Purpose Severe acute respiratory syndrome caused by COVID-19 has spread globally for the last few months. Healthcare workers (HCW) are overexposed and infection rates are higher than in the rest of the population. Strict clinical assessment is paramount to detect suspicious cases. In this context, olfactory or taste dysfunction (OTD) appears as an early and frequent symptom. Evaluating its presence in early stages plays an important role nowadays. Methods We performed a descriptive observational single-center study among 256 HCW at Hospital Universitario de Fuenlabrada affected by COVID-19 and confirmed using RT-PCR. A telephonic interview was performed, after obtaining oral informed consent. Results OTD was present in up to 70% of the cases as an early symptom, including mild-to-severe cases. The extent of these sensory deficits lasted an average of 11 days. In 26% of the patients, these sensory alterations persisted for over a month. Conclusion OTD is reported as an early symptom among HCW with SARS-CoV-2 infection. Its strong association with test positivity is useful in the management of the infection and should be enough to indicate preventive isolation. We consider that OTD needs to be included in clinical screening questionnaires in HCW.

We report the results of one-stage multilevel upper airway surgery for patients who could not tolerate continuous positive airway pressure (CPAP). Patients treated with multilevel surgery at a University Hospital in 2015–2019 were identified from a prospectively maintained database. The inclusion criteria were aged 18–70 years, body mass index (BMI) < 35 kg/m2, apnea–hypopnea index (AHI) > 20, and lingual tonsil hypertrophy grade 3 or 4. Drug-induced sleep endoscopy was performed before surgery in all patients. Multilevel surgery was performed in one stage and included expansion sphincter pharyngoplasty (ESP), coblation tongue base reduction (CTBR), and partial epiglottectomy (PE) as required. The outcome measures were postoperative AHI, time percentage oxygen saturation < 90%, and Epworth Sleepiness Scale (ESS) score. A total of 24 patients were included: median age 49.1 years, average BMI 27.26 kg/m2, and 90% men. Ten patients received ESP plus CTBR plus PE, eight received ESP plus CTBR, and six received ESP plus PE. The mean preoperative AHI was 33.01 at baseline and improved to 17.7 ± 13 after surgery (p < 0.05). The ESS score decreased from 11 ± 5.11 to 7.9 ± 4.94 (p < 0.05). The surgical success rate according to Sher’s criteria was 82.3%. The median follow-up was 23.3 months (range 12–36). These findings suggest that multilevel surgery is a safe and successful treatment of OSAHS.

Objective: The aim of this study is to evaluate the effects of nasal surgery in the upper airway (UA) collapse using drug induced sleep endoscopy (DISE) in a group of patients with obstructive sleep apnea hypopnea syndrome (OSAHS). Methods: Prospective cohort of patients treated with nasal surgery between 2015 and 2016. All patients were diagnosed with mild to severe OSAHS. The inclusion criteria were age between 18 and 70 years, apnea–hypopnea index (AHI) higher than 15, and septal deviation. All patients had a DISE performed before surgery and 3 months after. The DISE findings were evaluated through the NOHL scale. Results: Thirty-four patients were included. Surgical success with subjective and objective improvement in nasal obstructions was achieved in all cases. The pattern of UA obstruction did change significantly following nasal surgery (P < 0.05). Before nasal surgery, 74% of the patients demonstrated multilevel obstruction. After nasal surgery, only 50% patients showed multilevel collapse (P < 0.05). Among patients with single-level collapse, the oropharynx was the most common location of obstruction. It became more frequent after nasal surgery was done (41% vs 21%, P < 0.05). Significant improvement was shown in hypopharyngeal collapse. Postoperative AHI decreased from a mean of 26.7 to 19 events/h, but this change was not significant. Conclusion: Nasal surgery may improve hypopharyngeal collapses observed during DISE in patients with OSAHS. Thus, an improvement in nasal obstruction may also modify the surgical plan based on UA functional findings in OSAHS patients.
