RESUMEN
PURPOSE: The efficacies of hyperbaric oxygen therapy (HBO), systemic steroid, prostaglandin E1, or the combination of any two modalities have been reported in patients with idiopathic sudden sensorineural hearing loss (ISSNHL). However, little is known about the combined efficacy of HBO, systemic steroid, and prostaglandin E1 for this disorder. We aimed to investigate the efficacy of HBO combined with systemic steroids and prostaglandin E1 as triple therapy in patients with ISSNHL. MATERIALS AND METHODS: We retrospectively evaluated the records of 67 patients with ISSNHL who were treated with systemic steroid and prostaglandin E1, with (n = 38) or without (n = 29) HBO. The inclusion criteria included a diagnosis of ISSNHL within 14 days of symptom onset, age ≥15 years, treatment according to the protocol, and clinical follow-up of at least 1 month. The patients' hearing levels were evaluated 1 month after hearing loss onset. The primary outcome was hearing improvement on pure tone audiometry. We also evaluated the demographic profiles of patients. RESULTS: Patients treated with triple therapy showed significantly greater hearing improvement (p < 0.01) than those treated without HBO, despite some differences between the two treatment groups. Multivariate logistic regression analysis revealed a significant positive correlation between pure tone audiometry improvement and hyperbaric oxygen therapy, after adjustment for confounding factors (odds ratio = 7.42; 95% and confidence interval = 2.37-23.3; p = 0.001). CONCLUSION: HBO with systemic steroid and prostaglandin E1 administration conferred significant therapeutic benefits for ISSNHL. Therefore, routine use of triple therapy is recommended for patients with ISSNHL.

Solitary fibrous tumors (SFTs) are rare mesenchymal tumors that occur in various soft tissues and organs throughout the body. Superficial SFTs in the head and neck region are uncommon and reports of such cases are limited. An elderly Japanese woman in her 80s presented to our clinic with a smooth mass in the right parotideomasseteric region. Ultrasonography and magnetic resonance imaging revealed a well-defined subcutaneous mass measuring 20 mm. For a definitive diagnosis and treatment, surgical resection was performed under local anesthesia. Intraoperatively, a brown-colored tumor was identified beneath the skin, without surrounding tissue adhesion, and was completely excised. Immunohistochemistry, revealing the expression of STAT6, confirmed the diagnosis of SFT. Based on the SFT risk classification, this case was classified into the low-risk group, and no recurrence occurred during the 4 year postoperative period. According to the 2020 World Health Organization Classification of Soft Tissue Tumors, SFTs belong to the intermediate category with recurrence potential. In previous studies, cases of positive margins and recurrence have been reported in superficial SFTs, and SFTs may show benign features on clinical presentation but require precise surgical manipulation. Therefore, it is crucial for otolaryngologists to gain a comprehensive understanding of this tumor for appropriate treatment.
RESUMEN
A case of nasopharyngeal tuberculosis with cervical lymph node tuberculosis is reported. The patient was a 20-year-old female immigrant from Vietnam and cook apprentice. Her chief complaint was left neck swelling with pain for three months. She was diagnosed with left neck lymphadenitis at a previous hospital, which suspected malignant lymphoma and referred her to our hospital. At the time of the first visit, she had left lymph swelling with tenderness and granuloma-like masses in the nasopharynx. PET-CT showed accumulations in both the swollen left neck lymph and nasopharynx. The diagnosis of this case would appear to be nasopharyngeal cancer with left and neck lymph node metastasis or nasopharyngeal tuberculosis with cervical lymph node tuberculosis in addition to malignant lymphoma. Based on some examinations (biopsy, bacteria culture, and imaging), it was diagnosed as nasopharyngeal tuberculosis with cervical lymph node tuberculosis. Therefore, she was treated with anti-tuberculosis agent in respiratory medicine.
RESUMEN
We experienced a case of huge chronic thyroiditis with malignant lymphoma that caused dyspnea with tracheal stenosis, dysphagia with esophagus stenosis and recurrent nerve paralysis. In this case, thyroidectomy was performed and, after the surgery, there was no sign of breathing or swallowing difficulties, and it was confirmed by the postoperative computed tomography that the tracheal stenosis had improved. We considered two possible explanations for the preoperative right recurrent nerve paralysis. In the first, the right recurrent nerve could have suffered from mechanical stimulation such as compression and traction to the recurrent nerve due to enlargement of the malignant lymphoma together with chronic thyroiditis. The second possible explanation was that malignant cells had invaded neurons. We could not distinguish between the two possibilities, since this right recurrent nerve was spared and could not be examined histopathologically.
RESUMEN
Introduction Eosinophilic chronic rhinosinusitis (ECRS) is characterized by an eosinophilic inflammation driven by Th2-type cytokines. Glucocorticosteroids are the most common first-line treatment for ECRS with nasal polyps. Objective We have evaluated the long-term treatment with double-dose intranasal corticosteroids in refractory ECRS nasal polyps resistant to the conventional dose and assessed the risk of adverse systemic effects Methods Sixteen subjects were enrolled in this study. All subjects had ECRS after endoscopic sinus surgery that resulted in recurrent mild and moderate nasal polyps and were undergoing a postoperative follow-up application of mometasone furoate at a dose of 2 sprays (100 µg) in each nostril once a day (200 µg). All the patients were prescribed mometasone furoate, administered at a dose of 2 sprays (100 µg) in each nostril twice a day (400 µg) for 6 months. Results The average scores of the symptoms during the regular dose of intranasal steroid treatment were 5.2 ± 2.2, but 6 months after the high-dose application, they had significantly decreased to 2.5 ± 1.4 ( p < 0.05). The polyp size showed an average score of 1.38 during the regular dose which was significantly reduced to 0.43 ( p < 0.01) by the double dose. Glycated hemoglobin (HbA1c) showed normal ranges in all the patients tested. The cortisol plasma concentration was also normal. Conclusion Doubling the dose of the nasal topical spray mometasone furoate might be recommended for the treatment of recurrent nasal polyps in the postoperative follow-up of intractable ECRS.
RESUMEN
We experienced a case of an elongated styloid process that was 8 cm in length. The patient was a 68-year-old Japanese man with frequent episodes of left-sided throat pain for 10 years. The elongated styloid process could be diagnosed by 3D-computed tomography (left and right length: 7.8 cm and 8.0 cm, respectively) and successfully treated with surgery, since the anatomic relationships could be fully visualized. Surgical methods for shortening an elongated styloid process involve an intraoral or external approach. The external approach to the styloid process involves a trans-cervical approach to the parapharyngeal space, which enables wider visualization in the operative field than an intraoral approach. In the present case, the styloid process reached the parapharyngal space. Therefore, we selected the external approach and shortened only the left-sided styloid process (the same side as the throat pain). The chief complaint disappeared immediately after the operation.
RESUMEN
We experienced two rare cases with laryngeal cystic lesions (laryngocele and laryngeal cyst). In the first case, the laryngocele case was removed by laryngomicrosurgery using an oral approach under general anesthesia. In the second case, the magnetic resonance imaging demonstrated a dumbbell-type cyst with mucus widely extending from the laryngeal lumen to the neck through the thyroid cartilage. The patient had undergone chemotherapy for renal carcinoma with multiple lung and bone metastases. Therefore, we performed only fine needle aspiration rather than aggressive surgery for extirpation of the cyst using an external approach. This fine needle aspiration could improve the quality of life by decreasing both the left laryngeal swelling and the resulting pain, which were the chief complaints.
RESUMEN
We experienced a rare case of laryngeal cancer associated with dermatomyositis. The patient was a 63-year-old male and Japanese. He was admitted to our department of Otorhinolaryngology with dysphagia for a day as a chief complaint. He became aware of hoarseness with bloody sputum and then face edema with redness a half year before. At first physical examination, he had bilateral eyelid edema with erythema, finger edema with keratinizing erythema and limb extensor erythema. Serous creatine phosphokinase was 850 IU/mL (normal range: 40-200 IU/mL). Later, he was referred to the rheumatology department and was diagnosed as having dermatomyositis. Fiberscopic examination revealed laryngeal cancer with left laryngeal palsy. We gave priority to the laryngeal treatment. As a result, the symptoms of dermatomyositis were improved.
RESUMEN
We experienced a very rare case of maxillary bone metastasis from lung cancer. The patient was a 77-year-old Japanese man with 1-month history of right alar swelling with hard pain as his chief complaint. Computed tomography scan showed a 1 cm length round lesion in the right nasal vestibule close to the pyriform fossa edge of the right maxillary bone. He had severe pulmonary dysfunction due to recurrent end stage lung cancer and diabetes. The expected remainder of his life would be half a year. Therefore, his very poor condition precluded general anesthesia. To relieve the nasal pain, shorten the stay in the hospital and improve the quality of life (QOL), we performed minimally invasive surgery under local anesthesia. Our minimally invasive surgery could improve QOL by relieving the hard nasal pain until the recurrence of cancer and enable the patient to live at home.
RESUMEN
Brn4, which encodes a POU transcription factor, is the gene responsible for DFN3, an X chromosome-linked, non-syndromic type of hearing loss. Brn4-deficient mice have a low endocochlear potential (EP), hearing loss, and ultrastructural alterations in spiral ligament fibrocytes, however the molecular pathology through which Brn4 deficiency causes low EP is still unclear. Mutations in the Gjb2 and Gjb6 genes encoding the gap junction proteins connexin26 (Cx26) and connexin30 (Cx30) genes, respectively, which encode gap junction proteins and are expressed in cochlear fibrocytes and non-sensory epithelial cells (i.e., cochlear supporting cells) to maintain the proper EP, are responsible for hereditary sensorineural deafness. It has been hypothesized that the gap junction in the cochlea provides an intercellular passage by which K+ is transported to maintain the EP at the high level necessary for sensory hair cell excitation. Here we analyzed the formation of gap junction plaques in cochlear supporting cells of Brn4-deficient mice at different stages by confocal microscopy and three-dimensional graphic reconstructions. Gap junctions from control mice, which are composed mainly of Cx26 and Cx30, formed linear plaques along the cell-cell junction sites with adjacent cells. These plaques formed pentagonal or hexagonal outlines of the normal inner sulcus cells and border cells. Gap junction plaques in Brn4-deficient mice did not, however, show the normal linear structure but instead formed small spots around the cell-cell junction sites. Gap junction lengths were significantly shorter, and the level of Cx26 and Cx30 was significantly reduced in Brn4-deficient mice compared with littermate controls. Thus the Brn4 mutation affected the assembly and localization of gap junction proteins at the cell borders of cochlear supporting cells, suggesting that Brn4 substantially contributes to cochlear gap junction properties to maintain the proper EP in cochleae, similar to connexin-related deafness.
