Aim This systematic review aimed to investigates the types and incidences of complications following sinus floor elevations (SFE) along with their prevention and management strategies. Materials and methods Electronic database and hand search were conducted to screen the literature published from January 1960 to June 2021. The selected studies had to report well‐described SFE techniques, complications during, and post‐SFE. Data extraction included types of SFE techniques, complications, and their treatment strategies. Results A total of 74 studies with 4411 SFE procedures met the inclusion criteria. Different SFE techniques demonstrated varying patterns for both complications and complication rates. Postoperative pain, swelling, and edema were widely reported. The most common complications that required intervention following Lateral SFE (LSFE) were sinus membrane perforation (SMP), wound dehiscence, graft exposure and failure, and sinusitis. LSFE had more SMPs and sinusitis cases compared with a transcrestal SFE (TSFE). The presence of benign paroxysmal positional vertigo following TSFE was significant in certain selected studies. Conclusion Given the inherent limitations, this systematic review showed distinct features of complications in SFE using varying techniques. Treatment planning for these procedures should incorporate strategies to avoid complication occurrence.

Introduction:Many mucocutaneous conditions affect the skin and oral cavity. Common conditions include lichen planus, pemphigus, and pemphigoid. This case report shows an atypical presentation of a mucocutaneous condition wherein histopathology was required for definitive diagnosis and treatment. Case Presentation:A 51-year-old African American male self-reported to a private periodontal practice with a chief complaint of sporadic painful oral lesions of about 2 months duration. The patient also reported painful throat lesions. He had been previously treated for a sore throat followed by unspecified inflammation of the epiglottis. Clinical examination revealed diffuse bilateral eye redness, numerous intraoral ulcerations on soft and hard palate and floor of the mouth with trouble swallowing. Oral and ocular presentation suggested a differential diagnosis of cicatricial pemphigoid. Pemphigoid and lichen planus were also considered. Ophthalmologic exam revealed only allergies and no other abnormality. Soft tissue biopsies showed intraepithelial separation between the spinous layer and basement membrane. Direct and indirect immunofluorescence showed strong immunoglobulin G and moderate C3 reactivity confirming a diagnosis of pemphigus vulgaris (PV). A rheumatologist initially treated the patient with a daily combination regimen of methylprednisolone and mycophenolate mofetil. Lesions improved after a few weeks on the regimen. Reduction of medications resulted in return of oral and throat lesions. Resumption of the regimen resulted in lesion remission. Azathioprine replaced the mycophenolate mofetil, and then was gradually stopped after methylprednisolone cessation. Lesions have not reappeared for 1 year. Conclusion:This case illustrates that early diagnosis of mucocutaneous lesions leads to proper treatment and possible remission. Clin Adv Periodontics 2018;8:145-150.
