Drainage of a Pterygopalatine Fossa Abscess With Chronic Sinusitis via an Endoscopic Nasal Approach.

The pterygopalatine fossa is a clinically inaccessible space deep in the face, and reports of pterygopalatine fossa abscesses are rare. The authors present the case of a 63-year-old woman presenting with a severe headache owing to an abscess involving the pterygopalatine fossa. On a computed tomography scan, inflammation of the right pterygopalatine fossa associated with right maxillary sinusitis and periapical inflammation and a cystic lesion around the tooth were observed. After administering appropriate antibiotics, the headache improved considerably, and endoscopic nasal surgery resulted in adequate abscess drainage. To the authors' knowledge, this case study is one of the few reporting the successful treatment of an abscess in the pterygopalatine fossa through an endoscopic transnasal approach.

Association between poly-sensitisation and sensitisation to staphylococcal enterotoxin A and B affecting allergic severity in children.

PURPOSE: Accumulating evidence suggests that Staphylococcus aureus plays a significant role as a disease modifier in upper and lower airway diseases. We aimed to assess the association between staphylococcal enterotoxins (SEs) with allergic diseases and the degree of allergen sensitisation in children, which remains unclear. METHODS: We retrospectively reviewed the medical records of 455 patients aged 3-18 years between March 2018 and March 2022. Clinical history and demographic data were obtained. The baseline study included paranasal sinus X-ray scan, multiple allergen simultaneous test, and ImmunoCAP® for measuring serum total and specific immunoglobulin E (IgE) levels to allergens and staphylococcal enterotoxin A and B (SEA and SEB). RESULTS: The mean age was 9.77 ± 4.3 years. 133 patients (29.2%) were sensitised to one inhalant allergen, and 188 patients (41.3%) showed polysensitisation. Patients sensitised to SEs showed higher total and specific IgE levels and total eosinophil counts compared to non-SE-sensitised patients. Sensitisation to SEs is closely associated with polysensitisation to inhalant allergens and allergic multimorbidity. When the SE-IgE value was 0.35 or higher, the odds ratio for allergen polysensitisation was significantly higher than when the SE-IgE value was lower than 0.35. CONCLUSIONS: Association between polysensitisation and sensitisation to SEs in children shows the higher the specific IgE levels for SEs, the higher the likelihood of polysensitisation. Considering the relationship between polysensitisation, high IgE levels, and the severity of allergic morbidity, sensitisation to SEs is thought to be related to allergy severity.

Occurrence of a postoperative maxillary mucocele 20 years after orbital wall reconstruction.

Mucoceles of the paranasal sinus are epithelial-lined cystic structures filled with mucus and have multiple etiologies, including recurrent inflammation, trauma, or intrinsic disease. Particularly, a postoperative maxillary mucocele (POMM) is a delayed complication of radical surgery of the maxillary sinus, and most cases occur after Caldwell-Luc operations. Patients mainly complain of facial swelling, toothache, and tenderness. POMM has rarely been reported from other causes; however, there have been no reports on the occurrence of POMM following orbital wall reconstruction. Herein, we report a case of a patient with a POMM that developed 20 years after the aforementioned surgery. The patient complained of facial pain with visual disturbance, and underwent marsupialization using a combination of sublabial and endoscopic approaches, and the symptoms improved without recurrence.

Nasopharyngeal Tuberculosis with Concomitant Middle Ear Tuberculosis: A Case Report and Literature Review.

Tuberculosis (TB), an infectious disease caused by Mycobacterium tuberculosis (MTB), can affect the lungs (pulmonary TB) as well as other sites (extrapulmonary TB). Nasopharyngeal tuberculosis (NPTB) is a rare type of extrapulmonary TB. Since NPTB has nonspecific clinical presentation with low index of suspicion, it is difficult for clinicians to make an early diagnosis and proper treatment. We recently encountered a 42-year-old woman with NPTB concomitant with middle ear TB, which strongly mimicked nasopharyngeal carcinoma. Since the diagnosis of NPTB was difficult to confirm based on endoscopic findings and imaging studies, this patient underwent nasopharyngeal biopsy, and finally, polymerase chain reaction (PCR) confirmed NPTB. This report describes our NPTB case as well as summarizes all cases of NPTB reported in South Korea. We highlight that active tissue biopsy with antibacterial smear and additional PCR or specific TB blood test should be considered for cases with high suspicion of NPTB.

Usefulness of stress-related hormones as predictors and prognostic factors for idiopathic sudden sensorineural hearing loss.

BACKGROUND: The pathogenesis of Idiopathic sudden sensorineural hearing loss (ISSNHL) is ambiguous. Stress is commonly defined as a cause of the disease. Serum levels of stress-related hormone (cortisol, growth hormone, aldosterone, ADH, ACTH) may be elevated in patients with ISSNHL patients. OBJECTIVES: We aimed to determine whether psychological factors and stress hormones in patients are associated with the severity of hearing loss and therapeutic outcomes. We hypothesized that the stress hormone level in the disease sequence is a strong prognostic factor of ISSNHL. Additionally, we investigated whether the subjective degree of psychological stress is likely to contribute to the therapeutic prognosis of ISSNHL, as determined using questionnaires. METHODS: We conducted a prospective study of patients aged between 19 and 65 years admitted for the treatment of ISSNHL at our hospital. All patients underwent pure tone audiometry (PTA) on day 0, day 5 and 2 weeks after discharge. As an objective indicator of stress, we measured the level of HPA axis-related hormones. So, we measured serum cortisol, adrenocorticotropic hormone (ACTH), aldosterone and dehydroepiandrosterone sulfate (DHEAS) levels in the venous blood sample of patients on day 1 and day 5 after admission. In addition, for subjective stress measurements, depression and anxiety levels were assessed using self-reported questionnaires, Beck Depression Inventory (BDI), and Perceived Stress Scale (PSS) in the revised to Korean versions. RESULTS: Eighteen patients diagnosed with ISSNHL at the Department of Otorhino-laryngology were enrolled. Serum DHEAS level measured on day 1 showed a statistically significant correlation with the hearing threshold in the hearing test performed at the time of diagnosis (p = .037, correlation coefficients(r) = 0.541). Serum ACTH level was measured on day 1, and patients were classified into normal and elevated groups based on a threshold of 1.5 pg/mL; the normal group had better hearing thresholds in the first and second hearing test than the elevated group (p = .040, 0.015, respectively). In the stress-related questionnaires, the BDI score showed a statistically significant correlation with the last hearing test (p = .015, correlation coefficients(r) = 0.613). CONCLUSION: We demonstrated the possible role of stress-related hormones in the pathogenesis of ISSNHL and suggest that depressive stress response can be a strong predictor of treatment response in patients with ISSNHL. However, the impact of response to stress on the inner ear and endolymph homeostasis remains unknown. Since this is a cross-sectional study, we can only comment on the relationship between stress and ISSNHL, not a causal relationship. Further investigation is necessary to identify the mechanism of interaction between stress and hearing ability in the inner ear.
