RESUMEN

Background: The objective of this study is to provide a structured protocol for the treatment of verrucous carcinoma (VC) based on size, bone invasion, recurrence and whether neck dissection is necessary or not. In addition, the study evaluates the probability of a wrong histopathological diagnosis. Data Sources: A search was conducted in the Cochrane Library, PubMed and Google from January 1962 to October 2022 by using MeSH terms and keywords. Studies reporting treatment modalities for VC and different histopathological diagnoses after excision of the lesion were selected except case reports and review articles. Study Eligibility Criteria: Thirteen articles were selected. Six hundred and thirty cases of VC were treated by surgery, surgery + neck dissection, radiotherapy, chemotherapy and combination therapy. Statistical analysis revealed surgical treatment as a preferred option. Despite being enlarged, the lymph node was negative for metastasis. So, in OVC cases neck dissection adds only unnecessary morbidity to patients. Participants and Interventions: Radiotherapy or chemotherapy can be used to downstage the disease. 23.3% of cases reported wrong histopathology diagnosis. Study Appraisal and Synthesis Methods: Patients treated for squamous cell carcinoma (SCC) will only experience unnecessary morbidity unless the correct diagnosis is made between VC and hybrid VC. Irrespective of size VC does not metastasise until there are no foci of SCC. Conclusions: Surgical excision of T1- and T2-sized lesions can be performed under local anaesthetic as a biopsy procedure. T3 or T4 lesion can be resected with a safe margin. If it comes as hybrid VC or VC with close margin (0.5 cm, <0.5 cm), neck dissection and further margin should be excised as a second procedure respectively.

RESUMEN

Background: The use of dental implants has become a very predictive method of rehabilitation for patients with partial or complete edentulism. It is more challenging to treat the posterior quadrants of the maxillary ridges using dental implants due to their anatomical and physiological characteristics. So to overcome the limitations of other techniques, short implants were introduced recently as a new approach to simplify implant placement in compromised alveolar bone and to prevent possible damage to vital structures. Purpose: This study aims to compare the clinical outcomes of dental implants placed using the osteotomized sinus floor elevation (OSFE) technique side engaging the bony floor of the maxillary sinus (bicortical anchorage) on one side and the conventional technique by split mouth on the other side. Materials and Method: This study included 15 patients. Study participants had dental implants placed on both sides of the mouth at the same time, so one side was implanted according to the test method, while the other side used the control method. Randomization determined which side would be implanted. Conclusion: The OSFE technique provides greater stability to the implant via bicortical anchorage than conventional techniques, which only provide unicortical anchorage.

RESUMEN

Introduction: Clinicians are baffling for reconstruction of small- to medium-sized defects of the oral cavity since time immemorial, each and every flap has its own limitations, ideal flap should be pliable, easily transferrable that can result in a better restoration of form and function of oral mucosa, we have platysma for the same purpose. Aims: We aim to provide surgical technique of the superiorly-based platysma myocutaneous flap with a single neck incision in this study, as well as the flap design, results, and complications associated with age, gender, the recipient site, and the size of the defect. Materials and methods: Study included 20 patients with oral potentially malignant disorders operated under local anaesthesia with wide local excision and reconstruction with platysma myocutaneous flap at a single tertiary care centre. Statistical Analysis: The association between the variables was calculated using Chi-square tests and paired t tests. P < .05 was considered significant. Results: Five cases of dehiscence were found at varied sites and flap viability was significantly influenced by location of skin paddle. In between anterior jugular vein and posterior external jugular vein it was 100% viable while on and posterior to the vein, had skin paddle loss. Significant improvement in mouth opening was also seen in Oral Sub-mucous Fibrosis patients. Conclusion: The platysma flap is a technique sensitive, and its results are promising for the reconstruction of oral defects.

RESUMEN

Purpose: The behavior of trigeminocardiac reflex (TCR) is limited to few case reports only in maxillofacial surgery, especially for temporomandibular joint (TMJ) ankylosis cases. The present study aims to find out the incidence of bradycardia due to TCR during intraoperative forceful mouth opening in TMJ ankylosis patients. Materials and Methods: A prospective, unicentric observational study was conducted selecting those patients who were planned for osteoarthrectomy with interpositional gap arthroplasty under general anesthesia. Sixty cases of TMJ ankylosis were randomly selected from December 2018 to-03-2020. Predictor variables were patient age, gender, and type of ankylosis, and outcome variables were pulse rate, mean arterial blood pressure (MABP), and oxygen saturation level (SPO2). Data were recorded at baseline and during intraoperative mouth opening via heister jaw stretcher. A Chi-square test was used for testing the association between variables. P values were considered statistically significant at <0.05. Results: The sample size of 60 subjects has been divided into two age groups (10-19) years and (20-40) years. The mean standard deviation age of the patients was 18.32 ± 6.81 years. About 63.3% were male. Out of 60 cases, 14 patients developed bradycardia. The frequency of bradycardia was found 23.3%. According to logistic regression analysis, age and type of ankylosis were the significant predictors of bradycardia. Conclusion: We conclude that bradycardia due to TCR in TMJ ankylosis patients is not an uncommon entity. Incidences are more prevalent in the age group of 10-19 years and type IV bony ankylosis. Male had a high incidence of bradycardia though P value was nonsignificant.

RESUMEN

Objective: This systematic review aims for the explanation of possible postoperative complications, efficacy and limitations of Platysma myocutaneous flap (PMF) in patients with oral submucosal fibrosis (OSMF). Method: An electronic search of the literature was undertaken using PubMed, Cochrane Library, clinical trials.gov in the year 2021, using MeSH terms and keywords to identify prospective, retrospective and observational studies, controlled trials as well as case reports over the period 1913 to December 2021, addressing the patients with a mouth opening <25 mm and habit of gutkha chewing. PMFs are used as a form of intervention. Patient follow up period should be mentioned. Results: A total of 5 publications were included. 2 were prospective studies and 3 were case reports with 79 subjects between the ages of 18 and 45. All included studies reported complications in a non-significant way (p-value = 0.870) with positive results as they impact the patient's functional outcome (mouth opening) in a statistically significant manner (p < 0.0001 and 95% CI) with good patient compliance. Conclusion: PMF is rarely used in routine practice due to their technical difficulty and potential complications like venous congestion and necrosis. In this systematic review, the authors provide valuable insight into the causes of complications and the efficacy of PMFs in OSMF patients. In the process of platysma flap harvesting, it is especially important to preserve the skin flap, arterial perforators and arteries, veins in supra and sub-platysmal flap elevation. Aside from proper flap placement and tunnelling, postoperative care is equally important.
