RESUMO

PURPOSE: The Patient Concern Inventory© (PCI) is a clinical tool of self-reported patient concerns to be used by the clinician to structure the patient-oncologist visit. It was developed in the United Kingdom to address the issues of quality of life (QOL) in head and neck cancer (HNC) patients. The purpose of the study reported here was to determine the prevalence of PCI© items, the associations between PCI© items and QOL, and to explore the importance of oral/dental issues in the patient's well-being. METHODS: The PCI© and the University of Washington (UW-QOLv4) instruments were self-administered by an HNC population in a cross-sectional study. Following an a priori sample size estimate, consecutive HNC patients attending at the University of Florida's Oral Medicine and the ENT Clinics had the study described, eligibility assessed, and if eligible, were invited to participate in the study. Participants completed the PCI© and UW-QOL. PCI© issues prevalence was determined, and for those with a ≥10% prevalence: 1) Fisher's exact test was used to test for statistical differences between treatments, and 2) multivariable regression was used to test each of the prevalent PCI© issues across four QOL measures, health in the last 7 days, overall QOL in the last 7 days, and the physical and social domain scores. RESULTS: Twenty of 45 PCI© issues had a prevalence ≥10%. Of the 15 prevalent items statistically associated with a QOL measure, four issues are the clinical responsibility of the dental profession: 1) chewing/eating, 2) dental health/teeth, 3) mouth opening, and 4) salivation. An additional four (eight total, 50%) are of clinical concern for dental clinicians: 5) pain in head/neck, 6) swallowing, 7) speech/voice/being understood, and 8) taste. CONCLUSIONS: Dental concerns represent almost half of all PCI© concerns observed in 10% or more of the sample patients. Prosthodontists should support our maxillofacial prosthodontics specialists in joining other oral oncologists and advocate for comprehensive, integrated dental support for HNC patients by assuring dental involvement/inclusion with the multidisciplinary oncology team and a research agenda to established best patient-centered outcomes.

RESUMO

PURPOSE: This is a retrospective analysis of the 50-year University of Florida experience treating adenoid cystic carcinoma of the lacrimal gland with radiation therapy. MATERIALS AND METHODS: Between 1965 and 2015, 8 patients with adenoid cystic carcinoma of the lacrimal gland received radiation therapy with curative intent. Four patients received postoperative radiation therapy and 4 received definitive radiation therapy alone. The median follow-up was 3.3 years (range, 0.3 to 11.2 years). RESULTS: All 4 patients who received postoperative radiation therapy received 74.4 Gy. The 4 patients who received radiation therapy alone received a median dose of 72.3 Gy (range, 70.0 to 74.4 Gy). The overall survival rates at 5 and 10 years were 25% and 13%, respectively. The cause-specific survival rates at 5 and 10 years were 29% and 14%, respectively. The local control and freedom from metastases rates at 5 and 10 years were both 43%. Local recurrences occurred in 50% of patients, and distant metastatic disease occurred in 38% of patients. No patients experienced acute complications of treatment that warranted a treatment break. Two patients experienced bone exposure as late complications of treatment. CONCLUSIONS: The results of this study illustrate the propensity for adenoid cystic carcinoma of the lacrimal gland to recur both locally and with distant metastases despite aggressive local treatment measures. This study also demonstrates the relatively poor outcomes for individuals with this type of tumor.

RESUMO

The purpose of this study is to report our institutional experience using radiotherapy in the treatment of ameloblastoma and ameloblastic carcinoma. Three patients with ameloblastoma and 3 patients with ameloblastic carcinoma were treated with radiotherapy alone (2 patients) or surgery and postoperative radiotherapy (4 patients) at the University of Florida between 1973 and 2007. Follow-up ranged from 4.0 to 13.1 years with a median of 7.8 years. Radiotherapy complications were scored using the Common Terminology Criteria for Adverse Events, version 4.0. Local control was achieved in 4 of the 6 patients. One patient treated with RT alone for an unresectable ameloblastoma developed a local recurrence and metastases in both the cervical lymph nodes and lungs, but had excellent response to dual BRAF/MEK inhibition with dabrafenib and trametinib. Another patient treated with surgery and postoperative radiotherapy for an ameloblastic carcinoma recurred locally without metastasis, but was not salvaged. No significant treatment-related complications were observed. For patients with local recurrence or inadequate margins after surgery, adjuvant radiotherapy provides the potential for disease control. In the setting of metastatic disease, targeted therapies may provide an additional opportunity for salvage.

RESUMO

The objective of this study is to determine if radiotherapy (RT) alone to the cervical lymphatics is a suitable alternative to elective neck dissection (END) in patients who undergo parotidectomy and postoperative RT for squamous cell carcinoma metastatic to the parotid area lymph nodes (PALN). We retrospectively reviewed the medical records of 107 patients consecutively treated from November 1969 to March 2012 for cutaneous squamous cell carcinoma metastatic to the PALN with a clinically node-negative neck. Primary therapy consisted of parotidectomy in all cases. We compared regional (cervical) control in two subgroups: 42 patients treated with END and RT and 65 patients treated with elective neck irradiation (ENI) alone. The median time of follow-up was 5.5 years (range 0.3-30 years) for all patients and 11 years for living patients (range 1.8-26 years). There was 1 neck recurrence in each subgroup: END and RT, 1/42 (2 %); and ENI alone, 1/65 (1.5 %). No patient experienced a complication related to neck RT. ENI to a dose of approximately 50-60 Gy is a suitable alternative to END and postoperative RT in patients with squamous cell carcinoma metastatic to the PALN.

RESUMO

The objective of this study is to report the long-term outcomes of primary radiotherapy (RT) for patients with T1-T2 squamous cell carcinomas (SCC) of the pyriform sinus. Between November 1964 and March 2008, 135 patients with T1-T2 pyriform sinus SCC were treated with primary RT at the University of Florida. Adjuvant chemotherapy was employed in 21 patients (16 %) and 62 patients (46 %) underwent a planned neck dissection. Median follow-up was 3.5 years (range 0.2-24.7 years); median follow-up on living patients was 8.3 years (range 3.8-24.0 years). The 5-year outcomes were as follows: local control, 85 %; regional control, 81 %; local-regional control, 71 %; distant metastasis-free survival, 76 %; cause-specific survival, 62 %; and overall survival, 38 %. The 5-year local control rate was 88 % for T1 cancers and 84 % for those with T2 SCCs (p = 0.5429). Sixteen patients (12 %) experienced severe late complications. Primary RT results in a high probability of cure with a relatively modest risk of severe late complications for patients with T1-T2 SCCs of the pyriform sinus.

RESUMO

This study is aimed at updating our institution's experience with definitive radiotherapy (RT) for squamous cell carcinoma of the tonsil. We reviewed 531 patients treated between 1983 and 2012 with definitive RT for squamous cell carcinoma of the tonsil. Of these, 179 patients were treated with either induction (n = 19) or concomitant (n = 160) chemotherapy. Planned neck dissection was performed on 217 patients: unilaterally in 199 and bilaterally in 18 patients. Median follow-up was 5.2 years for all patients (range 0.1-31.6 years) and 8.2 years for living patients (range 1.9-31.6 years). The 5-year local control rates by T stage were as follows: T1, 94 %; T2, 87 %; T3 79 %; T4, 70 %; and overall, 83 %. Multivariate analysis revealed that local control was significantly influenced by T stage and neck dissection. The 5-year cause-specific survival rates by overall stage were as follows: I, 94 %; II, 88 %; III, 87 %; IVA, 75 %; IVB, 52 %; and overall, 78 %. Multivariate analysis revealed that cause-specific survival was significantly influenced by T stage, N stage, overall stage, fractionation, neck dissection, sex, and ethnicity. Of 77 patients treated with ipsilateral fields only, contralateral neck failure occurred in 1 %. The rate of severe complications was 12 %. Definitive RT for patients with tonsillar squamous cell carcinoma provides control rates equivalent to other modalities with a comparatively low incidence of late complications. Patients with anterior tonsillar pillar or tonsillar fossa primaries that are well lateralized with no base of tongue or soft palate extension may be treated with ipsilateral fields.

RESUMO

We evaluated the treatment of squamous cell carcinoma (SCC) of the nasal vestibule. Eighty-six patients were treated with radiotherapy (RT) and 13 patients received surgery and RT. The mean follow-up was: 9.7 years (range 4 months-35.9 years). The 5- and 10-year outcomes were: local control (LC), 88 and 82 %; local-regional control (LRC), 78 and 73 %; freedom from distant metastases (FFDM), 96 and 96 %; cause-specific survival (CSS), 91 and 86 %; and overall survival, 75 and 51 %. The 5- and 10-year LC rates for patients treated with RT were 94 and 89 % overall. A multivariate analysis was performed. Tumor size predicted LC, LRC, OS, and CSS. Overall stage predicted LRC. RT cures most patients with T1-T2 and favorable T4 SCCs with acceptable toxicity. RT and surgery result in improved likelihood of cure for patients with advanced T4 lesions.

RESUMO

The purpose of this study is to update our institution's experience with ipsilateral radiation therapy (RT) for squamous cell carcinoma of the tonsillar area. Outcome study of 76 patients treated between 1984 and 2012 with ipsilateral RT for squamous cell carcinoma of the tonsil. Patients had either cT1 (n = 41, 54 %) or cT2 (n = 35, 46 %) primaries and cN0 (n = 27, 36 %), cN1 (n = 15, 20 %), cN2a (n = 8, 11 %), or cN2b (n = 26, 34 %) nodal disease. Of these, 32 (42 %) patients underwent a planned neck dissection and 21 (28 %) patients received concomitant chemotherapy. Median follow-up for all patients was 7.1 years (range 0.1-27.2) and 7.8 years (range 2.1-27.2 years) for living patients. The 2- and 5-year control and survival rates were as follows: local control, 98.6 and 96.9 %; local-regional control 95.8 and 92.6 %; cause-specific survival 95.9 and 93.1 %; and overall survival, 92.1 and 83.8 %. One patient failed in the contralateral, non-radiated neck 3 years after primary treatment. Univariate analysis revealed that overall survival was significantly influenced by whether the patient had a primary tumor in the anterior tonsillar pillar versus the tonsillar fossa with the latter performing better. The incidence of severe late complications was 16 %. Ipsilateral RT for patients with squamous cell carcinoma of the anterior tonsillar pillar or tonsillar fossa with no base of tongue or soft palate extension is an efficacious treatment that provides excellent control rates with a relatively low incidence of late complications.

RESUMO

PURPOSE/OBJECTIVES: Treatment outcomes were analyzed for patients who received radiotherapy for squamous cell carcinoma of the retromolar trigone at a single institution. MATERIALS/METHODS: We reviewed the medical records of 110 patients treated with radiotherapy alone (n=36) or radiotherapy combined with surgical resection of the primary tumor (n=74) between June 1966 and October 2013. The median follow-up was 4.5years for all patients and 11.8years for living patients (range, 1.3-23.5years). RESULTS: The 5-year local-regional control rates after definitive radiotherapy versus surgery and radiotherapy for stages I-III were 52% and 89% and for stage IV they were 46% and 58%, respectively. The 5-year cause-specific survival rates after definitive radiotherapy compared with surgery and radiotherapy for stages I-III were 57% and 82% and for stage IV they were 45% and 43%, respectively. Multivariate analyses revealed that the likelihood of cure was better with surgery and radiotherapy compared with radiotherapy alone (p=0.041). CONCLUSION: Patients treated with surgery and radiotherapy had a better chance of cure than those treated with radiotherapy alone. Complications of treatment were common in both groups but more common in patients who underwent surgery.

RESUMO

BACKGROUND: Paragangliomas of the head and neck are rare, slow-growing, generally benign tumors of neuroendocrine cells associated with the peripheral nervous system that commonly involve the carotid body, jugular bulb, vagal ganglia, and temporal bone. Treatment options include surgery, radiotherapy (RT), stereotactic radiosurgery (SRS), and observation. This article briefly reviews our 45-year institutional experience treating this neoplasm with RT. METHODS: From January 1968 through March 2011, 131 patients with 156 benign paragangliomas of the temporal bone, carotid body, jugular bulb, or glomus vagale were treated with RT at a median dose of 45 Gy in 25 fractions. The mean and median follow-up times were 11.5 years and 8.7 years, respectively. RESULTS: Five tumors (3.2%) recurred locally after RT, all within 10 years of treatment. The overall local control rates at 5 and 10 years were 99% and 96%, respectively. The cause-specific survival rates at 5 and 10 years were 98% and 97%, respectively. The distant-metastasis free survival rates at 5 and 10 years were 99% and 99%, respectively. The overall survival rates at 5 and 10 years were 91% and 72%, respectively. There were no severe complications. CONCLUSION: RT for benign head and neck paragangliomas is a safe and efficacious treatment associated with minimal morbidity. Surgery is reserved for patients in good health whose risk of associated morbidity is low. SRS may be suitable for patients with skull base tumors <3 cm where RT is logistically unsuitable. Observation is a reasonable option for asymptomatic patients with a limited life expectancy.

RESUMO

PURPOSE: To evaluate the long-term effectiveness of radiotherapy (RT) in the treatment of sinonasal undifferentiated carcinoma (SNUC). MATERIALS AND METHODS: The medical records of 23 patients treated with definitive or postoperative RT between 1992 and 2010 at the University of Florida were retrospectively reviewed. Fifteen patients (65%) received primary surgery and postoperative RT. Radiation doses ranged from 59.0 to 74.8 Gy (median, 70.2 Gy). The median follow-up time for all patients was 3.0 years (range, 0.9-19.9), and for living patients was 7.7 years (range, 2.5-19.9). RESULTS: The actuarial 5-year survival outcomes were as follows: progression-free survival, 42%; cause-specific survival, 43%; and overall survival, 32%. Actuarial 5-year disease control rates were as follows: local control (infield or marginal), 74%; local-regional control (excluding leptomeningeal spread), 58%, regional control 78%, freedom from leptomeningeal recurrence, 72%, and distant metastasis-free survival, 73%. Five of the 8 (62.5%) patients treated with definitive RT died with disease, and 6 of the 15 patients (40%) treated with primary surgery and postoperative RT died with disease. Three patients (13%) experienced severe complications including unilateral eye removal, osteoradionecrosis of the maxilla requiring hyperbaric oxygen and surgery, and brain necrosis. One patient died due to an infected bone graft and brain abscess. CONCLUSIONS: A multimodal approach is best when treating SNUC patients. The prognosis for patients treated with definitive RT ± chemotherapy is less promising than for those who receive surgery and postoperative RT ± chemotherapy. Severe complications occur in about 17% of patients due to the high dose of RT alone or combined with surgery required for acceptable disease control.

RESUMO

PURPOSE: To assess the efficacy of postoperative radiotherapy (RT) in the treatment of cutaneous melanoma. MATERIALS: Between August 1981 and December 2009, 82 patients were treated with surgery and postoperative RT for cutaneous melanoma. Patients were thought to be high risk for local-regional recurrence after surgery alone because of the presence of one or more risk factors including recurrence after prior surgery, positive lymph nodes, extracapsular extension, incomplete regional node dissection, microscopically positive margins, gross residual disease, and in-transit metastases. The primary site was located in the head and neck in 64 patients and elsewhere in the remainder. Forty-two patients (47%) were treated with hypofractionated RT and the remainder with conventional fractionation. Median age was 62 years (range, 21 to >89 years). Median follow-up overall and for survivors was 3.0 years (range, 0.1 to 17.4 years) and 6.4 years (1.6 to 17.4 years), respectively. RESULTS: The 5-year outcomes were: in-field local-regional control 82%; local-regional control, 76%; distant metastasis-free survival, 48%; cause-specific survival, 56%; and overall survival, 43%. In-field local-regional control at 5 years was 87% after hypofractionated RT and 78% after conventionally fractionated RT. CONCLUSIONS: Postoperative adjuvant RT likely reduces the risk of local-regional recurrence after surgery for patients with high risk cutaneous melanoma. Hypofractionated RT is as effective as conventional fractionation and is logistically advantageous, particularly for patients with a relatively poor prognosis. The risk of RT complications is low.

RESUMO

PURPOSE: The aim of this study was to update our experience in treating pleomorphic adenoma with radiotherapy (RT). MATERIALS AND METHODS: This is a retrospective analysis of 25 patients treated with RT alone (2 patients) or combined with surgery (23 patients), with follow-up ranging from 1.8 to 34.9 years (median, 10.5 years). RESULTS: Local control was achieved in 13 (75%) of 16 patients with subclinical disease and 5 (56%) of 9 patients with gross disease. Overall local control was achieved in 18 (72%) of 25 patients. The 5-, 10-, and 15-year overall local control rates were 76 %, 76%, and 68%, respectively. Ten patients died of the following causes: recurrent disease, 2; malignant transformation, 2; and intercurrent disease, 6. At last follow-up, 14 patients were alive without evidence of disease, and 1 patient was alive with disease. Dental carries and transient facial nerve deficits were the most common complications. No patients developed severe complications subsequent to RT. CONCLUSIONS: In patients at high risk for developing recurrent pleomorphic adenoma after surgery, RT is effective in controlling subclinical disease.

RESUMO

PURPOSE: To determine whether patients with clinically node negative (cNo) high grade salivary gland carcinomas benefit from an elective neck dissection prior to postoperative radiotherapy (RT). MATERIAL/METHODS: Between October 1964 and October 2009, 59 previously untreated patients with cNo high-grade salivary gland carcinomas (squamous cell carcinomas were excluded) were treated with curative intent using elective neck dissection (END; n=41), or elective neck irradiation (ENI; n=18) at the University of Florida College of Medicine (Gainesville, FL). All patients underwent resection of the primary cancer followed by postoperative RT. The median follow-up period was 5.2years (range, 0.3-34years). RESULTS: Occult metastases were found in 18 (44%) of the 41 patients in the END group. There were 4 recurrences (10%) in the END group and 0 recurrence in the ENI group. Neck control rates at 5years were: END, 90%; ENI, 100%; and overall, 93% (p=0.1879). Cause-specific survival was 94% in the ENI group, 84% in the END group, and 86% for all patients (p=0.6998). There were 3 reported grade 3 or 4 toxicities. Two patients had a postoperative fistula and one patient had a grade 4 osteoradionecrosis that required a partial mandibulectomy. CONCLUSIONS: Patients with cNo high grade salivary gland carcinomas who are planned to undergo surgery and postoperative RT likely do not benefit from a planned neck dissection.

RESUMO

PURPOSE: The aim of this study was to describe the treatment outcomes of patients with cutaneous Merkel cell carcinoma managed with curative intent. MATERIALS AND METHODS: Between December 1984 and November 2009, 40 patients with previously untreated Merkel cell carcinoma were managed with curative intent with radiotherapy alone (3 patients) or combined with surgery (37 patients). Adjuvant chemotherapy was administered to 11 patients. Primary sites were the following: head and neck, 32 patients; extremities, 6 patients; and trunk, 2 patients. Patients were staged according to the Yiengpruksawan staging system: stage I, local disease; stage II, regional disease; and stage III, distant metastases. Twenty-four patients had stage I disease, and 16 patients had stage II disease. Median follow-up on all patients was 3.0 years (range, 0.6-15.6 years). Median follow-up on survivors was 4.2 years (range, 2.2-14.2 years). RESULTS: The 5-year outcomes were local control, 92%; regional control, 78%; local-regional control, 79%; distant metastasis-free survival, 57%; cause-specific survival, 45%; and overall survival, 36%. The 5-year outcomes for those with stage I vs stage II disease were the following: local-regional control, 87% and 67% (P = .1607); distant metastasis-free survival, 71% and 37% (P = .0073); cause-specific survival, 58% and 27% (P = .0090); and overall survival, 48% and 18% (P = .0037). Local-regional recurrences were observed in 6 patients; one patient was successfully salvaged. Severe complications were observed in 3 patients. CONCLUSIONS: Radiotherapy alone or combined with surgery results in a high local-regional control rate. The main mode of recurrence is distant. Approximately one half of patients are cured.

RESUMO

PURPOSE: To report our experience using radiotherapy alone or combined with surgery to treat adenoid cystic carcinoma of the head and neck. MATERIALS AND METHODS: Radiotherapy alone or combined with surgery was used to treat 120 previously untreated patients with adenoid cystic carcinoma (ACC) of the head and neck from August 1966 to March 2008. Patients were treated with curative intent. American Joint Committee on Cancer stage distribution was,T0 (n = 1), T1 (n = 26), T2 (n = 25), T3 (n = 14), T4 (n = 54), N0 (n = 113), N1 (n = 2), N2a (n = 1), N2b (n = 2), and N2c (n = 2). Treatment included surgery with postoperative radiotherapy (n = 71), radiotherapy alone (n = 46), and preoperative radiotherapy and surgery (n = 3). Incidental and clinical perineural invasion was found in 41 (34%) and 35 (29%) patients, respectively. Median follow-up was 8.6 and 11.6 years overall and among living patients, respectively. RESULTS: The 10-year overall, cause-specific, and distant metastasis-free survival rates, respectively, were as follows: radiotherapy alone, 37%, 46%, and 76%; surgery and radiotherapy, 57%, 71%, and 62%; and overall, 50%. The 10-year local control rates were as follows: radiotherapy alone, 36%; surgery and radiotherapy, 84%; and overall, 65%. The 10-year neck control rates were as follows: elective nodal irradiation (ENI), 98%; no ENI, 89%; and overall, 95%. CONCLUSIONS: Surgery and adjuvant radiotherapy offer the best chance for cure for patients with resectable adenoid cystic carcinomas of the head and neck. Some patients with advanced, incompletely resectable disease can be cured with radiotherapy alone. ENI should be considered for primary sites located in lymphatic-rich regions.

RESUMO

OBJECTIVE: The objective of the study was to discuss the optimal management and treatment outcomes for patients with head and neck osteosarcomas. STUDY DESIGN: Review article. METHODS: Review of the pertinent literature. RESULTS: Osteosarcomas account for approximately 1% or less of all head and neck cancers. The vast majority occur in the mandible and maxilla. The median age is in the fourth decade, with a wide range. They are more likely to recur locally after treatment and distant metastases are observed less often than with the more common osteosarcomas arising in the long bones. The optimal treatment is complete resection. The role of adjuvant chemotherapy is ill-defined. The vast majority of recurrences are observed within 5 years. The 5-year disease-specific and overall survival rates are approximately 60% to 70%. CONCLUSIONS: Osteosarcoma of the head and neck is a rare entity that occurs primarily in the mandible and maxilla. The optimal treatment is surgery. Adjuvant radiotherapy should be considered for those with close or positive margins. The role of adjuvant chemotherapy is ill-defined. The likelihood of cure is approximately 60% to 70%.

RESUMO

PURPOSE: To report the long-term results after definitive radiotherapy (RT) for T1-T2 pyriform sinus squamous cell carcinoma. PATIENTS AND METHODS: The data from 123 patients with T1-T2 pyriform sinus squamous cell carcinoma treated with RT with or without neck dissection between November 1964 and June 2003 were analyzed. The median follow-up for all patients was 3.2 years, and the median follow-up for living patients was 10.7 years. RESULTS: The 5-year local control, locoregional control, freedom from distant metastasis, cause-specific survival, and overall survival rate was 85%, 70%, 75%, 61%, and 35%, respectively. The ultimate local control rate, including successful salvage of RT failure, for T1 and T2 cancer patients was 96% and 94%, respectively. The overall local control rate with a functional larynx was 83%. Pretreatment computed tomography tumor volume data were available for 55 patients. The median computed tomography tumor volume was 4.2 cm(3) (range, 0-22.4). Local control was worse for patients with a tumor volume >6.5 cm(3) compared with those with a smaller tumor volume. Of the 123 patients, 16% developed moderate to severe acute (2%), late (9%), or postoperative (5%) complications. CONCLUSIONS: Local control with larynx preservation after definitive RT for T1-T2 pyriform sinus squamous cell carcinoma likely results in local control and survival similar to that after total laryngectomy or larynx-conserving surgery. Two-thirds of our living patients retained a functional larynx.

RESUMO

The management of head and neck cancer has evolved into a multidisciplinary approach in which patients are evaluated before treatment and decisions depend on prospective multi-institutional trials, as well as retrospective outcome studies. The choice of one or more modalities to use in a given case varies with the tumor site and extent, as exemplified in the treatment of laryngeal squamous cell carcinomas. The goals of treatment include cure, laryngeal voice preservation, voice quality, optimal swallowing, and minimal xerostomia. Treatment options include transoral laser excision, radiotherapy (both definitive and postoperative), open partial laryngectomy, total laryngectomy, and neck dissection. The likelihood of local control and preservation of laryngeal function is related to tumor volume. Patients who have a relatively high risk of local recurrence undergo follow-up computed tomography scans every 3-4 months for the first 2 years after radiotherapy. Patients with suspicious findings on computed tomography might benefit from fluorodeoxyglucose positron emission tomography to differentiate post-radiotherapy changes from tumor.

RESUMO

OBJECTIVE: To characterize orthonasal and retronasal olfactory ability in patients who have had a total laryngectomy (TL). DESIGN: Prospective psychophysical evaluation of orthonasal and retronasal olfactory function. SETTING: Academic center outpatient clinic. PATIENTS: Volunteer sample of 36 subjects who underwent laryngectomy 0.5 to 25.0 years after TL (median, 3.5 years) and 36 age-, sex-, and smoking history-matched controls. MAIN OUTCOME MEASURES: Scores on established psychophysical tests of orthonasal and retronasal olfaction and self-rating scores of smell assessed with a visual analog scale. RESULTS: Assessment of orthonasal olfactory ability yielded a mean composite score of 4.3 (maximum score, 7) for the TL group and 5.3 for the control group (P = .002). Evaluation of retronasal olfactory ability resulted in a mean score of 11.0 (maximum score, 20) for the TL group vs 14.3 for the control group (P<.001). The mean self-rating scores of smell were 2.9 and 6.6 (maximum score, 10) for the TL and control groups, respectively (P<.001). Self-ratings of smell positively correlated with orthonasal (r(S) = 0.42; P<.001) and retronasal (r(S) = 0.50; P<.001) olfactory ability. CONCLUSIONS: Laryngectomy is associated with measurable decreases in olfactory function that are also subjectively perceived. Quantification of decrements in orthonasal and retronasal olfactory function can be used to characterize the severity of hyposmia and to assess the potential for, and efficacy of, olfactory rehabilitation. Although self-assessment with a simple visual analog scale successfully identifies many laryngectomy patients who have objective evidence of olfactory dysfunction, further investigation is necessary to evaluate and compare its validity and reliability with other available survey instruments that purport to measure olfaction.
