Abstract
Thirty consecutive cases of midline anterior craniofacial procedures for the treatment of malignant neoplasms arising from the paranasal sinuses were reviewed. Posterior and lateral base craniofacial procedures were specifically excluded. This review compares the results, in terms of survival and major complication rate, between en bloc and piecemeal resections. The average follow-up was 4 years and 3 months. Sixteen patients were treated with an en bloc resection. The major complication rate was 31%. One-year survival rate was 94% for the en bloc resection group, 67% for patients with positive margins, and 100% for patients with clear margins. Three-year survival for en bloc resection dropped to 56, 33, and 67%, respectively. Fourteen patients were treated with piecemeal resections. The major complication rate was 21%. One-year survival rate was 83% for the piecemeal resection group, 60% for patients with positive margins, and 100% for patients with clear margins. Three-year survival dropped to 70, 60, and 80%, respectively. Although it is considered desirable to obtain an en bloc resection in some craniofacial procedures, we conclude that a piecemeal resection is a viable alternative in situations where an en bloc procedure is difficult to obtain safely.

Abstract
Large palatomaxillary and oromandibular defects have a dramatic impact on speech, deglutition, mastication, and cosmesis. Traditional methods of reconstruction, such as locoregional flaps, free bone grafts, alloplastic materials, and prosthetic devices, have difficulty providing meaningful aesthetic and functional reconstruction of these defects. This article discusses current concepts in the reconstruction of large composite palatomaxillary and oromandibular defects with an emphasis on the role of free tissue transfer, including the factors to be evaluated when choosing a method of reconstruction, indications for specific donor sites, and recent technical refinements.

Abstract
BACKGROUND The nasogastric tube syndrome is a potentially life-threatening complication of an indwelling nasogastric (NG) tube. The syndrome is thought to result from ulceration and infection of the posterior cricoid region with subsequent dysfunction of vocal cord abduction. This dysfunction may present as complete loss of vocal cord abduction manifested as serious airway compromise. Reports of this syndrome are infrequent, with only 29 cases published to date. METHODS Two additional cases of nasogastric tube syndrome diagnosed at the University of Iowa Hospitals and Clinics over a 2-year period are presented. A search of MEDLINE (1966 through February 1999), including review of those articles' references identified seven previous publications, including 29 case reports. These 29 cases are reviewed and the findings summarized. RESULTS Twenty-nine cases of NG tube syndrome are identified, with 16 of these occurring in the preantibiotic period. Including the two cases presented here, 15 contemporary patients are examined. Among these 15 cases, 10 required tracheostomy, on average 8.5 days after NG tube placement. CONCLUSION Although the fully manifested syndrome presents quite dramatically, we suspect that a clinical spectrum of severity exists with less severe cases going unrecognized. Consistent with previous reports, we found that direct visualization of the postcricoid region is required to rule out the diagnosis and recommend such action be taken whenever the diagnosis is suspected. Treatment should include establishment of a safe airway, removal of the tube whenever possible, antibiotic therapy, and antireflux therapy.

Abstract
OBJECTIVES To (1) compare the complications and functional outcome of primary closure vs split-thickness skin grafting of the fibula osteocutaneous flap donor site, (2) identify patient-mix or treatment factors related to donor site complications, and (3) address early detection and management of donor site complications. DESIGN Retrospective review and questionnaire study. SETTING Two university tertiary referral centers. PATIENTS Fifty-three patients (31 men and 22 women, ages 20 to 80 years) who underwent fibula osteocutaneous free tissue transfer between February 1992 and January 1997. MAIN OUTCOME MEASURES Minor complications; major complications; and postoperative function, including sensory and motor deficits, pain, swelling, temperature intolerance, and activities of daily living. RESULTS Four patients developed major wound complications (group 1), 11 patients developed minor wound complications (group 2), and 38 patients had no wound complications (group 3). The donor site was closed primarily in 26 patients and with a split-thickness skin graft in the remaining 27 patients. Major wound complications developed in 3 patients (12%) who underwent primary closure and 1 patient (4%) who underwent split-thickness skin grafting. Minor wound complications developed in 7 (27%) of the patients who underwent primary closure and 4 patients (15%) who underwent split-thickness skin grafting. Three patients who had major complications had residual sensory or motor deficits that resulted in impaired gait or alteration in their daily activities. Comparing all patients with complications (groups 1 and 2) to patients with no complications (group 3) demonstrated an increased incidence of donor site complications in heavy smokers (P<.05) and a strong trend toward higher donor site complications in patients who underwent primary closure (P =.10). Although trends were identified, no significant differences were found in age, comorbid illnesses, alcohol use, preoperative laboratory values, operating time, tourniquet time, or skin paddle width. CONCLUSIONS A variety of patient-mix and operative factors are likely related to the development of donor site wound complications. Width of the skin paddle alone is not a reliable criterion for determining the need to skin graft the donor site. Primary closure tended to result in a higher rate of both major and minor wound complications compared with split-thickness skin grafting. Primary closure of fibula donor site defects should be undertaken if this can be accomplished with no tension along the suture line. If tension at the suture line is present, a skin graft should be strongly considered to minimize the possibility of a wound complication. Arch Otolaryngol Head Neck Surg. 2000;126:1467-1472

Abstract
OBJECTIVES In lymph nodes harboring metastases the reticuloendothelial system is replaced by tumor cells and does not concentrate iron particles. This study assesses the value of contrast magnetic resonance imaging (MRI) using ultrasmall superparamagnetic iron oxide particles (Combidex, Advanced Magnetics, Inc., Cambridge, MA) to characterize and stage neck nodes. STUDY DESIGN Prospective analysis of neck imaging by Combidex MRI, with correlation from pathological assessment of resected lymph nodes. METHODS Nine patients underwent MRI and subsequent bilateral neck dissections (three), unilateral neck dissections (five) or fine-needle aspiration (one). Each case was evaluated for the number, location, MRI characteristics, and pathological assessment of lymph nodes. RESULTS Forty-nine separate nodal levels were evaluated with both Combidex MRI and pathological assessment. The presence of metastatic nodal involvement among 45 levels was correctly assessed by the Combidex MRI (three false-negative results, one false-positive result; sensitivity, 84%; specificity, 97%). Analysis was possible for 101 of the individual lymph nodes identified by MRI that could be correlated with individual nodes pathologically examined. Combidex MRI assessment was correct for 99 nodes (one-false positive result, one false-negative result; sensitivity, 95%, specificity, 99%). Standard MRI interpretation without Combidex identified that 12 of 18 nodes (67%) that were greater than or equal to 10 mm (greatest dimension) contained tumor, whereas 9 of 83 nodes (ll%) that were less than 10 mm contained tumor. CONCLUSIONS Combidex MRI provides functional information to characterize lymph nodes in the clinical staging of squamous cell carcinoma of the head and neck. The inability of MRI to identify small lymph nodes restricts the usefulness of this technique.

Abstract
BACKGROUND The creation of osseous defects in the upper and lower jaws in children is an uncommon occurrence. It is therefore likely that a head and neck reconstructive surgeon will accumulate only limited experience in restoring such defects. We have reviewed 7 pediatric bone-containing microvascular free flap reconstructions in 6 patients for reconstruction of the upper or lower jaws. Three patients were available for long-term follow-up to evaluate the effect of osseous free flap reconstruction on function and growth and development of the donor site. DESIGN Retrospective review. SETTING Academic tertiary referral center for otolaryngology. PATIENTS AND METHODS Six pediatric patients ranging in age from 8 to 16 years underwent 2 fibular, 4 scapular, and 1 iliac free flap procedure for restoration of 2 maxillary and 5 mandibular defects from 1992 to 1997. Three of the 6 patients were available for long-term follow-up to assess the postoperative donor site function in an effort to determine the effect of this surgery on long-term donor site morbidity and development. RESULTS Two patients were lost to follow-up, and 1 died secondary to complications related to distant metastatic disease. Three of 6 patients were observed for 2 years 6 months, 4 years, and 4 years 2 months, respectively. Two of the 3 patients who were observed long term have undergone full dental rehabilitation and currently maintain a regular diet and deny pain with mastication or deglutition. One patient did not require dental rehabilitation. All 3 patients demonstrate gross facial symmetry and normal dental occlusion. Assessment of the fibular donor site demonstrated normal limb length and circumference. The patients denied pain or restriction to recreational activity. Scapular donor sites demonstrated normal range of motion, strength, and shoulder stability. CONCLUSIONS Free flap reconstruction of the pediatric maxilla and mandible requires harvesting bone from actively growing donor sites. We have found no evidence of functional deficit after bone harvest from the fibular or scapular donor sites. Patients demonstrate normal growth at the donor sites, and symmetry of the mandible and maxilla is preserved.

Abstract
BACKGROUND The purpose of this study was to assess the relative importance on patients' lives of multiple outcomes resulting from the management of head and neck cancer (HNC). METHODS HNC patients filled out a disease-specific quality of life (QOL) survey covering 5 domains (speech, eating, aesthetics, pain/discomfort, and social/role functioning). Logistic regression was used to determine which of these domains best predicted the patients' response to a single, overall QOL assessment. RESULTS In univariate analyses, all 5 domains were significantly correlated to QOL (p<.0001), with correlation coefficients ranging from.48 for eating to.64 for social/role functioning. Logistic regression indicated that speech and eating best predicted QOL (R(2) =.4647), with odds-ratios of 2. 96 for speech and 2.49 for eating. CONCLUSIONS These data demonstrated that, for this group of patients, speech has the most impact on well-being, whereas eating has a substantial, unrelated influence. This is important information in counseling patients about treatment plans that have different levels of impairment.

Abstract
OBJECTIVES To examine the relationship of various pretreatment case-mix characteristics and treatment modalities with medical charges incurred during diagnosis, treatment, and 2-year follow-up for patients with laryngeal cancer. DESIGN Retrospective chart review and billing record analysis. METHODS The charts and billing records of patients diagnosed with laryngeal cancer at the University of Iowa Hospitals and Clinics (UIHC) between January 1, 1991 and December 31, 1994 were reviewed. The independent variables included various pretreatment patient-mix and tumor characteristics (age, AJCC TNM clinical stage, smoking history, ASA class, and comorbidity as defined by Kaplan-Feinstein grade) as well as type of treatment. The dependent variables included total physician, office, and university hospital-based charges incurred during the pretreatment evaluation and 0- to 3-, 3- to 12, and 12- to 24-month billing periods after the initiation of cancer-directed therapy. Total 1-year and 2-year charges were also evaluated. Univariate and multivariate analyses were used to investigate the relationships between dependent and independent variables and to develop models predictive of management charges during the individual and total billing periods. RESULTS Pretreatment charges showed no significant associations (P < .05) with any of the independent variables. Multiple regression analyses indicated that comorbidity, stage, and initial treatment modality were significant variables in one or more of the models predicting charges incurred during the 0- to 3-month, 3- to 12-month, total 1-year, and total 2-year billing periods. The models yielded R2 values for the total 1- and 2-year billing periods of 0.5246 and 0.5055, respectively. CONCLUSIONS This work supports continued study of measures that may result in earlier detection of laryngeal cancer as a potential means of reducing management charges. These results also indicate that a more accurate method of stratifying the disease severity of laryngeal cancer patients for reimbursement purposes would include measurements of the severity of the index disease as well as comorbid diseases.

Abstract
BACKGROUND To employ patient-reported speech outcome data collected on head and neck cancer (HNC) surveys, there is a need to determine (1) the relationship of patient ratings to speech language pathologist (SLP) ratings and (2) whether patients' attitudes toward their speech are an important element of speech measurements. METHODS Associations were analyzed between (1) patients' ratings of speech function on surveys and equivalent SLP ratings and (2) patients' ratings of speech function and their satisfaction with speech function. RESULTS Patient-reported survey ratings were significantly associated with comparable SLP ratings. The associations were stronger for intelligibility than for voice quality. Patients' functional and attitudinal ratings were also significantly associated. The associations were relatively strong for composite speech items and intelligibility and moderate for voice quality. CONCLUSIONS Patient-reported speech outcomes can be interpreted as being fairly equivalent to SLP evaluations. Attitudinal ratings appear to contribute an important aspect of the patients' perspective, with substantially different variances between function and attitude.

Abstract
BACKGROUND Neutropenia and neutrophil dysfunction, in association with a variety of diseases, has been shown to play a role in poor wound healing. Wound breakdown with fistula formation in patients undergoing total laryngectomy results in significant morbidity and increased hospital stay. Although malnutrition, prior radiation, diabetes, and other diseases are recognized as factors predisposing patients with head and neck cancer to developing fistulas, neutrophil dysfunction should also be considered. Granulocyte colony stimulating factor (G-CSF) has been used successfully to treat neutropenia and neutrophil dysfunction. METHODS This study was conducted as a case report. RESULTS We present the first report of a neutropenic head and neck cancer patient with a persistent wound of 6 months' duration who showed dramatic improvement after treatment with G-CSF. CONCLUSION We conclude that G-CSF may represent a useful adjunct in patients with persistent wound healing problems and neutropenia despite adequate treatment by conventional means. Further clinical experience with G-CSF in patients with delayed healing is indicated.

Abstract
BACKGROUND Cervical lymphadenectomy to remove metastatic disease in level II encompasses lymph nodes associated with the upper third of the internal jugular vein and the adjacent spinal accessory nerve (SAN). Conservative neck dissection (ND) preserves these structures but requires manipulation of the SAN to remove tissue located in the posterosuperior aspect of level II. Limiting the dissection to the nodal group anterior to the SAN may reduce operating time and limit injury to it without compromising the removal of lymph nodes at risk for involvement with cancer. METHODS Seventy-one patients with squamous cell carcinoma of the head and neck treated with cervical lymphadenectomy at two separate institutions were prospectively evaluated. One hundred two neck dissection specimens were histologically analyzed for number of lymph nodes present and number involved with cancer. At the time of surgery, level II was separated into the supraspinal accessory nerve component (IIa) and the component anterior to the SAN (IIb). Nodal involvement in level II was analyzed according to characteristics of the cancer at the primary site as well as nodal involvement of other levels. RESULTS Neck dissections were most commonly done for cancer of the oral cavity (n = 33), followed in frequency by the larynx (n = 17), oropharynx (n = 7), skin of face (n = 4), unknown primary (n = 4), and other sites (n = 6). Eighty NDs were selective and 22 were either radical or modified radical NDs. Pathologic staging of the neck specimen was most commonly N0 (n = 61), followed in frequency by N1 (n= 17), N2 (n= 11), and N3 (n= 11). Data were unclear for two specimens. Level IIb contained an average of 6.9 nodes and the IIa component contained an average of 4.2 nodes. Level II contained metastatic disease in 31 of 39 node positive specimens (79%). Level IIa was involved with cancer in four cases, all of which were preoperatively staged N2 or greater. CONCLUSIONS The additional time required and morbidity associated with dissection of the supraspinal accessory nerve component of level II may not be necessary when performing elective ND. More research with larger numbers of patients, long-term follow-up, and meticulous tissue analysis is needed to permit conclusions as to where to draw the line in determining extent of cervical lymphadenectomy.

Abstract
Parotitis complicated by parotid abscess remains a potentially life-threatening problem. Conventional surgical treatment involves incising the parotid parenchyma in the direction of the facial nerve until the abscess is located and evacuated. Intra-operative ultrasound greatly assists in localizing the abscess and in ensuring its complete drainage. Expeditious and exact localization of the abscess reduces operative time. Equally importantly, ultrasound-assisted drainage reduces surgical dissection and the potential for facial nerve damage.

Abstract
BACKGROUND This study investigated the assignment of preference values to health states which may follow head and neck cancer (HNC) treatment. Preference values for these health states were provided by HNC patients, HNC health-care providers, and a group of college students representing individuals with little knowledge of HNC. METHODS A time trade-off technique was used by participants to assign preference values to four health states in the domains of appearance, eating, speech, breathing, pain, and work/social functioning. RESULTS Patients' and health-care professionals' rank-ordered preference value scores for health states in appearance, breathing, eating, and speech were not significantly different (p < .05). These two groups differed significantly in ranking four of the eight pain and work/social functioning health states. Patients and students differed significantly in ranking 21 of the 24 health states (p < .05). CONCLUSIONS Health-care professionals and patients had very similar perspectives regarding health states in the HNC-specific domains, indicating that these professionals appear to be a legitimate proxy for patients' attitudes in these domains. Healthcare professionals placed a significantly greater value on avoiding both pain and social confinement than did patients. Students, representing individuals naive regarding HNC, differed from patients and health-care professionals in their rankings of these health-state outcomes.

Abstract
BACKGROUND The National Cancer Data Base (NCDB), a large sample of cancer cases accrued from hospital-based cancer registries, is sponsored by the Commission on Cancer of the American College of Surgeons and the American Cancer Society. The NCDB permits a detailed analysis of case-mix, treatment, and outcome variables. OBJECTIVE To provide an overview of the contemporary status of the subset of patients with head and neck cancer in the United States. METHODS The NCDB, which obtains data from US as well as Canadian and Puerto Rican hospitals, accrued 4 583 455 cases of cancer between 1985 and 1994. Of these cases, 301350 (6.6%) originated in the head and neck. We address 295022 cases of head and neck cancer limited to the 50 United States and District of Columbia. Cases were segregated into an earlier group (1985-1989) to permit 5-year follow-up and into a later group (1990-1994) to analyze a more contemporary group. Comparison between both periods permits identification of trends. RESULTS The largest proportion of cases arose in the larynx (20.9%) and oral cavity, including lip (17.6%) and thyroid gland (15.8%). Squamous cell carcinoma (55.8%) was the most common histological finding, followed by adenocarcinoma (19.4%) and lymphoma (15.1%). Income level (low), race (African American), and tumor grade (poorly differentiated) were most notably associated with advanced stage. Treatment was most commonly surgery alone (32.4%), combined surgery with irradiation (25.0%), and irradiation alone (18.9%). Overall 5-year, disease-specific survival was 64.0%. Cancer of the lip demonstrated the best survival (91.1%) and cancer of the hypopharynx the worst survival (31.4%). CONCLUSIONS This NCDB analysis of cancer of the head and neck provides a contemporary overview of head and neck cancer in the United States. It also serves to introduce a series of NCDB articles that address specific anatomical sites and histological types through separate, detailed analysis.

Abstract
Impacted fractures of the lateral orbital wall are a type of orbital blow-in fracture that may be accompanied by decreased visual acuity and ocular motility limitations. Eleven patients who suffered this injury triad were retrospectively reviewed to determine the nature of the ophthalmologic injuries and the effect of fracture reduction on recovery of ophthalmologic functions. Two patients with decreased visual acuity owing to trauma to the globe recovered to subjective pretrauma levels following surgery. Nine patients were thought to have a traumatic optic neuropathy with varying degrees of visual loss. Patients with an injury to the intraorbital portion of the optic nerve and a presurgical visual acuity of 20/400 or better recovered to subjective pretrauma levels. Those with visual acuity of less than 20/400 or an injury to the intracanalicular portion of the nerve had responses ranging from no improvement to objective improvement with large field defects. Ocular motility improved in all patients, many in the immediate postsurgical period consistent with removal of a mechanical restriction. No patients had worsening of ophthalmologic deficits as a result of manipulation of fracture fragments. Our experience suggests that early surgical intervention facilitates recovery of vision and eye movement. The traumatic optic neuropathy that accompanies this fracture is distinct from the indirect type of optic nerve injury that may respond to steroids, and the ophthalmoplegia is distinct from the usual traumatic superior orbital fissure syndrome that resolves spontaneously. An understanding of the impacted lateral orbital wall fracture and its ophthalmologic implications is essential for any surgeon who desires to manage craniomaxillofacial injuries.

Abstract
BACKGROUND Tonsillectomy in adults (age 18 years and older) is performed for a variety of conditions. The palatine tonsils may harbor carcinoma or lymphoma, and this potentially unanticipated finding may follow routine tonsillectomy in the adult. The ability to preoperatively identify adult tonsillectomy patients at increased risk for tonsillar malignancy could sensitize the clinician to this possibility and the potential need for expedited rather than routine tonsillectomy scheduling. METHODS A retrospective review of 476 consecutive adult patients who underwent tonsillectomy during the last 10 years at the University of Iowa Hospitals and Clinics was undertaken. Proposed risk factors for tonsillar malignancy included a prior history of head and neck cancer, tonsillar asymmetry, palpable firmness or visible lesion in the tonsil, neck mass, unexplained weight loss, and unexplained constitutional symptoms. These risk factors were correlated with the pathologic diagnosis in the reviewed cases. RESULTS Of these 476 patients, 25 had malignant tonsil pathology. No patient without risk factors was found to have malignancy on pathologic evaluation of the tonsils. Of the 25 patients with malignant tonsillar pathology, 23 had two or more risk factors, and 2 patients had one risk factor. Tonsillar asymmetry, found in 20 of the 25 cases, was the risk factor most frequently associated with malignant pathology. CONCLUSIONS These results indicate that the presence of certain preoperatively identifiable risk factors are associated with the pathologic finding of malignancy in adult tonsillectomy specimens. Based on these criteria, a model which is predictive of the presence of tonsil malignancy may be constructed.

Abstract
OBJECTIVE Postoperative deep venous thrombosis and pulmonary embolus are major causes of morbidity and mortality in patients undergoing surgical procedures. In contrast to other surgical fields, the incidence of these life-threatening conditions has not been studied in our specialty. The purposes of this study were to elucidate the incidence of deep venous thrombosis and pulmonary embolus in patients after otolaryngologic operations and to identify specific risk factors that may contribute to the development of these conditions. METHODS A retrospective analysis was done of 12,805 total operations on adults done by the Department of Otolaryngology at our institution from January 1987 to December 1994 to determine the number of patients in whom postoperative deep venous thrombosis and pulmonary embolus developed. Patients in whom a postoperative thromboembolic event developed after an otolaryngologic surgical procedure were identified by the medical records department with use of an abstracting database. This search cross-referenced disease-specific codes for otolaryngologic procedures with the codes for deep venous thrombosis and pulmonary embolus to identify the 34 patients in this report. Results (rounded to the nearest decimal point) were then categorized according to the different subspecialties within otolaryngology, and appropriate statistical analysis tests were performed on the resulting data. RESULTS Thirty-four patients with postoperative deep vein thrombosis were identified during the study period, for an overall incidence of 0.3%. Of these 34 patients, 24 also had a pulmonary embolus for an overall incidence of 0.2%. The incidence of deep venous thrombosis (and pulmonary embolus) in the subspecialties was as follows: head and neck surgery, 0.6% (0.4%); otology/neurotology, 0.3% (0.2%); head and neck trauma and plastic surgery, 0.1% (0.1%); and general otolaryngology, 0.1% (0.04%). Only the patient's age and the presence or absence of pneumatic compression devices were identified as independent risk factors for the development of a thromboembolic event. CONCLUSIONS Postoperative pulmonary embolus is a rare occurrence in the field of otolaryngology-head and neck surgery. When it does occur, it causes significant morbidity and increases the cost of care for that patient. We discuss our approach to categorizing patients into low-, intermediate-, and high-risk groups, as well as prophylaxis against pulmonary embolus.

Abstract
PURPOSE This pilot study evaluated potential relationships between dental status and various sociodemographic variables in the age group segment of the United States population at greatest risk for the disruption of dental function due to treatment of an oral cavity cancer. METHODS The Dental Health Supplement of the 1989 National Health Interview Survey was used to evaluate the self-reported status of natural dentition and prior dental rehabilitation among the population of persons 45 years or older. RESULTS Sociodemographic variables, which showed a significant association with status of natural dentition, were level of income and occupation at lower income levels (p < 0.05). Increased levels of prior dental rehabilitation were significantly associated with lower age, female gender, increased level of income, and occupation (p < 0.05). Occupations that required social interaction had the highest levels of both status of natural dentition and prior dental rehabilitation (p < 0.05). CONCLUSIONS Overall dental status after treatment of oral cancer may be related to the occupational status of many persons. Sociodemographic factors that influence the dental rehabilitation needs of individual patients after treatment of an oral cancer should be considered in policy decisions affecting accessibility of dental rehabilitative care. A follow-up, survey study that would further define the identified relationships between a person's demographic status and dental rehabilitation needs is recommended.

Abstract
The objectives of this study were to investigate potential relationships between pretreatment patient-mix characteristics, treatment modalities, and costs generated during the pretreatment work-up, treatment, and 1-year follow-up periods for patients with oral cavity cancer (OCC). Another objective was to identify potential areas for cost reduction and improved resource allocation in the management of OCC patients. Using a retrospective cohort of 73 patients with OCC, pretreatment patient-mix characteristics and treatment modalities were evaluated in relation to university-based charges incurred during the pretreatment evaluation, treatment, and 1-year follow-up periods. Simple regression and stepwise multiple regression analyses were used to develop predictive models for cost based on independent variables, including age, AJCC TNM clinical stage, smoking history, American Society of Anesthesiologists (ASA) class, comorbidity as defined by the Kaplan-Feinstein grade and treatment modality. The dependent measurements included all physician, office, and hospital charges incurred at the University of Iowa Hospitals and Clinics during the pretreatment evaluation, treatment, and follow-up periods, as well as the total pretreatment through 1-year follow-up management costs. Independent variables that were identified as being significantly associated with treatment costs included T classification, N classification, TNM stage, unimodality versus multimodality treatment, and the Kaplan-Feinstein comorbidity grade. Age, smoking status, and ASA class were not significantly associated with costs. The majority of the OCC management costs were incurred during the treatment period. The most substantial decreases in management costs for OCC will be realized through measures that allow identification and treatment of disease at an early stage, in which single-modality treatment may effectively be used. Resource allocation for OCC should support the investigation of measures through which the diagnosis and treatment of OCC at the earliest possible stage is facilitated. The presence of comorbid illness is a significant component in the determination of management costs for OCC and should be included in analyses of resource allocation for OCC. The singular diagnosis of OCC encompasses a wide range of patient illness severity, and diagnosis-related reimbursement schemes for OCC treatment should optimally differentiate between early and advanced stage disease.

Abstract
BACKGROUND Mandibular reconstruction with functional dental rehabilitation using a free tissue transfer bone flap as the substrate for osseointegrated implant-borne or implant-retained dental prostheses is well described. Similar use of these techniques in maxillary dental rehabilitation is less frequent and has received less attention in the literature. However, in selected cases of extensive composite defects of the maxilla, free tissue transfer reconstruction of the maxillary arch and the use of implant-borne or implant-retained dental prostheses is the only satisfactory method of achieving functional dental rehabilitation. METHODS Three cases of maxillary reconstruction and dental rehabilitation using free tissue transfer with implant-borne or implant-retained prostheses are presented. Patient selection, reconstructive technique, and the biomechanical considerations in maxillary dental rehabilitation of large palatomaxillary defects are presented. RESULTS The patients in this report were restored to full maxillary dental functioning. One implant of 17 implants placed in free flap bone was lost due to failure of osseointegration; 94% of the implants placed are stable an average of 18 months after dental rehabilitation was complete. CONCLUSIONS In selected patients with extensive palatomaxillary defects due to ablative surgery or trauma, the use of free tissue transfer and osseointegrated implant-borne or implant-retained dentures may be the only method possible to restore maxillary dental function. Dental rehabilitation of large maxillary defects presents a number of biomechanical challenges which must be clearly understood and overcome to achieve a long-term, functional dental rehabilitation.

Abstract
BACKGROUND It is a common perception that the overall health of patients with head and neck cancer (HNC) is likely to be poor compared with the general population. This project was undertaken to investigate the pre- and post-treatment, global health status of HNC patients in comparison with age-matched, U.S. population norms using a self-administered general health status survey. METHODS Between July 1, 1993, and May 1, 1996, 180 patients underwent pretreatment and 6 month follow-up evaluation with the standard version of the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36). The SF-36 scale scores, means, standard deviations, and 95% confidence intervals were calculated for each SF-36 scale as well as for physical-health-component summary scores (PCS) and mental-health-component summary scores (MCS). Comparisons of these scores were made to U.S. population normative data. Pretreatment and 6-month follow-up SF-36 scores were compared. RESULTS In the 45-54-year age group, all 8 SF-36 scale scores, the PCS, and MCS scores were significantly worse for the HNC patients in comparison with age-matched norms (p < .05). In the 55-64-year age group, the HNC patients were worse in 5 of the 8 SF-36 scale scores and the MCS score in comparison with age-matched norms (p < .05). In the 65-74-year age group, the HNC patients scored significantly worse in the mental health scale. In the comparison of pretreatment and 6-month follow-up scores, the HNC patients had significant decreases in the physical functioning scale (p = .003) and the PCS score (p = .047). The HNC patients showed significant improvement in the mental health scale (p = .049) and improvement in the bodily-pain scale, which approached significance (p = .053) at 6-month follow-up. The HNC patients showed a marked decrease in general health status with increasing stage of HNC. CONCLUSIONS This work provides objective support for the perception that many HNC patients are initially seen for treatment with baseline health status functioning significantly below their age-matched contemporaries in the general population. An educated evaluation of global health outcomes following treatment in the HNC patient population must begin with an accurate pretreatment assessment of these parameters. Self-reported health-status assessment (HSA) is a useful means of evaluating global health status in this patient population.

Abstract
BACKGROUND The purpose of this study was to determine whether head and neck-specific health status domains are distinct from those assessed by general measures of quality-of-life (QOL). METHODS Cross-sectional study of 55 head and neck cancer patients in tertiary academic center was made. Three head and neck-specific measures,-including the Head & Neck Survey (H&NS); a brief, multi-item test which generates domain scores; and a general health measure,-were administered. RESULTS The H&NS was highly reliable and more strongly correlated to the specific measures than to the general measure. Eating/swallowing (ES) and speech/communication (SC) were not well correlated with general health domains. Head and neck pain was highly correlated to general bodily pain (0.88, p < .0001). Despite correlations to some general health domains, appearance (AP) was not fully reflected by any other domain. CONCLUSIONS Head and neck-specific QOL measures are necessary and should include domains that reflect ES, SC, and AP.

Abstract
BACKGROUND The pectoralis major myofascial (PMMF) unit is rapidly mobilized, reliable, and extremely useful in a number of clinical situations calling for vascularized soft-tissue coverage in the head and neck. Although free-tissue transfer has emerged as the preferred method of reconstruction for a large variety of defects in the head and neck, the pectoralis major muscle should be considered when vascularized soft-tissue coverage is required in this area. METHODS A retrospective chart review of 24 PMMF flaps performed at the University of Iowa Hospitals and Clinics between January 1, 1991, and May 1, 1996, was undertaken. Outcomes were evaluated relative to accomplishing the established preoperative surgical goals. RESULTS Utilization of the PMMF flap was grouped according to four primary indications: (1) protection of threatened great vessels or free flap vascular pedicles in situations of wound breakdown due to fistula or infection (7 cases); (2) vascularized soft-tissue coverage of great vessels or free-flap vascular pedicles and prevention of potential wound breakdown in surgical defects in which compromised healing was anticipated (7 cases); (3) closure of small pharyngeal defects (2 cases); or (4) vascularized coverage of the mandible following debridement for osteoradionecrosis (8 cases). The PMMF flap was 100% successful when the surgical goal was to protect exposed vascular structures and promote wound healing in the presence of fistula or infection. The PMMF flap was 100% successful in the protection of vascular structures and prevention of wound breakdown in cases where compromised wound healing was anticipated. The PMMF flap provided closure, and a vascularized surface for mucosalization, when used to primarily reconstruct small pharyngeal defects. The PMMF flap provided definitive closure in 5 of 8 (62.5%) cases of osteoradionecrosis of the mandible when it was used to invest the remaining mandibular bone. Three of 8 cases (37.5%) required further surgical management and were considered failures. An acceptable cosmetic outcome was obtained in women undergoing this procedure by using an inframammary incision. The preoperative goal of the PMMF flap procedure was met in 21 of 24 (87.5%) cases. There was a major complication rate of 12.5% as well as a minor complication rate of 12.5%. CONCLUSION In cases requiring the protection of vital vascular structures from infection, salivary secretions or skin flap breakdown, the PMMF flap should be considered. The PMMF flap is an excellent reconstructive option in selected clinical situations, where vascularized soft-tissue coverage is required in the head and neck.

Abstract
Many papers have addressed the technical aspects of free tissue transfer in head and neck cancer patients. However, there has not been a critical assessment of the impact of free tissue transfer on resource utilization and patient morbidity compared with pedicle flap reconstructions. Two cohorts of patients derived from 245 consecutive reconstructions were tightly matched by age, site, stage, and histology, yielding 44 patient pairs differing in method of reconstruction. Patients undergoing free flap reconstruction spent more time in the operating room than those reconstructed with pedicled flaps (993 min vs. 777 min, P < 0.0001). The group with free flap reconstruction spent fewer days in the surgical intensive care unit and hospital (2 days vs. 2.5 days; 18.5 days vs. 22.6 days). This difference is attributed to the paucity of postoperative complications in the group with free flap reconstruction (fistula formation 4.5% vs. 21%, P < 0.04). These data indicate that the continued use of sophisticated reconstructive techniques in head and neck cancer patients is economically sound as assessed by patient morbidity and resource utilization.

Abstract
BACKGROUND Obtaining adequate surgical margins, free of tumor, is crucial for success in oncologic surgery. The head and neck surgeon often finds that the tumor-free margin reported from histopathologic measurement is significantly smaller than the margin measured in-situ. It was the purpose of this study to quantify the change in size of mucosal and muscle surgical margins following excision, formalin fixation, and slide preparation of tongue and labiobuccal tissue in a canine model. METHODS Ten mongrel dogs under general anesthesia for a concurrent project were used in this study. Changes in mucosal and muscle dimensions around custom-made brass disks, one with a needle depth gauge, were measured immediately following excision after formalin fixation and after slide preparation. RESULTS The mean shrinkage from initial resection to final microscopic assessment of the lingual surface mucosal margins was 30.7% (p < 0.0001). The deep tongue margin shrank 34.5% (p < 0.0001). The mean shrinkage of the labiobuccal mucosal margin was 47.3% (p < 0.0001). In all cases, the greatest proportion of shrinkage occurred immediately upon resection. CONCLUSIONS From the in-situ measurement by the surgeon to final pathologic evaluation on the microscope slide, the measured dimensions of oral cavity mucosal and tongue muscle margins shrink significantly. To obtain 5 mm of pathologically clear margin an in-situ margin of resection of at least 8 to 10 mm needs to be taken. Studies reporting clinical correlation of recurrence and survival information with surgical margin status should include a detailed description of the technique used to determine the reported surgical margin status.

Abstract
BACKGROUND One of several causes of tracheoesophageal puncture (TEP) speech failure after total laryngectomy is disturbance in relaxation of the pharyngoesophageal (PE) segment. We introduce the use of chemical denervation of the PE segment through botulinum neurotoxin (Botox) injection to improve TEP speech. METHODS An analysis was performed on eight patients who received Botox injections for TEP speech problems after total laryngectomy at the University of Iowa between June 4, 1991 and August 8, 1994. Retrospective chart review identified the evolution of pretreatment evaluation and injection technique which became standardized in April 1992. Prospective evaluation of results was recorded by a single speech pathologist who subjectively identified the response to Botox in all patients and recorded pressure readings at the tracheostoma site during speech in 6 patients. RESULTS Seven of the eight patients were noted to have improved TEP speech following injection. Five of these seven patients experienced substantially improved speech, three of whom had no ability to produce speech prior to the Botox injection. CONCLUSION Botox injection is a safe and effective method of improving TEP speech in selected patients with disturbed relaxation of pharyngoesophageal segment.

Abstract
STATEMENT OF PROBLEM Treatment for head and neck malignancies commonly involves radiation therapy. As a result of this therapy the vascular supply to irradiated structures is altered and results in decreased tissue perfusion. In addition to vascular changes, bony structures undergo a reduction in osteoblastic and osteoclastic activity. These tissue alterations, especially in the mandible, enhance the risk of osteoradionecrosis. To avoid this occurrence, many patients who have undergone radiation therapy do not receive elective preprosthetic surgeries, including implant therapy. PURPOSE OF STUDY AND METHODS: This report presents the preliminary results of placing 18 titanium screw implants into previously irradiated mandibles in conjunction with hyperbaric oxygen therapy. RESULTS Of the 18 implants placed, 17 (94%) were judged to be osseointegrated at the abutment connection. One implant did not receive an abutment and was "put to sleep." The remaining 16 (88%) were used for prosthetic rehabilitation. CONCLUSION The use of implants in irradiated tissues may provide a means of enhancing prosthetic rehabilitation while reducing the risk of tissue trauma that may develop into osteoradionecrosis.

Abstract
The use of vascularized free-tissue transfers has given the head and neck surgeon the ability to offer enhanced oncologic therapy with less risk of exposing vital structures to the aerodigestive tract. Resulting free-flap tissue consistencies and contours inhibit the successful use of routine impression techniques. The technique described in this clinical report uses a previously reported procedure to obtain an accurate impression of residual palatal and free-flap structures. The significance of this technique is that it improves the tissue reproduction of surgically closed palatal defects.

Abstract
Thrombosis is the most frequent cause of failure in microvascular free-tissue transfer. The large communicating vein of the cubital fossa connects the deep and superficial venous drainage of the radial forearm free flap (RFFF). This vein allows the surgeon to simultaneously drain both systems by means of the large veins of the cubital fossa. We prospectively collected data on the venous anatomy of the cubital fossa in 40 consecutive RFFFs over a 3-year period. We then retrospectively reviewed available data from the 14 cases preceding the cases in the prospective series. At least 78% of our patients had a communicating vein that facilitated dual venous drainage; 87% of our RFFFs were drained by both the superficial and deep venous systems, and 90% of our RFFFs had two or more venous anastomoses. We had no RFFF failures in our series of 54 flaps. We present our venous anatomy findings in this series of forearms as well as the venous anastomoses of our 54 patients. The surgi- cal-flap harvest, including the communicating vein and its use, may provide an advantage in the dependability and quality of venous outflow.

Abstract
This report describes the case of a chondroid syringoma occurring in the nasofacial groove of a 60-year-old woman. This benign, mixed epithelial tumor is infrequently seen by the otolaryngologist-head and neck surgeon, and therefore may not be included in the differential diagnosis of a nodular lesion on the skin of the head and neck. However, the most frequent site of occurrence for these relatively rare cutaneous lesions is the head and neck region. Histologically, these tumors are quite similar to pleomorphic adenomas of salivary gland origin, and optimal surgical management similarly requires removal of a cuff of normal tissue, rather than a simple shelling out of the lesion. The clinical presentation, pathology and recommended management of this rare tumor are discussed.

Abstract
We describe the replantation of a traumatically severed auricle using microvascular anastomosis to reestablish blood flow to the ear. Microvascular reattachment of the severed auricle occurred 10 hours after the trauma. Postoperatively, adjunctive measures, including anticoagulation and the use of medicinal leeches, were used to relieve venous congestion of the replanted auricle. The replanted auricle healed completely with 100% survival, resulting in an essentially normal-appearing external ear. In the management of a traumatically severed auricle, microvascular replantation should be considered as the intervention of first choice in selected cases. If the procedure is successful, the cosmetic results are excellent; if it is not successful, a number of other reconstructive techniques remain as options.

Abstract
BACKGROUND Serum liver function tests (LFTs) are used in the initial evaluation of patients with head and neck squamous cell carcinoma (SCC) to evaluate hepatic function and to screen for liver metastases. METHODS One hundred forty patients initially seen with SCC between 1988 and 1991 were followed for a minimum of 2 years to determine the significance of abnormal LFTs at presentation. RESULTS Abnormal values were found in 69 patients (49%), including elevated alkaline phosphatase in 37 (26%) and lactic dehydrogenase in 25 (18%). Abnormal values were most commonly attributed to alcohol-related liver disease. No liver metastases were identified at initial screening. LFTs were normal at presentation in all three patients subsequently identified with liver metastases during follow-up. CONCLUSIONS Abnormal LFTs are commonly encountered but are of little value in identifying patients with liver metastases during initial assessment. Modest elevation of LFTs should not necessitate costly and time-consuming investigation to exclude hepatic metastasis.

Abstract
BACKGROUND The radial forearm flap has gained considerable popularity over the past 10 years. With the increasing number of forearm flaps being used in head and neck reconstruction, it is likely that anomalous forearm vascular anatomy will be encountered by more head and neck surgeons performing this procedure. METHODS We reviewed our experience with 52 forearm flaps; four different anomalies of forearm vascular anatomy were encountered in four patients. In this article we present each of our cases and discuss the incidence, preoperative diagnosis, and recommended management of these and the more common forearm vascular anomalies. RESULTS The anomalies encountered in our series include: one case of distal takeoff of the radial artery deep to the pronator teres muscle, two cases of a superficial dorsal antebrachial artery, one case of bilateral hypoplastic ulnar arteries, and one case of high takeoff of the radial artery. CONCLUSIONS There are a number of anomalies of forearm vascular anatomy of clinical significance to the surgeon performing these procedures. Most of these anomalies can be identified with a careful preoperative examination. Surgeons performing this procedure should be familiar not only with the normal vascular anatomy of the forearm flap, but also with the more common anatomic variants. Failure to recognize or appropriately manage these anomalies of forearm vascular anatomy may result in a compromised surgical outcome.

Abstract
OBJECTIVE To review our results using free-tissue transfer to reconstruct midfacial and cranio-orbito-facial defects. DESIGN Case series. SETTING The University of Iowa Hospitals and Clinics, Iowa City. PATIENTS Fourteen of 21 patients had defects that resulted from ablative oncologic surgery; six had severe mid-facial trauma; and one had Romberg's disease. INTERVENTIONS Four latissimus dorsi, 11 rectus abdominis, three scapula, and four forearm free-tissue transfer flaps were used. MAIN OUTCOME MEASURES Adequate flap separation of vital structures (intracranial contents and carotid artery) from the sinonasal or oropharyngeal cavities; restoration of palatal competence, oral diet, and speech intelligibility; maxillary dental rehabilitation; aesthetic results; complications; and the patient's return to social activities outside the home after surgery. RESULTS The intracranial contents (six cases) or carotid artery (four cases) were protected from sinonasal or oropharyngeal contamination by the reconstructive flap in all cases in which this was required. Functional closure of the palate with the flap or a prosthesis was possible in 12 of the 13 patients with a palatal defect; seven of these 13 patients have had full maxillary dental rehabilitation. Twenty patients take an oral diet. Sixteen patients have normal or easily understood speech. Fourteen patients engage in social activities outside the home, and eight have returned to full-time employment. No vascular flap failures occurred in this series. CONCLUSIONS The use of free-tissue transfer flaps is a safe and effective technique for repairing large midfacial and cranio-orbito-facial defects resulting from ablative oncologic surgery or trauma.

Abstract
Hemorrhage into cystic thyroid nodules is a relatively frequent event. Most cases are mild, causing only pain and discomfort, and rarely cause significant neck swelling. Even more rarely, however, massive hemorrhage into a thyroid nodule can result in a rapidly expanding hematoma with airway compromise. We report a case of a rapidly expanding thyroid hematoma that occurred after minor trauma and resulted in airway compromise in a patient with no clinical or surgical evidence of thyroid disease. We also present a review of the literature.

Abstract
The stability of fixation obtained with internal fixation devices (plates and screws) under functional loading of maxillary continuity defects was studied using fresh cadaver skulls. Micromotion (deformation) was recorded in the model across the level of the LeFort I osteotomies even when fixation was thought to be grossly stable. Deformation in this biologically static model proved to be mostly elastic in nature, and the amount of deformation in each skull appeared to be predictable from the average stability of all screws used in each plate. Such motion in viable bone could lead to permanent deformation due to resorption and remodeling of bone around the screws if initial overall fixation stability is tenuous. The results suggest that the term "rigid" is inappropriately used to describe plate and screw fixation of maxillary continuity defects.

Abstract
Primary and secondary reconstruction of mandibular continuity defects with vascularized bone is currently the standard of care at many institutions. The most commonly utilized donor sites for such bone flaps include the scapula, iliac crest, fibula, and radius. Recently, interest has grown in the placement of osseointegrated implants into these flaps to facilitate functional dental rehabilitation. There are no studies comparing the bone available from each of these flaps into which osseointegrated implants can be placed. In this cadaver study, the dimensions of bone available for implant placement from the iliac crest, scapula, fibula, and radius osseous flaps were measured. The iliac crest and fibula flaps had bone dimensions consistently adequate for implant placement. Bone available for the safe placement of implants into the scapula flap was found in the majority of specimens. The radius flap group had the highest number of specimens that were inadequate for implant placement. The majority of the specimens with bone inadequate for implantation were from females. Clinical implications of this study regarding flap selection are discussed.

Abstract
The periocular midface is a complex anatomic region in which the spread of cutaneous malignancies is determined not only by the tumor pathology but also by adjacent natural anatomic barriers. The resulting management considerations when treating malignancies in this region are discussed in this article.

Abstract
This article presents some ideas and techniques for surgical reduction of complicated orbit and nasoethmoid complex fractures in young children. Operative techniques for surgical exposure and fracture reduction and fixation have evolved from standard facial incisions and wire fixation to complete exposure of the cranium and orbits via a bicoronal scalp flap, application of rigid plating techniques, and use of cranial bone grafts when necessary. This evolution of surgical techniques has been accompanied by an overall improvement in cosmetic and functional results.

Abstract
Impaction of the sharp medial edge of the orbital plate of the greater sphenoid wing into the orbital apex is a unique type of lateral orbital wall fracture that can produce a potentially reversible optic neuropathy. Two patients in whom the lateral or temporal approach to the orbit was used to reduce this type of fracture will be presented. In both patients, improvement in vision appeared to be related to removal of a bone fragment compressing the optic nerve in the orbital apex.

Abstract
Fracture dislocations of the middle third of the face usually involve a complex combination of the three types of fractures initially described by LeFort. Treatment of these injuries requires a six- to eight-week period of intermaxillary fixation, unless rigid internal fixation devices (plates and screws) are used to stabilize the fractures. However, rigid fixation carries the risk of producing a malunion and serious malocclusion if not performed correctly. A review of 22 patients with complex LeFort fractures treated with rigid fixation revealed that the only absolute contraindication to its use is difficulty in interdigitating the maxillary and mandibular teeth in a passive fashion at the time of fracture reduction. Rigid internal fixation should therefore be considered as an alternative treatment for most fractures of the middle third of the face.

Abstract
The nature of the binding of aromatic aldehyde and aromatic alcohol substrates to the catalytic zinc of equine liver alcohol dehydrogenase has been studied by using resonance-enhanced Raman spectroscopy. When an excess of both enzyme and coenzyme to substrate is used, a stable ternary chemical intermediate is formed between liver alcohol dehydrogenase and the reduced coenzyme, nicotinamide adenine dinucleotide, and the aldehyde, p-(dimethylamino)benzaldehyde, in the pH range 8.5-0.6. Resonance-enhanced Raman spectra clearly show that this same intermediate is formed between the excess enzyme, oxidized coenzyme, and the corresponding alcohol, p-(dimethylamino)benzyl alcohol. Thus, in the presence of excess enzyme and coenzyme, this specific ternary complex is a stable intermediate for both forward and reverse reactions. As a model for this enzyme-substrate intermediate, a complex between the aldehyde and Zn2+ in diethyl ether was made which showed a resonance-enhanced Raman spectrum essentially identical with that of the enzyme-coenzyme-substrate intermediate and completely different from that of the substrate. Most striking in this spectrum is the total absence of the carbonyl vibration which indicates that the C = O no longer exists in either the enzyme-substrate-coenzyme intermediate or the model complex, most probably due to the presence of a zinc-oxygen bond. The assignments are aided by 18O isotopic substitution in the substrate. The Raman spectra of crystals of the ternary complex and the dynamics of the complex are also discussed.
