RESUMEN
Frontal sinus trephination (FST) has numerous applications in the treatment of acute and chronic sinus disease. This procedure involves making an incision at the medial aspect of the supraorbital rim and then drilling the sinus's anterior table. Placement of a frontal trephine allows for irrigation of the frontal recess in order to evacuate the frontal sinus in a minimally invasive manner. Orbital injury is a rare complication of FST. We present a case of previously unreported orbital compartment syndrome secondary to iatrogenic fracture of the superomedial orbital rim as a complication of frontal trephine irrigation. We also review the literature on the applications of FST and its associated complications, and we discuss orbital compartment syndrome as a complication of sinus surgery.

OBJECTIVES/HYPOTHESIS: To evaluate the feasibility and efficacy of transtympanic L-N-Acetylcysteine (L-NAC) administration in patients receiving cisplatin chemotherapy for head and neck cancer. STUDY DESIGN: Prospective randomized nonblinded open-label clinical trial. METHODS: Transtympanic 2% L-NAC was administered to one randomly selected ear with the other ear as control in each patient. Primary outcome parameter was the difference in the loss of pure tone averages (PTA) at 2, 4, and 8 kHz between the L-NAC and control ear at 1 to 2 months following chemotherapy. RESULTS: Eleven patients completed the study, with two patients demonstrating significantly better hearing in the L-NAC treated ear (18.2%). However, for the overall group, the difference in hearing preservation did not reach significance. Two percent L-NAC administration was well tolerated in this patient population. There were no adverse effects associated with L-NAC. CONCLUSION: Although the study did not demonstrate a significant benefit overall, transtympanic L-NAC was associated with significantly better hearing in two patients. Better delivery methods may improve the efficacy of this treatment. L-NAC remains a promising drug in preventing cisplatin-induced ototoxicity.
