Impacts of Recurrent Tonsillitis on the Outcome of Powered Intracapsular Tonsillectomy in Children

Background and Objectives@#To investigate the effects of recurrent tonsillitis on postoperative outcomes after powered intracapsular tonsillectomy and adenoidectomy (PITA) in children with obstructive sleep-disordered breathing (oSDB). @*Materials and Methods@#Children who underwent PITA in Kyung Hee University Hospital at Gangdong from 2016 to 2018 were classified into two oSDB groups according to comorbid chronic/recurrent acute tonsillitis (CHT). To evaluate the efficacy of the PITA technique, quality of life (QoL) was measured using the obstructive sleep apnea questionnaire (OSA-18) for 3 months after surgery. To evaluate the disadvantages of the PITA technique, we followed complications such as throat pain, otalgia, nausea, vomiting, and postoperative bleeding for 1 week after surgery. Finally, we compared the pre- and postoperative QoL and analyzed the incidence of postoperative complications in the oSDB with CHT (SDBwCHT) and oSDB without CHT (SDBsCHT) groups. @*Results@#Of the 802 enrolled patients, 135 were classified as SDBwCHT and 667 as SDBsCHT. Both groups exhibited marked improvements in QoL after PITA. The SDBwCHT group showed a change of OSA-18 score from 70.7±17.0 to 31.2±11.4. The SDBsCHT group showed a change of OSA-18 score from 70.0±17.1 to 31.0±9.9. The groups did not demonstrate statistical differences in complication rates and severity of symptoms during the first postoperative week. @*Conclusion@#Although comorbid CHT delayed improvement in postoperative symptoms, PITA is a useful technique to treat children with oSDB, regardless of CHT.

Laryngopharyngeal Reflux Disease: Diagnosis and Treatment in 2021

Laryngopharyngeal reflux disease (LPRD) is an inflammatory condition of the upper aerodigestive tract mucosa induced by reflux content from stomach. Some of vocal cord diseases are associated with laryngopharyngeal reflux. Because of the pathophysiological features, proton pump inhibitor shows therapeutic effect on some vocal cord diseases. As like that, the gastric reflux contents can make macroscopic or microscopic morphological changes in the upper aerodigestive tract mucosa. Although the pathophysiology of LPRD is relatively clear, clinical diagnosis is still difficult. The diagnosis of LPRD includes objective tests such as 24-hours multichannel intraluminal impedance-pH metry and subjective tests such as questionnaire method. However, the objective verification of reflux is difficult due to invasiveness of the method, and the questionnaire methods have limitations because many symptoms are not specific for LPRD. Moreover, most methods are not fully standardized until now. Despite these limitations, many researchers are struggling to standardize diagnosis and treatment of LPRD, and there are several new achievements recently. Therefore, the purpose of this article is to review the recent literature on the clinical presentation, diagnosis, and treatment of LPRD, and to systematize our knowledge.

Gene signature for prediction of radiosensitivity in human papillomavirus-negative head and neck squamous cell carcinoma

Purpose@#The probability of recurrence of cancer after adjuvant or definitive radiotherapy in patients with human papillomavirus-negative (HPV(–)) head and neck squamous cell carcinoma (HNSCC) varies for each patient. This study aimed to identify and validate radiation sensitivity signature (RSS) of patients with HPV(–) HNSCC to predict the recurrence of cancer after radiotherapy. @*Materials and Methods@#Clonogenic survival assays were performed to assess radiosensitivity in 14 HNSCC cell lines. We identified genes closely correlated with radiosensitivity and validated them in The Cancer Genome Atlas (TCGA) cohort. The validated RSS were analyzed by ingenuity pathway analysis (IPA) to identify canonical pathways, upstream regulators, diseases and functions, and gene networks related to radiosensitive genes in HPV(–) HNSCC. @*Results@#The survival fraction of 14 HNSCC cell lines after exposure to 2 Gy of radiation ranged from 48% to 72%. Six genes were positively correlated and 35 genes were negatively correlated with radioresistance, respectively. RSS was validated in the HPV(–) TCGA HNSCC cohort (n = 203), and recurrence-free survival (RFS) rate was found to be significantly lower in the radioresistant group than in the radiosensitive group (p = 0.035). Cell death and survival, cell-to-cell signaling, and cellular movement were significantly enriched in RSS, and RSSs were highly correlated with each other. @*Conclusion@#We derived a HPV(–) HNSCC-specific RSS and validated it in an independent cohort. The outcome of adjuvant or definitive radiotherapy in HPV(–) patients with HNSCC can be predicted by analyzing their RSS, which might help in establishing a personalized therapeutic plan.

Injury Mechanism to Induce Traumatic Balance Disorder / 대한평형의학회지

Many of the dizziness patients annually visit ENT (ear, nose, throat) clinics because the vestibular function is the major organ to keep body balance and belongs to the Otorhinolaryngology. Nevertheless, many otolaryngologists feel that it is not easy to access the dizziness patients. The reason is that dizziness is not a final diagnosis and it is necessary to start the diagnosis of dizziness and find out the cause. Also, the causes of dizziness belong to multiple medical departments. That is why we need to pay more attention. Among them, traumatic vertigo can be manifested in various ways depending on the injury site and mechanism, and it is often difficult to predict the medical prognosis. Therefore, this review article focuses on traumatic vertigo. In this paper, we discussed its epidemiology and mechanism to help clinicians to treat patients with traumatic vertigo.

Psychological Characteristics and Aesthetic Concerns of Male Patients Seeking Primary Rhinoplasty / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: The demand for rhinoplasty has been high for both men and women over the years; recently, however, it is rapidly increasing for men as their interest in aesthetics has heightened. This study investigated the psychological characteristics of male patients who underwent rhinoplasty through questionnaire-guided consultation. In addition, we investigated the difference between patients and surgeons regarding their aesthetic concerns for rhinoplasty. SUBJECTS AND METHOD: Of the male patients who underwent rhinoplasty from January 2006 to December 2012, 124 patients who had completed the questionnaires were included. The questionnaire for rhinoplasty asked about the basic personality traits of patients, patients' complaints about their nose, reasons for receiving the operation and expectation for postoperative change. RESULTS: Patients responded most to the item, “I have high expectations for the surgery” for the question regarding personality characteristics, followed by the response, “I am concerned about my health.” Regarding questions about reasons for rhinoplasty, complaints about their dorsum were high; among these patients, they were most concerned about the appearance of the ‘crooked nose’ when viewed from the front. On the other hand, the concern for the ‘poorly defined nasal tip’ was not high, whereas it was defined as one of the problems mentioned by the surgeons. CONCLUSION: These results show differences regarding aesthetic concerns between the patients and the surgeon, especially regarding the nasal tip. It would be helpful for both patient and surgen to plan the surgery after careful consultation based on the questionnaire, accurate understanding of the patients' complaints and expectations to obtain satisfactory results for both.

A Case of Subglottic Cancer with Saber Trachea

“Saber-sheath” trachea is a deformity of lower cervical or intrathoracic trachea. The configuration of the deformity is marked coronal narrowing associated with sagittal widening. This deformity is associated with chronic obstructive pulmonary disease. We report a case of patient with saber-sheath who underwent total laryngectomy. Although the patient had no tracheal collapse after the total laryngectomy, crusted discharge was increased. Diagnosis of the saber-sheath trachea, possible causes, and clinical implications are discussed.

A Case of Inflammatory Pseudotumor Cerebri and Nasal Septum / 대한이비인후과학회지

Inflammatory pseudotumors, which clinically mimic neoplasms, are space-occupying collections of inflammatory cells, histiocytes, and fibroblasts. They are most often found in the orbits and lungs, but rarely in the head and neck region, and hardly ever in the nasal septum. Here we report on a 71-year-old woman with pseudotumor cerebri and an inflammatory pseudotumor of the nasal septum. This case demonstrates that inflammatory pseudotumor can cooccur in the brain and nasal septum.
