Interest in Rhinoplasty and Awareness of Postoperative Complications Among Female High School Students in Riyadh, Saudi Arabia.

Background Rhinoplasty and revision rhinoplasty are facial cosmetic operations that have potentially profound psychological implications for an individual.In recent years, rhinoplasty has increased internationally because of body dysmorphic disorders but also social media influence. As with any surgery, rhinoplasty carries risks, and the aim of this study was to explore female high school students' interest in rhinoplasty and their awareness about its postoperative complications in Riyadh, Saudi Arabia. Methods We employed a cross-sectional design for the study, which included 413 female high school students aged 14 to 17 years. Participants signed a consent form, and data were collected through an online survey from September to November 2022. A validated questionnaire tested for reliability was used. The level of knowledge and interest in rhinoplasty was compared with the socio-demographic characteristics of the female students using the chi-squared test. A p-value of 0.05 was considered statistically significant. Results A total of 413 female high school students responded to our survey, and 135 completed questionnaires were received. Nearly half (48.7%) of the students were happy about the current form of their nose. Among the students, 74.3% would not consider undergoing rhinoplasty, and the most common reason was satisfaction with their nose (69.4%). Those who did intend to undergo rhinoplasty (25.7%) were primarily interested in improving their appearance (74.5%). The total mean knowledge score was 6.01 (SD 3.27) out of 12 points, with 61.7% classified as having poor knowledge levels, and the rest (38.3%) were considered as having good awareness. Conclusions In our perception, the number of teenagers wanting rhinoplasty is increasing. Questions about their knowledge level, attitude, and perspective regarding the procedure should be important considerations for the surgeon.

Correction of Alar Base Retraction by Levator Labii Alaeque Nasi Muscle Dissection and Alar Rim Grafting: A Clinical Prospective Study.

Alar base retraction may result in disharmony of nose structures. Although correction of this retraction may play an important role in patient satisfaction, there is a limited number of studies on alar base retraction correction. The aim of this study was to manage alar base retraction with minimal undesirable results. Six patients underwent correction of alar base retraction using dissection of the levator labii alaque nasi muscle with or sometimes without alar rim grafting. Assessment of the defect was done using preoperative and postoperative frontal view photographs of each patient. Comparing the preoperative and postoperative photographs shows a significant improvement in the nasal base asymmetry, and all six patients have aesthetically satisfying results after a 12-month follow-up period. In conclusion, nasal base retraction is a well-known deformity that has been an area of focus in the rhinoplasty field and management of this defect has very promising results.

Cross-Cultural Adaptation, Validation, and Arabic Translation of the Eustachian Tube Dysfunction Questionnaire (ETDQ-7)

Abstract Introduction The Eustachian Tube Dysfunction Patient Questionnaire (ETDQ-7) scale is used to assess the effectiveness of the treatment and to determine the severity of the eustachian tube dysfunction (ETD). There is currently no validated Arabic version of the ETDQ-7. Objectives The aim of the present study is to test the validity and the reliability of a translated Arabic version of the ETDQ-7. Methods A multicenter prospective validation study was conducted in Riyadh, Saudi Arabia. The ETDQ-7 was adapted and translated into Arabic using a standard validation methodology. Fifty-one patients diagnosed with Eustachian tube dysfunction and 45 healthy individuals were enrolled in the study. The known-groups method was used in the validity analysis. The test-retest method, item-total score correlation, and internal consistency analysis were used for the reliability analyses. Result The overall internal consistency of the Arabic ETDQ items was measured using Cronbach α (Cronbach α = 0.803). The average and total ETDQ scores were significantly higher in the ETD group (17.6) than in the control group (9.87) (p < 0.001). The results indicate a good to excellent correlation (> 0.7). The area under the curve for the total ETDQ score was 88.6% (95% confidence interval [CI]: 80.3-96.8%) Conclusion The Arabic version of the ETDQ-7 scale is a valid instrument for evaluating ETD. It can also be used as an important tool for diagnosis, patient follow-up, and treatment management.

Injection Site Pain, Onset and Duration of Action of Botulinum Toxin Reconstituted in Normal Saline With and Without Sodium Bicarbonate: A Prospective, Single Center, Randomized, Double-Blind Interventional Study.

Purpose: This study was designed to investigate the effects of botulinum toxin type A injections diluted with the mixture of sodium bicarbonate and normal saline on pain reduction, onset of action, and duration of action. Methods: This is a prospective, randomized, double-blind clinical study, which included 30 female patients (age >25). The patients were randomized to receive botulinum toxin injections diluted with normal saline and sodium bicarbonate on one side of the face and saline control injections on the other side. Pain severity was assessed using visual analogue scale. The onset and duration of action were recorded according to the patients' subjective opinions after 1 week and 3 months, respectively. Results: Lower pain intensity ratings were observed when botulinum toxin was diluted with 0.05 and 0.1 mL of sodium bicarbonate as compared to saline. Regarding the onset of action, the botulinum toxin injections diluted with saline and 0.1-mL sodium bicarbonate side showed faster response in many patients than other dilutions (P < .001). Both the 0.05-mL and 0.1-mL sodium bicarbonate concentrations showed longer duration effects on patients than other concentrations. Conclusion: The use of sodium bicarbonate and saline in a mixture for the dilution of botulinum toxin can decrease patients' discomfort and provide a faster action with longer duration effects.

Objectif: Cette étude a été conçue pour étudier les effets des injections de toxine botulinique de type A diluées dans un mélange de bicarbonate de sodium et de solution physiologique salée sur l'atténuation de la douleur, ainsi que sur le début d'action et la durée d'action. Méthodologie: Il s'agissait d'une étude clinique prospective menée à répartition aléatoire et à double insu auprès de 30 patientes (âge ≥ 25 ans). Celles-ci ont été réparties aléatoirement pour recevoir des injections de toxine botulinique diluées dans une solution physiologique salée et du bicarbonate de sodium d'un côté du visage et des injections de solution physiologique salée témoins de l'autre côté du visage. L'intensité de la douleur a été évaluée à l'aide d'une échelle visuelle analogique. Le début et la durée de l'action de la toxine ont été consignées d'après la perception subjective des patientes 1 semaine et 3 mois après les injections, respectivement. Résultats: Des scores d'intensité de douleur plus faibles ont été observés lorsque la toxine botulinique était diluée dans 0,05 mL et 0,1 mL de bicarbonate de sodium, par rapport à la dilutions dans une solution physiologique salée seulement. En ce qui concerne le début d'action, les injections de toxine botulinique diluées dans une solution physiologique salée et 0,1 mL de bicarbonate de sodium ont été associées à une réponse plus rapide chez de nombreuses patientes, par rapport aux autres dilutions (p < 001). Les concentrations de bicarbonate de sodium à 0,05 mL et à 0,1 mL ont produit des effets de plus longue durée sur les patientes que les autres concentrations. Conclusion: L'utilisation du bicarbonate de sodium et d'une solution physiologique salée dans un mélange pour dilution de la toxine botulinique pourrait diminuer la gêne des patientes, ainsi qu'offrir un début d'action plus rapide et des effets de plus longue durée.

Antrochoanal Polyp in Anterior Nasal Cavity: A Case Report.

We report a case of antrochoanal polyp, which has unusual presentation according to the location of the polyp in a 15-year-female patient. The patient came complaining of nasal obstruction, headache, and postnasal drip for a two-week period. The antrochoanal polyp measured 2.5 x 2 cm in the left maxillary sinus and extended to the anterior part of the nasal cavity. CT imaging demonstrated a total opacified left maxillary sinus, maxillary ostium with widening of the left maxillary ostium by polypoid mucosal thickening suggesting an antrochoanal polyp obstructing the left anterior nasal cavity. This case is reported as there are not many articles in world literature describing an antrochoanal polyp presented in the anterior nasal cavity.

Concha Bullosa of the Inferior Turbinate: Report of Two Cases.

Concha bullosa (CB) is defined as pneumatization and the presence of air cells within the nasal turbinates. Inferior concha bullosa (ICB) is a rare anatomical variation of the lateral nasal wall, with only a handful of case reports published in the literature to date. In this article, we present two additional cases of ICB and a review of the literature regarding this rare anatomical variation.

The Nasal Tip Rotation After Primary Rhinoplasty Using Columellar Strut Graft.

OBJECTIVE:  In this study, we aimed to investigate the degree of nasal tip rotation three months after rhinoplasty using columellar strut graft. METHODS:  Using photographs of 25 patients who underwent rhinoplasty, we prospectively analyzed nasal tip rotation before, during, and after three months of the surgery. Columellar strut graft was used for all patients for tip support. Standardized left profile images were taken. For evaluation of tip rotation, the nasolabial angle was measured. The results were statistically compared, and a p value less than 0.05 was considered statistically significant. RESULTS:  The mean preoperative nasolabial angle (NLA) for the entire group was 91.44°, and the directly postoperative angle measured 108.84°. The mean of postoperative nasolabial angles measured at three-month follow-up was 97.2°. The preoperative, directly postoperative, and three-month postoperative nasolabial angles were all recorded. CONCLUSION:  Considering the results of this study, a postoperative nasolabial angle is increased compared to preoperative angle. However, an occasional dropping of the angle might be seen in following months, which can be linked to several factors.

Postoperative malodorous smell in open septorhinoplasty: the effect of intradomal suturing with mucosal release.

PURPOSE: The aim of this study was to test a mucosal release method for decreasing the occurrence of malodourous smells after septorhinoplasty by preventing formation of debris pockets after surgery. METHODS: This study included 50 adult patients from 18 to 45 years of age who underwent open septorhinoplasty from January to May 2019. Patients were divided into two groups. The first group had intradomal (transdomal) sutures without submucosal release, while the second group had mucosal release. All patients had scheduled post-op visits at 1, 2, 4, and 8 weeks and 6 months. RESULTS: The overall postoperative rate of malodorous smell in both mucosal release and non-mucosal release patients at 2 weeks, 8 weeks and 6 months was 43.1%, 31.4% and 5.9%, respectively. Patients 36-45 years of age had a higher rate of postoperative malodorous smell with 55.6% at 2 weeks, decreasing to 33.3% at 8 weeks, and to less than 1% at 6 months. At 2 weeks after surgery, only 20% of the mucosal release group reported a malodorous smell compared to 65.4% in the non-mucosal release group. The rate was 8% at 8 weeks, and less than 1% at 6 months in the mucosal release group compared to 53.8% at 8 weeks and 11.5% at 6 months in the non-mucosal release group. CONCLUSIONS: Utilizing absorbable polydioxanone sutures and releasing the vestibular mucosa of the LLC significantly reduced the rate of postoperative malodorous smell for septorhinoplasty patients with intradomal (transdomal) single-dome suturing.

Recurrence Pattern and Complication Rate of Allergic Fungal Sinusitis: A 10-Year Tertiary Center Experience.

BACKGROUND: Allergic fungal rhinosinusitis is a noninvasive form of highly recurrent chronic rhinosinusitis. Despite the advancement in medical and surgical strategies, recurrence in AFRS in general poses another challenging problem with reported incidence that eventually can reach more than 60%. Recognition and understanding the pattern of disease recurrence will lead to greater understanding of the disease response in our population. METHOD: A retrospective cohort study was performed in King Abdulaziz Medical City in Riyadh, Saudi Arabia. All patients diagnosed with chronic rhinosinusitis and underwent functional endoscopic sinus surgery from the period of January 2006 to December 2016 were reviewed. RESULTS: 28 patients were found to have AFRS based on clinical, radiological, and microscopic examination suggestive of allergic fungal rhinosinusitis. Among these patients, 53% of them were female and 46% were male. The age ranged from 13 to 55 years, with a mean age of 31.57 years. 28.57% of the patients presented with recurrent allergic fungal sinusitis. The duration between the surgery and symptoms recurrence was around one year. Male and female patients had similar recurrence rate (50%). At first visit, 95% of the patients with nonrecurrent disease presented with nasal obstruction compared to 87.5% of the patients with recurrent disease. On the other hand, patients with recurrent disease had more nasal discharge (87.5%), postnasal drip (37.5%), facial pressure/pain (50%), headache (50%), nasal polyposis (87.5%), hypertrophy of inferior turbinate (37.5%), and proptosis (12.5%). Nasal obstruction (87.5%) and nasal polyps (87.5%) were the most common presenting symptoms for the disease recurrence. The pattern of disease recurrence in the previously unilateral disease was 18% ipsilateral and 27% bilateral. For the patients who had bilateral disease formerly, 17% (n = 3) of them had recurrent bilateral disease. CONCLUSION: Allergic fungal rhinosinusitis is a distinct clinical entity. A high recurrence rate is a pathognomonic feature of the disease, despite all the development in medical and surgical trials. This study demonstrated that recurrence rate is lower in our population. However, more studies with a greater number of patients are needed in the future to clearly recognize the pattern of recurrence in patients with AFRS.

Social Media Impact on Aesthetic Procedures Among Females in Riyadh, Saudi Arabia.

Aesthetic procedures represent one of the most commonly performed procedures in the medical field. Such procedures have been growing in popularity. Social media is a term used to describe electronic platforms that promote the dissemination of information to targeted users. These platforms play a critical role in promoting aesthetic procedures. Objective The objective of this study was to assess the impact of social media on aesthetic procedures among the female population in Riyadh, Saudi Arabia. Methods A cross-sectional study was performed. A validated online questionnaire, consisting of 26 questions, was distributed among females visiting the facial plastic clinic at King Abdulaziz Medical City, in Riyadh, Saudi Arabia. Results Out of 1449 participants, 81% were aged between 25 and 34 years. The majority (78.8%) were aware of the complications that may follow aesthetic procedures. The decision to undergo such procedures was affected by the price in 77%. Overall, 97% thought that cosmetic specialized accounts on social media are helpful, yet 77.8% believed that such accounts do not provide sufficient information. The influence of social media upon participants was 68%; 31.9% claimed that social media had no influence. Instagram was the most influential application followed by Snapchat and then Twitter; 50% of the participants routinely apply Snapchat filters and 42% decided to undergo facial changes after applying Snapchat filters. Conclusion Social media is an important source of information with Instagram being the most influential platform. Facial filters have led to an increase in the number of aesthetic procedures carried out.

Comparing the Health Burden of Living With Nasal Deformity in Actual Patients and Healthy Individuals: A Utility Outcomes Score Assessment.

BACKGROUND: Rhinoplasty is a one of the most commonly performed facial surgery aiming at restoring facial aesthetics and improving quality of life. Utility outcome scores are modern, and emerging tools are used to evaluate the burden of a health state on individuals. The study aims to evaluate the impact of living with nasal deformity among real patients and healthy individuals using utility outcome scores. METHODS: A cross-sectional study was conducted at Otolaryngology and Plastic Surgery clinics in a tertiary center. Healthy individuals were recruited from public facilities. A case scenario was developed to reflect an imaginary patient (Nora) with a functional and aesthetic nasal deformity and distributed to participants. Three utility outcomes scores were used: visual analog scale (VAS), time trade-off (TTO), and standard gambling (SG). RESULTS: A total of 407 adult participants were included. Most participants were female (52%). Healthy individuals comprised 71%, and actual patients comprised 29%. Mean VAS score was 0.77 (ie, participants scored Nora's health state as 77%), TTO score was 0.87 (ie, participants were willing to sacrifice 4 years to have Nora's condition corrected), and SD score was 0.91 (ie, participants were willing to take a 9% risk of death to have Nora's condition corrected). Scores differed among actual patients and healthy individuals (P < 0.0001 for VAS and TTO, P = 0.02 for SG). CONCLUSION: Living with a nasal deformity has a significant impact on quality of life. Both patients and healthy individuals are willing to trade a significant number of years to get the condition corrected.

Acute profound sensorineural hearing loss as the initial manifestation of Hairy Cell Leukemia, Case Report and literature review.

INTRODUCTION: Hematologic diseases are rarely present with sudden hearing loss as an initial symptom. Although the precise cause of sudden sensorineural hearing loss has not been identified, several pathophysiological mechanisms have been proposed. However, a variety of hematologic diseases are among the causes of sudden onset deafness. This article represents the first reported case of Hairy cell leukemia (HCL) which presented with acute unilateral profound sensorineural hearing loss as an inital mainfestation. PRESENTATION OF CASE: A 41-year-old man presented with unilateral sudden hearing loss for one day's duration was found to have HCL during a worked up for his hearing loss. The disease worsened, and there was no improvement in his hearing. DISCUSSION: Sudden sensorineural hearing loss can rarely be seen as a paraneoplastic occurrence.Very few cases have been reported in the literature. It has been reported as a presenting symptom of leukemia in numerous clinical and histopathological reports concerning the hearing loss in hematologic diseases. Our case is an example of such a rare incidence. CONCLUSION: The purpose of this study is to draw physicians' attention to the possible association between acute sensorineural hearing loss to HCL, and to highlights permanent deafness as a complication secondary to HCL. Furthermore, it is important to increase awareness on early diagnosis and treatment that may improve treatment outcomes.

Impact of neoadjuvant radiation on margins for non-squamous cell carcinoma sinonasal malignancies.

OBJECTIVES/HYPOTHESIS: Treatment of non-squamous cell carcinoma sinonasal malignancies (NSCCSMs) typically involves surgery and radiotherapy (RT), but optimal sequencing remains controversial. STUDY DESIGN: Retrospective chart review. METHODS: Patients with NSCCSM treated with combined surgery and RT between 2000 and 2011 were identified. Margin control, overall survival, disease-free survival, local recurrence-free survival, and regional recurrence-free survival were compared between neoadjuvant and adjuvant RT groups. RESULTS: Eight-four patients were included (23 neoadjuvant and 61 adjuvant RT). A higher proportion of patients receiving neoadjuvant RT achieved negative/close resection margins compared to those receiving adjuvant RT (83% vs. 41%, P = .003). Multivariable analysis also showed that neoadjuvant RT was associated with an 81% decreased odds of positive margins odds ratio: 0.19, 95% confidence interval: 0.05-0.77, P = .02). CONCLUSIONS: Neoadjuvant RT may be associated with improved margin status among patients with NSCCSM treated with surgery and RT. Future prospective studies with larger, more homogeneous populations are needed to clarify optimal treatment strategies. LEVEL OF EVIDENCE: 4 Laryngoscope, 128:2796-2803, 2018.

Aggressive ossifying fibroma of right ethmoidal sinus: A case report.

BACKGROUND: Ossifying fibroma is a rare benign fibro-osseous lesion seen in the bones of the head and neck area. It is mostly found in the mandible followed by the maxilla and rarely in the paranasal sinuses along with the orbit and skull bones. CASE PRESENTATION: A 30-year-old male patient presented with headache and incidental finding of a right ethmoidal sinus ossifying fibroma by paranasal-sinuses CT scan and MRI of the face. A flexible fiber-optic nasal endoscopy examination revealed a right side fullness. A non-contrasted CT scan of the paranasal sinus showed hyperdense lesion at the right ethmoid air cells. Functional endoscopic sinus surgery was performed and multiple nasal-mass biopsies were taken which showed fibro-osseous lesion most consistent with aggressive ossifying fibroma. Later, a near total resection of skull base tumor by endoscopic surgery was done and patient was discharged next day in a good condition. CONCLUSION: Ossifying fibroma is a rare lesion found in the head and neck area and it is unusual to be found in the paranasal sinuses. Thus crucial attention to the clinical, radiographical and histopathological examination should be taken for more accurate diagnosis and thus appropriate management.

Endoscopic Endonasal Repair of Spontaneous and Traumatic Cerebrospinal Fluid Rhinorrhea: A Review and Local Experience.

This article presents an overview of endoscopic endonasal repair of cerebrospinal fluid (CSF) rhinorrhea. In recent years, endoscopic repair has become the standard of care for managing this condition, because it gradually replaces the traditional open transcranial approach. Discussion includes the etiologic classification of CSF rhinorrhea, management paradigm for each category, diagnosis algorithm, comprehensive description of the surgical technique, and an updated review of the literature regarding the safety and efficacy of this procedure. In addition, the authors present their experience, including 2 surgical videos demonstrating endoscopic repair of CSF rhinorrhea in 2 distinct clinical scenarios.

Silver nitrate mimicking a foreign body in the pharyngeal mucosal space.

Silver nitrate is sometimes used as a means of chemical cauterization for control of minor bleeding and management of hypergranulation tissue following bedside head and neck procedures. There are only few reports available on the imaging appearance of silver nitrate and its potential to mimic a foreign body. We report a case of a patient presenting with dysphagia, odynophagia, and fever following dental work who had a peritonsillar incision and drainage for treatment of a deep neck space infection. During the procedure, silver nitrate was applied to halt the bleeding. Patient was subsequently transferred to another institution. Since the patient was not showing significant clinical improvement on antibiotic therapy, a computed tomography (CT) scan was performed demonstrating a hyperdense structure lodged in the pharyngeal mucosal space in the oropharynx and soft palate that was mistaken for a foreign body such as bone. Silver nitrate can have density similar to bone but does not have the normal architecture of bone with cortex and marrow on CT. Familiarity with the appearance of silver nitrate on CT, lack of bone architecture, and proper documentation and communication of the use of silver nitrate to the consultant radiologist and medical personnel could help avoid misdiagnosis and potentially unnecessary surgical exploration.

Hemorrhagic Hairy Polyp Causing Velopharyngeal Dysfunction in a Newborn.

Velopharyngeal dysfunction (VPD) can be secondary to anatomic, neurologic, or functional maldevelopment in the pediatric population. We present a case of transient VPD after the removal of a voluminous oropharyngeal hairy polyp in a newborn with an intact palate. This report sensitizes physicians, speech-language pathologists, and occupational therapists not only to the repercussions of oropharyngeal congenital masses, such as hairy polyps, on the feeding mechanisms of a newborn but also to the possibility of conservative management.

Evaluating the timing of injection laryngoplasty for vocal fold paralysis in an attempt to avoid future type 1 thyroplasty.

OBJECTIVES: To determine whether immediate (less than 3 months from time of nerve injury), early (from 3 to 6 months from time of nerve injury) or late (more than 6 months from time of nerve injury) vocal fold injection influences the long-term outcomes for patients with permanent unilateral vocal fold paralysis. METHODS: A total of 250 patients with documented unilateral vocal fold paralysis were identified in this retrospective chart review. 66 patients met the inclusion criteria, having undergone awake trancervical injection with gelfoam™, collagen, perlane™ or a combination. Patients with documented recovery of vocal fold mobility, or patients with less than one year of follow-up after the onset of paralysis were excluded. Patients were stratified into immediate (<3 months), early (3-6 months) and late (>6 months) groups denoting the time from suspected injury to injection. The need for open surgery as determined by a persistently immobile vocal fold with insufficient glottic closure following injection was the primary outcome. RESULTS: 1 out of 21 (4.8%) in the immediate group, 2 out of 17 (11.8%) in the early group and 20 out of 28 (71.4%) in the late group required type 1 thyroplasty procedures to restore glottic competence. There was significance when comparing late injection to both early and immediate injection (p < 0.001). No statistically significant differences were seen when comparing the number of injections needed to restore glottic competence. CONCLUSIONS: This 10-year longitudinal assessment revealed that early medialization of a permanent paralyzed, abducted vocal fold with a temporary material appears to diminish the likelihood of requiring permanent laryngeal framework surgery.

Coblation technique as an alternative treatment modality for oral lymphangioma.

Lymphangiomas of the tongue are relatively uncommon, and traditional treatment modalities carry a high failure rate. We present here a case report of effective treatment of lymphangioma circumscriptum of the oral tongue using radiofrequency coblation, while including a review of the current literature.
