Kennedy pioneered endoscopic sinus surgery, a method which he named functional endoscopic surgery (FESS) and which became the standard surgical treatment for chronic rhinosinusitis. [2] [3] [4]

Kennedy was recognized by the American College of Surgeons as one of the most influential surgeons of the 20th Century. He developed the first rhinology fellowship thereby introducing the subspecialty of rhinology. [5]

Early life and education

Kennedy received his education at Ampleforth College in York, England, completing his university entrance exams in 1966. [6] He earned his M.D. from the Royal College of Surgeons in 1972 with numerous awards and medals. [6] [7] His post-graduate training included periods at St. Laurence's Hospital in Dublin, Ireland, along with various residencies in surgery and otolaryngology at Johns Hopkins University in Baltimore, MD. [6] [7]

After completing his residency in 1978, Kennedy joined the faculty of Johns Hopkins University. Having been exposed to Donald F. Proctor's teachings on nasal physiology and mucociliary clearance, he was influenced by the work of Prof. Walter Messerklinger in Austria, as a means to reduce the surgical morbidity and improve the results of sinus surgery. [8] [9] This involved a change in focus for disease management and the use of endoscopes and improved radiographic imaging for the diagnosis and management of sinus disease. [8] He conducted proof of concept research involving rabbit experiments. [8] This research led to the publication of initial articles on the theoretical foundations of functional endoscopic techniques and endoscopic sinus surgery. [8]

Kennedy received his board certification in otolaryngology in 1978 and became a fellow of the Royal College of Surgeons in Ireland in 1979. [10]

Career

Kennedy joined the University of Pennsylvania as Departmental Chair in 1991. [11] In various roles at Penn Medicine, he served as vice dean for Professional Services at the Perelman School of Medicine, and was senior vice president of UPHS. [12] He was involved in leading the Clinical Practices of the University of Pennsylvania and developing the Patient Facilitated Services Program. In his Vice Dean role, he introduced an organizational methodology for funds flow in academic medicine. [12] He currently holds the title of emeritus professor. [12]

During his career, Kennedy has served as president of the American Rhinologic Society, the International Symposium of Infection and Allergy of the Nose, the International Rhinologic Society and the American Academy of Otolaryngology–Head and Neck Surgery. [6] [13] Previously, he was the inaugural editor-in-chief of the International Forum of Allergy and Rhinology and American Journal of Rhinology. [14] [11]

In 2002, the David W. Kennedy, MD Professorship was established by his patients at Penn Medicine in recognition of his contributions to rhinology and his role in clinical practice at Penn Medicine. [15] David W. Kennedy, MD, Annual Lecture is also named after him. [16]

Research

Kennedy's research has focused on the pathogenesis of rhinosinusitis, mucociliary clearance, olfaction, and the management of nasal and sinus disease. He developed surgical instruments and improved techniques for endoscopic sinus surgery and minimally invasive skull base surgery. [10] Kennedy worked closely with James Zinreich, a radiologist at Hopkins to improve sinus radiographic imaging, developing appropriate CT and MR imaging to identify sinus disease, as well as to develop techniques for computer assisted surgery. [17]

His clinical expertise includes endoscopic sinus surgery, minimally invasive skull base surgery, CSF leak closure, endoscopic orbital surgery, and endoscopic pituitary surgery. [10]

<span class="mw-page-title-main">Otorhinolaryngology</span> Medical specialty

Otorhinolaryngology is a surgical subspecialty within medicine that deals with the surgical and medical management of conditions of the head and neck. Doctors who specialize in this area are called otorhinolaryngologists, otolaryngologists, head and neck surgeons, or ENT surgeons or physicians. Patients seek treatment from an otorhinolaryngologist for diseases of the ear, nose, throat, base of the skull, head, and neck. These commonly include functional diseases that affect the senses and activities of eating, drinking, speaking, breathing, swallowing, and hearing. In addition, ENT surgery encompasses the surgical management of cancers and benign tumors and reconstruction of the head and neck as well as plastic surgery of the face, scalp, and neck.

<span class="mw-page-title-main">Sinusitis</span> An inflammation of the mucous membrane that lines the sinuses resulting in symptoms

Sinusitis, also known as rhinosinusitis, is an inflammation of the mucous membranes that line the sinuses resulting in symptoms that may include thick nasal mucus, a plugged nose, and facial pain.

<span class="mw-page-title-main">Nasal polyp</span> Noncancerous growths within the nose or sinuses

Nasal polyps (NP) are noncancerous growths within the nose or sinuses. Symptoms include trouble breathing through the nose, loss of smell, decreased taste, post nasal drip, and a runny nose. The growths are sac-like, movable, and nontender, though face pain may occasionally occur. They typically occur in both nostrils in those who are affected. Complications may include sinusitis and broadening of the nose.

<span class="mw-page-title-main">Aspirin-exacerbated respiratory disease</span> Chronic inflammatory disease affecting the sinuses and lungs

Aspirin-exacerbated respiratory disease (AERD), also called NSAID-exacerbated respiratory disease (N-ERD) or historically aspirin-induced asthma and Samter's Triad, is a long-term disease defined by three simultaneous symptoms: asthma, chronic rhinosinusitis with nasal polyps, and intolerance of aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs). Compared to aspirin tolerant patients, AERD patients' asthma and nasal polyps are generally more severe. Reduction or loss of the ability to smell is extremely common, occurring in more than 90% of people with the disease. AERD most commonly begins in early- to mid-adulthood and has no known cure. While NSAID intolerance is a defining feature of AERD, avoidance of NSAIDs does not affect the onset, development or perennial nature of the disease.

<span class="mw-page-title-main">Nasal irrigation</span> Personal hygiene practice for rinsing out nasal passages

Nasal irrigation is a personal hygiene practice in which the nasal cavity is washed to flush out mucus and debris from the nose and sinuses, in order to enhance nasal breathing. Nasal irrigation can also refer to the use of saline nasal spray or nebulizers to moisten the mucous membranes.

<span class="mw-page-title-main">Empty nose syndrome</span> Medical condition

Empty nose syndrome (ENS) is a clinical syndrome, the hallmark symptom of which is a sensation of suffocation despite a clear airway. This syndrome is often referred to as a form of secondary atrophic rhinitis. ENS is a potential complication of nasal turbinate surgery or injury. Patients have usually undergone a turbinectomy or other surgical procedures that injure the nasal turbinates.

Balloon sinuplasty is a procedure that ear, nose and throat surgeons may use for the treatment of blocked sinuses. Patients diagnosed with sinusitis but not responding to medications may be candidates for sinus surgery. Balloon technology was initially cleared by the U.S. Food and Drug Administration in 2005 and is an endoscopic, catheter-based system for chronic sinusitis. It uses a balloon over a wire catheter to dilate sinus passageways. The balloon is inflated with the goal of dilating the sinus openings, widening the walls of the sinus passageway and restoring normal drainage.

<span class="mw-page-title-main">Functional endoscopic sinus surgery</span> Surgery to enlarge the paranasal sinus drainage pathways

Functional endoscopic sinus surgery (FESS) is a procedure that is used to treat sinusitis and other conditions that affect the sinuses. Sinusitis is an inflammation of the sinuses that can cause symptoms such as congestion, headaches, and difficulty breathing through the nose.

<span class="mw-page-title-main">Inverted papilloma</span> Medical condition

An inverted papilloma, also known as Ringertz tumour, is a type of tumor in which surface epithelial cells grow downward into the underlying supportive tissue. It may occur in the nose and/or sinuses or in the urinary tract. When it occurs in the nose or sinuses, it may cause symptoms similar to those caused by sinusitis, such as nasal congestion. When it occurs in the urinary tract, it may cause blood in the urine.

Endoscopic ear surgery (EES) is a minimally invasive alternative to traditional ear surgery and is defined as the use of the rigid endoscope, as opposed to a surgical microscope, to visualize the middle and inner ear during otologic surgery. During endoscopic ear surgery the surgeon holds the endoscope in one hand while working in the ear with the other. To allow this kind of single-handed surgery, different surgical instruments have to be used. Endoscopic visualization has improved due to high-definition video imaging and wide-field endoscopy, and being less invasive, EES is gaining importance as an adjunct to microscopic ear surgery.

Laryngeal cysts are cysts involving the larynx or more frequently supraglottic locations, such as epiglottis and vallecula. Usually they do not extend to the thyroid cartilage. They may be present congenitally or may develop eventually due to degenerative cause. They often interfere with phonation.

Antral lavage is a largely obsolete surgical procedure in which a cannula is inserted into the maxillary sinus via the inferior meatus to allow irrigation and drainage of the sinus. It is also called proof puncture, as the presence of an infection can be proven during the procedure. Upon presence of infection, it can be considered as therapeutic puncture. Often, multiple repeated lavages are subsequently required to allow for full washout of infection.

Caldwell-Luc surgery, Caldwell-Luc operation, also known as Caldwell-Luc antrostomy, and Radical antrostomy, is an operation to remove irreversibly damaged mucosa of the maxillary sinus. It is done when maxillary sinusitis is not cured by medication or other non-invasive technique. The approach is mainly from the anterior wall of the maxilla bone. It was introduced by George Caldwell (1893)and Henry Luc (1897). The maxillary sinus is entered from two separate openings, one in the canine fossa to gain access to the antrum and other in the naso antral wall for drainage.

<span class="mw-page-title-main">Fungal sinusitis</span> Inflammation of the paranasal sinuses due to fungal infection

Fungal sinusitis or fungal rhinosinusitis is the inflammation of the lining mucosa of the paranasal sinuses due to a fungal infection. It occurs in people with reduced immunity. The maxillary sinus is the most commonly involved. Fungi responsible for fungal sinusitis are Aspergillus fumigatus (90%), Aspergillus flavus, and Aspergillus niger. Fungal sinusitis occurs most commonly in middle-aged populations. Diabetes mellitus is the most common risk factor involved.

Nasal surgery is a medical procedure designed to treat various conditions that cause nasal blockages in the upper respiratory tract, for example nasal polyps, inferior turbinate hypertrophy, and chronic rhinosinusitis. It encompasses several types of techniques, including rhinoplasty, septoplasty, sinus surgery, and turbinoplasty, each with its respective postoperative treatments. Furthermore, nasal surgery is also conducted for cosmetic purposes. While there are potential risks and complications associated, the advancement of medical instruments and enhanced surgical skills have helped mitigate them.
