Background: Patient delay can contribute to a poor outcome in the management of head and neck cancers (HNC). The main objective of the present study was to investigate the factors associated with patient delay in our population. Materials and Methods: Patients with cancers of the head and neck attending a regional cancer center of North East India were consecutively interviewed during the period from June 2014 to November 2014. The participation of patients was voluntary. The questionnaire included information on age, gender, residential status, educational qualification, monthly family income, any family history of cancer, and history of prior awareness on cancer from television (TV) program and awareness program. Results: Of 311 (n) patients, with an age range of 14-88 years (mean 55.4 years), 81.7% were males and 18.3% females (M:F=4.4). The overall median delay was 90 days (range=7 days-365 days), in illiterate patients the median delay was 90 days and 60 days in literate patients (P=0.002), the median delay in patients who had watched cancer awareness program on TV was 60 days and in patients who were unaware about cancer information from TV program had a median delay of 90 days (p=0.00021) and delay of <10 weeks was seen in 139 (44.6%) patients, a delay of 10-20 weeks in 98 (31.5%) patients, and a delay of 20-30 weeks in 63 (20.2%) patients. Conclusions: Education and awareness had a significant impact in reduction of median patient delay in our HNC cases.

Background and Objectives: Salivary gland tumors are relatively rare and constitute 3% to 4% of all head and neck neoplasms. Their relative infrequency, inconsistent classification, and highly variable biologic behavior make some difficulty, but some general features can be drawn regarding the incidence, pathology, and pattern of behavior of the various benign and malignant tumors of salivary glands. The present study aims to provide a clinical characteristics of salivary gland tumors. Materials and Methods: We analyzed retrospectively clinical features of the 138 patients who were treated surgically at Chonbuk National University Hospital from 1992 through 2002. Results: We found 107 benign and 31 malignant tumors. Among the patients, 58 were males and 80 were females. The most common age group was the fifties. The most common site of both benign and malignant was parotid gland in major salivary glands and palatal region in minor salivary glands. The most common presenting symptom was palpable mass in both benign and malignant tumor. Histopathologically, the most common type was pleomorphic adenoma in benign tumor and mucoepidermoid carcinoma in malignant tumor. All cases were treated surgically and the most common postoperative complications was transient facial nerve weakness. Conclusion: 138 cases of salivary gland tumors were presented with respect to their clinical features.

Background and Objectives: Thunderbeat (TB) and Harmonic scalpel (HS) have been applied to variable head and neck surgery, which are useful for both coagulation and cutting of tissues. However, there have been no comparative studies covering the usefulness of these energy devices in surgery for major salivary gland. In this study, we analyzed the surgical outcomes of two devices in surgery for parotidectomy and submandibular gland (SMG) resection. Materials and Methods: A retrospective chart review of 90 patients including two groups (HS group, n=45 versus TB group, n=45) of patients matched for their patient factors was conducted. Clinicopathologic factors of the patients and surgical outcomes such as the operation time, intraoperative bleeding, amount and duration of drain, hospital stay and complications were compared between two groups. Results: There were no significant difference between two groups regarding the clinicopathologic factors and short-term surgical outcomes. Conclusion: Thunderbeat and HS are both effective and safe for parotidectomy and SMG resection in variable benign disease of major salivary gland.

Background: Head and neck cancers are prevalent in Thailand, in particular in the southern region of the country. However, survival with a large data set has not been reported. The purpose of the present study was to evaluate the survival figures and the prognostic factors in a cohort of patients treated in a university hospital located in the south of Thailand. Patients and Methods: Consecutive new cases of primary carcinoma of the oral cavity, oropharyx, hypopharynx and larynx, treated at Songklanagarind Hospital during 2002 to 2004, were analyzed. The 5-year overall survival rates were obtained by the Kaplan-Meier method. Prognostic factors were identified through multivariate Cox regression analysis. Results: A total 1,186 cases were analyzed. Two-thirds (66.6%) of the cases were at advanced stage (stage III & IV) at presentation. The five-year overall survivals for the whole cohort, oral cavity, oropharynx, hypopharynx and larynx were 24.1%, 25.91%, 19.2%, 13.4%, 38.0% respectively. Stage and treatment type were strong prognostic factors for all sites. An age ${\geq}$ 80 years was associated with poor survival in oral cavity and larynx cancer. Conclusions: The results revealed remarkably poor outcomes of the patients in the series, indicating a strong need to increase the proportion of early stage presentations and maximize the treatment efficacy to improving outcomes. Very old patients are of particular concern for treatment care of oral cavity and larynx cancer.

In head and neck reconstruction, microsurgeons are faced with various demands, such as thin resurfacing, or three-dimensional reconstruction, and therefore, conventional flap as well as perforator flaps are all useful for the functional and aesthetic reconstruction successfully. Among perforator flaps, the pros and cons of anterolateral thigh perforator flap(ALTp) and thoracodorsal perforator flap(TAp) is compared and selected depending on the surgeon's preference, recipient site condition or patient status. Both flaps can be elevated in a chimeric pattern by combining different aspects of tissue components. Customized or tailored reconstruction as well as 3 dimensional reconstructions are all available with perforator flaps and it is useful in head and neck reconstruction. The most outstanding update in head and neck reconstruction is the perforator based island flap (PBIF) compared to conventional flaps. The conventional local flap has evolved on behalf of the perforator concept and its design becomes more flexible and freestyle with less limitations. Actually, random pattern flap is now a misnomer and most conventional local flaps turn into PBIFs. Finally we can say all conventional donor site becomes universal, depending on the surgeons' preference or idea. Moreover, there is no more "flap of choice" and postoperative results are quite variable by surgeons' ability. Operative procedures and plans are very flexible to freestyle flap. With all these advantages, surgeons should be armed with both conventional and perforator concepts for solving any defects or problems.

Background Recent literature has indicated that free flaps are currently considered the preferred choice for head and neck reconstruction. However, head and neck cancer patients are frequently treated with chemoradiotherapy, which is often associated with a poor general and local condition, and thus, such patients are ineligible for free flap reconstruction. Therefore, other reconstruction modalities should be considered. Methods We used lower trapezius musculocutaneous (LTMC) flap based on the dorsal scapular artery to reconstruct head and neck defects that arose from head and neck cancer in 8 patients. All of the patients had undergone preoperative chemoradiotherapy. Results There were no complications except one case of partial flap necrosis; it was treated with secondary intention. Healing in the remaining patients was uneventful without hematoma, seroma, or infection. The donor sites were closed primarily. Conclusions The LTMC flap is the preferred flap for a simple, reliable, large flap with a wide arc of rotation and minor donor-site morbidity. The authors recommend this versatile island flap as an alternative to microvascular free tissue transfer for the reconstruction of defects in the head and neck region, for patients that have undergone preoperative chemoradiotherapy.

Background: Lateral rhinotomy and medial maxillectomy, an en bloc resection of the medial maxillary sinus, ethmoid sinus with the lamina papyracea, medial orbital floor, and lacrimal fossa-duct, have been advocated for lateral nasal wall neoplasms as a standard approach method. Objective: This report was conducted to investigate the clinical efficacy of lateral rhinotomy and medial maxillectomy for lateral nasal wall neoplasms. Materials and Methods: We retrospectively analyzed clinical data of 31 patients who were treated at department of otolaryngology-head and neck surgery, Catholic university of Korea, school of medicine between 1990 and 1996. Results: Twenty five patients had benign lesions(80.6%). By far, the largest percentage was inverted papillomas(80%, 20/25). Of the six malignant lesions(19.4%), 33.3%(2/6) was squamous cell carcinoma and other lesions were metastatic renal cell carcinoma, adecarcinoma, transitional cell cacinoma, and hemangiopericytoma. There were a 4% recurrence for benign tumors(1/25), 5% especially for inverted papilloma(1/20), and 50% for malignant neoplasms(3/6). The overall complication rate was 9.7%. Conclusion: Despite the various approach for treatment of lateral nasal wall neoplasms including inverted papilloma, we continue to advocate a lateral rhinotomy and medial maxillectomy as the treatment of choice.

Background and Objectives Previous studies have suggested the usefulness and importance of postoperative voice therapy, for which there are indirect and direct methods. The aim of this study was to evaluate the efficacy of treatment according to different voice therapy methods. Subjects and Method Patients with vocal polyp were divided into three groups. Group 1 received direct voice therapy after phonomicrosurgery and Group 2 indirect voice therapy after phonomicrosurgery. Group 3 did not receive any voice therapy. Results Perceptual, acoustic, aerodynamic voice outcome parameters differed significantly between pre and post-operative treatments. In almost all of the voice analysis, Group 1, who underwent direct voice therapy, improved more significantly compared with Group 2 and 3. Conclusion Postoperative voice therapy following phonomicrosurgery may be an effective adjuvant treatment in patients with vocal polyps. In particular, direct voice therapy can be effective for improving postoperative voice outcome.

Purpose: This study was to identify the levels of functional status, depression, family support and their relationship among those variables in head and neck cancer patients. Method: The subjects were 100 patients with head and neck cancer patients who visited at outpatients clinic in one university hospital in Taegu. The instrument used for this study were Functional Status in Head & Neck Cancer - Self Report Scale developed by Baker(1995), Self-Rating Depression Scale by Zung(1965) and Family support assessment tool by Kang hyun-suk(1984). The data were analysed percentage, mean, t-test, ANOVA and pearson's corelation using SAS program. Result: There was significantly negative correlation between functional status and depression(r=-.71) and between depression and family support(r=-.56). The relationship of functional status and family support was significant as r= .33. Conclusion: It was found that functional status, depression and family support of head and neck cancer patient were closely related each other. Therefore it is necessary to design nursing intervention to enhance family support or decrease depression for improving quality of life in head and neck cancer patient.

Background and Objectives: Standard treatment of locally advanced laryngeal, hypopharyngeal, and some oropharyngeal cancers includes total laryngectomy. In an attempt to preserve the larynx through induction chemotherapy, we designed induction chemotherapy followed by definitive radiation in patients with potentially respectable head and neck cancer to determine whether organ preservation is feasible without apparent compromise of survival. Materials and Methods: The twenty-six patients diagnosed advanced head and neck squamous cell carcinoma, Stage III or IV (AJCC 2002) and performed organ preservation protocols in Ajou university hospital from 1994 to 2001 were included in this study. Results: Neoadjuvant chemotherapy showed an overall response rate of 84.6% and a complete remission (CR) rate was 59.1% following neoadjuvant chemotherapy and radiation. Seven of thirteen patients were able to preserve their larynges for more than two years by chemotherapy and radiation. There were no treatment related mortality after 2 cycles of induction chemotherapy. Conclusion: Although Organ preservation protocol through neoadjuvant chemotherapy and radiation need more controlled randomized study, it was considered alternative treatment modality in advanced head and neck cancer.
