RESUMO
BACKGROUND: The endoscopic modified medial maxillectomy (MMM) and prelacrimal approach (PLA) are two routinely performed endoscopic approaches to the maxillary sinus when access via a middle meatal antrostomy is insufficient. However, there is no data in the literature that has compared outcomes and complication profile between the two procedures to determine which approach is superior. OBJECTIVE: To compare the approach related morbidity of PLA and MMM. METHODS: A retrospective cohort study of all consecutive adult patients undergoing either MMM or PLA from 2009 to 2023 were identified. The primary outcome was development of epistaxis, paraesthesia, lacrimal injury, iatrogenic sinus dysfunction within a minimum of 3 months post-operative follow up. RESULTS: 39 patients (44 sides) underwent PLA and 96 (96 sides) underwent MMM. There were no statistically significant differences between the rates of paraesthesia (9.1 % vs 14.6 %, p = 0.367) or prolonged paraesthesia (2.3 % vs 5.2 %, p = 0.426), iatrogenic maxillary sinus dysfunction (2.3 % vs 5.2 %, p = 0.426) or adhesions requiring removal (4.5 % vs 4.2 %, p = 0.918). No cases of epiphora or nasal cavity stenosis occurred in either arm in our study. CONCLUSIONS: According to our data, the endoscopic modified medial maxillectomy and prelacrimal approach are both equally safe approaches with their own benefits to access.

PURPOSE: To assess the accuracy of deep learning models for the diagnosis of maxillary fungal ball rhinosinusitis (MFB) and to compare the accuracy, sensitivity, specificity, precision, and F1-score with a rhinologist. METHODS: Data from 1539 adult chronic rhinosinusitis (CRS) patients who underwent paranasal sinus computed tomography (CT) were collected. The overall dataset consisted of 254 MFB cases and 1285 non-MFB cases. The CT images were constructed and labeled to form the deep learning models. Seventy percent of the images were used for training the deep-learning models, and 30% were used for testing. Whole image analysis and instance segmentation analysis were performed using three different architectures: MobileNetv3, ResNet50, and ResNet101 for whole image analysis, and YOLOv5X-SEG, YOLOv8X-SEG, and YOLOv9-C-SEG for instance segmentation analysis. The ROC curve was assessed. Accuracy, sensitivity (recall), specificity, precision, and F1-score were compared between the models and a rhinologist. Kappa agreement was evaluated. RESULTS: Whole image analysis showed lower precision, recall, and F1-score compared to instance segmentation. The models exhibited an area under the ROC curve of 0.86 for whole image analysis and 0.88 for instance segmentation. In the testing dataset for whole images, the MobileNet V3 model showed 81.00% accuracy, 47.40% sensitivity, 87.90% specificity, 66.80% precision, and a 67.20% F1 score. Instance segmentation yielded the best evaluation with YOLOv8X-SEG showing 94.10% accuracy, 85.90% sensitivity, 95.80% specificity, 88.90% precision, and an 89.80% F1-score. The rhinologist achieved 93.5% accuracy, 84.6% sensitivity, 95.3% specificity, 78.6% precision, and an 81.5% F1-score. CONCLUSION: Utilizing paranasal sinus CT imaging with enhanced localization and constructive instance segmentation in deep learning models can be the practical promising deep learning system in assisting physicians for diagnosing maxillary fungal ball.
RESUMO
This study aimed to investigate the impact of three-dimensional (3D) technology on preoperative evaluation for rhinoplasty.A systematic search was conducted on Embase, MEDLINE, and Web of Science. Studies that utilized 3D technology in preoperative assessment for rhinoplasty were included. The primary outcome was surgeon and patient satisfaction. The secondary outcomes included nasal function, cost-efficiency, reoperation rate, precision, and surgical time.Twelve studies (595 patients) were included. Surgeons reported higher satisfaction with 3D approaches based on precision and postoperative results. Patients expressed satisfaction with the 3D approaches due to a better understanding of the procedure and the ability to discuss with the surgeons planning the procedure and participating in postoperative design. The 3D approaches demonstrated higher surgeon satisfaction (mean difference -0.13, 95% confidence interval [CI] -0.20 to -0.06, p = 0.0002), particularly in revision cases, and provided higher precision compared with the two-dimensional (2D) approaches. However, 3D technology was more expensive and not cost-efficient. There were no significant differences in reoperation rate (odds ratio 0.16, 95% CI 0.02-1.36, p = 0.09) and surgical time. Postoperative nasal function showed inconsistent results.3D technology offered higher surgeon satisfaction and increased precision compared with 2D imaging. However, 3D imaging was expensive and not cost-efficient. Reoperation rate and surgical time were comparable, while postoperative nasal function outcomes showed inconsistent results.
RESUMO
PURPOSE OF REVIEW: To analyze and compare the effects of epistaxis treatments for Hereditary Hemorrhagic Telangiectasia (HHT) patients. RECENT FINDINGS: Of total of 21 randomized controlled trials (RCT), the data from 15 RCTs (697 patients, 7 treatments: timolol, propranolol, bevacizumab, doxycycline, tacrolimus, estriol/estradiol, and tranexamic acid) were pooled for the meta-analyses while the other 6 studies (treatments: electrosurgical plasma coagulation, KTP laser, postoperative packing, tamoxifen, sclerosing agent, and estriol) were reviewed qualitatively. When compared to placebo, propranolol offered the most improved epistaxis severity score, mean difference (MD), -1.68, 95% confidence interval (95%CI) [-2.80, -0.56] followed by timolol, MD -0.40, 95%CI [-0.79, -0.02]. Tranexamic acid significantly reduced the epistaxis frequency, MD -1.93, 95%CI [-3.58, -0.28]. Other treatments had indifferent effects to placebo. Qualitative analysis highlighted the benefits of tamoxifen and estriol. The adverse events of tranexamic acid, tacrolimus, propranolol, and estradiol were significantly reported. Propranolol, timolol, tranexamic acid, tamoxifen, and estriol were effective treatments which offered benefits to HHT patients in epistaxis management. Adverse events of tranexamic acid, tacrolimus, propranolol, and estradiol should be concerned.

PURPOSE OF REVIEW: To analyze and compare the effects of herbal medicines (HMs) for treating different forms of rhinosinusitis. RECENT FINDINGS: Forty-seven randomized controlled trials evaluating 18 HMs in six different rhinosinusitis populations were included in the network meta-analysis. Certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. For the common cold, Pelargonium sidoides offered the most beneficial effect on symptom improvement (moderate certainty of evidence). For acute post-viral rhinosinusitis, Cineole and Pelargonium sidoides were the most effective treatments for controlling symptoms (moderate certainty), while Spicae aetheroleum was most effective for health-related quality of life (HRQoL) improvement (moderate certainty). For chronic rhinosinusitis without nasal polyps (CRSsNP), Origanum vulgare was the most beneficial treatment for improving symptoms and HRQoL (low certainty). Evidence of HMs for acute bacterial rhinosinusitis, chronic rhinosinusitis with nasal polyps, and unclassified chronic rhinosinusitis was restricted to a limited number of studies. Adverse events should be of concern in some HMs, such as Spicae aetheroleum or Mytorl. Several HMs improved patient-important outcomes, above minimal clinically important differences, in treating common cold, acute post-viral rhinosinusitis, and CRSsNP. Further studies with adequate sample sizes and long-term follow-ups are warranted to support the current evidence. TRIAL REGISTRATION NUMBER AND DATE OF REGISTRATION: PROSPERO ID: CRD42022328265 May 10, 2022.

PURPOSE: Microscopic Draf 2a frontal sinusotomy relied on direct access. However, the modern-day endoscopic approach is hindered by the anterior-posterior dimensions of the frontal recess. The nasofrontal beak, angled endoscopes, and variable frontal recess anatomy make the surgery challenging. Carolyn's window frontal sinusotomy removes the limitation of anterior-posterior dimensions and is an endoscopic version of the microscopic Draf 2a. This study aims to compare the perioperative outcomes and morbidity from endoscopic direct access Draf 2a compared to angled access Draf 2a. METHODS: Consecutive adult patients (> 18 years) seen at a tertiary referral clinic who underwent Draf 2a frontal sinus surgery using either endoscopic direct access (Carolyn's window) or endoscopic angled instrumentation were included. Patients who underwent Carolyn's window were compared to those with angled Draf 2a frontal sinusotomy. RESULTS: One hundred patients (age 51.96 ± 15.85 years, 48.0% female, follow-up 60.75 ± 17.34 months) were included. 44% of patients used Carolyn's window approach. 100% [95% CI 98.2-100%] of patients achieved successful frontal sinus patency. Both groups were comparable for early morbidities (bleeding, pain, crusting, and adhesions) and late morbidities (retained frontal recess partitions). There were no other morbidities in the early and late postoperative periods. CONCLUSION: The endoscopic direct access Draf 2a, or Carolyn's window, removes the anteroposterior diameter limitation. The frontal sinus patency and early and late surgical morbidities of direct access Draf 2a were comparable with the angled Draf 2a frontal sinusotomy. Surgical modifications, often with drills and bone removal, can be successfully made to enhance access in endoscopic sinus surgery without concern for additional morbidity.

BACKGROUND: Preclinical studies demonstrated anti-inflammatory effects of Zingiber montanum (J.König) Link ex Dietr.(Phlai). However, its clinical effect on allergic rhinitis (AR) is not evident. OBJECTIVE: We sought to assess the efficacy and safety of Phlai for treating AR. METHODS: A phase 3, randomized, double-blind, placebo-controlled study was conducted. Patients with AR were randomized into three groups and received Phlai 100 mg or Phlai 200 mg or placebo once a day for four weeks. The primary outcome was a change in the reflective total five symptom score (rT5SS). The secondary outcomes were the change in the instantaneous total five symptom score (iT5SS), the reflective individual symptom scores (rhinorrhea, nasal congestion, sneezing, itchy nose, itchy eyes), Rhinoconjunctivitis Quality of Life-36 Questionnaire (RCQ-36) score, peak nasal inspiratory flow (PNIF), and adverse events. RESULTS: Two hundred and sixty-two patients were enrolled. Compared with placebo, Phlai 100 mg improved rT5SS [adjusted mean difference (aMD) -0.62; 95%CI -1.22, -0.03; p = 0.039], rhinorrhea (aMD -0.19; 95%CI -0.37, 0.002; p = 0.048), itchy nose (aMD -0.24; 95%CI -0.43, -0.05; p = 0.011), and itchy eyes (aMD -0.19; 95%CI -0.36, -0.02; p = 0.033) at week 4. Nasal obstruction, sneezing, iT5SS, overall RCQ-36 score, PNIF did not reach statistical significance. Phlai 200 mg did not bring additional benefits compared to 100 mg. Adverse events were similar among groups. CONCLUSIONS: Phlai was safe. At four weeks, there were small improvements in rT5SS, together with the individual symptoms of rhinorrhea, itchy nose, and itchy eyes.
RESUMO
BACKGROUND: Patients with diabetes mellitus (DM) are susceptible to invasive fungal rhinosinusitis (IFRS). The mortality rate of IFRS varies greatly among the patients with DM. OBJECTIVE: To identify the prognostic factors for the overall survival of patients with DM and IFRS. METHODS: A retrospective study was conducted in four tertiary hospitals in Thailand, Malaysia and Myanmar. Patients diagnosed with IFRS and DM from 2008 to 2019 were identified. The outcome was the overall survival. Variables analyzed for risk factors were age, HbA1C level, ketoacidosis, white blood cell count, hyperglycemia, duration of DM, current use of diabetic medications, serum creatinine level, and the extensions of IFRS to the orbit, the cavernous sinus and intracranial cavity. RESULTS: Sixty-five diabetic patients with IFRS (age 57.9 ± 13.4 years, male 60%) were identified. The mortality rate was 21.5%. The extensions of IFRS to the cavernous sinus (hazard ratio 5.1, 95% CI [1.4-18.2], p = 0.01) and intracranial cavity (hazard ratio 3.4, 95% CI [1.1-11.3, p = 0.05) predicted mortality. Current use of diabetic medications decreased the mortality risk (hazard ratio 0.2, 95% CI [0.1-0.9], p = 0.03). The 6-month overall survival of the patients with and without the cavernous sinus extension were 51.4% and 83.6%, (p = 0.001), with and without intracranial extension 53.3% and 88.9%, (p = 0.001), and with and without current diabetic medications 82.3% and 57.5%, respectively (p = 0.045). CONCLUSIONS: The extensions of IFRS to the cavernous sinus and intracranial cavity increased the risk of death in patients with DM. Survival was primarily related to current use of diabetic medications.

OBJECTIVES: We assessed associations of potential factors with orbital complications in acute rhinosinusitis (ARS) patients. DESIGN: An unmatched case-control study. SETTING: A tertiary referral hospital in Thailand. PARTICIPANTS: Consecutive outpatients of any age with severe ARS (visual analog scale ≥ 7) with and without orbital complications. MAIN OUTCOME MEASURES: Patients were enrolled from January 2013 to December 2018. Forty-three ARS patients (55.8% female, median age 45.6, (range 2.0-93.0) years) were included, with 19 patients in the complicated group and 24 in the uncomplicated group. Patient characteristics (gender, age, diabetes, immune status), symptoms and signs, site of infection and type of pathogenic bacteria were recorded and assessed their associations with orbital complications by univariable and multivariable logistic regression analyses. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. RESULTS: The most common orbital complication was subperiosteal abscess (42.1%), followed by orbital cellulitis (15.8%) and cavernous sinus thrombosis (10.5%). Multivariable logistic regression analysis demonstrated a positive association with orbital complications (pseudo R2 0.4) for ethmoid sinusitis (OR 31.1, 95% CI [2.3-430.6]) and a short duration of symptoms (OR 0.9, 95% CI [0.8-0.9]). CONCLUSIONS: Orbital complications were associated with ethmoid sinusitis with a short duration of ARS symptoms.

PURPOSE: Endoscopic sphenopalatine artery ligation (ESPAL) is known as an effective treatment for posterior epistaxis. Anatomical variations of the intranasal branching may result in long operative time and possible inadequate cauterization. A modification of ESPAL by cauterization at the sphenopalatine foramen (SPF), has been performed by our group. Our study assessed the clinical benefit of endoscopic sphenopalatine foramen cauterization (ESFC) and compared it to ESPAL. METHOD: A retrospective study was conducted. Patients who received ESFC for posterior epistaxis from 2016 to 2018 at a tertiary hospital were recruited. Middle meatal antrostomy was done. After ethmoidal crest was identified and nipped, pterygopalatine fossa was entered through the SPF. Sphenopalatine artery (SPA) and its branches within the SPF were cauterized without identification of any SPA distal branches in the nasal cavity. Patients receiving conventional ESPAL by the same surgeon were recruited and compared as control. Patients were followed-up for 3 months. Success rate, operative time, and complication were assessed. RESULTS: Thirty-four patients were identified. Recurrent epistaxis was absent in 90.0% and 100% of patients receiving ESPAL (9/10 patients) and ESFC (24/24 patients) respectively, p = 0.294. Median operative time was 115 and 60 min, respectively, p < 0.001. Ipsilateral hard palatal or anterior palatal numbness were found in one and three patients, respectively. All resolved spontaneously within 2 weeks. CONCLUSION: ESFC is effective in treating posterior epistaxis. It requires significantly less amount of time while the success rate was comparable to conventional ESPAL.

During the initial pandemic wave of COVID-19, apart from common presenting symptoms (cough, fever, and fatigue), many countries have reported a sudden increase in the number of smell and taste dysfunction patients. Smell dysfunction has been reported in other viral infections (parainfluenza, rhinovirus, SARS, and others), but the incidence is much lower than SARS-CoV-2 infection. The pathophysiology of post-infectious olfactory loss was hypothesized that viruses may produce an inflammatory reaction of the nasal mucosa or damage the olfactory neuroepithelium directly. However, loss of smell could be presented in COVID-19 patients without other rhinologic symptoms or significant nasal inflammation. This review aims to provide a brief overview of recent evidence for epidemiology, pathological mechanisms for the smell, and taste dysfunction in SARS-CoV-2 infected patients. Furthermore, prognosis and treatments are reviewed with scanty evidence. We also discuss the possibility of using "smell and taste loss" as a screening tool for COVID-19 and treatment options in the post-SARS-CoV-2 infectious olfactory loss.

Olfactory and gustatory dysfunctions (OGD) are pathognomonic symptoms in patients with Coronavirus Disease 2019 (COVID-19). This study reviews the associations of OGD with COVID-19 which will be useful for early diagnosis and self-isolation. Systematic searches of PubMed, Ovid Medline, Scopus, and EMBASE electronic databases were performed. Studies reporting OGD in COVID-19 patients were included. Data were pooled for meta-analysis. The outcomes were odds ratios (OR) of OGD in COVID-19 patients. Proportions of smell and/or taste dysfunctions in the COVID-19 patients were assessed. Fourteen studies (21,515 participants, age 49.12 years, 26% male) were included. The OR of olfactory and/or gustatory dysfunctions in COVID-19 patients were 11.26 (95% confidence interval (CI) 5.41 to 23.4) when compared with acute respiratory infection (ARI) without detectable virus and 6.46 (95% CI 2.79 to 14.97) in patients with other respiratory viruses. The OR of olfactory dysfunction in COVID-19 patients were 11.67 (95% CI 6.43 to 21.17) when compared with the ARI patients without detectable virus and 4.17 (95% CI 1.34 to 12.98) with other respiratory viruses. The OR of gustatory dysfunction in COVID-19 patients were 12.70 (95% CI 7.9 to 20.44) when compared with the ARI patients without detectable virus and 4.94 (95%CI 1.59 to 15.31) with other respiratory viruses. Fifty percent (95% CI 36.7 to 63.3%) of COVID-19 patients had olfactory and/or gustatory dysfunctions. In summary, there are associations between OGD and COVID-19 patients. Patients presenting with ARI should be assessed for olfactory and gustatory functions.

PURPOSE OF REVIEW: Preliminary studies have suggested differences in endotypes of chronic rhinosinusitis (CRS) across ancestry/ethnic groups. Eosinophilic CRS (ECRS) is the predominant subtype for Western/European ancestry CRS patients and non-eosinophilic CRS (nECRS) for Asian patients. This review aims to re-analyze CRS endotypes across ancestry populations using one consistent criteria to existing data. RECENT FINDINGS: Although tissue eosinophilia is the most commonly used criterion for ECRS, various cut-off points are suggested. Surrogate markers have been extensively studied. Sixty-six cohorts with study criteria were included with a total of 8557 patients. Raw data from 11 studies 544 patients were re-analyzed using number of tissue eosinophils. At lower cut-off values of ≥ 5 and ≥ 10 cells/HPF, most patients of Asian and Western/European ancestry were classified as ECRS without difference. In contrast, at cut-off points of ≥ 70 and ≥ 120 cells/HPF, the majority of both groups became reclassified as nECRS. After applying one consistent criteria to existing data, differences across ancestry and geographic populations in endotypes of CRS were no longer evident.

The lateral recess of a well-pneumatized sphenoid sinus is challenging to access surgically. Traditional methods require the use of multiple angled endoscopes and curved instruments which may limit visualization. We describe a prelacrimal-transpterygoid/maxillary approach which offers direct access to this region with a 0° endoscope. Laryngoscope, 2024.
RESUMO
OBJECTIVES: The aim was to assess the developmental attributes of sphenoid sinuses affected by fungal balls and describe a surgical approach which reestablishes gravity-dependent drainage to compensate for any mucociliary dysfunction. METHODS: A within-patient case-control analysis was performed on sphenoid sinus dimensions from patients with sphenoid sinus fungal ball (SSFB). Radiological dimensions were assessed to determine the dominant or larger sinus by volume and width. Pneumatization in the sagittal and lateral extent was assessed. The influence of sinus size and pneumatization variants within a patient was analyzed. Patency and the presence of mucostasis from radical reshaping of the sinus cavity were documented at least 3 months after surgery. Complications (bleeding, cerebrospinal fluid leak, and cranial nerve palsy) were recorded. RESULTS: Twenty-three patients (59 ± 19 years, 86% female, 46 sphenoid sinuses) were assessed. Fungal ball was more common in the smaller (non-dominant) sinus, by width (78% vs. 22%, p < 0.01) and by proportion of total sphenoid volume (0.39 ± 0.16 vs. 0.61 ± 0.16, p < 0.01). Pneumatization variants did not influence the development of SSFB within a patient. All patients had patency and the absence of mucostasis or persistent inflammation at last follow-up. No complications were reported. CONCLUSION: The smaller or nondominant sphenoid sinus is more affected by SSFB. Surgical reshaping of the sphenoid to prevent mucostasis is favorable in managing the smaller affected sinus cavity. LEVEL OF EVIDENCE: 4 Laryngoscope, 2024.
RESUMO
Objective: To compare the effectiveness between cyanoacrylate tissue adhesives (CTAs) and sutures for skin closure on the face and neck. Data Sources: Embase, Medline, Scopus, Central, Web of Science. Review Methods: Randomized controlled trials comparing CTAs versus sutures for skin closure on the face and neck were included. Primary outcomes were cosmetic outcomes. Secondary outcomes were scar depth, scar width, pain, closure time, cost, and adverse events. Subgroup analyses were performed by wound locations, type of CTAs, type of sutures, age groups, and type of wounds. Physicians and patients evaluated the cosmetic outcomes. Results: Eighteen studies (1020 patients) were included. CTAs offered better cosmetic outcomes by Wound Registry Scale at ≤1 month (physician: mean difference [MD]: -1.50, 95% confidence interval, CI: -2.42 to -0.58). The cosmetic outcomes assessed by Visual Analog Scale were comparable at >1 to ≤3 months (physicians: standard mean difference [SMD], -0.01, 95% CI, -0.25 to 0.23, patients: SMD, -0.02, 95% CI, -0.84 to 0.79). The cosmetic outcomes by the Patient and Observer Scar Assessment Scale favored sutures at >3 to 12 months (physician: MD 4.26, 95% CI, 2.02-6.50). Subgroup analyses revealed no differences. CTAs offered less scar depth, scar width, pain, closure time, and total cost of closure. Adverse events were similar. Conclusion: Based on the wound healing process, the cosmetic outcomes exhibited a favorable inclination toward CTAs at <1 month while demonstrating comparable results between CTAs and sutures at >1 to ≤3 months. Subsequently, sutures exhibited superior cosmetic outcomes compared to CTAs at >3 to 12 months.
RESUMO
OBJECTIVES: The benefit of corticosteroids following facial nerve neurorrhaphy in the setting of complete transection is questionable. This systematic review and meta-analysis aimed to evaluate corticosteroid efficacy on facial nerve regeneration and functional recovery after complete disruption and neurorrhaphy. METHODS: Randomized controlled trials on both human and animal models from Ovid MEDLINE and Ovid EMBASE studying corticosteroid efficacy in complete facial nerve disruption followed by neurorrhaphy were included. Data were extracted and pooled for meta-analysis. The outcomes were evaluated from electrophysiology, histology, and functional recovery. However, no randomized controlled trial in human was performed. Possibly, performing human trials with histopathology may not be feasible in clinical setting. RESULTS: Six animal studies (248 participants) met inclusion criteria. Electrophysiologic outcomes revealed no differences in latency (Standardized Mean Difference (SMD)â¯=â¯-1.97, 95% CI -7.38 to 3.44, pâ¯=â¯0.47) and amplitude (SMDâ¯=â¯0.37, 95% CI -0.44 to 1.18, pâ¯=â¯0.37) between systemic corticosteroids and controls. When analysis compared topical corticosteroid and control, the results provided no differences in latency (Mean Difference (MD)â¯=â¯0.10, 95% CI -0.04 to 0.24, pâ¯=â¯0.16) and amplitude (SMDâ¯=â¯0.01, 95% CI -0.08 to 0.10, pâ¯=â¯0.81). In histologic outcomes, the results showed no differences in axon diameter (MDâ¯=â¯0.13, 95% CI -0.15 to 0.41, pâ¯=â¯0.37) between systemic corticosteroid and control; however, the result in myelin thickness (MDâ¯=â¯0.06, 95% CI 0.04 to 0.08, pâ¯<â¯0.05) favored control group. When comparing systemic corticosteroid with control in eye blinking, the results favored control (MDâ¯=â¯1.33, 95% CI 0.60 to 2.06, pâ¯=⯠0.0004). CONCLUSIONS: This evidence did not show potential benefits of systemic or topical corticosteroid deliveries after facial nerve neurorrhaphy in complete transection when evaluating electrophysiologic, histologic, and functional recovery outcomes in animal models.

OBJECTIVE: To evaluate the role of a negative pressure room with a high-efficiency particulate air (HEPA) filtration system on reducing aerosol exposure in common otolaryngology procedures. STUDY DESIGN: Prospective quantification of aerosol generation. SETTINGS: Tertiary care. METHODS: The particle concentrations were measured at various times during tracheostomy tube changes with tracheostomy suctioning, nasal endoscopy with suctioning, and fiberoptic laryngoscopy (FOL), which included 5 times per procedure in a negative pressure isolation room with a HEPA filter and additional 5 times in a nonpressure-controlled room without a HEPA filter. The particle concentrations were measured from the baseline, during the procedure, and continued until 30 minutes after the procedure ended. The particle concentrations were compared to the baseline concentrations. RESULTS: The particle concentration significantly increased from the baseline during tracheostomy tube changes (mean difference [MD] 0.80 × 106 p/m3 , p = .01), tracheostomy suctioning (MD 0.78 × 106 p/m3 , p = .004), at 2 minutes (MD 1.29 × 106 p/m3 , p = .01), and 3 minutes (MD 1.3 × 106 p/m3 , p = .004) after suctioning. There were no significant differences in the mean particle concentrations among various time points during nasal endoscopy with suctioning and FOL neither in isolation nor nonpressure-controlled rooms. CONCLUSION: A negative pressure isolation room with a HEPA filter was revealed to be safe for medical personnel inside and outside the room. Tracheostomy tube change with tracheostomy suctioning required an isolation room because this procedure generated aerosol, while nasal endoscopy with suctioning and FOL did not. Aerosol generated in an isolation room was diminished to the baseline after 4 minutes.

BACKGROUND: Middle meatal antrostomy (MMA) is the traditional intervention for chronic maxillary sinusitis but often fails to correct a nonfunctioning maxillary sinus that has lost its capability for mucociliary clearance. Endoscopic-modified medial maxillectomy (EMMM) can reshape the maxillary sinus and avoid a "sumping" effect, preventing secondary bacterial colonization, encouraging dependent drainage, and promoting effective nasal irrigation. OBJECTIVES: We describe a modification of the EMMM surgical technique in patients with recalcitrant maxillary sinusitis and perioperative outcomes. METHODS: Consecutive adult patients with nonfunctioning maxillary sinuses managed with EMMM were assessed. Primary outcomes were the resolution of the presenting symptom and the absence of mucostasis. Secondary outcomes were early (<90 days) and late (>90 days) morbidity. RESULTS: Fifty-seven patients (51.7 ± 17.5 years, 56.1% female) were assessed. Fifty-two patients had complete resolution of their presenting symptom (91.2% [95% CI: 80.7-97.1]) and 52 patients had an absence of mucostasis (91.2% [95% CI: 80.7-97.1]). Those with persistent crusting were also those with symptoms. Early morbidities included temporary dysesthesia (3.2%), bleeding (1.1%), and pain (3.2%), with no late morbidities. CONCLUSION: EMMM is a robust approach for salvaging a nonfunctioning maxillary sinus. The procedure enhances nasal irrigation, supplants mucociliary clearance, and discourages dependent mucus retention.
