2014年5月1日 · The frontal sinus drillout procedure is a viable alternative for endoscopic management prior to frontal obliteration for frontal sinusitis that persists despite initial sinusotomy. It offers the advantages of decreased morbidity, improved cosmesis, and an enhanced ability to survey for recurrent disease.

Removal of the floor of the frontal sinus with a drill is reserved for patients with severe frontal sinusitis in whom previous surgery has failed and those with frontal sinus mucoceles. The 80% success rate obtained in this study demonstrates the efficacy of frontal sinus drillout for the treatment of severe frontal sinus disease.

A crestal approach for implant placement in deficient alveolar ridges is presented. The set of drills allows the surgeon to lift the membrane at the floor of the maxillary sinus with a bone disc, without the risk of tearing it. The plastic and cutting drills, respectively, are set in just below the …

The modified Lothrop procedure or frontal sinus drill-out is a completely intranasal technique that creates a common frontonasal communication to allow drainage and ventilation of the chronically infected frontal sinus. It is an effective alternative to the classic frontal sinus obliteration.

Frontal sinus drillout performed with or without an image-guidance system appears to be a safe and effective surgery for the treatment of patients with advanced disease of the frontal sinus. This procedure provides a reasonable alternative to frontal sinus obliteration, which remains a treatment opt …

2 天之前 · The classification numbering is based on the sequential opening of the sphenoid sinus, where stage 1 is to approach the sinus without widening the ostium, stage 2 is widening the ostium in different degrees A–C but without connecting both sides together and stage 3 is when we connect both sides of the sinuses together in different degrees.
