It is often confused with more common causes of parotid enlargement, such as infection, and may be self-induced or associated with increased intraoral pressure. Awareness of this entity is important to avoid misdiagnosis and inappropriate treatment. We report an adult case of self-induced pneumoparotid in a 46-year-old male who developed recurrent bilateral parotid swelling over several months due to intentional oral auto-insufflation performed to relieve temporomandibular joint discomfort and anxiety. On otolaryngology evaluation, he had mild, soft, non-erythematous parotid swelling with subtle crepitus over the left gland. Computed tomography of the head and neck demonstrated air within both Stensen\u2019s ducts, the parotid parenchyma, and the overlying facial subcutaneous tissues, with no signs of inflammation or abscess. The patient was afebrile and without leukocytosis, and a diagnosis of self-induced pneumoparotid was established. He was managed conservatively with counseling to discontinue the pressure-generating maneuvers, and no procedural intervention was required. The swelling resolved with behavior modification, and he remained free of recurrence over 3\u2009months. This case highlights pneumoparotid as an important differential diagnosis for recurrent, noninfectious parotid swelling and demonstrates that early recognition combined with targeted history-taking and conservative management can prevent unnecessary invasive treatments and serious complications, even in adult patients.<\/jats:p>","DOI":"10.1177\/2050313x261422078","type":"journal-article","created":{"date-parts":[[2026,3,31]],"date-time":"2026-03-31T15:39:23Z","timestamp":1774971563000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Conservative management of self-induced pneumoparotid in a 46-year-old male: A case report"],"prefix":"10.1177","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-6306-6220","authenticated-orcid":false,"given":"Samir","family":"Alkhouri","sequence":"first","affiliation":[{"name":"Kirk Kerkorian School of Medicine at University of Nevada, Las Vegas, NV, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Caleb","family":"Jolley","sequence":"additional","affiliation":[{"name":"Kirk Kerkorian School of Medicine at University of Nevada, Las Vegas, NV, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Claire Victoria","family":"Ong","sequence":"additional","affiliation":[{"name":"Kirk Kerkorian School of Medicine at University of Nevada, Las Vegas, NV, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kurtis","family":"Young","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology, Kirk Kerkorian School of Medicine at University of Nevada, Las Vegas, NV, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emily S.","family":"Sagalow","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology, Kirk Kerkorian School of Medicine at University of Nevada, Las Vegas, NV, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Everett","family":"Young","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology, Kirk Kerkorian School of Medicine at University of Nevada, Las Vegas, NV, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Harry H.","family":"Ching","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology, Kirk Kerkorian School of Medicine at University of Nevada, Las Vegas, NV, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2026,3,31]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.3390\/jcm12010144"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.12998\/wjcc.v12.i34.6705"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.bjoms.2014.11.019"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1002\/hed.21873"},{"issue":"6","key":"e_1_3_2_6_2","doi-asserted-by":"crossref","first-page":"555","DOI":"10.4067\/S0716-10182009000700012","article-title":"Neumoparotiditis o neumopar\u00f3tida en el ni\u00f1o: un diagn\u00f3stico diferencial a considerar (Pneumoparotitis or pneumoparotid: a differential diagnosis to consider)","volume":"26","author":"Mo\u00ebnne KB","year":"2009","unstructured":"Mo\u00ebnne KB, Cordero JT, Poli CH.
