Introduction: This study was designed to differentiate between the impact of the topical nasal spray of corticosteroids, antihistamines, a combination of them, and normal 0.2% saline in treating patients with post-coronavirus disease 2019 (COVID-19) smell dysfunction.

Materials and methods: Patients with hyposmia or anosmia (n = 240), who recently recovered from COVID-19, were enrolled in this trial and were randomly assigned to four parallel groups. Group I (G1) received a combination of topical corticosteroid and antihistamine nasal spray (n = 60). Group II (G2) received topical corticosteroid nasal spray (n = 60). Group III (G3) received antihistamine nasal spray (n = 60). Group IV (G4) received 0.2% normal nasal saline nasal spray (n = 60). The treatments were used in all groups for 3 weeks. The sense of smell was assessed using the butanol threshold and discrimination tests. The smell tests were evaluated weekly for 3 weeks.

Results: The mean age of the patients was 51.9 ± 7.1 years; moreover, 83.8% and 16.2% were male and female, respectively. The results of the smell tests in the first week significantly improved with those in the third week (P< 0.001). The greatest degree of improvement was found in the first group, followed by the second, third, and fourth groups.

Conclusions: The results suggest the ability of combination therapy of corticosteroid and antihistamine nasal spray to manage post-COVID-19 hyposmia or anosmia; however, this combination therapy was not superior to corticosteroid nasal spray. Trial registration ID: UMIN000043537.

Introduction: Generally, glomus tumors are considered tumors of the autonomic system arising from chromaffin cells of the parasympathetic paraganglia of the skull base and neck. Glomus tympanicum is the most common primary tumor of the middle ear cavity and it arises from the paraganglia of the middle ear.

Case report: We present a case of glomus tympanicum presented in a 70-year-old woman, complicated with facial nerve palsy which at first sight was misdiagnosed as cholesteatoma. Patient presented in our clinic because of otorrhea, pulsatile tinnitus and hearing loss in the right ear. However, facial nerve function was good in the first examination (40 days before the surgery). Eventually, she treated successfully with a canal wall down mastoidectomy. Technique had been chosen because of the mass size and the involvement of external auditory canal, after a discussion with the patient.

Conclusions: Although histologically benign, glomus tympanicum is slow growing and destructs adjacent tissues potentially. The two most common complaints are hearing loss (conductive) and pulsatile tinnitus. These neoplasms are more common in women and they can be diagnosed by CT or MRI scan. It is of high importance physicians suspect a glomus tumor when patient 's clinical findings are hearing loss and pulsatile tinnitus and use an intravascular agent in imaging so that the differential diagnosis will be supported.

Introduction: Many ongoing challenges have been applied to reduce the considerable postoperative pain and increase wound healing after tonsillectomy, but they are still not optimally managed. This study applied autologous platelet-rich plasma (PRP) & platelet-rich fibrin glue (PRFG) to reduce pain and increase wound healing.

Materials and methods: PRP & PRFG were prepared from 26 patients' blood. At the end of the tonsillectomy, one tonsillar bed was selected randomly, PRP was injected, PRFG was applied topically on the bed wound, and the other sites were left untreated. The treated and untreated tonsillar beds were compared for pain and wound healing the next day, 3rd day, 6th day, 9th day, and 15th day.

Results: There were no complications during and after the injection. The mean age was 24.76 ±5.54 years. In the treated beds in comparison to untreated beds, pain decreased marginally in 1st day (intervention:4.5±2.54, control:5.53±2.94, P-value=0.18) and 3rd day (intervention:3.92±2.96, control:4.8±2.82, P-value=0.276), and significantly in 6th day (intervention:2.3±2.46, control:3.92±2.6, P-value=0.026), 9th day (intervention:1.26±1.48, control:2.76±2.4, P-value=0.009) and 15th day (intervention:0.73±1.07, control:1.84±2.36, P-value=0.08) after surgery. Healing did not change in 1st day (P-value=1), changed marginally in 3rd day (P-value=0.2), and increased significantly in 6th day (P-value=0.001), 9th day (P-value=0.006), and 15th day (P-value=0.004) after surgery.

Conclusions: Autologous PRP injection & PRFG application offer an effective, safe, and non-invasive method for reducing pain and increasing wound healing after tonsillectomy.

Introduction: Our study aims to evaluate the distribution of laryngopharyngeal reflux (LPR) in patients with sleep-disordered breathing (SDB) via the Reflux Symptom Index (RSI) and to describe the sleep architecture in SDB patients with and without LPR.

Materials and methods: A cross-sectional, descriptive study was conducted. Patients with SDB were identified via the Epworth Sleepiness Scale (ESS) and STOP-BANG questionnaire; they were then screened with the RSI and physical examination for LPR. PSG was performed to evaluate obstructive sleep apnea (OSA).

Results: Of 45 patients, 15 were scored as having LPR via the RSI. Utilizing the Respiratory Disturbance Index (RDI), patients were further classified into four groups: 9 non-LPR with non-OSA SDB, 21 non-LPR with OSA, 4 LPR with non-OSA SDB, and 11 LPR with OSA. The prevalence of LPR was 30.8% in the non-OSA SDB group and 34.4% in the OSA group. All SDB parameters in both groups were similar. SDB patients with high body mass index tended to have LPR and/or OSA. Average ESS scores in the four groups suggested excessive daytime sleepiness, and patients with LPR had higher ESS scores. Regardless of LPR status, SDB patients had a lower percentage of REM sleep and a higher percentage of light sleep.

Conclusions: The incidence of LPR in OSA patients was similar in non-OSA SDB patients. REM sleep percentage decreased in the four groups, with the non-OSA SDB group having the lowest percentage of REM sleep; light sleep percentage increased in the four groups, with the OSA group having the highest percentage of light sleep.

Introduction: Few studies evaluated the treatment of postoperative pain in middle ear surgery.

Materials and methods: We conducted a randomized clinical trial to evaluate the efficacy of dexamethasone in the management of postoperative pain in middle ear surgery. Group G1 received an intravenous injection of 2 ml of physiological saline 30 minutes before the end of the procedure. Group G2 received a 2 ml intravenous solution containing 8 mg of dexamethasone, 30 minutes before the end of the procedure. Pain perception was measured by the Visual analog scale (VAS) every 10 min during the first hour and then every 6 hours during the 24 hours postoperatively. The delay of the first analgesic demand and the consumption of analgesics use during the first 24 hours postoperatively, were recorded.

Results: VAS values were lower in G2at all measurement points during the first hour, as well as the first 24h postoperatively (Mann-Whitney test, P<0.05).The delay of the analgesic request was (0 (0-60) for G1 versus 0 (0-80) for G2, P=0.04, Mann-Whitney test). Morphine was used in 44% of the patients in G1 against 19% for G2 (P = 0.031). There was a significant difference between G1 and G2 in terms of the total dose of morphine consumed (P= 0.028, Mann-Whitney test). Paracetamol demand was lower in group 2 at all points of assessment during the first 24 hours postoperatively.

Conclusions: Intravenous dexamethasone is effective in decreasing pain and analgesic requirement, during the first 24 hours postoperatively, in patients undergoing middle ear surgery.

Introduction: Head and neck is the second most common region for lymphomas. Extranodal lymphomas of the larynx are rare in the pediatric population. Non Hodgkin Lymphoma (NHL) of the larynx is common in the supraglottic region as its rich in lymphoid tissue. They may present with dysphagia, dysphonia, snoring and progressive respiratory distress. Early visualization of the larynx is essential in such cases for appropriate diagnosis to improve the survival rates.

Case report: We present a case of 9 year old boy who presented with a change in voice, snoring and feeding difficulties for one year. Video laryngoscopy revealed globular mass arising from the epiglottis. He underwent excision biopsy and by immunohistochemistry was diagnosed to have diffuse large B cell lymphoma. He was treated with chemotherapy and the child is clinically well in the follow-up, 1 year after the completion of therapy.

Conclusions: Although primary lymphomas of the larynx in children are rare, a high index of clinical suspicion is warranted to avoid diagnostic delays to initiate appropriate management to have better outcomes.

Introduction: Haemangioma or hemangioendothelioma is amongst the commonest developmental, vascular lesions of infancy and childhood. Hemangioendothelioma of the salivary glands, however, is extremely rare. Due to their rarity, they may be misdiagnosed as lymphangiomas or other cystic lesions found more commonly in the region. This may lead to surgical complications including torrential hemorrhage that may have dire consequences for the patient.

Case report: Herein we present the case of a nine-year-old male with a cavernous haemangioma involving the left submandibular gland which was diagnosed on-table due to inconclusive pre-operative radiological and pathological diagnosis. Fortunately, due to meticulous dissection and care the lesion was excised in toto without any significant blood loss.

Conclusions: Haemangioma of the submandibular gland is so uncommon that often it isn't even considered a differential diagnosis for cystic swellings and lesions in this region. Mistaken diagnoses preoperatively may prove disastrous for the patient. Excision of haemangiomas requires planning for hemostasis and blood loss if it occurs. Even minor iatrogenic manipulation of vascular lesions may completely obscure the field due to bleeding, making dissection and recognition of anatomical landmarks very difficult. This is especially dangerous in the submandibular region due to the proximity of various vital vascular and neural elements. A differential of haemangioma should therefore always be considered by surgeons and radiologists alike for lesions with suspicious or indeterminate features, in this region.

Introduction: Palpable thyroid nodules are stated in 4 to 7% of individuals. This study was designed to evaluate the relation of Thyroid Imaging Reporting and Data System (TIRADS) and fine-needle aspiration (FNA) based cytology reports in patients with thyroid nodules.

Materials and methods: In this retrospective cross-sectional study, individuals with thyroid nodules who were selected for ultrasonographic-guided FNA enrolled in this study. Demographic data, radiologic assessment, and cytology report were gathered based on hospital medical records. TIRADS grading of the nodules was assessed for each nodule. Cytology was performed on all samples. Sensitivity and specificity were calculated by comparing cytology with ACR-TIRADS and also cytology with TIRADS 4-5 cut-off point as a radiologic malignant lesion.

Results: 172 patients were studied, 151 of whom were female and 21 were male. The mean age of the patients was 49.46 years. Most of the patients had TIRADS 4 (53.5%) followed by 3 (31.4%), and 5 (11.6%). 151 patients (87.8%) had a benign lesion in cytology. Of them, 118 had colloid nodules. There was a statistically significant relation between TIRADS and cytology (p-value<0.001). Sensitivity, specificity, AUC, and positive and negative predictive value for ACR-TIRADS classification were 76.19%, 47.54%, 0.619, 20.00%, and 92.06%, respectively. These values for cut-off "4-5" classification was 86.36%, 38.00%, 0.622, 16.96%, and 95.00%.

Conclusions: According to the significant concordance between TIRADS and cytology, as shown in the results of our study, it seems that TIRADS could be used to decrease the amount of unnecessary FNA in individuals with thyroid nodules.

Introduction: Bleeding during endoscopic sinus surgery has an unfavorable effect on the surgical field and prolongs the time of surgery. In this study, we assessed the efficacy of topical furosemide on bleeding and the quality of the surgical field during endoscopic sinus surgery.

Materials and methods: In this clinical trial, 76 patients with chronic rhinosinusitis were selected for endoscopic sinus surgery and randomly assigned to two groups, topical furosemide (intervention) and normal saline (control). The intervention group received 20 micrograms of intranasal spray twice daily, and the control group received regular intranasal saline spray, similar to the intervention group. In addition, the quality of the surgical field (scoring by the BOEZAART grading system) and the amount of bleeding during surgeries were measured. All data were analyzed.

Results: In the intervention and control groups, the mean surgical bleeding volume was 187.70± 24.79 and 229.21± 28.18 ml (P <0.001), the mean of Boezaart scale 2 and 3 (P <0.001) and the mean of surgical time were 106.53±14.67 and 126.63 ± 15.42 minutes (P <0.001), respectively. In patients of the intervention group with and without polyps, the mean surgery time was 99.56± 12.15 and 118.84 ±10.03 minutes (P <0.001), and the mean bleeding volume during endoscopic sinus surgery was 176.46 ± 22.58, 208.46 ±12.14 ml (P <0.001) respectively.

Conclusions: Our findings showed that nasal, topical furosemide spray significantly reduced the amount of bleeding during endoscopic sinus surgery and time of the surgery and improved the quality of the surgical field.
