Full Text Available Objective: To compare sleep-related outcomes in obstructive sleep apnea hypopnea syndrome (OSAHS patients following base of tongue resection via robotic surgery and endoscopic midline glossectomy. Methods: This was a retrospective study. A total of 114 robotic and 37 endoscopic midline glossectomy surgeries were performed between July 2010 and April 2015 as part of single or multilevel surgery. Patients were excluded for indications other than sleep apnea or if complete sleep studies were not obtained. Thus, 45 robotic and 16 endoscopic surgeries were included in the analysis. Results: In the robotic surgery group there were statistically significant improvements in AHI [(44.4 ± 22.6 events/h–(14.0 ± 3.0 events/h, P < 0.001] Epworth Sleepiness Scale (12.3 ± 4.6 to 4.5 ± 2.9, P < 0.001, and O2 nadir (82.0% ± 6.1% to 85.0% ± 5.4%, P < 0.001. In the endoscopic group there were also improvements in AHI (48.7 ± 30.2 to 27.4 ± 31.9, P = 0.06, Epworth Sleepiness Scale (12.6 ± 5.5 to 8.3 ± 4.5, P = 0.08, and O2 nadir (80.2% ± 8.6% to 82.7% ± 6.5%, P = 0.4. Surgical success rate was 75.6% and 56.3% in the robotic and endoscopic groups, respectively. Greater volume of tissue removed was predictive of surgical success in the robotic cases (10.3 vs. 8.6 ml, P = 0.02. Conclusions: Both robotic surgery and endoscopic techniques for tongue base reduction improve objective measures of sleep apnea. Greater success rates may be achieved with robotic surgery compared to traditional methods.

To develop, validate, and study the efficacy of an intraoperative real-time continuous image-guided surgery (RTC-IGS) system for glossectomy. Prospective study. We created a RTC-IGS system and surgical simulator for glossectomy, enabling definition of a surgical target preoperatively, real-time cautery tracking, and display of a surgical plan intraoperatively. System performance was evaluated by a group of otolaryngology residents, fellows, medical students, and staff under a reproducible setting by using realistic tongue phantoms. Evaluators were grouped into a senior and a junior group based on surgical experience, and guided and unguided tumor resections were performed. National Aeronautics and Space Administration Task Load Index (NASA-TLX) scores and a Likert scale were used to measure workloads and impressions of the system, respectively. Efficacy was studied by comparing surgical accuracy, time, collateral damage, and workload between RTC-IGS and non-navigated resections. The senior group performed more accurately (80.9% ± 3.7% vs. 75.2% ± 5.5%, P = .28), required less time (5.0 ± 1.3 minutes vs. 7.3 ± 1.2 minutes, P = .17), and experienced lower workload (43 ± 2.0 vs. 64.4 ± 1.3 NASA-TLX score, P = .08), suggesting a trend of construct validity. Impressions were favorable, with participants reporting the system is a valuable practice tool (4.0/5 ± 0.3) and increases confidence (3.9/5 ± 0.4). Use of RTC-IGS improved both groups' accuracy, with the junior group improving from 64.4% ± 5.4% to 75.2% ± 5.5% (P = .01) and the senior group improving from 76.1% ± 4.5% to 80.9% ± 3.7% (P = .16). We created an RTC-IGS system and surgical simulator and demonstrated a trend of construct validity. Our navigated simulator allows junior trainees to practice glossectomies outside the operating room. In all evaluators, navigation assistance resulted in increased surgical accuracy.

The current study seeks to provide preliminary data regarding this central, adaptive response during tongue motor tasks utilizing functional magnetic resonance imaging (fMRI) before and after glossectomy. Six patients, with confirmed histological diagnoses of oral tongue cancer, underwent fMRI before and 6 months after partial glossectomy. These data were compared to nine healthy controls. All subjects performed three tongue motor tasks during fMRI: tongue tapping (TT), dry swallow (Dry), and wet swallow (Wet). Following surgery, increased activation was subjectively observed in the superior parietal lobule, supplementary motor area, and anterior cingulate. Region of interest (ROI) analysis of the precentral gyrus confirmed increased cortical activity following surgery. In addition, comparisons between pre-surgical scans and controls suggested the dry swallow task was sensitive to elicit tongue-related activation in the precentral gyrus (p ≤ 0.05). The adaptive changes in the cortex following partial glossectomy reflect recruitment of the parietal, frontal, and cingulate cortex during tongue motor tasks. In addition, post-operative activation patterns more closely approximated control levels than the pre-operative scans. Furthermore, the dry swallow task appears most specific to elicit tongue-related cortical activity. (orig.)

Full Text Available Background: The consequences of a diagnosis of head and neck cancer and the impact of treatment have a clear and direct influence on well-being and associated quality of life (QOL in these patients. Aims: To determine the QOL in head and neck cancer patients following a partial glossectomy operation. Design and Setting: Cross-sectional cohort study; Head and Neck Oncology Unit, tertiary referral center. Materials and Methods: 38 patients with partial glossectomy were assessed with the University of Washington head and neck quality of life (UW-QOL scale, version 4. Statistical Analysis: Statistical analysis was performed using the Statistical Package for Social Sciences 10.0 (SPSS Inc, Chicago version III. Information from the scale was correlated using the Mann Whitney test. A P value less than/equal to 0.05 was considered as significant. Results: The mean (sd composite score of the QOL in our series was 73.6 (16.1. The majority (71.8% quoted their QOL as good or very good. Swallowing (n = 16, 47.1%, speech (n = 15, 44.1% and saliva (n = 15, 44.1% were most commonly cited issues over the last 7 days. On the other hand, the groups with reconstruction, neck dissection, complications and radiotherapy demonstrated a significant reduction of quality of life scores (Mann Whitney test, P < 0.05. Conclusion: The composite score and overall QOL as assessed using the UW-QOL scale (version 4 were modestly high in our series of partial glossectomy patients. Swallowing, speech, and saliva are regarded as the most important issues. Stage of the disease, neck dissection, reconstruction, complications, radiotherapy and time since operation were seen to significantly affect domain scores.

Since the tongue is the oral structure responsible for mastication, pronunciation, and swallowing functions, patients who undergo glossectomy can be affected in various aspects of these functions. The vowel /i/ uses the tongue shape, whereas /u/ uses tongue and lip shapes. The purpose of this study is to investigate the morphological changes of the tongue and the adaptation of pronunciation using cine MRI for speech of patients who undergo glossectomy. Twenty-three controls (11 males and 12 females) and 13 patients (eight males and five females) volunteered to participate in the experiment. The patients underwent glossectomy surgery for T1 or T2 lateral lingual tumors. The speech tasks "a souk" and "a geese" were spoken by all subjects providing data for the vowels /u/ and /i/. Cine MRI and speech acoustics were recorded and measured to compare the changes in the tongue with vowel acoustics after surgery. 2D measurements were made of the interlip distance, tongue-palate distance, tongue position (anterior-posterior and superior-inferior), tongue height on the left and right sides, and pharynx size. Vowel formants Fl, F2, and F3 were measured. The patients had significantly lower F2/Fl ratios (F=5.911, p=0.018), and lower F3/F1 ratios that approached significance. This was seen primarily in the /u/ data. Patients had flatter tongue shapes than controls with a greater effect seen in /u/ than /i/. The patients showed complex adaptation motion in order to preserve the acoustic integrity of the vowels, and the tongue modified cavity size relationships to maintain the value of the formant frequencies.

Full Text Available Oral cancer accounts for about 40% of all cancers inflicting the human beings. Those involving the tongue results in mild to severe deficiencies of phonation, deglutition, mastication, and taste depending upon the degree and extent tissues involved. Often rehabilitation of such patient is a challenge for the prosthodontist and involves a careful observation and evaluation of the residual oral function and ways to restore them. This article presents a case report of prosthodontic rehabilitation completely edentulous patient, who underwent partial glossectomy following surgical resection of the squamous cell carcinoma involving left lateral borders of the tongue. An attempt was made to restore the comfort and function of the patient with the help of palatal augmentation prosthesis, with additional assistance through speech therapy and simple oral exercises.

Swallowing dysfunction is related to long-term weight loss and reduced body mass index in patients with head and neck cancer. We describe a 76-y-old woman who had severe sarcopenic dysphagia and atrophy of the reconstructed tongue for 17 mo after subtotal glossectomy due to tongue cancer and lost 14 kg during that period. Upon admission, the patient received diagnoses of malnutrition in the context of social or environmental circumstances with insufficient energy intake, loss of muscle mass, localized fluid accumulation, weight loss, and sarcopenia due to reduced skeletal muscle mass (skeletal muscle index protein intake to 70.3 g/d by supplying sufficient excess energy, and provided physical therapy and dysphagia rehabilitation to improve sarcopenia, atrophy of the reconstructed tongue, and dysphagia. After 20 mo of treatment, she was considered to be no longer malnourished (11 kg weight gain) and without sarcopenia (skeletal muscle index 4.01 cm 2 /m 2 ), and the volume of the reconstructed tongue was increased. Sarcopenia and atrophy of the reconstructed tongue may cause dysphagia after glossectomy due to tongue cancer. Additionally, nutritional support and rehabilitation could improve such dysphagia.

This preliminary study examined whether the type of surgery performed for head and neck lesion was associated perceived chewing ability, objective masticatory function, and oral health-related quality of life (OHRQoL) in patients who required a dento-maxillary prosthesis postoperatively. Thirty-eight patients with a dento-maxillary prosthesis were divided into three groups according to the type of surgery received: marginal mandibulectomy, segmental mandibulectomy with bony reconstruction, or glossectomy. Perceived chewing ability, objective mixing ability, and OHRQoL were evaluated using a food intake questionnaire, color-changeable chewing gum, and the Geriatric Oral Health Assessment Index (GOHAI), respectively. Differences in the scores obtained by the three measures were compared between the surgical groups using the Kruskal-Wallis test, and associations between the scores in each group were analyzed by Spearman's rank correlation analysis. Objective mixing ability was found to be significantly low only in patients who underwent glossectomy. No other measures differed significantly between the surgical groups. Perceived chewing ability and objective mixing ability were significantly associated in the marginal mandibulectomy and glossectomy groups but not in the segmental mandibulectomy group. Furthermore, GOHAI score was significantly associated with perceived chewing ability and objective mixing ability in the marginal mandibulectomy group. Within the limitations of this study, the present findings suggest that the type of surgery received might influence food mixing ability. Associations among food mixing ability, perceived chewing and OHRQoL are not accountable depending on the type of surgery received, indicating the presence of other contributing factors to be considered.

Laser surgery can control intraoperative hemorrhaging and enable lesions to be accurately removed since, unlike an electrotome, it does not effect electrocontractility. It can also reduce postoperative pain and dysfunction. This study investigated the efficacy of laser surgery in recurrent tongue cancer following radiotherapy. Of the total of 105 patients with squamous cell carcinoma of the tongue (T1, T2N0) who underwent radiotherapy at the Department of Oral and Maxillofacial Surgery, Kobe University Graduate School of Medicine, at some point between 1980 and 1998, 24 (22.9%) experienced local recurrence. Sixteen of these patients underwent surgical removal of the tumor. Of these 16 patients, 8 (4 early- and 4 late-stage recurrence) had partial glossectomy by laser surgery. Following laser surgery, 2 (1 early- and 1 late-stage recurrence) of the 8 patients died from neck metastasis and another 2 (early-stage recurrence) died from other diseases. The primary and neck tumors are both under control in 3 (late-stage recurrence) of the remaining 4 patients. Laser surgery for late-stage recurrent tongue cancer following radiotherapy appears to be a suitable treatment, although comprehensive glossectomy with/without radical neck dissection is necessary for early-stage recurrent cases after radiotherapy.

To describe the clinical characteristics, treatments, outcomes, and factors associated with survival time in a cohort of dogs with lingual neoplasia that underwent surgical excision. Retrospective case series. Animals-97 client-owned dogs. Medical records of dogs with a lingual tumor examined between 1995 and 2008 were reviewed. Records were included if a lingual tumor was confirmed by histologic examination and surgical excision of the mass was attempted. Data were recorded and analyzed to identify prognostic factors. Clinical signs were mostly related to the oral cavity. For 93 dogs, marginal excision, subtotal glossectomy, and near-total glossectomy were performed in 35 (38%), 55 (59%), and 3 (3%), respectively. Surgery-related complications were rare, but 27 (28%) dogs had tumor recurrence. The most common histopathologic diagnoses for the 97 dogs were squamous cell carcinoma (31 [32%]) and malignant melanoma (29 [30%]). Eighteen (19%) dogs developed metastatic disease, and the overall median survival time was 483 days. Median survival time was 216 days for dogs with squamous cell carcinoma and 241 days for dogs with malignant melanoma. Dogs with lingual tumors ≥ 2 cm in diameter at diagnosis had a significantly shorter survival time than did dogs with tumors melanoma predominate. A thorough physical examination to identify lingual tumors at an early stage and surgical treatment after tumor identification are recommended because tumor size significantly affected survival time.

Locally advanced cancer of the tongue base: new method of surgical treatment

Full Text Available Introduction. Patients are characterized by locally advanced tumors in 70–80 % of cases at presentation, so possibility of cure and surgical treatment is limited. Total glossectomy, tongue base resection is associated with severe and permanent disability. Such surgical procedures lead to severe dysphagia, alalia and social maladjustment. Enumerated issues motivated us to develop new method of surgical treatment  of locally advanced base of tongue cancer.Objective is to introduce new opportunities of surgical treatment of locally advanced cancer of the tongue base.Materials and methods. Glossectomy is accomplished in 5 patients suffering from tongue cancer and admitted to N.N. Blokhin National Medical Research Center of Oncology. Swallowing and speech is preserved in all 5 cases.Results. The main advantage of the proposed method is that the cut out muscle flap has a different innervation from different cranial nerves involved in the rate of swallowing, so there is not just a mechanical movement of the epiglottis, but also the control of swallowing by the central nervous system. The reduction of injury and operation time in the proposed method is due to the fact that tissues directly contacting with the defect are used to preserve swallowing and speech. The proposed muscle flap has various sources of blood supply, which improves its nutrition and reduces the risk of complications, and healing occurs in a shorter time in comparison with the prototype. All of the above reduces the duration of hospitalization for an average of 7–9 days.Conclusion. The developed surgical technique allows to achieve early rehabilitation; patients are able to breathe effortlessly, swallow and speak. There is no need in permanent tracheostoma and percutaneous endoscopic gastrostomy tube. All patients remains socially active.

Malignant oral cancers do not commonly occur in pregnant women. But when they do, the presence of a foetus and maternal physiological changes complicate and limit the treatment options. Risk benefit assessment and balancing of them are always important. A 33-year-old woman, who was 25 weeks pregnant, presented with a squamous cell carcinoma on her tongue. She was clinically staged II (T2, N0 and M0). Discussions between the patient, surgical teams and obstetricians agreed to continue her pregnancy while managing the tumour. Hemi-glossectomy and ipsilateral neck dissection was performed. Free antero-lateral thigh flap was transferred to reconstruct the tongue defect, successfully. The patient gave birth to a healthy baby afterward. She is tumour free for 6 years. Free flap reconstruction can be an option, even if the patient is pregnant.

Objective: To investigate the different pattern of neck lymph node metastasis, the choice of surgical methods and prognosis in early tongue squamous cell carcinoma. Methods: A total of 157 patients with early oral tongue squamous cell carcinoma were included in this study. Statistical analysis was performed to identify the pattern of lymph node metastasis, to determine the best surgical procedure and to analyze the prognosis. Results: The occurrence of cervical lymph node metastasis rate was 31%(48/157). Neck lymphatic metastasis was significantly related to tumor size ( P= 0.026) and histology differentiation type ( P= 0.022). The rate of metastasis was highest in level Ⅱ [33% (16/48)]. In level Ⅳ, the incidence of lymph node metastasis was 5%(7/157), and there was no skip metastases. The possibility of level Ⅳ metastasis was higher, when level Ⅱ ( P= 0.000) or Ⅲ ( P= 0.000) involved. The differentiation tumor recurrence, neck lymphatic metastasis and adjuvant radiotherapy were prognostic factors ( Psquamous cell carcinoma, simultaneous glossectomy and neck dissection should be performed. Level Ⅳ metastasis rate is extremely low, so supraomohyoid neck dissection is sufficient for most of the time. The histology differentiation type, neck lymphatic metastasis and adjuvant radiotherapy are independent prognostic factors.
