Endoscopic surgery in the treatment of crista galli pneumatization evolving with localizated frontal headaches.

ABSTRACT: INTRODUCTION: The crista galli is part of the ethmoid bone and thus may suffer from the process of pneumatization. Pneumatization occurs in between 3% and 14% of patients, resulting from air cells in the frontal or ethmoid sinuses. AIM: To describe 3 cases of crista galli pneumatization in which the patients developed infection and were treated surgically by endoscopic techniques. METHOD: We present 3 case studies of patients complaining of severe frontal headaches. The patients underwent ENT evaluation, examination by video-endoscopy, and computed tomography, which identified crista galli pneumatization with mucosal thickening and the presence of fluid. Patients underwent treatment with antibiotics and corticosteroids; however, they showed no symptomatic improvement, displayed recurrence of symptoms, and maintained radiographic changes. Thus, patients then underwent drainage through the crista galli via an endoscopic procedure. DISCUSSION: During surgery, mucopurulence and/or mucosal thickening and edema were identified in the pneumatized crista galli. There were no complications during or after surgery. Postoperatively, headache was improved in patients after a minimum follow-up of 6 months. CONCLUSION: Crista galli pneumatization can result in infection, simulating rhinosinusitis. When there is little response to drug therapy, endoscopic surgical treatment is required; the current cases demonstrate that this technique is safe and effective.

Project description:Importance:Endoscopic surgical decompression of the supratrochlear nerve (STN) and supraorbital nerve (SON) is a new treatment for patients with frontal chronic headache who are refractory to standard treatment options. Objective:To evaluate and compare treatment outcomes of oral medication, botulinum toxin type A (BoNT/A) injections, and endoscopic decompression surgery in frontal secondary headache attributed to STN and supraorbital SON entrapment. Design, Setting, and Participants:Prospective cohort study of 22 patients from a single institution (Diakonessen Hospital Utrecht) with frontal headache of moderate-to-severe intensity (visual analog scale [VAS] score, 7-10), frontally located, experienced more than 15 days per month, and described as pressure or tension that intensifies with pressure on the area of STN and SON. A screening algorithm was used that included examination, questionnaire, computed tomography of the sinus, injections of local anesthetic, and BoNT/A in the corrugator muscle. Interventions:Different oral medication therapy for headache encountered in the study cohort, as well as BoNT/A injections (15 IU) into the corrugator muscle. Surgical procedures were performed by a single surgeon using an endoscopic surgical approach to release the supraorbital ridge periosteum and to bluntly dissect the glabellar muscle group. Main Outcomes and Measures:Headache VAS intensity after oral medication and BoNT/A injections. Additionally, early postoperative follow-up consisted of a daily headache questionnaire that was evaluated after 1 year. Results:In total, 22 patients (mean [SD] age, 42.0 [15.3] years; 7 men and 15 women) were included in this cohort study. Oral medication therapy reduced the headache intensity significantly (mean [standard error of the mean {SEM}] VAS score, 6.45 [0.20] [95% CI, 0.34-3.02; P?<?.001] compared with mean [SEM] pretreatment VAS score, 8.13 [0.22]). Botulinum toxin type A decreased the mean (SEM) headache intensity VAS scores significantly as well (pretreatment, 8.1 [0.22] vs posttreatment, 2.9 [0.42]; 95% CI, 3.89-6.56; P?<?.001). The mean (SEM) pretreatment headache intensity VAS score (8.10 [0.22]) decreased significantly after surgery at 3 months (1.30 [0.55]; 95% CI, 5.48-8.16; P?<?.001) and 12 months (1.09 [0.50]; 95% CI, 5.71-8.38; P?<?.001). There was a significant decrease of headache intensity VAS score in the surgical group over the BoNT/A group (mean [SEM] VAS score, 2.90 [0.42]) after 3 months (mean [SEM] VAS score, 1.30 [0.55]; 95% CI, 0.25-2.93; P?<?.001) and 12 months (mean [SEM] VAS score, 1.09 [0.50]; 95% CI, 0.48-3.16; P?<?.001) after surgery. Conclusions and Relevance:Endoscopic decompression surgery had a long-lasting successful outcome in this type of frontal secondary headache. Even though BoNT/A had a positive effect, the effect of surgery was significantly higher. Level of Evidence:3.

Project description:PurposeWe report a case of old submacular hemorrhage (SMH) due to polypoidal choroidal vasculopathy (PCV). Subretinal endoscopic surgery (SES) was performed, which improved visual function. In addition, we show the intraoperative findings of subretinal aberrant PCV vessels as seen under endoscopic observation, which cannot be observed by microscopic surgery.ObservationsA 71-year-old Japanese man presented with an old dehemoglobinized SMH due to PCV in his left eye. At the time of presentation, three weeks had already passed after the onset of the patient's symptoms, and the best-corrected visual acuity (BCVA) was 20/200. SES was performed to remove the SMH and treat the subretinal PCV lesions. After creating retinal detachment using a 38-gauge cannula, three subretinal 25-gauge trocars were inserted from the sclera to the subretinal space. Then, SES was performed under ophthalmic endoscopic observation with continued subretinal irrigation for maintaining the retinal detachment. After removal of the SMH, subretinal polyp-shaped nodular vascular lesions (polyps) and a branching vascular network, which is located inside the retinal pigmented epithelium, were identified. The sites that presumably originated from the aberrant vessels of the PCV and the associated polyps were coagulated using endodiathermy. After the subretinal procedure, the retina was flattened with fluid/air exchange, and silicone oil (SO) was injected into the vitreous cavity. The SMH completely disappeared after surgery. Although at one-month follow-up BCVA (20/250) was slightly worse than that before surgery, there was an improvement in postoperative retinal sensitivity in the macula compared to that before surgery. At the three-month follow-up, the SO was removed. The BCVA was 20/200 one month after SO removal. No postoperative complications occurred. Additional treatment was not required, including anti-vascular endothelial growth factor therapy, for PCV progression or SMH recurrence in the left eye till the final visit two years after surgery.Conclusion and importanceSES could effectively remove the old SMH, and the activity of PCV was suppressed by intraoperative subretinal coagulation. The retinal sensitivity of the macula improved after the SES. In addition, we observed subretinal polyps and a branching vascular network located internal to the retinal pigmented epithelium under intraoperative subretinal endoscopic observation. SES is a good surgical option for the removal of old SMH or treatment of subretinal lesions.
