Management of frontal sinus fungal osteomyelitis in the COVID 19 era: A case series.

The aim of this study was to review different approaches and outcomes in the management of post-COVID-19 frontal sinus fungal osteomyelitis. The study included 19 patients with frontal sinus fungal osteomyelitis. The main line of treatment was surgical debridement (sequestrectomy). Approaches included combined external and endoscopic approaches (n = 15) and pure endoscopic approaches (n = 4) according to the extent and accessibility of the sequestrum. Postoperative healing was satisfactory in all patients. All patients returned to their normal daily activity within 4-6 weeks, without residual or recurrent frontal sinus infection, osteomyelitis or need for revision procedures. Within the limitation of this case series, it seems that there is no need to adopt a new therapy regimen for treatment of frontal sinus fungal osteomyelitis because the conventional and well-known treatment approach combining surgery and antifungal drugs seems to work well. However, early, and adequate debridement and sequestrectomy is crucial. Furthermore, an open approach may be required according to the extent of osteomyelitis.

Nasal Spine of the Frontal Bone: A Consistent Landmark for Safe Outside-In Frontal Drill-Out.

BACKGROUND: Outside-in frontal drill out entails drilling the frontal sinus floor in the midline before identifying and dissecting the frontal recesses. It is a more direct approach, especially in revision surgery or cases with challenging anatomy. OBJECTIVES: The aim of this study was to highlight the anatomical and surgical concepts for easy and safe outside-in frontal drill out by a preclinical anatomic study on cadaveric heads. In addition, to review our experience with this approach over a 5-year period for challenging frontal sinus pathologies. METHODS: The study included 2 sectors; a preclinical study, in which 5 cadaveric heads were dissected and studied to identify and standardize the anatomical landmarks of this approach. This was followed by a clinical case series which included 22 patients with challenging frontal sinus pathologies that were treated with this proposed approach. RESULTS: We concluded from the anatomic study that the nasal spine of the frontal bone (NSFB) and its anatomical orientation in relation to the nasal branch of the anterior ethmoidal artery (NBAEA) is a consistent landmark that enables the surgeon to identify the correct coronal trajectory of drilling to avoid injury of the cribriform and the skull base. The clinical case series included 22 patients that were successfully treated with the proposed approach. No intraoperative nor postoperative complications were reported in this study. Long-term follow-up showed that the frontal neo-ostium was patent in all cases (n = 22). CONCLUSION: Outside-in frontal drill-out is a safe and easy approach; especially in challenging frontal sinus pathologies; using the NSFB and its anatomical coronal orientation to the NBAEA as a consistent landmark, anterior to the skull base. This approach offers early, safe, and direct bone removal without the need for initial identification and dissection of the frontal recess.

Challenging tracheal resection anastomosis: Case series.

OBJECTIVES: This study was conducted to review our experience in Otorhinolaryngology Department, Mansoura University Hospitals, Egypt, in the last 2 years in the management of high-risk patients who underwent cricotracheal resection due to different pathologies. METHODS: This case series included nine patients with severe, grade III or IV subglottic / cervical tracheal stenosis. These patients were considered high risk patients due to unusual pathology / etiology of stenosis or associated surgical field morbidity. Four patients had recurrent stenosis after previous unsuccessful cricotracheal resection, three patients had subglottic stenosis due to external neck trauma which compromised the surgical field. One patient had upper tracheal neoplasm, and in 1 patient there was upper tracheal stenosis associated with tracheo-esophageal fistula. RESULTS: Successful decannulation was achieved in all patients (n = 9) without any reported major intraoperative or postoperative compilations. CONCLUSION: Cases of subglottic / upper tracheal stenosis due to uncommon pathologies like neoplastic lesions, external neck trauma compromising the surgical field and revision cricotracheal resection, can be successfully managed by cricotracheal resection. However, a highly skilled team, well familiar with these surgeries, is mandatory to achieve an optimum outcome.

Endoscopic stapedotomy: Merits and demerits.

INTRODUCTION: Surgical microscopes are still preferred to perform stapes surgery; but the use of the endoscopes would offer much benefits such as good panoramic view and easy accessibility to the oval window niche, the stapes and facial nerve. In this study, we aimed to analyze and compare the outcomes and complications of endoscopic versus microscopic stapes surgery. PATIENTS AND METHODS: This work was done at the Department of Otorhinolaryngology, Faculty of Medicine, Mansoura University, Egypt, between September 2015 and July 2016. The patients; diagnosed as having otosclerosis and full filled the selection criteria; were randomly divided into 2 groups. RESULTS: The group A (microscopic group) included 28 patients (aged 19-60 years) and the group B (endoscopic group) included 14 patients (aged 22-56 years). Mean follow-up durations were 4.5 months (1-8.5) in the endoscopic group and 5.5 months (1.5-8) in the microscopic group. The difference in preoperative and postoperative air-bone gap in two groups was statistically significant (p = 0.031). But there was no statistical difference for hearing results between two groups and the two techniques have similar audiological outcomes. The main merits of endoscopic stapedotomy are the good quality panoramic image, well identification and visualization of vital structures of the middle ear, minimal handling of chorda tympani nerve if needed with practically no curettage of bony wall. CONCLUSIONS: The present series shows that it is possible to perform stapes surgery using only the 4mm in diameter and 18cm long endoscopes of different angulations, without major difficulties.

Surgical correction of bifid nose.

OBJECTIVES: Evaluation of the aesthetic outcome and functional aspect after surgical correction of bifid nose by combined Millard forked flap with external rhinoplasty BACKGROUND: Bifid nose is a rare congenital anomaly that results during facial development but the explicit mechanism is not clearly understood. Clinical findings are quite variable with a wide range of severity. Surgical correction still represents great challenge to facial plastic surgeons; extensive deformities in many cases, rarity of condition and paucity of publications are contributing factors. METHODS: Surgical correction of six patients with bifid nose by a combined Millard forked flap with external rhinoplasty RESULTS: The aesthetic and functional outcomes were acceptable for all patients and parents. There were no considerable postoperative complications. CONCLUSIONS: This approach is highly effective for various grades of bifid nose. Early management is preferable to avoid psychological morbidity. Secondary rhinoplasty is usually needed for cosmetic refinement.

Cervical sympathetic schwannoma with postoperative first bite syndrome.

Extracranial schwannomas occurring in the head and neck region may arise from cranial, peripheral or autonomic nerves. Determination of the nerve of origin is not often made until the time of surgery. Schwannomas arising from the cervical sympathetic chain are extremely rare. These interesting tumors along with schwannomas in general and the remaining class of neurogenic tumors are known for their ability to mimic the physical and radiological findings of carotid body tumors. Surgery is the treatment of choice and major complications are infrequent. However, we report a case of cervical sympathetic chain schwannoma with postoperative first bite syndrome.
