Objective: To determine the relationship between olfactory function threshold and quality of life (QOL) among adult Filipinos with perceived olfactory dysfunction (OD). Methods: Design: Cross - Sectional Study Setting: Tertiary Government Training Hospital Participants: 98 adults who had self-perceived olfactory dysfunction described as “poor” or “no sense” of smell Results: We analyzed data from 98 participants, with a mean age of 35.91 + 12.58 years old, composed of 46 men (47%) and 52 women (53%), with 82 normosmic, six hyposmic and ten anosmic as categorized by their BTT scores. Twenty-seven percent (27%) identified themselves as having poor QOL based on Fil 17 QODNS. Differences were exhibited between sexes’ BTT scores - [t(96) = -2.32; p = .022; females, M: 9.25; SD: 2.33 vs. males, M: 7.76; SD : 3.91], civil status Fil17QODNS scores [t(96)= 3.05, p < .003; married M: 11.72, SD: 13.74 vs. single, M: 4.71; SD: 8.66), and the presence of ENT symptoms BTT [t(96) = -7.15; p < .0001; symptomatic, M: 5.62; SD: 4.54, vs. asymptomatic, M: 9.78; SD: 1.14] and Fil 17 QODNS scores [t(96)= 3.94; P < .00001; symptomatic, M: 14.86; SD: 13.97] vs. asymptomatic, M: 5.217; SD: 9.60]. Significant risk factors were the presence of ENT symptoms [OR= 0.15; 95% CI: 0.02-0.97; P = .046] for poor smell threshold, and comorbidities [OR= 3.36; 95% CI: 1.04-10.85; P = .043] for poor QOL. A negative correlation was observed between Fil-QOD-NS scores and BTT scores [r = -0.477, p < .001; rs = -0.292, p = .004], signifying that the presence of olfactory dysfunction has an inverse relationship with the quality of life. Conclusion: Individuals with olfactory dysfunction in this study population had poor quality of life as determined by the translated Filipino 17-item QOD-NS which has an inverse relationship with their smell threshold as represented by the BTT results. Among the factors studied, significant differences were found between sexes, civil status and presence of ENT symptoms in the BTT and Fil 17 QODNS scores. However, only presence of comorbidities and ENT symptoms are significant risk factors for quality of life and smell threshold, respectively, in this population.

Objective: To report an alternative combined gingivobuccal and endoscopic endonasal approach to treating ossifying fibroma of the left maxilla. Methods: Design: Case Report Setting: Tertiary Private University Hospital Patient: A 19-year-old girl with a progressively enlarging left cheek mass for 3 years. Results: Our patient underwent left medial maxillectomy via a combined gingivobuccal and endoscopic endonasal approach with complete resection and significant improvement of symptoms, with good functional outcome. Conclusion: Large ossifying fibromas of the maxilla can be completely and successfully excised via a combined gingivobuccal and endoscopic endonasal approach.

Keywords: ophthalmic artery; vasospasm; iatrogenic; endoscopic sinus surgery; blindness Endoscopic sinus surgery (ESS) is a generally benign, minimally invasive procedure used for management of paranasal sinus diseases, although complications may occur due to proximity of vital structures such as the brain, orbit and great vessels.1 The overall ESS major complication rate is 0.5-1%, of which orbital injury accounts for 0.09% due to direct trauma.2 We report a case of unilateral delayed sudden visual loss without orbital trauma observed intraoperatively or on post[1]operative imaging studies, following a seemingly routine endoscopic sinus surgery for chronic rhinosinusitis. CASE REPORT An 18-year-old lad with no significant medical history underwent ESS for bilateral chronic rhinosinusitis with nasal polyposis. (Figure 1 A-D) The surgery and recovery from anesthesia were uneventful. On the 12th hour post-operatively, the patient noted blurring of vision on the left. Ophthalmologic examination revealed hyperemic conjunctiva (Figure 2A) with visual acuity of counting fingers at 1 foot while fundoscopy showed retinal hemorrhages. Extraocular eye movements (EOM) and intraocular pressure (IOP) were normal (12mmHg). With an assessment of pre-retinal hemorrhages, 500 mg Tranexamic acid was intravenously infused, and a paranasal sinus (PNS) computed tomography (CT) scan and orbital magnetic resonance imaging (MRI) were requested. A few hours later, he complained of left eye pain with increasing intensity and further deterioration of vision. Repeat visual acuity testing showed light perception. There was now a constricted pupil, non-reactive pupillary light reflex, periorbital swelling and progression of conjunctival chemosis. (Figure 2B) The IOP of the left eye had increased to 30mmHg then progressed to 40mmHg with development of total visual loss and a lateral gaze limitation. With an impression of choroidal hemorrhage and retrobulbar hemorrhage, a lateral canthotomy relieved the eye pain. The contrast PNS CT scan with orbital cuts showed that the lamina papyracea was intact with no definite hemorrhagic collections in the intraconal or extraconal spaces of both orbits. (Figure 3A, B) A small hyper density along the lateral inferior margin of the left globe at the intraconal region with slight thickening of the anterior periorbital region represented the lateral canthotomy. The PNS MRI / magnetic resonance angiography (MRA) with orbital cuts showed retinal detachment and periorbital edema in the left eye. (Figure 4) A B-Scan ocular ultrasonogram showed retinal detachment and vitreous opacities. The diagnosis was ocular ischemic syndrome secondary to ophthalmic artery vasospasm, and the patient was given sublingual nitroglycerine and intravenous dexamethasone 8mg every 12 hours for 24 hours, with improvement of periorbital swelling. He was discharged after 12 days with no resolution of the unilateral visual loss.

ABSTRACT Background: Olfactory dysfunction (OD) in COVID-19 presents as a sudden onset smell loss commonly seen in mild symptomatic cases with or without rhinitis but can occur as an isolated symptom. The reported prevalence of OD among COVID-19 patients ranged from 5% to 98%. Although numerous studies have been conducted about their association, these were mainly based on self-reported cases and subjective questionnaires. Objective: This study investigates whether there is a significant difference in the prevalence of olfactory dysfunction between self-reported and objective testing using validated objective olfactory tests among RT-PCR confirmed COVID-19 patients. Methods: PubMed (MEDLINE), Cochrane, Web of Science, and Google Scholar were searched for studies investigating the prevalence of OD by using objective olfactory tests among patients who self-reported OD (November 1, 2019 to July 31, 2020). All studies were assessed for quality and bias using the Cochrane bias tool. Patient demographics, type of objective olfactory test, and results of self-reported OD and objective testing were reported. Results: Nine studies encompassing 673 patients met the inclusion criteria. Validated objective olfactory tests used in the included studies were CCCRC, SST and SIT. Overall prevalence of OD among patients who self-reported was higher after objective testing (71% versus 81%). This was also seen in when we performed subgroup analysis based on the objective tests that were used. However, meta-analysis using random effects model showed no significant difference in the overall prevalence of OD (p value=.479, 95% CI 56.6 to 84.0 versus 71.2 to 89.8) as well as in the subgroups. Conclusion: To the best of our knowledge, this is the first meta-analysis that statistically reviewed articles that evaluated the difference between self-reported and objective tests done on the same patients. Results showing that self-reporting OD approximates the results of the objective tests among COVID-19 positive patients may imply that self-reporting can be sufficient in contact tracing and triggering swabbing and self quarantine during the time of COVID-19 and objective tests can be used as an adjunct in the diagnosis particularly in research. However, this study was limited by small sample size and articles done in European countries hence, interpretation and application of the results of this study must be approached with care. Further studies documenting the difference between self-reporting and objective test in large scale setting involving different countries may be helpful in establishing a definitive consensus.

ABSTRACT Objective: To compare the radiographic features of the nasal septal swell body (NSB) with the laterality of nasal septal deviation and investigate whether there is a correlation between the severity of the septal deviation and difference in NSB size. Methods: Design: Retrospective Observational Study Setting: Tertiary Private University Hospital Participants: 30 paranasal sinus computerized tomography scans from January to October 2017 Results: A septal deviation was present in 60% of the subjects. In 78% of cases with septal deviation, the NSB was noted to be significantly larger on the side opposite the nasal septal deviation (p < .05). Conclusion: The correlation between the severity of the septal deviation and difference in NSB size had a value of (r = 0.37) therefore, no positive correlation was established. Subjects with almost symmetric NSB measurements tend to have no septal deviation. On the other hand, the NSB is more prominent contralateral to a septal deviation.
