ABSTRACT
@#A 61-year-old male diagnosed with laryngeal squamous cell carcinoma presented with hoarseness, progressive dysphagia leading to aspiration, and dyspnea one month after definitive radiation therapy. Examination revealed a diffusely swollen glottis, paralyzed vocal cords, and post-radiation fibrosis. Several glottic biopsies yielded results negative for malignancy and favored radiation-induced changes. When presented with the option of further diagnostic testing with a positron emission tomography (PET) scan or an outright laryngectomy, the patient decided on the latter. Final histopathologic diagnosis was negative for recurrence of malignancy. This case demonstrates treatment dilemmas for patients with laryngeal carcinoma with uncertain recurrence wherein radical surgical management may prove to be a viable option to achieve both diagnostic certainty and ultimate relief of symptoms.

Objective@#To review available resources and provide evidence-based recommendations that may optimize otorhinolaryngologic out-patient health care delivery in the “post”-COVID-19 era while ensuring the safety of our patients, healthcare workers and staff.@*Data Sources@#Relevant peer-reviewed journal articles; task force, organizational and institutional, government and non-government organization recommendations; published guidelines from medical, health-related, and scientific organizations.@*Methods@#A comprehensive review of the literature on the COVID-19 pandemic as it pertained to “post”-COVID 19 out-patient otorhinolaryngologic practice was obtained from peer-reviewed articles, guidelines, recommendations, and statements that were identified through a structured search of the data sources for relevant literature utilizing MEDLINE (through PubMed and PubMed Central PMC), Google (and Google Scholar), HERDIN Plus, the World Health Organization (WHO) Global Health Library, and grey literature including social media (blogs, Twitter, LinkedIn, Facebook). In-patient management (including ORL surgical procedures such as tracheostomy) were excluded. Retrieved material was critically appraised and organized according to five discussion themes: physical office set-up, patient processing, personal protection, procedures, and prevention and health-promotion.@*Conclusion@#These recommendations are consistent with the best available evidence to date, and are globally acceptable while being locally applicable. They address the concerns of otorhinolaryngologists and related specialists about resuming office practice during the “post”-COVID-19 period when strict quarantines are gradually lifted and a transition to the “new” normal is made despite the unavailability of a specific vaccine for SARS-CoV-2. While they target practice settings in the Philippines, they should be useful to ENT (ear, nose & throat) surgeons in other countries in ensuring a balance between service and safety as we continue to serve our patients during these challenging times.

@#<p><strong>OBJECTIVES:</strong> 1) To determine if there is an association between physical examination by cervical palpation, pre-operative contrast-enhanced multi-detector computed tomography (MDCT), and intraoperative lymph node assessment, with final histopathology in the evaluation of cervical lymph node metastasis in Filipino patients with squamous cell carcinoma of the head and neck. 2) To determine the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), accuracy, and likelihood ratios of cervical palpation, contrast enhanced MDCT, and intra-operative lymph node assessment compared with final histopathology in the evaluation of cervical lymph node metastasis in Filipino patients with squamous cell carcinoma of the head and neck.</p><p><strong>METHODS:</strong> Study Design. Retrospective; Cross-sectional. Setting. Tertiary Government Hospital Charity Section, Department of Otorhinolaryngology, Department of Radiology, Department of Pathology. Participants, Patients or Population. Retrospective chart review of all biopsy proven head and neck squamous cell carcinoma patients admitted at the charity ward of a Otorhinolaryngology Department from 2008-2010 who had documented admission physical examination, a pre-operative contrast enhanced multi-detector computed tomography (MDCT) scan of the neck done in the same institution within 20 days or less from date of surgery, and underwent neck dissection with appropriate cervical lymph node level specimen labeling with subsequent post-operative histopathologic evaluation of submitted specimens for neck node metastasis by the Pathology Department of the same institution. After set of exclusion criteria was applied, the analyzed sample included 82 lymph node level samples from 9 patients with head and neck Squamous Cell Carcinoma (SCCA).</p><p><strong>RESULTS:</strong> Pre-operative contrast enhanced MDCT, and intraoperative nodal assessment, were both significantly correlated with the final histopathologic evaluation of neck node metastasis as evaluated with Fisher's Exact test (p = 0.00). Cervical palpation however was not able to show a significant association (p=0.099).Cervical palpation had a sensitivity of 25.00% (8.33-52.59%), specificity of 90.91% (80.61-96.25%), NPV of 83.33 (72.30-90.73%), PPV of 40.00 (13.69-72.63%), accuracy of 78.05%, and a likelihood ratio of 3.33. Pre-operative contrast enhanced MDCT had a sensitivity of 43.75% (20.75-69.45%), specificity of 93.94% (84.44-98.04%), NPV of 87.32 (76.80-93.69%), , PPV of 63.64 (31.61-87.63%), accuracy of 84.15%, and a likelihood ratio of 12.06. Intraoperative surgical evaluation had a sensitivity of 68.75% (41.48-87.87%), specificity of 93.94% (84.44-98.04%), NPV of 92.54 (82.74-97.22%), PPV of 73.33 (44.83-91.09%), accuracy of 89.02%, and a likelihood ratio of 34.10. Further analysis with McNemar's Test comparing MDCT and Intraoperative assessment showed no significant difference (p = 0.387).</p><p><strong>DISCUSSION AND CONCLUSIONS:</strong> In the evaluation of cervical lymph node metastasis for head and neck squamous cell carcinoma in the local setting, the extent of neck dissection, clinical staging and prognosis, as well as adjuvant therapy can be guided by pre-operative contrast enhanced MDCT and intra-operative nodal assessment. Contrast-enhanced MDCT can aid treatment planning in preoperative or non-operative cases; but intraoperative evaluation can be used to guide final extent of surgery. Evaluation solely by physical examination by cervical palpation unfortunately in this study was not able to show a significant association with final histopathology.</p>
