Purpose: To evaluate clinical features, diagnosis, surgical management, and treatment of parapharyngeal space tumors in a single-center setting due to limited knowledge of diagnosis and treatment of parapharyngeal space.
Methods: Clinical records of 103 patients were included for the analysis of such clinical characteristics.
Results: A total of 29 different types of tumors were diagnosed after operation: 20 benign and 9 malignant. With a follow-up of 31-84 months for 90 benign cases, 84 cases had no recurrence and 6 cases were lost to follow-up. In contrast, with an 8- to 51-month follow-up for 13 malignant cases, 11 patients died and 2 were lost to follow-up. Furthermore, for postoperative complications, 3 cases had Horner syndrome, 2 had hoarseness, 2 had facial nerve dysfunction, and each for other types.
Conclusions: Surgery remains the first choice for the treatment of parapharyngeal space tumors, with the transcervical approach used for most tumors. Moreover, CT or MRI may assist in making decisions about operation schemes.

Department of Oncology, Xiang'an Hospital of Xiamen University, Xiamen, People's Republic of China.
This case report describes a 4.5-year-old girl diagnosed with a rare Undifferentiated Small Round Cell Sarcoma (USRCS) originating in the parapharyngeal space with multiple lung metastases. Diagnostic workups, including imaging, immunohistochemistry, and genetic sequencing, identified the tumor as an unclassified subtype of USRCS.

Background: Deep neck space infections (DNSI) are common, potentially life-threatening presentations in otolaryngology. Treatment is often based on the severity of presenting symptoms and surgeon preference. This study aims to evaluate the presentation and predictors of complications in patients presenting with DNSI at an Australian Otolaryngology referral centre.

Pleomorphic adenoma of the parapharyngeal space is a rare benign tumor, representing less than 1% of tumors of the parapharyngeal space. Considering the volume of the tumor, the complexity of the space and the potential difficulties of excision, an imaging work-up including at least computed tomography (CT) and/or magnetic resonance imaging (MRI), and possibly analysis of the vascular axes (angio-MRI, arteriography) is essential. Treatment of these tumors is essentially surgical.

ENT Department, Ospedali Riuniti Marche Nord, Fano-Pesaro, Italy.
Background: Extracranial schwannomas, particularly those arising from the masticator space, are rare entities. Given the challenges in pre-operative diagnosis and the potential for misdiagnosis, accurate localization and differential diagnosis are crucial for optimal surgical planning.
Case Report: A 42-year-old woman underwent a head and neck MRI for unrelated reasons and was incidentally found to have a mass in the left masticator space.

Department of Otorhinolaryngology - Head and Neck Surgery, IRCCS Azienda Ospedaliero-Universitaria di Bologna.
Purpose Of Review: The aim of this review is to investigate the most suitable surgical approach to managing parapharyngeal space (PPS) squamous cell carcinoma (SCC) metastasis.
Recent Findings: SCC metastasis in PPS are extremely rare. The PPS itself is a complex anatomical area, requiring extensive surgical experience and various surgical approaches for effective management.
