Prof. R.P. Sahi was our teacher in the Department of Surgery in King George’s Medical College, Lucknow. He was easily the best teacher in the campus. His baritone voice was renowned for its richness, strength and unmistakable quality, making it a defining feature of his aristocratic persona and a major factor in his enduring and universal popularity. This also made him instantly recognizable and command attention every time.
As
an undergraduate teacher he was matchless because he could sub-divide the most
complex subject into easily understandable bits, and once he taught a topic it
somehow got imprinted in our brain for life. There was a method in his teaching
which invariably simplified problems for even the back-benchers.
As
a resident in his unit, I found him to be an inspiring leader and an
outstanding post-graduate teacher with priceless qualities of a communicator, a
disciplinarian, a conveyor of information, an evaluator, a Unit manager, a
counselor, a member of many teams and groups, a decision-maker, a role-model,
and a surrogate parent all rolled in one. His umbrella of benevolence was
so reassuring that trainees got the best opportunity to express themselves. He
understood the strengths and weaknesses of his trainees and steered them
towards what would be best for them. Looking back, I can understand today how
important this individualized approach was in his unit.
Prof.
Sahi was a very sought after speaker, whether in surgical conferences or on
social occasions. He was invariably our first choice for C.M.E and Conference
inaugurations as well as after post dinner speeches. He somehow could palpate
the mood of the gathering and say exactly what the occasion demanded. When
Prof. P.C. Dubey was the Head of the Department of Surgery, Prof. Sahi was
entrusted with the responsibility of resident posting and academic scheduling
and the Department of Surgery was the best Department of the Medical College by
miles. When I was applying for my Microsurgery training fellowship in St.
Vincent’s Hospital, Melbourne, he and Prof. N.C. Misra gave me some glowing
recommendations.
After
his retirement he practiced in Krishna Medical Centre and mostly spent his time
in academic pursuits. He stays in Hazratganj in his old bunglow wnd enjoys his
retired life to the fullest.
I
came across a lecture he delivered to our batch in 1978 on ‘Swellings of the
Head & Neck’. He taught this vast topic in two lectures ‘Midline Swellings
of the Head & Neck’ and ‘Lateral Swellings f the Head & Neck’ and this
is the first lecture of this series.
Introduction
The deep fascia of the neck splits to envelope the Sternomastoid muscles. All swellings situated superficial to it are superficial swellings and all lying deep to it are the deep swellings.
Thus
superficial
swellings at this site are like any other site:
Skin Epidermoid or Pilar cyst
Fat Lipoma
Nerve Neurofibroma
Vessels Haemangioma
The
deep
swellings of the neck for the purpose of description are sub divided
into midline swellings and swellings in the lateral aspect of the neck.

Dermoids:
Can be present at the midline either on the vault or on the floor of mouth or
neck. They usually contain skin elements – sebum, hairs etc. They may scallop
the skull bones and rarely have intra cranial extension through a gap in the
skull. Treatment is excision and repair.
Fronto
nasal Meningocele / Meningo-encephalocele: Meningoceles are brilliantly trans
illuminent, cystic swellings, getting tense on coughing, crying or jugular
pressure. Meningomyloceles have ectopic brain tissue in them and so are not
trans illuminent. The inter orbital distance is widened – hypertelorism and
there are cross fluctuations between it and the fontannele. CT scan
demonstrates the gap in the skull and the treatment is excision, replacement of
herniated contents, and repair of the bony gap by bone grafts and surgical
correction of hypertelorism.
Lachrymal
sac swellings:
These are in the medial canthus of eye, usually inflammatory, and cause by
blockage of naso-lachrymal duct with resultant epiphora. Treatment is initially
conservative and if unsuccessful a DCR is done.
Rhinophyma: Sebaceous cyst
adenomatosis affecting the skin of nose. There are multiple sessile nodular
elevations over the nasal tip. Treatment is aesthetic rhinoplasty.
Gummata: These are seen in the
midline in the tertiary stage of Syphilis causing erosion of skin, mucous
membrane and bone. Midline structures like palate, hyoid, nasal bone, forehead
etc. can be involved. VDRL test clinches the diagnosis. It is getting more and
more uncommon in this antibiotic age.
Sub
mental Lymphadenitis: May be inflammatory or neoplastic and so the entire
drainage area – the tip of tongue, floor of mouth, incisors, symphyseal
alveolus should be examined for focus of infection or primary tumour. Other
lymph nodes should also be examined to rule out a primary Lymphoma.
Ranula: Myxomatous or mucoid
degeneration of sublingual salivary gland. It appears as a blue-grey domed cyst
in the floor of mouth, which is brilliantly trans illuminant. It has a tendency
to split the mylohyoid and project in the submental region- plunging ranula.
Treatment is excision by oral approach or marsupilization.
Sublingual
dermoid:
Sizable swelling filling and distorting the sublingual space, this dermoid is
located within the mylohyoid muscle or the intrinsic muscles of tongue.
Treatment is excision by sub mental approach.
Ludwig’s
Angina:
This is a form of cellullitis, which starts in the submandibular region and
spreads to the floor of mouth. It produces a diffuse swelling beneath the jaw
as well as the floor of mouth, often fixing the tongue. The unyielding deep
fascia of the neck pushes the oedema up towards the glottis and down towards
the mediastinum. Fatal septicemia, airway obstruction and death may result.
Treatment is emergency drainage and broad spectrum anti bacterial coverage for
Gram +ve, Gram –ve and anaerobes.
Thyroglossal
cyst:
These are cystic swellings mostly infrahyoid but may be suprahyoid as well and
they move both with deglutition and tongue protrusion. The Thyroid develops
from the foramen caecum and invaginates down as a tract called Thyroglossal
tract to become the Thyroid isthmus. The cyst can occur anywhere along this
tract. The cyst can become infected and form an abscess, which can be drained
like any other abscess and result in the formation of a fistula. Thyroglossal
fistula thus formed is never congenital, always acquired. These cysts are lined
by squamous, cuboidal or columnar epithelium and may have lymphoid and thyroid
tissue. They can turn malignant. Treatment of cyst and fistula is excision in
toto along with the entire tract right up to the foramen caecum, taking the
middle 1/3 of hyoid along with.
Subhyoid
bursitis:
Soft fluctuant swelling below the hyoid, it moves with deglutition and cannot
be distinguished from Thyroglossal cyst easily.
Lymph
node on crico thyroid membrane: A secondary deposit from a primary in the
larynx, if present an endoscopic laryngeal examination and biopsy is a must. It
also moves with deglutition.
Laryngocele:
A
soft, variable, unilateral or bilateral swelling, arising from the upper part
of Thyroid cartilage, this is a herniation of the laryngeal mucosa through a
gap in the thyrohyoid membrane. The swelling moves with deglutition and is
usually seen in musicians playing wind instruments like flute and bagpipes
Treatment is excision and repair.
Thyroid: This butterfly like
endocrine gland straddles the trachea and its isthmus is situated over the 3rd.and
4th. tracheal rings. It moves up with deglutition and may have
variable shape, size, consistency and tenderness. Lesions in Thyroid can be
inflammatory, neoplastic, autoimmune and idiopathic. Lymph nodes on either
sides of the neck and features of hypo and hyperthyroidism should always be
examined.
Thus
ended Prof. Sahi’s lecture on Midline Swellings of the Head & Neck. The
diagram that he made on the board, every time pops up in my mind, whenever I
see patients with midline head and neck swellings. This was once in a lifetime
teaching, which has stayed life-long!
