After a detailed case history, they were subjected to incisional biopsy from an area of buccal mucosa with maximum palpable fibrotic bands.the specimens were cut into two halves, one half was fixed in 10% formalin for routine processing. Second half was fixed in 2.5% glutaraldehyde for electron microscopic examination.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Prospective study of muscle fibres from moderate and advanced stages of osmf0 revealed varying changes in high proportion of muscle fibres which includes, irregularity of surface of fibre,sarcolemmal foldings, reduplicated basement membrane, loss and alterations in the myofilaments, hypercontraction of myofibrils, Z line abnormalities, internal nucleus, autophagic vacuoles. These features are suggestive of muscle atrophy and necrosis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Within the limitations of this study, it can be concluded that the ultra structural features In moderate and advanced stages of osmf0 were best studied. These muscle changes can be manifestation of disease, atrophy being secondary to the limited functional activity of the muscles which is brought about by fibrosis or it could be essential part of the disease process itself.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.4103\/0973-029x.102474","type":"journal-article","created":{"date-parts":[[2012,10,16]],"date-time":"2012-10-16T03:43:20Z","timestamp":1350359000000},"page":"318-324","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":14,"title":["A prospective transmission electron microscopic study of muscle status in oral submucous fibrosis along with retrospective analysis of 80 cases of oral submucous fibrosis"],"prefix":"10.4103","volume":"16","author":[{"given":"MK","family":"Sumathi","sequence":"first","affiliation":[{"name":"Department of Oral and Maxillo Facial Pathology, Indira Gandhi Institute of Dental Science, Pondicherry, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Narayanan","family":"Balaji","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillo Facial Pathology, Indira Gandhi Institute of Dental Science, Pondicherry, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Narasimhan","family":"Malathi","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillo Facial Pathology, Indira Gandhi Institute of Dental Science, Pondicherry, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R1-20250922","doi-asserted-by":"crossref","first-page":"1143","DOI":"10.1177\/000348945706600420","article-title":"Submucous fibrosis of the palate and cheek","volume":"66","author":"Desa","year":"1957","journal-title":"Ann Otol Rhinol Laryngol"},{"key":"R2-20250922","doi-asserted-by":"crossref","first-page":"53","DOI":"10.1002\/path.1700790107","article-title":"Histological, electron microscope and enzyme studies of submucous fibrosis of the palate","volume":"79","author":"Sirsat","year":"1960","journal-title":"J Pathol Bacteriol"},{"key":"R3-20250922","first-page":"150","article-title":"Histopathological observations on cases of submucous fibrosis of the oral cavity","volume":"2","author":"Sharan","year":"1959","journal-title":"Indian J Pathol Microbiol"},{"key":"R4-20250922","first-page":"106","article-title":"Collagenase activity in oral submucous fibrosis","volume":"16","author":"Shieh","year":"1992","journal-title":"Proc Natl Sci Counc Repub China B"},{"key":"R5-20250922","first-page":"474","article-title":"Is SMF a precancerous condition oral cavity?","volume":"22","author":"PindBorg","year":"1972","journal-title":"Ind J Dent"},{"key":"R6-20250922","first-page":"17","article-title":"Oral submucous fibrosis: An unusual disease","volume":"68","author":"Aziz","year":"1997","journal-title":"J N J Dent Assoc"},{"key":"R7-20250922","first-page":"70","article-title":"Studies on oral submucous fibrosis.
