This article presents the case of a woman in her 40s with a swelling in her left cheek. CT revealed an intramuscular lesion within the masseter, suggestive of a venous malformation. Surgical treatment was carried out with intraoral access to the lesion, allowing for complete removal, resulting in temporary swelling and trismus. There was no facial paralysis. We discuss information on IH in the head and neck and their surgical approaches.<\/jats:p>","DOI":"10.1136\/bcr-2024-261382","type":"journal-article","created":{"date-parts":[[2024,9,16]],"date-time":"2024-09-16T14:00:13Z","timestamp":1726495213000},"page":"e261382","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Cavernous haemangioma of the masseter muscle: transoral approach"],"prefix":"10.1136","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5132-1793","authenticated-orcid":false,"given":"Pedro Polastri Lima","family":"Peixoto","sequence":"first","affiliation":[{"name":"Ophthalmology, Otorhinolaryngology, Head and Neck Surgery Department, Universidade de S\u00e3o Paulo Hospital das Cl\u00ednicas da Faculdade de Medicina de Ribeir\u00e3o Preto, Ribeirao Preto, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paulo Ot\u00e1vio Alves","family":"Ashidani","sequence":"additional","affiliation":[{"name":"Ophthalmology, Otorhinolaryngology, Head and Neck Surgery Department, Universidade de S\u00e3o Paulo Hospital das Cl\u00ednicas da Faculdade de Medicina de Ribeir\u00e3o Preto, Ribeirao Preto, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcos Mello","family":"Ness","sequence":"additional","affiliation":[{"name":"Ophthalmology, Otorhinolaryngology, Head and Neck Surgery Department, Universidade de S\u00e3o Paulo Hospital das Cl\u00ednicas da Faculdade de Medicina de Ribeir\u00e3o Preto, Ribeirao Preto, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luiz Carlos","family":"Conti de Freitas","sequence":"additional","affiliation":[{"name":"Ophtalmology, Otolaryngology, Head and Neck Surgery, University of Sao Paulo Faculty of Medicine of Ribeirao Preto, Ribeirao Preto, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2024,9,16]]},"reference":[{"key":"2025082623523292000_17.9.e261382.1","doi-asserted-by":"crossref","first-page":"218","DOI":"10.7181\/acfs.2021.00283","article-title":"A hemangioma in the masseter muscle: a case report","volume":"22","author":"Park","year":"2021","journal-title":"Arch Craniofac Surg"},{"key":"2025082623523292000_17.9.e261382.2","doi-asserted-by":"crossref","first-page":"115","DOI":"10.7181\/acfs.2021.00087","article-title":"Intramuscular hemangioma in the zygomaticus minor muscle: a case report and literature review","volume":"22","author":"Wee","year":"2021","journal-title":"Arch Craniofac Surg"},{"key":"2025082623523292000_17.9.e261382.3","doi-asserted-by":"crossref","DOI":"10.1136\/bcr-2022-252579","article-title":"Masseteric giant capillary haemangioma: a bulky mass treated with scarless and minimally invasive surgery","volume":"15","author":"Cascino","year":"2022","journal-title":"BMJ Case Rep"},{"key":"2025082623523292000_17.9.e261382.4","doi-asserted-by":"publisher","DOI":"10.1097\/SCS.0000000000000461"},{"key":"2025082623523292000_17.9.e261382.5","doi-asserted-by":"crossref","DOI":"10.2340\/actadv.v103.4432","article-title":"Characteristics, Natural Course and Treatment of Intramuscular Capillary-type Haemangioma: A Systematic Literature Review","volume":"103","author":"Orly","year":"2023","journal-title":"Acta Derm Venereol"},{"key":"2025082623523292000_17.9.e261382.6","first-page":"393","article-title":"Clinicopathological characteristics of 16 cases of intramuscular hemangioma capillary type","volume":"52","author":"Xue","year":"2023","journal-title":"Zhonghua Bing Li Xue Za Zhi"},{"key":"2025082623523292000_17.9.e261382.7","unstructured":"International Society for the Study of Vascular Anomalies .
