“…5 Few of our patients presented with tumors of massive size (10 cm × 12 cm). In Rzepakowskaet al 3 study the majority of tumors 39 (57.4%) were located in the prestyloid space. There were 11 (16.2%) postyloid tumors and the same number of tumors involving both localizations.…”

“…In current study showed that female was predominate 59.4% and male 40.6%. Rzepakowska et al 3 reported there were 46 (67.6%) women and 22 (32.4%) men with a mean age of 52.2 years (age range 33-92 years). Regarding sign and symptoms the most common symptoms of neurogenic tumors were a neck swelling (100%), sorethroat (34.38%), dysphagia (28.13%) and dysphonia (25.0%) and intraoral mass (18.75%).…”

“…It is described as an inverted pyramid with the floor of the pyramid at the skull base and the apex at the level of the greater cornu of the hyoid bone 2 . Parapharyngeal tumors are rare pathologies that comprise approximately 0.5% -1.5% of all head and neck tumors 3 . Eighty percent of them are benign and 20% are malignant.…”

Background: Parapharyngeal tumours are rare accounting for 0.5-1.5% of all head neck tumuors. The anatomy of the Parapharyngeal space (PPS) is responsible for a wide variety of tumours arising from PPS. Objective: Evaluation of the strategy for parapharyngeal tumor surgery based on preoperative symptoms, clinical signs, imaging investigations and histopathology. Methodology: This retrospective study was carried out in the Department of Otolaryngology and Head Neck surgery in Bangabandhu Sheikh Mujib Medical University (BSMMU) included 32 patients were underwent surgery for primary parapharyngeal tumors between January 2018 and December 2019. Informed written consent was obtained from the patients prior to their inclusion in the study. In regard to histologic type there were 21 cases salivary gland origin tumors and 11 of neurogenic tumors. The following data were evaluated preoperative symptoms, histological type, surgical approach and complications patients were evaluated following a laboratory investigations. Results: The most common symptoms of these tumors were a neck swelling. Total of 18 tumors were located in the prestyloid and poststyloid space cases were located 10(31.25%) and 4(12.50%) in the pre and poststyloid. Majority 12(37.50%) was found pleomorphic adenomaof deep lobe of parotid gland followed by 6(18.75%) were schwannoma,4(12.50%) were neurofibroma, 3(9.38%) were ectopic salivary gland tumor,2(6.25%) were mucoepidermoid carcinoma, 2(6.25%) were adenocarcinoma. First bite syndrome and lower lip palsy were common post operative complications. Transcervical approach was the most often performed approach in this study (56.25%). Conclusion: Parapharyngeal tumours most often derived from parotid gland. Most of them are non-malignant. Pleomorphic adenoma is the more common. Surgical resection being the main stay of treatment. Tumours of this complex anatomy call for careful preoperative planning and great skill for selecting the right approach and for management with minimal morbidity and recurrence.

“…14,[25][26][27][28] In addition, the treatment strategy for pleomorphic adenoma or schwannoma, such as approach selection, extracapsular/intracapsular dissection, and surgical-related neurovascular morbidity, is clearly different. 23,24,29 As pattern 1 was closely related to pleomorphic adenoma and pattern 2 to schwannoma, this new classification helps in generating a detailed preoperative plan with regard to the options of approaches, possible complications, and expected outcomes. We consider that the classification of tumors, as we described above, is valuable for planning surgical strategies.…”

Objective: Nearly half of parapharyngeal space (PPS) tumors present as an intraoral mass, which is diagnostically challenging. In this study, we studied whether preoperative growth patterns were associated with histopathological diagnosis for planning surgery. Methods: We performed a cross-sectional study in patients with PPS tumors. A simplified classification scheme based on intraoral tumor growth patterns (patterns 1 and 2) was then proposed. In pattern 1, tumors bulge submucosally to the oropharynx from the soft palate, with the center convexity above the uvula. In pattern 2, tumors bulge submucosally to the oropharynx from the lateral oropharynx wall, with the center convexity below the uvula. The association of this classification with postoperative histopathological diagnosis and surgical-related events was studied. Results: Twenty-two patients were enrolled in this study (12 with pattern 1, 10 with pattern 2). Of these, 91.7% (11/12) of pattern 1 tumors were salivary gland tumors ( P < .001), and 90% (9/10) of pattern 2 tumors were neurogenic ( P < .001). Pattern 2 tumors had fewer bleeding complications or needed external approaches when a transoral approach was chosen. Conclusions: This new classification of PPS tumors facilitates the prediction of salivary gland and neurogenic tumors and can improve the accuracy of preoperative radiologic diagnosis. This system will be helpful for planning surgical interventions, such as implementing transoral approaches.
