Follicular dendritic cell sarcoma (FDCS) is an extremely rare malignancy arising from follicular dendritic cells accounting for less than 0.4% of all soft tissue sarcomas. While it can manifest in various anatomical locations, its occurrence in the nasopharynx is particularly uncommon with only 10 reported cases in the English literature. This case report describes a 45-year-old woman who complained of persistent neck swelling, nasal obstruction, and left ear fullness. Imaging showed a nasopharyngeal process and cervical lymphadenopathy. Biopsies confirmed FDCS. Treatment included chemotherapy and radiation, resulting in a favorable outcome with no recurrence during 2 years of follow-up.

Objective: This study aimed to investigate the optimal head position (OHP) following intratympanic injection, a critical intervention in treating inner ear disorders. Identifying OHP is essential to maximize drug retention in the middle ear, thereby significantly enhancing the therapeutic efficacy by mitigating the significant issue of injectate leakage through the eustachian tube (ET). Exploratory various positions of ET orifice and round window (RW) were investigated and associated with head movements. Methods: Twenty-two (10 males and 12 females) anonymized high-resolution computed tomography (HRCT) datasets of patients without structural ear disease were selected from January 2022 to December 2022 in the study. The subjects were categorized into two groups: children (≤18 years) and adult group (>18 years). The reconstruction of the ET orifice and RW from HRCT were analyzed using Mimics software and the distances from the center point of ET orifice or the center point of RW to the reference plane were defined as distance of ET orifice (DET) and distance of RW (DRW). Results: In the supine position, the OHP for intratympanic injection was 23°of pronation and 24° of posterior extension, and the maximum distance between the ET orifice and RW (DET-RW) was 9.29 ± 2.13 mm. As the head position extended posteriorly beyond 43°, DET was relatively high compared with DRW, resulting in the OHP a fully posteriorly extended 90° of the head being the optimal position with DET-RW of 2.13 ± 1.60 mm in the supine position, however, it is not realized in human beings. Moreover, the OHP had no obvious relevance corresponding to age following intratympanic injections. Conclusion: Our study suggested that OHP after intratympanic injections treatment consists of supine position, along with a slight pronation and posterior extension.

Since the introduction of effective chemotherapy, the development of new diagnostic tools, and raising public awareness of the devastating health, social, and economic consequences of tuberculosis (TB), the frequency of this disease has decreased. Pulmonary TB is the most common form of the disease, but TB bacilli can spread to other organs including lymph nodes, and the oral cavity especially the tongue with very unusual features. Oral lesions, although rare, are very important for early diagnosis and interception of primary TB. The bacteriological and histopathological results are important to confirm the diagnosis. Oral TB lesions may be either primary or secondary. The evolution is generally good under a medical treatment. A 35-year-old patient was admitted to our department for an ulcerous tumor in the lateral border of his tongue. The biopsy of the ulceration confirmed the diagnosis of TB. A concomitant pulmonary localization has been found. This case report aims to attract the attention of TB, which can be located in some uncommon regions, and have unusual clinical presentations.

Objectives: To avoid postoperatively acquired cholesteatoma, whether there was any squamous epithelial tissues residue around the tip of the malleus handle, and the need to remove these tissues were explored. Methods: This prospective study enrolled 197 patients who underwent endoscopic tympanoplasty. A postoperative pathological evaluation of the tissue around the tip of the malleus handle was performed to determine the presence of squamous epithelium. Analyzed correlation of epithelial remnants with exposure of malleus handle and microbial infection of middle ear. Results: The detection rate of squamous epithelial retention around the tip of the malleus handle differed significantly among patients with adhesive otitis media (AdOM), acquired cholesteatoma, and chronic suppurative otitis media (CSOM). The detection rate was significantly higher in the acquired cholesteatoma group than in the AdOM and CSOM groups (P < .001). The rate of squamous epithelial retention around the tip of the malleus handle was not significantly associated with microbial infection of the middle ear, the surgical side (P = .672), dry or wet ear status (P = .702), or exposure of the malleus handle (P = .06). Conclusions: In patients with acquired cholesteatoma, AdOM, or COM with severe tympanic sclerosis, the tissue around the tip of the malleus handle should be removed completely. For patients with simple COM, that is, without tympanic sclerosis or keratinizing stratified squamous epithelium at the edge of the perforation, the tissue can be retained.
目的:为避免术后获得性胆脂瘤,探讨耳郭柄尖周围是否有鳞状上皮组织残留,以及是否需要切除这些组织。方法:这项前瞻性研究共纳入了 197 名接受内窥镜鼓室成形术的患者。术后对鼓膜柄尖周围的组织进行了病理评估,以确定是否存在鳞状上皮。分析上皮残留与鼓槌柄暴露和中耳微生物感染的相关性。结果:粘连性中耳炎(AdOM)、获得性胆脂瘤和慢性化脓性中耳炎(CSOM)患者耳郭柄尖周围鳞状上皮残留的检出率有显著差异。获得性胆脂瘤组的检出率明显高于 AdOM 和 CSOM 组(P < .001)。鼓室柄顶端周围鳞状上皮滞留率与中耳微生物感染、手术侧(P = .672)、干耳或湿耳状态(P = .702)或鼓室柄暴露(P = .06)无显著相关性。结论对于后天性胆脂瘤、AdOM 或伴有严重鼓室硬化的 COM 患者,应完全切除鼓槌柄尖周围的组织。对于单纯的 COM 患者,即穿孔边缘没有鼓室硬化或角化分层鳞状上皮的患者,可以保留组织。

Primary intraosseous hemangiomas of the maxillofacial region are rare lesions that comprise less than 1% of all osseous tumors. A review of the literature on primary intraosseous hemangiomas of the facial bones revealed a limited number of publications, much of which was largely limited to case reports. This case report summarizes the workup and surgical treatment of a 37-year-old female with a primary intraosseous hemangiomas of the left maxillary bone. The image, histology, treatment, and literature are reviewed.

Objectives: To analyze trends in error publication in the top Otolaryngology-Head and Neck Surgery (OHNS) journals. Methods: A retrospective bibliometric analysis utilizing journal-specific search engines of the top 30 OHNS journals (by impact factor) were queried for "errata OR erratum OR corrigenda OR corrigendum OR correction OR corrections," utilizing errors published between 2000 and 2023. Corrections were classified into "erratum" for errors originating from the journal and "corrigendum" for errors originating from the author. Error severity was categorized as trivial, minor, or major, based on the magnitude of their impact on outcomes or their interpretation by the reader. Results: Of the 739 analyzed errors, 62.5% (n = 462) were errata and 37.5% (n = 277) corrigenda, averaging 26.39 (±27.5) errors per journal. There was no correlation between impact factor and error occurrence (P = .979). Trends demonstrated growing numbers of errors published over the years. Mean duration between the publication date of the original article and the error was 10.8 months (±19.4 months), but there was no significant correlation between impact factor and this duration (P = .953). Most corrected articles were original research articles (n = 568, 76.9%), predominantly with the first author from the United States (n = 262, 36.1%). Most errors involved authorship (n = 273, 36.9%) and were "Trivial" in severity (n = 544, 73.6%). However, 72 (9.7%) errors were "Major" and altered the article's findings or interpretation significantly. Conclusion: A multitude of errors exist in the otolaryngology field. Despite most being insignificant and affecting authorship, roughly 10% significantly affect an article's conclusions/outcomes.Level of Evidence: 4.
