ReviewHereditary hemorrhagic telangiectasia-related epistaxis: innovations in understanding and management.
Epistaxis is the most common manifestation of hereditary hemorrhagic telangiectasia (HHT), affecting approximately 90% of patients at some point during their lifetime. Bleeding is chronic and varies from mild, self-limited episodes to severe, transfusion-dependent or life-threatening epistaxis. Treatment options vary from conservative, nonsurgical management to more aggressive surgical approaches. A number of treatment options have been introduced in recent years. There is little consensus in the literature regarding treatment algorithms. The objective of this investigation was to provide a contemporary review of HHT-related epistaxis, including pathophysiology, disease manifestations, and state-of-the-art treatment modalities. ⋯ HHT is a heterogeneous disease requiring multidisciplinary evaluation and treatment. Therapeutic options for HHT-related epistaxis vary from conservative, nonsurgical measures to more aggressive surgical treatments. A graduated treatment plan is recommended. Patients present with a wide degree in variation of severity of epistaxis, and treatment is best tailored to the individual patient.

Efficacy of the pedicled nasoseptal flap without cerebrospinal fluid (CSF) diversion for repair of skull base defects: incidence of postoperative CSF leaks.
The advances in endoscopic skull base surgery have led to the resection of increasingly larger cranial base lesions and the creation of larger skull base defects with the potential for increased postoperative high-flow cerebrospinal fluid (CSF) leaks. These concerns led to the development of the vascularized pedicled nasoseptal flap (PNSF), which is now used as the mainstay for repair of large skull base defects in many academic centers. In this report, we review the incidence of postoperative CSF leaks in our institution in patients undergoing endoscopic skull base repair of high-flow CSF leaks with a vascularized PNSF without concurrent CSF diversion. ⋯ Meticulous multilayer-closure of skull base defects is critical to prevent postoperative CSF leaks. Although lumbar drainage may be useful in select scenarios, it carries inherent risks of intracranial hypotension and pneumocephalus, and may not be necessary for routine management of high-flow CSF leaks in conjunction with a robust PNSF. Further prospective randomized controlled studies may be warranted to evaluate the efficacy of postoperative lumbar drainage.

Corticosteroid nasal irrigations after endoscopic sinus surgery in the management of chronic rhinosinusitis.
Inflammatory dysfunction is considered an important part of chronic rhinosinusitis (CRS). Corticosteroid therapy has been widely used in CRS. Effective topical delivery has been previously problematic. The post-endoscopic sinus surgery (ESS) corridor is essential for adequate topical drug access. Devices delivering large volume with positive pressure allow better distribution to sinus mucosa. The objective of this study is to evaluate the efficacy of postoperative topical sinonasal steroid irrigations for CRS. ⋯ The philosophical approach to ESS in CRS is evolving. Topical therapies, when used appropriately, are highly effective for the most challenging eosinophilic patients. Although corticosteroid is a nonspecific therapy, it is effective when appropriately delivered.
