Abstract
Mechanisms of sex-dependent orofacial pain are widely understudied. A significant gap in knowledge exists about comprehensive regulation of tissue-specific trigeminal sensory neurons in diseased state of both sexes. Using RNA sequencing of FACS sorted retro-labeled sensory neurons innervating tongue tissue, we determined changes in transcriptomic profiles in males and female mice under naïve as well as tongue-tumor bearing conditions Our data revealed the following interesting findings: (1) FACS sorting obtained higher number of neurons from female trigeminal ganglia (TG) compared to males; (2) Naïve female neurons innervating the tongue expressed immune cell markers such as Csf1R, C1qa and others, that weren't expressed in males. This was validated by Immunohistochemistry. (3) Accordingly, immune cell markers such as Csf1 exclusively sensitized TRPV1 responses in female TG neurons. (4) Male neurons were more tightly regulated than female neurons upon tumor growth and very few differentially expressed genes (DEGs) overlapped between the sexes, (5) Male DEGs contained higher number of transcription factors whereas female DEGs contained higher number of enzymes, cytokines and chemokines. Collectively, this is the first study to characterize the effect of sex as well as of tongue-tumor on global gene expression, pathways and molecular function of tongue-innervating sensory neurons.

Abstract
Simple Summary With increasing long-term survivorship of head and neck cancer (HNC), the functional outcomes are gaining importance. Recently, a tool for the rapid clinical assessment of the functional status in HNC-patients based on observable clinical criteria, termed “HNC-Functional InTegrity (FIT) Scales, was validated. Here, the functional outcomes of 681 newly diagnosed HNC-patients were reported using the HNC-FIT Scales. A normal/near-normal outcome in all six functional domains was observed in 61% of patients, with individual scores of 79% for food intake, 89% for breathing, 84% for speech, 89% for pain, 92% for mood, and 88% for neck and shoulder mobility. Clinically relevant impairment in at least one functional domain was observed in 30% of patients, and 9% had loss of function in at least one functional domain. Thus, clinically relevant persistent functional deficits in at least one functional domain must be expected in 40% of HNC-patients. The treatment of these functional deficits is an essential task of oncologic follow-up. Abstract With the increase in long-term survivorship of head and neck cancer (HNC), the functional outcomes are gaining importance. We reported the functional outcomes of HNC patients using the HNC-Functional InTegrity (FIT) Scales, which is a validated tool for the rapid clinical assessment of functional status based on observable clinical criteria. Patients with newly diagnosed HNC treated at the Medical University of Innsbruck between 2008 and 2020 were consecutively included, and their status in the six functional domains of food-intake, breathing, speech, pain, mood, and neck and shoulder mobility was scored by the treating physician at oncological follow-up visits on a scale from 0 (loss of function) to 4 (full function). HNC-FIT scales were available for 681 HNC patients at a median of 35 months after diagnosis. The response status was complete remission in 79.5%, 18.1% had recurrent or persistent disease, and 2.4% had a second primary HNC. Normal or near-normal scores (3 and 4) were seen in 78.6% for food intake, 88.7% for breathing, 83.7% for speech, 89% for pain, 91.8% for mood, and 87.5% for neck and shoulder mobility. A normal or near-normal outcome in all six functional domains was observed in 61% of patients. Clinically relevant impairment (score 1–2) in at least one functional domain was observed in 30%, and 9% had loss of function (score 0) in at least one functional domain. The main factors associated with poor functional outcome in a multivariable analysis were recurrence or persistent disease, poor general health (ASA III and IV), and higher T stage. Particularly, laryngeal and hypopharyngeal tumors impaired breathing and speech function, and primary radiation therapy or concomitant systemic therapy and radiotherapy worsened food intake. Clinically relevant persistent functional deficits in at least one functional domain must be expected in 40% of the patients with HNC. The treatment of these functional deficits is an essential task of oncologic follow-up.

Abstract
Objective: Treatment of tongue cancer caused oral morbidities such as oral dryness, and dysphagia. The purpose of this study is to examine the time course of oral function and QOL based on resected area for patients after tongue cancer resection. Methods: 31 patients who underwent tongue cancer resection at the Showa University Head and Neck Oncology Center. The participants were divided into two groups; 24 participants in partial/hemi glossectomy group (PG), and seven in subtotal/total glossectomy group (TG). Participants were evaluated swallowing function (FOIS and MASA-C), tongue pressure (TP: kPa), BMI, whole body muscle mass (kg), and QOL evaluation (EORTC QLQ-C30, H & N35). Participants were measured at baseline (before surgical treatment), 1, 3, and 6 months after surgical treatment (1M, 3M, and 6M). Results: At baseline, tongue pressure and FOIS score of PG were significant higher than that of TG. At 1M, TP, MASA-C, and FOIS score of PG were significant higher than that of TG. At 3M, TP, MASA-C, and FOIS score of PG were significant higher than that of TG. At 6M, TP and MASA-C were significantly higher than that of TG. QOL measurements did not noted any significant difference between groups before 6M. At 6M, Some QOL measurements of TG related tongue function (Swallowing, Senses, Speech, Social contact) were significantly lower than PG. Conclusions: The resected area had significant effects on oral morbidities and feeding function. It is necessary to develop more effective rehabilitation methods to improve patients QOL who had functional impairment remained.

Abstract
The diagnosis of cancer and its treatment have an incomparable impact on a patient's life. In the early postoperative stages after the surgical treatment of oral squamous cell carcinoma (OSCC), functions and well-being are limited, which leads to a fundamental decline of the quality of life (QoL). To date, no studies have been performed that focus on the development of special aspects during the time of the in-patient stay of OSCC patients. With the results of this cross-sectional study, we are able to identify those patients who tend to require special support. This cross-sectional study determined the postoperative QoL with a questionnaire (QU) that was handed out twice to OSCC patients after surgery during their inpatient stay. The questions were based on the European Organisation for Research and Treatment of Cancer (EORTC)'s Quality of Life Questionnaire (QLQ)-C30 and QLQ-H&N35. In our study, we found that for postoperative OSCC patients, eating, swallowing and speech were influenced the most. After decannulation, tracheotomy showed no impact on functions. Social contact was impaired at both timepoints. Especially female patients consider themselves to be more impaired on the scale of social contact. QoL should be checked with a standardized QU as an established tool during hospitalization in every oncology department. Only this procedure can pinpoint those patients who have struggles with their surgical outcome and need more assistance.

Abstract
Mandibular resections have a dramatic effect on oral cavity functions. Ablative surgical defects are complex which are better reconstructed with free flaps. In developing countries like India, where majority of patients come from low socioeconomic status, pectoralis major myocutaneous flap is the most preferred reconstructive option. A retrospective questionnaire study was carried out to assess the mastication in patients with mandibulectomy followed by pectoralis major myocutaneous flap reconstruction. At the end of the study, it was observed that 86.6% of the patients had a good performance despite the lack of bony reconstruction. Thus, pectoralis major myocutaneous flap still stands strong in reconstructing large oral cavity defects.

Abstract
PURPOSE Head and neck cancer (HNC) patients experience various posttreatment side effects that decrease quality of life (QOL). Some previous study reported that QOL of HHC patients were returned baseline (before treatment) after a year post treatment. However, acute stage longitudinal changes of QOL in HNC patients remains unclear. This point might be important for early reintegration of HNC patients. This study aimed to investigate the acute stage longitudinal change of the relationship between QOL and oral function in HNC patients had surgery. METHODS 45 HNC patients (23 men) scheduled for surgical treatment were enrolled in this study. Primary tumor sites were 22 tongue, 5 maxilla, 4 mandible, 3 pharynx and others. Weight, body mass index (BMI), whole body soft lean mass (SLM), and skeletal muscle mass (SMM) were evaluated as muscle mass-related measurements. Lip closure force (LC) and tongue pressure (TP) were evaluated as oral function measurements. Feeding function was evaluated using the Functional Oral Intake Scale (FOIS). QOL was assessed using the European Organization for Research and Treatment of Cancer QOL Questionnaire QLQ-C30 and H&N 35. Measures were evaluated at pre-surgical treatment (PT), and 1 month (1M) and 3 months (3M) after surgery. The change of QOL parameters and relationships between measurements were assessed. RESULTS For QOL assessments, role functioning, fatigue, speech problems, trouble with social eating, trouble with social contact, and opening mouth significantly decreased from PT to 1M, but significantly increased from 1M to 3M. Weight, BMI, SLM, SMM, LC, TP, and FOIS demonstrated significant relationships with QOL from PT to 1M. Meanwhile, from 1M to 3M, weight, BMI, SLM, SMM, LC, and FOIS showed significant relationships with QOL assessments. CONCLUSIONS Both oral function and muscle mass-related measurements significantly affected QOL in HNC patients.

Abstract
INTRODUCTION Tumour aftercare (tac) is an essential tool in oncology. The main aim of these follow ups is to diagnose recurrence and second tumours from the beginning. Tac appointments can create a special environment for patients' further concerns. The purpose of the current study was to evaluate tac of patients diagnosed with OSCC and to investigate their health related quality of life (hrql). MATERIAL AND METHODS A German questionnaire was created by two maxillo-facial surgeons with several years of tac experience. It was handed out to 100 German-speaking OSCC patients during tac. Results were statistically evaluated with SPSS (SPSS version 21.0; SPSS, IBM; Chicago, IL, USA). The inclusion criterion was that diagnosis and surgery were performed at our department and that the patients attended our tac regularly. RESULTS Side effects such as difficulties in speaking and swallowing were evaluated as being significantly higher in cases who were administered adjuvant radiochemotherapy (art) compared with the surgical therapy group (stg) (p = 0.03). Anxiety occurred in 80% of all female patients (p = 0.02), 90% of them with a high psychological strain because of the cancer diagnosis (p = 0.04). DISCUSSION To date, tac is a rare topic in literature. Moreover, only a few trials have focused on hrql in OSCC. A main result of the current study is that during tac, OSCC patients should be regularly questioned about their symptoms and mental state. Further, the need of the majority of OSCC patients for coping therapies can concomitantly be evaluated. CONCLUSION The evaluation of tac is of high relevance. The results of the current study have encouraged us to establish this questionnaire as a routine tool in our tac.

Abstract
Advantages and disadavantages of the three most commonly-used bone grafts for mandibular reconstruction are widely known, but biomechanical experimental studies are rare. We have done loading tests on cadaveric mandibles reconstructed with fibular, iliac crest, and scapular grafts using 3 different osteosynthesis systems to detect and compare their primary stability. Loading tests were done on mandibles with grafts from the fibula and iliac crest and published previously. A 4.5cm paramedian L-type defect was reconstructed with scapula using 2 monocortical non-locking plates, 2 monocortical locking plates, or a single bicortical locking plate/fracture gap in 18 human cadaveric mandibles. These were loaded on to the "Mandibulator" test bench and the movement of fragments in 3 dimensions was assessed and quantified by a PONTOS® optical measurement system. Comparison of the osteosynthesis groups showed that the miniplate was significantly superior to the 6-hole TriLock® plate for both fibular and iliac crest grafts. The fibular graft gave greater stability than the iliac crest and scapular grafts for all 3 osteosynthesis systems. All bony specimens offered sufficient resistance to mechanical stress within the recognised range of biting forces after mandibular reconstruction, independently of the choice of bone graft and osteosynthesis system used. Anatomical and surgical advantages need to be taken into account when choosing a graft. Stability can be maximised with a fibular graft, and further optimised by enlarging the binding area by using the "double barrel" method. Computer simulated experiments could segregate factors that biased results, such as morphological differences among cadavers.

Abstract
OBJECTIVES Since development of oral squamous cell cancer (OSCC) is triggered by various noxa, different variants of the antioxidant glutathione S-transferases (GSTs) can counteract toxic compounds (e.g., tobacco smoke). Because different polymorphisms of GST are known to have an increased sensitivity to carcinogenic agents, the aim of this study was to analyze whether GSTM1 or GSTT1 polymorphisms increase the risk for the development of OSCC. MATERIALS AND METHODS GSTM1 and GSTT1 polymorphism was examined in healthy volunteers (n = 93) and in patients with OSCC (n = 100) by PCR after brush biopsy of oral mucosa. Odds ratio (OR) was calculated to evaluate the risk of oral cancer development. RESULTS GSTM1 and GSTT1 deletion was found in 57% (53/93) and 18% (17/93), respectively, in healthy patients, while the OSCC group showed 57% (57/100) for GSTM1 deletion and 22% (22/100) with a deletion of GSTT1. Odds ratio for GSTM1 polymorphism was 1.00 and for GSTT1 1.26. Comparing smokers and nonsmokers with GSTM1 deletion polymorphism, OR was 4.35, while smokers without GSTM1 deletion showed an OR of 1.45. Adapting these data to the smoking habits of the general population in Germany, the OR was 9.25 for smokers with a GSTM1 deletion and OR 6.68 for smokers without a GSTM1 deletion. In smokers with GSTT1 deletion polymorphism, OR was 1.6 (adapted to the smoking habits of the general population: OR 6.16) and 3.16 (OR 8.56) in smokers without deletion in GSTT1 gene. CONCLUSIONS Analysis of GST-M1 polymorphism in smokers could help to identify patients with a higher risk for the development of oral cancer. CLINICAL RELEVANCE Early detection of OSCC due to a close meshed monitoring program for patients with GST-M1 polymorphism could help to improve the patient outcome. For polymorphism investigations, the oral brush biopsy is a sufficient method to gain DNA material.

Abstract
Treatments used in cancer of the oral cavity have great impact on the physical, psychological and functional state of patients. There has been increasingly interest in evaluating the health-related quality of life using questionnaires among patients treated with oral cancer. Up to our knowledge no review on this theme has incorporated the level of evidence of the single identified studies. The objective of the present study is to determinate results and conclusions about the health-related quality of life of these patients, in view of scientific evidence. In general, the diversity of designs, level of evidence and questionnaires used for their assessment does not affect results, which indicate a decline in the health related quality of life after treatment. This decline is greater when the tumor is large in size, and when radiotherapy is used, though the situation is seen to improve over the span of a year. Questionnaires on health-related quality of life provide concrete information regarding the impact of cancer treatment on patients.

Abstract
BACKGROUND Treatment for metastatic cutaneous head and neck squamous cell carcinoma is usually multimodal and associated with morbidity. This study aimed to evaluate the impact of treatment on patients' quality of life. METHOD Cross-sectional survey of 42 patients (35 men, 7 women) at least 6 months after metastatic cutaneous head and neck squamous cell carcinoma treatment, using two standardised quality of life questionnaires: the Functional Assessment of Cancer Therapy - Head and Neck questionnaire and the Facial Disability Index, with statistical analysis to identify potential predictors of outcome. RESULTS Female gender correlated with significantly lower Facial Disability Index physical function scores (p = 0.017). Alcohol consumption correlated with significantly better scores for Functional Assessment social well-being (p = 0.016), general total score (p = 0.041) and overall total score (p = 0.033), and for Facial Disability Index physical function (p = 0.034). Marital status, education, employment, chemotherapy, time from last treatment, parotidectomy and facial nerve sacrifice did not affect quality of life. The commonest patient complaints were dry mouth (76 per cent), altered voice quality and strength (55 per cent), and physical appearance (45 per cent). CONCLUSION Female gender predicts worse quality of life, while alcohol consumption (versus none) predicted for better quality of life.

Abstract
OBJECTIVES Pain is a major symptom in patients with cancer; however information on head and neck cancer related pain is limited. The aim of this review was to investigate the prevalence of pain and associated factors among patients with HNC. MATERIAL AND METHODS The systematic review used search of MEDLINE, EMBASE and CINAHL databases to December 2011. Cancers of the oral mucosa, oropharynx, hypopharynx and larynx were included in this review with pain as main outcome. The review was restricted to full research reports of observational studies published in English. A checklist was used to assess the quality of selected studies. RESULTS There were 82 studies included in the review and most of them (84%) were conducted in the past ten years. Studies were relatively small, with a median of 80 patients (IQR 44, 154). The quality of reporting was variable. Most studies (77%) used self-administered quality of life questionnaires, where pain was a component of the overall scale. Only 33 studies reported pain prevalence in HNC patients (combined estimate from meta-analysis before (57%, 95% CI 43% - 70%) and after (42%, 95% CI 33% - 50%) treatment. Only 49 studies (60%) considered associated factors, mostly tumour- or treatment-related. CONCLUSIONS The study has shown high levels of pain prevalence and some factors associated with higher levels of pain. There is a need for higher quality studies in a priority area for the care of patients with head and neck cancer.
