      Female, 69, long time dysphagia, left oropharyngeal swelling. CT and MRI -7,2cm parapharyngeal space tumor on the left, pre-styloid, occluding 70% of pharynx – suggestive of pleomorphic adenoma. According to the literature, tumors of the parapharyngeal space are rare. It was reported previously that only percent of all head and neck tumors are located in the parapharyngeal space [ 2 ]. Neurogenic tumors more often occur in the poststyloid compartment of the parapharyngeal space than in the prestyloid compartment [ 4 ].Cited by: 1. Parapharyngeal space (PPS) tumors are very rare, representing about % of head and neck neoplasms. An external surgical approach is mainly used. Several recent papers show how transoral robotic surgery (TORS) excision could be a prospective tool to remove mainly benign lesions in PPS; no cases of neurogenic tumors from the retrostyloid space treated with TORS have been by:

Parapharyngeal space Tumors of the parapharyngeal space book are rare and account for % of head and neck tumors, 80% benign and 20% malignant; Salivary gland neoplasms (benign to malignant ratio ): majority of parapharyngeal space tumor, mostly in the prestyloid space.

Neurogenic neoplasms: second most common, mostly in the poststyloid space. In order to safely resect tumors located in the narrow parapharyngeal space, indocyanine green (ICG) fluorescence imaging for navigation surgery is proposed recently.

Parapharyngeal Space Tumors. Synonyms. Definition. The parapharyngeal space (also known as the lateral pharyngeal or pharyngomaxillary space, hereafter referred to as the PPS) is a potential space in the shape of an inverted pyramid that lies within the deep neck just lateral to the superior pharynx.

Parapharyngeal Tumors of the parapharyngeal space book is a potential space in the neck extending from skull base to the greater cornu of hyoid bone.

Salivary gland cancer is rare but the most frequent malignant tumor in the parapharyngeal space. Understanding the anatomy of the parapharyngeal space is important to understand the advantages, limitations, and risks of the different surgical approaches to the parapharyngeal : Orlando Guntinas-Lichius.

Two surgical procedures have been used by the author to treat 44 tumors in the parapharyngeal space. The cervical‐parotid approach was used in 35 patients, and the cervical‐parotid approach with midline mandibulotomy was used in 9 patients.

Parapharyngeal space tumors are typically asymptomatic and patients become aware of them only when a bulge develops in the palate or sidewall of the throat near the tonsils. The vast majority of these tumors are benign. Oftentimes the diagnosis is made on the basis of a scan performed for other reasons and an asymptomatic mass is identified.

Multiple approaches have been described in the literature for the extirpation of these by: Magnetic resonance (MR) imaging characteristics of 40 tumors involving the parapharyngeal space and the upper part of the neck were reviewed.

These lesions could be classified as being either hypervascular (glomus tumors or metastatic kidney, thyroid, or venous hemangiomas) or hypovascular (salivary gland tumors, neurogenic tumors, lymphomas, sarcomas).Cited by: Parapharyngeal Space Tumors.

When the tumor is large, it extends into the parapharyngeal space and then difficulties arise. These have been described as “dumbbell” or round tumors.

It has a waist-like constriction at the area of the stylomandibular ligament, thus assuming a. Parapharyngeal space tumors by J. Shah 1.

The parapharyngeal space, also known as the prestyloid parapharyngeal space, is a deep compartment of the head and neck around which most other suprahyoid fascial spaces are arranged. It consists largely of fat, neurovascular structures, and, in some definitions, the retromandibular part of the deep lobe of the parotid gland.

Tumors that originate in the parapharyngeal space are rare and account for less than % of all head and neck neoplasms. Approximately 80% of these tumors are benign, and the most common origins. parapharyngeal space tumors 1.

Surgical management of parapharyngeal space tumors: A year review. This tumor originates from the carotid bulb area and splays both carotid arteries that can be clearly demonstrated in scans. The nerve sheath tumors arising from the vagus and sympathetic chain are located posterior to the carotid vessels.

It is essential to remember that tissue diagnosis is not routinely required in parapharyngeal space lesions. The parapharyngeal space (PPS) is a complex anatomic space that is commonly described as an inverted pyramid, with the temporal bone located at the base and the hyoid bone at the apex.

The parapharyngeal space (PPS) is a rare site for neoplasms in the head and neck, representing only % of head and neck tumors. Most commonly of parotid and neurogenic origin, tumors of the PPS are histologically diverse.

Only 5 liposarcomas of the PPS have been previously reported Cited by:   • We retrospectively studied tumors of the parapharyngeal space treated at the Baylor College of Medicine Affiliated Hospital System, Houston, from to Of the 42 lesions, 30 (%) were benign and 12 (%) were malignant.

The parapharyngeal space (also termed the lateral pharyngeal space), is a potential space in the head and the neck.

It has clinical importance in otolaryngology due to parapharyngeal space tumours and parapharyngeal abscess developing in this area.

Shahinian M.D., C. Dornier, M.D., U. Fisch, M.D. Abstract Tumors of the parapharyngeal space, although mostly benign in their histopathology, present a challenge to the surgeon due to the limited access. The parapharyngeal space is particularly important in otolaryngology, a branch of medicine that concerns the throat disorders, as well as that of the head, ears, nose and neck.

It is prone to tumors of neurogenic and salivary engines, as well as accumulations of pus known as abscesses. The 23 benign tumors consisted of 11 pleomorphic adenomas, 5 schwannomas, 2 paragangliomas, 2 Warthin tumors, 1 oncocytoma, 1 hamartoma, and 1 osteochondroma.

The surgical access to parapharyngeal space tumours is limited and difficult. This is because it is a blind space enclosing important neurovascular structures with the tumour occasionally arising from the nerve sheath itself. In view of the above, a careful meticulous dissection is required via a safe approach like theFile Size: 1MB.

Parapharyngeal space tumors account for % of all head and neck masses, (1) and most clinicians will see only a small number of cases during their careers. In a review by Riffat et al, most of the tumors (82%) were benign and 18% were malignant; the most common primary lesions were salivary gland lesions (45%) and neurogenic lesions (41%).
