Post-stapedotomy dizziness after applying topical steroid on footplate: A randomized controlled trial.

Background: Otosclerosis is characterized by abnormal bone growth in the otie capsule. Nowadays, stapedotomy is commonly used for otosclerosis treatment. Currently, postoperative dizziness has been associated with stapedotomy. In 1981, intratympanic dexamethasone was utilized to manage inner ear disorders like tinnitus and acute sensorineural hearing loss. However, there is much uncertainty regarding the effect and safety of topical steroid therapy in the middle ear during stapedotomy. In the present study, we assessed the effect of topical steroid therapy during stapedotomy on postoperative dizziness. Methods: Otosclerosis patients eligible for stapedotomy were randomly divided into two groups based on dexamethasone administration or placebo. Audiometric and tympanometry results were observed and recorded for the involved frequencies. The Dizziness Handicap Inventory was used to quantify patient perceptions of dizziness and balance issues. Audiometry and dizziness assessments were repeated at discharge and 4 months after the operation. Results: The study comprised 72 otosclerosis patients undergoing stapedotomy. At discharge, the intervention group showed a significant reduction in the incidence of dizziness compared to the placebo group. However, in the 4-month follow-up after the operation, both groups experienced a decrease in dizziness incidence, with no significant difference between them. There was also no significant difference in audiometric levels between the two groups. Interestingly, the intervention group had a significantly lower need for systemic anti-dizziness drugs after surgery compared to the control group. Conclusion: Topical dexamethasone during stapedotomy effectively minimizes dizziness at discharge and reduces the need for postoperative anti-dizziness medication. Level of evidence: 2.

Poorly differentiated neuroendocrine carcinoma originating in the subglottic larynx: A case report with imm unohistochemical study.

Key Clinical Message: Laryngeal neuroendocrine carcinomas are the most common non-squamous neoplasm of the larynx. Due to the rarity of the tumor, pathological diagnosis should be confirmed by immunohistochemistry. Abstract: Laryngeal neuroendocrine carcinomas (LNECs) are a rare cancer of the head and neck. Few case reports of poorly differentiated neuroendocrine carcinoma originating in the subglottic larynx exist within the literature. In this case, we discuss a 57-year-old patient with a history of four-month hoarseness with a newly diagnosed of poorly differentiated neuroendocrine carcinoma in the subglottic larynx. Treatment and prognosis of the various NEC groups differ, so precise identification requires consideration of the microscopic findings and immunostaining analysis. immunohistochemistry staining demonstrated positive result for cytokeratin 7, synaptophysin, chromogranin, CD 56, with the Ki-67 index of45%. Although surgery is usually the treatment for all tumor types, chemo radiotherapy is recommended for poorly differentiated NECs because surgery is ineffective.

Sudden sensorineural hearing loss after receiving an inactivated viral vaccine, Sinopharm: Two-case report.

The prevalence of Coronavirus Disease 2019 is a global threat. Due to the high mortality rate caused by this disease, the vaccination is mandatory to protect patients against it and reduce the mortality. Rapid development and widespread use of vaccines have raised the possibility of adverse side effects over the course of administration and follow-up. In this study, we investigated an adverse event of sudden sensorineural hearing loss in two patients receiving first dose of Sinopharm, an inactivated viral vaccine. Both patients experienced sudden hearing loss in their left ear some days after receiving the first dose of the Sinopharm and had normal otoscopic examinations in both ears and mild to severe sensorineural hearing loss was reported in the left ear. After imaging evaluation with magnetic resonance imaging which showed no pathologic points. Two patients were treated with prednisolone and valacyclovir. Both patients experienced response and had good prognosis in their follow-up. Our study showed that there is no direct evidence of an association between Coronavirus Disease 2019 vaccination. A viral infection can cause sudden sensorineural hearing loss and should be considered as a possible side effect after vaccination. Although the number of side effects reported in clinical trials has been very low, long-term follow-up of patients is needed to assess the vaccine's safety, given the incidence of these cases.

Schwannoma (neurilemmoma) of tongue: A rare case presentation and review of literature.

It seems that schwannomas of the tongue base originate from branches of the glossopharyngeal, vagus, or hypoglossal nerves. Additionally, complete trans-oral surgical excision is an efficient method to remove them.

The stage of head and neck diagnosed malignancies in COVID-19 outbreak versus before outbreak: A retrospective study.

BACKGROUND: Global COVID-19 pandemic has affected cancer care systems. Recent studies show that the number of cases diagnosed with cancer has drastically decreased compared to the same period before the pandemic. Therefore, we are confronted with delayed diagnosis of critical cancers. AIM: The aim of this study is to investigate whether the stage of known cancers has been affected by delayed diagnosis and to compare the stages of head and neck cancers diagnosed during and before the pandemic. METHODS: The present study was conducted on 132 patients with malignant head and neck tumors referred to the otolaryngology, head and neck cancer department of Taleghani Hospital from 2019 to 2021. The stage of cancers was compared between two groups of patients with head and neck malignancy referred to the Otolaryngology, Head and Neck Department of the Taleghani Hospital before and during the COVID-19 outbreak. RESULTS: The results from tumor (T), nodes (N), and metastases (M) (TNM) staging (p-value = .015) and T score (value = 0.045) showed that the stage of tumor diagnosed in patients during the COVID-19 pandemic significantly increased compared to patients diagnosed with a tumor before pandemic. CONCLUSION: In the present study, it was observed that the early symptoms of malignant head and neck tumors have been neglected by patients during COVID-19 pandemic and resulted in delayed diagnosis. This result may be explained by the fear of COVID-19 infection in patients, which discouraged them from visiting a doctor at healthcare centers.

Extramedullary plasmacytoma of the sphenoid sinus presenting with visual loss: A case report.

A rare case of sphenoid plasmacytoma in a 62-year-old woman who was presented with a frozen eye is reported. It was histopathologically confirmed based on transsphenoidal biopsy. Moreover, initial evaluation ruled out systemic dissemination of the disease and solitary plasmacytoma was diagnosed. Surgical removal of the tumor with complementary radiotherapy was performed as a treatment modality.

Capillary Hemangioma as an Unexpected Pathology in the External Auditory Canal.

INTRODUCTION: Hemangiomas are benign vascular lesions frequently observed in infancy and childhood. CASE REPORT: A 14-year-old boy was referred to the hospital with a left-sided ear canal mass and hearing impairment. Otoscopic examination revealed a mass that occluded the canal. The transcanal surgical excision was performed. The mass was dissected from the skin, no bony erosion was noted intraoperatively, and the skin was returned back properly. The histopathological report demonstrated a capillary hemangioma of the external auditory canal. CONCLUSIONS: Hemangiomas are relatively common in the head and neck, but rarely detected in the external ear canal and tympanic membrane. Hemangioma of the ear canal may be asymptomatic and accidentally observed. Despite the rarity of the mass, it is important to consider them in the differential diagnosis of external auditory canal masses. The computed tomography and magnetic resonance imaging with gadolinium help to reveal the vascular nature of the mass. Complete surgical excision is the treatment of choice.

Schwannoma of the lateral nasal wall: A case report.

Nasal schwannomas account for about 4% of head and neck schwannomas. We report a rare case of lateral nasal wall schwannoma presenting as a nasal mass in a 70-year-old man.

The safety of povidone-iodine solution in tympanoplasty: a randomised, triple-blind, placebo-controlled study.

OBJECTIVE: Nowadays, povidone-iodine is commonly used as a disinfectant in head and neck procedures. The present study investigated the effect of povidone-iodine, which is used as a disinfectant solution in tympanoplasty, on patients' hearing. METHODS: A povidone-iodine solution was used as disinfection in chronic otitis media patients undergoing tympanoplasty. In the intervention group, 5% povidone-iodine, was applied to the external auditory canal and remained there for 10 minutes. In the control group, povidone-iodine was used but not allowed to enter the external auditory canal by inserting cotton wool into the canal. To evaluate the adverse effect of povidone-iodine on hearing, the bone conduction level was compared between groups at baseline and one month after exposure. RESULTS: Bone conduction levels at frequencies 500 Hz, 1 kHz, 2 kHz, 3 kHz, 4 kHz and 8 kHz and mean of bone conduction level in 500 Hz, 1 kHz and 2 kHz were measured and compared respectively between intervention and control group. No significant difference was seen between bone conduction levels of above frequencies and mean frequencies before and one month after surgery. (P-value = 0.321, 0.432, 0.219, 0.489, 0.61, 0.112, 0.324 respectively). CONCLUSIONS: According to the present study, currently available 5% povidone-iodine did not affect hearing and therefore, can be comfortably used for preparation and disinfection in otologic surgeries.

Efficacy of Platelet-Rich Plasma as an Adjuvant Therapy to Endoscopic Sinus Surgery in Anosmia Patients with Sinonasal Polyposis: A Randomized Controlled Clinical Trial.

Background: Treatment of patients with anosmia is a major therapeutic challenge. The present study evaluated the efficacy of platelet-rich plasma (PRP) in the treatment of anosmia in patients with sinonasal polyposis. Methods:In the present clinical trial, atotal of 48 patients with sinonasal polyposis with theIran Smell Identification Test (I-SIT) score of <6 who completed the medical treatment and were observed 3 months after the sinus surgery were included and randomly divided in to 2groups. After endoscopic sinus surgery, the intranasal injection of 1 mL PRP and normal saline was performed in the olfactory region in the intervention and control groups, respectively. Odor function was assessed using the I-SIT at the baseline and at the end of the studyby an independent samples ttest. Results: Based on the findings of the present study, the I-SIT improved in both groups during the follow-up, as it reached from 2.63 ± 2.63 to 5.85 ± 2.46 after oral steroid administration and 18.93 ± 1.14 after surgery in the intervention group and from the baseline of 2.10 ± 2.83 to 5.62 ± 2.99 after receiving standard medical treatment and 18.43 ± 1.36in the control groupafter surgery. Although this improvement was significant in both groups in either time interval (all with p<0.001), there was no significant difference between the 2groups in terms of changes in the I-SIT score (p=0.802). Conclusion: According to the current study, PRP injection showed no short-term effect on the recovery of olfactory function in patients with sinonasal polyposis.

Lip Augmentation Using Post-Auricular Fibroareolar Tissue as a New Autogenous Filler.

BACKGROUND: Augmentation of facial components is an acceptable approach in facial aesthetics. The best filler material and the optimal technique for facial soft tissue augmentation still remain to be determined. This study has assessed the lip augmentation using post-auricular fibroareolar tissue as a new autogenous filler. METHODS: This prospective study enrolled patients who were candidate for lip augmentation. Loose fibroareolar tissue was harvested from post-auricular region and was inserted in the prepared lip pocket. Standard digital photography was used for lip analysis in each patient before and 6 months after surgery (the height and projection of the upper lip and lower lip). RESULTS: At a mean follow-up period of 6 months, average upper and lower lip height increased from 5.27 to 8.72 mm (p<0.001), and the average upper and lower lip projection increased from 3.97 to 7.75 mm (p<0.001). CONCLUSION: Our technique was minimally invasive and a safe method, in which post-auricular loose fibroareolar tissue was applied for lip augmentation with minimum donor site morbidity and long-term results. On the follow-up, all patients were satisfied with the results and no patients required any revision operation. Moreover, the complication rate was negligible.

Laparoscopic removal of a giant middle ureteral stone: A case report and review of literature.

Giant ureteral calculi stones defined as larger than 5 cm in length or circumference. Although many giant ureteral stones have been reported, the laparoscopic removal of these stones is rare. A 45-year-old male patient presented to our clinic with right flank pain and discomfort from 6 months ago. Abdominopelvic computed tomographic scan showed a giant left middle ureteral stone. On the first stage laparoscopic ureter lithotomy was performed with 3 ports and the stone was extracted from 12 mm port successfully. We used transperitoneal laparoscopic approach in the full lateral decubitus position. three trocars were placed: one camera 11-mm port was placed at the level of the umbilicus on the lateral border of the rectus muscle, a 5-mm port was placed in the midline below the umbilicus, and a 12-mm port was at the superior border of the rectus muscle. The extracted stone size was 6.5*1.7 cm with 33 gm in weight. Due to the advantages of laparoscopic ureter lithotomy in giant ureteral stones and its feasibility to perform in a single session, we could suggest this minimally invasive treatment as a first choice in this group of patients.
