The temporal course of COVID-19 anosmia and relation to other clinical symptoms.

OBJECTIVE: This study aimed to define the clinical course of anosmia in relation to other clinical symptoms. METHODS: 135 patients with COVID-19 were reached by phone and subsequently included in the study. Olfactory functions were evaluated using a questionnaire for assessment of self-reported olfactory function. Patients were divided into four subgroups according to the presence of olfactory symptoms and temporal relationship with the other symptoms: group1 had only olfactory complaints (isolated, sudden-onset loss of smell); group2 had sudden-onset loss of smell, followed by COVID-19 related complaints; group3 initially had COVID-19 related complaints, then gradually developed olfactory complaints; and group4 had no olfactory complaints. RESULTS: In total, 59.3% of the patients interviewed had olfactory complaints during the disease course. The olfactory dysfunction severity during COVID-19 infection was significantly higher in group1 compared to groups 2 and 3. In groups1-3, the odor scores after recovery from COVID-19 disease were significantly lower compared to the status prior to disease onset. The residual olfactory dysfunction was similar between groups1 and 2, but was more evident than group3. Mean duration for loss of smell was 7.8 ± 3.1 (2-15) days. Duration of loss of smell was longer in groups1 and 2 than in group3. Odor scores completely returned back to the pre-disease values in 41 (51.2%) patients with olfactory dysfunction. Rate of complete olfactory dysfunction recovery was higher in group3 compared to groups1 and 2. CONCLUSION: In isolated anosmia cases, anosmia is more severe, and complete recovery rates are lower compared to the patients who have other clinical symptoms. LEVEL OF EVIDENCE: Level 4.

Minimally invasive injection laryngoplasty in the management of unilateral vocal cord paralysis after video-assisted mediastinal lymph adenectomy.

INTRODUCTION: Video-assisted mediastinal lymphadenectomy (VAMLA) is a valuable tool for invasive staging of the mediastinum. Unilateral vocal cord paralysis (UVCP) may occur in patients following VAMLA and may result in secretion retention within the lungs, atelectasis and associated infectious situations such as pneumonia. Minimally invasive injection laryngoplasty (ILP) is the treatment of choice in UVCP. AIM: To evaluate the efficacy and success of acute minimally invasive injection laryngoplasty for patients with UVCP following VAMLA. MATERIAL AND METHODS: Patients with the symptom of dysphonia following VAMLA were reviewed. All of the patients had UVCP according to the video laryngoscopy examination and had symptoms of aspiration and ineffective coughing. The Voice Handicap Index (VHI) questionnaire and maximum phonation time (MPT) were measured. Minimally invasive ILP was performed under general anesthesia with 1 cm of hyaluronic acid. RESULTS: There were 525 consecutive non-small cell lung cancer (NSCLC) patients who underwent VAMLA. Five (0.95%) of the patients had UVCP and were suffering from aspiration during oral intake and ineffective coughing reflex. Maximum phonation time (MFT) was measured before and after ILP, and the results were 7.1 ±1.6 and 11.1 ±2.3 s, respectively (p < 001). The Voice Handicap Index-10 (VHI-10) score was 30.4 ±4.7 and 13.4 ±3.5 (p < 0.01), respectively. Patients underwent surgical lung resection. There was no morbidity or mortality. CONCLUSIONS: Unilateral vocal cord paralysis may occur as a complication of VAMLA. ILP may be an active tool for treating UVCP before anatomical lung resection to avoid potential morbidities. Successful management of this complication with multidisciplinary team work may encourage the use of VAMLA more frequently.

Cellular Angiofibroma of the Nasopharynx.

Angiofibroma is a common tumor of the nasopharynx region but cellular type is extremely rare in head and neck. A 13-year-old boy presented with frequent epistaxis and nasal obstruction persisting for 6 months. According to the clinical symptoms and imaging studies juvenile angiofibroma was suspected. Following angiographic embolization total excision of the lesion by midfacial degloving approach was performed. Histological examination revealed that the tumor consisted of staghorn blood vessels and irregular fibrous stroma. Stellate fibroblasts with small pyknotic to large vesicular nuclei were seen in a highly cellular stroma. These findings identified cellular angiofibroma mimicking juvenile angiofibroma. This article is about a very rare patient of cellular angiofibroma of nasopharynx.

Connecticut (CCCRC) Olfactory Test: Normative Values in 426 Healthy Volunteers.

Application of Connecticut Chemosensory Clinical Research Center (CCCRC) olfactory test to healthy Turkish volunteers, obtain normative data set and analyse the role of age, sex and smoking on olfactory scores. The present study was conducted at Bezmialem Vakif University, Department of Otorhinolaryngology. Total of 426 healthy volunteers were subjected to CCCRC olfactory test which consists of n-butanol smell threshold test and smell identification test. Olfactory function score was assessed (0: worst score; 7: best score) and mean scores were calculated. Mean age was (36.7 ± 11.1; range, 17-68). 46.2 % of the subjects were male and 53.8 % were female; 37.1 % were smokers and 62.9 % were non-smokers. Mean n-butanol threshold score was 6.36 out of 7, mean identification score was 6.34 and mean total score was 6.35. According to CCCRC score: there were no anosmic individuals, 0.5 % were severely hyposmic, 2.6 % were moderately hyposmic,15.3 % were mildly hyposmic and 81.6 % were normosmic. CCCRC olfactory test is cost-effective, simple and practical. It can be easily applied in clinical settings. The CCCRC olfactory test is appropriate for assessment of olfactory function: Turkish population is familiar in terms of the odors used in CCCRC test. The power of this study is that it provides a normative data set against which many factors can be compared.

Pre-auricular and ascending helical free composite flap in reconstructing an alar defect resulting from a human bite: a case report.

Full-thickness defects of the nose result in severe aesthetic and functional problems. Nasal alar defects are frequently caused by trauma, surgical resection or congenital deformities, yet an alar defect due to a human bite is quite rarely seen. For a successful alar reconstruction, selected tissue must be similar to nasal structures in texture, color and thickness. The structural similarities between the nasal alae and auricular helices have allowed the use of free helical composite flaps for the repair of nasal defects. In this article, we report a 36-year-old male patient who had a right alar defect caused by a human bite. The defect was successfully reconstructed with a reverse flow superficial temporal vessel based pre-auricular and ascending helical free composite flap. Since the color and the texture of the flap was compatible with the nose integuments, this flap enjoyed of an optimal integration in the central facial area.
