“…18 It is the most common benign neoplasm of the paranasal sinuses and the orbit, and can present at any age, in most cases, between the 2nd and 5th decades of life. 19 In the craniomaxillofacial region, most of these tumors occur in the mandible instead of the maxilla, causing spontaneous pain, and most are treated with excision of the damaged tissue. 20 They usually present as incidental radiological findings.…”

“…4 En bloc surgical resection has a reported success rate between 88% and 100% but it carries several significant disadvantages. 19 Firstly, for the orthopedic surgeon it may be difficult to identify the precise location of the lesion and the exact amount of bone to resect; secondly, to be sure all the nidus is removed, a substantial volume of bone must be excised, potentially leading to bone weakness and consequent necessity of bone grafts, internal fixation, and postoperative immobilization to prevent subsequent fractures. 18 Nonetheless, recurrence rate remains significantly high (reported in literature to range from 4,5% to 25%) due to incomplete nidus excision.…”

Osteomas are benign slow growing osteogenic tumors mostly arising in the craniofacial region and characterized by the deposition of differentiated and mature either or both cancellous and compact bone. Osteoma accounts for 2-3% of all bone primary tumors with an incidence of 10-12% among all benign skeletal neoplasms. Objective: The objective of this work is to describe a clinical case of an osteoma in the temporomandibular joint diagnosed in the maxillofacial surgery service of the General Hospital of Pachuca in the State of Hidalgo, Mexico. Clinical Case: A 39-year-old female patient who comes to the General Hospital Pachuca, Mexico due to pain and noises in the right preauricular region of 6 years of evolution, with facial asymmetry, mandibular deviation to the left and limited mouth opening. Clinically, facial asymmetry, mandibular deviation to the left, right posterior crossbite, anterior open bite mainly on the affected side, preauricular pain, joint sounds, and limitation of mandibular movements were observed. Radiographic examination revealed a trapezoidal mass measuring 2.5 by 2.0 cm, with alteration of the condyle-mandible anatomy on the right side. An insertional biopsy is performed, reporting an osteoma, and surgical intervention is continued. Conclusion: The osteoma in the temporomandibular joint is a rare lesion, its timely value is essential for its treatment. Surgical resection is the gold standard treatment, which is based on a radical excision that extends to the altered normal bone, with the contextual objective of achieving an optimal aesthetic result by choosing the least invasive surgical treatment possible.

“…Among new surgical tools adapted to the endoscopic surgery and used as an alternative to traditional drills, the piezoelectric scalpel seems the most promising. Piezosurgery acts with an underwater technique that allows selective bone removal preserving soft tissues (4). This device enables a major scutum's removal gaining an adequate exposure of an epitympanic and/or retrotympanic cholesteatoma.…”

Objective Atticotomy represents an essential surgical step within the management of attical cholesteatoma during endoscopic ear surgery. The aim of the present study was to evaluate the safety and functional results of an endoscopic atticotomy performed with piezosurgery, in terms of audiological outcomes and tissue's healing. Methods This is an observational retrospective study on patients with attical cholesteatoma who underwent endoscopic ear surgery with piezoelectric atticotomy and subsequent scutum reconstruction either with tragal cartilage or temporalis muscle fascia. Scutumplasty's status was evaluated via scheduled outpatient controls through an endoscopic check and classified as stable or unstable at least 10 months after surgery. A pre- and postoperative audiometric examination was performed in each patient. Results Eighty-four patients were enrolled. In 50 out of 84 patients (59.52%), an exclusive endoscopic procedure was performed, whereas in 34 patients (40.48%) a combined microscopic/endoscopicapproach was adopted. In 72 cases (85.71%), scutum's reconstruction appeared to be normally positioned, whereas 12 patients developed a retraction pocket, which was self-cleaning in 8 of them and non–self-cleaning in the remaining 4. In 17 patients, a slight sensorineural hearing loss (between 5 and 15 dBHL) was observed, and in 2 patients, the loss was greater than 15 dBHL. Overall, no significative differences between pre- and postoperative pure-tone average bone thresholds resulted (p = 0.4983), though a mild significant hearing deterioration was detected by the specific analysis at 4000 Hz (p = 0.0291). Conclusion Piezosurgery represents an extremely useful tool in performing atticotomy during endoscopic tympanoplasties. Our data seem to support the safety of its usage in this specific step, as it did not lead to any significant sensorineural damage on overall pure-tone average. Moreover, satisfactory tissue healing in regard to scutum reconstruction was observed.
