bookPart Lindofonodos cervicais(2017) GOMES, Regina Lúcia Elia; SARPI, Maíra de Oliveira- Adverse Radiation Therapy Effects in the Treatment of Head and Neck Tumors(2022) ROCHA, Pedro H. P.; REALI, Raphael M.; DECNOP, Marcos; SOUZA, Soraia A.; TEIXEIRA, Lorine A. B.; LUCAS JUNIOR, Ademar; SARPI, Maira O.; CINTRA, Murilo B.; PINHO, Marco C.; GARCIA, Marcio R. T.Whether used as a single modality or as part of a combined approach, radiation therapy (RT) plays an essential role in the treatment of several head and neck malignancies. Despite the improvement in radiation delivery techniques, normal structures in the vicinity of the target area remain susceptible to a wide range of adverse effects. Given their high incidence, some of these effects are referred to as expected postradiation changes (eg, mucositis, sialadenitis, and edema), while others are considered true complications, meaning they should not be expected and can even represent lifethreatening conditions (eg, radionecrosis, fistulas, and radiationinduced neoplasms). Also, according to their timing of onset, these deleterious effects can be divided into four groups: acute (during RT), subacute (within weeks to months), delayed onset (within months to years), and very delayed onset (after several years).The authors provide a comprehensive review of the most important radiation-induced changes related to distinct head and neck sites, focusing on their typical cross-sectional imaging features and correlating them with the time elapsed after treatment. Radiologists should not only be familiar with these imaging findings but also actively seek essential clinical data at the time of interpretation (including knowledge of the RT dose and time, target site, and manifesting symptoms) to better recognize imaging findings, avoid pitfalls and help guide appropriate management.

V. C.; PADULA, Mario; SARPI, Maira O.; GOMES, Regina L. E.; TOYAMA, Carlos; MURAKOSHI, Rodrigo W.; OLIVETTI, Bruno C.; GEBRIM, Eloisa M. M. S.The anatomy of the temporal bone is complex, and postoperative imaging evaluation of this bone can be challenging. Surgical approaches to the temporal bone can be categorized didactically into tympanoplasty and ossicular reconstruction, mastoidectomy, and approaches to the cerebellopontine angle and internal auditory canal (IAC). In clinical practice, different approaches can be combined for greater surgical exposure. Postoperative imaging may be required for follow-up of neoplastic lesions and to evaluate unexpected outcomes or complications of surgery. CT is the preferred modality for assessing the continuity of the reconstructed conductive mechanism, from the tympanic membrane to the oval window, with use of grafts or prostheses. It is also used to evaluate aeration of the tympanic and mastoid surgical cavities, as well as the integrity of the labyrinth, ossicular chain, and tegmen. MRI is excellent for evaluation of soft tissue. Use of a contrast-enhanced fat-suppressed MRI sequence is optimal for follow-up after IAC procedures. Non-echo-planar diffusion-weighted imaging is optimal for detection of residual or recurrent cholesteatoma.The expected imaging findings and complications of the most commonly performed surgeries involving the temporal bone are summarized in this review.
