A Retrospective Study of Clinical and Radiologic Outcomes of 69 Consecutive Maxillary Sinus Augmentations Associated with Functional Endoscopic Sinus Surgery

Abstract

Preliminary rhinosinusal evaluation by an ENT specialist and computed tomography of the ostiomeatal complex are necessary in patients needing maxillary sinus elevation. A single-step approach to FESS and sinus elevation is a predictable technique to manage patients with ENT reversible contraindications to sinus elevation.

The Use of Cone‐Beam Computed Tomography in Management of Patients Requiring Dental Implants: An American Academy of Periodontology Best Evidence Review

“…Such cases can lead to postoperative complications such as infection and insufficient bone formation if sinus augmentation is performed. CBCT could potentially be used to ensure the ostiomeatal complex (or unit) is healthy prior to performing sinus bone graft surgery 130 . CBCT evaluations showing sinusitis issues or pathology may be considered for referral to a otolaryngologist for further clinical and radiographic evaluation.…”

“…The literature is scant regarding CBCT application for diagnosis of any pathology in the ostiomeatal complex. A study among patients suffering from reversible contraindications to sinus elevation reports on this use 130 . Otherwise, such studies seem to mostly concern dental implants accidentally displaced to the ostiomeatal complex region 132,133 and cases in which the Schneiderian membrane is damaged or infected by sinus augmentation in preparation for implant placement 131 …”

“…CBCT could potentially be used to ensure the ostiomeatal complex (or unit) is healthy prior to performing sinus bone graft surgery. 130 CBCT evaluations showing sinusitis issues or pathology may be considered for referral to a otolaryngologist for further clinical and radiographic evaluation. However, such imaging is not currently recommended for general use, although it might be used in patients with chronic sinusitis.…”

Anatomic variations of the osteomeatal complex and its relationship to patency of the maxillary ostium: A retrospective evaluation of cone-beam computed tomography and its implications for sinus augmentation

“…[ 6 ] The presence of anatomic variants can cause an obliterated OMC. [ 12 ] The incidence of anatomic variants of the OMC is quite high. [ 13 14 15 ] Earwaker reported 93% of cases presenting with one or more than one variant, while only 41% were considered “endoscopically normal.”[ 16 ] Preoperative detection of such variations can help in avoiding postsurgical complications.…”

Case Report: The Clinical Application of a Surgical Navigation System for Implant-Prosthetic Rehabilitation of the Patient with Maxillary Lateral Incisors Agenesis

“…In oral surgery, likewise, the tendency is observed to decrease the number of surgeries with simultaneous increase in their precision [3]. It is realized by progressively wider application of microsurgical techniques, systems magnifying a microscopic image (micro-lenses, magnifiers), endoscopic techniques (sinusoscopy, arthroscopy, sialoendoscopy) and, recently introduced, surgical navigation (surgical templates, surgical robots) allowing for much more minimally invasive surgeries [4]. Surgical navigation has become applicable in dental implantology where because of restricted operative field, and numerous adjacent structures (teeth and their buds, the nasal cavity, maxillary sinuses, the mandibular canal, mental foramina, the nasopalatinal canal), the precision of surgical procedures is of special importance.…”
