Medical Corner: Otolaryngology Pioneers of Transsphenoidal Surgery

 This month the PNA Medical Corner focuses on an article co-authored by Dr. Edward Laws, a longtime member of the PNA. The research looks at the considerable impact two early otolaryngologists, Markus Hajek and Oskar Hirsch, had in developing endonasal transsphenoidal pituitary surgery.

Hajek and Hirsch: Otolaryngology Pioneers of Endonasal Transsphenoidal Pituitary Surgery

PMID: 36420787 DOI: 10.1002/lary.30496

Abstract

Objective: To evaluate the historical descriptive origins of the extracranial transnasal transsphenoidal route to the sphenoid sinus and sella turcica focusing on the works of two otolaryngologists: Markus Hajek (1861-1941) and Oskar Hirsch (1877-1965).

Data sources: A collection of primary references of author publications, and contemporary references and textbooks.

Review methods: Primary references were reviewed with specific focus on surgical routes to the sphenoid sinus and sella turcica. Chronology was cross-referenced with contemporary publications by contemporaries. Translations from German were conducted by author AM when necessary.

Results: Markus Hajek elegantly described the surgical approach to the posterior ethmoids and sphenoid sinus in 1904 using a transnasal route. Building on this foundation, Oskar Hirsch described the fully extracranial endonasal transethmoid transsphenoidal approach in 1909. He was first to describe surgical entrance to the sella using this exclusively unilateral endonasal route, which he demonstrated on a cadaver. He reports performing this procedure on a live patient in April, 1910, under local anesthesia in stages over 5 weeks. For better exposure, Hirsch consolidated his method with Killian’s submucosal window resection of the posterior nasal septum allowing for bilateral access to the sphenoid sinus and sella, and completed a single stage procedure on a patient in June 1910.

Conclusion: Oskar Hirsch was the first to describe and perform a stepwise surgical approach to the sella using an exclusively extracranial, endonasal, transethmoid, and transsphenoidal approach. He built upon his mentor Markus Hajek’s approaches to the posterior ethmoid cells and sphenoid sinus.
