Closed Atraumatic Rhinoplasty
Published in Suleyman Tas, Rhinoplasty in Practice, 2022
Bone structures are the main support element of the nose; this support is weakened when osteotomy is performed. Therefore, it is very important to know the concept of osteoplasty. In the first step, reshaping of the nasal and maxillary bones will be a more conservative approach with osteoplasty techniques. If osteoplasty is not enough, then osteotomy can proceed to get the desired shape. When and how should osteoplasty be performed?

A fracture in the bone undergoes several stages of healing after the fragments of the broken bone are manipulated or reduced back to their original position. The bone is usually then immobilized by a splint, cast, or traction. Follow-up surgery and/or physical therapy are sometimes necessary. Procedural terms relating to treatment of bones include manipulation, skeletal traction, percutaneous skeletal fixation, bone grafts, amputation, and osteoplasty. Photon absorptiometry and bone scans are diagnostic procedures.

With regard to the extent and type of capsulotomy, the least amount of capsular disruption is advised. If possible, it is important to try to avoid excessively medializing the interportal capsulotomy beyond 2 o'clock to limit the exposure of the iliopsoas. Although the capsulotomy has to be large enough to adequately perform femoral osteoplasty, pincer and labral work, as previously noted, the smaller the capsulotomy, the less repair is required.1

Furthermore, the combination of MWA and PVP has a synergistic anti-tumor and analgesic effect [19]. In this study, the average VAS score of the 23 patients significantly decreased from 6.7 pre-operatively to 1.0 post-operatively. However, it is important to note that cases with an incomplete posterior vertebral body edge are contraindicated for PVP. Hoffmann et al. reported that ablation before osteoplasty could destroy tumor tissue; therefore, ablation increases the safety of osteoplasty because it obliterates tumor vessels and changes the consistency of the tumor, allowing bone cement to be more easily distributed within the lesion [20]. Hence, ablation combined with vertebroplasty can be used to treat vertebral metastases. This combination also converts the contraindications of PVP into indications, which greatly expands the scope of application. Schaefer et al. reported that coagulation necrosis can be produced by RF heat ablation, leading to homogenous distribution of the polymethylmethacrylate in the lesion [21]. In this study, a total of 11 patients with the destruction of the posterior edge of the vertebral body were able to receive safe injections of bone cement for vertebral reconstruction, further demonstrating the advantage of combining MWA with PVP.

In the consecutive group of 236 cases, CWU was the intention. In six of these, the ear canal had to be removed due to an unfavorable anatomy. In four cases, the en bloc osteoplasty, as described by Mercke, was used. In a further two ears, a CWD operation was necessary. Meeting the inclusion criteria of the study, 230 ear operations in 224 patients were further analyzed. The characteristics of the study group are presented in Table 3. Two hundred (87%) of the procedures were performed by three senior and 30 (13%) mainly by two junior surgeons supervised by senior colleagues. The mean operating time was five hours (SD 1.3). The ossicular chain was preserved in 19 (8%) ears. A PORP was used for reconstruction in 148 (64%) and a TORP in 60 (26%) ears. In all operations autologous bone, ossicular or cortical, was used. In 10 ears, a labyrinthine fistula was encountered. Five of which were reconstructed with a PORP and five with a TORP. Two hundred and twenty-six ears (98%) were followed up one-year postoperatively. The three-year status was obtained in 200 (87%) cases. A normalized anatomy with an intact ear drum was obtained in 90% of the cases. Three (1%) residual cholesteatomas have been detected until April 2016. There were eighteen (8%) recurrent cholesteatomas as presented in Table 2. In total, 56 (24%) revisions were done, as shown in Table 2. Most revisions were performed due to a malfunctioning ossiculoplasty.

Cam regrowth was evaluated based on postoperative plain radiographs with the cross-table lateral view and modified Dunn view. To evaluate the alpha angle precisely, we utilized the same view of radiographs and postoperative radiographs. An alpha angle bigger than that measured by radiographs just after surgery was defined as cam regrowth (Figure 3). Patients were evaluated immediately postoperatively, and postoperatively at 6 months, 1 year, and 2 years. The decision to perform revision arthroscopy was based on the patient’s symptom, image evaluation findings including cam regrowth, residual AIIS impingement, and labral re-tear, and physical examination findings. If cam regrowth was found on radiographs images, we performed secondary cam osteoplasty for revision arthroscopy.
