Septal Nasopharyngeal "Kite Flap" for Long-Term Patency of Petrous Apex Cholesterol Granuloma.

Medial petrous apex cholesterol granuloma is a benign lesion which treatment is generally based on a trans-nasal marsupialization. When the artificial ostium is created, it is usually kept open with local flaps, like the septal nasopharyngeal "kite flap", a reliable local vascularized flap. Laryngoscope, 134:2111-2114, 2024.

[Salivary gland infections or sialadenitis]. / Pathologies infectieuses des glandes salivaires ou sialadénites.

SALIVARY GLAND INFECTIONS OR SIALADENITIS. Salivary infections, or sialadenitis, affect all types of patients but are most common in elderly or dehydrated patients. Clinical signs include pain, skin erythema, gland oedema, fever and sometimes pus visible at the ostium. In the absence of doubt, no investigation is necessary apart from bacteriological sampling. Ultrasound scan should be performed if there is a doubt about the diagnosis or signs of complications. The treatment of bacterial sialadenitis is based on a probabilistic antibiotic therapy then adapted, for a duration of 10 days. The most frequent germ is Staphylococcus aureus. Rehydration is essential, especially in the elderly. The treatment of viral sialadenitis, which resolves in 8 to 15 days, is symptomatic. If the evolution is most often positive, the risk of serious complications requires a rapid diagnosis and appropriate treatment.

PATHOLOGIES INFECTIEUSES DES GLANDES SALIVAIRES OU SIALADÉNITES. Les infections salivaires, ou sialadénites, touchent tout type de patients mais concernent surtout des patients âgés ou déshydratés. Les signes cliniques incluent douleur, érythème cutané, oedème de la glande, fièvre et parfois pus visible à l'ostium. En l'absence de doute, aucun examen n'est utile en dehors des prélèvements. Une échographie est réalisée en cas d'incertitude diagnostique ou de signes de complications. Le traitement des sialadénites bactériennes repose sur une antibiothérapie probabiliste secondairement adaptée pour une durée de dix jours. Le germe le plus fréquent est Staphylococcus aureus. La réhydratation est primordiale, surtout chez les sujets âgés. Le traitement des sialadénites virales, résolutives en huit à quinze jours, est symptomatique. Si l'évolution est le plus souvent favorable, le risque de complications graves impose un diagnostic rapide et un traitement adapté.

Expression, Prognostic Value and Correlation with HPV Status of Hypoxia-Induced Markers in Sinonasal Squamous Cell Carcinoma.

(1) Background: In head and neck squamous cell carcinoma, tumor hypoxia has been associated with radio/chemoresistance and poor prognosis, whereas human papillomavirus (HPV)-positive status has a positive impact on treatment response and survival outcomes. The aim of this study was to evaluate the expression and the potential prognostic value of hypoxia-induced endogenous markers in patients treated for squamous cell carcinoma of the nasal cavity and paranasal sinuses (SNSCC), and their correlation with HPV status. (2) Methods: In this monocentric study, patients treated in a curative intent for a SNSCC were screened retrospectively. Protein expression of CA-IX, GLUT-1, VEGF, VEGF-R1, and HIF-1α was determined by immunohistochemical staining, scored, and then correlated with overall survival (OS) and locoregional recurrence free survival (LRRFS). HPV status was assessed and correlated with hypoxic markers. (3) Results: 40 patients were included. A strong expression of CA-IX, GLUT-1, VEGF, and VEGF-R1 was detected in 30%, 32.5%, 50%, and 37.5% of cases, respectively. HIF-1α was detected in 27.5% of cases. High CA-IX expression was associated in univariate analysis with poor OS (p = 0.035), but there was no significant association between GLUT-1, VEGF, VEGF-R1, and HIF-1α expression, and OS/LRRFS. There was no correlation found between HPV status and hypoxia-induced endogenous markers (all p > 0.05). (4) Conclusions: This study provides data on the expression of hypoxia-induced endogenous markers in patients treated for SNSCC and underlines the potential role of CA-IX as a prognostic biomarker for SNSCC.

Middle Ear Osteoma Causing Mixed Hearing Loss: A Case Report.

Osteomas of the middle ear are rare benign tumors. Their consequences and symptoms are due to their specific location, such as the promontory or the epitympanum and their contact with the facial nerve, the semicircular canal, the ossicles, and the oval or round windows. We report a very unusual case of middle ear osteoma (MEO) in a 23-year-old male patient causing a right mixed hearing loss by contacting and overwhelming the incus and stapes. The lesion was also closely attached to the tympanic portion of the fallopian canal. Since the stapes was not clearly visible behind the lesion, careful observation was preferred to surgery owing to the high risk of inner ear damage and facial palsy with removal of the lesion. MEOs are rarely situated at this critical site. Regular clinical and computerized tomography monitoring is warranted to check their growth. This case also supports the etiological theory of chronic middle ear inflammation causing osteomas.
