The problem with RMSO craniotomy is the risk of injury to the transverse and sigmoid sinus during the fashioning of the craniotomy. This problem creates a craniectomy defect that is larger than the bone flap removed. Placement of such a bone flap would cause problems that are similar to the craniectomy defects. To avoid this complication, cranioplasty reconstruction is advised.<\/jats:p>\n                  <jats:p>In this study, we introduced a novel, low-cost technique for RMSO cranioplasty using a single standard polyvinyl chloride plastic skull model as a guide for cranioplasty flap development and observed the functional and cosmetic outcomes.<\/jats:p>\n                  <jats:p>None of the patients required reoperation, and there was no evidence of cerebrospinal fluid (CSF) leak, bleeding, infection, or poor scar formation. No patient experienced undue incisional pain or headache at long-term follow-up. The patients and their family members were satisfied with the cosmetic results of the procedure.<\/jats:p>\n                  <jats:p>This technique has been proven to be not only cost-effective but also time-saving and easily reproduced, which may be significantly relevant in countries such as India, where the financial burden of healthcare is very high. This study identifies long-term improvement in CSF leaks and the long-term advantage of polymethylmethacrylate closure with less postoperative incisional pain and headache and improvement retroauricular cosmesis.<\/jats:p>","DOI":"10.1055\/s-0045-1809920","type":"journal-article","created":{"date-parts":[[2025,6,26]],"date-time":"2025-06-26T18:56:44Z","timestamp":1750964204000},"page":"769-774","source":"Crossref","is-referenced-by-count":0,"title":["Utility of PMMA-Based Cranioplasty Flap for the Reconstruction of Retromastoid Craniotomy Using a Single Standard Skull Model: A Low-Cost Alternative"],"prefix":"10.1055","volume":"20","author":[{"given":"Mohammad","family":"Kaif","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Dr. Ram Manohar Lohia Institute of Medical Sciences, Lucknow, Uttar Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Deepak Kumar","family":"Singh","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Dr. Ram Manohar Lohia Institute of Medical Sciences, Lucknow, Uttar Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Diwakar","family":"Shankar","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Dr. Ram Manohar Lohia Institute of Medical Sciences, Lucknow, Uttar Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rakesh Kumar","family":"Singh","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Dr. Ram Manohar Lohia Institute of Medical Sciences, Lucknow, Uttar Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kuldeep","family":"Yadav","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Dr. Ram Manohar Lohia Institute of Medical Sciences, Lucknow, Uttar Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2025,6,26]]},"reference":[{"key":"ref1","first-page":"405","volume-title":"The Same Points in the Surgery of the Brain and Its Membranes","author":"C A Ballanre","year":"1907"},{"key":"ref2","first-page":"24","volume-title":"Surgery of the Brain and Spinal Cord","author":"F Krause","year":"1911"},{"key":"ref3","first-page":"295","volume-title":"Tumors of the Nervus Acousticus and the Syndrome of the Cerebello-pontine Angle","author":"H Cushing","year":"1917"},{"key":"ref4","doi-asserted-by":"crossref","first-page":"1026","DOI":"10.1001\/archsurg.1941.01210120061006","article-title":"Results of removal of acoustic tumours by the unilateral approach","volume":"42","author":"W E Dandy","year":"1941","journal-title":"Arch Surg"},{"issue":"72","key":"ref5","doi-asserted-by":"crossref","first-page":"7","DOI":"10.1097\/00003086-197009000-00003","article-title":"Total hip replacement by low-friction arthroplasty","volume":"72","author":"J Charnley","year":"1970","journal-title":"Clin Orthop Relat Res"},{"key":"ref6","doi-asserted-by":"crossref","first-page":"105755","DOI":"10.1016\/j.ijscr.2021.105755","article-title":"\u201cSingle-step\u201d resection and cranio-orbital reconstruction for spheno-orbital metastasis with custom made implant.
