Intraoral Basal Cell Carcinoma of Soft Palate: A Diagnostic Dilemma and Review of Literature.

Basal cell carcinoma is the most common cancer worldwide. Most of basal cell carcinoma can be detected in the early stages and are generally well controlled with local resection. Despite the high incidence of BCC, intramucosal BCC is a very rare clinical entity. We hereby present a rare case report of pigmented BCC on soft palate and review the literature of this entity.

Can Lateral Thoracic Artery Preservation Improve Results in Large PMMC Flaps? - Our Experience of 61 Cases from Northern India.

Introduction: Pectoralis major myo-cutaneous (PMMC) flap continues to be a widely used tool to reconstruct oral cavity defects. But an unreliable and unstable vascular supply can lead to complications like flap loss, Oro-cutaneous fistula and wound dehiscence. Preservation of the lateral thoracic artery (LTA) has been suggested to improve the vascularity of the skin paddle. The present study aspires to compare the complications and flap related outcomes after preserving or sacrificing the LTA while reconstructing oral cavity defects with bi-folded PMMC flap. Materials and Methods: Retrospective analysis of the data of 61 male patients who were reconstructed with bi-folded PMMC flaps between January 2022 and September 2022 was done. 36 patients were reconstructed using a PMMC flap where the LTA was sacrificed, whereas in 25 patients the LTA was preserved. Data was analyzed in terms of patient factors and flap related complications. Results: The overall complication rate including major/minor complications was 44.26% with flap detachment at 22.95% being the commonest complication observed. 13.11% patients developed an Oro-cutaneous fistula and partial and complete flap loss were seen in 9.83% and 4.91% respectively. LTA preservation was significantly associated with only decreased flap detachment rates (p value < 0.05). No significant association was noticed between other flap related complications and LTA preservation. Conclusion: Reconstructing larger defects with a PMMC flap where the LTA is preserved can help improve the vascularity of the flap and decrease various major/minor flap related complications.

Epidemiological and Histopathological Analysis of Head and Neck Cancers in Northern India- A Retrospective Review.

INTRODUCTION: Head and neck malignancies are responsible for 30% of all cancers in India with a dramatic increase in numbers due to widespread tobacco consumption. This study aims to assess the epidemiological and histopathological spectrum of these tumors. MATERIALS AND METHODS: A large retrospective review of 5469 biopsy-proven patients presenting between 2018 and 2022 with head and neck cancers was done. Tumors were analysed for distribution according to sites of presentations, gender, age and histopathological profiles. RESULTS: With a male-to-female ratio of 4.2:1, men constituted 80.80% of the study population. Mean age of presentation in women was 53.5 years, whereas men presented at an earlier age of 47.2 years. Oral cavity was the commonest site involved (59.7% cases) followed by the oropharynx (23.8% cases). Buccal mucosa was the commonest subsite involved with 1112 cases followed by tongue lesions with 1088 cases. Larynx was responsible for 17.04% of cases. All subsites were more commonly affected in men with the highest Male: Female ratio of 8.29:1 seen in larynx. The lowest ratio of 1.02:1 was seen in lesions of the face and scalp. Squamous cell carcinoma (SCC) was the most common histopathological diagnosis encountered in 88.97% of cases followed by basal cell carcinoma which was seen in 2.10% lesions. CONCLUSION: Oral cavity lesions constitute the bulk of head and neck cancer presentations in India. The disease is more prevalent in men overall and men present at a younger age in comparison to women. SCC is the most prominent histopathology encountered in our study.

Predicting recurrence in oral cavity cancers: a review of 116 patients with buccal mucosa carcinoma in northwestern India.

BACKGROUND: Oral cavity cancers, the second most common type in India, are responsible for 10% of the overall cancer burden. With a recurrence rate of 30% to 40% and a 5-year survival rate of 50%, these malignancies account for substantial morbidity and mortality. Despite advances in treatment modalities, survival rates following treatment completion have not improved significantly. The present study aimed to establish specific epidemiological and pathological factors responsible for recurrence after treatment completion in buccal mucosa cancers. METHODS: A retrospective analysis of the data of 116 patients treated for biopsy-proven cancers of the buccal mucosa was undertaken 1 year after treatment completion. Factors such as age, sex, education, lymphovascular invasion, extranodal extension (ENE), perineural invasion, depth of invasion, and pathological margin status were compared between patients who presented with recurrence and those who did not. Statistical significance was set at p< 0.05. RESULTS: Of the 116 patients, 40 (34.5%) developed a recurrent disease within 1 year. The mean age of the study population was 43.3 years, and males constituted 91.4% of the included patients. Ipsilateral buccal mucosa was the commonest site of disease recurrence. Neck node metastasis, ENE, and margins of resection < 5 mm were significantly related to the recurrence of disease. However, surprisingly, lymphovascular invasion, perineural invasion, and depth of invasion > 10 mm did not show statistically significant associations. CONCLUSION: Neck node metastasis, ENE, and margins of resection < 5 mm were the histopathological factors associated with recurrence in cancers of the buccal mucosa.

Reconstructing Small-Medium Sized Oral Cavity Defects- Our Experience with the Versatile Famm Flap.

Background: Restoration of form and function of the oral cavity post resection for oral cavity malignancies is an enormous challenge in head and neck reconstructive surgery. The facial artery musculo-mucosal (FAMM) flap is an unexplored, underutilized yet an extremely versatile option for such defects. In this analysis we review the performance of the FAMM flap used to reconstruct tongue/floor of mouth (FOM) defects following tumor resection. Materials and Methods: In this retrospective analysis, demographic and disease profiles of 15 patients with Tongue and Floor of Mouth carcinomas reconstructed with a FAMM flap between January 2019 to January 2021 were studied. Complications and functional outcomes were analyzed. Results: Fifteen patients (10 men, 5 women) were reconstructed using a FAMM flap. Mean age of the study sample was 46.46 years (28-60 years). One flap was lost due to complete flap necrosis following venous congestion, two other flaps suffered distal tip necrosis. Three patients developed an Oro-cutaneous fistula, with one going on to develop a surgical site infection of the neck wound. Patients reconstructed for FOM defects had an excellent functional outcome. For patients reconstructed for a tongue defect, 33.33% of patients complained of restricted tongue mobility and 44.44% were dissatisfied with the quality of speech post operatively. Conclusion: The versatile FAMM flap is a reliable, easy to harvest and scarless flap. It provides excellent cosmetic and functional results FAMM flap allowing early resumption of normal daily activities making it an ideal option to reconstruct small to medium sized oral cavity defects.

Can a diagnosis of Leiomyosarcoma soft palate be missed in the era of commoner oral carcinomas? - Rare case report and review of literature.

Leiomyosarcomas (LMSs) of the head and neck are an extremely rare entity. Of all smooth muscle tumors, 4%-10% occur in the head and neck and only 0.06% in the oral cavity. Because of its infrequency, it has been associated with both delayed diagnosis and misdiagnosis. Here, we report the clinicopathological findings of a case of primary LMS of the soft palate in a 42-year-old male patient with an emphasis on the judicious use of ancillary diagnostic modalities to arrive at a definitive diagnosis. Intraorally, LMSs present as painless, lobulated, fixed masses of the submucosal tissues in middle-aged or older individuals. The treatment modalities and lymph nodal dissection criteria are dissimilar to more common oral carcinomas. Hence, definitive diagnosis is necessary.

Prosthetic management of a midfacial defect.

Surgical ablation of a large tumor creates a defect which is technically difficult to reconstruct. Radiated tissue bed poses a challenge to reconstruction and is complicated in presence of osteoradionecrosis. This report describes a case of a 62 year old gentleman with oral cancer who underwent surgery and radiotherapy twice. He developed an orocutaneous defect (OCD) following surgery and radiotherapy. Prosthetic rehabilitation of OCD was done. Full facial impression with irreversible hydrocolloid was made and wax sculpture made on the model obtained. Standard laboratory steps were followed for mould fabrication and maxillofacial silicone was used to fabricate the prosthesis. It was retained to the spectacle with silicone adhesives. The silicone facial prosthesis provided to the patient was easy to use, covered the defect and improved the quality of life of the patient.

Role of adjunct use of omega 3 fatty acids in periodontal therapy of periodontitis. A systematic review and meta-analysis.

BACKGROUND: Host modulation therapy has emerged as a new concept for the treatment of periodontal disease. Recently, a lot of research is being done in product containing docosahexaenoic acid (DHA) and eicosapentanoic acid (EPA). Omega-3 PUFA have therapeutic, anti-inflammatory and protective properties. This systematic review analysed the adjunctive use of omega-3 fatty acids in periodontal therapy of periodontitis patients. METHODS: PICO question (patient, intervention, comparison, and outcome) was formed. Keywords were generated and were fed in databases. The databases were Pubmed, Cochrane library and LIVIVO. Studies selected are Randomized clinical trial, clinical studies, and longitudinal studies. Meta -analysis were performed for Pocket depth (PD), Clinical attachment level (CAL), Gingival index (GI) and Plaque Index (PI). Risk of bias was also assessed. RESULTS: On analysis of all the 8 studies at 3 months showed significant effect of omega -3 fatty acid on clinical attachment level (CAL), Pocket depth (PD). There was significant effect of omega-3 fatty acids in 4 studies at 6 months. CONCLUSION: Within the limitation of the review, omega- 3 polyunsaturated fatty acids seems to have a positive effect on periodontal healing following periodontal therapy. Chronic periodontitis patient should be counselled to incorporate omega -3 fatty acid in their diet along with standard periodontal therapy.

To Study the Role of Absolute Lymphocyte Count and RDW in COVID 19 Patients and their Association with Appearance of Symptoms and Severity.

OBJECTIVE: The present study was undertaken to evaluate prognostic relevance of select circulating immune mechanistic biomarkers in COVID-19 positive patients for early identification and categorization of symptomatic patients who would need critical care with consequent adequate and optimal resource allocation and definitive management protocol. MATERIALS AND METHODS: The present retrospective observational study, on 35 symptomatic and 35 asymptomatic patients, was carried out in SMS Medical College and Hospital, Jaipur comparatively assessing epidemiological history, clinical features and laboratory investigations. RESULTS: During the course of study, 35 symptomatic and 35 asymptomatic patients were assessed. All the patients were of Indian ethnicity and had a history of contact with a COVID 19 positive case. Male patients constituted of 67 % of the population. The median age of patients in symptomatic and asymptomatic group was 60 years and 30 years, respectively. Out of the 70 patients studied, 47 (67%) patients recovered and were discharged whereas 23 (32.8 %) succumbed to the disease process. Lymphopenia was observed in 80% of symptomatic patient population, though only 11.5% of asymptomatic patients documented lymphopenia. Among the patients who died of COVID 19 (n=23), lymphopenia was observed in 18 (82%) patients, with moderate lymphopenia present in 13 (59 %) and severe lymphopenia present in 5 (22.7%) patients. Neutrophilia was observed across both category of patients, symptomatic and asymptomatic. Neutrophilia featured prominently in the symptomatic COVID-19 group with a median nadir in ALC of 7 × 109/L as compared to that of 3.8 × 109/L so observed in asymptomatic sample population. Red cell distribution width was slightly raised in both groups with a median RDW of 15.3% in COVID 19 patients which was raised as compared to that observed in normal population (range: 12.8 ± 1.2 %). CONCLUSION: Lymphopenia is an effective and reliable indicator of onset of symptoms and severity of disease in COVID-19 patients. RDW was found to be higher in COVID 19 patients in comparison to normal patients, however it had no significant relationship with appearance of symptoms or severity of the disease.

Variations in Flexural Strength of Heat-polymerized Acrylic Resin after the Usage of Denture Cleansers.

OBJECTIVE: The objective of this study was to evaluate and compare changes in the flexural strength of heat-cured denture base resins when treated using denture cleansers. STUDY DESIGN: A total of 40 specimens with dimension 65 mm length, 10 mm width, and 3 mm thickness were prepared as per ISO 1567 specification. A total of 10 specimens were immersed in distilled water to be used as control. Of the remaining 30 samples, 10 were treated with Clinsodent, 10 with VI-Clean, and 10 with Clanden denture cleansers. Specimens in each group were subjected to three-point flexural load in universal testing machine at a cross-head speed of 5 mm/min. The peak load (N) was recorded and flexural strength was calculated. The findings were analyzed using Kruskal-Wallis analysis of variance and Mann-Whitney test. RESULTS: Heat-cured denture base resin selected for this study showed significant difference in flexural strength after immersion in denture cleansers Clinsodent, VI-Clean, and Clanden solutions, when compared with the control group. CONCLUSION: Findings of this study showed that denture cleansers altered the flexural strength of heat polymerized acrylic resins that endured soaking cycles which simulated 180 days of use. Hence, denture cleansers should be used with caution, once a day after brushing the dentures. It is advisable for patients to follow the manufacturer's instructions.

Prosthetic management of malpositioned implant using custom cast abutment.

Two cases are reported with malpositioned implants. Both the implants were placed 6-7 months back. They had osseointegrated well with the surrounding bone. However, they presented severe facial inclination. Case I was restored with custom cast abutment with an auto polymerizing acrylic gingival veneer. Case II was restored with custom cast UCLA type plastic implant abutment. Ceramic was directly fired on the custom cast abutments. The dual treatment strategy resulted in functional and esthetic restorations despite facial malposition of the implants.
