“…In PPS, the most common lesion was squamous cell carcinoma, while in the carotid and masticator spaces the most common lesion was of malignant aetiology. Similar data have already been documented in the published literature [1,15]. In the retropharyngeal space, the most common aetiologies in our study were malignancy and inflammatory, both being 40%.…”

“…Latest innovations in CT imaging, for example isotropic imaging and multiplanar reconstructions, have enhanced the role of CT in the evaluation of head and neck lesions. Furthermore, CT has been shown to be more precise in bone assessment [1–5]. Computed tomography (CT) has the ability of outlining the exact location of a neck mass in a particular space outlined by neck fascias and its influence on adjacent structures.…”

“…The spaces of the suprahyoid neck region are comprised by the parotid space, retropharyngeal space, pharyngeal mucosal space, masticator space, prestyloid parapharyngeal space, post-styloid parapharyngeal space or carotid space, and prevertebral space. Space occupying lesions (SOL’s originating in any of these spaces will initially expand the respective space and then distort the neighbouring spaces, which offers the evidence regarding its place of origin [1,2]. …”

“…Additionally, CT is less susceptible to motion artefacts, has better temporal resolution, and therefore has better compliance with claustrophobic patients as compared to MRI, and can also be done in patients with MR incompatible devices. Brilliant 3-dimensional imaging is achievable using volume rendering, maximum intensity projection and shaded surface display methods, which enables the surgeon to comprehend the anatomical extent of the lesion and its relationship to adjacent structures in a much better way [1–4]. …”

“…However, this modality is extremely reliant on operator skill and has restricted fields of view. Unlike MRI, ultrasound lacks high soft tissue contrast and specificity required for tumour staging [1–5]. …”

SummaryBackgroundSuprahyoid neck lesions are difficult to assess only by means of clinical inspection and therefore imaging techniques are required to precisely evaluate suprahyoid neck spaces. The aim of this study was to evaluate the distinctive role of computed tomography in the assessment of anatomical source and pathological type of masses involving the suprahyoid neck spaces.Material/MethodsSixty patients presenting with suprahyoid neck masses underwent computed tomography of the neck. The CT findings were correlated with histopathological findings and a final diagnosis was made.ResultsOverall, male preponderance was seen except in the case of parotid space lesions where female predominance was seen. The most common aetiology was squamous cell carcinoma and the majority of cases (30%) were seen in patients aged 41–50 years. The majority of lesions were found in the pharyngeal mucosal space (n=16) with squamous cell carcinoma being the most common pathology. In the parotid space, pleomorphic adenoma and in the prestyloid parapharyngeal space, squamous cell carcinoma were the most common lesions, respectively. In the retropharyngeal space, an equal incidence of malignant and inflammatory aetiologies was seen. Abscesses were the most common lesions in the prevertebral space. The pleomorphic adenoma was the most common benign tumour and was also the second most common tumour in the suprahyoid neck spaces. CT had an excellent correlation with histopathological findings with sensitivity of 96.4%, specificity of 100%, positive predictive value of 100% and a negative predictive value of 91.67%.ConclusionsComputed tomography definitely has a major role to play in the evaluation of suprahyoid neck masses as it has an excellent correlation with post-operative histopathological diagnosis.

A woman in her 20s with a history of cystic fibrosis underwent bilateral endoscopic sinus surgery and medial maxillectomy 4 months after bilateral lung transplantation. She presented to her rhinologist for follow-up 6 weeks after surgery reporting improved nasal obstruction and olfaction, but complained of 2 weeks of throat pain and swelling. Physical examination revealed bilateral tonsillar erythema, exudate, tenderness, and peritonsillar edema. She was prescribed amoxicillin-clavulanic acid for presumed tonsillitis and began to improve. Two weeks later her symptoms returned, now accompanied by new-onset snoring and nasal obstruction. Nasal endoscopy revealed nasopharyngeal soft-tissue swelling with mucopurulent secretions on the left side. She was referred for a computed tomographic scan with contrast, which showed a rim-enhancing, multilocular hypodense collection extending from the left nasopharynx inferiorly to the level of the right palatine tonsil (Figure 1). On the basis of the radiographic findings, she was taken to the operating room urgently. Intraoperative endoscopy revealed ulceration and necrotic debris in the nasopharynx and oropharynx. Culture and biopsy specimens were obtained.

Fascial layers encountered in the lateral skull base region: A cadaveric and radiological analysis

Background In our experience, the anterior carotid sheath forms an important plane of dissection when excising temporal bone region cancers. However, its anatomical composition, relationships, and radiological appearance remains unclear. Methods Eight sides of cadaveric heads were dissected. Anatomical findings were correlated with a high‐resolution baseline T1 MRI. Results The anterior carotid sheath was formed by the tensor‐vascular‐styloid fascia, stylopharyngeal fascia, buccopharyngeal fascia (BPF), and longus capitis fascia (LCF), and appeared as a hypointense line on MRI. Not previously described, the glossopharyngeal nerve pierced the sheath 9.0 mm (SD 2.1 mm) below the skull base and traveled through its LCF and BPF layers to exit near the pharynx. Conclusion Multiple fascial layers formed the anterior carotid sheath at the skull base, and this was radiologically identifiable. Further studies are required to validate findings and investigate the role this fascial plane has in forming an effective barrier to spread of malignancy.
