“…Under physiological conditions, air and oral secretions are prevented from flowing back into the parotid duct and gland by various anatomical mechanisms: contraction of the buccinator muscle [8], the diameter of the duct orifice is less than that of the duct itself [7,9], the duct orifice is slit-shaped and is sealed off by mucosal folds when intraoral pressure increases [4,5], cheek inflation increases duct angle both between the oral submucosa and buccinator muscle and between the buccinator and the subcutaneous tissue alongside the masseter muscle.…”

Background Pneumoparotid is a rare cause of parotid gland swelling. It is due to reflux of air through Stensen’s duct into the parenchyma of the parotid gland. Case presentation A case of self-induced pneumoparotid in a 12-year-old boy is reported. The diagnosis was primarily considered after careful history taking with special attention on the patient’s habits, and it was confirmed by computed tomography. Conclusion Pneumoparotid is a rare but well-documented clinical entity. It should be included in the differential diagnosis of parotid gland swelling.

“…As possible causes of appearances and recurrences of parotid involvement, there is a weakening of the buccinator muscle that does not prevent the retrograde flow toward the Stensen duct and the presence of an abnormal dilation in the ducts path. 8 It is suspected that at the submandibular level, the possible causes would be a dilatation of the duct as anatomical variation or secondary to a trauma.…”

“…Tomography report stated that inside the submandibular salivary gland, a hypodense image, gas density (-1100 UH) was observed, dilating the gland and also the Wharton's duct, measuring 3.95 Â 4.47 Â 4.68 cm considering emphysematous sialoadenitis (►Figs. [4][5][6][7][8][9].…”

There are multiple etiologies for facial subcutaneous emphysema, including facial trauma, dissection of air along facial planes from a pneumomediastinum, infection, and entry of air through defects in teeth due to decay, trauma, or dental procedure. In addition, air can be forced through lacerations of the oral or pharyngeal mucosa by increased intraoral pressure. An infrequently reported cause of subcutaneous emphysema is autoinsufflation of the parotid duct with extravasation of air into the surrounding tissue. In this report, the authors present a 14-year-old patient treated at the Department of Oral and Maxillofacial Surgery of the Hospital Escuela Universitario due to an increase in size in the buccal region and left masseterine space of 2 months of evolution. Presenting with a sudden evolution, without any possible explanation, which caused displacement of adjacent structures without damage to the bone or surrounding tissues. After a series of echographic and tomographic studies, it showed that inside the submandibular gland there was a hypodense image with gas density (-1100 UH) expanding the gland and its respective excretory duct.

“…Several predisposing factors for pneumoparotid disease have been reported in the literature. These factors include a patulous duct, congenital abnormality, hypotonia of the buccinator muscle around the papilla, hypertrophy of the masseter muscle, self-injury to the Stensen's duct, decreased production of saliva with increased mucous secretion, transient obstruction of Stensen's duct by mucous plugs causing decreased salivary flow, diagnostic maneuvers such as sialography [21,23,39,48,90], blunt trauma to the cheek [24], pleomorphic adenoma [36], and treatment for duct stenosis with stent implantation or transoral duct surgery [162]. Sánchez et al [16] reported the case of a 15-year-old girl who injured herself by self-instrumentation of the parotid gland orifice with hairpins or safety pins.…”

Pneumoparotid describes the presence of retrogradely insufflated air within the Stensen's duct and/or parotid gland. It is a rare condition with variable causative factors. This study aimed to clarify the clinical characteristics of pneumoparotid; reports in all languages were evaluated fol-lowing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement 2020. A literature search was conducted using electronic medical databases (PubMed, Scopus, Web of Science, EBSCO, Ovid, Google Scholar, SciElo, LILIACS, and others) from 1890 to June 30, 2022. One hundred and seventy patients (mean age; 28.4 years) from 126 studies were reviewed. Common symptoms included swelling (84.7%) and pain (35.9%). Characteristic findings were crepitus in the parotid region (40%) and frothy saliva from the orifice (39.4%). Common etiologies included abnormal habits such as blowing out the cheeks (23.5%), idiopathic (20%), self-induced (15.9%), playing wind instruments such as trumpets or flutes (8.8%), and diseases inducing coughing or sneezing (8.2%). Treatments included antibiotic therapy (30%), behavioral therapy to avoid continuing causative habits (25.9%), psychiatric therapy (8.2%), and surgical procedures (8.2%). Treatment should be individualized based on the etiology. However, the etiology was not identified in 20% of patients. Further detailed data from larger samples are necessary to better understand and improve the recognition of this entity.
