With the evolution of endoscopic sinus surgery, the endoscopic marsupialisation has become the standard of care for these lesions. However, the external approach still has a role in selected cases of frontal sinus mucocele. The location of the mucocele and its communication with the natural outflow tract of the frontal sinus are some of the critical factors to be considered while choosing the surgical approach. We have discussed the management of three cases of frontal mucoceles having different locations and one of them having intervening septa. We emphasise that the successful management of far laterally located mucoceles and those with laterally situated septation require an external approach in conjunction with endoscopic marsupialisation.<\/jats:p>","DOI":"10.1136\/bcr-2018-226830","type":"journal-article","created":{"date-parts":[[2019,3,21]],"date-time":"2019-03-21T05:14:44Z","timestamp":1553145284000},"page":"e226830","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":4,"title":["Implication of frontal sinus mucocele\u2019s location and intrasinus septation"],"prefix":"10.1136","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8171-7393","authenticated-orcid":false,"given":"K","family":"Devaraja","sequence":"first","affiliation":[{"name":"Otorhinolaryngology and Head and Neck Surgery, Kasturba Medical College, Manipal Academy of Higher Education, Manipal, Udupi, Karnataka, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hitesh","family":"Verma","sequence":"additional","affiliation":[{"name":"Otorhinolaryngology and Head and Neck Surgery, All India Institute of Medical Sciences, New Delhi, Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rajeev","family":"Kumar","sequence":"additional","affiliation":[{"name":"Otorhinolaryngology and Head and Neck Surgery, All India Institute of Medical Sciences, New Delhi, Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2019,3,20]]},"reference":[{"key":"2025082703425733000_12.3.e226830.1","doi-asserted-by":"crossref","first-page":"712","DOI":"10.1002\/alr.21178","article-title":"The natural history and clinical characteristics of paranasal sinus mucoceles: a clinical review","volume":"3","author":"Scangas","year":"2013","journal-title":"Int Forum Allergy Rhinol"},{"key":"2025082703425733000_12.3.e226830.2","doi-asserted-by":"crossref","first-page":"125","DOI":"10.1016\/j.anorl.2011.10.002","article-title":"Sinus mucocele: natural history and long-term recurrence rate","volume":"129","author":"Devars du Mayne","year":"2012","journal-title":"Eur Ann Otorhinolaryngol Head Neck Dis"},{"key":"2025082703425733000_12.3.e226830.3","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-200112000-00009"},{"key":"2025082703425733000_12.3.e226830.4","doi-asserted-by":"crossref","first-page":"106","DOI":"10.4193\/Rhin17.187","article-title":"Mucocele formation after frontal sinus obliteration","volume":"56","author":"Hansen","year":"2018","journal-title":"Rhinology"},{"key":"2025082703425733000_12.3.e226830.5","doi-asserted-by":"crossref","first-page":"1702","DOI":"10.1097\/SCS.0000000000003224","article-title":"Outcomes in surgical treatment of mucocele in frontal sinus","volume":"28","author":"Santos","year":"2017","journal-title":"J Craniofac Surg"},{"key":"2025082703425733000_12.3.e226830.6","doi-asserted-by":"publisher","DOI":"10.1177\/0194599812441570"},{"key":"2025082703425733000_12.3.e226830.7","first-page":"385","article-title":"Mucoceles of the frontal sinus.
