Surgery for tumors of the parapharyngeal space PPS) requires adequate exposure to identify and protect vital structures. Thus transcervical and transcervical-transparotid approaches to the PPS may be enhanced by mandibulotomy for better visualisation. We have chosen this approach with single mandibulotomy just in front of foramen mentale and without lip incision. We present a 39 years old male ...
A 44-years-old male presented with right infraauricular swelling. It had been four months since he was aware of the mass. He had not felt any pain or tenderness. Computed tomograpy demonstrated a homogenous, regular surfaced mass located in the prestyloid and poststyloid parapharyngeal space. Its density was concordant with lipomatous tissue, so it was considered to be an infiltrating paraphary...
Tumors of the parapharyngeal space are rare accounting approximately for 0.5% of all head and neck tumors. In the retrostyloid space, schwannomas are a more common finding, in contrast to other tumors. Usually, they present with a variety of slight symptoms until they grow in size and compress surrounding organs. Surgical treatment of parapharyngeal space tumors is difficult; due to the anatomi...
We performed percutaneous CT-guided needle biopsies with a transfacial approach in the diagnosis of lesions of the parapharyngeal region. Via the buccal space, core needle biopsy specimens were obtained in eight patients with known parapharyngeal abnormalities identified by CT and/or MR imaging. In all cases, sufficient tissue was obtained to provide a definitive histologic diagnosis. There wer...
Unusual MR and CT findings of an inflammatory pseudotumor in the parapharyngeal space of a 73-year-old woman are reported. The mass was hypointense on T1- and T2-weighted images and demonstrated ring enhancement after contrast medium injection. Punctated calcifications were scattered at the periphery. Inflammatory pseudotumors in the parapharyngeal space are rare, and only three cases have been...
Background. Parapharyngeal space is one of potential facial planes for neoplasms and infections and represents less than 1% of all head and neck tumours. Occurrence of the pleomorphic adenoma in the parapharyngeal space is a rarity. Case Presentation. Here, three giant pleomorphic adenomas of different sizes occupying the parapharyngeal space in three patients are reported. Extensive preoperati...
The clear cell sarcoma of tendons and aponeuroses (CCSTA) is a rare soft tissue sarcoma in the head and neck region and parapharyngeal space. Over 95% of CCSTAs present in the extremities, with the head and neck region (1.9%) being an unusual site. This study presents an additional case of CCSTA of the head and neck region involving the parapharyngeal space in a 48-year-old men and review of th...
Parapharyngeal pleomorphic adenoma (PA) is a benign tumor of the salivary glands. We report a rare case of giant benign parapharyngeal PA with intracranial extension in a 69-year-old male who presented with aural fullness. Magnetic resonance imaging (MRI) showed a large, lobulated, well-defined mass in parapharyngeal space with erosion of the base of the middle cranial fossa and extension to th...
BACKGROUND Carcinoma of the thyroid gland is one of the most commonly encountered endocrine malignancies. Papillary carcinoma is the most common histological type, and its spread is usually lymphatic. About 30-80% patients with papillary carcinoma develop lymphatic metastases. CASE REPORT We present here the case of a 70-year-old female patient who had undergone total thyroidectomy 10 years p...
