PURPOSE: The association between tobacco smoking and oral squamous cell carcinoma is well established. However, few studies have evaluated the smoking history based on a smoking versus never-smoking history or analyzed the relationship between smoking history and site and stage of presentation. The purpose of this study was to examine the relationship between smoking versus never-smoking history and the stage and site of presentation of oral squamous cell carcinoma. PATIENTS AND METHODS: The design of this study was a retrospective review of all patients presented at the Legacy Emanuel Hospital Head and Neck Tumor Board in Portland, Oregon, with a biopsy-proven oral squamous cell carcinoma between 1998 and 2000. Data collected included age, gender, smoking history (smoker versus never smoker), pack-years of tobacco, site, and stage (T, N, and group stage) at presentation. RESULTS: A total of 67 patients were reviewed; 33% of patients were never smokers and 67% of patients had a history of smoking with an average of 49.4 pack-years. The floor of mouth and gingiva were the most commonly affected sites. There was a statistically significant difference between site of presentation and a history of smoking (P =.0007). The 2 sites that showed a significant association with smoking were posterolateral tongue and floor of mouth. CONCLUSIONS: The findings of this study demonstrate that approximately one third of patients with oral squamous cell carcinoma will report that they have never smoked. There was a strong association between a history of smoking and carcinoma involving the posterolateral tongue and floor of mouth

PURPOSE: Maxillary reconstruction after maxillectomy remains a great challenge for the reconstructive oral and maxillofacial surgeon. This article is a clinical retrospective analysis of patients reconstructed with zygomaticus implants after maxillary ablation. PATIENTS AND METHODS: The design of the study was a retrospective review of 9 patients requiring near-total or total maxillectomy for pathologic reasons. Clinical records, photographs, and radiographs were studied. Financial billing statements were reviewed to determine charges for implant reconstruction and method of payment. RESULTS: Maxillary reconstruction using zygomaticus and standard endosseous implants was performed in 9 patients. Maxillary resection was performed for the following reasons: salivary gland malignancy (n = 2), squamous cell carcinoma (n = 5), maxillary mucormycosis (n = 1), and extensive maxillary atrophy and infection secondary to subperiosteal maxillary implant placement (n = 1). A total of 28 zygomaticus implants and 10 standard endosseous implants were used to reconstruct the 9 patients. Six zygomaticus implants and 3 standard endosseous implants failed. The time of zygomaticus implant placement ranged from placement at the time of resection to 3.2 years after the resection. Five patients received radiation therapy. Five patients have been reconstructed with a maxillary obturator and have been functioning with the prosthesis for a minimum of 2 years. CONCLUSION: The combination of zygomaticus and standard endosseous implants can be used to reliably reconstruct patients after extensive resection of the maxilla

OBJECTIVE: To determine associations between objective assessments (swallowing function and weight change) and subjective quality-of-life (QOL) measures. DESIGN: Observational case series using clinical testing and questionnaires. SETTING: University hospital-based tertiary clinical practice. PATIENTS: Convenience sample of 5-year survivors of head and neck cancer (62 nonlaryngectomy survivors were studied). INTERVENTIONS: Objective testing included examination, weight history, videofluoroscopic swallow studies (VFSS), and oropharyngeal swallowing efficiency (OPSE). Subjective testing included QOL questionnaires (University of Washington Quality-of-Life [UWQOL] Scale, Performance Status Scale for Head and Neck Cancer Patients [PSS-HN], Functional Assessment of Cancer Treatment-General [FACT-G] Scales, and Functional Assessment of Cancer Therapy-Head and Neck [FACT-H&N] Scale). MAIN OUTCOME MEASURES: Aspiration (identified by VFSS), weight change, and QOL measures. RESULTS: Aspiration was associated with the decreased QOL scores in chewing, swallowing, normalcy of diet, and additional concerns of the FACT-H&N Scale. No association was found between aspiration and willingness to eat in public, subjective understandability, or any of the FACT-G scales. Of the nonlaryngectomy survivors, 27 (44%) demonstrated some degree of aspiration during VFSS. Associations were found between aspiration, primary tumor T stage, weight change, and OPSE. Aspirators lost a mean of 10.0 kg from precancer treatment weight, while nonaspirators gained a mean of 2.3 kg (P<.001). Mean OPSE scores were 69 for nonaspirators and 53 for aspirators (P =.01). CONCLUSIONS: Almost half of long-term nonlaryngectomy head and neck cancer survivors demonstrated at least some degree of aspiration. The presence of aspiration is associated with substantial weight loss, advanced initial tumor stage, diminished oropharyngeal swallowing efficiency, and lower scores on a variety of QOL scales

OBJECTIVES/OBJECTIVE:Placebo response is defined as a change in health status resulting from the symbolic significance attributed by the patient or proxy to the physician encounter. Our goals were to validate the PR12 survey as a measure of placebo response and to analyze the placebo response as a discrete and measurable component of everyday office encounters with the otolaryngologist. STUDY DESIGN/METHODS:This was a prospective, before-and-after clinical outcomes study of 95 children aged 6 months to 12 years conducted in an academic metropolitan pediatric otolaryngology practice. Caregivers completed the PR-12 survey at entry and at least 4 weeks later. The survey included 3 domains (4 questions each) reflecting the main components of the placebo response: meaningful explanation, care and concern, and mastery and control. PR-12 was correlated with longitudinal change in health status at least 1 to 2 months after the baseline visit. Outcome measures included direct and indirect measures of change in disease-specific quality of life and satisfaction with change. RESULTS:Test-retest reliability was fair for most PR-12 survey items (R = 0.41 to 0.76) but was higher for domains (0.60 to 0.66) and the overall survey score (0.66). PR-12 had excellent internal consistency (Cronbach's alpha 0.91) and appropriate construct validity. Caregiver satisfaction change at follow-up correlated with the PR-12 (r = -.25, P = 0.036). Conversely, no correlation was seen between the PR-12 and direct and indirect measures of change in disease specific quality of life. CONCLUSION/CONCLUSIONS:Placebo response is an important and potentially measurable aspect of clinical encounters. PR-12 is a promising first step at creating a brief, reliable, and valid instrument to assess the placebo response. SIGNIFICANCE/CONCLUSIONS:Reemphasizing the therapeutic potential of the doctor-patient relationship may improve quality of care and disease outcomes.

Options for both the cosmetic surgeon offering and patients seeking treatment for cutaneous aging have expanded greatly in recent years and continue to grow. Increasingly sophisticated aesthetic patients are seeking procedures to rejuvenate in record numbers,but many are unwilling to tolerate a large amount of downtime. In expert hands, ablative laser resurfacing has a long history of dramatic results for the treatment of cutaneous aging. During the last decade, there have been a growing number of reports of modalities targeting the more superficial skin structure. Such modalities offer more modest results without the downtime associated with more aggressively ablative procedures.These resurfacing techniques include the use of mechanical, chemical, and thermal forces

Low-grade salivary duct carcinoma is a rare neoplasm. We report on 16 patients, with a median age of 64 years. All but one tumor arose from the parotid gland, including one tumor that arose in an intraparotid lymph node; one arose in the submandibular gland. Tumors consist of single to multiple dominant cysts, accompanied by adjacent intraductal proliferation. Cysts are lined by small, multilayered, proliferating, bland ductal cells with finely dispersed chromatin and small nucleoli. Separate, smaller ductal structures are variably filled by proliferating ductal epithelium with cribriform, micropapillary, and solid areas. The overall appearance is very similar to breast atypical ductal hyperplasia and low-grade ductal carcinoma in situ. Foci of definitive stromal invasion were seen in four tumors. Two tumors demonstrated transition from low- to intermediate- or high-grade cytology, with scattered mitotic figures and focal necrosis. S-100 revealed diffuse strong expression in all 9 cases studied. Myoepithelial markers (calponin) highlighted supportive myoepithelial cells rimming the cystic spaces, confirming the intraductal nature of most, or all, of six tumors studied. Nine tumors studied for Her2-neu antigen were uniformly negative. Follow-up was obtained on 13 of our 16 patients. All patients were disease-free after surgery 6 to 132 months (median 30 months). Low-grade salivary duct carcinoma is a low-grade neoplasm with an excellent prognosis; it may be treated by conservative but complete resection. Its resemblance to atypical breast ductal hyperplasia, or micropapillary/cribriform intraductal carcinoma, distinguishes it from high-grade salivary duct carcinoma, papillocystic acinic cell carcinoma, and cystadenocarcinoma

BACKGROUND: Confocal reflectance microscopy (CRM) is an optical method of imaging tissue noninvasively without the need for fixation, sectioning, and staining as in standard histopathologic analysis. Image contrast is determined by natural differences in refractive indices of organelles and other subcellular structures within the tissues. Gray-scale images are displayed in real time on a video monitor and represent horizontal (en face) optical sections through the tissue. We hypothesized that CRM is capable of discerning histologic characteristics of different tissues in the head and neck. OBJECTIVES: To examine the microscopic anatomy of freshly excised head and neck surgical specimens en bloc using CRM and to compare the findings with those generated by conventional histologic analysis. DESIGN: This was a pilot observational cohort study. Bone, muscle, nerve, thyroid, parotid, and ethmoid mucosa from human surgical specimens were imaged immediately after excision. Confocal images were compared with corresponding routine paraffin-embedded, hematoxylin-eosin-stained sections obtained from the same tissue. RESULTS: Characteristic histologic features of various tissues and cell types were readily discernible by CRM and correlated well with permanent sections. However, in all tissues examined, there was less microscopic detail visible in the CRM images than was appreciated in paraffin-embedded histologic sections. CONCLUSIONS: The CRM images revealed cytologic features without the artifacts of histologic processing and thus may have the potential for use as an adjunct to frozen-section analysis in intraoperative consultation

Blepharoplasty is one of the most common facial cosmetic surgical procedures. When done properly, this relatively simple operation can result in a dramatic improvement for the patient with relatively little downtime. However, when it is performed improperly, the results can be crippling for the patient and often difficult for the surgeon to correct. Standard treatments for upper eyelid dermatochalasis include surgical excision of skin, muscle, and fat. Several techniques have been described for removing some or all of these components, depending on the patients' anatomic requirements. In particular, the "pinch" technique can be used to remove either the upper eyelid skin alone or a combination of skin, muscle, and fat. While this technique is not new, its appearance in the literature is sparse. We demonstrate herein how a modified version of the pinch technique can be used to remove the central orbital fat pad by "sliding" the pad through the medial fat pad incision. This procedure maintains the integrity of the central orbital septum and the delicate structures that lie beneath.
