RESUMEN
BACKGROUND: Different fibula osteocutaneous free flap (FOCFF) configurations have been described with a double-skin paddle (DSP) to address composite through-and-through oromandibular defects: division of the skin paddle using different perforators (div-FOCFF) or a de-epithelialized DSP FOCFF (deEpi-FOCFF). This study aimed to compare the surgical outcomes using these two methods (deEpi-FOCFF/div-FOCFF). METHODS: Patients who underwent segmental mandibulectomy and reconstruction with a DSP FOCFF between 2011 and 2014 were included. We compared postoperative outcomes of patients undergoing reconstruction with deEpi-FOCFF versus div-FOCFF implementing propensity score matching. RESULTS: Of the 245 patients, 156 cases (78 pairs) were 1:1 matched. Demographic and oncologic variables were comparable between groups. The average age was 57.68 years. A higher number of perforators per flap was evident in the div-FOCFF group (p < 0.001). The deEpi-FOCFF group exhibited a higher total flap loss rate when compared to the div-FOCFF group (15 % versus 5 % p = 0.03). On multivariate analysis, number of perforators per flap (OR 0.31, p = 0.02), using the deEpi-FOCFF (OR 3.88, p = 0.03), and an increased reconstructive time (OR 1.01, p = 0.01) independently affected the likelihood of free flap failure. CONCLUSION: If the number and location of perforators are optimal, div-FOCFF improves reconstructive outcomes for composite oromandibular defects versus the deEpi-FOCFF.

BACKGROUND: Extracapsular spread (ECS) is the extension of cancer cells beyond the lymph node capsule and is a significant prognostic factor in head and neck cancers. This meta-analysis compared the diagnostic accuracy of CT, MRI, PET, and USG in detecting ECS in head and neck cancers. METHODOLOGY: The authors conducted a systematic review and meta-analysis of studies that compared the diagnostic accuracy of CT, MRI, PET, and USG in detecting ECS in head and neck cancers. They included studies that were published between 1990 and December 2023 and that used histopathology as the reference standard for ECS. RESULTS: The pooled sensitivity and specificity of CT scan were 0.63 (95% CI = 0.53-0.73) and 0.85 (95% CI = 0.74-0.91), respectively. The pooled sensitivity and specificity of MRI were 0.83 (95% CI = 0.71-0.90) and 0.85 (95% CI = 0.73-0.92), respectively. The pooled sensitivity and specificity of PET were 0.80 (95% CI = 0.74-0.85) and 0.93 (95% CI = 0.92-0.94), respectively. The pooled sensitivity and specificity of USG were 0.80 (95% CI = 0.68-0.88) and 0.84 (95% CI = 0.74-0.91), respectively. MRI had significantly higher sensitivity than CT scan (p-0.05). The specificity of CT and MRI was not significantly different (p-0.99). PET scan had the highest specificity among all imaging modalities. CONCLUSION: MRI is the most accurate imaging modality for detecting ECS in head and neck cancers. CT scan is a reasonable alternative, but PET scan may be considered when high specificity is required. USG may not add any further benefit in detecting ECS.
RESUMEN
PURPOSE OF REVIEW: There is no clear consensus guideline that specifies the optimum course of treatment for adult head and neck osteosarcoma (HNO) because of its rarity. The review's goal is to examine the most recent research on the presentation, diagnosis, prognosis, and therapy of head and neck osteosarcoma. RECENT FINDINGS: Due to overlapping symptoms with various benign disorders of the lower jaw and midface bone, these patients present with a noticeable delay. The greatest results for these malignancies can be achieved with surgery with sufficient margins. However, it may not be able to achieve sufficient margins in tumours of the midface and skull base, and the significance of adjuvant radiation/chemotherapy needs to be investigated. The use of adjuvant radiation in instances with an advanced stage, poor prognostic indicators, and inadequate resection is supported by evidence. Nonetheless, there are divergent opinions regarding the advantages of chemotherapy in adjuvant and neoadjuvant conditions, and further multicentric randomized control trials are required to provide robust evidence. SUMMARY: Multimodality treatments seem to yield better results for advanced HNO with adverse features and incomplete resections.

There is recent evidence that suggests that there are multiple strains of coronavirus in different parts of the world. Moreover, scientist have noted multiple mutations and postulated that these changes might increase the infective rate of the virus. However literature on varying severity of disease based on these strains is absent. In this meta-analysis, we have made an attempt to correlate the symptoms in different continents with respect to various studied strains of virus. We searched three databases, PubMed, EMBASE and EMCARE to identify studies reporting symptoms of COVID-19. All articles published between December 2019 and May 2020 was included in this meta-analysis. A total of 56 studies consisted of 7310 patients were included in the meta-analysis. Mean age of patients varied from 22 to 69.8 years. The pooled proportion of male patients was 52%. Highest incidence of fever (76%) and cough (56%) was noted in Chinese population. Sore throat (29%) was most common in Asian population. Upper respiratory tract symptom like Rhinorrhoea, Anosmia and dysgeusia (32%, 47% and 39%) were well documented in European population as compared to the other continents. Nausea and diarrhoea were more common in European (17%, 19%) and Australian (12%, 16%) population. Dyspnoea and fatigue were consistently similar in all the continents. We postulate that different mutations in COVID-19 virus may vary its pathogenicity and screening symptoms across all the continents should be not be generalised but continent-specific.

RESUMEN
OBJECTIVES/HYPOTHESIS: The objective of this meta-analysis was to look at the pooled prevalence of symptoms, laboratory tests, and imaging of all COVID-19 infected patients. This will allow better identification of potential COVID-19 patients and take appropriate precautions. STUDY DESIGN: Meta analysis. METHODS: We searched three databases, PubMed, EMBASE, and Ovid to identify studies published between Dec-2019 and May-2020. All studies reporting upper-aerodigestive symptoms of COVID-19 infection were included. The meta-analysis was conducted following meta-analyses of observational studies in epidemiology (MOOSE) guidelines, which have evaluated the pooled prevalence of 14 symptoms and nine laboratory investigations. RESULTS: Based on inclusion criteria, 67 publications consisting of 8302 patients were included. Among adults, the pooled proportion of hypertensive and diabetic patients was 18% and 7%. Cough (53% [0.46-0.61]), anosmia (38% [0.19-0.58]), loss/distortion of taste (31% [0.17-0.45]), and nasal obstruction (26% [0.12-0.39]) were the most common ear, nose & throat (ENT) symptoms. Fever (69% [0.62-0.76]) and fatigue (31% [0.26-0.37]) were the commonest generalized symptoms. C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) were raised in 56% (0.41-0.71) and 49% (0.21-0.77), respectively. Interestingly, lymphopenia (41% [0.30-0.53]) and leucopenia (22% [0.16-0.29]) were more common than lymphocytosis (33% [0.02-0.64]) and leucocytosis (12% [0.09-0.16]). Fever (69% vs. 44%), cough (53% vs. 33%), and dyspnea (20% vs. 4%) were more common in adults as compared to the pediatric population. Diarrhea was more common among the pediatric cases (12%) versus (9%). The pooled estimate of fatality was 4%. CONCLUSIONS: The most commonly experienced ENT symptom was cough followed by anosmia and dysguesia. Raised ESR and CRP with leukopenia and lymphopenia are common laboratory findings. Majority of the infected patients had abnormal computed tomography findings. COVID infection is less severe in pediatric patients. Laryngoscope, 131:1254-1265, 2021.

BACKGROUND: Evidence for performing contralateral neck dissection (CND) of recurrent oral cavity squamous cell cancers (OCSCC) is lacking. MATERIAL AND METHODS: This is a retrospective study of 78 consecutive OCSCC having ipsilateral recurrence recorded over five years. We screened 1658 OCSCC patients and selected those patients who underwent CND as part of treatment for ipsilateral recurrence. RESULTS: The median disease-free interval was 32 months. Incidence of contralateral nodal metastasis (CNM) in recurrent OCSCC was 23.1% and of which 14% were occult. The factor significantly influencing CNM was the depth of invasion (DOI) > 10 mm (p < 0.01). In our study, imaging had suboptimal PPV (33%) while it had high NPV (88%) in diagnosing nodal metastasis in recurrent OCSCC. CONCLUSION: DOI is the most important factor predicting CNM in case of ipsilateral primary recurrence. PET-CECT has a high NPV and contralateral neck should be addressed in case of tumours with higher DOI.

Elective neck dissection (END) is preferred in all treatment naïve patients with invasive oral squamous cell carcinoma (OSCC), including the early stage, node negative cases (T1/T2 N0). Usually the conventional horizontal neck crease incision leads to a faintly visible scar in the neck. However sometimes, the neck scar is hypertrophic and is highly unaesthetic and psychologically distressing to the patient. Retro-auricular hairline approach has been popularized in the Robot assisted neck dissections (RoAND), to avoid easily visible scar in neck crease. We have been using the retro-auricular incision for selective neck dissection in early invasive OSCCs using an assembly of customized retractors as an open approach with only occasional use of endoscopes. This approach to the neck surgery is oncologically safe, reproducible and economical. It is cosmetically superior as the scar of neck dissection is in a less conspicuous area of the face, hidden behind the ear and in the hairline.

The aim of our study was to evaluate the predictive ability of the American Joint Committee Cancer (AJCC) eighth edition (AJCC8) staging system for oral cavity cancers and validate these changes rendering the hypothesis of improving prognostication. We conducted a retrospective study including all oral cavity squamous cell carcinoma patients visiting our tertiary center from 2012 to 2015, staged as per the AJCC seventh edition (AJCC7) and AJCC8 systems. Stage-specific disease-free survival (DFS) and overall survival (OS) were calculated using the Kaplan-Meier method. Concordance index (CI) and Akaike information criterion (AIC) were used to calculate the predictive accuracy of the both systems. The study sample consisted of 863 subjects followed up for a median of 24 months. Buccal mucosa complex (BMC) was the most common site (n = 496). We observed a 25.8% (n = 222) overall upstaging in the eighth edition, significantly seen in early tongue cancers (TCs) (Stage I) and advanced BMC cancers (Stage III). An increase in CI and reduction in AIC scores were indicative of a superior predictive accuracy for the eighth edition in assessing DFS (confidence interval [CI*] = 0.650-0.654; AIC = 3,022-3,014) and OS (CI* = 0.643-0.648; AIC = 2089-2086) across all stages. The accuracy was higher for TCs as compared to BMC. Although not statistically significant, we observed an increase in soft risk factors at higher stages in the eighth edition as compared to its predecessor. We concluded that the AJCC8 has a higher predictive accuracy than the AJCC7 edition, making it a reliable prognosticative tool.

AIM: This study was conducted to assess the disease status of head-and-neck cancer patients visiting the emergency department (ED) and their reason for presentation. We wanted to analyze if these visits could be avoided by incorporating any changes in our clinical practice. METHODS: This was a retrospective analysis of head-and-neck cancer patients attending the ED at a tertiary care cancer center in 2017. Clinical details were noted from the electronic medical records, and descriptive statistics was calculated. The analysis was performed using SPSS version 21 software. RESULTS: Three hundred and thirty-nine head-and-neck cancer patients attended the ED. Of these, 80.2% were males and 48.1% of patients had oral cavity cancers. About 37.2% required palliative care treatment. Nearly, 47.2% of patients presented during their initial evaluation period. About 22.7% required hospital admission and only 14.7% required any sort of emergency intervention. CONCLUSION: Majority of visits to ED could have been avoided with better counseling of the patients and their attendants.
