“…Enhanced CT is useful for analysis of tumor location and to preoperatively establish a method of approach for surgery (10). Three dimensional-CT angiography is indicated when the tumor is suspected to be a carotid body tumor from its location, in order to evaluate its vascularity and confirm the diagnosis (21).…”

Abstract. The present study aimed to establish a strategy for parapharyngeal space (PPS) tumor surgery based on preoperative symptoms, clinical signs, imaging and histological examination. A retrospective cohort study was conducted with 29 adult patients who underwent surgery for primary PPS tumors from 2008-2015. The following data was obtained: Preoperative symptoms of the patient, histological type of the tumor, surgical approach and complications. Of the 29 patients who underwent surgery to remove a PPS tumor, 16 presented with neurogenic tumors and 13 with salivary gland tumors. The most common symptom was the presence of a neck mass. Preoperative computed tomography and magnetic resonance imaging were performed to evaluate the size and location of the tumors. The majority of the salivary gland tumors were located in the prestyloid space, whereas all neurogenic tumor cases were poststyloid. A total of 21 of the 29 patients (72.4%) underwent a preoperative fine needle aspiration (FNAC) examination. FNAC contributed to preoperative diagnosis in 9 of these cases (42.9%). In parotid tumors of the prestyloid space, facial nerve palsy was a common postoperative complication. In the case of neurogenic tumors, a common complication was the postoperative palsy of the nerve of tumor origin. The strategy for PPS surgery, from the preoperative diagnosis to the operative method, remains controversial. The data on pre-and postoperative symptoms, imaging and histological diagnosis, and the selection of surgical method depending on a neurogenic or salivary tumor origin in the present study indicated that improving the method of examination, carefully selecting the method of approach and accurately managing surgery leads to complete tumor removal, and that the use of nerve-preserving techniques may reduce the likelihood of complications.

“…The authors reported that they could not perform FNAB in post-styloid area tumors because of major risks and nondiagnostic samples. 11 In a study performed by Arnoson et al on 27 patients whose benign-malignant PPS tumors were confirmed with both surgery and imaging techniques, specific diagnosis were only obtained from 36% of all FNAB samples. In this study, the reliability of FNAB was reported as %92 in the diagnosis of positive and negative malignancy, and nondiagnostic sample rate was reported as %31.…”

“…Parapharyngeal space (PPS) tumors are rare lesions that comprise less than 0.5% of head and neck masses [42]. The majority of the lesions, 66.4% up to 87.3% of the cases, are benign and 18% are malignant [42,43] (Table 3). The PPS is a complex space located in the suprahyoid neck resembling a pyramid with the base formed by the skull base and the apex pointing to the greater cornu of the hyoid bone, mainly divided pre-and poststyloid space [44].…”

Head and Neck Cystic Lesions: A Cytology Review of Common and Uncommon Entities

et al. 2022

Background: Cystic lesions of the head and neck are a diagnostic challenge since they are seen in the clinical presentation of a wide variety of conditions. Herein, common and uncommon entities that present as cystic lesions in the head and neck are reviewed. Summary: In this study, peer-reviewed articles were selected using the database PubMed, Google, Google Scholar, and Scopus. Emphasis was placed on peer-reviewed articles that discuss the cytomorphology and differential diagnosis of entities that present as cystic lesions of the head and neck. In the anterior neck, both benign and malignant neoplasms can present, including papillary thyroid carcinoma (PTC), thyroid adenomatoid nodule, parathyroid cysts, and thyroglossal cysts. In the lateral neck, branchial cleft cyst, PTC, ectopic thyroid cyst, and squamous cell carcinomas (human papilloma virus and non- human papilloma virus-related) are common. Age over 40 years raises the possibility of malignancy. In the deep neck, mostly benign cystic entities occur such as a pleomorphic adenoma, paraganglioma, schwannoma, branchial cyst, epidermal inclusion cyst, and lymphoepithelial cyst. Lesions with squamous cell features can pose diagnostic dilemmas. Conclusion: Cytologic examination of head and neck cysts can provide valuable information regarding the nature of the cystic lesions. Information about anatomic site and clinical history can assist with the differential diagnoses. Ancillary studies can improve the diagnosis in some cases. Each case should be evaluated very carefully since there are a wide variety of congenital conditions, infectious/inflammatory conditions, benign neoplasms, and primary and secondary malignancies presenting as a cystic mass in the head and neck.
