Middle Ear and Temporal Bone Papilloma: A Clinicopathologic Study and Comprehensive Literature Review of 57 Cases.

Head Neck Pathol 2021 May 21. Epub 2021 May 21.

Department of Pathology, Southern California Permanente Medical Group, 5601 De Soto Avenue, Woodland Hills, CA, 91365, USA.

Sinonasal papilloma (SP), formerly Schneiderian papilloma, represents a rare group of benign epithelial neoplasms, most commonly identified in the sinonasal tract, while less frequently identified in the pharynx, lacrimal sac, and middle ear. Within temporal bone sinonasal-type papilloma (TBSP), there seems to be a much higher recurrence and malignant transformation risk than those identified in the sinonasal tract. Based on this clinical report and a review of the cases reported in the English literature, 49% of the 57 cases developed in the setting of concurrent or antecedent sinonasal or nasopharyngeal SP.

Institute of Otolaryngology, Chinese PLA General Hospital, Beijing 100853, China National Clinical Research Center for Otolaryngologic Diseases, Beijing 100853, China.

To discuss the techniques and repairing methods of various degree of compound tissue defects in the auriculotemporal region. Retrospective analysis was conducted on three cases of different repairing methods for huge compound tissue defects in different degrees in the auriculotemporal region after the resection of the malignant tumor or sinus tract due to repeated infection in our hospital. Following total removal of the tumors or sinus tract in all patients, we applied retroauricular lingual flap transfer repairing, latissimus dorsi flap free transfer repairing and vascular anastomosis, scalp tissue expansion in stage Ⅰ, then repairing the lesion with expanded scalp and filling the huge mastoid cavity with abdominal fat in stage Ⅱ, respectively, according to the characteristics of compound tissue defects in the auriculotemporal region.

The evolution of bone marrow signal changes at the skull base in nasopharyngeal carcinoma patients treated with radiation therapy.

Radiol Med 2021 Jun 31;126(6):818-826. Epub 2021 Mar 31.

Department of Radiology, University of Illinois at Chicago, Chicago, IL, USA.

Background: Clival infiltration is frequently seen in nasopharyngeal carcinoma (NPC) and the resultant bone marrow signal changes (BMSC) can persist even after complete tumor response to the radiation therapy (RT). The differentiation of those residual BMSC from recurrent/persistent disease may be challenging. We performed serial analysis of the clival BMSC after RT, to define an expected temporal evolution of those signal changes during the follow-up. Read More

Vascularized Composite Parietal Bone Flap for Immediate Reconstruction of a Hemi-Maxillectomy Defect in an Infant.

J Craniofac Surg 2020 Nov/Dec;31(8):2334-2338

Division of Plastic and Reconstructive Surgery, Department of Surgery, Yale School of Medicine, New Haven, CT.

Background: Surgical resection of maxillary tumors can result in defects that can be difficult to reconstruct by conventional means due to the complex functional and anatomic nature of the midface and lack of regional bone flap options in the head and neck. Many reconstructive methods have been used to repair maxillary defects, but the ideal technique for the reconstruction of hemi-maxillectomy defects in growing pediatric patients has yet to be determined.

Methods: The authors present a rare pediatric patient with melanotic neuroectodermal tumor of infancy resulting in a hemi-maxillectomy defect after resection that was reconstructed using a pedicled vascularized composite flap consisting of temporalis muscle, pericranium, and parietal bone.
