This article presents a case of displaced dental implant into maxillary sinus. Retrieval of the dental implant from left maxillary sinus was performed via endoscopic sinus surgery. This case highlighted a delayed referral of a 53-year-old male by a general dental practitioner for management of a dislodged dental implant into the left maxillary antrum. The implant was dislodged during placement of a healing abutment 4 months after implant insertion to replace missing 25. Cone beam computerized tomography revealed the displaced implant was located at the ostium of the left nose. A sudden change in sinonasal pressure when the patient took a deep breath during the procedure may have created a negative pressure and suction effect causing the implant to be dislodged and embedded at the ostium. In view of its position, a referral to an otorhinolaryngologist was made for endoscopic removal of the displaced implant. This case also highlighted the need for inter disciplinary cooperation in the management of such a complication for the best interest of the patients.<\/jats:p>","DOI":"10.1563\/aaid-joi-d-16-00172","type":"journal-article","created":{"date-parts":[[2016,12,20]],"date-time":"2016-12-20T11:19:23Z","timestamp":1482232763000},"page":"228-231","source":"Crossref","is-referenced-by-count":15,"title":["Transnasal Endoscopy Removal of Dislodged Dental Implant: A Case Report"],"prefix":"10.1563","volume":"43","author":[{"given":"Daniel","family":"Lim","sequence":"first","affiliation":[{"name":"Department of Oro-Maxillofacial Surgical and Medical Sciences, Faculty of Dentistry, University of Malaya, Kuala Lumpur, Malaysia."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rosliza","family":"Parumo","sequence":"additional","affiliation":[{"name":"Oral Surgery Clinic, Hospital Sultanah Aminah, Johor Bahru, Malaysia."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ma Bee","family":"Chai","sequence":"additional","affiliation":[{"name":"Oral Surgery Clinic, Hospital Sultanah Aminah, Johor Bahru, Malaysia."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jothi","family":"Shanmuganathan","sequence":"additional","affiliation":[{"name":"Otorhinolaryngology Clinic, Hospital Sultanah Aminah, Johor Bahru, Malaysia."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"434","reference":[{"key":"i1548-1336-43-3-228-b01","series-title":"J Laryng Otol","first-page":"433","article-title":"Koo Ng NKF, Pulido MA, Saleh HA.
