Endoscopic precaruncular medial transorbital and endonasal multiport approaches to the contralateral skull base: a clinicoanatomical study.

Objective: Minimally invasive endoscopic endonasal multiport approaches create additional visualization angles to treat skull base pathologies. The sublabial contralateral transmaxillary (CTM) approach and superior eyelid lateral transorbital approach, frequently used nowadays, have been referred to as the "third port" when used alongside the endoscopic endonasal approach (EEA). The endoscopic precaruncular contralateral medial transorbital (cMTO) corridor, on the other hand, is an underrecognized but unique port that has been used to repair CSF rhinorrhea originating from the lateral sphenoid sinus recess.

Prospective Observational Trial of a Nonocclusive Dilatation Balloon in the Management of Tracheal Stenosis.

Objectives: Tracheal stenosis is a debilitating condition that often presents as an emergency and is challenging to treat. Dilatation may avoid tracheostomy or costly tracheal resection and reconstruction. Traditional dilators cause complete occlusion, preventing oxygenation and ventilation, limiting the safe duration of dilatation, and increasing the risk of hypoxic injury or barotrauma.

Orbito-Cranial Gunshot Injuries with Retained Sinonasal Bullets.

Introduction: Gunshot injuries to the sino-orbital region are rare. In South Africa, where gunshot injuries are common, sino-orbital gunshot injuries are encountered. Sino-orbital gunshot injuries are associated with trauma to surrounding facial and intracranial structures.

Contralateral Precaruncular Approach to the Lateral Sphenoid Sinus-A Case Report Detailing a New, Multiportal Approach to Lesions, and Defects in the Lateral Aspect of Well-Pneumatized Sphenoid Sinuses.

Introduction: Conventional surgical approaches to the lateral aspect of a well-pneumatized sphenoid sinus are associated with significant surgical morbidity. Transorbital endoscopic approaches have recently gained favor as an alternative approach to the skull base. We describe the use of a contralateral precaruncular endoscopic approach to provide a surgical pathway to the lateral aspect of the sphenoid sinus, allowing for improved and direct visualization of the surgical field, with limited morbidity.

Development of the international orbital Cavernous Hemangioma Exclusively Endonasal Resection (CHEER) staging system.

Background: Orbital cavernous hemangiomas (OCH) are the most common adult orbital tumor and represent an ideal index lesion for endonasal orbital tumor surgery. In order to standardize outcomes reporting, an anatomic-based staging system was developed.

Methods: An international, multidisciplinary panel of 23 experts in orbital tumor surgery was formed.

Use of surgical sealant in the prevention of pharyngocutaneous fistula after total laryngectomy.

Background: Pharyngocutaneous fistula is a major wound complication of total laryngectomy. Surgical sealants may be used to increase the strength and/or integrity of surgical repairs. The purpose of this study was to present our evaluation of the feasibility and utility of the application of sealant to the pharyngeal repair with the aim of reducing pharyngocutaneous fistula incidence.

Avoiding allogenic blood transfusions in endoscopic angiofibroma surgery.

Background: Surgical approaches for many tumours are often limited by blood loss, exposure and risk to vital anatomical structures. Therefore, the standard of care for certain skull base tumours has become endoscopic transnasal resection. Other surgical disciplines often use cell salvage techniques, but review of the otolaryngology literature revealed very few case reports.

Primary atypical carcinoid tumour of the sphenoid sinus rostrum.

Primary carcinoid tumors of the nasal cavity and sinuses are exceedingly rare. An accurate histopathological diagnosis is crucial to optimal investigation and management. We present a case of a primary atypical carcinoid tumor arising from the sphenoid rostrum without evidence of associated carcinoid syndrome.

Endotracheal tube cuff pressures - the worrying reality: a comparative audit of intra-operative versus emergency intubations.

Objectives: The primary aim was to assess the need for objective cuff pressure monitoring in the theatre complex and trauma centre at Groote Schuur Hospital, Cape Town, South Africa. Secondary aims were to determine whether the tube size, tube make or place of intubation affected cuff pressure.

Method: Endotracheal tube cuff pressures of 91 patients in the trauma centre and 100 patients in the theatre complex were randomly measured using a Mallinckrodt cuff pressure gauge.

Success rate of myringoplasty at Groote Schuur Hospital.

Objectives: The aim of this study was to determine the success rate of myringoplasty surgery performed at Groote Schuur Hospital and to evaluate some of the presumed prognostic factors.

Design: The study design was a retrospective analytical cohort. Setting.

Endoscopic trans-sphenoidal drainage of petrous apex cholesterol granulomas.

Cholesterol granulomas of the petrous apex are rare lesions that pose challenging surgical decisions and approaches when attempting surgical drainage. In this article we present 2 cases of successful surgical management using an endoscopic trans-sphenoidal approach and review the requirements and considerations for this procedure.

Malignant proliferating trichilemmal tumor involving the sinuses.

Proliferating trichilemmal tumor (PTT) is a rare adnexal neoplasm that arises from the outer sheath of the hair follicle. It is believed that PTTs originate in trichilemmal cysts. These tumors have the potential for malignant transformation; when this occurs, the tumor is known as a malignant PTT (MPTT).

Advances in endoscopic sinonasal and anterior skull base surgery.

Endoscopic transnasal surgery is rapidly replacing more radical external 'open' procedures. At Groote Schuur Hospital, Cape Town, we performed 94 advanced endoscopic sinonasal and anterior skull base procedures over a 2-year period. Most of these would previously have been performed using large external incisions requiring more invasive surgery with significantly higher morbidity.

South African survey on disinfection techniques for the flexible nasopharyngoscope.

This random survey was to determine the flexible nasopharyngoscope disinfection practice employed by South African otolaryngologists and to establish whether a breach in the disinfection process exists. The study also aimed to identify organisms most likely to be transmitted via endoscopy and to propose a protocol for the disinfection of the flexible nasopharyngoscope. A questionnaire regarding disinfection techniques used for the flexible nasopharyngoscope was sent to 90 otolaryngologists in South Africa.
