Inclusion criteria for study were: (1) cases with focal meato-mastoid fistulae and (2) focal meato-mastoid fistulae that were repaired by using bony sigmoid sinus plate using the bony sigmoid sinus plate technique. There were 13 cases that fulfilled these criteria.<\/jats:p><\/jats:sec><jats:sec id=\"S0022215121004473_sec_a3\" sec-type=\"results\"><jats:title>Results<\/jats:title><jats:p>The outcome of the repair of meato-mastoid fistulae with bony sigmoid sinus plate was very encouraging.

Bony sigmoid sinus plate is easily and locally available in all cases undergoing cortical mastoidectomy. This plate of bone has a curvature, consistency and structure that match well with that of the posterior or superior canal wall. In addition, this technique is cost-effective with good patient compliance.<\/jats:p><\/jats:sec>","DOI":"10.1017\/s0022215121004473","type":"journal-article","created":{"date-parts":[[2022,1,11]],"date-time":"2022-01-11T12:08:51Z","timestamp":1641902931000},"page":"151-157","source":"Crossref","is-referenced-by-count":1,"title":["Focal meato-mastoid fistula closure using bony sigmoid sinus plate"],"prefix":"10.1017","volume":"137","author":[{"given":"S","family":"Indorewala","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8251-4467","authenticated-orcid":false,"given":"K","family":"Parelkar","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A","family":"Indorewala","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G","family":"Mahajan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D","family":"Shere","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2022,1,11]]},"reference":[{"key":"S0022215121004473_ref7","doi-asserted-by":"crossref","first-page":"577","DOI":"10.1111\/j.1365-2273.2004.00898.x","article-title":"Keratosis obturans and external ear canal cholesteatoma","volume":"29","author":"Persaud","year":"2004","journal-title":"Clin Otolaryngol"},{"key":"S0022215121004473_ref11","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1002\/lary.27218","article-title":"Evaluation and treatment of pulsatile tinnitus associated with sigmoid sinus wall anomalies","volume":"128","author":"Eisenman","year":"2018","journal-title":"Laryngoscope"},{"key":"S0022215121004473_ref1","doi-asserted-by":"crossref","first-page":"31","DOI":"10.1097\/MAO.0000000000000182","article-title":"Vascularized reconstruction of partial external auditory canal wall defects using the middle temporal artery flap","volume":"35","author":"Gluth","year":"2014","journal-title":"Otol Neurotol"},{"key":"S0022215121004473_ref4","doi-asserted-by":"crossref","first-page":"88","DOI":"10.1016\/j.otorri.2019.03.003","article-title":"Butterfly tragal cartilage for repair of focal canal wall defects","volume":"71","author":"Parelkar","year":"2020","journal-title":"Acta Otorrinolaringol Esp"},{"key":"S0022215121004473_ref2","doi-asserted-by":"crossref","first-page":"832","DOI":"10.1017\/S0022215106001927","article-title":"Posterior canal wall reconstruction with a composite cartilage titanium mesh graft in canal wall down tympanoplasty and revision surgery for radical cavities","volume":"120","author":"Sudhoff","year":"2006","journal-title":"J Laryngol Otol"},{"key":"S0022215121004473_ref9","doi-asserted-by":"crossref","first-page":"115","DOI":"10.1055\/s-2004-828707","article-title":"Facial nerve neuroma: clinical, diagnostic, and surgical features","volume":"14","author":"Kirazli","year":"2004","journal-title":"Skull Base"},{"key":"S0022215121004473_ref8","doi-asserted-by":"crossref","first-page":"1170","DOI":"10.1288\/00005537-197407000-00011","article-title":"Neuroma of the chorda tympani nerve","volume":"84","author":"Pou","year":"1974","journal-title":"Laryngoscope"},{"key":"S0022215121004473_ref10","doi-asserted-by":"crossref","first-page":"279","DOI":"10.1258\/0022215001905553","article-title":"Defects of the external auditory canal: a new reconstruction technique","volume":"114","author":"Anand","year":"2000","journal-title":"J Laryngol Otol"},{"key":"S0022215121004473_ref5","doi-asserted-by":"crossref","first-page":"227","DOI":"10.1177\/019459988509300219","article-title":"Tympanomastoid surgery: a technique for repairing posterior osseous canal wall defects with autologous temporalis fascia and bone pate","volume":"93","author":"Althaus","year":"1985","journal-title":"Otolaryngol Head Neck Surg"},{"key":"S0022215121004473_ref6","doi-asserted-by":"crossref","first-page":"66","DOI":"10.4303\/jcrm\/235736","article-title":"Precise reconstruction of auditory canal defect in external auditory canal cholestestoma with bonewax template","volume":"1","author":"Cho","year":"2013","journal-title":"J Case Rep Med"},{"key":"S0022215121004473_ref3","doi-asserted-by":"crossref","first-page":"6","DOI":"10.1177\/00034894860950S202","article-title":"Reconstruction of the posterior auditory canal wall with a hydroxyapatite prosthesis","volume":"95","author":"Grote","year":"1986","journal-title":"Ann Otol Rhinol Laryngol"}],"container-title":["The Journal of Laryngology &amp;
