Left-handedness in otolaryngology, who is right?

Objectives: This study aimed to ascertain the prevalence of left-handedness (LH) among otolaryngology-head and neck surgery (ORLHN) practitioners, investigate dexterity's impact on LH trainees, and identify common patterns in their training to improve the training experience. Methods: A web-based survey was distributed anonymously via email to members of the Saudi Otorhinolaryngology Society. The survey targeted ORLHN attending consultants, board-certified registrars, and current residents. It consisted of three sections: the first focused on the experience of attending consultants in training LH individuals, the second investigated common maneuvers employed by rhinologists, and the third explored the experiences and impacts reported by LH trainees. Results: The study included 174 participants, and found a 13.2% LH prevalence among them. Rhinologists showed disparities, with 50% advising trainees to stand on the left side of the bed and use their left hand for the scope, whereas the other half asked otherwise. Additionally, 94.4% of the participants had not encountered any courses specifically tailored for LH trainees. Among LH trainees, 57% and 41% reported difficulties in learning and performing side-specific procedures such as functional endoscopic sinus surgery and endoscopic septoplasty, respectively, often attempting to switch to their nondominant hand, and feeling disadvantaged due to their laterality. Conclusions: Left-handedness presents challenges for both LH trainees and their trainers in surgical specialties, particularly in ORLHN, in which specific positioning and instruments are crucial to gain access to the desired surgical field. Despite these challenges, there is insufficient support for LH individuals. We recommend encouraging LH trainees to openly disclose and discuss their left-handedness, provide them with mentors, establish standardized operating room setups and techniques, supply appropriate instruments, and demonstrate flexibility in accommodating their needs. Level of evidence: Level 5.

Efficacy of povidone-iodine nasal rinse and mouth wash in COVID-19 management: a prospective, randomized pilot clinical trial (povidone-iodine in COVID-19 management).

OBJECTIVES/HYPOTHESIS: To assess the efficacy of 0.23% povidone-iodine (PVP-I) nasal rinses and mouth washes on detectability of the coronavirus disease 2019 (COVID-19) virus and cycle threshold (Ct) values in nasopharyngeal swabs. STUDY DESIGN: This was an open-label, prospective, randomized, placebo-controlled clinical trial. SETTING: The study was conducted in King Saud University Medical City, Riyadh, Saudi Arabia, from August 2021 to July 2022. METHODS: Participants diagnosed with SARS-CoV-2 were randomly assigned to one of three groups, with participants receiving either 0.23% PVP-I, 0.9% normal saline (NS) nasal rinses and mouth washes, or no intervention (control group). Nasopharyngeal swabs were taken 4, 8, 12, and 18 days after the first swab to measure the detectability of the virus and the Ct. RESULTS: A total of 19 participants were involved in this study. The mean viral survival was 9.8, 12, and 12.6 days for the PVP-I, NS, and control groups, respectively, with a statistically significant difference (p = 0.046). The Ct mean values were 23 ± 3.4, 23.5 ± 6.3, and 26.3 ± 5.9 at the time of recruitment and 25.2 ± 3.5, 15 ± 11.7, and 26.9 ± 6.4 after 4 days for the PVP-I, NS, and control groups, respectively. CONCLUSIONS: When used continuously at a concentration of 0.23%, PVP-I showed promising results in terms of decreasing the pandemic burden by reducing the period of infectiousness and viral load. However, the use of PVP-I did not result in significantly different changes in the quality-of-life parameters in recently vaccinated and mild COVID-19 patients.

Cross-cultural modification of the University of Pennsylvania smell identification test for the Saudi Arabian population: Validation and normative values.

OBJECTIVES: To develop a reliable version of the Saudi Arabian-University of Pennsylvania smell identification test (SA-UPSIT) and to establish normative values for both genders. METHODS: This cross-sectional study was carried out on voluntarily recruited normal participants in King Saud University Medical City, Riyadh, Saudi Arabia, from April 2018 to May 2023. Culture-familiar odors were chosen and the kit was translated into Arabic for the study. The test was modified 3 times in 4 versions. Following this, a random sample was collected to carry out a re-test after 6 weeks. RESULTS: A total of 288 subjects participated in the development of the SA-UPSIT across all versions, including 146 females and 142 males. The average age of the participants was 28.4±9.9 years. In the final version, 111 participants scored an average of 34.5±2.5 for the total score, 35±2.3 for females, and 34.1±2.6 for males. The test-retest reliability coefficient was 0.73, indicating acceptable reliability. CONCLUSION: The new changes carried out to the SA-UPSIT increased the average scores and demonstrated good reliability, making it clinically applicable for diagnosing and monitoring olfactory dysfunction.

Abducens Nerve Neuropraxia due to Acute Bacterial Rhinosinusitis: Case Report and Literature Review.

Background: Acute bacterial rhinosinusitis (ABRS) is a common infection of the paranasal sinuses that can lead to complications such as orbital and intracranial extension. The abducens nerve course is adjacent to the sphenoid sinus. Diplopia is rarely the initial presentation of sphenoid sinus pathology. In this article, we present the case of a middle-aged male who presented with diplopia and abducens nerve palsy secondary to ABRS, and we conducted a literature review in search of similar cases. Case Presentation. A 52-year-old male presented with diplopia secondary to ABRS. Imaging revealed the complete opacification of the bilateral sphenoid and frontal sinuses, with the extension of the inflammatory process to the optic nerve and cavernous sinus. The patient underwent a surgical intervention, which revealed a pyocele collection in the opticocarotid recess inside the sphenoid sinuses. After the surgery, the patient received antibiotics and reported a complete recovery. Conclusions: Acute bacterial rhinosinusitis can present with atypical symptoms and lead to serious complications, such as abducens nerve palsy. Early diagnosis, appropriate management, and timely referral to a multidisciplinary team are crucial to preventing residual nerve damage and ensuring favorable outcomes.

Loss of Vision Outcome for Allergic Fungal Sinusitis: Case Report and Literature Review.

Visual loss is a rare manifestation of allergic fungal rhinosinusitis (AFRS). We report a case of an adult male who was diagnosed with AFRS and who presented during the COVID-19 pandemic lockdown with sudden-onset complete vision loss and a lack of recovery after surgical and medical management. We reviewed the literature on reported cases of AFRS complicated by visual loss to identify factors associated with visual outcomes. We found 50 patients who were diagnosed with acute visual loss due to AFRS, with an average age of 28 ± 14 years. Complete and partial recovery after surgical intervention were reported in 17 and 10 cases, respectively. However, the absence of vision improvement was reported in 14 of the cases. Early diagnosis and prompt intervention can return vision back to normal. However, delayed presentation, complete loss of vision, and acute onset of visual loss are associated with worse outcomes.

Does Adenoid Hypertrophy Increase the Risk of Orbital Complication in Children with Acute Sinusitis?

Adenoid hypertrophy (AH) plays a role as a reservoir for bacterial growth and decreases mucociliary clearance which might contribute to the development of an infection. To compare the presence of AH in the pediatric population presenting with orbital complications as a result of ABRS and the control group radiologically. Patients who were diagnosed with OC as a result of ABRS labeled as case group, and the patients who had undergone computed tomography (CT) for indications other than sinonasal diseases were assigned as control group. Both groups were retrospectively reviewed to measure the adenoid, nasopharynx, and adenoid/nasopharynx ratio (ANR) in the axial and mid-sagittal planes. We compared 52 patients from case group to 57 control group. In the CT axial plane, adenoid length was greater in the OC group compared to the control group, with a significant difference (p-value = 0.02) of 14.2 ± 3.5 mm compared to 11.2 ± 7 mm, respectively. The ANRs were 2.9 in the OC group and 2.8 in the control group, with a p-value of 0.089. In the mid-sagittal plane, only the anteroposterior length was significantly greater in the OC group, with a mean of 19.9 ± 5.3 mm compared to 15.2 ± 8.8 mm in the control group (p-value = 0.007). The process of inflammation increased the anteroposterior length of the adenoids. However, the ANR was similar between the two groups, indicating that adenoid hypertrophy is not directly related as a risk factor for OC in pediatric patients with ARBS.

Lymphoepithelial Carcinoma Originated from the Sinonasal Cavity: Case Report and Literature Review.

Background: Sinonasal lymphoepithelial carcinoma (SNLEC) is a rare neoplasm, representing less than 1% of all types of carcinomas and approximately 3% of head and neck tumors. It can affect the nasopharynx due to the rich lymphoid tissue present in this region. Clinical SNLEC presentation varies, ranging from asymptomatic to nonspecific sinonasal symptoms. We report a case of SNLEC and review the literature for SNLEC presentation, diagnosis, management options, and outcomes. Case Presentation. A 38-year-old male, medically free, presented to the emergency department complaining of nasal obstruction, right facial numbness, persistent right-sided headache, intermittent orbital pain, and a history of on/off epistaxis. Imaging showed a destructive mass in the right sphenoid sinus extending to different sinuses and infratemporal fossa. Biopsy confirmed the diagnosis of SNLEC, with immunohistochemistry being positive for Epstein-Barr virus (EBV) and CK8/18. Induction chemotherapy was started with three cycles of cisplatin and gemcitabine, followed by concurrent chemoradiation therapy. Conclusion: SNLEC is rare, with limited reported cases from around the world. It is mostly seen in adults between their fifth and seventh decades with male predominance. SNLEC is diagnosed using imaging, immunohistochemistry, and EBV testing given its strong association with EBV. Owing to the limited cases, there is no standard approach to treating SNLEC. However, most cases managed with radiation and with and without other modalities showed an excellent response in terms of tumor nonrecurrence.

A Rare Nasopharyngeal Adenoid Cystic Carcinoma: Case Report and Literature Review.

BACKGROUND Adenoid cystic carcinoma (ACC) is a malignant tumor that involves the salivary glands and is rarely seen in the nasopharynx. It is characterized by pain, a high rate of recurrence, and poor survival rate and poor prognosis as it tends to invade the perineurium. Due to the ambiguity of patient presentations, most patients present at a late stage, at which point metastasis has already occurred. CASE REPORT The patient in this case report was an otherwise healthy 56-year-old male smoker who presented to the clinic in March 2022 complaining of nasal obstruction, mouth breathing, recurrent epistaxis, headache, and facial pain. He reported significant weight loss in the past 6 months. The nasal scope showed nasopharyngeal fullness and biopsy-confirmed ACC exhibiting tubular, solid, and focal cribriform growth patterns. Further work-up showed an advanced form of nasopharyngeal ACC with intracranial extension and lung metastasis. The patient received concurrent radiotherapy and chemotherapy. After 6 months, the patient reported an improvement in the pain, and repeated images showed regression of the tumor size. CONCLUSIONS ACC is a malignant disease that is rarely seen in the nasopharynx. Currently, the most commonly agreed upon management for resectable ACCs in the literature is through surgical resection with adjuvant radiotherapy. However, most of the reported cases received radiation and chemotherapy due to the difficulty and risk of radical surgical excision of nasopharyngeal malignant tumors. Patients should be followed up to rule out any local recurrence or distant metastasis.

Surgical Approaches and Outcomes of Short Nose Correction: A Descriptive Systematic Review of the Literature.

OBJECTIVES: The purpose of this study is to describe all published techniques of short nose correction released by surgeons over the years and summarize their outcomes in a descriptive systematic review of the literature. PATIENTS AND METHODS: A computerized literature search was conducted using 5 major databases. All original studies discussing correction methods and/or outcomes of shortened noses were included. The risk of bias was evaluated blindly by 2 reviewers, and the data were descriptively presented. The study protocol was recorded in the International Prospective Register of Systematic Reviews. RESULTS: A total of 24 studies including 1450 patients were included. Lengthening of the nose was performed through a cartilage-only graft in 14 studies, whereas bone graft was used in 3 studies. The mean increase in nasal tip projection in 5 reports ranged from 0.05 to 2.2 mm. The mean nasal length before and after rhinoplasty was reported in 8 studies, with a mean increase ranging from 0.28 to 6.2 mm. Regarding surgical complications, 30 patients had implant deviation or migration, 22 patients experienced postoperative infection, and 12 patients required corrective surgery. CONCLUSIONS: Augmentation of a short nose is a challenging surgical procedure for rhinoplasty. There are several techniques for short nose correction; however, it is difficult to evaluate the outcomes in the absence of a standard tool of assessment. Further analytical studies are warranted to fully evaluate surgical techniques.

Current Therapeutic Approaches to Subglottic Stenosis in Patients With GPA: A Systematic Review.

BACKGROUND: The management of subglottic stenosis (SGS) in granulomatosis patients with polyangiitis (GPA) has no clear guidelines. This systematic review aimed to identify different surgical techniques and evaluate the outcomes of applied procedures. METHODS: An electronic search was performed using 3 major databases, CINAHL, PubMed, and Clinical key, to include relevant studies published from the databases from inception through January 2017. All primary studies reporting treatment of SGS in cases with GPA were included. Articles were excluded if not relevant to the research topic or if they were duplicates, review articles, editorials, short comments, unpublished data, conference abstracts, case reports, animal studies, or non-English studies. RESULTS: Thirteen papers were included in our systematic review with a total of 267 cases for the qualitative review Endoscopic approaches showed favorable outcomes with the need to use multiple procedures to achieve remission. The open transcervical approach showed excellent results mainly after failure of other endoscopic techniques. Tracheostomy was necessary for severe respiratory obstruction symptoms. Medical treatment was essential for stabilizing the active disease and therefore may enhance the success rate postoperatively. CONCLUSION: Subglottic stenosis in patients with GPA requires a multidisciplinary approach to provide optimal management regarding disease activity, grade of stenosis, and severity of symptoms.

Intranasal endoscopic identification of the nasal septal L-strut: a cadaveric study.

BACKGROUND: Preserving the L-shaped strut during septoplasty is a crucial step in the prevention of several types of postoperative nasal deformities. In this study, we aimed to identify the intranasal anatomic landmarks to establish reliable and feasible measurements to preserve an adequate L-strut during an endoscopic septoplasty. METHODS: A prospective study was conducted on 20 cadaver heads. Three measurements were studied within each side of the nasal cavity. The dorsal strut (DS) was measured from the dorsal line to the septal dorsum edge. Then, the caudal strut was measured from 2 different landmarks: the axilla of the inferior turbinate (CSIT) and the pyriform aperture (CSP). RESULTS: We examined a total of 40 nasal cavities from 20 cadavers. The DS showed an average length of 15.1 mm (standard deviation [SD], 3.2 mm). The average lengths of the CSIT and CSP were 23.6 (SD, 3.6) mm and 19.4 (SD, 2.7) mm, respectively. CONCLUSION: Suggested landmarks to identify the dorsal and caudal struts in endoscopic septoplasty are the axilla of the middle turbinate and pyriform aperture bone, respectively. The utilization of the inferior turbinate axilla as a caudal strut landmark showed larger variability and would potentially leave excessive caudal cartilage that could be manipulated if deviated.

Effect of transcranial direct current stimulation on the number of smoked cigarettes in tobacco smokers.

BACKGROUND: Recent studies reported that transcranial direct current stimulation (tDCS) applied over the dorsolateral prefrontal cortex (DLPFC) reduced craving and cigarette smoking. We aimed to evaluate whether 3 sessions of tDCS over the DLPFC modulate cigarette smoking which is a critical factor in tobacco smokers. METHODS: In a double-blinded, sham-controlled, parallel experimental study, 22 participants who wished to quit smoking received tDCS with the cathodal over the right DLPFC and anodal over the left DLPFC based on the 10-20 EEG international system (F4, F3) at an intensity of 1.5 mA for 20 minutes during three consecutive days. For sham stimulation, the electrodes placement was the same as for the active stimulation. RESULTS: For the short time interval (8 days after the end of the tDCS regimen), the number of smoked cigarettes was reduced similarly in the active and sham groups (p < 0.001). Also, at the long time-interval (4 months after the end of the tDCS regimen) as compared to pre-tDCS, there was no significant difference in the number of smoked cigarettes in the active (p = 0.806) or the sham (p = 0.573) groups. Overall, there were no statistically significant differences between the active and sham tDCS groups on cigarette smoking. CONCLUSION: These findings suggested that 3 sessions of tDCS over the right and left DLPFC may reduce number of smoked cigarettes for short-time period but might not be significantly more effective than sham to decrease cigarette smoking.

Safety of intranasal corticosteroid sprays during pregnancy: an updated review.

INTRODUCTION: Rhinitis and rhinosinusitis are commonly encountered in pregnant women. Intranasal corticosteroid (INCS) sprays are generally safe and effective in the treatment of these conditions in the general population. However, the use of some of these INCS sprays during pregnancy is still controversial. OBJECTIVE: To review the current literature about the safety of intranasal corticosteroid sprays during pregnancy. METHODOLOGY: Using different search engines, each type of INCS was reviewed separately (triamcinolone, beclomethasone, budesonide, fluticasone propionate, fluticasone furoate, mometasone, and ciclesonide). A total of 51 full-length articles were examined for eligibility. After applying inclusion and exclusion criteria, a total of three articles were reviewed. RESULTS: No significant association with congenital organ malformations has been linked to intranasal use of beclomethasone, budesonide, fluticasone propionate, fluticasone furoate, or mometasone. Intranasal triamcinolone, however, has been found to have a significant association with respiratory tract defects. Data about the safety of intranasal ciclesonide during pregnancy are not available. CONCLUSION: Lacking sufficient clinical trials on the use of intranasal corticosteroid sprays in pregnancy, we suggest that the intranasal use of fluticasone furoate, mometasone, and budesonide is safe if they are used at the recommended therapeutic dose after a proper medical evaluation. Intranasal fluticasone propionate might be a safe option in the absence of other INCS options due to its questionable efficacy during pregnancy. Risk-benefit ratio should always be considered before prescribing any intranasal corticosteroid sprays during pregnancy.

Effect of Smoking on Cognitive Functioning in Young Saudi Adults.

BACKGROUND Smoking is the predominant form of tobacco consumption and is growing worldwide, particularly in the younger generation in the Middle-East. We aimed to determine the effects of tobacco smoking on cognitive functions among young Saudi adults. MATERIAL AND METHODS We recruited a group of cigarette smokers (N=22) and a group of controls (non-smokers) (N=30) from apparently healthy male volunteers aged 18-29 years. Cognitive function was assessed by using the Cambridge Neuropsychological Automated Battery (CANTAB). The cognitive functions outcome variables were the response time (attention-switching task [AST]), and the percentage of correct response (pattern recognition memory [PRM] task). Clinical, demographic, blood markers (brain-derived neurotrophic factor (BDNF) and apolipoprotein E) were assessed between groups. RESULTS The 2 groups were matched for age and educational status. In comparison to the control group, smokers showed significant cognitive impairments in AST-Latency (p=0.001), AST-Congruent (p=0.001), and AST-Incongruent condition (p=0.001). There was not significant difference in BDNF APOE serum level between the 2 groups. CONCLUSIONS These results indicate that attention and alertness were significantly impaired in smokers compared to non-smokers.
