Introduction: Diced cartilage grafts are well-liked, dependable, and simple-to-use techniques for dorsum camouflage in rhinoplasty. Recent research results demonstrate how effectively PRF increases the survivability of diced cartilage in the nasal dorsum and decreases its absorption. In this study, we intend to investigate the effect of fibrin-rich platelets (PRF) on diced cartilage survival in rhinoplasty surgery.

Materials and methods: This clinical trial included people referred to Rasoul Akram Hospital for rhinoplasty between 2020 and 2021. Patients were divided into two groups: Diced Cartilage alone (DC) and Diced Cartilage + PRF (DC+PRF). Cartilage survival was assessed by ultrasound, photography, and nasal examination, and the two groups were compared six months after rhinoplasty. Patients' satisfaction with surgery was also evaluated using the Utrecht questionnaire.

Results: The mean age of the two groups of 20 patients was 29.05 ± 7.02 and 26.65 ± 8.16 years in the DC and DC + PRF groups, respectively (P>0.05). After treatment, the frequency of irregularity on examination and dissatisfaction score was slightly but insignificantly higher in the DC group compared to the DC + PRF group (25% vs. 15% and 12.25 ± 6.45 vs. 10.45 ± 6.74, respectively, and P values>0.05). The total volume decrease, regardless of the injection site, was significant in both groups (P < 0.05), but the magnitude of volume reduction was significantly higher in the DC group compared to the DC + PRF group (-0.060 ± 0.087 vs. - 0.033±0.017, respectively, P<0.05).

Conclusion: PRF may slow down the absorption process of diced cartilage.

Introduction: Secretory carcinoma, previously known as mammary analog secretory carcinoma, is a rare malignancy of salivary glands. It has a diversity of microscopic patterns and is similar to other salivary gland tumors.

Case report: This report presents the case of a 32-year-old female patient with a painless swelling of the upper lip and a history of recent surgery for an immature ovarian teratoma. The microscopic sections revealed a circumscribed neoplasm composed of macrocystic, papillary-cystic, and microcystic patterns with bland vesicular nuclei and vacuolated cytoplasm. Tumoral cells were strongly positive for mammaglobin, SOX10, GATA3, S-100, and vimentin. The diagnosis of salivary gland secretory carcinoma was made. After 22 months, there has been no recurrence.

Conclusions: As secretory carcinoma is a relatively new entity, it is necessary to understand its characteristics. Although the overall incidence of second primary cancer in patients with salivary gland cancers is low, the possibility of its presence in such patients should be considered.

Introduction: Tracheostomy is a life-saving surgical intervention commonly performed in patients requiring prolonged mechanical ventilation. However, the decannulation process is associated with various complications that can affect patient outcomes. This study aimed to assess complications and their management during decannulation in a cohort of tracheostomy patients at a tertiary care hospital, considering the complexities introduced by prior intubation.

Materials and methods: A retrospective cohort study was conducted involving 450 patients who underwent tracheostomy during a stipulated timeframe. Data regarding demographic characteristics, complications, and management strategies during decannulation were analysed. Special attention was given to distinguishing between complications directly related to the tracheostomy procedure and those potentially influenced by previous intubation.

Results: Out of the 450 patients, 250 experienced minor complications such as localized bleeding, oxygen desaturation, and minor infections. Another 40 faced major complications including severe haemorrhage, tracheal damage, and stenosis. Increasing age and tracheostomy duration were identified as significant predictors of complications. Pharmacological treatments, surgical interventions, and respiratory therapy were among the management strategies employed. The differentiation between complications arising from tracheostomy and prior intubation highlighted the need for comprehensive patient evaluation.

Conclusion: Complications associated with decannulation occur frequently with varying severity. Efficient recognition and management of these complications are vital for improving patient outcomes. The study provides important insights into the challenges experienced during the decannulation process and highlights the necessity of considering prior intubation history in the management of tracheostomy decannulation to refine patient care protocols.

Introduction: Fat tympanoplasty is repair of small dry tympanic membrane perforations using fat as graft material. It is a simple office procedure with minimal morbidity and manipulation of the middle ear.

Materials and methods: The present study was a prospective review of 60 patients who underwent fat tympanoplasty over the period of 15 months. In all the patients fat was harvested from ear lobule.

Results: Patients were kept on follow up for 3 months and evaluated for graft uptake and hearing gain. 86.66% closure rate of tympanic membrane defect was achieved. Postoperative air conduction was 29.6 ± 5.3 while air bone gap was 13.2 ± 6.1.

Conclusion: The study concludes that fat plug myringoplasty is a simple, quick, less invasive method to repair small tympanic membrane defects.

Introduction: Meniere's disease is an inner ear disorder not associated with central brain structure involvement. Although the ECochG test has been commonly used to diagnose Meniere's disease recently, it has not demonstrated high sensitivity. Therefore, it is recommended that other complementary tests alongside the ECochG test be used to diagnose Meniere's disease. The SVV test has gained popularity recently for this reason, and in this study, it was decided to use the SVV test in both static and dynamic modes, along with the ECochG test, as a tool for diagnosing Meniere's disease and evaluating its diagnostic features.

Materials and methods: The study was conducted on 53 patients with confirmed unilateral Meniere's disease and a normal group. Means were calculated with a 95% confidence interval for the groups, and the corresponding graphs were plotted. Independent t-tests were used to examine the difference in SVV results between the normal and Meniere's groups. The ROC curve was then used to determine the cutoff point and calculate.

Results: After investigating the cutoff point for the three SVV conditions (tilted towards the lesion), a cutoff point of 2.1 degrees with a sensitivity and specificity of approximately 0.7 was identified as the best condition for distinguishing the Meniere's group from the healthy group.

Conclusion: Finally, based on the findings, it can be concluded that the SVV test has relatively low sensitivity for diagnosing Meniere's disease. Therefore, more than relying solely on its results to identify Meniere's disease is required, and it is suggested that other measures alongside the ECochG and SVV tests be included in future studies for further investigation.

Introduction: Bell's palsy is one of the most concerning complications of the COVID vaccine that has impacted vaccine acceptance among the general population. These vaccines were introduced to provide immunity against the SARS-CoV-2 coronavirus and have been found to be quite effective. Little did we know that Bell's palsy could be one of its serious complications.

Materials and methods: We used various search engines to gather data in the form of a case series and case reports related to patients who were affected by the vaccine and had developed Bell's palsy.

Results: A total of eleven case reports and 4 case series were included in the analysis. The vaccines mentioned in the case reports were Pfizer, Moderna, Sinovac, AstraZeneca, and Janssen, while the case series included Pfizer and Sinovac. The majority of patients were female and aged between 31-40 years. Right-sided laterality was observed in 45.45% of patients, left-sided laterality in 45.45% of patients, and bilateral laterality in 9.1% of patients. Three patients had a history of Bell's palsy or stroke. After treatment, three patients showed partial improvement, six patients fully recovered, and the status of two patients was unknown.

Conclusions: Bell's palsy is a rare complication that can occur after receiving the COVID-19 vaccine. This review aims to increase awareness about this rare adverse event of the vaccine so that it can be properly addressed and managed. Additionally, it will serve as a foundation for future research on the administration of the COVID-19 vaccine.

Introduction: The aim was to assess prevalence of tinnitus, hyperacusis, hearing and balance problems among patients recovered from COVID-19 infection. Self-reported ear and hearing symptoms were compared in three groups comprising: confirmed COVID-19, possible COVID-19, and non-COVID-19.

Materials and methods: 1649 participants completed the survey in this cross-sectional study. The mean age was 34 years and 65% were female. Participants with confirmed and possible COVID-19 were asked if after their infection (compared to the past) they experienced hearing loss, ringing or whistling noises, fullness or blockage in their ears, loudness of the sounds that are normal to other people bother them more (an indication of hyperacusis), dizziness, giddiness, or imbalance.

Results: Among participants with confirmed COVID-19, 16% reported that compared to the past their hearing has decreased, 21.5% noticed tinnitus, 22.5% aural fullness, 26.1% hyperacusis and 17.3% balance problems. Regression models showed that compared to the non-COVID-19 group, participants with confirmed COVID-19 had odds ratios (ORs) of significantly greater than 1 in predicting presence of self-reported symptoms of hearing loss, tinnitus, aural fullness, hyperacusis and balance problems, OR=1.96 (p=0.001), OR=1.63 (p=0.003), OR=1.8 (p<0.001), OR=2.2 (p<0.001), and OR=2.99 (p<0.001), respectively.

Conclusions: There seem to be higher prevalence of self-report symptoms of ear-related problems among individuals with confirmed COVID-19 infection compared to a non-COVID-19 group during the pandemic.

Introduction: Many studies have been done on the use of aloe vera in wound healing, but fewer studies were done on the influence of this material on the reduction of the alar scar. Therefore, we evaluated the effect of a newly made aloe vera cream on alar wound healing after rhinoplasty.

Materials and methods: This was a randomized, double-arm, parallel-group, double-blind controlled trial and was done from June 2021 to February 2022. External wedge resection was done for all patients. The patients were randomly assigned to receive aloe vera cream (n=31) (intervention group) or Face Doux cream (comparison group) (n = 29). A pharmacist prepared the aloe vera cream. The primary outcome measure was the wound scar status which was assessed by two Questionnaires, including the mean Patient Scar Assessment Questionnaire (PSAQ) and Vancouver Scar Scale (VSS). Randomization and Blinding were done.

Results: The mean PSAQ was significantly lower in group A after two weeks (26.9 versus 31.5, P<0.001), after two months (15.7 versus 19.6, P=0.04), and six months follow-up (8.8 versus 11.8, P=0.005). The mean VSS was significantly lower in group A after two weeks (5.6 versus 7.1, P=0.001), after two months (3.5 versus 4.9, P=0.002), and six months (1.2 versus 2.7, P<0.001). Repeated measurement analysis showed that both interventions significantly affected PSAQ and VSS.

Conclusion: Although both interventions had a significant effect on PSAQ and VSS, compared to Face Duox, the topical use of Aloe Vera cream significantly reduced scar formation after alar resection, both statistically and clinically.

Introduction: Upper respiratory tract infections and sinusitis are more prevalent in children than in adults. Unilateral sinusitis is not uncommon disease. Our aim was to analyze the disease characteristics in children with unilateral sinusitis and compare them with those of adults.

Materials and methods: This study included 124 patients with unilateral chronic sinusitis divided according to age into two groups: pediatric group ≤18 years (66 cases) and adult group >18 years (58 cases). The groups were compared in terms of demographic data, side, clinical manifestations and radiological findings.

Results: In pediatric patients, the most common inflammatory pathology was antrochoanal polyps, followed by allergic fungal sinusitis. On the other hand, chronic sinusitis without nasal polyps is the most common in adults, followed by antrochoanal polyps. The mean duration of clinical manifestations before diagnosis in pediatric patients was significantly shorter than that in adults (P=0.001). The most common symptoms in both pediatric and adult patients were anterior nasal discharge and nasal obstruction. Proptosis was significantly higher in pediatric group than in adult group (P=0.015). On computed tomography (CT), the most commonly affected sinus in both pediatric and adult patients was the maxillary sinus followed by the anterior ethmoid sinus. Bone expansion, erosion and involvement of adjacent structures were significantly higher in pediatric patients (P=0.028, 0.027 respectively).

Conclusion: Pediatric patients have a high incidence of antrochoanal polyps and allergic fungal sinusitis as unilateral inflammatory lesions. These lesions require surgical management. Inflammatory paranasal sinus lesions in pediatric patients have a shorter duration of clinical manifestations and a higher incidence of bone erosion and involvement of adjacent structures; therefore, early diagnosis and management prevent complications.

Introduction: Nasopharyngeal Carcinoma (NPC) is among the most common head and neck cancer, significantly affecting the growth of human tumors. Therefore, this study aimed to investigate platelet-to-lymphocyte ratio (PLR) as a measure of inflammation in patients with various stages of NPC.

Materials and methods: This retrospective case-control study was conducted on patients diagnosed with NPC between 2016 and 2020 in Dr. Hasan Sadikin Bandung Hospital, Indonesia. Based on NPC classification criteria, patients were classified into early and advanced groups. Subsequently, the PLR ratio was calculated as the number of platelet divided by the absolute number of lymphocytes in the two groups, and the results were statistically analyzed using Unpaired T-test, Pearson, and Chi-square test.

Results: A total of 102 patients with an age range of 40 to 49 years were included in this study. A slight correlation of 0.272 (P<0.001) was observed between PLR and clinical stage, while NPC patients with PLR value > 188 had a 2.7 times higher risk of advanced stage (RR=2.702).

Conclusion: The PLR was significantly related to the clinical stage of NPC cancer.
