Dermatofibrosarcoma protuberans (DFSP) is rare, generally slow growing tumor, originating from dermal stem cell or undifferentiated mesenchymal cell. DFSP primarily occurs on the trunk and proximal extremities, with reported only 10–15% occurring in the head and neck region. There can be varied presentations of DFSP in atypical sites mimicking a benign appearance and history due to which diagnostic dilemmas can occur. The underlying malignancy needs to be unveiled by histopathology and immunohistochemistry which reveals bland spindle cells in sub epithelium arranged in whorled storiform pattern which was CD34+, suggestive of dermatofibrosarcoma protuberans. Surgical excision is the treatment of choice, wherever possible. We herein report two intriguing cases of DFSP in uncommon sites. [ABSTRACT FROM AUTHOR]

Excision of submandibular gland is currently victim in all neck dissections. In this study we intend to estimate the prevalence of submandibular gland involvement in squamous cell oral carcinomas and identify the factors associated with it. This is a single institutional, retrospective observational study conducted from 22 to 2018 to 28 February 2020. 317 patients were included for analysis as per study criteria. The prevalence of involvement of submandibular gland was 3.8%. Increased risk of submandibular gland involvement was associated with involvement of level-Ib nodes (Odds ratio: 13.6, 2.9–63.3, 95% CI and p = < 0.001) and presence of extra-nodal extension (Odds ratio: 67, 8.4–532, 95% CI and p = < 0.001) and perineurial invasion (Odds ratio: 5, 1.6–16.8 and p = 0.003). In oral cancers, especially early stage carcinoma of buccal mucosa, submandibular gland preservation may be feasible in absence of extra-nodal extension and level-Ib involvement.

Reconstructions of the maxillary defect after tumor resection are challenging surgeries. Maxillary reconstructions are done using obturators, locoregional flaps and free tissue transfers. Free flap options available for maxillary reconstruction are radial forearm, anterolateral thigh free flap, free fibular osteocutaneous flap, rectus abdominis myocutaneous flap, scapular, and iliac crest osteomyocutanous free flap etc. This is a single institutional observational study conducted at a tertiary cancer centre in North East India from May 2018 to April 2019. All the reconstructions are done with free tissue transfer. Post-operative outcome was assessed with University of Washington Quality of Life Questionnaire (UW-QOL v4.1). Data was collected from patient records and hospital online reporting system. All data were analysed using SPSS (statistical package for social sciences) version 21. Brown's classification was used to classify maxillary defects in this study. A p value ≤ 0.05 was considered statistically significant. In our study, we included fourteen patients (n = 14), of which anterolateral thigh free flap was used for reconstruction in thirteen cases and in one case free fibular osteocutaneous flap was done. Mean age is 33.36 ± 14 years; there was two flap failure. Flap failure is associated with a statistically significant low swallowing and appearance score (p value is 0.036 for both). The orbital exenteration is associated with low appearance score but it is not statistically significant (p value 0.70), probably due to small sample size in the series. Our early experience of free tissue transfer in maxillary reconstruction is satisfactory in terms of quality of life of the patient as well as the oncological outcome. With positive initial experience in maxillary reconstruction with free flaps large study population will be considered in near future. [ABSTRACT FROM AUTHOR]

Background Approximately 1–2% of all scalp tumours are malignant, but they comprise up to 13% of all malignant cutaneous neoplasms. The current study presents our experience of reconstruction of scalp and forehead for malignant tumours treated at our centre. Methods This is a single institutional observational study conducted at a tertiary cancer centre in North East India. Post-operative outcomes related to quality of life of patients were measured with help of FACE-Q scales. Face-Q –Satisfaction with outcome and FACE-Q- appearance related psychosocial distress scores were analysed. Histograms were used for descriptive statistics. Data were checked for normality using Kolmogorov–Smirnova and Shapiro–Wilk test. For non-normal data Wilcoxon test was used. A p value less than 0.05 was considered as statistically significant at 5% level of significance. Results Mean age of patients was 57.6 ± 14.2 years. The mean defect size was 89.036 ± 81.77 cm2. The mean satisfaction with outcome scores and distress scores at 3-months was 54.9 ± 8.6 and 34.8 ± 8.5 respectively with a statistically significant p value of 0.001.Mean satisfaction scores and psychological distress scores were better at the end of three months when compared to at the time of discharge with a statistical significant p value of < 0.0001. Conclusion Scalp and forehead reconstructions for defects following oncological resections are technically challenging and if chosen carefully with meticulous planning, both local and free tissue transfers give satisfactory outcome in long term follow up. There are lots of reconstruction options for scalp and forehead defects and knowledge of the basic bio-geometry of the each flap is must. [ABSTRACT FROM AUTHOR]

This study was conducted to see the pattern of neck node metastasis in relation to the size of primary tumour in Well-differentiated thyroid cancer. A prospective study on 50 patients was carried out in the Department of Head and Neck Surgery, Dr B. Borooah Cancer Institute from 1st August, 2018 to 31st July, 2019. All new cases who had not previously received treatment were included which were histopathogically proven. Residual and recurrent cases were not taken into account. Most common age-group affected was 21–30 years (24%). It was more common in females (84%). Papillary thyroid cancer has been found to be the most common histological type of WDTC (88%), out of which the classical variant of PTC constitute 72%. 46% of them had tumour size > 4 cm 88% cases had cervical neck node metastases, out of which 72% were unilateral and 16% were bilateral. The commonest level involved was level VI. There is a definite correlation (clinical and histological) between increased involvement of positivity of lymph node in relation to size of the primary tumour in well-differentiated thyroid carcinoma.

Tracheostomy is the primary surgical procedure to overcome acute respiratory distress due to upper airway obstruction. The design of tracheostomy tubes are for management of obstruction usually above the level of the glottis or cricoid cartilage. Infrequently, we come across patients who present with respiratory difficulty due to obstruction at lower levels of the trachea. In such patients, tracheostomy may not alleviate the obstructive symptoms as the limited length of the tube may not bypass the obstruction. There is a dearth of long tracheostomy tubes commercially. They are usually not readily available and costly. We present a method to combine and modify an endotracheal tube and a tracheostomy tube to fashion them into a Long Tracheostomy Tube. We also present two cases where we used the long tracheostomy tubes in an otherwise difficult to manage scenarios. [ABSTRACT FROM AUTHOR]

Tracheostomy is a life-saving procedure done electively or most commonly in emergency basis. In patients with diagnosed case of cancer in upper airway tract they usually require tracheostomy at some point of time during their whole treatment procedure. Patients receiving radiotherapy or chemotherapy or combination of these are at high risk of developing post treatment changes in neck anatomy. Redo tracheostomy due to any reasons in such types of patients is a surgical challenge. The purpose of this article is to share our surgical technique in redo tracheostomy. During a period of two years 39 patients with diagnosed cancer in head neck region underwent redo tracheostomy at the hand of the author. Twenty-six patients were had received chemoradiation for their primary cancer and 6 patients were planned for second surgery due to recurrence disease in oral cavity. Reasons for redo tracheostomy are: sixteen patients were post chemoradiation on follow up with accidental expulsion of tube, 17 patients were recurrence/residual disease and 6 patients were plan for second surgery due to recurrence disease. In 9 cases the surgery was started by other doctor and taken over by the author due to profuse bleeding (5 cases) and failure to localised the trachea (4 cases). Among the 39 patients successful redo tracheostomy was possible in all. Mild surgical emphysema was encountered in 3 patients which was not significant. There was no other complication related to tracheostomy till the patients were discharge from the hospital. When redo tracheostomy is required in a post chemoradiation patients maintaining the proper dissection plane and procedure is important to avoid unnecessary complication intraoperatively.
