RESUMEN
Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

<p><b>OBJECTIVE</b>To investigate the surgical technique which could preserve the swallowing and laryngeal function effectively in the malignant head and neck tumors involving the tongue root.</p><p><b>METHODS</b>From January 2003 to December 2008, 31 cases of malignant head and neck tumors involving the tongue base had been treated in this hospital were retrospectively analyzed. There were 27 males and 4 females in which 9 cases of primary malignant tumor were from the base of tongue; 3 cases were from the tonsil, 11 cases were from supraglottic laryngeal carcinoma and 8 cases were from hypopharyngeal carcinoma. Preserved the lingual artery of the reserved side and the normal tissue of the root of tongue according to the clinical anatomy of lingual artery during the operation. If preoperative CT had indicated that bilateral lingual arteries were involved, total glossectomy should have been done. The epiglottis, vocal cords and the ventricular band of larynx was preserved as much as possible for the mechanisms of laryngeal function.</p><p><b>RESULTS</b>In this group, residual tongue necrosis did not occurred. One case with total glossectomy didn't remove the trachea cannula. Five had total laryngectomy. The other 25 cases decannulated from 14th days to 90th days postoperatively. The time of oral feeding was started from 10th days to 31st days postoperatively. Two cases with hypopharyngeal carcinoma developed fistula, which were cured by dressing change. Two with root of tongue cancer and 1 with tonsil cancer had postoperative infection and healed in 2 weeks. The median follow-up time was 36 months, and the Kaplan-Meier 3-years and 5-years survival rates were 79.5% and 69.6% respectively.</p><p><b>CONCLUSIONS</b>In the surgical treatments of the malignant head and neck tumors involving the base of tongue, the excisions and reconstructions of the primary tumor and the involved tongue base according to the clinical anatomy of lingual artery and the protection mechanisms of laryngeal function during the operation was one of the most effective technique to preserve the swallowing and laryngeal function.</p>

<p><b>OBJECTIVE</b>To study the indication and clinical application of lateral neck incision for the removal of cervical esophageal foreign bodies.</p><p><b>METHODS</b>From January 1999 to January 2009, 2189 cases esophageal foreign bodies were treated. The clinical data of 137 cases (6.25%) with lateral neck incision were retrospectively analyzed. In these 137 cases, 114 cases were over 16-years-old (adult group), while 23 cases were under 16-years-old (children group). In adult group, 67 cases (58.8%) had esophageal perforation (esophageal perforation with neck abscess 29 cases, esophageal perforation without neck abscess 38 cases); 47 cases did not have esophageal perforation (impacted foreign body without neck abscess 40 cases, foreign body with esophageal abscess 7 cases). In children group, 19 cases (82.6%) had esophageal perforation including 15 cases with neck abscess; 4 cases without esophageal perforation, 3 cases had esophageal abscess and one case without abscess but of huge foreign body.</p><p><b>RESULTS</b>All 137 patients with foreign body were cured through lateral neck incision. Nineteen cases (13.9%) had hoarseness and recovered in 3 months. Five adult patients had post-operative cicatricial stricture of the esophagus, but it was mild and completely recovered by the treatment of dilatation in 3 to 11 months. Nine adult patients with esophageal perforation were cured by secondary suture, the remaining esophageal perforation cases were healed by first intention. One case with common carotid artery impairement by the foreign body was successfully treated by carotid artery ligation without hemiplegia, aphasia and other sequelae. Two cases had cardiopulmonary arrest, 2 cases had febrile convulsions and 1 case had acute respiratory failure, 5 cases had septic shock, all these patients were effectively controlled and cured. Seven of the 9 cases with tracheotomy had the tracheal tube removed during hospitalization; 1 of the two obese patients had the extubation 3 months after the discharge and the other one still had the tube. All esophageal perforation cases in children group had primary healing by perforation apposition suture. Four of the 5 children had successful tracheotomy decannulation, one child had extubation by 2 months through continuously reduced tracheal tube model.</p><p><b>CONCLUSION</b>Penetrating esophageal foreign body and neck abscess were indication of the lateral neck incision, and positive prevention and cure the complications of lateral neck incision could achieve good curative effect.</p>

<p><b>OBJECTIVE</b>To discuss the effective emergency treatment to patients with different malignant tumors of head and neck after treatment.</p><p><b>METHODS</b>Eighteen hemorrhage patients which have been successfully rescued with different malignant head and neck neoplasias after operation and (or) radiotherapy were analyzed retrospectively. Emergency treatment was used in 1 patient with nasopharyngeal cancer (NPC) suffering from massive epistaxis and suffocation after radiotherapy. The digital subtraction angiography (DSA) was used in 6 patients suffering from rupture of internal maxillary artery after irradiation for NPC. Two cases suffering from ulcer bleeding from deep par of pars nasalis pharyngis underwent repair of galea aponeurotic after elotomy. Hemostasis by finger pressing and per-cutsem ligation of carotid were used in 9 patients who suffered from rupture of carotid artery, then underwent normal treatment in operating room.</p><p><b>RESULTS</b>Ligation of carotid artery was used in one patient with NPC after radiotherapy suffering from bleeding from arteria carotis interna of skull base. DSA was used in 6 patients with hemorrhage of nasopharynx who was confirmed rupture of internal maxillary artery by CT and DSA. Two cases suffering from ulcer bleeding from deep par of pars nasalis pharyngis underwent repair of galea aponeurotic; pectoralis major myocutaneous flap and infra-trapezius were used in 7 patients with laryngocarcinoma, carcinoma of infra-pharynx, thyroid carcinoma and lymphadenoma of cervical part, 6 cases of them were successful while 1 patient's pectoralis major myocutaneous flap partly necrosis. One patient with thyroid carcinoma who can not be repaired after many operations and radiotherapies. One patient with lymphoma of cervical part also can not be repaired because bad body condition. All cases have no hemiplegic paralysis after first aid. One cases with NPC suffering from massive epistaxis that after ligation of carotid artery suffered from partly cerebral infarction and died of pulmonary infection 6 months postoperatively; 2 cases of nasopharyngeal carcinoma died of recurrence 11 months postoperatively; other cases died of recurrence (7 cases), metastasis and/or multi organic failure of the whole body (8 cases) from 12 to 36 months.</p><p><b>CONCLUSION</b>Different treatments were used in different cases, The DSA and per cutsem Ligation of artery after hemostasis by finger pressing were the modus operandi for NPC patients with intractable epistaxis after radiotherapy and patient suffered from rupture of carotid artery respectively.</p>

<p><b>OBJECTIVE</b>To evaluate therapeutic effect in a consecutive series of patients with node-positive of N1 and N2 head and neck squamous cell carcinoma (HNSCC) who underwent selective neck dissection as part of their treatment in a single institution.</p><p><b>METHODS</b>Retrospectively analyzed 36 patients with node positive head and neck squamous cell carcinoma, which had undergone 40 selective neck dissection (SND) and 16 radical neck dissections (RND) and the therapeutic effects of the SND in HNSCC patients with node positive. Kaplan-Meier method was used to estimate the survival analysis among the different levels, and log-rank method for comparison of the different distribution of the several influential factors of the survival; the fisher's exact test was used to test the difference of the neck recurrence between the groups that with or without lymph node extracapsular spread. Cox proportional hazard model was applied to screen the potentially significant prognostic factors.</p><p><b>RESULTS</b>The 3 and 5 years survival rate of this group were 76.8% and 54.3% retrospectively. The 3 and 5 years' survival rate were both 100% in the N1 + N2a group, while 59.4% and 32.0% in the N2b + N2c group correspondingly. With log-rank test between the two groups above, significant statistical difference was revealed (P = 0.003) in the 5 years' survival rates. To the groups that with or without extracapsular spread (ECS), the recurrence rate were 36.4% and 3.4% respectively and significant statistical difference existed (P = 0.015). In the groups that with or without ECS, the 3 years' survival rate were 45.5% and 81.8% , and 5 years' survival rate were 39.7% and 65.5% respectively, also the significant statistical difference (P = 0.0148 and P = 0.0423 respectively) had presented.</p><p><b>CONCLUSIONS</b>SND is appropriate for treatment of N1 neck of the patient with HNSCC; However, SND should be taken very cautious to the N2 neck and node-positive neck with extracapsular spread, MRND or RND might be a better choice to prevent the recurrence in the neck.</p>
