Mucocele was unilateral in 26 (92.9%) patients. Twenty patients (71.43%) presented with primary mucocele. The distribution of mucocele was frontal and frontoethmoidal in 8 (28.6%) patients each, maxillary in 6 (21.4%), and ethmoid and sphenoid sinus in 3 (10.7%) patients each. Sixteen (57.1%) patients had frontal sinus involvement. At presentation, 13 (46.4%) patients had nasal symptoms, 17 (60.7%) had orbital symptoms, while 16 (57.1%) had headache. Pain (12; 70.59%) was the predominant orbital symptom, followed by proptosis and diplopia (8; 47.06%). The most common sites of bony erosions were along the frontal sinus floor (14; 50%), followed by lamina papyracea (13; 46.43%), and frontal sinus anterior wall (10; 35.71%). The agger nasi and suprabullar cells were the most common frontal cells encountered in mucoceles involving the frontal sinus, with no significant difference in frontal cell distribution between involved and uninvolved sides. The frontal cell distribution was similar in mucoceles with and without frontal sinus involvement too.<\/jats:p><jats:p>\n          Conclusion\u2003Though frontal and frontoethmoidal mucoceles were the most encountered, the type and distribution of frontal cells did not predispose to mucocele formation.<\/jats:p>","DOI":"10.1055\/s-0044-1788002","type":"journal-article","created":{"date-parts":[[2025,1,22]],"date-time":"2025-01-22T23:57:14Z","timestamp":1737590234000},"page":"001-006","source":"Crossref","is-referenced-by-count":0,"title":["Do Variations in Frontal Recess Anatomy Predispose to Mucocele Formation?"],"prefix":"10.1055","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9281-7071","authenticated-orcid":false,"given":"Lalee","family":"Varghese","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Christian Medical College, Vellore, Tamil Nadu, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rakesh R.","family":"Bright","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Christian Medical College, Vellore, Tamil Nadu, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aditya V.
