmoplegia, visual impairment, and an audible bruit. These signs and symptoms suggest the diagnosis, which can be confirmed by angiography. Modern neuroradiological treatment involving transarterial detachable balloon embolization has a high success rate. Reassurance demand A small number of patients need the surgeon to repeatedly express that the nasal blockage will disappear, the smell and taste sensation will return, the teeth anesthesia will subside, and the tip projection and swelling will decrease in time. Early psychological complications Transient episodes of anxiety or depression are not uncommon and may last up to 6 weeks after the operation.6 Late postoperative complicationsScar hypertrophy This may detract from a good result following an external rhinoplasty. Skin loss from infection and necrosis is a disaster. Aim initial attempts at reducing the size of the scar with intralesional steroids. Further treatment could include dermabrasion, lasers, and/or surgical scar revision. Polly beak nasal deformity This deformity is characterized by absence of the supratip dip and may present in degrees. The cause usually lies in undercorrection of the cartilaginous dorsum and the superior septal angle region (hard polly beak), but it may result from excessive accumulation of soft tissue scarring or loss of tip support (soft polly beak). Correction may require reduction of the cartilaginous dorsum and the superior septal-angle cartilage region and/or excision of the soft tissue scarring and fixation of a columellar strut. Oleogranulomas or dorsal cysts occurring in the supratip region may cause a deformity similar to polly beak deformity. In difficult cases, a CT scan may be necessary to confirm the diagnosis. Synechiae formation Synechiae or adhesions follow the creation of opposing raw surfaces. This occurrence may or may not be symptomatic. Stenting may be attempted if this complication is predictable at surgery. Endoscopic excision and subsequent stenting may be used to treat symptomatic synechiae. Septal perforation The prevalence of this complication has been described as 3-24.5%. Surgical closure may be attempted with smaller symptomatic septal perforations. Various techniques are described, and various success rates are quoted. If all else fails, a septal button is always available. Nasal valve collapse Aggressive cephalic trim of the lower lateral cartilages may provoke this complication. Collapse may cause airway distress and is a source of patient discontent. Cartilage spreader grafts may prove useful for internal valve collapse. Alar batten grafts improve external valve collapse. Nasal stenosis This is a disaster when it occurs, and it may be related to circumscribed incisions with excessive lining removal. Stenosis causes airway obstruction and is a source of persistent discomfort. Reconstructive surgery may provide some relief. Bossa formation Bossae are protuberances that may arise in the region of the nasal tip. Their postoperative incidence is quoted at 2%. While bilateral symmetric occurrences may assume a pleasing appearance, bilateral asymmetric and unilateral bossae demand surgical attention. During operation, ensuring that the remnant lower lateral cartilages are of equal dimensions on both sides is important. Bossae usually occur in noses with preoperative asymmetry, use of destructive rhinoplasty techniques, thin skin, and excessive postoperative scarring. The triad of thin skin, strong cartilages, and bifidity also indicate the patient who is prone to the development of bossae. Tip graft movement may also contribute to bossa formation. Recurrent meningitis Recurrent attacks of meningitis may follow an inability to localize a covert fistula. Apart from treatment of the attacks, continue attempts to locate the leak. Oleogranuloma Unabsorbable fatty material used on nasal packing may provoke an inflammatory reaction (variously termed as oleogranuloma, lipogranuloma, paraffinoma, oil granuloma, sclerosing lipogranulomatosis, and myospherulosis).7 A CT scan excludes other causes for the deformity. Surgical excision of the tissue is indicated with an appropriate warning of possible recurrence. Dorsal cyst Nasal mucosa displaced into the subcutaneous tissues may lead to this rare complication. Endonasal removal may be possible. Skin entrapped subsequent to injury may lead to an implantation dermoid, necessitating surgical removal. Aesthetic surgical misjudgments Undercorrection or overcorrection of a preexisting deformity leads to either persistence of the deformity or to introduction of a new one. A new deformity may introduce a functional deficit. Some of these deformities are illusory, and correction only follows after an accurate diagnosis is made. Ideally, revision rhinoplasty should not be performed until at least 12 months after the initial operation. These deformities may occur singly or in combination and may relate as an x-axis (width), y-axis (height), or z-axis (depth) deformity/deformities in the various segments.
A revision rhinoplasty may be required in 5-15% of patients. Any attempt at correction must always be accompanied by a rider promising only improvement and warning that a further "touch-up" operation may be necessary. Persistent psychological complications Several contradictory studies are available. Some studies claim that most primary rhinoplasty patients are psychiatrically disturbed, with a preponderance of personality disorders. Other studies show prospective patients to be relatively free of psychopathology. Still other studies show postoperative diminution of anxiety, obsessiveness, hostility, and paranoia, accompanied by improved self-concept. Even patients at high risk for poor psychological outcome reportedly benefit from cosmetic surgery. Nevertheless, in some psychologically fragile individuals, preoperative equilibrium may be disrupted. Dental complications Interference with the neurovascular supply of the teeth during surgery can cause dental devitalization. A dentist may provide further assistance. Gustatory rhinorrhea Parasympathetic and sympathetic cross excitation as a result of misdirected regeneration of nerve fibers subsequent to the trauma of surgery may cause rhinorrhea during eating.8 The treatment of this condition is difficult, but antihistamines may help some patients. Human adjuvant disease This is an autoimmune disease caused by hypersensitization to implanted material.9 Those affected probably are genetically predisposed to such hypersensitivity. If implants are considered, it is wise to probe familial history. In some patients, symptoms may be alleviated by implant removal. If this fails, referral to a rheumatologist is in order. Lacrimal Fistula Aesthetic surgery has 4 possible outcomes: (1) a happy patient and a happy surgeon, (2) a happy patient and an unhappy surgeon, (3) an unhappy patient and a happy surgeon, and (4) an unhappy patient and an unhappy surgeon. While the unhappiness of the surgeon usually relates to self-perfection, the unhappiness of the patient has several reasons, some of which may be genuine. The surgeon must be able to carefully select patients preoperatively. This demands a thorough knowledge of the patient's psychosocial status. Even so, selection mistakes may be made, and the temperaments of the surgeon and staff may be tested. No surgical operation is devoid of complications. It behooves surgeons, particularly those performing appearance-altering surgery, to be aware and to be informed of possible complications, avoidance measures, and associated corrective techniques. Patients must be informed of all possible complications, so they can make the decision to undergo surgery after carefully considering all risks involved. The surgeon minimizes complications by carefully selecting patients (through consideration of their medical and psychosocial deficiencies), by having a thorough understanding of deformities and correction techniques, by developing a sense of empathy, and by recognizing his or her own limitations. FUTURE AND CONTROVERSIESAs understanding of the anatomical, physiological, and pathological factors involved in nasal function and aesthetics improves, rhinoplasty will continue to be refined, and the incidence of complications will continue to decline. Aesthetic trends dictated by society will continue to influence the operation. Implant material hopefully will become more patient-friendly and surgeon-friendly and will contribute significantly to volume-enhancement needs with fewer complications. Technological innovations are leading toward endoscopic rhinoplasty, and computer imaging may soon dictate to the surgeon exactly what procedure is necessary. MULTIMEDIA
