Sinus headache and nasal disease
Stephen D. Silberstein, Richard B. Upton, Peter J. Goadsby in Headache in Clinical Practice, 2018
Sinus infection can result in acute suppurative meningitis, subdural or epidural abscess, and brain abscess. In addition, osteomyelitis and subperiosteal abscess can occur. Infection of the ethmoid, and, to a lesser extent, the sphenoid sinuses, is responsible for orbital complications, which include edema, orbital cellulitis, and subperiosteal and orbital abscess.7 A mucocele is a mucus-containing cyst located in the sinuses. These are most common (and benign) in the maxillary sinus (mucus retention cyst). Those located in the frontal, sphenoid, or ethmoid sinus can enlarge and erode into the surrounding structures. A pyocele is an infected mucocele.8,present with purulent nasal discharge, which is not characteristic in adults. Fever is infrequent, even with acute sinusitis, and is usually associated with complicated acute sinusitis.30,31
Frontal Sinus Fractures

After exposure of the fracture, anterior table fragments should be removed with the orientation preserved. The remainder of the anterior table should be removed as necessary to facilitate stripping of all mucosal surfaces. A 3 to 5 mm diamond burr allows complete removal of mucosal elements without risking abrupt penetration of the remaining thin bone, as could potentially occur using a cutting burr. All inner surfaces of the frontal sinus are abraded to remove traces of mucosa in the pits of Breschet. If mucosa is left behind, it has the potential to continue to secrete mucus that would have no route for drainage. A mucocele or mucopyocele is a possible sequela of retained mucosa and may not be evident for several years after the repair.
The gastrointestinal system
C. Simon Herrington in Muir's Textbook of Pathology, 2020
There are three pairs of major salivary glands – parotid, submandibular, and sublingual – and numerous intraoral minor salivary glands. The most common lesion of minor salivary glands is the mucocele. The lesion is most often seen on the lower lip and is frequently due to leakage of mucus from a damaged duct (mucus extravasation cyst – Figure 10.14). A cyst-like cavity forms and consists of the escaped mucus and macrophages surrounded by granulation tissue. A ranula is a larger variant that occurs in the floor of the mouth and usually involves the sublingual glands. Alternatively, a mucous retention cyst results from the accumulation of mucus within a blocked salivary duct.
Gold laser removal of a large ductal cyst on the laryngeal surface of the epiglottis

A 55-year-old man was referred to the clinic after a difficult intubation during an implantable cardioverter-defibrillator placement surgery, where a mass was reportedly blocking the view to the glottis. The patient described a prior “clothesline injury” that occurred at age 9 with no associated stridor or difficulty breathing. Postinjury, he experienced a peculiar and muffled dysphonia with no signs of dyspnea or dysphagia. A computed tomography scan confirmed the presence of a large mucocele in the supraglottic region (Figure 1). Flexible laryngoscopy revealed a mass originating at the right laryngeal edge of the epiglottis extending to the right aryepiglottic fold (Figure 2a). Although the mass was larger than most ductal cysts, no imminent airway obstruction was present. Normal arytenoid and vocal cord mobility were noted despite acquiring only a partial view of the glottis due to the obstruction caused by the mass.
Beyond the commonest: right lower quadrant abdominal pain is not always appendicitis

The mucoceles occur due to abnormal excessive accumulation of mucin within the appendicular lumen, leading to excessive cystic distention of the appendix on top of different pathologies. We had been confronted with two cases (0.2%) of appendicular mucocele (Figure 4) and only one (0.1%) as low grade mucinous cystic tumor (Figure 5). Both lesions were clinically presented as right iliac fossa distension and dull aching pain, with minimal leukocytosis. Pathologically, the appendicular mucocele could be subdivided into different types; according to the underlying etiology. It could be due to simple inflammatory retention mucocele, which may occur due to appendicular lumen obstruction by a faecolith or mucosal hyperplasia. Also, it may be mucinous cystadenoma, which is the most common or less commonly mucinous cystadenocarcinoma. [16,17]
Frontoethmoidal mucocele presenting with ocular manifestations

Mucocele of the paranasal sinuses is a slowly expanding benign lesion developing when there is impeded physiological drainage of the mucous produced by the epithelial lining of the paranasal sinuses, at the sinus ostium, which is an opening that connects the sinus to the nasal cavity.2007 Aetiologies of ostial occlusion include infection, allergy, trauma, previous surgery, benign neoplasm (osteoma or fibrous dysplasia), and malignant or metastatic tumours.2003 Mucoceles commonly develop in the frontal sinus (70–80 per cent), followed by the ethmoid (25 per cent), frontoethmoidal (10–14 per cent), and maxillary (three per cent or less) sinuses.1978
